Abstract: A device and method of keeping litter in an animal cage away from equipment in an animal cage. Embodiments comprise two or more walls to define three zones in an animal cage: an equipment zone, a channel zone, and an outsize zone. The channel zone connects the outside zone with the equipment zone. Baffles in the channel zone permit access by animals but block some fraction of litter from passing from the outsize zone into the equipment zone. Embodiments include a weighing scale in the equipment zone. Embodiments include shapes that constrain devices or equipment to predetermined locations within a cage. Embodiments include methods of use and use in a vivarium.

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: 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 system, method and transponder for use in V2V communication, safety and anti-collision systems uses 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 is responsive to demand and range. Methods of obtaining the as-used values include using equations and ranges. Embodiments include a hybrid protocol using both TDMA and CSMA. The invention is free of both central authority and road-side equipment (RSU).

Abstract: A vehicle-to-vehicle (V2V) communication transponder for use in V2V communication, safety and anti-collision systems incorporating a location point store and a lane records store, wherein the lane records are constructed by the transponder from the point in the location point store, location points are received from other moving transponders, and lane records are shared between transponder response to a request. Separate source counts are kept for internally generated and shared lane records. Methods of sharing are described. Lane types are also derived from the location point store and other vehicle behavior. No central authority, road-side equipment, (RSU), or pre-determined lane maps are required. Embodiments include a hybrid protocol using both TDMA and CSMA. Some embodiments are free of MAC and IP addresses. Embodiments include equipped vehicles and V2V system using the transponder.

Abstract: A computer has a display, keyboard and two main component parts. The components each have an L-shape and are linked together to enable sliding movement in substantially one plane in a first direction. The linkage also enables movement orthogonally with respect to the first direction in another plane, such that the components transition from a closed position of the computer in which the components interfit together to form a first right rectangular prism and in which the display is exposed, to an open position having a second right rectangular prism shape in which the keyboard is exposed adjacent to and in the same plane as the display.

Abstract: In one embodiment, a video signal is displayed on a display screen in two or more resolutions. The video signal may be of a first resolution and the display screen may be set to a second resolution. In one embodiment, the video signal resolution is of a size that is greater than the size of the display screen resolution. The method includes displaying a first portion of the video signal in a first resolution in a first region of the display. A second portion of the video signal is then displayed in a second resolution in a second region of the display. The second resolution is a resolution that displays at least a portion of the video signal that would be off screen if the video signal is displayed in the first resolution. Accordingly, more of the signal can be displayed on the screen.
