Patent number: 7173529Abstract: A system for tracking and monitoring at least one item in an environment includes at least one transmitter assigned a unique identification number for the item and attached to the item and at least one receiver for receiving a first data packet which includes the unique identification number from the transmitter. At least one node computer controls the receiver, receives a second data packet which includes said unique identification number and direction-of-travel code from the receiver, and determines a location of the item from the direction-of-travel code. A controller computer controls the node computer, receives the unique identification number and the location of the item from the node computer, and stores the unique identification number and the location of the item. A central computer facility coordinates the controller computer and collects and stores the unique identification number and the location of the item for exportation from the system.Type: GrantFiled: January 27, 2006Date of Patent: February 6, 2007Assignee: USM Systems, Ltd.Inventor: Chester T. Przygoda, Jr.

Patent number: 5438607Abstract: A programmable monitoring system for personal use in a home, medical ward, office or other localized area features a radio receiving base unit and one or more low power, radio-frequency battery-powered wireless transmitter units, each capable of transmitting uniquely encoded pulse-encoded serial digital signals at a common high frequency to the base unit. The base unit has a superregenerative receiver and a microcomputer for deciphering and validating the encoded information to ensure that the coded signal originated with a transmitter unit associated with the base unit. The portable transmitters, once activated, send a coded signal to the base unit indicative of a distress or alarm situation or a low battery condition, and which transmitter unit is transmitting. The base unit deciphers the coded signal and automatically contacts a central monitoring station via a telephone link. The base unit sends the serial number of the base unit, and the specific condition requiring attention, i.e.Type: GrantFiled: November 25, 1992Date of Patent: August 1, 1995Assignee: U.S. Monitors, Ltd.Inventors: Chester T.
