Abstract

A resilient housing actuated multi-level housing switch comprises a compression sensitive circuit which is actuated by compressing a resilient housing. The compression sensitive circuit comprises a compression sensing device which produces an analog signal, an A to D converter, and a microprocessor. The microprocessor is programmed with algorithms to control the power levels of communication equipment and volume levels based on signals produced by compressing the compression sensing device.

Claims

1. A resilient housing actuated multi-level switch for housing and providing switching for an electronic circuit comprises:

housing means, consisting of a resilient material, for substantially housing the electronic circuit;

compression sensing means, physically contacting at least part of the housing means, for providing a compression signal when the at least part of the housing means is sufficiently compressed; and

signal processing means, operably coupled to the compression sensing means, for comparing the compression signal with a first threshold such that when the compression signal exceeds the first threshold, the signal processing means performs at least part of a control signal algorithm.

2. In the resilient housing actuated multi-level switch of claim 1, the compression sensing means comprises a deflection measuring transducer.

3. In the resilient housing actuated multi-level switch of claim 1, the compression sensing means comprises a conductive elastomer pad and a deflection detection circuit, wherein the deflection detection circuit monitors compression of the conductive elastomer pad to produce the compression signal.

4. An improved communication radio that includes transceiving means for transceiving radio signal and a processing means, operably coupled to the transceiving means, for processing communication system information, wherein the improvement comprises:

housing means, consisting of a resilient material, for substantially housing the transceiving means;

first compression sensing means, physically contacting a first area of the housing means is sufficiently compressed; and

signal processing means, operably coupled to the compression sensing means, for comparing the first compression signal with a first threshold such that when the first compression signal exceeds the first threshold, the signal processing means performs at least part of a first control signal algorithm.

5. The improved communication radio of claim 4 further comprises a second compression sensing means, physically contacting a second area of the housing means and operably coupled to the signal conversion means, for providing a second compression signal when the second area of the housing means is sufficiently compressed.

6. In the improved communication radio of claim 5, the signal processing means compares the second compression signal with the first threshold such that when the second compression signal exceeds the first threshold, the signal processing means performs at least part of a second control signal algorithm.

7. In the improved communication radio of claim 5, producing a third multi-level signal when the first area of the housing means and the second area of the housing means are sufficiently compressed, such that both the first compression signal and the second compression signal exceeds the first threshold.
