Abstract
Abstract This is a selector circuit for an electronic device such as a pager that has a plurality of functions with each of the functions having a plurality of levels. First and second switches are provided for selecting the functions and levels. A controller such as a microprocessor is responsive to the first and second switches for selecting the functions and levels. The functions are selected by first actuating the first switch and then actuating the second switch while the first switch is maintained actuated. Levels of selected functions are selected by first actuating the second switch and then actuating the first switch while the second switch is maintained actuated.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
119 words
A selector for an electronic device having a plurality of functions with each function having a plurality of levels, including an ON/OFF function having an ON level corresponding to the electronic device being on and an OFF level corresponding to the electronic device being off comprising: a first switch, a second switch, and control means responsive to actuation of said first and second switches for selecting said functions and said levels, wherein said control means operatively selects functions when said first switch is actuated first and maintained actuated and said second switch is then actuated, and said control means operatively selects levels when said second switch is actuated first and maintained actuated and said first switch is then actuated.
Claim 2
Dependent Claim
119 words
A selector for an electronic device having a plurality of functions with each function having a plurality of levels, including an ON/OFF function having an ON level corresponding to the electronic device being on and an OFF level corresponding to the electronic device being off comprising: a first switch, a second switch, and control means responsive to actuation of said first and second switches for selecting said functions and said levels, wherein said control means operatively selects functions when said first switch is actuated first and maintained actuated and said second switch is then actuated, and said control means operatively selects levels when said second switch is actuated first and maintained actuated and said first switch is then actuated.
Claim 3
Dependent Claim
26 words
The selector for an electronic device as defined in claim 1, further comprising: a display means actuated by the control means for displaying selected function levels.
Claim 4
Dependent Claim
18 words
The selector for an electronic device as defined in claim 2, wherein: said control means comprises a microprocessor.
Claim 5
Dependent Claim
32 words
The selector for an electronic device as defined in claim 2, wherein: said display means includes a plurality of LED's with one of said LED's corresponding to each level of each function.
Claim 6
Dependent Claim
36 words
The selector for an electronic device as defined in claim 2, wherein: the control means is responsive to the initial actuation of at least one of said switches to display function levels that are currently selected.
Claim 7
Dependent Claim
47 words
The selector for an electronic device as defined in claim 5, wherein: the control means actuates said display means to display the currently selected level of the currently selected function at a predetermined time period after said initial actuation of said at least one of said switches.
Claim 8
Dependent Claim
27 words
The selector for an electronic device as defined in claim 5, wherein the control means is responsive to the deactuation of said switches to discontinue said display.
Claim 9
Dependent Claim
100 words
A selector for a pager having a plurality of functions including an ON/OFF function with each function having a plurality of levels, comprising: a first switch, a second switch, and control means responsive to actuation of said first and second switches for selecting said functions and said levels, wherein said control means operatively selects functions when said first switch is actuated first and maintained actuated and said second switch is then actuated, and said control means operatively selects levels when said second switch is actuated first and maintained actuated and said first switch is then actuated for controlling said pager.
Claim 10
Dependent Claim
100 words
A selector for a pager having a plurality of functions including an ON/OFF function with each function having a plurality of levels, comprising: a first switch, a second switch, and control means responsive to actuation of said first and second switches for selecting said functions and said levels, wherein said control means operatively selects functions when said first switch is actuated first and maintained actuated and said second switch is then actuated, and said control means operatively selects levels when said second switch is actuated first and maintained actuated and said first switch is then actuated for controlling said pager.
Claim 11
Dependent Claim
28 words
The selector for a pager as defined in claim 8, further comprising: a display means actuated by the control means for displaying selected function levels of said pager.
Claim 12
Dependent Claim
17 words
The selector for a pager as defined in claim 9, wherein: said control means comprises a microprocessor.
Claim 13
Dependent Claim
34 words
The selector for a pager as defined in claim 10, wherein: said display means includes a plurality of LED's with one of said LED's corresponding to each level of each function of said pager.
Claim 14
Dependent Claim
38 words
The selector for a pager as defined in claim 11, wherein: the control means is responsive to the initial actuation of at least one of said switches to display function levels of the pager that are currently selected.
Claim 15
Dependent Claim
26 words
The selector for a pager as defined in claim 12 wherein: the control means is responsive to the deactuation of said switches to discontinue said display.
Claim 16
Dependent Claim
49 words
The selector for a pager as defined in claim 12, wherein: the control means actuates said display means to display the currently selected level of the currently selected function of said pager at a predetermined time period after said initial actuation of said at least one of said switches.
Claim 17
Dependent Claim
26 words
The selector for a pager as defined in claim 14, wherein: the control means is responsive to the deactuation of said switches to discontinue said display.
