Abstract: A portable GPS/radio unit (10) communicates over a wireless radio network (12) with at least one other such unit. The unit (10) may transmit radio signals over the network (12) indicative of the unit's location. The unit (10) includes a single, push-to-talk button (38) that may be pressed to both transmit a voice communication and to initiate transmission of location data. The unit (10) also includes a “polling” function that requests location data from other units, an auxiliary coding system that codes or encrypts all transmitted data, and an emergency message feature that facilities the transmission and receipt of emergency messages.

Abstract: Natural-phenomenological information is personalized to the unique requirements of a subscriber and distributed to the subscriber. Natural-phenomenological data is gathered from a variety of sources, such as current ground observations, forecast conditions, satellite images, and radar data. Personal preferences of the subscribers are also gathered and stored, such as activities of the subscriber, geographic locations of the activities, sensitivities of the subscriber to natural-phenomenological conditions, calendar information of the subscriber, and modes of delivery. The personal preferences of the subscriber are used as a filter to identify the natural-phenomenological data that is particularly useful to the subscriber, and the resulting information is delivered to the subscriber. The subscriber identifies the destination device that the information is delivered to. The invention is extensible to support new sources of natural-phenomenological information and new output devices.

Abstract: A spatial data search method, system and apparatus for identifying particular data of significance around a reference vector through the spatial data. The method involves determining a reference vector within a spatial region for which spatial data exists, loading a portion of the spatial data including the data around the reference vector into a memory buffer, and searching the spatial data in a prioritized order. The method, system and apparatus have particular utility in searching geographic data for a terrain awareness and warning system (“TAWS”) and display in an aircraft. Embodiments of the present invention provide advantages over existing sequential and radial search methods, significantly reducing the processing and calculations required and providing faster alerts to pilots.

Abstract: A system and method for filtering various targets (such as ground vehicles, stationary objects, and aircraft) from display on a display screen within the cockpit of an “Own Ship” aircraft. The system and method withhold from display any non-exempt targets that have an altitude that is either: (1) greater than an upper-threshold altitude; or (2) less than a lower-threshold altitude. The upper-threshold altitude and the lower-threshold altitude may be set to user-specified, customized values as desired to accommodate current flying conditions. In addition, the system and method may also be configured to operate in a plurality of operating modes, each of which features a different upper threshold altitude/lower threshold altitude combination. The system and method are preferably configured to reset certain threshold altitudes to pre-defined default altitudes in response to the aircraft landing.

Abstract: A friction mount apparatus for supporting an electronic device (10) on a surface (14). The apparatus (10) includes a body (16), anchors (18,20,22), and a receiving member (24). Body (16) includes a recessed surface (30) on the bottom thereof into which a foam layer (36) is secured, wherein the foam layer (36) contacts a mounting surface (14) and resists moving relative to the surface (14). The anchors (18,20,22) are connected to the body (16) via flexible necks (38,40,42) and have bottom surfaces formed of soft material and weighted cores to press the bottom surfaces against the mounting surface to resist movement relative to the mounting surface (14) and thus further stabilize the apparatus (10). The receiving member (24) is secured to a top surface of the body (16) and is adapted to releasably retain an electronic device (12).

Abstract: A navigation device is provided that includes a GPS input that receives GPS information from a GPS satellite. The system also includes a non-GPS input that receives real-time content from a non-GPS source. The real-time content includes updates to travel conditions. The system also includes a navigation module that analyzes the updates from the non-GPS source in conjunction with the GPS information form the GPS satellite.
