Abstract

A portable radio system including dual programmable push-to-talk (PTT) switches is disclosed. One embodiment includes the PTT switches positioned so as to permit ambidextrous operation of the portable radio. Another embodiment allows a user to program the PTT switches to execute different functional tasks.

Claims

1. A ruggedized, handheld radio for bidirectional field communication, comprising:

a housing;

a single half-duplex transceiver arranged in the housing and configured to transmit and receive signals in a single communication channel over a radio network;

a first push-to-talk (PTT) switch and a second PTT switch configured to switch from a voice reception mode to a voice transmission mode, wherein the first PTT switch is located on a left side of the housing and the second PTT switch is located on a right side of the housing, and wherein the first and second PTT switches are independently operable to actuate the transmission of radio signals in the single communication channel via the single half-duplex transceiver;

a keypad mounted on the housing and including a plurality of buttons;

a memory configured to store a plurality of functional profiles associated with the PTT switches; and

a processor configured to permit user selection of one of the functional profiles and, after user selection, configure functional operation of a combination of the keypad buttons and at least one of the PTT switches according to the selected functional profile.

2. The handheld radio of claim 1, wherein each functional profile comprises a mapping of functions to buttons.

3. The handheld radio of claim 1, wherein each functional profile comprises a functional assignment for each PTT switch.

4. The handheld radio of claim 1, wherein each functional profile comprises at least one of:

a first ergonomic profile associated with a left-handed user; and

a second ergonomic profile associated with a right-handed user.

5. The handheld radio of claim 4, further comprising a third ergonomic profile configured to assign a frequency channel selection functionality to at least one of the first PTT switch and the second PTT switch.

6. The handheld radio of claim 1, wherein the handheld radio is constructed in compliance with MIL-STD-810.

7. The handheld radio of claim 1, wherein the PTT switches are arranged symmetrically about a vertical axis.

8. The handheld radio of claim 1, further comprising a field programmable gate array (FPGA), wherein the FPGA is electrically connected to the first and second PTT switches.

9. The handheld radio of claim 1, wherein each of the PTT switches have an ergonomic shape for gripping by either of a left hand and a right hand.

10. The handheld radio of claim 1, wherein the housing has an ergonomic shape for hand gripping.

11. A ruggedized, handheld radio for bidirectional field communication, comprising:

a housing;

a half-duplex transceiver arranged in the housing and configured to transmit and receive signals in half-duplex mode over a radio network;

a first push-to-talk (PTT) switch and a second PTT switch configured to switch from a voice reception mode to a voice transmission mode, wherein the first PTT switch is located on a left side of the housing and the second PTT switch is located on a right side of the housing; and

a processor and a memory configured to store a plurality of functional profiles associated with the PTT switches, wherein the processor is configured to execute software code and access the memory, wherein at least one of the functional profiles is configured to assign an unlocking function to the first PTT switch, wherein activation of the second PTT switch is configured to initiate the voice transmission mode while the first PTT switch is activated, the voice transmission mode being enabled for a time period that the second PTT switch is activated.

12. A method of operating a ruggedized, handheld radio having a processor and a memory and the processor executing a software program, the method comprising:

transmitting, via a single transceiver, signals in a single communication channel over a radio network;

receiving, via the transceiver, signals in the single communication channel over the radio network;

switching from a voice reception mode to a voice transmission mode using at least one of a first push-to-talk (PTT) switch and a second PTT switch, wherein the first PTT switch is located on a left side of the radio and the second PTT switch is located on a right side of the radio, and wherein the first and second PTT switches are independently operable to actuate the transmission of radio signals in the single communication channel via the single transceiver;

providing a keypad mounted on the housing and including a plurality of buttons;

storing in the memory a plurality of functional profiles associated with the PTT switches;

programmatically permitting user selection of one of the functional profiles; and

after user selection, programmatically configuring functional operation of a combination of the keypad buttons and at least one of the PTT switches according to the selected functional profile.

13. The method of claim 12, wherein the plurality of functional profiles comprise at least one of:

a first ergonomic profile associated with a left-handed user; and

a second ergonomic profile associated with a right-handed user.

14. The method of claim 13, further comprising a third ergonomic profile configured to assign a frequency channel selection functionality to at least one of the first PTT switch and the second PTT switch.

15. The method of claim 12, wherein the PTT switches are arranged symmetrically about a vertical axis.

16. A method of operating a ruggedized, handheld radio, comprising:

transmitting, via a single transceiver, signals in half-duplex mode over a radio network;

receiving, via the transceiver, signals in half-duplex mode over the radio network;

switching from a voice reception mode to a voice transmission mode using at least one of a first push-to-talk (PTT) switch and a second PTT switch, wherein the first PTT switch is located on a left side of the radio and the second PTT switch is located on a right side of the radio; and

assigning an unlocking function to the first PTT switch, wherein activation of the second PTT switch is configured to initiate the voice transmission mode while the first PTT switch is activated, the voice transmission mode enabled for a duration of time that the second PTT switch is activated.
