摘要： A blind spot warning method is disclosed for a tow vehicle. The method includes determining whether a trailer is connected to the tow vehicle. Based on the determination whether the trailer is connected to the tow vehicle, the determines whether a blind spot zone corresponds to the tow vehicle or to the tow vehicle and the trailer. At least one instruction is sent to a user interface of the tow vehicle for displaying an image for viewing by a driver of the tow vehicle. The displayed image indicates the determination whether the blind spot zone corresponds to the tow vehicle or to the tow vehicle and the trailer, and indicates a presence or absence of at least one other vehicle disposed in the blind spot zone.

摘要： In one embodiment, a ladar system includes a laser transmitter with at least one semiconductor laser having a pulsed laser light output. A laser drive circuit is connected to said at least one semiconductor laser and adapted to electrically drive said at least one semiconductor laser in a predetermined sequence. A laser beam steering mechanism is adapted to scan the pulsed laser light output sequentially through the field of view. A two-dimensional array of light sensitive detectors receive reflected light and an integrated circuit calculates a direct time of flight distance measurement.

摘要： A system for landing or docking a mobile platform is enabled by a flash LADAR sensor having an adaptive controller with Automatic Gain Control (AGC). Range gating in the LADAR sensor penetrates through diffuse reflectors. The LADAR sensor adapted for landing/approach comprises a system controller, pulsed laser transmitter, transmit optics, receive optics, a focal plane array of detectors, a readout integrated circuit, camera support electronics and image processor, an image analysis and bias calculation processor, and a detector array bias control circuit. The system is capable of developing a complete 3-D scene from a single point of view.

摘要： A vehicle and ladar sensor assembly system is proposed which makes use of forward mounted long range ladar sensors and short range ladar sensors mounted in auxiliary lamps to identify obstacles and to identify potential collisions with the vehicle. A low cost assembly is developed which can be easily mounted within a body panel cutout of a vehicle, and which connects to the vehicle electrical and computer systems through the vehicle wiring harness. The vehicle has a digital processor which interprets 3D data received from the ladar sensor assembly, and which is in control of the vehicle subsystems for steering, braking, acceleration, and suspension. The digital processor onboard the vehicle makes use of the 3D data and the vehicle control subsystems to avoid collisions and steer a best path.

摘要： A method for avoiding a vehicle undercarriage collision includes identifying an object within a field of view of a vehicle with at least one sensor. a size of the object is determined by comparing the size of the object to a predetermined height of the undercarriage of the vehicle. An indication is provided if the object will collide with an undercarriage of the vehicle

摘要： A dual mode ladar system includes a laser transmitter having a wavelength of operation and a modulator connected thereto to impose a modulation thereon. The modulator is configured to impose amplitude modulation and/or frequency modulation. Diffusing optics illuminate a field of view and an array of light sensitive detectors each produce an electrical response signal from a reflected portion of the laser light output.

摘要： A collision mitigation system makes use of ladar sensors to identify obstacles and to predict unavoidable collisions therewith, and a duplex radio link in communication with secondary vehicles, and a number of external airbags deployable under the control of an airbag control unit, to reduce the forces of impact on the host vehicle, secondary vehicles, and bipeds and quadrupeds wandering into the roadway. A suspension modification system makes use of ladar sensors to identify road hazards, and make adaptations to a number of active suspension components, each with the ability to absorb shock, elevate or lower the vehicle, and adjust the spring rate of the individual wheel suspensions.

摘要： A lightweight, inexpensive LADAR sensor incorporating 3-D focal plane arrays is adapted specifically for modular manufacture and rapid field configurability and provisioning. The sensor generates, at high speed, 3-D image maps and object data at short to medium ranges. The techniques and structures described may be used to extend the range of long range systems as well, though the focus is on compact, short to medium range ladar sensors suitable for use in multi-sensor television production systems and 3-D graphics capture and moviemaking. 3-D focal plane arrays are used in a variety of physical configurations to provide useful new capabilities.

摘要： A vehicular collision avoidance system comprising a system controller, pulsed laser transmitter, a number of independent ladar sensor units, a cabling infrastructure, internal memory, a scene processor, and a data communications port is presented herein. The described invention is capable of developing a 3-D scene, and object data for targets within the scene, from multiple ladar sensor units coupled to centralized LADAR-based Collision Avoidance System (CAS). Key LADAR elements are embedded within standard headlamp and taillight assemblies. Articulating LADAR sensors cover terrain coming into view around a curve, at the crest of a hill, or at the bottom of a dip. A central laser transmitter may be split into multiple optical outputs and guided through fibers to illuminate portions of the 360° field of view surrounding the vehicle. These fibers may also serve as amplifiers to increase the optical intensity provided by a single master laser.
