摘要:
A switch measurement system is disclosed for measuring characteristics of a switch while the switch is mounted to a product adjacent a product surface. The switch types may include linear, pivot and rotary types. The switch measurement system preferably has a control unit for driving a motor and receiving and storing input from a force or torque sensor. A fixturing setup preferably includes a mounting base, and three legs extending from the mounting base. Each of the legs is selectively adjustable in length and includes an end adapted for mounting against the product surface where the legs can vary the location and orientation of the mounting base relative to the product. Also, a measurement unit includes a motor fixed relative to the mounting base and includes a motor shaft extending therefrom, and a force sensor or a torque sensor, depending upon the switch measurement arrangement, interposed between the motor shaft and the switch. The motor and the sensor are in electronic communication with the control unit.

A method may be employed to assure that a switch measurement system accurately measures a torque/angular displacement profile for a rotary switch. A procedure may be employed that aligns the rotational axis of the switch with the rotational axis of the measurement unit of the switch measurement system. Also a procedure may be employed that monitors secondary forces to assure that proper alignment and calibration has been achieved.

Generally provided is a system and method that determines a force-travel profile of a shifter in a vehicle having a shifter having an associated shifter shaft for a transmission. The feel of the shifter to a user of the shifter may be improved by using present system. Additionally, accurate measurements for determining shifter forces applied to a shifter and corresponding position of the shifter are performed. In operation, the system correlates the forces applied to the shifter and associated movement of the shifter to determine an associated feel of the shifter. The system operates to equate the forces correlating to the shifter and movement of the shifter to calibrate a feel of the shifter for a user applying the force to the shifter to actuate the shifter.

A measuring system that relate to the measurement of relatively small one degree of freedom mechanisms, such as pivoting and rotary switches, is disclosed. In particular end effectors and a kit for assembling various end effector assemblies is disclosed, that allow for accurate measurement of torque versus angular displacement curves for various types of pivoting and rotary switches.

A method may be employed to assure that a switch feel measurement system accurately measures a torque/angular displacement profile for a pivot switch. A procedure may be employed that aligns the pivot axis of the switch with the rotational axis of the measurement unit of the switch measurement system.

A system and method for interactively generating a family of mesh models is provided for use in engineering analysis. The system includes a user computer system having a memory, a processor, a user input device and a display device. The system also includes a remotely located computer system having a processor, a memory, and a data storage means and in communication with the user computer system. The system further includes a computer-generated geometric mesh base model stored in the data storage means, a computer-generated mesh feature stored in the data storage means, and a new mesh model including the base mesh model with a mesh feature that is stored in the data storage means. The method includes the steps of selecting a base model from a model library maintained in the data storage means. The method also includes the steps of creating a mesh feature that is defined by a modifiable set of parameters and saving the mesh feature in a mesh feature library maintained in the data storage means. The method further includes the steps of establishing a feature matrix by the user containing instructions for selectively applying the mesh feature to the base mesh model and using the feature matrix to selectively apply the mesh feature to the base model to generate a new mesh model that is available for further analysis.

A proximity switch assembly and method are provided having wrong touch feedback. The switch includes a plurality of proximity switches each including proximity sensors providing a sense activation field. Control circuitry processes the activation field of each proximity switch to sense activation, detects an allowed activation of one of the proximity switches and further detects an attempted activation that is not allowed. The switch further includes an output coupled to a device to perform a function when an allowed activation is detected. The switch includes one or more user perceived feedback devices for generating user perceived feedback when an attempted activation that is not allowed is detected.
摘要:
A proximity switch assembly and method for detecting activation of a proximity switch assembly is provided. The assembly includes a plurality of proximity switches each having a proximity sensor providing a sense activation field and control circuitry processing the activation field of each proximity switch to sense activation. The control circuitry monitors the signal responsive to the activation field and determines a differential change in generated signal, and further generates an activation output when the differential signal exceeds a threshold. The control circuitry further distinguishes an activation from an exploration of the plurality of switches and may determine activation upon detection of a stable signal.

A vehicle door latch assembly includes a first proximity sensor on a first side of a door handle and a second proximity sensor on a second side of the door handle. The assembly also includes a latch operative to latch the door closed and to unlatch the door to allow the door to open. The assembly further includes control circuitry for activating the latch to unlatch the door based on an object such as an operator's hand sensed with both the first and second proximity sensors.
