Publication number: 20100320095Abstract: 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.Type: ApplicationFiled: October 27, 2008Publication date: December 23, 2010Inventors: Natan Galperin, Tzur Ben-David

Patent number: 7317377Abstract: 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.Type: GrantFiled: September 25, 2001Date of Patent: January 8, 2008Assignee: DMATEK, Ltd.Inventors: Natan Galperin, Lev Rusman, Yoav Reisman, Guy Greitser, Gil Gemer
