A system and method for manipulating image data is disclosed. Generally, the system and method identifies useful grey-levels within an input image. The image is then scaled based upon the identified useful grey-levels.

Signal intensity range transformation apparatus and method

A recognition switch assembly ( ) has a movable contact assembly ( ) mounted on an actuator ( ) mounted for sliding movement along a longitudinal direction ( ) in a housing ( ) with a stationary contact board ( ) mounted on the housing over the movable contact assembly ( ). The actuator is formed with a laterally deflectable beam ( ) on one side of the actuator having a protrusion ( ) which cooperates with space protrusions ( ) on the opposed side for sliding engagement with opposed sidewalls ( ) of the housing. A pair of vertically deflectable beams ( ) having a protrusion ( ) slidingly engage platform surfaces ( ). When mounted in the housing, the beams are deformed to eliminate clearances between the actuator ( ) and the housing ( ) in both the vertical and lateral directions resulting in an improved, vibration independent, electrical output signal of the switch assembly.

Gear recognition switch system

An internal vehicular transmission range switch (10) has a movable contact support (20) which slides along a straight path in a recess formed between a housing having a base member (12) and cover (14) between first and second extremities in dependence upon the movement of the manual valve (4) to which it is coupled by an arm (18) extending from the support through a slot (16) formed in the housing. An elongated slider having a lower (20e) and upper (20d) blade portions received in respective channels (12a, 14a) formed in the housing integrally attached to the movable contact support blocks ingress of contaminant particles into the recess while permitting fluid flow into and out of the recess. A second embodiment (10') has a generally U-shaped member (18') having one leg (18a') attached to the movable contact support and extending through an O-ring (24) in an end wall of the housing and a manual valve coupling arm (18c') formed at the distal end of a second leg (18b'). A third embodiment has an endless track (26) in which an elongated, flexible band (28) having opposite ends attached to the movable contact support (20) on opposite sides of manual valve coupling arm (18) blocks entry of contaminant particles through slot (16') in the housing through which arm (18) extends.

Internal transmission range switch system

A pressure sensor for providing an electrical signal corresponding to pressure in a cylinder of an automotive engine has a rigid load-spreading element rigidly secured to a first surface of a ceramic piezoelectric body by a rigid bonding material precisely conformed to the first surface to be in substantially uniform load-transferring relation to all parts of the first body surface, has a rigid support member rigidly secured to a parallel, opposite surface of the ceramic piezoelectric body by a rigid bonding material precisely conformed to the opposite surface to be in substantially uniform load-transferring relation to all parts of the opposite body surface to form a piezoelectric unit, and has a peripheral part of the rigid support member precisely mounted with an interference fit in a bore in a metal component of a mounting structure so that the body of piezoelectric material and the load-spreading element extend in cantilever relation at a precisely determined location to be engaged by force applied through a diaphragm in response to an applied pressure to provide an electrical signal precisely corresponding to the pressure.
