Aircraft tire pressure loop link
First Claim
1. An aircraft tire pressure loop link for electromagnetically coupling a magnetic field between an electromagnetic transceiver coil of a wheel axle and a tire pressure sensor receiver coil spaced apart from the electromagnetic transceiver coil of the wheel axle for powering a tire pressure sensor, comprising:
- a first single metal loop configured to be mounted on a carrier configured to encircle a wheel axle adjacent to the electromagnetic transceiver coil of the wheel axle;
a second single metal loop configured to be mounted adjacent to a tire pressure sensor transceiver coil; and
a pair of electrically conductive connecting arms electrically connected between said first single metal loop and said second single metal loop, said pair of electrically conductive connecting arms being configured to carry current generated in the first single metal loop from the electromagnetic transceiver coil of the wheel axle to the second single metal loop, said pair of electrically conductive connecting arms being closely spaced apart by a small gap to minimize a loop area of said pair of electrically conductive connecting arms, such that current induced in the first single metal loop travels via the pair of spaced apart electrically conductive connecting arms a distance from the electromagnetic transceiver coil of the wheel axle to the second single metal loop, to generate flux in the tire pressure sensor receiver coil for powering the tire pressure sensor, wherein no wire connections are included in the aircraft tire pressure loop link to form an electrical circuit between the electromagnetic transceiver coil of the wheel axle and the tire pressure sensor receiver coil, and said aircraft tire pressure loop link is a rigid, self-supporting structural part.

Abstract
The aircraft tire pressure loop link is formed of first and second single metal loops connected by parallel spaced apart metal shafts, and provides for coupling a magnetic field between a wheel hub coil and a tire pressure sensor coil to provide electromagnetic communication between a control unit connect to the wheel hub coil and a tire pressure sensor connected to the tire pressure sensor coil. The current induced in the first single metal loop travels the distance from the edge of the wheel axle coil to the periphery of the of the wheel rim to the second single metal loop, which generates the flux in the tire pressure sensor receiver coil necessary to power the tire pressure sensor.
