The tire inflation device is at least partially integrated with a wheel hub bearing comprising a stationary outer ring and a rotatable inner ring and comprises: an engagement port extending through an axial end of the outer ring; an adapter engaged to the engagement port to form a first air passage; a second air passage disposed in the inner ring and in fluid communication with a tire; and a sealing assembly comprising first and second sealing components, the first sealing component comprising a first end abutting against the axial end and the second sealing component comprising a second end abutting against the inner ring, wherein the second sealing component is rotatably engaged to the first sealing component to form an annular air passage fluidly communicating the first air passage to the second air passage.

Abstract: A method and device for regulating a tire pressure of a vehicle and a storage medium. The method comprises: setting tire pressure modes each defining a reference tire pressure; acquiring information comprising a value of a vehicle speed and a value of the tire pressure, a weather condition, a route, a predicted road condition and an energy state of the vehicle; selecting one tire pressure mode; determining a value of the reference tire pressure; and determining a difference for regulating the tire pressure. In some of the tire pressure modes, the reference tire pressure is defined as a function of the vehicle speed and has a lower value when the vehicle speed increases within a specified range and a higher value when the vehicle speed decreases within the specified range.

Abstract: Provided are a direct time of flight (dTOF) sensing module, a terminal device, and a ranging method, to resolve a problem that in a conventional technology, a dTOF sensing module cannot adapt to different detection scenarios to some extent. Every K light sensitive units (401) of W light sensitive units (401) included in the dTOF sensing module share a first storage space. A processing control unit (403) is configured to control gating of N light sensitive units (401). The gated N light sensitive units (401) occupy the first storage space, and Q time slice bins are allocated to each gated light sensitive unit (401), so that the dTOF sensing module operates in a first mode or a second mode. The dTOF sensing module is flexibly applicable to different detection scenarios.

Abstract: A controller for a multi-phase switching power supply shuffles the sequence of the phases in response to a load transient to prevent synchronization of one or more phases with high-frequency load transients. The sequence may be shuffled by varying the frequency and/or sequence of the switching control signals to introduce a random variation in the phases.
