Abstract: The present invention relates to an induction trash can circuit standby power-saving method. An induction trash can circuit is provided. The induction trash can circuit comprises an active infrared sensor, a microcontroller, a driving circuit and a motor for controlling the opening and closing of a lid. The power-saving method is achieved through the following manners that: in a standby state, the microcontroller controls the active infrared sensor to emit an infrared pulse signal to an induction area; if no obstacle exit in the induction area, the active infrared sensor outputs no signals, the program of the microcontroller immediately enters a sleep state; after the program of the microcontroller sleeps for a period of time, a watchdog timer in the microcontroller wakes up the microcomputer controller to make the microcontroller re-enter a working state; and if the microcontroller is in a standby state, the above process is repeated.

Abstract: An electric brush powered by mains electricity includes a power converter, an upper housing, a lower housing, a push button switch, an electric motor, a speed reducer, an output rotation shaft, an adapter, a brush head and a seal ring.

Connection relations there-between include the oscillating circuit coupled to the controller, the converter coupled to the controller and CCFL, and the protective circuit coupled to the CCFL and oscillating circuit. The controller is activated in response to first input voltage, and configured to output a control signal in response to second input voltage. The oscillating circuit is able to adjust oscillating frequency of operation clock for the controller. The converter is controlled with the control signal, and configured to convert third input voltage into an output voltage. This output voltage is for driving the CCFL. The protective circuit disables the oscillating circuit when the CCFL remains at a state such as open circuit or short circuit. A lamp-tube module and a lamp-tube driving system for the lamp-tube driving device are further disclosed.

Abstract: The size of particles is detected accurately and at low cost even when there are few microparticles as impurities included in a liquid. Provided is a method of detecting a size of particles in a liquid by detecting diffraction fringes appearing due to the particles in the liquid by a light detection portion. Diffraction fringes are detected by a first light detection portion and a second light detection portion that are separated along the flow direction of the liquid. A peak time difference (T2) that is a difference between times at which peak values appear in a detection signal from the first and second light detection portion is measured, and an area (SQ) based on the waveform of the detection signal is measured. The sizes of the particles included in the liquid are detected based on the peak time differences (T2) and the areas (SQ) that were measured.

Abstract: The present invention provides a key switch with an exhaust structure, which includes a keycap having a top surface and an inner surface with a cavity and an elastic member. The elastic member includes a protrusion and an elastic body. The protrusion is coupled with the inner surface of the keycap. A gas channel is formed between the cavity of the keycap and the protrusion of the elastic member. When an external force is applied to the top surface of the keycap to compress the elastic body, the gas within the elastic member can be exhausted through the gas channel of the elastic member.

Abstract: A rotatable locking member is located between a plunger of a switch and a contact part that is configured as a slide, with the rib-type locking elements of the locking member engaging corresponding groove-type locking elements of the plunger. The contact part is fixed in the axial direction on the locking member, but is mounted so that it can be rotated in relation to the member. In an initial position of the plunger, an anti-torsion device, which can be released by an unlocking action, secures the locking member against torsion. This allows both the plunger and the contact part to be accommodated by the housing of the switch so that they can be axially displaced, but are resistant to torsion, thus increasing the adjustment reliability and preventing undesired torsion of the locking member before the start of the adjustment process.

The shell has a front surface, a back surface, and a bottom surface. The keyboard-holding device has a first elongate member, a pivot, and a locking mechanism. The first elongate member has a first end, a second end, and a pivot located between the first and second ends. The locking mechanism is attached with respect to the second end for unlockably locking the first elongate member to a holder, said holder fixedly attachable to the support. A fulcrum is rotatably attached with respect to the pivot and fixedly attached with respect to the shell. A spring mechanism provides a restoring force tending to maintain the locking mechanism in locked engagement with the holder, but is manipulable to unlock the shell from the holder.

Abstract: An ionizer control system uses a short-range wireless communication means implemented with, for example, Bluetooth (registered trademark) between an ionizer, an ion monitor, and a server, and that automatically evaluates the performance of the ionizer and the ion monitor, monitors the operational state thereof, and adjusts the ion balance. The ionizer control system includes an ionizer, an ion monitor, and a server, each having communication means that complies with a short-distance wireless communication standard, such as Bluetooth. For example, ionizer control data, including the magnitude and time of a positive or negative voltage applied to emitters, and operational state data are transmitted and received between the server and the ionizer. For example, ion monitor control data, such as a charge start voltage applied to a charge plate and a stop voltage, and operational state data are transmitted and received between the server and the ion monitor.

Abstract: A small sized connector for connecting wires to an electrical component, such as a printed circuit board. The connector includes a connector frame, and a latch that is hingedly connected to the connector frame. The latch has a raised portion at one end thereof, whereby, when the connector frame is fitted within an opening of a housing that holds the printed circuit board, the latch is pressed downwards to be fitted within the opening, and then the raised portion of the latch pops into a slot of the housing to thereby lock the connector in place within the housing. The connector can be easily de-coupled from the housing by a user pressing his or her fingertip against the raised portion of the latch, while pulling the connector out of the opening at the same time.
