Abstract
Abstract In order to facilitate operation of a radio remote control transmitter, the transmitter components are built into the structure of a vest-like garment, and the transmitter is operated by placing a magnet on the wrist of the user adjacent one of a number of reed switches built into the vest at spaced locations so as to cause the transmitter to radiate different control signals according to the switch which is actuated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
In a radio remote control transmitter assembly, comprising an antenna and a transmitter, said transmitter comprises radio frequency means connected to the antenna to supply a radio frequency signal thereto and means to modulate the radio frequency signal supplied by the radio frequency means, said assembly further comprising switching means, a source of electrical energy, and encoder means selectively supplying any of a plurality of distinctive output signals to the modulating means in response to different conditions of said switching means, the improvement wherein the components comprised by the transmitter assembly are incorporated into the structure of a vest-type garment, and the switching means comprises a plurality of switches located on said garment at spaced locations relative by the trunk of a user, said switches being of a non-manipulatory type selectively operable to juxtaposition of a switch control means attached to a portion of the user's body movable relative to said locations on the user's trunk.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
39 words
A transmitter according to claim 1, wherein the switches are reed switches, and said switch control means is a magnet worn on said movable portion of the user's body which is juxtaposed with said locations of the user's trunk.
Claim 4
Dependent Claim
26 words
A transmitter according to claim 2, wherein the switches are located in a breast portion of the garment, and the magnet is incorporated in a wristband.
Claim 5
Dependent Claim
25 words
A transmitter according to claim 2, wherein the reed switches each comprise a pair of adjacent reed switch elements arranged with a non-zero angle therebetween.
Claim 6
Dependent Claim
17 words
A transmitter according to claim 1, wherein the antenna is a dipole arranged vertically within the garment.
Claim 7
Dependent Claim
13 words
A transmitter according to claim 5, wherein the dipole is a folded dipole.
Claim 8
Dependent Claim
21 words
A transmitter according to claim 1, wherein the transmitter, encoder means and the energy source are incorporated in flexibly encapsulated modules.
Claim 9
Dependent Claim
39 words
A transmitter according to claim 7, wherein the modules are detachably secured within the garment, and wiring connecting the modules to one another is incorporated in the garment, releasable connectors being provided to connect the modules and the wiring.
Claim 10
Dependent Claim
13 words
A transmitter according to claim 7, wherein the energy source comprises rechargeable cells.
Claim 11
Dependent Claim
36 words
A transmitter according to claim 1 wherein the output signals supplied by the encoder are digital, and the modulator means is an electronic switch which keys the radio frequency means in response to said digital signals.
Claim 12
Dependent Claim
31 words
A transmitter according to claim 10, wherein the encoder output signals consist of repeated pulse trains, the pulse trains being of different lengths according to the condition of said switching means.
