Abstract: A data link controller receiver is disclosed that includes a series of shift registers and a bit counter that counts the number of received bits. When an end of frame character is received, the value in the bit counter which represents the bit residue is supplied to a bit adjustment counter. The bit adjustment counter is is employed to control the operation of the shift register containing the bit residue during a byte adjust operation, in a manner which enables the shift register containing the bit residue to be clocked until the value in the bit adjustment counter is indicative of the number of bits in a defined byte. Accordingly, the bit residue is serially shifted until the most significant bit of the shift register is filled. In addition, a mechanism is provided for loading zeros into the shift register during the byte adjust operation.

Abstract: A frequency domain signal processing an analysis method and apparatus displays, plots and makes measurements upon electrocardiographic signals (ECG) recorded from the body surface. Both the graphic plots and the numeric parameters measured reveal abnormalities of electrical conduction within the heart thought to be important in the identification of patients at risk of serious disturbances of heart rhythm including sudden death. The invention employs frequency analysis of short overlapping segments of ECG signal to create a three dimensional map ("spectrocardiogram") whose axes are time, frequency and power thus disclosing changes in the frequency content of the ECG signal over short intervals of time. In addition to the Fourier analysis itself, the method of apparatus provides a wide choise use-selectable signal pre-processing, post-processing, display and plotting options as well as performing custom mathematical computations upon the frequency spectra to distinguish and quantify visually apparent differences between normal and abnormal spectrocardiogram.

Abstract: A transmit-receive station connected to a high speed ring bus carrying data signals that may be received from and sent to each station on the ring bus has two sources of transmit clocking signals. One source is based on the frequency and phase of data signals received on the ring bus from another station and the other source is a local crystal oscillator having essentially the same frequency as the first source but in an indeterminate phase. When changing the source of clocking signals for transmission of data originating at the station, bit slippage may be minimized by providing the local oscillator output signal in four phases and using the phase most nearly aligned with the other clocking signal when the change is made. 
     Control of access to transmit by a station employs a token having a message field of seven bits and a access control bit. Each message frame ready for transmission is assigned a priority number which is used with the token to cause the data message frames at different stations to be transmitted in a sequence based on their respective priority numbers.

Abstract: A self correcting infrared intrusion detection system (30) primarily for elevator doors establishes multiple through-beams (44) to intelligently detect passengers and adjust for environmental changes. Beam patterns are monitored by software that differentiates between intrusions and malfunctions and adjusts itself automatically when hardware partially fails in the absence of an intrusion. The system automatically chooses and executes two different door-width sensing routines. A plurality of spaced apart transmitter stations (43) mounted vertically apart in one door faces a plurality of spaced apart, receiver stations (45) mounted in the other door. Each transmitter station periodically radiates modulated light towards the receivers in the opposite door. A main control circuit monitors all receivers (45), controls all the transmitters (43), and executes the software. The presence or absence of a Shepherd beam established diagonally between the doors determines whether the system executes a "long beam" pattern when the doors are far apart or a "short beam" pattern when the doors are closer together. Gate networks can be jumpered to variably configure the transmitters and receivers. The software adjusts for broken parts or semi-permanently interrupted beams by automatically marking out inoperative pathways, thus enabling the system to continue functioning with alternative beam sequences evolved on the job. Marked out beams are periodically re established by the software. Diagnostic indicators monitor blocked beams to warn service personnel.

Abstract: An elastic-matching alignment technique for providing an averaged prototype in a handwriting recognition system that improves the alignment of parametric representations of recognized characters to be averaged. The point-to-point correspondence resulting from an elastic match of two characters is obtained by using backpointers during the calculation of the match.

Otherwise, the character is averaged into the closest prototype of its class to provide a new average prototype.
