Abstract
A portable wireless user communication device is wirelessly coupled to a second device over a monitored link. If the link is lost or endangered, then a user alarm is activated at the portable wireless user device and/or at the second device to which it is linked (which may also be a portable electronic device). The type of monitoring and/or the type of alarming may be user selectable.
Claims21
A portable wireless user communication device capable of being wirelessly coupled to a second device via a wireless link which provides a detectable characteristic while the link is operatively established, said portable wireless user communication device comprising:
- a wireless link monitor which detects said characteristic;
- and
- a user alarm which signals a user of said communication device in response to an output of the wireless link monitor representing impairment of the wireless link.
A method for operating a portable wireless user communication device capable of being wirelessly coupled to a second device via a wireless link which provides a detectable characteristic while the link is operatively established, said method comprising:
- monitoring a wireless link by detecting said characteristic;
- and
- issuing a user alarm signaling a user of said communication device in response to an output of the wireless link monitor representing impairment of the wireless link.
A digital computer program storage medium storing a computer program for controlling, when executed, the method of operation of a portable wireless user communication device capable of being wirelessly coupled to a second device via a wireless link which provides a detectable characteristic while the link is operatively established, said method comprising:
- monitoring a wireless link by detecting said characteristic;
- and
- issuing a user alarm signaling a user of said communication device in response to an output of the wireless link monitor representing impairment of the wireless link.
A pair of portable devices which are capable of being wirelessly interconnected to each other via an RF link which includes a detectable characteristic, at least one of said devices comprising:
- a monitor which detects the absence or impairment of said detectable characteristic;
- and
- a user alarm which signals a user of the device of such detected absence or impairment of said detectable characteristic.
