Personal security communication system
First Claim
1. A personal security communication system configured to operate as a buddy system, said system comprising:
- (a) a first portable unit for producing a first status signal and receiving a second status signal, said first portable unit transmitting said first status signal as a radio frequency carrier signal modulated with data messages, said first portable unit producing an alarm when said first status signal includes emergency alarm information, and said first portable unit also producing an alarm when said second status signal includes emergency alarm information, said first portable unit further producing an alarm when said second status signal is not received for a predetermined period of time; and
,(b) a second portable unit for producing said second status signal and receiving said first status signal, said second portable unit transmitting said second status signal as a radio frequency carrier signal modulated with data messages, said second portable unit producing an alarm when said first status signal includes emergency alarm condition information and said second portable unit also producing an alarm when said second status signal includes emergency alarm condition information, said second portable unit further producing an alarm when said first status signal is not received for a predetermined period of time.

Abstract
A personal security communication system provides an indication that a worker may be incapacitated. The system may be configured as a buddy system comprising first and second portable units (100 and 200) acting as a pair (98). Each portable unit (100 and 200) produces status information and transmits data messages containing encoded status information to the other portable unit (200 and 100). The encoded status information includes a transmitting unit indentification number and alarm condition information produced by manual alarm switches (104 and 204) and sensors (102 and 202). The sensors (1102 and 202) may include a motion sensor (45) or a motion and position sensing switch (10) that produce motion and lack-of-motion signals that are encoded in the status information. If one unit of the pair (98) produces status information containing emergency alarm information or receives a data message from the other unit of the pair (98) containing emergency alarm information or fails to receive a data message from the other unit of the pair (98) within a predetermined time limit, an alarm is produced.

13. A portable unit for use in a personal security communication system comprising:
-
a housing adapted to be worn by an individual; a signaling unit integral with said housing including a manually actuatable switch for producing an alarm signal and a motion sensor including an enclosure having an open end, a base covering said open end, a pressure sensitive electrical means on said base facing said enclosure and a mass in said enclosure adapted to move freely therein when said housing is in motion such that movement over said sensing means results in the production of a motion signal; a processing means connected to said signalling unit for receiving said alarm signal and said motion signal and for producing status information signals of said received signals including a processor alarm signal which is produced when said manual alarm signal is produced or when said motion signal indicates said housing has been motionless for a selected amount of time; a transmitting means connected to said processing means for receiving said status information signals and for transmitting said status information signals as data messages; an alarm connected to said processing means for receiving said processor alarm signal and actuatable in response to receiving said processor alarm signal; and
,a power supply coupled to supply power to said processing means, said transmitting means, and said alarm. - View Dependent Claims (14)
