A method for remote object sensing on-board a vehicle includes employing compressive sensing to analyze a waveform originating from an on-vehicle low-resolution radar imaging system and reflected from a remote object. The compressive sensing includes generating a matrix including a temporal projection, a Fourier transform, and an integral term configured to analyze the reflected waveform. Leading and trailing edges of the remote object are identified by employing a norm minimization procedure to reconstruct a range profile based upon the reflected waveform analyzed by the compressive sensing.

A linear motion device includes a rod extending along a longitudinal axis, and a plurality of actuator units. Each of the plurality of actuator units includes at least one Shape Memory Alloy (SMA) element that is attached to a coupling mechanism. The at least one SMA element of each if the plurality of actuator units moves the coupling mechanism along the longitudinal axis, and into grasping engagement with the rod. Each actuator unit moves the rod a unit movement distance along the longitudinal axis in response to a control signal. The plurality of actuator units are actuated repeatedly in a cyclic order to move the rod in a continuous linear motion a distance greater than the unit movement distance of each of the plurality of actuator units.

An augmented reality system includes a vision output device for displaying virtual images. A sensing device captures an image within a reference frame. The vision output device is captured within the image. A processing unit identifies the vision output device within the reference frame of the captured image and localizes the vision output device within the reference frame of the captured image for identifying an absolute position and orientation of the vision output device within the reference frame of the captured image. The vision output device generates virtual displays to a user at respective locations based on the absolute position and orientation of the vision output device within reference frame of the captured image. The sensing device captures a user's selection of a virtual control. The processing unit identifies the selection of the virtual control within the captured image and enables a control action of a controllable device.

A system includes a radar antenna and a radar controller. The radar controller generates two narrowband radar signals, each narrowband radar signal having substantially constant frequency, the frequencies of the two narrowband radar signals differing from one another. The controller operates the radar antenna to transmit each of the generated narrowband radar signals as a transmitted signal, each transmitted signal being characterized by a transmitted power. The controller also measures a received power of received signals that are received by the radar antenna, each received signal including a portion of a corresponding one of the transmitted signals that was returned from an object or from a calibration surface at a known calibration range. A processor operating in accordance with programmed instructions calculates a range to the object on the basis of the transmitted and received powers.

A directional horn may include at least one group of a plurality of speakers or audio emitters. The audio emitters may each emit and audio signal at a same frequency. A processor may control a relative phase difference and relative gain difference between each audio signal, based on a determined direction. The directional horn may be positioned on a vehicle. The determined direction may be based on a direction indicated by a driver controlling the vehicle, external environmental factors, vehicle dynamics, or other factors.

An automatically adjusting mirror system including a mirror assembly, a head position sensor configured and arranged to detect a pose of a head of a driver of a vehicle, and a master controller in communication with the mirror assembly and head position sensor. The master controller is configured to receive input from the mirror assembly and head position sensor, and adjust the mirror assembly based on the input from the mirror assembly and the input from the head position sensor to maintain a line of sight for the driver.
