Like an ordinary dust particle, Smart Dust will remain suspended in the environment acting like electronic nerve endings for the planet, monitoring almost everything on earth. Smart Dust is a concept originated out of a research project by the United States Defense Advanced Research Projects Agency (DARPA) and the Research And Development Corporation (RAND) in the […]
THE GPS Technology Throughout time people have developed a variety of ways to figure out their position on earth and to navigate from one place to another. Early mariners relied on angular measurements to celestial bodies like sun and stars to calculate their location. The 1920s witnessed the introduction of more advanced technique-radio navigation-based at […]
The SIDAC, or SIlicon Diode for Alternating Current, is a semiconductor of the thyristor family. Also referred to as a SYDAC (Silicon thYristor for Alternating Current), bi-directional thyristor breakover diode, or more simply a bi-directional thyristor diode, is technically specified as a bilateral voltage triggered switch. Its operation is identical to that of the DIAC; […]
Portable fuel cell Commercialisation –catalysing the industry. Electricity is becoming as much a problem in the 21st century as it was a solution in the 19th and 20th centuries. Global demand for electrical energy is increasing, in areas as diverse as mobile phones and household lighting, driven by the basic power needs of emerging economies and ever […]
Originally created by Apple and standardized in 1995 as the specification IEEE 1394 High Performance Serial Bus, FireWire is very similar to Universal Serial Bus (USB). Also known as i.Link or IEEE 1394 is a personal computer (and digital audio/digital video) serial bus interface standard, offering high-speed communications and isochronous real-time data services. FireWire has replaced Parallel […]
Bluetooth is a current industry standard for short-range wireless connectivity. Bluetooth technology is widely used in consumer electronics for short-range wireless data transfer, like printers and digital cameras. It operates efficiently within the range of 20-25 ft in the environment without WLAN equipments. Bluetooth signals operate in the same frequency range as WI-FI (802.11b, g) […]
What is Ultra-Wideband Technology? Ultra-Wide Band (UWB) is a communication method used in wireless networking that uses low power consumption to achieve high bandwidth connections. It offers many advantages, especially in terms of very high data transmission rates. Adopting Ultra-Wideband for Memsen’s file sharing and wireless marketing platform.
Bit-banging is a method of using general-purpose I/O lines to emulate a serial port. Microcontrollers that include serial-port modules like SPI[tm] and I2C[tm] manage all synchronization and timing signals, and this activity is transparent to the user. With bit-banging each write to the port causes a single transition at the port pin. And it’s up […]
