Abstract
Abstract A communication apparatus (100) includes an automatically configured multimode talk switch (154). The communication apparatus (100) can be operated in a simplex communication mode, for receive or transmit operations, and a duplex communication mode, for simultaneous receive and transmit operations. The switch (154) is automatically configured as a push-to-talk momentary switch when the communication apparatus operates in the simplex communication mode (232, 235), and automatically configured as an on-hook/off-hook switch, when the communication apparatus operates in the duplex communication mode (242,245).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
91 words
A communication apparatus, comprising: a two-way communication device, the communication device being selectively operable in a duplex communication mode enabling simultaneous receive and transmit operations, and a simplex communication mode enabling receive or transmit operations at a particular time; and an audio accessory coupled to the communication device, the audio accessory comprising a control switch that is automatically configured as a push-to-talk momentary switch when the communication device operates in the simplex communication mode, and automatically configured as an on-hook/off-hook switch, when the communication device operates in the duplex communication mode.
Claim 2
Dependent Claim
91 words
A communication apparatus, comprising: a two-way communication device, the communication device being selectively operable in a duplex communication mode enabling simultaneous receive and transmit operations, and a simplex communication mode enabling receive or transmit operations at a particular time; and an audio accessory coupled to the communication device, the audio accessory comprising a control switch that is automatically configured as a push-to-talk momentary switch when the communication device operates in the simplex communication mode, and automatically configured as an on-hook/off-hook switch, when the communication device operates in the duplex communication mode.
Claim 3
Dependent Claim
22 words
The communication apparatus of claim 1, wherein audio accessory comprises a microphone, and the control switch selectively causes activation of the microphone.
Claim 4
Dependent Claim
13 words
The communication apparatus of claim 2, wherein the audio accessory comprises a speaker.
Claim 5
Dependent Claim
22 words
The communication apparatus of claim 2, wherein the audio accessory comprises a headset, and the control switch is coupled to the headset.
Claim 6
Dependent Claim
28 words
The communication apparatus of claim 1, wherein the simplex communication mode corresponds to a radio dispatch mode, and the duplex communication mode corresponds to a telephone interconnect mode.
Claim 7
Dependent Claim
84 words
A communication apparatus, comprising: a transceiver alternatively operable in first and second communication modes; and a momentary switch coupled to the transceiver, the switch having first and second configuration modes corresponding to the first and second communication modes, respectively; wherein, in the first configuration mode, the switch enables continuous transmission by the transceiver while the switch is continuously engaged, and in the second configuration mode, the switch enables continuous transmission upon a momentary engagement, and disables continuous transmission upon a subsequent successive momentary engagement.
Claim 8
Dependent Claim
84 words
A communication apparatus, comprising: a transceiver alternatively operable in first and second communication modes; and a momentary switch coupled to the transceiver, the switch having first and second configuration modes corresponding to the first and second communication modes, respectively; wherein, in the first configuration mode, the switch enables continuous transmission by the transceiver while the switch is continuously engaged, and in the second configuration mode, the switch enables continuous transmission upon a momentary engagement, and disables continuous transmission upon a subsequent successive momentary engagement.
Claim 9
Dependent Claim
23 words
The communication apparatus of claim 6, further comprising an audio accessory attached to the transceiver, wherein the audio accessory comprises the momentary switch.
Claim 10
Dependent Claim
29 words
The communication apparatus of claim 6, wherein the first communication mode corresponds to a simplex dispatch mode, and the second communication mode corresponds to a duplex telephone interconnect mode.
Claim 11
Dependent Claim
32 words
The communication apparatus of claim 6, wherein the first configuration mode configures the momentary switch as a push-to-talk switch, and the second configuration mode configures the momentary switch as an on-hook/off-hook switch.
Claim 12
Dependent Claim
80 words
In a radio telephone device having a simplex communication mode, and a duplex communication mode, and having an operator actuated control switch, a method comprising the steps of: operating the radio telephone device in one of the simplex communication mode, and the duplex communication mode; automatically configuring the switch as a momentary talk switch when operating in the simplex communication mode; and automatically configuring the momentary talk switch as an on/off hook switch when operating in the duplex communication mode.
Claim 13
Dependent Claim
80 words
In a radio telephone device having a simplex communication mode, and a duplex communication mode, and having an operator actuated control switch, a method comprising the steps of: operating the radio telephone device in one of the simplex communication mode, and the duplex communication mode; automatically configuring the switch as a momentary talk switch when operating in the simplex communication mode; and automatically configuring the momentary talk switch as an on/off hook switch when operating in the duplex communication mode.
Claim 14
Dependent Claim
38 words
The method of claim 10, wherein the step of operating the radio telephone device, comprises the steps of: monitoring to detect an incoming telephone call; and selecting the duplex communication mode upon detection of the incoming telephone call.
Claim 15
Dependent Claim
38 words
The method of claim 11, wherein the step of operating the radio telephone device, comprises the steps of: monitoring to detect an incoming dispatch call; and selecting the simplex communication mode upon detection of the incoming dispatch call.
Claim 16
Dependent Claim
36 words
The communication apparatus of claim 3, wherein the control switch causes activation and deactivation of the speaker and microphone, depending on whether the communication device operates in the simplex communication mode or the duplex communication mode.
Claim 17
Dependent Claim
19 words
The communication apparatus of claim 6, wherein the transceiver comprises communication circuitry for communicating over a radio frequency channel.
Claim 18
Dependent Claim
