Abstract:
Circuitry to remove switches from signal paths in integrated circuit programmable gain attenuators. Programmable gain attenuators and programmable gain amplifiers commonly switch between signal levels using semi-conductor switches. Such switches may introduce non-linearities in the signal. By isolating the switches from the signal path linearity of the PGA can be improved.
Abstract:
Provided is a circuit to perform single-ended to differential conversion while providing common-mode voltage control. The circuit includes a converter to convert a single-ended signal to a differential signal and a stabilizing circuit adapted to receive the differential signal. The stabilizing circuit includes a sensor configured to sense a common-mode voltage level of the differential signal and a comparator having an output port coupled to the converter. The comparator is configured to compare the differential signal common-mode voltage level with a reference signal common-mode voltage level and produce an adjusting signal based upon the comparison. The adjusting signal is applied to the converter via the output port and is operative to adjust a subsequent common-mode voltage level of the differential signal.
Abstract:
Binary indications are converted to an analog representation with significant reduction in ringing at the transitions between successive binary indications and in the period during each binary indication. The binary indications are disposed in a row-and-column matrix to provide a thermometer code. Each stage of the converter includes a decoder and latch arranged so the decoder inputs settle before the latch is set by the clock pulses. The stages are implemented in complementary CMOS. Complementary transistors are biased so one transistor of the pair is driven to the rail while the other transistor of the pair floats. A dummy CMOS transistor is used to balance the number of transistors in the decoder paths.

The induction system senses unusual signals and sends them to the automatic dial system and the alarm system. The automatic dial system is able to automatically dial a preset telephone number to notify a related person. The mobile telephone transmitting-and-receiving system is able to transmit or receive signals. The alarm system is able to light up a warning light and give out sound. The automatic charge system is able to make up a self-supplying power through voltage drop and electricity storage. The power delay connection system is able to delay for a period of time and then convey power to all the foresaid systems.
Abstract:
Improved apparatus for mechanically stirring a quench-cooled subfluidized particulate bed of polymerized monomer lowers lumping of polymer particles by using substantially contiguous paddle stations disposed along the drive shaft within the reactor in combination with a plurality of sub-stations in at least one paddle station class, each sub-station having a width along the shaft of no more than 50 percent of the total width of the paddle station, and sub-station paddles attached to the shaft at each sub-station so as to sweep through the particulate bed. In some embodiments, a first class of stations is, advantageously, disposed within the reactor along a portion of the drive shaft in repeating groups of at least two stations and a second class of stations with sub-stations is disposed within the reactor along another portion of the drive shaft, preferably in repeating groups of at least one more than the number of stations in the repeating group of the first class, to further reduce lumping of polymer particles.

Abstract:
An image projection system includes a scaler IC, a micro-projector, a video connector, and a controller. The video connector is coupled to the scaler IC and the micro-projector. The controller controls the video connector and the scaler IC to form a first signal path mode and a second signal path mode. The video connector transmits a first image signal from the scaler IC for external displaying in the first signal path mode. The video connector receives a second image signal from a peripheral device and passes the second image signal to the micro-projector for projection in the second signal path mode.
Abstract:
A system for managing medical information includes a host device for installation at a first location, an image capturing device, and an end device for installation at a second location. The host device encodes medical information into a barcode, and outputs the barcode to an information carrier. The image capturing device captures an image of the barcode on the information carrier so as to create a barcode image. The end device decodes the barcode image for obtaining the medical information encoded by the host device.
