  • Patent number: 9310940
    Abstract: Various embodiments of a capacitive touchscreen or touch panel having dual finger or hand navigation and fingerprint reading capabilities. In one embodiment, fingerprints are read and processed by the same capacitive touchscreen controller that reads and processes capacitively-sensed finger or hand touches made across the touchscreen or touch panel. A small portion of the capacitive touchscreen or touch panel is dedicated to reading an authorized user's fingerprints, while a larger or main portion of the capacitive touchscreen or touch panel is dedicated to sensing a user's finger or hand navigation across the touchscreen or touch panel.

  • Patent number: 8706542
    Abstract: A method of allocating a location-related order to one of a number of mobile agents, such as taxicabs, delivery or repair vehicles. The method involves the following steps: a) holding current order details which identify at least the location and time at which each agent is expected to become free to fulfill new orders; b) keeping a listing of locations, where each location in the listing is prioritised for an agent according to the availability of the agent to reach that location after the agent becomes free; c) receiving a new order and recording the location and time at which this order is to be fulfilled; d) deciding, based on the prioritised listing of locations, which agent(s) are most suitable to take the new order; and e) allocating the new order to the identified agent(s).

  • Patent number: 8358282
    Abstract: A device for detecting the presence of an object is provided. The device includes a light source, a current controller coupled to the light source, a sensor and a pattern detection engine. The current controller sets to provide the light source with a drive current having a pattern. The sensor is operable to receive light, notably light reflected from an object at the detection area and subsequently generates a signal in response to the light received. The pattern detection engine receives the signal from the sensor and subsequently reports the presence of the object upon determining the presence of the pattern in the signal. The object detection system is further configured to provide a navigation operation when an object is detected at the detection area.

  • Publication number: 20120182225
    Abstract: Various embodiments of systems, devices, components and methods of detecting the presence of at least one predetermined object held against a capacitive touchscreen by a user's finger or hand are disclosed. The predetermined object is held or placed against a touchscreen or touch panel, and sensed mutual capacitance signals are routed to a processor. The processor determines whether the sensed signals correspond to the at least one predetermined object on the basis of one or more predetermined ranges of mutual capacitances corresponding to the predetermined object, where the predetermined range of mutual capacitances does not correspond to a user's finger or hand. Other characteristics of the predetermined object may also be determined, such as the object's shape, orientation or electrical resistance.

    Abstract: An apparatus for controlling the position of a screen pointer for an electronic device having a display screen, includes a light source for illuminating an imaging surface with a plurality of light pulses, thereby generating reflected light pulses. A detection circuit is configured to sense light, distinguish between the reflected pulses and ambient light, and generate a low signal indication if the magnitude of the reflected pulses falls below a threshold value. An optical motion sensor generates digital images based on the reflected pulses. The motion sensor is configured to generate movement data based on the digital images. The movement data is indicative of relative motion between the imaging surface and the apparatus.
