    摘要： A meter unit, co-located to an electric meter, and a building unit, co-located with an energy management system, cooperate to deliver electric meter relay pulses from the electric meter to an energy management system via a wireless link. Meter relay pulses are input to the meter unit from the electric meter, relay states and pulse counts are transmitted to the building unit, and the states of the relays and pulses are regenerated by the building unit as outputs to the energy management system. The pulses output from the building unit perform as though they were created by the meter originally, but without the traditional wired connection. The system provides for error correction should a pulse count transmission be lost, as well as repeating of an end-of-interval pulse so that the energy management system may synchronize its data collection and operation to the measurements from the meter.

    摘要： In a cable or CATV system consisting of a central station with a television transmitter connected via a television transmission cable to a plurality of remote stations each with a television receiver, there is provided apparatus for signalling between the central and remote stations. The apparatus includes at the central station pulse generating means for transmitting via the cable variable sets of packets of first frequency signals followed by a packet of second frequency signal. Each of the remote stations is assigned a specific set of the first frequency signals. In each remote station the packets of first frequency signals are converted to a set of first pulses and the packet of second frequency signal to a second pulse. Counting means count the first pulses of the set and if the count at the time the second pulse is received agrees with a count assigned to the remote station an indication is given.

    摘要： It has one or more controls (1) that communicate with one or more receiving hosts (2, 3, 4) that govern the opening and closing of certain doors or accesses. Each control (1) has a single pushbutton (5), in which according to the number, duration of the presses and/or distances between the control (1) and the hosts (2, 3, 4), said remote control (1) can control and be controlled with respect to any number of hosts (2, 3, 4), according to pre-established modes. Communication between the remote controls (1) and the hosts (2, 3, 4) is bi-directional and includes a secret code by means of an algorithm (RPDA) specifically developed for the system which consists of a pre-coded preamble that heads all the communication messages and requires a satisfactory response at the end of the flow of messages.

    摘要： An electronic circuit architecture time-division-multiplexes analog sensorignals from a distributed sensor array onto a common transmission line in a digitally encoded format. The architecture synchronizes the multiplexing, sampling and encoding to ensure a proper settling of the analog data signals and is fabricated to be compact with low power consumption for a cost-effective implementation for a number of sensors.
