Patent number: 7489249Abstract: An apparatus and method for the determination of the attitude of a remotely monitored device attached or non-attached to the body of a remotely monitored person is disclosed. The device attitude is determined by two tilt-over switches having pre-defined operating angles that operate in combination. Periodically, indication concerning the number degrees of inclination measured by two tilt-over switches is obtained and a device attitude monitoring calculation is performed based on the indications.Type: GrantFiled: August 11, 2005Date of Patent: February 10, 2009Assignee: DMATEK Ltd.Inventors: Gil Better, Gil Gemer, Guy Greitser, Dan Zeeli

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
