Abstract: 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.

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.

Abstract: A tag and method for use with a monitoring system, the tag having straps for attaching the tag to the limb of a person, a motion sensor for determining the motion of the person wearing the tag and a second sensor for detecting that the tag was tampered with, the information received from the tag can be identified as tamper alarms.

Abstract: A monitoring and tracking system comprising a plurality of transmitting tags attachable to a plurality of monitored individuals, a plurality of monitoring devices and a central monitoring server. The transmitting tags, each having a unique code, periodically transmit data carrying signals, the signals are received by any of the local monitoring devices when a tag is within a reception range of a local monitoring device for allowing tracking the monitored individuals.

Abstract: A receiving unit and method for determining the distance of an object from a receiving unit in a monitoring system, the receiving unit receives transmitted signals, the receiving unit comprises an attenuating unit for attenuating the transmitted signals by a controlled factor; a receiver for receiving and processing the transmitted signals into readable data; a microcontroller for controlling the operation of the local monitoring unit; and an electronic circuitry for calculating the received strength signal indication, whereby the distance of an object from the receiving unit can be determined.

Abstract: An electronic monitoring system includes an electronic monitoring device having straps for attaching the device to a limb of a subject for monitoring, at a remote location, movements and/or other activities of the subject; a closure member to be applied to the ends of the straps to secure them together according to the size of the subject's limb to be enclosed; and a manual resetting device having electrical terminals adapted to be brought into electrical communication with electrical terminals on the strap ends when the closure member is removed for resetting the electronic monitoring device.

Abstract: An electronic monitoring device to be attached to a subject for monitoring, at a remote location, movement and/or other activities of the subject, includes a closure member incorporating an identification tag having a unique identification number stored therein. The monitoring device further includes an electronic data processor programmed to read and store the identification number of the electronic tag when the closure member is applied, and periodically thereafter, to make a determination of whether a closure member is currently attached to the subject having an identification number matching the stored identification number, and to transmit to the remote location an identification signal corresponding to such determination.
