Method and apparatus for choosing a desired field of view from a wide-angle image or video

Abstract: A wide-angle camera will collect wide-angle images. A portion of the wide-angle image (desired field of view) will be selected based on accelerometer readings. More particularly, to keep the desired field of view of a camera in an appropriate position, a correction is made to the tilt and roll of the desired field of view by using motion sensors to determine the horizon based on measuring the direction of gravity. A correction is also made to the yaw of the desired field of view using motion sensors to determine a forward facing position when the user is in motion. Because the desired field of view is corrected for variations resulting from user activity, any image collected from the camera is more likely to be pointed at a desired position.

Interference-robust coded-modulation scheme for optical communications and method for modulating illumination for optical communications

Abstract: An interference-robust coded-modulation scheme for optical communications and a method for modulating illumination for optical communications include optical signal transmitters connected to signal multipliers. The signal to be transmitted is multiplied by a pseudo-random noise code and transmitted within the transmitter emissions. A receiver converts the received modulated light and correlates the received signal. An estimate of the signal to be transmitted is made by multiplying the received signal by the noise code and correlating such multiplication over the length of the code. A threshold switch outputs the correlation result to a bit estimator approximately when a deterministic peak of the output signal exceeds a threshold.

A method and apparatus for determining the location of a unit using neighbor lists

Abstract: A method and location determination module is provided for determining a location of one of a plurality of units (16A, 16B, 16C, 12, 14) using neighbor lists (212). Each unit is communicatively coupled to at least some of the other plurality of units (16A, 16B, 16C, 12, 14), where at least some of the plurality of units (16A, 16B, 16C, 12, 14) are reference units, whose locations are known. The units communicate with other (16A, 16B, 16C, 12, 14) nearby units within communication range, to establish neighbor lists (212). A unit to be located then identifies an aggregate value corresponding to the number of occurrences of the reference units in the neighbor list (212) of the unit to be located and the neighbor lists (212) of each of a group of associated units. The location of the unit to be located is then determined, based upon the known locations of the reference units and the number of identified occurrences of the reference units in the corresponding neighbor lists (212).

User interface for a vehicle installed communication device

Abstract: A radio communication device (100) for use in a public safety vehicle is provided with a user interface that combines tactile landmarks in the form of global tactile landmarks and local tactile landmarks along with affordances to orient a user's hand and fingers in conjunction with a sequential task flow interface) for mission critical tasks. Communication device (100) comprises a housing (102) having mission critical controls (116) comprising a pursuit dial (122) mounted on a circular platform (206) with siren controls (124) and light controls (126) grouped on either side of the platform. The mission critical controls (116) are laid out in a manner that provides a sequential user flow across escalating urgency. Ridges (208, 210), chamfered edges (402, 404) and edge reliefs (502) provide further affordances so that a user can intuitively position hand and fingers to locate various controls without having to visually focus on the communication device, thus allowing the user to focus on the current mission.

Method and apparatus for bridging calls between two disparate push-to-talk systems

Abstract: A PTT bridging gateway between a first PTT system and a second disparate PTT system: receives an invitation to a first client to join a first group call for a first group comprising multiple member clients on the first PTT system, wherein the first client is one of the member clients of the first group; determines that the first client is mapped to a second group comprising multiple member clients on the second PTT system; and initiates a second group call to the multiple member clients on the second PTT system.
