  • Publication number: 20220187626
    Abstract: The present invention provides an intelligent virtual display device including a contact lens. The contact lens has a central area thereon, a micro display disposed outside the central area, a wearable reflector disposed corresponding to the micro display and configured to receive and to reflect images of the micro display, and a controller. The controller is connected with the micro display and configured to send the control signals to the micro display so as to generate the images. The contact lens is designed for being worn on a user's eyeball. When the eyeball rotates, the micro display changes its projection direction simultaneously to match the user's visual angle.

  • Patent number: 10494727
    Abstract: A control system for an electrolytic cell includes a voltage converter converting an input voltage into a decomposition voltage, a temperature sensor generating a sensed temperature, an electric power sensor generating a sensed voltage, and a control unit storing voltage-temperature characteristics. The control unit determines a voltage that corresponds to the sensed temperature according to one of the voltage-temperature characteristics, and generates, according to a difference between the voltage thus determined and the sensed voltage, a control signal which is provided to the voltage converter such that the decomposition voltage decreases along with increase in the sensed temperature.

  • Patent number: 9723411
    Abstract: A piezoelectric speaker driving system includes a band splitter, a plurality of gain producers, an adder, a piezoelectric speaker, a sound compensator and a gain-adjusting device. The band splitter receives a first audio signal and splits the first audio signal into band signals. The gain producers gain the band signals respectively. The adder receives the gained band signals to generate a second audio signal. The piezoelectric speaker outputs a sound according to the second audio signal. The sound compensator analyzes a sound pressure level of the sound to generate a control signal. The gain-adjusting device adjusts the gains of the gain producers according to the control signal.

    Abstract: A physiological signal collection unit is for use with a physiological signal measuring apparatus to measure physiological signals from an anatomical part of a test subject, in which the anatomical part is covered with hair. The physiological signal collection unit includes a detector and a wearable member. The detector includes a circuit substrate defining a substrate-through-hole to permit hair strands to extend through, an electrical connector, and at least one signal collecting component. The wearable member is to be worn on the anatomical part of the test subject, and is formed with a through-hole having a size smaller than size of the circuit substrate. The through-hole permits the hair strands extending through the circuit substrate to extend through the wearable member.
