Abstract:
A micro drive assembly may comprise a substrate, a micro shall oriented in-plane with the substrate and at least one micro bearing to support rotation of the micro shaft. The micro shaft and micro bearing may be in or less than the micrometer domain.
Abstract:
A micro rotary machine may include a micro actuator and a micro shaft coupled to the micro actuator. The micro shaft comprises a horizontal shaft and is operable to be rotated by the micro actuator. A micro tool is coupled to the micro shaft and is operable to perform work in response to motion of the micro shaft.
Abstract:
A MEMS (micro electro mechanical system) actuator with discretely controlled multiple motions comprises bottom layer, stepper plate, support, and motion plate. The multiple motion of the motion plate is generated by the electrostatically actuated stepper plates and geometrically predetermined supports. By introducing the MEMS actuator with discretely controlled multiple motions, simple motion control can be achieved by digital controlling and only single voltage is needed for motion control of the motion plate.
Abstract:
A micro device may comprise a substrate, a first micro structure coupled to the substrate, a second micro structure coupled to the substrate, and port configured to receive an input. The first micro structure is configured to move into engagement with the second micro structure in response to the input.
Abstract:
An apparatus (1) that is capable of a first stable configuration and a second stable configuration is disclosed. The bistable mechanism (10) has a leg (30, 32) that is coupled on one end by a base member (22, 24) and on the other end by a shuttle (20). The leg (30, 32) stores potential energy as it is deflected. The potential energy stored in the leg (30, 32) has a maximum potential energy position with a low potential energy position on either side of the maximum. An apparatus and method are also disclosed for a latching mechanism (910) and the associated method. The latching mechanism (910) is comprised of a grasping member (932), a lock slider (928), and a detent slider (916). These three members (916, 928, 932) operate together to induce a locked configuration and an unlocked configuration by actuating the lock slider (928) in a single direction.

Abstract:
Methods and systems for micro transmissions for a micro machine may comprise an input shaft assembly coupled to a micro actuator, an output shaft assembly coupled to a micro shaft, and one or more power conversion elements operable to convert a first type of movement from the micro actuator into a second, disparate type of movement for the micro shaft.
Abstract:
A space curve mesh driving pair and a polyhedral space curve mesh transmission are disclosed. Said space curve mesh driving pair consists of a driving wheel and a driven wheel. Axes of the driving wheel and the driven wheel are intersected at an angle of 0°˜180°, and power transmission is realized by continuous mesh between the driving tines and the driven tines; a number of driving tines are provided on said driving wheel, and a number of driven tines are provided on the driven wheel; the driving tines are uniformly arranged on an end face of a cylinder of the driving wheel, and the driven tines are uniformly arranged on the circumference of a cylindrical surface of the driven wheel. Said polyhedral space curve mesh transmission consists of an above-mentioned space curve mesh driving pair. Motion is input from an input end, and is passed through a number of pace curve mesh driving pairs to realize the speed change, then is output from one or more output ends. Wherein, the space curve mesh driving pair is the core of the transmission. The invention has the advantages of compact structure, small size, light weight, stable transmission and flexible operation, and can be widely used in micro-mechanism field.
