Abstract: A magnetic mount for magnetically mounting a tire pressure sensor inside a vehicle tire has a flexible frame, a sensor mount atop the frame, a first neodymium magnet under a first end of the frame, and a second neodymium magnet under an opposed second end of the frame. The frame may be H-shaped, with an elongate central member, a first member extending transversely from a first end of the central member, and a second member extending transversely from an opposed second end of the central member. A first pad is fixed under the first member, a second pad is fixed under the second member, the first magnet is fixed under the first pad, and the second magnet is fixed under the second pad. Third and fourth magnets may be fixed under the first and second pads respectively. The magnets may be circular discs having a diameter of about ¾ inch.

Abstract: A tire pressure sensor is provided having a housing, a pressure transducer within the housing electronically coupled to a transmitter, a battery within the housing connected to deliver electrical power to the pressure transducer and to the transmitter, and a pressurized compartment within the housing bounded at least partially by a flexible membrane. A first conduit extends from the pressure transducer to the compartment. An inlet port extends through the housing to allow pressurized air within the tire to contact the membrane. In particular embodiments, the pressure transducer, transmitter and battery are rubber coated and encapsulated with epoxy.

Abstract: A tire valve stem having an integral pair of O-rings over which a pressure gauge or other device can be mounted by sliding a mating collar provided on the device over the O-rings. The O-rings provide an air-tight seal against the collar, and allow the device to rotate relative to the stem, either during or after mounting, to position the device anywhere within a 360° arc around the stem. The O-rings are located on either side of an orifice which extends through the valve stem, beneath the valve. Air passes from the pressurized valve stem, through the orifice, into an air-tight region between the O-rings, valve stem and collar. A port in the collar allows air to pass through the collar from the air-tight region into the device.
