Patent ID: 7421902

Claim:
A method of producing a circuit carrier for mounting components of a pressure sensing circuit, the method comprising: forming on a substrate a circuit portion and an antenna portion, wherein forming said antenna portion comprises forming a radio frequency antenna on said antenna portion; and wherein forming said circuit portion comprises: causing at least one power supply mount for a power supply for the pressure sensing circuit to be formed at a side of said substrate such that the power supply projects outwardly from said substrate; causing a pressure sensor mount to be formed on said substrate such that when a pressure sensor is mounted to said mount a flat surface about a sensor opening of the pressure sensor is generally parallel and spaced apart from a first surface of said substrate and is adjacent the power supply; causing ancillary component mounts to be formed in said circuit portion, said ancillary component mounts being operable to facilitate mounting of ancillary components for effecting a transmitter function; and causing circuit interconnections between said at least one power supply mount, said pressure sensor mount and said ancillary component mounts and said antenna to be formed on said substrate such that a pressure sensor mounted to said pressure sensor mount and ancillary components mounted to said ancillary component mounts and are operable to receive power from a power supply mounted to said power supply mount and such that when the pressure sensor and ancillary components receive power from the power supply the transmitter function is effected, the transmitter function being operable to produce a transmittable signal in response to a pressure signal received from the pressure sensor, the transmittable signal being operable to be radiated by said antenna, for wireless reception by a remote receiver.
