  • Patent number: 11947745
    Abstract: A handwriting data processing method is applied to a pen display having wireless communication function and a data processing device. The handwriting data processing method includes the steps of: the data processing device obtaining a handwriting data from the pen display in a wireless communication manner; the data processing device generating a compressed screen image and transmitting the data of the compressed screen image and the handwriting data, which is not compressed, to the pen display in the wireless communication manner; the pen display uncompressing the data of the compressed screen image and overlapping the uncompressed screen image and the handwriting data to form a complete screen image and displaying the complete screen image. By the handwriting processing method, the machine time of the processor of the pen display is effectively lowered, significantly reducing the delay phenomenon of the displayed handwriting.

  • Patent number: 11668378
    Abstract: A linear transmission device includes a screw, a moving member, a return element, and a sensor. The moving member is set in the screw to form a load path therebetween. The return element is set in the moving member and has a return path connected to the load path. The return path and the load path constitute a circulating path for balls to run. The moving member has an internal thread with an ineffective thread section. The moving member has a receiving groove adjacent to the ineffective thread section. The sensor is embedded in the receiving groove of the moving member without affecting the operation of the balls. Thus, the linear transmission device of the present invention can solve the problem of the sensor protruding from the moving member, so that the configuration of the surrounding space and the stroke of the moving member will not be affected.

  • Patent number: 11307406
    Abstract: A Cascaded Mirror Array optical scanning system applies an array of reflectors, with each reflector (called array reflector for convenience) movable between discretized angular positions and independently switched by digitized electrical signals, to process a light beam by cascaded reflections to generate desired deflection angle of the beam. The precision of the discretized angular positions of each array reflector is maintained by a support structure, which supports the reflector while allowing it to rotate or tilt, and a set of positioning limiting structure, which limits the allowable angular position of the array reflector between a finite number of angular positions corresponding to the discretized angular positions.

  • Patent number: 10912710
    Abstract: A microbubble device controller includes a box, and a first water pipe, a gas pipe and a bypass pipe installed in the box. The first water pipe is connected to a pump and has a first electromagnetic control valve to open or close the first water pipe. The gas pipe is connected to a gas source and the pump, and has a second electromagnetic control valve to open or close the gas pipe. The bypass pipe is connected to the first water pipe and has a pressure switch in telecommunication connection with the second electromagnetic control valve. The first electromagnetic control valve controls the first water pipe to be in the high flow state or a closed state to affect the bypass pipe. When the bypass pipe is in a high pressure state, the second electromagnetic control valve opens the gas pipe, or closes the gas pipe otherwise.
