    摘要： A transfer function is provided for use with computer pointing devices such as trackpads. The transfer function includes a first component having characteristics of a positional transfer function and a second component having characteristics of a velocity-based transfer function. The first (positional) component and the second (velocity-based) component of the transfer function are blended so that the transfer function exhibits purely positional behavior in response to a first range of inputs and exhibits combined positional and velocity-based behavior in response to a second range of inputs. The first range of inputs may, for example, correspond to a region in the input coordinate space that is bounded by a circle having a predetermined threshold radius.

    摘要： Objects and their placement within a particular scene may be characterized using structured light with no or minimal manual intervention or calibration to the scene. The structured light pattern may be rendered with visible light, yet imperceptible to users, by generating a set of opposing excursions in one or more image properties for durations which are shorter than the integration time of the human eye. A set of assumptions and ongoing testing of those assumptions against physical objects identified within the environment allows characterization of the scene and the objects therein.

    摘要： Multiple disparate wireless units sharing of antennas are described herein. In one embodiment, an apparatus includes, but is not limited to, a first wireless communication unit of a first wireless communication standard, where the first standard includes selecting one of two antennas provided. The apparatus further includes a second wireless communication unit of a second wireless communication standard, where a first antenna and a second antenna are shared by the first and second communication units. Other methods and apparatuses are also described.

    摘要： A device for use in, and system for, a vehicle-to-vehicle (V2V) communication and safety system that uses a hybrid combination of TDMA and CSMA protocols. The synchronized TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. The TDMA portions of a repeating time interval uses self-assigned dense time slots for high-priority safety messages, with one portion for emergency vehicles and road-side units. The CSMA protocol uses remaining available time for lower-priority and overflow messages. The higher-priority time interval classes change size dynamically based on the number of current transmissions. Modulation schemes, but not data link formats, use existing Standards. Embodiments include optimized traffic flow and signal timing.

    摘要： A transceiver in a vehicle-to-vehicle (V2V) communication and safety system that regularly broadcasts safety messages, comprising location, heading and speed, of a subject vehicle, that are free of MAC and IP addresses. The V2V system uses the location of the subject vehicle for vehicle identification, in place of a pre-assigned vehicle ID. Some embodiments broadcast safety message in self-assigned time slots in a synchronized TDMA broadcast architecture, with unusually short inter-message gaps and unusually short messages. The TDMA frame is partitioned into three prioritized time interval classes with differing priorities and dynamically changing sizes based on demand of higher-priority messages. Time slot selection uses weighted algorithms. Selected time slots are held until either a message collision or a timeout occurs. A transceiver equipped vehicle may proxy a different subject vehicle. Embodiments include optimized traffic flow and signal timing.
