A tire pressure monitoring system is configured to communicate with a tire pressure sensor and has an antenna assembly and a transmitter. The antenna assembly has a transmitting and a cancelling antenna. The transmitting antenna has a wire loop defined by a plurality of coils with a first terminal and a second terminal. The cancelling antenna has a wire loop defined by a plurality of coils with a first terminal and a second terminal. The arrangement of the transmitting antenna and the cancelling antenna defines a proximal zone wherein a field from the transmitting antenna is configured to be sufficient to actuate the tire pressure monitor, while beyond the proximal zone, a field from the cancelling antenna cancels the field from the transmitting antenna. The transmitter is coupled to the transmitting antenna, and the cancelling antenna. An antenna and methods are likewise disclosed.

This apparatus relates to a portable, fold-up hoist for attachment to a vehicle via a receiver hitch. The hoist has a tongue member for insertion into and securement by the hitch. Pivotally connected to the tongue member is a telescoping vertical support member. On the upper end of the vertical support member is a boom arm, which is both pivotally and swivelably connected to the vertical support member. Thus, the boom arm may be supported perpendicular to the vertical member and swivel around the vertical support member, for example, to move directly above the tongue and to move to be parallel but opposing the tongue. The boom arm may pivot down to be near and generally parallel to the vertical support member for storage. The vertical support member is pivotal on its proximal end from a first (storage) position generally parallel to the tongue member to a second (use) position generally perpendicular to the tongue member. A winch at various positions on the hoist, for example, and pulleys may be provided on the tongue, vertical support member or the horizontal boom arm for receiving a cable or line.
