Abstract: A Lidar system, photonic chip and method of detecting an object. The photonic chip includes a laser and one or more photodetectors. The laser generates a transmitted light beam. The one or more photodetectors are receptive to a reflected light beam that is a reflection of the transmitted light beam from an object and generate an electrical signal as output in response to the reflected light beam signal. An amplifier is configured to amplify a signal related to the reflected light beam to amplify the output signal of the one or more photodetectors. A processor determines a parameter of the object from the amplified output signal.

Abstract: A vehicle, Lidar system and method of detecting an object is disclosed. The Lidar system includes a photonic chip having a laser, an on-chip frequency shifter, a combiner and a first set of photodetectors. The laser generates a transmitted light beam and an associated local oscillator beam within the photonic chip. The on-chip frequency shifter shifts a frequency of the local oscillator beam. The combiner combines a reflected light beam with the frequency-shifted local oscillator beam, wherein the reflected light beam is a reflection of the transmitted light beam from the object to generate a first electronic signal at the first set of photodetectors. A processor obtains a first measurement of a parameter of the object from the first electronic signal. The vehicle includes a navigation system for navigating the vehicle with respect to the object using at least the first measurement of the parameter.

Abstract: A window assembly includes a first radio frequency device disposed between a first window substrate and a second window substrate. An embedded coplanar waveguide is disposed between the first window substrate and the second window substrate, and is attached to the first radio frequency device. An exterior coplanar waveguide is disposed adjacent an exterior side surface of the first window substrate, and is disposed opposite the embedded coplanar waveguide for communicating electromagnetic waves therebetween. A printed circuit board is attached to and interconnects the exterior coplanar waveguide and a radio frequency cable connector. The radio frequency cable connector is configured for connection to a second radio frequency device. An adhesive layer bonds the printed circuit board to the exterior side surface of the first window substrate.

Abstract: A thin film, flexible, co-planar waveguide (CPW), antenna structure suitable to be mounted on vehicle glass and that has particular application for MIMO LTE applications in, for example, the 0.46-3.8 GHz frequency band. The antenna structure includes a planar antenna formed on a substrate that includes a ground plane having an elliptical cut-out slot section defined within an outer perimeter portion of the ground plane and an antenna radiating element extending into the slot from the perimeter portion.

Abstract: A processor-implemented method by a message recipient in a vehicle or on a mobile device for decoding overlapping wireless messages is provided. The method comprises: receiving a first message from a first message sender that overlaps with a second message received from a second message sender; estimating, in a first signal recovery phase, a received data symbol (d0) from the first message and a channel impulse response (h1) corresponding to a data channel between the message recipient and the second message sender; estimating, in a second signal recovery phase, a received data symbol (d0)′ from the first message and a received data symbol (d1) from the second message; and reconstructing the first message from the estimated data symbol (d0) estimated in the first signal recovery phase and estimated data symbol (d0)′ estimated during the second signal recovery phase and reconstructing the second message from the estimated data symbol (d1) estimated during the second signal recovery phase.

Abstract: A vehicle, Lidar system and method of detecting an object is disclosed. The Lidar system includes a photonic chip, and a laser integrated into the photonic chip. The laser has a front facet located at a first aperture of the photonic chip to direct a transmitted light beam into free space. A reflected light beam that is a reflection of the transmitted light beam is received at the photonic chip and a parameter of the object is determined from a comparison of the transmitted light beam and the reflected light beam. A navigation system operates the vehicle with respect to the object based on a parameter of the object.

Abstract: The present application generally relates to antennas embedded in or on glass structures. More specifically, the application teaches an apparatus extending a ground plane on an antenna proximate to a dielectric structure, such as a windshield, in order to couple a radiated wave into the dielectric structure in order to control the tilt of the radiation pattern of the antenna.

Abstract: A method and apparatus for dynamically modifying filter characteristics of a Delta-Sigma modulator to accommodate for Doppler shift. A transceiver in a wireless cellular communication system for adapt to changes in the RF carrier frequency for maintaining signal integrity by applying a pilot tone in calibration to determine a frequency shift response for a bandpass filter. During operation, the system is operative to determine a Doppler shift and to shift the bandpass filter in response.
