Abstract: The present disclosure is applicable to a field of laser radar technology and provides a resonance module, a silicon-based external cavity chip, a laser, and a laser radar. The resonance module includes multiple main resonators and at least one auxiliary resonator, both of the main resonators and the auxiliary resonator are tunable micro-ring resonators; the multiple main resonators are cascaded in sequence through a connecting module to form a cascaded structure, and a vernier effect can be formed between two adjacent main resonators; when an auxiliary resonator is provided for matching the main resonator, coupling of the main resonator and the auxiliary resonator that are provided in a matching manner expands a free spectrum range of the main resonator. The tunable range of lasers applied to the laser radar and improve the scanning angle of the laser radar can be expanded.

Abstract: An exercise recommendation system determines a current capability of a user. The exercise recommendation system accesses an exercise history for a user. The exercise history comprises an exercise performed by the user and a capability of the user each time the user performed the exercise. The exercise recommendation system partitions the exercise history into a plurality of time periods, and, for each time period, computes an aggregate capability of the user for the exercise during the time period. The exercise recommendation system calculates a moving average capability of the user for the exercise based on the aggregate capabilities and determines a current capability of the user for the exercise based on the moving average capability. The current capability of the user may be discounted at least in part based on how recently the user performed the exercise.

Abstract: An exercise recommendation system determines workout plans for users. The exercise recommendation system trains a machine-learned model configured to rank a set of exercises, and the ranking of exercises can be modified based on feedback from a user, for instance requesting that an exercise be recommended more frequently, less frequently, or never. The exercise recommendation system can also implement a machine-learned model configured to predict a measure of strength for the user, and can, in response to determining that the measure of strength of the user has decreased or plateaued over time, modify a workout for a user based on a muscle or muscle group associated with the measure of strength. Likewise, the exercise recommendation system can modify a workout in response to a predicted measure of strength being less than an actual measure of strength, for instance to include exercises targeting muscles associated with the measure of strength.

Abstract: The present disclosure relates to a zinc-based alloy coating for steel strip through a continuous galvanizing process. This zinc-based alloy coating provides the steel with cathodic protection before and after the steel is press hardened processing at a high austenitization temperature up to 950° C. The zinc-based alloy coating also reduces or eliminates the susceptibility to liquid metal embrittlement during or after welding for various types of non-press hardenable advanced ultra high-strength steels. The zinc-based alloy comprises at least one element selected from manganese (Mn) and/or antimony (Sb).

Abstract: A client terminal starts an image capture apparatus at a first terminal device when the client terminal receives a multi-display interaction request, to capture an image at a target display interface at a second terminal device. The client terminal determines a target event and target material information correlated with the target event. The target event is displayed at the second terminal device. The client terminal provides the target material information and corresponding animation effects with the image captured by the image capture apparatus. The corresponding animation effects animate a process of the target material information leaving the display at the second terminal device and entering a display of the first terminal. The techniques of the present disclosure make the interaction process more realistic and improve user engagements.
