PAGER WITH AUTOMATIC DETECTION OF INSERTION INTO HOLSTER

摘要

A holster for a radio pager contains a vibrator which can be driven by the matching radio when the pager is inserted into the holster. The pager and holster have matching electrical contacts which are made when the pager is inserted into the holster. The pager contains means to sense the connection of the vibrator motor and to convey this data to an internal microcontroller. The microcontroller has the capability to alter the mode of alert from vibrate to an alternate alert mode such as audible alert, according to the preselected choice of the user, under control of the vibrator sense signal. The vibrator sense circuit output is also used by the microcontroller to invert the display, to provide for on-belt reading of a front faced alpha-numeric pager. The use of a mechanical detection mechanism is also described for pager holster configurations in which the vibrator is contained in the pager.
