Abstract: An electrothermal module includes a first conductive layer, a second conductive layer, and a heat generating layer. The first conductive layer and the second conductive layer respectively include silver metal. The heat generating layer has a first portion, the first portion is disposed between the first conductive layer and the second conductive layer to form an electrothermal conversion portion of the electrothermal module, and the heat generating layer includes a conductive carbon material.

Abstract: A light emission apparatus includes a laser diode configured to emit a light; a laser driver electrically coupled to the laser diode, the laser driver being configured to drive the laser diode to generate the light; and an optical module arranged to receive the light emitted by the laser diode, the optical module comprising at least one optical element and being configured to adjust the light and emits a transmitting light; wherein the transmitting light emits from the optical module with an illumination angle and the optical module adjusts the light to vary the illumination angle.

Abstract: An uninterruptible power apparatus is coupled between a power grid and a load. The uninterruptible power apparatus includes a bypass path, a power conversion module, and a control module. The bypass path is coupled to the power grid through a grid terminal, and coupled to the load through a load terminal. The control module turns off a first thyristor and a second thyristor by injecting a second voltage into the load terminal during a forced commutation period. The control module calculates a magnetic flux offset amount based on an error amount between the second voltage and a voltage command, and provides a compensation command in response to the magnetic flux offset amount. The control module controls the DC/AC conversion circuit to provide a third voltage to the load terminal based on the compensation command and the voltage command.

Abstract: A wireless tire pressure monitoring system with interactive multiple frequency channel includes a controlling host module and multiple tire detection units. The controlling host module includes a first CPU, a key unit, a display unit, a low-frequency wireless transmitter, and a high-frequency wireless receiver. The tire detection units are separately provided on tires of a vehicle and each include a second CPU, a tire information detecting device, a low-frequency wireless receiver, and a high-frequency wireless transmitter. A default standard value may be set via the key unit. The low-frequency wireless transmitter transmits a low-frequency signal to each of the low-frequency wireless receivers for requesting the tire detection units to transmit current tire information, which is then sent via a high-frequency signal transmitted by the high-frequency wireless transmitter to the high-frequency wireless receiver.
