An optical module is provided, including a movable portion, a fixed portion, and a circuit assembly. The movable portion is configured to connect an optical member, and is movable relative to the fixed portion. Moreover, the movable portion is movably connected to the fixed portion via the circuit assembly.

An optical element driving system is provided. The optical element driving system includes a fixed portion, a first movable portion, a second movable portion, a first driving assembly, a second driving assembly, and a connecting element. The first movable portion is used for moving relative to the fixed portion. The second movable portion is used for holding an optical element having a main axis, and is movable relative to the first movable portion. The first driving assembly is used for driving the first movable portion to move relative to the fixed portion in a first dimension. The second driving assembly is used for driving the second movable portion to move relative to the first movable portion in a second dimension. The connecting element connects the first movable portion and the second movable portion.

A driving mechanism for moving an optical element is provided, including a first fixed part, a second fixed part, a movable part, and a driving unit. The movable part is movably connected to the first and second fixed parts for holding the optical element, wherein the optical element has an optical axis. The driving unit drives the movable part to move along the optical axis relative to the first and second fixed parts.

An optical element drive mechanism is provided. The optical element drive mechanism includes an immovable part, a movable part, and a drive assembly. The movable part is connected to an optical element that includes an optical axis. The movable part is movable relative to the immovable part. The drive assembly drives the movable part to move relative to the immovable part.

Sensor systems are described that are designed to be integrated with gloves for the human hand. An array of sensors detects forces associated with action of a hand in the glove, and associated circuitry generates corresponding control information that may be used to control a wide variety of processes and devices.

The present application relates to an operating appliance for interacting with a user, including a transparent cover device, a support device with a sensor cutout, and a pressure switch, wherein the transparent cover device forms an operating area and a lower side lying opposite to the operating area and the support device is arranged on or at the lower side and the pressure switch is located and aligned within the sensor cutout in such a way that a user input by means of a finger of the user on the operating area is detectable by the pressure switch, wherein a finger indentation is provided on the operating area and arranged above the pressure switch.

A physical disturbance sensor includes a plurality of piezoresistive elements configured in a resistive bridge configuration. A signal transmitter is electrically connected to the physical disturbance sensor and configured to send an encoded signal to the piezoresistive elements of the resistive bridge configuration. A signal receiver is electrically connected to the piezoresistive elements and configured to receive a signal from the physical disturbance sensor. The received signal from the physical disturbance sensor is correlated with the sent encoded signal in determining a measure of physical disturbance.
