Abstract: A meter for collecting and communicating flow data for a commodity including a liquid, a gas, or electricity transported via a metered system, using wireless data transfer, the meter including a housing, a sensor for sensing a resource flow rate, and a register for registering data input thereto, the register including a processor for processing data input thereto. A wireless transmitter is also provided for outputting the sensed data from the meter or receiving instruction information through an antenna. A TouchRead interface may also be provided for outputting the sensed data from the meter or receiving instruction information from a device external to the meter, which receives data output from the meter and/or outputs instruction information to the meter. The sensor, the processor, and the wireless transmitter are disposed within the housing.

Abstract: An electronic expander (12) allows for reading a plurality of utility meters (14) with an interrogation device (30) via a common electronic access point (16) wherein the interrogation device (30) interrogates and receives meter usage data from all of the meters (14) during a single coupling with the common electronic access point (16).

Abstract: The present invention is a dial in-bound MIU capable of deriving its operating current from a telephone line. The MIU is coupled to the telephone line using conventional practices. The MIU has the capacity to initiate data transmission at a predetermined time or upon demand by the customer or the utility company. The MIU includes a microprocessor which serves as the command processing center for the MIU. The microprocessor also manages all time dependent functions for the MIU. When the microprocessor determines that data transmission is required, the MIU dials up a central computer using a modem built into the MIU circuitry.

Abstract: The remote instrument reading and telemetry system of the present invention includes at least one instrument link interconnected to a data gathering device and a remote station interrogation apparatus. The interrogation apparatus and instrument link both include radio transmitters and receivers so information and instructions can be communicated between them. In the interrogation mode, the interrogation apparatus instructs the instrument link to transmit information (e.g., data from the data gathering device) in a specified manner, within certain time frames, and in a specific frequency channel. Before requesting the transmission of information, the interrogation apparatus determines which of the available reply radio channels is the best for transmission of information and instructs the instrument link to use this reply channel.

Abstract: A call in-bound remote reading and data collection system for the remote reading of utility meters, including a data processor and a remotely located meter interface unit (MIU) interconnected to at least one utility meter to be read. Also disclosed is a meter interface unit and a method for the remote reading of utility meters and the collection of data. The data processor collects, stores and processes data and includes a modem to interconnect the data processor to conventional telephone lines. The MIU is interconnected to the telephone lines and the data processor, to transmit scheduled meter reading to the data processing means, when a prespecified interval has elapsed. The MIU is also interconnected to transmit unscheduled or demand meter readings when the MIU receives telephone line transmissions requesting such a reading (e.g. receipt of a specified tone). A modem is used to interconnect the MIU so it can communicate over the telephone lines.

Abstract: A utility data gathering system is disclosed as comprising a register including a series of index members coupled to a meter mechanism. Each index member includes a plurality of contacts and a switch arm moveable with its index member. The meter mechanism is responsive to utility consumption for moving the index members to positions indicative of the utility consumed, whereby each switch arm completes in normal operation a circuit with just one of its plurality of contacts dependent upon the position of its index member. A digital computer is programmed for performing first and second scans of each contact of each index member to obtain corresponding first and second sets of data indicative of a completed circuit through the switch arm and contacts of each index member. The completed circuit data obtained from each of the first and second scans are compared and if the circuit data of the first and second scans are different, an alarm manifestation is generated.

Abstract: A three phase motor acceleration control fires SCR's to supply successively longer current pulses to the motor. The SCR's are controlled by comparing a chopped reference ramp and individual trigger ramps.
