1. A wrist worn communication device including means for providing an antenna integrity indication to the user, said device comprising:
- a receiver;
a wristband, including an antenna located therein coupled to said receiver, said antenna having an equivalent resistance associated therewith;
antenna sensing means coupled to said antenna for generating an antenna sensing signal based on said equivalent resistance and for deriving therefrom a closure indication signal indicating the integrity of said antenna; and
indicating means, responsive to the closure indication signal, for providing a sensible indication of the integrity of said antenna to the user.

Abstract
An apparatus for sensing the integrity of an antenna which is located within a wristband and which is coupled to a wrist worn communication device having a receiver, and an antenna sensing circuit which generates an antenna sensing signal. The antenna sensing circuit monitors the antenna sensing signal and derives an antenna integrity indication signal which indicates the integrity of the antenna. An indicating circuit is responsive to the antenna integrity indication signal and provides a sensible indication of the integrity of the antenna, such as a message indicating the antenna is open.

15. A wrist worn communication device including means for providing an antenna integrity indication to the device user, said device comprising:
-
a receiver; a wristband, including an antenna located therein coupled to said receiver; antenna sensing means for generating an antenna sensing signal which is coupled to said antenna, and for deriving therefrom a closure indication signal indicating the integrity of said antenna; power saving means, coupled to said antenna sensing means, for controlling the supply of power thereto; battery saving means, coupled to said receiver, for controlling the supply of power thereto; timing means for generating timing signals, said battery saving means being responsive to said timing means for periodically supplying power to said receiver for predetermined time intervals, and said power saving means is further responsive to said timing means for supplying power to said antenna sensing means during time intervals other than the predetermined time intervals provided for supplying power to said receiver; and indicating means, responsive to the closure indication signal, for providing a sensible indication of the integrity of said antenna to the user. - View Dependent Claims (16, 17, 18)
