摘要:
A vehicle compass system for compensating for magnetic disturbances caused by a moveable vehicle accessory includes a magnetic field sensor and a control circuit coupled to the moveable vehicle accessory and the magnetic field sensor. The magnetic field sensor is positioned at a distance from the moveable vehicle accessory and is configured to determine an orientation of the magnetic field sensor with respect to the Earth's magnetic field and to generate magnetic field data. The control circuit is configured to receive a position signal from the moveable vehicle accessory indicating whether the moveable vehicle accessory is changing position, to receive magnetic field data from the magnetic field sensor, to compare first magnetic field data generated prior to the change in position of the moveable vehicle accessory to second magnetic field data generated after the change in position of the moveable vehicle accessory and to generate a correction value based on the comparison of the first magnetic field data and the second magnetic field data. The correction value is used to correct for the magnetic disturbance caused by the moveable vehicle accessory.
摘要:
A method for correcting a vehicle compass measurement for an interfering magnetic field generated by a vehicle accessory, where the interfering magnetic field has an intensity sufficient to cause a compass measurement error, includes monitoring the operation of the vehicle accessory and detecting a characteristic of operation of the vehicle accessory. A measurement or timing signal is then generated based on the characteristic of operation. A magnetic field for direction is measured in response to the measurement signal and an offset or correction value is determined based at least one the measured magnetic field and the characteristic of operation of the vehicle accessory.

An in-vehicle transmitter for wirelessly controlling a plurality of remote electronic systems is described. The transmitter includes a memory configured to store a plurality of wireless control code for the plurality of remote electronic systems. The plurality of wireless control code includes a first code to control the operation of a first remote electronic system and a second code different than the first code to control the operation of a second remote electronic system. The transmitter further includes a control circuit mounted to a vehicle interior element configured, in response to operator actuation of one switch, so that the transmitter provides a first wireless control signal having the first code and a second wireless control signal having the second code.

An improved drop hitch apparatus has at least one hitch plate for coupling to a portion of a hitch assembly of a trailer, a support assembly for supporting the hitch assemblies of a trailer and a towing vehicle, and a mounting assembly for mounting the apparatus to at least a portion of a hitch assembly of a towing vehicle. The drop hitch apparatus is useful as a height adjustment adapter to couple a trailer and a towing vehicle when the trailer has a hitch assembly lower than that of the towing vehicle's hitch assembly. The mounting assembly has a mounting shelf, a mounting bar, a stability member. The support assembly has an upstanding support plate and an upstanding shaft member.

A multifunction target actuator allows a bullet target to be selectively presented to a shooter such that a first side may be presented, a second side opposite the first side may be presented, and the target may be oriented so as not to be presented to the shooter. The actuator allows for quick and accurate movement of the target.

A method includes electromechanical engraving a three-dimensional molding pattern (N) in a rigid surface. The rigid surface is configured to micro replicate according to the molding pattern (N). The rigid surface may be a pattern roller. The molding pattern may be for micro replication of optical elements (5) of a light redirecting film (2).
