Abstract: A mouse includes the main body and the inertial roller module. The inertial roller module is installed in the main body. The inertial roller module includes a supporting bracket, a roller, a gear assembly and an encoding element. The roller is pivotally coupled to the supporting bracket. The gear assembly includes a first gear and a second gear. The first gear is connected with the roller. The first gear and the second gear are engaged with each other. The number of teeth in the first gear is larger than the number of teeth in the second gear. The encoding element is connected with the roller. Consequently, the time period of rotating the roller is increased.

Abstract: A mouse device includes a casing, a top cover, an adjusting module and a pressing part. The casing is covered by the top cover. The top cover is movable relative to the casing. The top cover includes a saw-toothed plate. The saw-toothed plate is inserted into an inner portion of the casing and contacted with the adjusting module. The pressing part is connected with the adjusting module. When the pressing part is pressed to trigger the adjusting module, the saw-toothed plate is pushed by the adjusting module and the top cover is moved form a first position to a second position. Consequently, a shape of the mouse device is changed. The shape of the mouse device is changeable according to the size of the user's palm.

Abstract: A push-type discharge assembly of a blood pressure monitor includes a valve base, a spring, a driven element, a restricting element, and a pressing element. The valve base is provided with an accommodating trough and an intake pipe. The spring is disposed in the accommodating trough. The driven element abuts against one end of the spring. The driven element is formed with a protrusion. The restricting element covers the accommodating trough. The restricting element has a central through-hole and is formed with a restricting notch. The pressing element passes through the central through-hole. The pressing element has a sealing body and a driving portion disposed on a lower edge of the sealing body to drive the driven element. When the pressing element is pressed downwards, the sealing body moves downwards to form a discharge channel between the pressing element and the central through-hole.

Abstract: A coiling blood pressure cuff for winding and compressing a testing position of a human body includes a strip-shaped body, an inflatable bladder, and a flexible elastic plate. The inflatable bladder is installed to the strip-shaped body, and the flexible elastic plate is attached onto the strip-shaped body and along the lengthwise direction of strip-shaped body. If an external force is exerted onto the flexible elastic plate to curl and deform the flexible elastic plate, the flexible elastic plate will be curled and contracted elastically and automatically to drive the strip-shaped body to be wound and positioned at the testing position, so as to provide an easy operation and a quick positioning.

Abstract: A battery management system includes a flash memory chip having a smart battery management program and a microprocessor. An interface model (I/F module) is installed in the microprocessor as a bridge between the flash chip and the microprocessor. The I/F module includes a data register and an address register as a data buffer and address buffer, respectively, between the CPU and the flash chip. The I/F module also includes a logic control circuit to generate signals for the flash chip to read and program.
