A Layered Service Provider (LSP) is a feature of the Microsoft Windows Winsock 2 Service Provider Interface (SPI). A Layered Service Provider is a DLL that uses Winsock APIs to insert itself into the TCP/IP stack. Once in the stack, a Layered Service Provider can intercept and modify inbound and outbound Internet traffic. It allows processing all the TCP/IP traffic taking place between the Internet and the applications that are accessing the Internet (such as a web browser, the email client, etc). For example, it could be used by a computer security program, which analyzes the traffic in search for viruses or other threats before transferring it to the final application of the traffic. The Winsock Service Provider Interface (SPI) API provides a mechanism for layering providers on top of each other. Winsock LSPs are available for a range of useful purposes, including parental controls and Web content filtering. The layering order of all providers is kept in the Winsock Catalog.

The IEEE-488.1 standard greatly simplified the interconnection of programmable instruments by clearly defining mechanical, hardware, and electrical protocol specifications. For the first time, instruments from different manufactures were connected by a standard cable. This standard does not address data formats, status reporting, message exchange protocol, common configuration commands, or device specific commands.
The IEEE-488.2 standard enhances and strengthens the IEEE-488.1 standard by specifying data formats, status reporting, error handling, controller functionality, and common instruments commands. It focuses mainly on the software protocol issues and thus maintains compatibility with the hardware- oriented IEEE-488.1 standard. IEEE-488.2 systems tend to be more compatible and reliable.


The findmeSPOT Connect GPS Device
I used to use the SPOT Connect GPS tracker from www.findmeSPOT.com.:
This device, now outdated, is controlled from a cell phone via Bluetooth and transmits data via satellite to the findmeSPOT servers. The data sent is of two basic types: text messages and tracking GPS position data. The text messages are predefined and saved on the cell phone (and synched with the findmeSPOT server when Internet connectivity is available). The messages are sent as either text messages (SMS) or email to a list of predefined recipients. GPS coordinates are attached to the message so a recipient can see where you were when the message was sent.
Separate from the text messaging feature, the user can turn on “Tracking.” When Tracking is on GPS coordinates are automatically sent every 10 minutes. These tracking points are relayed to the findmeSPOT.com server and saved for online viewing. The user usually sets up a public or private (password protected) “Share page” and emails its URL to interested people beforehand. Thus at any time anyone with the Share page URL (and password if it’s private) can see the track in real time. (Well, almost real time. There is a short delay)
Finally, SPOT Connect can an SOS message that is relayed by findmeSPOT.com to the nearest emergency response agency. So far, I’ve not had to use this feature.
I now use a Garmin 735XT watch.

But in a recent research of mine, I've come across really interesting facts about listeners, which of course I'll share with you over here.
Listener lies at the top of the Oracle net foundation layer. When an instance is initiated, listener establishes communication pathway to oracle. It also establishes communication pathway between databases, in case, when multiple database or instances runs on one single computer.
Listener identifies the database instance through service names. It communicates with the database using listening endpoints which are port numbers, and can be dynamically registered with listeners. Following is the way how communication is established between client and database:
Client Request reaches listener--> listener selects appropriate handler--> Listener determines that service is available --> Directs the client request to the service --> If a listener receives an incoming request before the respective instance has been registered, the listener rejects the request --> receives the service answer -->Provides connection between client and the database.
During service registration, an instance background process provides listener the following information.
- Names of the database services provided by the database
- Name of the instance associated with the services and its current and maximum load
- Service handlers available for instance, including their type, protocol addresses.
So next time when you're connected to an oracle database using any application, just remember the role listener is playing as a broker between application and database.
Have a great life….


Overseas travelling is finally back in full swing for many after a two-year hiatus. The travel-starved majority will no doubt be gearing up for their eagerly-awaited escapades in the next few months. Among the most crucial preparations is to figure out ways to get connected when abroad, of course.

Wireless barcode scanners are simply barcode scanners that are not linked to a Computer or some other terminal with a cable.
Wireless barcode scanners can be divided into two groups
Wireless scanners are handheld units that connect to their base stations with Bluetooth or some other radio frequency.
Portable Data Terminal are also at times referred to as wireless barcode scanners. These units normally have a display and keypad.
These scanners essentially work the same as the normal corded scanners but without a cable. They use either Bluetooth or some other radio frequency to communicate with their base stations.
The base station which is also the charger is connected to a computer with a cable.
Scanners that use Bluetooth Technology can also connect directly to Bluetooth enabled Tablets, Smart phones and such like.
An example of a Wireless Barcode Scanner is the Datalogic QBT2430. The scanner is placed in its base station to charge its battery. The base station is connected to a computer with a USB cable. On this particular model the effective working range between the base station and scanner is 25 meters.
A microUSB port on the scanner foot allows an auxiliary method for battery recharging and also allows the product to be used without the base station.
The advantage of using a Wireless Barcode Scanner
The scanner has no cable restricting the movement of the operator. Instead of bringing heavy or larger objects to the scanner and computer, the user can take the scanner to the items that need to be scanned.
There is also no cable that can be damaged or get worn due to constant movement of the scanner.
But what happens if you move out of the working range between the scanner and its base – Many of the scanners like the Datalogic QBT2430 has an on board memory that stores the scanned data. The data is transmitted to the base station when the scanner gets back in range.
Wireless QR Code Scanner
The 2D enabled barcode scanners like the QBT2430 can read and decode QR Codes. QR Codes are just a 2D symbology. The QBT2430 is also able to read barcodes directly from a mobile device display.
For more information and pricing on the Datalogic QBT2430 Bluetooth Wireless Scanner visit JNS Technologies Website
Portable Data Terminal
As mentioned before – the Portable Data Terminals are also sometimes referred to as Wireless Barcode Scanners.
The Cipherlab 8200 Portable Data Terminal with the 2D area imaging scan module is able to read and decode QR Code and all other 2D Barcodes. The 8200 is known as a batch unit – meaning it has an internal memory. All the scanned and keyboard entered data is stored and downloaded when its inserted in its dock.
The Cipherlab 8231 looks similar to the 8200 Batch but it has Bluetooth and WiFi (802.11) communications.
These units are ideal for stock taking, asset tracking etc. For more information and pricing on the Cipherlab 8200 and 8231 contact JNS Technologies

China has rolled out the world’s fastest internet network. It is capable of transmitting data at 1.2 terabits per second (Tbps). The new Chinese internet system is based on a technology called OTN (Optical Transport Network). However, it uses lasers to transmit data over optical fibers.
China has announced the creation of the fastest internet network globally. The new network, developed by Chinese tech company Huawei in collaboration with China Mobile, Beijing’s Tsinghua University, and Cernet (a government-funded education and research network), boasts speeds of 1.2 terabits (or 1,200 gigabits) per second. Although these speeds are currently theoretical and won’t be available to consumers immediately. They signify a significant advancement in internet capabilities.
The new Chinese internet system is based on a technology called OTN (Optical Transport Network), which uses lasers to transmit data over optical fibers. The network covers a distance of 1,800 miles with optic fiber cables between Beijing and the south. It aims to facilitate faster data transfers, enhance stock trading, and has implications for national security. The backbone network, responsible for moving internet traffic across different locations, supports data transfers from technologies like 5G and electric vehicles.
The announcement was made during a press conference, and the network began operating and undergoing tests in the summer. It launched about two years earlier than predicted by experts. Chinese President Xi Jinping sees this development as a crucial step in establishing China as a “cyber power” and accelerating the promotion of core internet technologies.
While this advanced network primarily focuses on infrastructure rather than home internet speeds, it could offer a foundation for Chinese businesses requiring high bandwidth. Wu Jianping, a professor at Tsinghua University overseeing the project, emphasized that the system, both software and hardware, is made, produced, and independently controlled in China, making it the most advanced network globally.
The timing of this announcement coincides with President Biden’s meeting with President Xi Jinping in San Francisco, amid months of tension between the two countries. Unlike areas such as AI, semiconductors, or wireless networking technology, this internet infrastructure development does not pose a direct threat to the US but could potentially benefit Chinese businesses.

Amateur or “Ham” Radio is a popular hobby and service in which licensed Amateur Radio operators (hams) operate communications equipment. Although Amateur Radio operators get involved for many reasons, they all have in common a basic knowledge of radio technology and operating principles, and pass an examination for the FCC license to operate on radio frequencies known as the “Amateur Bands.” These bands are radio frequencies reserved by the Federal Communications Commission (FCC) for use by ham radio operators.
Amateur Radio has many aspects. One can explore electronics, antenna design, software, digital communications, emergency preparedness, satellites, weather-spotting, competitive operating, world-wide “DX-ing”, or just use ham radio as a powerful communications tool, especially when widespread disasters strike. Emergency responding agencies depend on their communications network when all else has failed.
The Barnstable Amateur Radio Club is an active group with activities throughout the year. They participate in the American Radio Relay League field day, the Boy Scouts of America’s Jamboree-on-the-Air, and Amateur Radio Direction Finding, which is a racing sport that combines radio direction finding with the map and compass skills of orienteering. It is a timed race in which individual competitors use a topographic map, a magnetic compass and radio direction finding apparatus to navigate through diverse wooded terrain while searching for radio transmitters.
Feel free to stop by on Saturday and say hello to the hams. They’ll be the guys with the antenna!


The PCS Paddle Shifter provides upshift and downshift commands to a PCS transmission controller, a PCS GSM push button shifter, or a GM mechatronic transmission such as the 6L80. The paddle shifter is available for either 5/6-bolt or 9-bolt steering columns. The paddle shifter communicates wirelessly to a receiver module that interfaces the CAN network. The wireless communication drastically simplifies the wiring, requiring only the horn wire to be used to power the paddle shifter. The paddles were precisely engineered to provide a positive detent feel the moment the switch is activated to eliminate any guessing when the transmission was commanded to shift.
An optional display mounted in the center of the paddle unit will display vehicle and transmission parameters such as:
|• Current Gear||• TCC Slip %|
|• Driveshaft RPM||• Throttle Position|
|• Manifold Pressure||• Turbine RPM|

Equal-Cost Multi-Path (ECMP) Routing
The ASA supports Equal-Cost Multi-Path (ECMP) routing.
You can have up to 8 equal cost static or dynamic routes per interface. For example, you can configure multiple default routes on the outside interface that specify different gateways.
route outside 0 0 10.1.1.2
route outside 0 0 10.1.1.3
route outside 0 0 10.1.1.4
In this case, traffic is load-balanced on the outside interface between 10.1.1.2, 10.1.1.3, and 10.1.1.4. Traffic is distributed among the specified gateways based on an algorithm that
hashes the source and destination IP addresses, incoming interface, protocol, source and destination ports.
ECMP Across Multiple Interfaces Using Traffic Zones
If you configure traffic zones to contain a group of interfaces, you can have up to 8 equal cost static or dynamic routes across up to 8 interfaces within each zone. For example, you can configure multiple default routes across three interfaces in the zone:
route outside1 0 0 10.1.1.2
route outside2 0 0 10.2.1.2
route outside3 0 0 10.3.1.2
Similarly, your dynamic routing protocol can automatically configure equal cost routes. The ASA load-balances traffic across the interfaces with a more robust load balancing mechanism.
When a route is lost, the device seamlessly moves the flow to a different route.

Key Developer Features
Send data from your server to users' Android-powered devices
This could be a lightweight message telling your app there is new data to be fetched from the server (for instance, a movie uploaded by a friend), or it could be a message containing up to 4kb of payload data (so apps like instant messaging can consume the message directly). GCM Architectural Overview.
Send "send-to-sync" messages
A send-to-sync (collapsible) message is often a "tickle" that tells a mobile application to sync data from the server. For example, suppose you have an email application. When a user receives new email on the server, the server pings the mobile application with a "New mail" message. This tells the application to sync to the server to pick up the new email. Send-to-sync messages.
Send messages with payload
Unlike a send-to-sync message, every "message with payload" (non-collapsible message) is delivered. The payload the message contains can be up to 4kb. Messages with payload.
Faster, easier GCM setup
Streamlined registration makes it simple and fast to add GCM support to your Android app. Learn more »

Alexander Graham Bell was a Scottish-born scientist, inventor, engineer and innovator who is credited with patenting the first practical telephone this date in 1876.
Bell’s father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell’s life’s work. His research on hearing and speech further led him to experiment with hearing devices that eventually culminated in Bell being awarded the first U. S. patent for the telephone on this date in 1876. Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Later, on March 10th that same year, Bell first successfully transmitted speech, saying “Mr. Watson, come here! I want to see you!” using a liquid transmitter.
An inventor named Elisha Gray had filed “an intent” to get a patent for a very similar invention earlier that same day with the U. S. Patent Office. Bell made his application several hours later and, since it was an actual application rather than just an intent to file an application, Bell was awarded the patent. The U.S. Patent Office’s decision to award the patent to Bell remains a point of contention among historians and members of the Gray family to this day. (from Wikipedia)


Chip-Scale Atomic Optical Clock
CSOC wants to make a chip-scale atomic optical clock. Here, an on-chip mode-locked laser at 1310 nm is used to pump a silicon nitride resonator. The generated octave spanning comb is sent to a 1f-to-2f on-chip interferometer to determine the carrier-envelope offset of the comb through self-referencing. Further, the light of an on-chip frequency doubled narrow linewidth Distributed Feedback (DFB) laser is locked to an Rb transition in vapor as a second reference. These error signals, together with the comb's repetition rate frequency, allow to synthesize the clock signal.
Micro-transfer printing enables full integration
Heterogeneously integrated III/V quantum dot mode-locked laser
It is well known that quantum dot based optical layers offer important advantages for realizing integrated mode-locked lasers such as broadband gain, and high power.
Thus far the lower quality substrate of commercially available QD epi wafers prevented their use in hybrid III-V silicon active devices realized using bonding.
Recently UGENT managed to resolve this problem and demonstrated for the first time InGaAs QD-based mode lasers operating at 1300 nm.
Here, we will for the first time demonstrate QD mode-locked lasers on silicon nitride using microtransfer printing integration techniques.
Further, by using a low loss silicon nitride cavity low noise operation is guaranteed as recently shown by the UGENT.
SiN Resonator - dispersion engineered
Low-Loss Integrated Photonics
The active devices will be integrated on Ligentec's low-loss silicon nitride platform, through the development of an evanescent coupling interface for heterogeneous integration.
In a first stage, devices will be prototyped separately, where they benefit from low propagation losses for the external cavities.
In the next stage, all optimized devices are interconnected on the same platform.
Ligentec's technology offers rapid prototyping within the project, while enabling scaling to higher volumes on 200-mm wafers.
The spectroscopy unit will provide the absolute stable and accurately known reference signal, which will be down divided by the integrated frequency comb to produce a highly precise clock signal. Therefore, the unit will be composed of the frequency-doubled CW laser, a highly integrated feedback electronics module and a commercially available mm-scale spectroscopy. The overall optical assembly will be mounted on a miniaturized optical bench.

Amplifiers & control kit
After site survey has highlighted the project requirements then the correct amplifier can be chosen and from there the need for EQ, limiters, feedback control units & salve amplifiers can be addressed. Running speakers over a 100V speaker line or low impedance is a decision that will dictate the choice of amplifier, in addition knowing the total number of inputs into the system will influence the choice of mixer, be it mixing desk or mixer amplifier. Our sales team and engineers can guide you through these decisions.
From column speakers to satellite speaker systems we can recommend suitable speakers which will blend into the churches environment. Reverberation is an ever present problem in churches with large amounts of highly reflective surfaces. Consequently, the correct type and positioning of speakers is vital in achieving clear voice reproduction throughout. It is also important to consider all the possible uses for the sound system before settling on the right type, especially when the space to to be used in different layout and configurations.
Fixed or wireless, Omni directional or hyper cardioid, hand held or lapel clip. All microphone types have their place in church environments and it is our job to guide you through the process of choosing correct microphones.
Sound systems present a very particular set of challenges. A correctly designed and installed church PA system will bring clear, intelligible sound reinforcement to a church. MCN Sound & Security have over 30 years’ experience of installing church sound systems across the UK.
Reverberation & feedback are very prominent issues when installing church sound systems (particularly in older churches) and the balance between what is aesthetically pleasing and acoustically suitable must be carefully explored in order to perform well and please both the church committee and members of the congregation.
Induction Loop Systems
An induction loop system is an audio amplifying system that enables hearing aid users to listen to conversations, performances or the television without the excessive background noise that is produced from the hearing aid’s inbuilt microphone when they increase the volume. The sound source, for example a microphone on a desk, is plugged into a loop amplifier which feeds a loop cable fixed around the perimeter of the room.
The audio signal is transmitted from the loop cable and picked up by the coil housed within the hearing aid. The hearing aid user simply switches their hearing aid to the T position to hear clearly. Please note, only hearing aids with a T switch will pick up the signal from a induction loop system.
Italian Electronic Church Bell System
We also install Electronic Church Bell systems. These units can store up to 1,000 melodies and have approximately 500 hymns built in.
These bell systems can be programmed to automatically play at Mass times as well as the Evangelist at 12pm and 6pm.
You can also pre-program hot keys to play Funeral and wedding tones.
If you want to play one of the 500 hymns built in, you simply look in the booklet and enter the code for the desired hymn and press ok.
These electronic bell systems are then connected to some Tannoy speakers, mounted in your church Tower.
Multi zone paging system allows paging up to 12 zones, utilizing a single channel amplifier by activating the speaker line selector from the desktop remote microphone
