Granted: 2000-01-11
Abstract: A memory mapped keyboard controller (108) within a peripheral controller (103) for use in an Industry Standard Architecture (ISA) computer (102) provides a method and apparatus for efficiently monitoring and reading a keyboard switch matrix. In a first mode of operation, the controller (108) activates all the columns and monitors all the rows in the switch matrix to detect when any one or more of the rows becomes active, indicating that at least one key on the keyboard (112) has been pressed. When any row in the matrix is detected as active, then the keyboard controller ( 108) enters a second mode wherein it selectively activates individual columns and monitors the rows in the switch matrix to detect which row and column contain the activated switch. When the switch location is determined, this location is interpreted by the keyboard controller (108) into a scan code for the ISA computer (102).

Filed: 1992-06-03
Granted: 2006-04-04
Abstract: An apparatus and method for performing speech signal compression, by variable rate coding of frames of digitized speech samples (10). The level of speech activity for each frame of digitized speech samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. A lowest rate of the set of rates corresponds to a detected minimum level of speech activity, such as background noise or pauses in speech, while a highest rate corresponds to a detected maximum level of speech activity, such as active vocalization. Each frame is then coded according to a predetermined coding format for the selected rate wherein each rate has a corresponding number of bits representative of the coded frame. A data packet is provided for each coded frame with each output data packet of a bit rate corresponding to the selected rate.

Abstract: A communication system in which, a subscriber terminal moves between networks having different number plans is described.  The moved subscriber terminal can receive the same service as that of the network from which the subscriber terminal has moved (movement originator network) without being conscious of the movement. In the system, when the subscriber terminal moves between the networks having the different number plans, the movement of the subscriber terminal is registered in the network to which the subscriber terminal has moved (movement destination network), data is exchanged with the movement originator network, an allocated number correlative table is prepared and stored in the movement destination network; while, a movement destination number correlative table is prepared and stored in the movement originator network. When the moved subscriber terminal issues a call to another network, a call control is transferred from the movement destination network to the movement originator network on the basis of the allocated number correlative table and carried out in the movement originator network on the basis of the movement destination correlative table.

Title: Method for analyte classification by sc profiles
Inventor: KAUVAR LAWRENCE M
IPC: G01N33/53
Filed: 1992-04-02
Granted: 2002-06-11
Abstract: The precision of identification of analyte composition in a sample, where the possible analytes each provide a series of va-lues for characteristic parameters; in particular where the parameters are generated by cross-reaction with specific binding rea-gents, is enhanced by applying pattern recognition techniques. Samples to be tested are evaluated with respect to each survey par-ameter to obtain a pattern of parameter values with respect to each analyte at a given concentration. In the case of the use of a panel of specific binding reagents, the samples to be tested are reacted with this panel and the affinities at various analyte concen-trations are determined. This results in a databank of "SC profiles" for known concentrations of each analyte. This databank is stored in a computationally accessible form, which then can be matched against SC profiles obtained by testing unknown sam-ples.

Granted: 2002-01-01
Abstract: Voltage and current on a power transmission line are first obtained, filtered and converted to digital representations. The positive sequence components of the voltage and current are determined and the impedance at the relay is then calculated from those positive sequence voltages and currents. The positive sequence impedance is converted into a magnitude and phase angle representation and then compared against a load pattern which is also represented by magnitude and phase angle representations. If the calculated impedance at the relay is within the lead impedance pattern, the distance relay is prevented, i.e, blocked, from sending an output signal to trip a circuit breaker protecting the transmission line.

Abstract: The present invention relates to a method for detecting the onsetof atherosclerosis and for detecting the degree of athero-sclerosis. Accordingly, one aspect of the present invention correlates data obtained from arteries having a measured amount of stenosis with actual arterial data (blood volume change vs. cuff pressure) obtained from a patient which is converted into data re-lating to the patient's arterial peak compliance. Another aspect of the present invention detects the onset and the degree of athero-sclerosis by classifying the shape of a curve obtained by relating arterial blood volume change with cuff (20) pressure. Two de-vices can be used, an electrical impedance plethysmograph (10) and a volume plethysmograph.
