Abstract
Abstract A subscriber terminal (104) operable in a wireless communications system (100) having an infrastructure (111) and arranged and constructed to provide data communications between the infrastructure and the subscriber terminal, includes a radio frequency receiver (201) arranged to receive communications from the infrastructure during an active time period (303); and a portable computing device (105) operatively coupled to the radio frequency transceiver and arranged to forego a desense generating activity during the active period. A corresponding method includes determining an active time period for the RF receiver (403); directing the computer to forego desense generating activities (405) during the active time period; and activating the RF receiver (407) during the active time period.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
123 words
In a wireless communications system having an infrastructure and subscriber terminals and arranged and constructed to provide data communications between the infrastructure and the subscriber terminals, the subscriber terminals including a computer operatively coupled to a radio frequency (RF) receiver, a method of avoiding desensitization of the radio frequency receiver by the computer including the steps of: determining an active time period for the RF receiver, where the active time period is predetermined according to a communications protocol; directing the computer to forego desense generating activities during at least a portion of said active time period, including disabling a display for the computer during at least said portion of said active time period; and activating said RF receiver during said active time period.
Claim 2
Dependent Claim
123 words
In a wireless communications system having an infrastructure and subscriber terminals and arranged and constructed to provide data communications between the infrastructure and the subscriber terminals, the subscriber terminals including a computer operatively coupled to a radio frequency (RF) receiver, a method of avoiding desensitization of the radio frequency receiver by the computer including the steps of: determining an active time period for the RF receiver, where the active time period is predetermined according to a communications protocol; directing the computer to forego desense generating activities during at least a portion of said active time period, including disabling a display for the computer during at least said portion of said active time period; and activating said RF receiver during said active time period.
Claim 3
Dependent Claim
18 words
The method of claim 1 further including a step of reactivating the computer after said active time period.
Claim 4
Dependent Claim
24 words
The method of claim 2 wherein said step of reactivating said computer occurs during a subsequently determined inactive portion of said active time period.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein said step of determining an active time period includes utilizing an active portion of a power save protocol.
Claim 6
Dependent Claim
27 words
The method of claim 1 wherein said step of determining an active time period includes utilizing a prescribed time period after a transmission from the subscriber terminal.
Claim 7
Dependent Claim
25 words
The method of claim 1 wherein said step of directing the computer to forego desense generating activities includes disabling a power supply for the computer.
Claim 8
Dependent Claim
28 words
The method of claim 1 wherein said step of disabling a display for the computer includes stopping sending of switching commands to a display driver for the display.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
90 words
A subscriber terminal operable in a wireless communications system having an infrastructure and arranged and constructed to provide data communications between the infrastructure and the subscriber terminal, the subscriber terminal comprising in combination: a radio frequency receiver arranged to receive communications from the infrastructure during an active time period that is predetermined according to a communications protocol; a display; and a portable computing device operatively coupled to the radio frequency receiver and the display and arranged to disable the display during at least a portion of said active time period.
Claim 11
Dependent Claim
90 words
A subscriber terminal operable in a wireless communications system having an infrastructure and arranged and constructed to provide data communications between the infrastructure and the subscriber terminal, the subscriber terminal comprising in combination: a radio frequency receiver arranged to receive communications from the infrastructure during an active time period that is predetermined according to a communications protocol; a display; and a portable computing device operatively coupled to the radio frequency receiver and the display and arranged to disable the display during at least a portion of said active time period.
Claim 12
Dependent Claim
21 words
The subscriber terminal of claim 9 wherein said radio frequency receiver further includes a controller for determining said active time period.
Claim 13
Dependent Claim
25 words
The subscriber terminal of claim 10 wherein said controller further includes an active portion of a power save protocol in determining an active time period.
Claim 14
Dependent Claim
28 words
The subscriber terminal of claim 10 wherein said controller further includes a prescribed time period after a transmission from the subscriber terminal in determining an active time period.
Claim 15
Dependent Claim
24 words
The subscriber terminal of claim 10 wherein said controller further provides an active signal to said portable computing device during said active time period.
Claim 16
Dependent Claim
20 words
The subscriber terminal of claim 9 wherein said portable computing device disables the display in response to said active signal.
Claim 17
Dependent Claim
25 words
The subscriber terminal of claim 14 wherein said portable computing device is deactivated during said active time period and reactivated after said active time period.
Claim 18
Dependent Claim
37 words
The subscriber terminal of claim 15 wherein said portable computing device is deactivated during a subsequently determined active portion of said active time period and reactivated after said subsequently determined active portion of said active time period.
