Abstract:
A method of creating a chording keyboard mapping table is described. An exercise is created that is performed by users of a keyboard for which a mapping table is desired. The psychomotor performance of the users' transitions between chords is recorded—as distinct from performance relating to chords. A first trial keyboard mapping table (from chords to symbols) is created, and the effectiveness of that table is measured by applying it to a text corpus and measuring the total psychomotor cost to enter that corpus with that table. The table is then permuted, and the cost recomputed. Trial tables are repeatedly permuted, with one or more preferred tables being used as the basis for the next iteration of permutations. This continues until a terminating event, such as minimal improvement, is reached. Variations as embodiments are described. Software to implement the method is claimed.
Abstract:
An electronic interval timer in a regular dodecahedron case is described. The timer is set by orienting the timer so that the face with the time desired is uppermost. The timer is free of buttons, switches, and electronic displays. It is sealed for ruggedness and water-resistance, and free of a battery door. Detection of motion, taps, and orientation is via an accelerometer and a processor; it is free of mechanical motion and orientation switches. The timer indicates start and end of set time intervals with speech announcements or tones. Two time intervals may run concurrently by orienting the timer to a second time. The timer may be programmed via an orientation sequence. Taps may be used to request a time remaining announcement or to set volume. Functions include a stopwatch. Shells have seam lines on polyhedral edges and pin-and-socket connections for strength. A molded air-gap provides for pressure equalization while maintaining water resistance.
Abstract:
A vehicle-to-vehicle (V2V) communication system, method and transponder for use in V2V communication, safety and anti-collision systems is described, using a continual, iterative consensus algorithm involving a consensus subset of vehicles within a communication range. The consensus set of vehicles participating in the consensus algorithm may not be the same. The algorithm comprises determining a parameter value used by the vehicles in the consensus set, then averaging, with modifications and rate of change limitations, the values from the consensus set for next use by each transponder. Parameters include two axis of location, elevation, transmit power and time base. Transmit power may be response to demand and range. Methods of obtaining the as-used values are described, as are equations and ranges. Embodiments include a hybrid protocol using both TDMA and CSMA. No central authority or road-side equipment (RSU) is required.
Abstract:
A method of connecting a user device anonymously to a remote operator, via an intermediate anonymizing server is described. In this way, a remote operator may control the device, without the remote operator knowing the identity of the owner or of user of the device. A remote operator might provide medical support or entertainment. The user of the device is provided with a connection key, which is then further given by the user to a desired remote operator. Both the user and the remote operator provide the anonymizing server with the connection key. The anonymizing server opens a chat room uniquely associated with the connection key. Electronic connectivity is provided by forwarding messages between the user device and the remote operator through the chat room. No other access to the chat room is permitted. The anonymizing server does not store the connection key. No user application is required.
Abstract:
Devices, a set of devices, and methods are described to create coordinated, or synchronized, displays of colors by worn fashion accessories, such as necklaces, earrings, shoes, belts, and the like. A master device is defined that sends broadcast, wireless commands to slave devices, which respond with colors and timing in a synchronized way, typically to enhance the experiences of the wearers. Synchronization may include simultaneous lighting, sequential lighting, the same color or coordinated colors. A group ID in messages is defined so that a first set of fashion accessories on a first group of wearers may be controlled by one master, while a nearby second set of fashion accessories worn by a second set of wearers controlled by a second master do not conflict. Operation, including changes from a standby state to an operational state is automatic, using, for example motion detection.

Abstract:
A vehicle-to-vehicle (V2V) communication transponder for use in V2V communication, safety and anti-collision systems using only a vehicle location for vehicle ID is described. Message embodiments are free of pre-assigned permanent vehicle identification. A hybrid TMDA and CSMA protocol is used. Vehicle position is broadcast as an offset in distance units from a pre-defined geographical grid in degree units. A transponder may proxy for non-equipped vehicle. A proxy handoff and message coding for a proxy message are described. Embodiments are free of MAC and IP addresses. No central authority or road-side equipment (RSU) is required. Embodiments include equipped vehicles and V2V system using the transponder. Embodiments include equipped vehicles and V2V system using the transponder.
Abstract:
A vehicle-to-vehicle (V2V) communication transponder for use in V2V communication, safety and anti-collision systems using a hybrid protocol combining time-division multiplexed access (TDMA), with collision sense multiple access (CSMA) protocol. The TDMA frame is broken into regions, a priority and emergency TDMA region, and a non-priority CSMA region. The sizes of the TDMA regions change dynamically based on demand, with the CSMA region using the remaining time slots. Transponders self-select time slots; selected slots are held until a new time slot selection criteria; all transponders participate in notifying a transponder of a time slot message collision. An inter-transmission guard time may be dynamic based on range. Embodiments are free of MAC and IP addresses. No central authority or road-side equipment (RSU) is required. Embodiments include equipped vehicles and V2V system using the transponder.
Abstract:
An electronic interval timer in a dodecahedron case is described. The timer is set by turning uppermost one of 11 faces; and reset by turning uppermost the 12th face. In one embodiment, the timer is free of buttons, knobs, springs, time displays, electronic visual indicators and openings in the case. Time interval completion is announced via audible tones or speech. An aggregate time interval may be set equal to the sum of legends on more than one face. The timer detects carrying such that a running time interval is not modified. The timer may be programmed via a sequence of uppermost sides. Modes may be selected via shaking or tapping. Time remaining may be announced, an interval cleared, or an interval restarted responsive to detected motion. Other polyhedral shapes may be used. Claims include a method of setting a time interval; and specific ordering of face legends.

Embodiments include the use of IEEE 802.11 wireless protocol, the use of a standard track-mount power supply; the use of a two-axis tilt and pan mechanical mount; hardware to permit horizon correction; modifications to a camera enclosure to support an antenna inside the enclosure and access to camera controls; use of multiple antennas; use of a cover plate at the front of the enclosure; use of visible light or infrared light LEDs on the cover plate; configuration to use dual-circuit tracks; use of separate circuits in the track to power the visible light and infrared light LEDs separately. A method of manufacturing the fixture is described.
