Abstract: A vehicle seat is provided having a track assembly to allow a seat bottom to slide in a fore-aft direction. A lock assembly is connected to the track assembly and moveable between a locked status and an unlocked status, wherein in the locked status the seat bottom is prevented from sliding, and in the unlocked status, the seat bottom is allowed to slide. A seatback is pivotally connected to the seat bottom. When the seatback is pivoted forward to a first inclined position, the seatback engages and moves the lock assembly to the unlocked status. In the unlocked status, the seat bottom is biased to slide rearward to a rear storage position. In the rear storage position, the lock assembly is moved to the locked status.

Abstract: A data prefetching method and a terminal device are provided. The CPU core cluster is configured to deliver a data access request to a first cache of the at least one level of cache, where the data access request carries a first address, and the first address is an address of data that the CPU core cluster currently needs to access in the memory. The prefetcher in the terminal device provided in embodiments of this application may generate a prefetch-from address, and load data corresponding to the generated prefetch-from address to the first cache. When needing to access the data, the CPU core cluster can read from the first cache, without a need to read from the memory. This helps increase an operating rate of the CPU core cluster.

Abstract: An anti-submarine arrangement for a vehicle seat includes an elongated member pivotably attached between opposing members of a seat bottom support structure. A leg is fixedly attached to the elongated member and pivotably attached to a structural portion of the vehicle seat. The elongated member is rotatable forward and downward relative to the structural portion of the vehicle seat. A damper arrangement is attached to the leg and to the structural portion of the vehicle seat. The damper arrangement opposes a forward and downward rotation of the elongated member.

Abstract: A track assembly includes a track and a support member connected to and configured move along the track. The support member may include an engagement portion. The engagement portion may be configured to engage the track to limit relative movement between the track and the support member in a loaded state of the track assembly. The engagement portion may be configured not to operatively engage the track or limit movement between the track and the support member in an unloaded state of the track assembly.

Abstract: The method and system disclosed herein presents a food preparation system that provides a user-friendly data collection and data annotation process that leverages crowd-sourced data to reduce the prohibitive costs associated with developing an extensive training set using dedicated cooking experiments and specialized manual annotation efforts. The food preparation system and corresponding method collect one or more data types (e.g., structured data such as temperature and weight data, and unstructured data such as images and thermal maps) and allow the collected data to be annotated by human users in order to provide information regarding the process of cooking, as well as food item identity, location, and/or outline information. A combination of image processing and user input is utilized in order to create models with food recognition and determining cooking progress.

Abstract: The present disclosure provides a cable structure, a power cord structure and an electrical device. The cable structure includes: a power cord, a shell arranged on the power cord, and an antenna arranged in the shell. Because the antenna is arranged in the shell and does not need to be exposed to the outside, it works in a good environment and can be protected from being damaged easily and, thereby guaranteeing the working reliability and stability of the antenna. Because the shell is arranged on the power cord, the electrical device does not need to be provided with additional antenna devices, thereby improving the overall appearance, convenience for carrying and the user experience. The shell is arranged on the power cord, the position of the shell can be at the middle, the front or different positions depending on requirements of the power cord, therefore satisfying different user needs.

Abstract: A cooking appliance uses machine learning models to provide better automation of the cooking process. As one example, a cooking appliance has a cook chamber in which food is placed for cooking. A camera is positioned to view an interior of the cook chamber. When food is placed inside the cook chamber, the camera captures images of the food. From the images, the machine learning model determines various attributes of the food, such as the type of food and/or the amount of food, and the cooking process is controlled accordingly. The machine learning model may be resident in the cooking appliance or it may be accessed via a network.
