Abstract:
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.
Abstract:
An embodiment of the invention relates to an operating device (11) for a ceramic hob (131), wherein a cover (15, 115) is provided with control panels (13, 113). Below these panels, FSR sensors (21) are positioned. When a control panel (13) is pushed down by a process of operation, the FSR sensor (121) will detect this operation and a signal can be interpreted as a process of operation as a result of the change in electric resistance.
Abstract:
In a data-input device (4) an actuator element (6) that can be manually actuated, and a sensor (9) mechanically coupled to the actuator element (6). The sensor (9) is formed in a body (10) of semiconductor material housing a first sensitive element (11), which detects the actuation of the actuator element (6) and generates electrical control signals. The first sensitive element (11) is a microelectromechanical pressure sensor, formed by: a cavity (24) made within the body (10); a diaphragm (25) made in a surface portion of the body (10) and suspended above the cavity (24); and piezoresistive transducer elements (26) integrated in peripheral surface portions of the diaphragm (25) in order to detect its deformations upon actuation of the actuator element (6).

The input device of the invention includes: a lower sheet (11) on which four resistors (16-19) are formed in a manner that each two of them with a center put in between are placed to face each other circumferentially with a spacing of about 90°; an upper sheet (12) overlying the lower sheet with a spacing, on which conductors (20- 23) are formed to face the respective resistors; elastic bodies (25) disposed over the upper sheet to face the respective conductors; and an operation member (26) to retain upper parts of the elastic bodies. And, when the operation member is pressed downward, the elastic bodies are brought into contact with the resistors with interventions of the conductors on the upper sheet.

Abstract:
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.

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.
Abstract:
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.
