摘要:
The electrostatic elements already present in a vibratory gyroscope are used to simulate the Coriolis forces. An artificial electrostatic rotation signal is added to the closed-loop force rebalance system. Because the Coriolis force is at the same frequency as the artificial electrostatic force, the simulated force may be introduced into the system to perform an inertial test on MEMS vibratory gyroscopes without the use of a rotation table.

In one embodiment, a device is provided that includes:a plurality of actuators arranged into a plurality of rows and a plurality of columns; a plurality of row conductors corresponding to the plurality of rows; a plurality of column conductors corresponding to the plurality of columns; and a controller configured to select at least one of the actuators in a row by raising a voltage on the corresponding row conductor to couple each selected actuator to its corresponding column conductor.

A device can have an optical component having at least one alignment/attachment feature and a MEMS structure having a complimentary alignment/attachment feature for each alignment/attachment feature of the optical component. Each alignment/attachment feature of the optical component can mate with a corresponding alignment/attachment of the MEMS structure to align and/or attach the optical component to the MEMS structure. Thus, improved combinations of optical components and MEMS devices can be provided.
摘要:
A device may comprise an upper module cover, a lower module cover, an outer frame, and an actuator having a movable frame. The movable frame may be at least partially disposed intermediate the upper module cover and the lower module cover. A hinge flexure may interconnect the outer frame and the movable frame such that the movable frame is rotatable with respect to the outer frame. The upper module cover and/or the lower module cover may be adapted to limit a movement of the movable frame.

A lens barrel assembly for a camera is disclosed. The lens barrel assembly comprises a lens barrel, at least one optical element disposed within the lens barrel, and an actuator configured to move the optical element. The actuator can be disposed entirely or partially within the lens barrel. The actuator can be a MEMS actuator, such as a MEMS actuator that is formed at least partially of silicon. The optical element can be a lens.

An impulse actuated device for, e.g., an optical element of a digital camera, includes an elongated flexure having a first end upon which the optical element is disposed, and an opposite second end fixed so as to constrain the element to move along an arcuate, relatively long first trajectory between opposite initial and final positions, and a short-throw, high force element actuator that includes a stator and a stage supported for movement relative to the stator and along a second trajectory intersecting the first trajectory at the initial position of the element, and an apparatus for accelerating the stage along the second trajectory and against the element such that at least some of the momentum of the stage is imparted to the element and causes the element to move along the first trajectory and from the initial position to the final position.
摘要:
An apparatus includes a planar member having a first planar surface, a hollow body having first and second end openings, and a window. The planar member is configured to receive a device mounted on the first planar surface and surrounded by at least a track of a first material having a first hardness affixed to the first planar surface. The hollow body has a sharp edge at the second end along a planar section of the hollow body. The hollow body comprises a second material with a second hardness equal to or greater than the first hardness. The window encloses the hollow body first end forming an enclosure interior region configured to surround the device. The window provides the transmission of light into or out of the interior region. The hollow body second end is urged against the first material to form a hermetically sealed enclosure around the device.
摘要:
A range/speed finder can be incorporated into a personal electronic device. In one example, a personal electronic device includes an automatic focus system adapted to focus an image of an object and a processor in communication with the automatic focus system adapted to detect a distance of the object using the automatic focus system. The processor can be adapted to detect a speed of the object and/or a dimension of the object using the automatic focus system. Methods and systems for determining a distance, a dimension, and/or a speed of the object relative to the personal electronic device are also provided.
