Abstract: Apparatus and methods are provided for UE-assisted tethering report. In one novel aspect, UE-assisted tethering report is generated with UE-assisted procedure based on latency measurement configuration. In one embodiment, the UE-assisted tethering report includes one or more elements comprising one bit to inform the activation of tethering mode, latency of packet transmission, and other side-information related to tethering path. In one embodiment, the UE-assisted procedure is inserting a measurement timestamp or recording timing of a predefined transport block (TB) of the packet. In another novel aspect, the UE performs a jitter measurement for an extended reality (XR) traffic, sends a UE-assisted information report for an end-to-end path of the XR traffic based on the jitter measurements, wherein the UE-assisted information includes one or more elements comprising jitter information and burst arrival time.

Abstract: A detachable pivoting chassis includes an accommodating base, a seat, a keyboard, a pivot module and a movable stand, and the accommodating base has an accommodating part for accommodating an electronic device, and the seat has an accommodating part for accommodating a keyboard, and the pivot module has at least two connecting elements and a pivoting element, and the connecting element is disposed on a side of the accommodating base and detachably coupled to the pivoting element, such that the accommodating base can be pivoted by the pivot module, and an end of the movable stand is pivotally coupled to an external side of the accommodating base, so that the electronic device can change its using status according to user requirements, and the detachable pivoting chassis can be combined with other electronic devices to provide the convenience of use.

Abstract: A press key structure includes a keycap, a base, and two crossed pivotal support stands. Both ends of the two support stands are abutted against the keycap and the base, and the keycap and the base includes pivot lugs for pivotally coupling axle portions at both ends of the support stands, and an inverted hook disposed at each pivot lug, and the axle portions at both ends of the support stands are prevented from sliding freely out the pivot lugs without the interference by the inverted hook. During an assembling process, the two crossed pivotal support stands are latched with the pivot lugs on a side of the base first, and then latched with the pivot lugs on a side of the keycap to achieve the fixing effect, and finally the top of the keycap is pressed gently to complete the assembling process.

Abstract: A trackball adapted to an input facility is comprised of a circuit board, a retainer and an optical holder; the retainer containing a trackball; light from a light emitting device on the circuit board being reflected through the optical holder to the trackball; range and orientation of the movement by the trackball being detected by an identification device also disposed on the circuit board to solve the data of the movement of the trackball and transmit the data to a host to control a cursor accordingly.

Abstract: A photoelectric control unit installed in a video game machine and operated to control the motion of a controlled object in the screen of a display unit of the video game machine, the photoelectric control unit including a housing, a steering column installed in the housing and rotated with a steering wheel, a torsional spring mounted on the steering column, the torsional spring having one end fixedly fastened to the steering column and an opposite end fixedly connected to a fixed spring holder inside the housing, and a photoelectric controller formed of an optical transmitter and detector assembly and a signal processing circuit board for detecting rotary motion of the steering column and outputting to the display unit of the video game machine a signal indicative of rotary motion of the steering column.
