摘要:
The present invention relates to a detector constructed from electrically conducting fabric and configured to present a varying electrical characteristic in response to a mechanical interaction. The detector comprises a first conducting layer which is displaced from a second conducting layer such that conduction between the layers results when the layers are mechanically forced together. In addition, the first of the layers has a plurality of lengths of conductive yarn and a plurality of lengths of non-conductive yarn machined therein, such that at least one length of conductive yarn is electrically isolated from another of the lengths of conductive yarn and the conducting yarns in the first of the layers are electrically grouped to define a plurality of identifiable rows. Each identifiable row has a respective electrical conductor; and define specific regions of the detector.

The cost and complexity of an electronic pressure sensitive transducer (20) are decreased by constructing such a transducer directly on a printed circuit board (22) containing support electronics. Conductive traces (24) are formed on the printed circuit board (22) to define a contact area (26). A flexible substrate (28) having an inner surface is positioned over the contact area (26). An adhesive spacer (34), substantially surrounding the contact area (26), attaches the flexible substrate to the printed circuit board (22). At least one resistive layer (32) is deposited on the flexible substrate (28) inner surface. In use, the resistive layer (32) contacts at least two conductive traces (24) in response to pressure applied to the flexible substrate to produce an electrical signal indicative of applied pressure.

A tactile feedback simulating fabrication for use with an input device provides flexible mouldings (801) locatable above detection positions. Flexible mouldings (801) provide tactile feedback simulating a key-press. Each of the mouldings (801) defines a top portion (802) and a flexible side wall (803). A flexible fabric layer (804) is attached to the flexible mouldings thereby significantly enhancing the durability of these mouldings.

It is an object of the present invention to allow both a digital operation and an analog operation by using pressing operation continuously. An operating device has detecting elements (e.g., pressure-sensitive elements (12)) for outputting analog signals according to pressing operations of operators (11), and is configured such that analog signals output from the detecting elements are subjected to level dividing by a level dividing unit (15) and converted into multi-bit digital signals corresponding to the output levels thereof by an A/D converting unit (16), and is also configured so as to output single-bit digital signals according to change in analog signals output from the detecting element. A switching unit (18) output one or the other of the multi-bit digital signals and single-bit digital signals.

A vehicle interior trim panel electrical switch assembly (10) includes a switch panel portion (16) with a continuous outer surface (18). Force sensitive resistor switches (20a-20g) are supported on the switch panel portion (16) and are secured to the inner surface of a skin cover having a continuous outer surface (18) and forming the outer layer of a soft feel composite. The force sensitive resistor switches are embedded in the soft feel composite either as being cast in a layer of flexible foam or being applied within preformed openings in a layer of flexible foam in certain embodiments in which case they are associated with a circuit module (34) that negates preloading effects due to thermal expansion caused by changes in ambient conditions. In a preferred embodiment the correction occurs due to a circuit configuration that corrects for such preloading effects on a deflection rate basis. The circuit module (34) for each switch (20a-20g) may also include a relay in high power applications.

摘要:
A sensor array, usually a sensor matrix for sensing pressure, comprising a grid of conductors in a woven fabric, the row conductors (10) crossing over the column conductors (12) to form a matrix array of crossover points (15). The rows are separated from the column by individually coating the conductors of one or both series with an electrically partially resistive fibrous material (14), so that when the conductors at any crossover point in the array are passed closer together, the resistance between the two conductors at that crossover point decreases. By connecting the conductors to suitable electrical circuitry, the force applied at any crossover point and the location of that crossover point within the array can be determined.
