Abstract: A vehicle hitching assistance system including a controller determining a trailer target area to a rear of the vehicle. The trailer target area is positioned within left and right lateral vehicle steering limits, defined in a lateral direction between left and right boundaries respectively spaced inwardly of the left and right lateral vehicle steering limits by one of a system perception factor or a vehicle geometry factor, and defined in a longitudinal direction between a minimum movement limit and a maximum perception limit. The controller further identifies a trailer coupler within the trailer target area and outputs a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler during movement of the vehicle.

Abstract: Apparatus and method for improving the bandwidth efficiency of delivering electronic program guide (EPG) data to consumer premises equipment (CPE). In one exemplary embodiment, electronic guide data is rendered by devices away from the CPE, shifting the executing data- and bandwidth-heavy operations away from the CPE. In particular, one or more gateways at the user's home bears the processing, memory, bandwidth load to reduce the inefficiency of delivering redundant information to CPE(s) interfacing with the gateway(s). Using guide data it receives from the cloud, the gateway produces and delivers to the CPE one or more “simple views” of the guide data, including a video stream, still image, or simple HTML or other renderable formats. As the end user interacts with the CPE, the user receives a series of the simple views, allowing the rich experience that is typically given by EPG rendered directly by the CPE.

Abstract: Aspects of the disclosure relate to arranging a pick up and drop off locations between a driverless vehicle and a passenger. As an example, a method of doing so may include receiving a request for a vehicle from a client computing device, wherein the request identifies a first location. Pre-stored map information and the first location are used to identify a recommended point according to a set of heuristics. Each heuristic of the set of heuristics has a ranking such that the recommended point corresponds to a location that satisfies at least one of the heuristics having a first rank and such that no other location satisfies any other heuristic of the set of heuristics having a higher rank than the first rank. The pre-stored map information identifying a plurality of pre-determined locations for the vehicle to stop, and the recommended point is one of the plurality of pre-determined locations.

Abstract: A radar circuit for use with a host system such as a vehicle includes a radio frequency (RF) signal generator configured to generate a predetermined RF waveform, an RF antenna connected to the RF signal generator, and an ECU which executes a method. As part of such a method, a signal generator transmits the RF waveform toward different radar target types, and receives return signatures reflected therefrom. The ECU receives the return signatures from the antenna, processes the return signatures via parallel constant false-alarm rate (CFAR) subdetectors each with defined cells under test to detect the target types as a set of detection events, merges the detection events into a merged set, and executes a control action aboard the host system responsive to the merged set. Each subdetector detects a corresponding one or more of the radar target types via corresponding detection parameters.

Abstract: A password-less authentication system and method include registering a contactless card of a client with an application service and binding the contactless card to one or more client devices. The contactless card advantageously stores a username and a dynamic password. Accesses by the client to the application service may be made using any client device, and authentication of the accesses may be performed by any client device that includes a contactless card interface and can retrieve the username and dynamic password pair from the contactless card. By storing the username on the card, rather than requiring user input, application security improved because access to and knowledge of login credentials is limited. In addition, the use of a dynamic password reduces the potential of malicious access.

Abstract: A method and system for using steganographically-encoded time information as a basis to control when a client carries out a content-related action. The client processes for presentation one or more linear media streams, each defining a respective time sequence of frames of media content, and at least one of the streams being steganographically encoded with at least one watermark at a respective time-point within the stream, the watermark encoding a timestamp of the respective time-point within the stream according to a server clock. The client extracts the timestamp from the watermark and computes a time offset based on a difference between the extracted timestamp and a current time according to a client clock. And the client uses the computed time offset as a basis to determine when the client should carry out a content-related action in a given one of the one or more linear media streams.
