  • Publication number: 20100320095
    Abstract: A device for monitoring chlorine in water, the device comprising a chlorine sensor adapted to measure a chlorine concentration in water; and a controller adapted to facilitate conversion between an active mode during which water analysis may be performed, and a low energy sleep mode in which the chlorine sensor is still energized but water analysis may not be performed. In sleep mode, a polarization voltage is maintained on an electrode comprised in chlorine sensor, which allows for a substantial reduction in a stabilization time required by the electrode following connection to an energy source after having been disconnected. Conversion between the active mode and the sleep mode may be according to predetermined parameter such as, for example, a predetermined time period, upon receipt of an indication from a independent timer, or by remote initiation from an external source.

  • Patent number: 7317377
    Abstract: An improved transmitting tag for enhancing the tracking and locating capability of a monitoring system and for allowing control over accessibility to particular zones and/or equipment within a restricted area. The tag is provided with a transmitter of multiple broadcasting signals for allowing periodical broadcasting of at least two signals of different strength at different time intervals and preferably of different information content. The signals carry the tag identification code and a strength identification code. The weak signals emitted by the tag can be further exploited for allowing or denying accessibility to local operating systems.

  • Patent number: 6853304
    Abstract: A monitoring device, such as a watch, for monitoring, at a remote location, movements and activities of a person, the device is worn around the wrist of the person being monitored, the device comprising, a housing, a strap connected to the housing for fastening the device around the wrist of the person being monitored, a tamper sensor for detecting tampering with or the removal of the device from the person's wrist. It further includes electronic circuitry enclosed within the housing. The circuitry includes a microprocessor and a memory device for receiving and processing data and a transmitter for periodically transmitting data to a remote location and a time display, coupled to a clock mechanism, mounted in the housing so as to be displayed at the front face of the housing.
