Patent NO-180358-C (NO)
Inventor: BERNSTEIN ALEC
IPC: G05D23/19
Filed: 1991-06-06
Abstract: An interactive electronic thermostat operates to communicate with an installed through an audible or visual display and keypad to instruct the installer to perform tasks and enter observations to effect proper connections at the thermostat of heater/air conditioner wires in spite of the absence of labels identifying the functions of those wires. The thermostat requires entry of coded indicia representing operator-observed conditions in the system in response to displayed instructions carried out by the operator. Control circuits are automatically assigned functional tasks in response to the operator-observed conditions entered into the system. Different program routines are invoked depending upon the number of system wires and the type of heater/air conditioner being controlled. Under appropriate circumstances, messages are displayed informing the operator/homeowner that the thermostat is incompatible, or has no advantageous use, with the heater/air conditioner. In one embodiment the installer need only connect the wires to the thermostat terminals one time; the thermostat reconfigures its internal connection paths in response to installer-entered indicia to assure proper control of the system.

Abstract: A voice data transmission system and method which can reduce a transmission delay time and can remove the unnatural conversation of a received voice due to the truncation of head part of the voice. The signal transmission side of the voice data transmission system, when a voice detection signal is generated.  continuously  transmits.  at a transmission rate faster than a usual transmission rate,  a first voice data block at the time of generation of the voice detection signal as well as voice data blocks which are followed by the first voice data block and which correspond to a time duration from the generation time of the voice detection signal block to a predetermined time. In a voice detection mode. the data trans-mission side subjects voice data to a blocking operation and. after the blocking operation is completed, transmits the voice data block. The signal reception side of the data transmission system, when receiving a voice packet signal following by the continuation of a predetermined time of silence (voice absent state), estimates a fluctuation absorbing delay time for the voice packet signal on the basis of transmission delay times between packets  corresponding to  its head part,  attaches packets corresponding in number to the estimated fluctuation absorbing delay time to the head part of the received voice packet signal.

Abstract: A connector which can couple a first profiled member having an internal compartment behind a slotted wall with a tubular second profiled member has an open-ended housing which is installed in the second profiled member and a one-piece profiled plate-like coupling member in the housing. The coupling member has two integral prongs with mirror symmetrical claws at their free ends, and followers adjacent the claws.      The housing has integral cams which can stagger the claws by way of the followers in response to longitudinal displacement of the coupling member in the housing as a result of rotation of an eccentric which normally extends into a window of but is depressible into the second profiled member to permit insertion or removal of the connector. The claws can be introduced through the slot in the wall of the first profiled member to be thereupon staggered by the followers in cooperation with the cams in response to rotation of the eccentric in a direction to move the claws toward the housing. The coupling member has an integral spring which biases the eccentric into the window of the second profiled member.

Title: Method and apparatus for determining anaerobic capacity
Inventor: YORIOKA GERALD N
IPC: A61B5/22
Filed: 1990-08-08
Granted: 2000-04-18
Abstract: A method and apparatus for defining and determining a value for an anaerobic capacity parameter is disclosed. The anaerobic capacity parameter is defined as the time required to completely deplete the subject's anaerobic capacity given maximum mechanical exertion by the subject under controlled conditions. A value for the anaerobic capacity parameter for a subject is generated via a testing system. The testing system includes an exercise device (12), a power characteristic sensor (14), and a processing unit (16). The exercise device (12) includes a movable component, the movement of which can represent a measurement of distance. The exercise device creates a load on the subject. The power characteristic sensor (14) is used to sense the movement of the movable component and the load imposed on the subject. Power characteristic data, e.g., movement and load data, are generated by the power characteristic sensor. The processing unit (16) is connected to the power characteristics sensor (14) such that power characteristic data and control signals are transferred therebetween. The improvement in the testing system is the inclusion of a main control program in the processing unit (16). The main control program controls the recording of power required to move the movable component is derived from the power characteristic data over a test period. A set of power values indicative of the power required to move the movable component is derived from the power characteristic data. An anaerobic capacity value is determined by analyzing the logarithmic decay of the derived power values. The time to completely deplete a logarithmic function approximating the derived power values is the anaerobic capacity value. Values for parameters such as will power, total power, and power potential are also derived from the analysis.

Targets are provided on the floor at various locations from which camera shots are to be taken.  The dolly is moved from one target to the vicinity of another target according to a learned sequence of movements controlled by a remote dolly computer.  The learned sequence of movements is taught with the aid of a joystick, and the motions are replayed based on dead reckoning.  In order to correct translational and angular errors in the position of the dolly at the destination target, optosensors are provided on the dolly for use in detecting and reorienting the dolly relative to the destina-tion target.  The open loop control of dolly movement can be taught with a control stick and the motions replayed based on dead reckoning.

Abstract: A microprocessor based circuit breaker has a removable rating plug which provides a reference for the current rating of the breaker. The removable rating plug also has an EEPROM to which the microcomputer of the circuit breaker writes for storage, the number of operations of the circuit breaker operating mechanism and a trip history of the breaker in the form of a count of the number of trips weighted by the magnitude of the trip current. The rating plug is periodically removed and plugged into a portable programmer which selectively displays the number of operations and operating history of the circuit breaker.      The programmer clears this operating data when recorded and can write into the EEPROM the style and serial number of the circuit breaker with which the rating plug is to be used.

Abstract: A high transconductance field effect transistor is realized by controlling the doping level in a conducting channel buried beneath a heterointerface.  In one exemplary embodiment, a channel comprising an undoped, high mobility, narrow band gap quantum well in combination with an intermediate band gap layer is formed beneath a heterointerface.  The heterojunction interface is between a wide band gap layer and the quantum well region.  A charge sheet having the same conductivity type as the wide bandgap layer is formed near the heterointerface. Advantageously, the transconductance is enhanced by conduction in the undoped filled quantum well region.
