Publication number: 20080036622Abstract: A method for use in a power line communication systems for an electrical distribution system (1) to quickly and accurately poll electrical meters (6) installed at user facilities to determine if an outage has occurred at a facility. An outbound communications message is transmitted to the meter at the facility requesting a short response consisting of a bit pattern that is either partially or completely known to the receiver.

Finally, the method includes receiving the piece of data at the base station and using the receipt thereof to determine which of the possible data element combinations the stored data element is.Type: ApplicationFiled: May 3, 2007Publication date: November 8, 2007Inventors: David W.

Patent number: 7256695Abstract: An electronic system includes a reader and a remotely powered and remotely interrogated sensor transponder. The sensor transponder includes a coil or an antenna, a switched reactance circuit, a processor, and a sensor. The sensor transponder receives power radiated from the reader to the coil or antenna. The sensor uses the power for sensing. The sensor transponder is capable of processing sensor data in the processor and transmitting the sensor data to the reader using the switched reactance circuit. In one embodiment, the receiver coil or antenna is part of a resonant tank circuit which includes an impedance matching circuit. The impedance matching circuit is connected to the receiver coil or antenna to provide greater current to the sensor or other power-using device than would be available to the sensor or other power-using device if the sensor or other power-using device were connected between the first and second end. The impedance matching circuit can be two or more taps to the coil or antenna.Type: GrantFiled: September 23, 2003Date of Patent: August 14, 2007Assignee: Microstrain, Inc.Inventors: Michael John Hamel, Steven W.

Patent number: 7254372Abstract: A method and system for transmitting, receiving, and collecting information related to a plurality of working components, such as street lamps, allows for efficient and effective monitoring and controlling of working components through short-distance radio communications at low power levels. In a preferred implementation of the present invention, a communications network includes a plurality of transceiver modules, each of which is secured and operably connected to a working component. These transceiver modules transmit and receive radio communications or “messages” representative of the status of the working component from one another in a controlled manner, with each message ultimately being directed to an area control module.Type: GrantFiled: September 14, 2004Date of Patent: August 7, 2007Assignee: Tyco Electronics Logistics A.G.Inventors: Gerald E. Janusz, Stephen C. Payne, Timothy J. Prell, Paul van der Pol

Patent number: 7212112Abstract: Among the embodiments of the present invention are pest control devices (1010, 1110, 1210) each operable to detect the presence of pests. The pest control device (1010, 1110, 1210) has a bait (1032) that is consumed or displaced by one or more species of pest, a pest sensing circuit (1052, 1152, 1252), and a monitoring circuit (1069, 1169, 1269). The pest sensing circuit (1052, 1152, 1252) can be altered by pest activity. The monitoring circuit (1069, 1169, 1269) detects this alteration and reports it automatically or in response to an external stimulus or interrogation to indicate pest presence.Type: GrantFiled: April 3, 2003Date of Patent: May 1, 2007Assignee: Dow AgroSciences LLCInventors: Daniel T. Barber, Don Black

Patent number: 7196628Abstract: A self powered monitoring device for monitoring an animal's temperature and other vital signs. The device may be mounted in the animal's ear, under the animals skin, or in any location which can be used to generate a reliable indication of the animals temperature and other vital signs. The temperature probe for the device is inserted subcutaneously and thermally and/or electrically connected to the housing of the device. Power for the device is provided by a miniature array of solar cells, the power from the solar cells being used to drive digital circuitry which processes signals from the various probes used to gather data concerning the animal's vital signs. The size of the array is chosen to be commensurate with the number of vital signs monitored, with the amount of sunlight, density of herd, and other factors being considered to ensure sufficient power for the device.Type: GrantFiled: April 19, 2001Date of Patent: March 27, 2007Inventor: Tom Hixson

Patent number: 7180424Abstract: A computerized security system which enhances the security provided by watchdogs on a given premises by analyzing the auditory and physiological indications given by the dogs to assess the level of security at any point in time. By attaching sensors to the dogs and placing microphones in their proximity the system continuously collects information about the dogs' auditory and physiological behavior, and according to predetermined parameters it assesses the watchdogs' physiological and emotional state. Having concluded that any of the dogs sense a threat or has been neutralized in any way the system may update the state of security on the users' security terminals. The system determines between three possible security states: no alert when no irregular activity is registered, medium alert if the dogs indicate a state of moderate alertness and high incase there are indications for a definite hostile presence.Type: GrantFiled: November 5, 2003Date of Patent: February 20, 2007Assignee: Bio-SenseInventor: Zehavi Eyal

Patent number: 7180416Abstract: A method and apparatus is described for enabling a single sensor to indicate a greater quantity of information about a sensed event, or the occurrence of many different types of events. A sensor system employs a number of individual sensors with single-use indication means (such as an explosive charge). Each individual sensor is equipped with a chronometer. The sensors are programmed to transmit information through their single-use indication means at specific times with each specific time being indicative of a particular type of event or of specific information about an event. A central monitor chronologically records all sensor indications and compares indication times to a schedule of time keyed information to determine the nature of each sensor indication.Type: GrantFiled: March 2, 2005Date of Patent: February 20, 2007Assignee: The United States of America as represented by the Secretary of the NavyInventor: Charles Philip Amidon

Patent number: 7171336Abstract: A method for operating a measuring instrument is capable of performing multiple diagnostic functions. For this, a process control is provided for the execution of the diagnostic functions in a manner whereby the normal measuring operation of the measuring instrument is interrupted, a first diagnostic function is performed during that interruption, the normal measuring operation is resumed after completion of the first diagnostic function, the normal measuring operation is again interrupted, and during that later interruption of the normal measuring operation a second diagnostic function is performed. In this fashion, even numerous diagnostic functions can be easily and efficiently integrated into the operation of a measuring instrument such as a magnetoinductive flowmeter.Type: GrantFiled: November 29, 2004Date of Patent: January 30, 2007Assignee: Krohne A.G.Inventor: Helmut Brockhaus
