摘要:
Augmented reality environments allow users in their physical environment to interact with virtual objects and information. Augmented reality applications are developed and configured to utilize local as well as cloud resources. Application management allows control over distribution of applications to select groups or all users. An application programming interface allows simplified control and distribution of tasks between local and cloud resources during development and post-development operation. This integration between local and cloud resources along with the control afforded by application management allows rapid development, testing, deployment, and updating of augmented reality applications.

The present invention features a personal computing device that may be powered by a single battery having a single lithium-ion cell or by a plurality of lithium-ion cells connected in parallel. The personal computing device may provide computing power comparable to that of conventional laptop computers and execute an operating system and application software comparable to that executed by conventional laptop computers. Furthermore, the battery's time between charging, when used to power the personal computing device, may be similar to the time between charging of a multi-cell battery when used to power a conventional laptop computer.

Device, system and method, in a vehicle communication system, of transmitting a risk value in a message, wherein the risk value identifies quantitatively a risk of vehicle collision. Embodiments determine risk value by combining sub-risk values wherein sub-risks comprise: (i) vehicle behavior; (ii) weather and road conditions; (iii) current traffic; and (iv) location history. Embodiments include driver warnings responsive to the risk value in a received message. Embodiments include a collision type in a message. Embodiments include unique features of: risk is applicable to receiving vehicles; risk is applicable to a geographical region; computation and storage of location histories; messages free of IP and MAC addresses; haptic devices used for driver warning.
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.

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.
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:
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.

A method enables power savings in an OLED display by reducing the size of the screen in an OLED display when the screen is not in use. For example, if the OLED display receives no input from the user for a predefined time period, the size of the screen is reduced in order to decrease the power consumption of the OLED display.
