Patent
Delta Electronics Inc | Date: 2016-02-03

A color wheel rotation speed detecting module is disclosed and includes a color wheel, a motor, a rotation speed detector and a processor. The color wheel includes a first segment and at least one second segment. The motor drives the color wheel to rotate. The rotation speed detector includes an emitter and a receiver. The emitter outputs a light signal to the first segment or the second segment of the color wheel when the color wheel is rotated. When the receiver receives the light signal reflected from the second segment, the receiver outputs a detecting signal correspondingly. When the light signal passes through the first segment and the receiver fails to receive the light signal, the receiver interrupts the output of the detecting signal. The processor receives the detecting signal from the receiver, and obtains the rotating speed of the color wheel according to the detecting signal varied with time.

A power system including power devices connected in parallel and an allocation bus is provided. Each power devices includes an allocation signal pin, a power unit and a control unit. The control unit controls a logic level of the allocation signal pin based on an operation status of the power unit. The AND logic operation performed on the logic level of the allocation signal pin of each of the power devices results in the logic level of the allocation bus. One of the power devices is set to a master mode through a first arbitration. The other power devices monitor the operation status of each other and a status of the allocation bus. Through a second arbitration, one of the power devices under a first operation status is set to a standby mode.
