Abstract: A sensing decal (400) for use in the production of a sensor, includes a flexible release layer (401), a conductive ink layer (402) and an adhesive layer (403). The conductive ink layer is printed onto a first surface (404) of the flexible release layer and the adhesive layer is printed onto the conductive ink layer. The first surface includes a substantially non-uniform surface (405) and the conductive ink layer includes at least one patterned element (503-509) providing a predetermined set of electrical properties for formation of a sensor.

Abstract: An apparatus for sensing a physical attribute is shown, that includes a first track (511) defining a first electrode on a substrate (512), a second track (513) defining a second electrode on said substrate and an active film (514) in cooperation with a first sensor portion (516) of the first electrode and a second sensor portion (517) of the second electrode. The second electrode includes a first extended portion (517) to establish a first additional resistance not cooperating with the active film.

Abstract: A method of selecting an entity from a list of entities, includes providing a manually applied pressure to a touch-sensitive device and activating a range of entities in response to the manually applied pressure. The range of entities includes first and second lists of entities. Scrolling in a first direction enables selection of an entity from the first list of entities and scrolling in a second direction enables selection of an entity from the second list of entities.

Abstract: Pressure sensitive sensors are integrated with light emitting picture elements (111 to 120). Light-emitting picture elements (111 to 120) are arranged upon a substrate (151), such that located light-emitting picture elements are surrounded by a black matrix (122) of non-light-emitting regions. A sensor matrix of pressure sensitive sensor elements (131 to 139) is located at regions of the black matrix, such that sensor elements are aligned at positions over the black matrix and do not occlude the light-emitting picture elements.

Abstract: Directional data is derived from a manually-interactive-device 102 configured to generate positional data and intensity data. Initial positional data is generated, along with initial intensity data from an initial contact of a finger upon the manually-interactive-device. The manually-interactive-device has a definition sufficiently high to produce a plurality of data-points in response to the application of a single finger. Directional data is produced in response to a finger rolling or tilting operation 901 by generating additional intensity data in which variations occur to intensity values at the previously identified data-point positions.

Abstract: A sensor (102) for detecting input force includes a housing (103) having a cavity (201) and a contact element (105) which is enclosed in the cavity. The contact element and cavity provide a substantially flush profile along their respective surfaces (104, 106). The cavity includes a wall (301, 302, 303) having a sensing device (304) attached thereto and the contact element provides a physical contact between the contact element and the sensing device on application of a mechanical interaction to the surface of the contact element.

Abstract: The detection of multiple manual interactions upon a touch-pad is shown. Drive lines intersect a scan lines and each intersection between a drive line and a scan line includes an element of variable resistance. A scanning processor energises the drive lines and monitors the scan lines. The scanning processor is configured to identify positions of manual interaction, validate identified positions to identify potentially erroneous positions and remove positions identified as erroneous. However, removed positions are re-introduced when they are not in the vicinity of other identified positions.

Abstract: Manual selection of an entity from a list of entities displayable by scrolling is facilitated. A list (101) of selectable entities is established. A range (1002) is identified of selectable entities (E006 TO E050) within the list. A portion (1003) of the range is displayed and output signals are received in response to manually applied pressure. Scrolling is performed through the range, not directly through the list, at a rate related to the manually applied pressure. The range is reduced during the scrolling operation to remove entities that are clearly not to be selected.

Abstract: A method of manufacturing a sensing decal (400), a sensing decal and a method of providing a sensing decal to a device (702), in which the method of manufacture includes providing a flexible release layer (401) having a substantially non-uniform surface (405) and printing a conductive ink layer (402) onto the non-uniform surface. An adhesive layer (403) is printed onto the conductive ink layer to produce the sensing decal. The decal can then be applied to a surface (701) of a device and the flexible release layer is removed.

Abstract: Illumination functionality is combined with a touch-sensing functionality. A first electrical conductor and a second electrical conductor are located on a substrate. A pressure-sensitive element (113) is connected across the conductors and a light-emitting device (114) is also connected between the conductors. A control circuit alternates between energizing the pressure-sensitive element with current flowing in a first direction and driving the light-emitting device with current flowing in an opposite direction.

Abstract: A flexible sensor (201) comprises a first conductive layer (202) and a second conductive layer (203). The first conductive layer and the second conductive layer define a sensing region (205) for determining an interaction, such as a mechanical interaction. The first conductive layer comprises a first substrate (206) having a plurality of conductive rows (207) printed thereon and the second conductive layer comprises a second substrate 208 having a plurality of columns (209) printed thereon. The first conductive layer and the second conductive layer are constrained by a constraining means (505) which holds the two layers together but permits movement of the layers perpendicular to each other in the sensing region.

Abstract: A detection element (104) is energised. The detection element is substantially non-conductive without an application of pressure and becomes increasingly conductive in response to pressure application. A processor (101) is interrupted from a low-power dissipation state in response to a first detectable application of pressure by the detection-element. The processor is then configured to monitor further pressure applied to the same detection element.
