    Abstract: A system includes primary and secondary devices (e.g., camera controllers that drive voice coil motors) each having respective outputs and a communication link. The primary device includes first and second hardware timers, each of which expires at a time derived from a periodic control loop trigger. At first timer expiration, the primary transmits first updated values to the secondary. At second timer expiration, primary device hardware picks up and applies second updated values to the primary device outputs. In response to receiving the first updated values from the primary device, the secondary device applies the received first updated values to its outputs. The primary/secondary device combination provide a sufficient number of total outputs that they could not individually provide and further synchronize the outputs with small skew through the timers, which are programmable to also accommodate processing of inputs (e.g., from voice coil motor sensors) to compute the outputs.

    Abstract: An optical module is provided. The optical module includes a fourth immovable part, a fourth movable part, a fourth driving assembly, a first connection element, and a fourth connection element. The fourth movable part is movable relative to the fourth immovable part. The fourth driving assembly drives the fourth movable part to move relative to the fourth immovable part. The fourth driving assembly includes a first dimension piezoelectric element for generating a first dimension driving force and a first dimension transmission element for transmitting the first dimension driving force. The first dimension piezoelectric element is connected to the first dimension transmission element via the first connection element. The first dimension transmission element is connected to the fourth immovable part via the fourth connection element. The Young's modulus of the first connection element is different from the Young's modulus of the fourth connection element.

    Abstract: A voice coil motor includes a base, a lens housing, a voice coil, a magnet, an elastic sheet, and a yoke member. The lens housing has a first margin wall, and a first protrusion and a second protrusion extend from the first margin wall. The height of the second protrusion is lower than the height of the first protrusion. The yoke member has a first wall, a connection wall, a second wall, and a side wall. The first wall, the connection wall, and the second wall together form a stepped structure. The first wall is disposed on the first protrusion, and the second wall is disposed on the second protrusion. The lens housing has a deflectable angle relative to a horizontal reference line. When the lens housing deflects to a maximum value of the deflectable angle, the second protrusion abuts against the second wall.
