Abstract: A terrain awareness system (TAS) provides LOOK-AHEAD/LOOK-DOWN as well as LOOK-UP terrain advisory and warning indications to the pilot of an aircraft of a hazardous flight condition. The TAS includes an airport data base as well as a terrain data base that is structured to provide various resolutions depending on the topography of the particular geographic area of interest. Navigational data from a satellite-based navigational system, such as a global positioning system (GPS), is used to provide a LOOK-AHEAD/LOOK-DOWN and LOOK-UP terrain advisory and terrain warning indications based upon the current position and projected flight path of the aircraft. Since the terrain advisory and the warning signals are a function of the flight path of the aircraft, nuisance warnings are minimized.

Abstract: A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump through a manifold which sequentially connects each cell independently to the pump. The manifold controls the flow of fluid in the air cell distribution system by means of a system of valves and senses the pressure in each cell by means of a transducer. A microcomputer is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves, a pressure signal from the transducer can be generated for each cell. The pressure signals are received by the microcomputer and are correlated with the predetermined comfort data to generate a control signal which activates the pump. In this manner each of the cells can be individually inflated or deflated to the desired pressure level.

Abstract: Methods for GPS-assisted determination of location coordinates of a mobile user or selected position on or adjacent to the Earth's surface with improved accuracy. Elevation readings from an altimeter or barometer are integrated with readings of the GPS-determined elevation coordinate for that location, using Kalman filter techniques, minimum least square techniques, or comparison of certain statistically defined parameters associated with the altimeter and GPS variables, such as the standard deviation of the expected errors in these variables. The resulting elevation coordinate may be a statistical blend or filtered blend of the altimeter value and a GPS-determined value for the elevation coordinate; or this resulting elevation coordinate can be chosen to be one or the other of these values, based upon comparison of time varying statistical parameters corresponding to the altimeter and the GPS.

Abstract: A remote computer I/O apparatus comprising of a set of position tracked wireless user manipulated bodies and a host adapter station. Input is derived from the real-time position tracking telemetry received from each user manipulated body over a wireless transmitter housed in each body. Location determination is performed on a relative clustering basis using photonic light pulses, on a relative absolute special positioning basis using ultrasonic triangulation between bodies, or on a relative absolute spatial positioning basis between each body and the host adapter. For output each body may store or receive video and audio generated respectively by the controlled computer or by an sound generating device such as a soundcard running on the same. Stored feedback is emitted from each body upon receipt of playback signals transmitted to any selected bodies causing them to display stored video on a local body display or to emit stored audio segments out a local body speaker.

Abstract: The invention is directed to a system for determining the changes in gear ratio for an automatic transmission of a vehicle. Such an automatic transmission can be a fully automatic shifting step transmission or a known continuously variable transmission or an automated manual shift transmission. For determining the changes in gear ratio, a detection device for detecting the vehicle road speed and a determination device for determining the gear ratio changes of the automatic transmission are provided at least in dependence upon a first adaptation quantity. The essence of the invention is that the first adaptation quantity is determined from a time-dependent trace of the road speed of the vehicle. With the system, information is provided as to whether the vehicle is, at a particular point in time, in city traffic (low vehicle speed), on a country road (average vehicle speed) or on an expressway (high vehicle speed). This data is obtained in a simple manner via an evaluation of the trace of the road speed.

Abstract: A CPU 30 first receives data of accelerations Gx and Gy applied respectively along a longitudinal axis and a lateral axis of a vehicle (S20). The CPU 30 then calculates an arithmetic value fx from the acceleration Gx in the longitudinal direction according to specified arithmetic operations, and calculates an arithmetic value fy from the acceleration Gy in the lateral direction according to specified arithmetic operations (S22). The CPU 30 subsequently projects vectors based on the arithmetic values fx and fy in a preset direction a to yield projective components of the vectors, and determines a sum fa of the projective components (S24). The CPU 30 compares the projective component fa with a threshold value fth(a) previously set for the direction a, and determines whether or not the projective component fa is greater than the threshold value fth(a) (S26).

Abstract: A vehicular constant-speed running system converges a vehicle speed control of a vehicle quickly to a target vehicle speed when the vehicle is set in a cruise control mode. The vehicular constant-speed running system includes a constant-speed running section for controlling a throttle opening independently of an accelerator opening to maintain a vehicle at a target vehicle speed. It also includes an initial opening setting section which, at the time of transfer by the constant-speed running section, sets the throttle opening before the transfer to an initial value at the time of the transfer if the throttle opening is in a region which is preset based on either the vehicle speed at the time of the transfer or a parameter correlated with the vehicle speed. If the throttle opening is not in this region, the initial opening setting section sets the same throttle opening to the upper limit and/or the lower limit of that region.

Abstract: A system for tracking an object (for example tracking an automobile as it moves over streets) using an electronic map and a GPS receiver. The GPS receiver accepts data from a number of satellites and determines a GPS derived position and velocity. Based on the previous position of the object, the GPS derived position, the velocity, the DOP and the continuity of satellites for which data is received, the system determines whether the GPS data is reliable. If the GPS data is reliable, the previous position of the object is updated to the GPS derived position. The updated position is then matched to a map of roads.
