Abstract: A computer includes a processor and a memory, and the memory stores instructions executable by the processor to receive a plurality of radar data streams from a respective plurality of ultrawideband (UWB) radars in a passenger compartment of a vehicle, generate a combined radar data stream by averaging the radar data streams together, measure a biometric characteristic of an occupant of the passenger compartment based on the combined radar data stream, and actuate a component of the vehicle based on the biometric characteristic.

Abstract: Despite the usefulness of foundation models, they often return irrelevant or inaccurate responses to domain-specific queries, which often include technical jargon and patterns that are unique to the domain. Training data for specialized domains is not readily accessible or frequently discussed in online forums, so foundation models lack understanding in specialized domains. Moreover, while the embedding models underlying foundation models may be finetuned using annotated datasets, generating these datasets for niche and specialized domains is an extremely arduous, time-consuming, and expensive task. These issues are overcome by implementing a generative pseudo labeling (GPL) approach to creating labeled data for finetuning embedding models to recognize semantic similarities for specialized domains. In this way, the accuracy and relevance of foundation-model responses to domain-specific queries is improved.

Abstract: A power management system for a vehicle includes a power source, switching circuitry, and a first converter electrically interposing the power source and the switching circuitry. The first converter has a first power output threshold. A second converter electrically interposes the power source and the switching circuitry. The second converter has a second power output threshold lower than the first power output threshold. Control circuitry is configured to, in response to a key-off state of the vehicle, control the switching circuitry to supply power to at least one load, compare the power drawn from the second converter by the at least one load to the second power output threshold, and communicate an output to limit the power drawn from the second converter by the at least one load in response to the comparison.

Abstract: A media processing tool adds custom data to an elementary media bitstream or media container. The custom data indicates nominal range of samples of media content, but the meaning of the custom data is not defined in the codec format or media container format. For example, the custom data indicates the nominal range is full range or limited range. For playback, a media processing tool parses the custom data and determines an indication of media content type. A rendering engine performs color conversion operations whose logic changes based at least in part on the media content type. In this way, a codec format or media container format can in effect be extended to support full nominal range media content as well as limited nominal range media content, and hence preserve full or correct color fidelity, while maintaining backward compatibility and conformance with the codec format or media container format.

Abstract: A device for venting and ejection, and an injection mold for plastic injection are provided. The device includes a gas permeable layer and a gas storage chamber. The gas permeable layer is arranged at the end of a filling area in the injection mold, is made of porous metal materials used for the gas to pass through. The gas storage chamber is arranged on the side of the gas permeable layer opposite the mold cavity, and a cavity which only communicates with the pores is arranged in the gas storage chamber. During injection molding, after raw materials enter the mold cavity, gas in the mold cavity is compressed by the raw materials and passes through the gas permeable layer to achieve exhaust, to facilitate filling of the raw materials. The compressed gas layer can be stored in the cavity, and then released after the injection is completed.

Abstract: Embodiments of this disclosure can provide a system and method for calibrating extrinsic parameters of roadside sensors for autonomous driving. During operation, a portable light-detection-and-ranging (lidar) unit can be brought to a sensor-installation site comprising one or more to-be-calibrated roadside sensors, and the portable lidar unit can scan outer surfaces of the to-be-calibrated roadside sensors from different angles to generate a stream of frames. The system can align, spatially, the stream of frames based on a local reference coordinate system, superimpose the aligned frames, and segment a point cloud associated with a to-be-calibrated roadside sensor. The system can determine extrinsic parameters of the to-be-calibrated roadside sensor with respect to the local reference coordinate system based on the segmented point cloud and convert the extrinsic parameters from the local reference coordinate system to a road-based coordinate system.

Abstract: A technique for controlling access to one or more attractions is achieved using a number of access keys, each being issued to one or more users. An electronic queue management part manages a virtual queue in respect of each attraction and receives electronic requests for attraction access, each request relating to an access key and being for the users associated with it to access a particular attraction. Receipt of each request causes the respective users to be added to a corresponding virtual queue. A time at which each group of users reaches the front of the virtual queue and can access the attraction is determined. The users access the attractions by presenting an access key to an access control part, in communication with the electronic queue management part. Only a user presenting an access key at the correct time for accessing the attraction is allowed access to the attraction.

Abstract: An RA (Random Access) procedure is performed by a UE (User Equipment) in cell of a gNB (next-generation Node B) of a mobile network. The UE activates, based on first data, a primary PCell. The UE receives second data from the gNB about one or more secondary PCells for (i) configuring the one or more secondary PCells and for (ii) performing an RA procedure in the one or more secondary PCells. The UE further receives third data from the gNB, indicating which of the one or more secondary PCells is to be activated. After the UE determines that the primary PCell is switched off, it activated the indicated secondary PCell, based on the second and third data. The UE performs an RA procedure in the activated secondary PCell based on the second data.
