The widespread Conficker computer worm has crawled into hundreds of medical devices, including MRI systems, at dozens of hospitals in the United States and other countries.The San Jose Mercury News reported that the worm has not resulted in causing harm to patients, but poses a potential threat to hospital operations.
‘Cuts are reportedly in store, both first desktop and laptop lines.’ Faced with slumping sales and stinging criticism from competitor Microsoft over its high prices, Apple is reportedly going to try a price cut to spur its computer sales. While Apple’s general sales have been saved by its iPhone, its computer sales, both for laptops and desktops have slumped. […]
The SED technology has been developing since 1987. The flat panel display technology that employs surface conduction electron emitters for every individual display pixel can be referred to as the Surface-conduction Electron-emitter Display (SED). Though the technology differs, the basic theory that the emitted electrons can excite a phosphor coating on the display panel seems […]
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 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; […]
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 […]
