  • Patent number: 5856792
    Abstract: An interrupt apparatus for remotely controlling a potentiometer is comprised of an encoder for generating a pair of quadrature output signals whenever the encoder becomes rotated. The pair of signals are sent to a pair of D flip-flops for detecting a rising or falling edge of one of the signals. The pair of D flip-flops sends an interrupt signal to a microprocessor when the signals indicate that the encoder has been rotated. Either one of a pair of AND gates will output a high signal to set a third D flip-flop when motion is in the counter-clockwise direction. After being interrupted, the microprocessor reads the direction signal from the third flip-flop, resets the three flip-flops so that subsequent motion may be detected, updates the value of resistance stored in memory, and outputs the magnitude of the resistance in digital form.

  • Patent number: 5852409
    Abstract: A remote telemetry metering system, includes one or more battery-powered metering units and a central data collection unit, each including a radio transceiver. The central data collection unit transmits a signal including power down time information and transmits instructions, which is received by each metering unit. Each metering unit extracts the power down time information and transmits instructions from the signal and, if appropriate, transmits data in response to the data transmit instructions; this data being collected by the central data collection unit. The metering units then interrupt the power supply to their transceivers for a period of time which is dependent upon the power down time information. The central data collection unit delays, for a slightly longer period of time before transmitting a further signal via its transceiver, at which time the power supply to the transceiver of each metering unit has already been resumed.

  • Patent number: 5852408
    Abstract: A system includes a medication dispensing device that is adapted for dispensing a medication to a patient at a predetermined time interval and includes a method for the detection of the timely removal of the medication from the device. When the medication is not timely removed from the device a signal of non-compliance is generated and is received by an alarm system that is adapted to summon help. According to a first embodiment the alarm system places a telephone call to a care-giver or, if the care-giver is unresponsive, to an alternate care-giver who in turn makes contact with the patient. According to a second embodiment the alarm system places a telephone call to a central monitoring station which attempts to make contact with the patient by use of a two-way speaker phone that is included in the alarm system.

  • Patent number: 5828323
    Abstract: An ergonomic keyboard utilizing ten keys which are activated in pairs to produced coding signal representing alphabetic symbols of a conventional computer keyboard. The keyboard is operated as a replacement or in parallel with a conventional computer keyboard. Each key corresponds in position with each finger on a hand. By pressing two keys, unique letters and functions are produced. As the number of unique binary combinations of ten elements is 45, the ten-key keyboard system is capable of representing at least 26 characters plus the function keys of a standard 101-key computer keyboard. The structure enables greater speed through efficiency in finger movement and easy learning.

  • Patent number: 5821876
    Abstract: The present invention provides a circuit breaker control arrangement that is reliable, accurate and cost-effective to manufacture, install and maintain. This circuit breaker arrangement also provides increased modularity by alleviating the need for installing wires to connect each circuit breaker with the control station. The present invention uses circuit breakers that contain internal control technology for interrupting and establishing an associated current path. At least one coded signal designates each circuit breaker, and a communication bus carries these coded signals to each circuit breaker. Decoding technology located on each circuit breaker determines whether the coded signal corresponds to that circuit breaker. If the coded signal does correspond to that circuit breaker, then the decoding technology responds by sending the appropriate response signal over the communication bus, and the circuit breaker's internal control technology either interrupts or establishes the associated current path.

  • Patent number: 5818353
    Abstract: Self leveling apparatus that includes a frame, a device that is to be leveled, and a leveling mechanism such as a double ring gimbal having an inner gimbal ring and an outer gimbal ring. The outer gimbal ring is secured to the frame and the inner gimbal ring is secured to the device and to the outer ring. The inner ring comprises a viscous or preloaded bearing that allows the device to swing around an inner ring axle to thereby level itself in that axis and prevent spurious movement of the device. The outer gimbal ring and inner gimbal ring are attached by outer axles that comprise a viscous or preloaded bearing that allow the inner gimbal ring to swing around the outer axles thereby level the inner gimbal ring in that axis and prevent spurious movement of the device. A disclosed embodiment of the invention includes a magnetometer sensor that is coupled to signal processing and telemetry electronics and a power source that are leveled to keep axes of the sensor oriented along horizontal and vertical axes.

  • Patent number: 5801645
    Abstract: The apparatus and method of the present invention overcome the difficulties of balancing paired LVDT probes via provision of a quick and inexpensive process that can be implemented in either hardware or software. In particular, a software method is provided for determining a balance correction factor for paired probes in a LVDT gauging system. The balance correction factor is found through a procedure in which an operator moves a part under measurement within a fixture to which the probes are installed. The balance correction factor is then used to mathematically normalize A/D counts from individual paired probe circuits into a single result for each pair.
