  • Publication number: 20100126840
    Abstract: A manually operable sensor for providing control signals to an electronic device. A fabric has a length substantially longer than its width with insulating yarns and electrically conductive yarns included therein, such that the conductive yarns define three conductive tracks running the length of the fabric. The conductive tracks are configured to interface with an electronic device at a first end and, at a second end, an active region of the fabric forms part of a sensor assembly that is receptive to a manually applied pressure. The sensor comprises first and second conductive regions to which a first and a second conductive track are connected respectively, to apply an electric potential to each conductive region. A conductive path is formed between a connected conductive track and the third conductive track of said active region when manual pressure is applied to one of the conductive regions.

  • Publication number: 20100102922
    Abstract: A manually operable position sensor is shown, for providing control signals to an electronic device, such as an audio player. A fabric ribbon (101) has a length substantially longer than its width with insulating yarns and electrically conducting yarns included therein. The conducting yarns define three conductive tracks (103, 104, 105) running the length of the fabric. The conductive tracks are configured to interface with an electronic device at a first end. At a second end, an active region of the fabric forms part of a sensor assembly that is receptive to a manually applied pressure.

  • Patent number: 7554045
    Abstract: A linear sensor (101, 201) comprising electrically conductive textile fibers (103, 105, 205, 207) and electrically insulating textile fibers (106, 208). The sensor comprises at least two conductive elements (102, 104, 204, 206) having electrically conductive textile fibers (103,105, 205, 207). The sensor also has electrically insulating textile fibers (106, 208) spaced to separate the two electrically conductive elements when no pressure is applied to said sensor, and to allow electrical conduction between the two conductive elements under the application of pressure.

  • Patent number: 7377133
    Abstract: A sensor having a three layer construction comprising a first knitted conductive textile plane, a second conductive textile plane and an intermediate separating plane penetrable by the first knitted conductive textile plane to allow the first conductive textile plane and the second conductive textile plane to make electrical contact under a mechanical interaction. The intermediate separating plane defines structural endpoints from which the first knitted conductive textile plane deforms towards the second conductive textile plane under a mechanical interaction. The first knitted conductive textile plane has conductive yarn knitted to form a repeating pattern of stitches each comprising a stitch looping portion SLP having a looping portion footprint LPF. Within the sensor, there is at least one of a plurality of described dimensional relationships between stitches of the first knitted conductive textile plane and structural endpoints of the intermediate separating plane.

  • Patent number: 6639162
    Abstract: 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.

  • Patent number: 6585162
    Abstract: The present invention relates to a data input device suitable for inputting data to electronic processing means. The data input device is configured to produce an output in response to a mechanical interaction and may be reconfigured into two operational configurations. In a first flexible configuration the device may be bent or flexed about a first axis, and in a second rigid configuration the data input device is substantially rigid such that bending or flexing of the device about the first axis is inhibited.
