The Uninterrupted Power Supply in an IC . Cymbet Corporation announced the availability of the EnerChip™ CC CBC3105 smart solid state battery. The CBC3105 combines the award winning EnerChip battery with integrated input power conversion, battery management and regulated output capabilities. The Cymbet EnerChip™ CC is a smart rechargeable solid state battery Uninterrupted Power Supply (UPS in a Chip™) that provides power backup to microelectronic devices when main power fails. The EnerChip CC provides power supply monitoring and switches over to the internal solid state backup battery when the supply drops below a set threshold. The EnerChip CC product family can provide anywhere from several hours to several weeks of backup time.  Simple Uninterrupted Power Supply in an IC Circuit Diagram   The CBC3105 is an ideal solution for design engineers who need a compact device to back-up a Real Time Clock or Microcontroller during power failure where coin cell batteries or super ...

Pointers and Scales in Measuring Instruments Instrument scales and pointers may be considered together in two classes: (A)     Those intended for reading quickly (in the case of switch board instruments at a distance), and (B)      Those intended for close accurate reading for portable instruments. Pointers: The shape and size of the pointers depends upon the type of instrument. The weight and inertia of pointer must be reduced so as to reduce the load on the bearing and to avoid necessity of damping torque. The pointer motion is usually limited by buffer stops little more than the scale. These stops are constructed as very light springs so that the pointer is not bent when it strikes them sharply on a sudden overload or reversal of the operating current. fig 1. Pointer The pointers for switch board and panel instruments should be so that the position of the pointer is conspicuous. The pointers are usually broad or carry broad targets at their ends. Al...

Citing unnamed supply chain sources, as well as what we’re guessing are some better informed sorts within Samsung, the Korea Times claims that the phone will land in February at the Mobile World Congress. The handset is apparently set to hit retailers shortly after in March – just nine months after the release of its predecessor. In news that’s unlikely to surprise anyone on nodding terms with prevailing trends in smartphone upgrades, Samsung’s new kit will purportedly pack a larger five-inch OLED screen – up from the S3’s 4.8-inches - and international 4G LTE support. An unnamed deepthroat said: “Samsung wants to keep its one-year product schedule and the Galaxy S4 will be the first to match that strategy. “The S4 will see some external changes but retain its popular rectangular shape with rounded corner concept.” News of Samsung’s plans comes as it recently announced that the S3 has now sold some 20 million units, making it the company’s fastest-selling phone ever.
