  • Secure field monitoring device for use in electronic house arrest monitoring system
    Patent number: 5146207
    Abstract: A field monitoring device (FMD) for use in an electronic house arrest monitoring (EHAM) system has an infrared (IR) communications port concealed in the back of its housing. A strain relief fixture for the power cord covers the IR port during normal FMD operation. This strain relief fixture is removable only with a special tool. The IR port includes two small holes. Inside one hole is an infrared receiver. Inside the other hole is an infrared transmitter. Data communications with the FMD is established by optically linking a matching infrared receiver included in a coupling head of an IR adapter with the infrared transmitter within the FMD; and by similarly optically linking a matching infrared transmitter with the infrared receiver within the FMD. The IR adapter interfaces with a conventional data terminal, such as a personal computer, which data terminal functions as an external programmer for the FMD.
