Abstract: In a signal processing system, a weighting function is applied to incoming signal pulses in response . to a signal edge detector (48). A weighting function is applied both to the detected large signal pulse and to the time surrounding the signal pulse within a window but at different times so that small signals, if they occur overlapping in time with the leading or trailing edge of the detected large signal, are weighted independently of the large signal. The weighting functions are multiplied with the incoming signals and then sent to conventional signal processing apparatus (58).

Abstract: This invention relates to a semiconductor sensor for detecting external physical forces, such as acceleration, contact pressures, air pressures, mechanical vibrations, etc. The semiconductor sensor according to this invention is characterized by the use of compound semiconductors of high piezoelectricity, such as GaAs, etc. Conventionally sensors of the cantilever type, diaphragm type, etc. are made of silicon. These prior art sensors have low detection sensitivity, and their characteristics tend to deteriorate. The sensor according to this invention is made of GaAs, which has high piezoelectricity and can retain good characteristics of the semiconductor even at high temperatures and includes a field-effect transistor formed on the GaAs for sensing a stress. The FET is driven by a constant current or a constant voltage so as to detect a change of an electrical characteristic (e.g., threshold characteristic) due to a stress. The structure of the sensor according to this invention enables the sizes of the sensors not only to be diminished but also to reduce the fabrication costs. When a stress is applied to the FET, the transconductance changes, and the temperature changes, consequently the I-V characteristic changes. An a.c. signal biased by a direct current is supplied to the gate of the FET, and a drain current is detected in an a.c. component and a d.c. component so as to detect a   temperature concurrently with a detection of a stress.

Abstract: A method and an apparatus are disclosed for improving the anti-jam performance of a processing circuit to increase conversion gain and reduce small signal suppression resulting from processing a phase modulated input signal accompanied by jamming interference. Input signals are each segregated into signal chips by a matched filter (23), and by an adaptive threshold circuit (13) in accordance with a predetermined relative threshold. The threshold is said to repeatedly distinguish a predetermined number of signal chips having greater signal amplitude. The absolute amplitude threshold level may, therefore, vary in accordance with the particular signal chips forming each input signal segment. A phase quantizer (29) operates to extract phase information from the signal chips. A phase correlator (15) operates to apply a first weighting gain factor to signal chips equal to or exceeding the threshold, and a second weighting gain factor to the remaining chips, the first weighting gain factor being greater than the second weighting gain factor.

Abstract: A method of communication in a computer system is provided for transferring information between multiple, concurrently operating programs, each of which may have a respective window display. The user communicates with each of the application programs through the window display as well as through an input device, such as a mouse or keyboard. A list of information codes is registered with a dispatcher program for each of the application programs which requires data. One or more of the application programs generate templates which include data and a corresponding information code. The generated templates are transmitted to the dispatcher program. The dispatcher program then compares the information code in the received template to the registered list of information codes to find any matches and thereby identify the one or more application programs which have registered to receive the information in the received template. The dispatcher program then transmits the received template to each of the identified application programs. Information communication is therefore carried out between multiple operating programs without user direction for the steps of the communication process.

Abstract: A digital data interface for high speed asynchronous data transfer is described. The design is nominally intended for integration onto the component chips in communications systems. The system is described with respect to its realisation in CMOS IC technology. The techniques involved, however, may easily be applied to other technologies. The interface employs Manchester Bi-­Phase Mark encoding of the clock and data to allow extraction of the clock and data signals at the receiver (7). Furthermore, use of this Manchester code allows code violations to be easily employed as frame markers for synchronisation means. The essence of the clock extraction and data detection circuit (9, 11) is the use of calibrated delay line elements to suppress data transitions within the coded input signal, thus allowing the clock transitions to be detected from which the clock is then generated.
