Abstract:
The invention discloses a clamping activation method, applicable to an electric clamping device with wireless charging, the electric clamping device comprising a body and a wireless charging module, a control unit, and an electric clamping assembly, all disposed inside the body. The clamping activation method comprises: the control unit receiving a signal generated by the wireless charging module; the control unit activating the electric clamping assembly to clamp the electronic device according to the signal; and the control unit activating the wireless charging module to charge the electronic device. As such, the electric clamping device can automatically clamp the electronic device without installing additional sensing elements or switches.
Abstract:
The disclosure provides a wireless charging alignment method and system, the system comprising an electronic device and a wireless charging device, the electronic device having a display screen capable of displaying at least an marking symbol, the wireless charging device having a placement surface, the wireless charging device being disposed with at least a wireless charging module inside the placement surface, and the wireless charging device further comprising at least a corresponding symbol; the alignment method of the present invention is, in the process of placing the electronic device on the placement surface, to align the marking symbol to the corresponding symbol is aligned with the corresponding symbol, thereby quickly and accurately completing the alignment of the wireless charging, and a better subsequent charging performance can be performed.
Abstract:
An electronic device includes a main body, a mounting device, and a supporting device. The mounting device attaches to the main body, and includes a mounting member, a bracket, and a latch. The bracket is mounted to the mounting member; the latch includes a securing section, and is slidably mounted to the bracket. The supporting device includes a retaining tab to engage the securing section. The supporting device is to be removed from the mounting device when the latch slides on the bracket to detach the securing section from the retaining tab.
Abstract:
A time domain symbol timing synchronization circuit is disclosed, which comprises: an autocorrelation function calculator for calculating cyclic prefix autocorrelation functions and an offset time estimator for searching peak positions of cyclic prefix autocorrelation functions to indicate symbol boundary of received communication symbols. The offset time estimator compares a current peak position and a previous peak position. If (a) the difference of the positions is larger than a threshold and (b) the current peak is smaller than a reference average peak, the current peak is determined as false; the offset time estimator weeds out and replaces the current peak position by the previous peak position; and the current peak is not introduced in the reference average peak calculation.
Abstract:
A chime bar assembly includes a hollow body with a resonation space defined therein and a top opening is defined in a top of the hollow body. A metal plate is located above the top opening and supported by two rubber plates. A hitting device is connected to the rear end of the hollow body and includes a case which includes lugs to which a pivotal end of a rod is pivotably connected. An operation unit is connected to the case and pushes the pivotal end of the rod so that the sphere is lowered to hit the metal plate.
Abstract:
A cable grounding clamp (10) includes a first grounding sheet (11), a second grounding sheet (12) and a connecting portion (13) connecting the first and the second grounding sheets. The first and the second grounding sheets respectively define a first and a second circular openings (110, 120) in the centers thereof. The connecting portion forms a passage (14) for receiving a cable (230). After the cable protrudes through the passage of the cable grounding clamp, a bolt (16) protrudes through the first and the second circular openings to engage with a printed circuit board (25). The connecting portion defines a soldering slot (130) therein, which facilitates the soldering process between the cable grounding clamp and metal braiding of the cable.
Abstract:
A case (1) includes a case body consisting of a top cover (10) and a bottom cover (20), a printed circuit board module (PCB module, 40) and a shielding member (50). The case body defines a receiving space (60) for receiving a portable storage peripheral equipment. The PCB module is received in the receiving space and comprising a printed circuit board (42) and an electrical connector (44) mounted on the printed circuit board. The shielding member is attached to an inner surface of the top cover and electrically connects with a grounding circuit trace of the printed circuit board. A copper foil (21) is attached on an inner surface of the bottom cover aligning with the PCB module and electrically connects with a resilient arm (56) of the shielding. The case has an improved shielding effect for effectively eliminating noise.
