Abstract:
An electric bath massage brush includes a hand-sized casing, a vibrating device and a control circuit device. The casing defines a massage surface at one side. The vibrating device is disposed within the casing and configured for imparting vibration and motion to the massage surface of the casing. Specifically, the vibrating device is disposed within the casing and includes a motor and an eccentric cam. The eccentric cam is connected to one end of a drive shaft of the motor for vibrating the massage surface upon rotation of the drive shaft. The control circuit device is also disposed within the casing and has a control circuit electrically coupled to the motor of the vibrating device for control the rotation of the drive shaft of the motor.

Abstract:
The present invention provides a pressure gauge for measuring a pressure of a source. The pressure gauge includes a case, a flexible film, a magnetic device, a coil, a processor, and a screen. The case has a bore connecting the source. The coil is provided in the case. The flexible film is provided on an inner side of the case to cover the bore that the flexible film is expandable by the pressure of the source. The magnetic device is received in the case to be moved relative to the coil by the flexible film. The movement of the magnetic device causes the coil to generate an induced electromotive force, and the processor may find the gas pressure according to the induced electromotive force, and show it on the screen.

Abstract:
The present invention discloses a visualized plasmon resonance biodetector, which utilizes the surface plasmon resonance to detect a plurality of biochemical molecules, and which comprises a substrate, a silver-gold dual-layer structure, and a visible light source. The silver-gold dual-layer structure is formed on the substrate. In a test, a biochemical molecule combines with the silver-gold dual-layer structure, and the visible light source emits a visible light to illuminate the substrate. Thus, the silver-gold dual-layer structure on the substrate generates surface plasmon resonance and a reflected light. The user can use his naked eyes to discriminate the reflected lights and learn the component and concentration of the biochemical molecule. Therefore, the present invention can provide a low-cost and easy-to-operate detection instrument for biotests.
