Abstract: The present disclosure pertains to techniques for reducing inaccuracies in context aware policies (CAP) with real-time feedforward validation in extended reality environments. In a particular aspect, a extended reality system is configured to author, by a user using the head-mounted device, a rule or policy or context aware policy (CAP) including one or more target actions and triggering context instances, capture, using one or more sensors, context history records for the user, render, by the head-mounted device, one or more validation scenes based on the rule or policy or CAP and the context history records, validate, by the user using the head-mounted device, the one or more validation scenes within an extended reality environment, and update, by the user using the head-mounted device, the rule or policy or CAP based on the validation.

Abstract: The invention relates to the field of jewelry processing, in particular to a hole positioning device for jewelry processing, which includes a main body and an operating cavity provided in the main body. A support plate is slidably disposed in the operating cavity and is located in the operating cavity. A sliding plate below the support plate, a cylinder is fixedly arranged in the sliding plate, and a through hole is formed in the cylinder, and a drilling positioning device for jewelry processing provided by the present invention can realize the ordering of jewelry. Perforating, a circulating water cooling device is installed in the equipment, which can cool the jewelry during cutting, so as to prevent the drill bit from overheating to affect the cutting effect. At the same time, the fixing device set in the equipment can easily fix the jewelry, and it automatically locates when drilling.

Abstract: An integrated magnetic flyback converter includes interleaved phases that can be connected in series for an input stage and in parallel for an output stage. An integrated magnetic core has legs with gaps that may weaken a coupling between a primary and secondary of the associated transformer. The primary and secondary of the transformer may be inversely coupled for each phase. The transformer leg gaps permit each phase to be operated with a duty cycle ratio greater than 50%. The interleaved converter has reduced output current ripple, reduced input component voltage stress, reduced magnetizing inductance, reduced magnetic component physical size and reduced common integrated magnetic core current spikes.
