Abstract: Various embodiments of the present invention provide systems and method for behavior determination. As an example, a system for behavior determination is disclosed that includes: a first monitoring device, a second monitoring device, and a monitoring system. The monitoring system is operable to: receive information from the first monitoring device; receive information from the second monitoring device; identify at least a first zone around the first monitoring device; identify at least a second zone around the second monitoring device; and characterize an intersection of the first zone and the second zone.

Abstract: Various embodiments of the present invention provide systems and method for collision avoidance. As an example, a system for collision avoidance is disclosed that includes: a first monitoring device, a second monitoring device, and a monitoring system. The monitoring system is operable to: receive information from the first monitoring device and the second monitoring device, identify a first zone around the first monitoring device and a second zone around the second monitoring device, and identify an intersection of the first zone and the second zone.

Abstract: Various embodiments of the present invention provide systems and method for adaptive monitoring of physical movement. As one example, a method for adaptive initialization of a monitoring system is discussed. The method includes associating a monitor device with a monitor target; receiving information indicating movement of the monitor target from the monitor device; plotting or defining one or more paths corresponding to the movement of the monitor target during a learning period; and based at least in part on the one or more paths, identifying one or more exclusion zones where movement of the monitor target is restricted.

Abstract: Various embodiments of the present invention provide tracking devices and systems, and methods for using such. As one example, a method for locating a individual monitoring device is disclosed that includes determining a discard status of an individual monitoring device, identifying a location of the individual monitoring device, uploading the location of the individual monitoring device to a monitoring system via a wireless communication link, entering a low power state of the individual monitoring device, receiving a wake-up signal from a mobile transmitter, and transmitting a human identifiable location signal.

Abstract: An EHAM system consists of a central monitoring system (CMS), a field monitoring device (FMD), an electronic detection circuit that generates a detection signal upon the occurrence of a predetermined event, e.g., the absence of the monitored individual from a monitoring location, and a communications network. The communications network consists of at least one communications link wherein a fee-based communications mode may be used. The CMS is installed at a central monitoring location, the FMD is installed at the monitoring location, and the electronic detection circuit is attached or otherwise coupled to the individual to be monitored at the monitoring location. The occurrence or non-occurrence of the predetermined event is detected during a prescribed reporting time period. Regular or random communications are established between the FMD and CMS during the reporting time period to inform the CMS about the occurrence or non-occurrence of the predetermined event.

Abstract: A supervisory system and method automatically tracks and reports the status, e.g., current address, employer, telephone number, etc., of a group of enrollees, and automatically collects a fee for such service. Each enrollee "reports in" to a host CPU of the system in accordance with a specific contact schedule, e.g., once a month, through a fee-based telephone network that automatically charges a prescribed toll fee to the originating telephone number whenever telephone contact remains established for more than a preamble time period. The host CPU, using individual calling line identification (ICLID) information included in the incoming telephone call, identifies the telephone number of the incoming call and determines if it belongs to an enrollee of the system. If not, the incoming call is disconnected before the preamble time period expires, thereby preventing the incoming caller from being charged the toll fee.
