Publication number: 20070289859Abstract: A linear sensor (101, 201) comprising electrically conductive textile fibres (103, 105, 205, 207) and electrically insulating textile fibres (106, 208). The sensor comprises at least two conductive elements (102, 104, 204, 206) having electrically conductive textile fibres (103,105, 205, 207). The sensor also has electrically insulating textile fibres (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.Type: ApplicationFiled: February 2, 2005Publication date: December 20, 2007Applicant: ELEKSEN LIMITEDInventors: David Sandbach, Stuart Walkington

Publication number: 20070141939Abstract: 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.Type: ApplicationFiled: March 17, 2005Publication date: June 21, 2007Applicant: Eleksen LimitedInventors: David Sandbach, John Burkitt, Stuart Walkington, Phillipe Crispin

Publication number: 20060107762Abstract: A manually deformable input device responsive to manually applied pressure. The input device comprises a deformable electroconductive material (602) configured to exhibit changes in conductance (resistance) in response to being stretched or compressed, from which an extent of manually applied pressure can be determined. An electrical interface device (604) is configured to supply electrical current through the electroconductive material (602) via a first terminal (605) and a second terminal (606), and the input device further comprises a third terminal (607) connected at a position intermediate the first and second terminals. The electrical interface device (604) is configured to receive a voltage from the third terminal (607), which is representative of a proportion of voltage drop across the electroconductive material (602). The input device operates as a potential divider sensitive to manual operation irrespective of the absolute conductance (resistance) of the electroconductive material (602).Type: ApplicationFiled: January 9, 2004Publication date: May 25, 2006Inventors: David Sandbach, Stuart Walkington, Kirsti Lehtimaki

Publication number: 20050238405Abstract: A flexible foldable keyboard apparatus includes a flexible foldable keyboard (101) having a key defining plane (102), an interface device and phone supporting device (103). The phone supporting device (103) is arranged to unfold from a storage configuration, in which the phone supporting device (103) is folded onto the key defining plane (102) to allow the key defining plane (102) to be wrapped around the phone supporting device (103), to present a telephone supporting configuration, in which the phone supporting device (103) is configured to receive a mobile telephone (401). The phone supporting device (103) is configured to support a mobile telephone (401) in an orientation in which an electrical connection is provided between the interface device and the electrical connectors of the mobile telephone (401), such that the mobile telephone (401) and the flexible foldable keyboard (101) are in electrical communication.Type: ApplicationFiled: March 11, 2003Publication date: October 27, 2005Applicant: Eleksen LimitedInventors: Christopher Chapman, David Sandbach, Stuart Walkington, Timothy Fitzgerald

Publication number: 20050110773Abstract: An apparatus is disclosed for supplying input signals to a computer. A sensor having the form of a sphere has a touch sensitive surface for generating position data for touch events. The sensor includes orientation sensors that determine rotation with respect to the earth's magnetic and gravitational fields. Orientation data may be combined with position data to interpret the orientation of touch events on the surface with respect to the computer's display. Cursor movement or text may be generated from touch events. Preferably the sphere has a roughened surface that generates sound when touched. Position data is generated by processing signals from microphones under the sphere's surface.Type: ApplicationFiled: December 22, 2004Publication date: May 26, 2005Inventors: Christopher Chapman, David Sandbach
