摘要： A programmable input/output device for use with a programmable logic device (PLD) is presented comprising an input buffer, an output buffer and programmable elements. The programmable elements may be programmed to select a logic standard for the input/output device to operate at. For instance, a given set of Select Bits applied to the programmable elements may select TTL logic, in which case the input and output buffers would operate according to the voltage levels appropriate for TTL logic (e.g., 0.4 volts to 2.4 volts). For a different set of Select Bits, the GTL logic standard would be applied (e.g., 0.8 volts to 1.2 volts). The invention enables a single PLD to be used in conjunction with various types of external circuitry.

摘要： In one preferred embodiment, an aircraft marshaling wand controller displays aircraft marshaling instructions to a pilot on a video display monitor on-board an aircraft, such as an aircraft on an aircraft carrier. When an aircraft marshal uses arm motion gestures to form aircraft marshaling instructions for the pilot on the aircraft, the wand controller of the present invention senses or detects those gesture motions, and generates digitized command signals representative of those gesture motions made by the aircraft marshal. A wireless transceiver then transmits those digitized command signals to the aircraft for display on the video monitor for viewing by the pilot.

摘要： A Hall-effect system for providing inputs into a processor includes at least one magnet for establishing a magnetic field, a remote sensor unit and a receive station. The magnet is sized and adapted to be worn on a user's finger, while the remote sensor unit is adapted to be worn on a user's thumb. The remote sensor unit includes a Hall-effect sensor that senses changes in the magnetic field due to the motion of the magnet relative to the Hall-effect sensor. The Hall-effect sensor detects the magnetic field changes, and the remote sensor unit generates a sensor output corresponding to the magnetic field changes. The receive station is connected to the processor. The receive station receives the output from the remote sensor unit and converts the sensor output into an input for the processor.

摘要： A method involves transmitting a first signal to a device, the first signal comprising vehicle identification data and vehicle operational data, receiving a second signal from the device, the second signal comprising road and lane information and vehicle information vectors of other vehicles transiting the road in range of the device, and determining a collision risk based upon the received second signal. The method involves the range-limited communication of vehicle information vectors among a network of devices. The method may include transmitting an operational signal to a vehicle controller, wherein the operation of a vehicle, such as speed, braking, and steering, is altered by the vehicle controller based upon the received operational signal. The method may involve, if the determined collision risk exceeds a predetermined threshold, the transmission of a warning signal by a vehicle computer to a vehicle operator via a warning device controlled by a vehicle controller.

摘要： Disclosed is a floating sensor system having a casing that encloses a microcontroller. The microcontroller includes a digital processor and a non-volatile memory. The casing also encloses a data bus that connects the microcontroller to an external environment sensor, an RF transceiver, and a battery. The non-volatile memory includes a history file that maintains a record of events sensed by the external environment sensors. The digital processor is configured to establish a pattern of expected external environmental behavior based on the record of events. The digital processor is also configured to emit a signal through the RF transceiver from the system when an unexpected event occurs.

摘要： An object localization and tracking system includes a plurality of tags that are placed on respective objects. Each tag includes a transceiver and at least three orthogonal antennas to receive RF energy in a three dimensions. The tag transceiver and antennas cooperate with other tag antennas and transceivers to establish a tag (object) RF network. Each tag further includes a microprocessor, and sensors that determine tag position and relative position of other tags in the tag RF network. A user interface is connected to one of the tag microprocessors. A predetermined algorithm, which describes desired positional information for each tag in the RF network (and its corresponding object), is input into one of the microprocessors through the user interface. A tag audible or visual alert activates when the actual positional information of the tag (and the attached object) do not correspond to the desired positional information.
