Abstract: A wearable device for measuring blood pressure comprises a housing with through-holes formed thereon, a processing unit disposed in the housing, a display connected to the processing unit, a plurality of sensors connected to the processing unit, the sensors being configured to transmit at least one physiological signal to the processing unit via the through-holes, and a time delay structure connected between one of the through-holes and one of the sensors and configured to lengthen a path distance between the skin surface and the sensor, wherein the processing unit is configured to determine a systolic arterial pressure and a diastolic arterial pressure by the at least one physiological signal and a Moens-Korteweg (MK) function, and to control the display to display the systolic arterial pressure and the diastolic arterial pressure to be read by the user.

Abstract: Disclosed is a method for forming a crystalline protective polysilicon layer which does not create defective voids during subsequent processes so as to provide effective protection to devices underneath. In one embodiment, a method for forming a semiconductor device, includes: depositing a protective coating on a first polysilicon layer; forming an epitaxial layer on the protective coating; and depositing a second polysilicon layer over the epitaxial layer, wherein the protective coating comprises a third polysilicon layer, wherein the third polysilicon layer is deposited at a first temperature in a range of 600-700 degree Celsius, and wherein the third polysilicon layer in the protect coating is configured to protect the first polysilicon layer when the second polysilicon layer is etched.

Abstract: An IP address display device suitable for a power device is provided. The IP address display device comprises a communication interface, a display interface, and a control circuit. The control circuit is electrically coupled to the communication interface and the display interface, and is used to determine whether an IP address allocated by a DHCP server has been obtained through the communication interface. When the determination result is yes, the control circuit automatically displays the obtained IP address by the display interface for a preset time. In addition, a power distribution unit and an uninterruptible power system using the same are also provided.

Abstract: An engine starter for a reversible engine includes a drive device rotatably mounted on the reversible engine. The drive device includes a flywheel connected to a motor and a positioning seat selectively attaching the flywheel to the reversible engine. The positioning seat releases from the reversible engine when the reversible engine is started. An ignition device is adapted to be connected to the reversible engine. The ignition device includes a rotor rotated with the reversible engine. A sense member is mounted on an outer periphery of the rotor and a magnetic sensor is separately mounted in close proximity to the sense member and corresponding to the sense member. The sense member is adapted to make the magnetic sensor providing an ignition signal to a spark plug that is mounted on the reversible engine when the rotor rotates.
