Abstract: A method for intermittently discharging an inverter in an energy storage apparatus and an energy storage apparatus using the method are disclosed. The method includes a protection step; and an intermittent discharge step, which includes having a battery management system detect a charge level of a capacitor and send it to a control unit, and when the charge level is below an activation threshold, having the control unit control a battery pack to perform a first discharge procedure to charge the capacitor for at least two times intermittently until the charge level reaches the activation threshold, thereby providing fast charge for the capacitor.

Abstract: The present application discloses an inertial sensor comprising a proof mass, an anchor, a flexible member and several sensing electrodes. The anchor is positioned on one side of the sensing, mass block in a first axis.

Abstract: A microelectromechanical apparatus includes a substrate, a light diffuser device, a plurality of actuator devices, and a controller. The light diffuser device is disposed on the substrate. The actuator devices surround the substrate and are coupled to the substrate. The controller is coupled to the actuator devices. The controller applies a voltage to at least one of the actuator devices to drive the substrate and to control the light diffuser device to actuate according to a reference axis perpendicular to the light diffuser device. A projection apparatus is also provided. In the disclosure, a motion pattern and motion complexity of the light diffuser device may be enhanced. Enhancement of the movement pattern and movement complexity may lead to a significant increase in a speckle pattern contrast ratio, such that the projection apparatus may provide favorable image quality.
