Abstract
Abstract A combined radio pager/analog timepiece that may be worn on the wrist of the user is described. The device includes a stepping motor to periodically advance the second hand of the watch portion. The voltage pulse device signals to the timepiece are effectively inhibited during those intervals when the paging receiver is activated. Receiver activation occurs so as to monitor its communication channel or actually process an intended message if its unique address has been received and detected. These inhibited, i.e. delayed, voltage device pulses are later applied to the stepping motor on an accelerated basis to bring the timepiece to current time status.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
158 words
In a combination radio pager/time piece device with moving hour, minute and second hands controlled by a stepping motor, an arrangement for preventing pager receiver desensitization during stepping motor operation, comprising in combination: first means for momentarily activating the paging receiver at substantially regular intervals to determine if its address has been transmitted and for processing paging messages when its address has been received and detected; second means for supplying voltage pulses to the time piece stepping motor at regular intervals to advance the second hand; and third means coupled to said second means and responsive to said first means for inhibiting said voltage pulses to the stepping motor during those intervals when the paging receiver has been activated, said last named means further including fourth means for subsequently applying said inhibited voltage pulses on a sequential but accelerated basis upon deactivation of the paging receiver so as to bring the time piece up to current time status.
Claim 2
Dependent Claim
158 words

Claim 3
Dependent Claim
44 words
An arrangement for preventing receiver desensitization in accordance with calim 1 wherein said first means said second means for periodically activating the paging receiver and for supplying voltage pulse drive signal to the stepping motor comprises a data processor controlled by a reference oscillator.
Claim 4
Dependent Claim
44 words
An arrangement for preventing receiver desensitization in accordance with calim 1 wherein said first means said second means for periodically activating the paging receiver and for supplying voltage pulse drive signal to the stepping motor comprises a data processor controlled by a reference oscillator.
Claim 5
Dependent Claim
33 words
An arrangement for preventing receiver desensitization in accordance with claim 2 wherein the data processor includes a microprocessor for inhibiting and later applying said delayed voltage pulse drive signals to the stepping motor.
Claim 6
Dependent Claim
42 words
An arrangement for preventing receiver desensitization in accordance with claim 1 wherein the voltage pulses initially applied to the stepping motor are on a one second basis and said delayed pulses are applied on an accelerated basis of less than one second.
Claim 7
Dependent Claim
49 words
An arrangement for preventing receiver desensitization in accordance with claim 1 wherein said third means for inhibiting said voltage pulses includes means for inhibiting such pulses during those intervals when the paging receiver is activated as well as an additional interval T1 during which the receiver may become activated.
Claim 8
Dependent Claim
30 words
An arrangement for preventing receiver desensitization in accordance with claim 5 wherein the additional interval T1 corresponds substantially to the time period of a stepping motor voltage pulse drive signal.
Claim 9
Independent Claim
129 words
A method of preventing receiver desensitization in a combination radio pager-analog time piece device when operating the associated stepping motor during intervals when the paging receiver is also activated, comprising the steps of: momentarily activating the paging receiver at substantially regular intervals to determine if its address has been transmitted and for processing paging messages when its address has been received and detected; supplying voltage pulses to the time piece stepping motor at regular intervals to advance its second hand; inhibiting said voltage pulses to the stepping motor during those intervals when the paging receiver has been activated; and subsequently applying said inhibited voltage pulses on a sequential but accelerated basis upon deactivation of the paging receiver so as to bring the time piece up to current time status.
Claim 10
Independent Claim
129 words
A method of preventing receiver desensitization in a combination radio pager-analog time piece device when operating the associated stepping motor during intervals when the paging receiver is also activated, comprising the steps of: momentarily activating the paging receiver at substantially regular intervals to determine if its address has been transmitted and for processing paging messages when its address has been received and detected; supplying voltage pulses to the time piece stepping motor at regular intervals to advance its second hand; inhibiting said voltage pulses to the stepping motor during those intervals when the paging receiver has been activated; and subsequently applying said inhibited voltage pulses on a sequential but accelerated basis upon deactivation of the paging receiver so as to bring the time piece up to current time status.
Claim 11
Dependent Claim
43 words
A method of preventing receiver desensitization in accordance with claim 7 wherein said steps of periodically activating the paging receiver and for supplying voltage pulse drive signal to the stepping motor are effected by an included data processor controlled by a reference oscillator.
Claim 12
Dependent Claim
33 words
A method of preventing receiver desensitization in accordance with claim 8 wherein the data processor includes a microprocessor for inhibiting and later applying said delayed voltage pulse drive signals to the stepping motor.
Claim 13
Dependent Claim
