摘要:
A handheld electronic device having a slidable display is provided. A display unit is slidably connected to a body unit at two (or more) sliding joints. A mechanical linkage constrains motion at all of the sliding joints to be substantially equal. In this manner, binding of the slidable display is avoided, since binding occurs as a result of unequal motion at sliding joints. In one embodiment, the linkage includes a gear-axle-gear assembly disposed in a recess in the body unit and constrained to rotate as a unit about the axis of the axle. The gears of this assembly are engaged with linear gear racks on the display unit.

摘要:
A vehicle communication system providing, in one embodiment, wirelessly transmitting and receiving messages regarding the status of parking spaces, such as empty or occupied. Only vehicles belonging to a predetermined set are able to decrypt such messages, in one embodiment. Message formats to comprise a group of parking spaces are described. An embodiment includes a communication mode specific for vehicles in a parking lot. An embodiment includes messages describing the shape and size of vehicle entering or leaving a parking space. Efficient methods of coding vehicle type are described. Methods of improving the operational efficiency of a vehicle communication system, including passive RF reflectors, audio and video messages, safety, courtesy and social messages, and compliance with vehicle restrictions are in some embodiments.
摘要:
Device, system and method, in a vehicle communication system, of generating lane maps. Embodiments use a plurality of location points to build up a lane, then record that lane in memory. Location points may be locations over which a first vehicle generating the lane map passes, or may be location points broadcast by a second vehicle to the first vehicle. Methods are described to wirelessly share lane information and lane maps between vehicles. Embodiments use a “confidence value” describing the confidence that the lane parameters are valid. Algorithms are described for creating and updating the confidence values. Methods of compressing and storing lane information and lane maps are described. Embodiments include geographic height in lane information.
摘要:
Intention data is used to determine an intent of a sender of a message, or other participant, in an electronic communication system such as an email system. For example, a message that is designated for sending can be compared to the sender's intention data and if a discrepancy or deficiency is detected between the sender's determined intent and the actual message then an action is taken such as providing an alert to the sender or to another person, process or device; requiring an action by the sender such as confirming the message, making an edit, checking information, etc.
摘要:
Device, system and method, in a vehicle communication system, of providing guidance, route and safety information to a driver. Embodiments use the observation and storage of signal light timing information to make recommendations. Embodiments include computation of future times of signal light changes. Embodiments use information relating to the number of vehicles, location of vehicles, and speed of vehicles in a plurality of lanes approaching a signal to recommend lane changes to a driver. Embodiments include receiving timing information wirelessly about signal timing. Embodiments include using historical information to compute a risk value for a location and then generating a recommendation to a driver responsive to that risk value. Embodiments include using speed of travel on route options to compute an expected travel time, and then generating a recommendation to a driver responsive to those computed travel times.
摘要:
Device, system and method of implementing a wireless vehicle-to-vehicle anti-collision system. Details of message formats are described, particularly efficient formats using flags and compressed data, expressing distances, both in the horizontal and vertical directions. Details of protocols are described. Details of encoding locations, headings and speed are described. In one embodiment messages are free of IP addresses and MAC addresses. Roadway elevation is included in some embodiments.

摘要:
A method of optimizing a vehicle-to-vehicle communication system is described. One embodiment uses a set of desired and defined metrics of success, combined with pre-recorded operating histories, combined with a series of simulations to optimize certain specific parameters in the vehicle-to-vehicle communication protocol.
