    摘要: A pyroelectric sensing device includes two pyroelectric sensors and a driving mechanism. The driving mechanism is used for driving the two pyroelectric sensors to shift. When a human body stays motionless in an environment, the two pyroelectric sensors driven by the driving mechanism will shift with respect to the human body, such that the two pyroelectric sensors generate different sensing voltages due to the infrared radiation emitted by the human body. Accordingly, the motionless human body will be detected.

    摘要: An EUV optical apparatus includes a number of adjustable mirrors (22x) on mirror bodies (120). Each mirror body is supported on an actuator (100x) comprising a moving part (132, 134, 136) and a fixed casing part (128, 130). The actuator provides a resilient support (140, 142) for the mirror body so that it is tiltable with two degrees relative to the casing. An electromagnetic motor (166, 170-178) applies first part, under the influence of an applied motive force, the resilient mounting being arranged to provide a biasing force that resists said motive force. A magnetic coupling (102, 104a, 104b) is arranged between the moving and fixed parts so as to provide a counter-biasing force. The counter-biasing force partly opposes said biasing force and thereby reduces the motive force required to effect a given displacement. The actuator can thus be made with reduced size, weight and heat dissipation.

    摘要: A magnetic actuator has a static part and a dynamic part concentrically arranged therein. The static part comprises two permanent magnets and the dynamic part comprises two further permanent magnets. The magnet is oppositely oriented to the further magnets. The magnets are tuned to each other in such a way that the gravity on the dynamic part is compensated by the magnetic force on the dynamic part. The static part further includes a coil with which an additional magnetic field can be generated by which the actuation force can be adapted.

    摘要: A long-proportional-stroke force motor which outputs force proportional to the exciting current. The motor has a magnetic circuit wherein a non-magnetic spacer is positioned axially between a magnetic guide and a magnetic sleeve. An armature moves within a central opening defined by the guide, the spacer and the sleeve. An end portion of the guide, adjacent to the spacer, has a sectional profile through a stepped surface facing radially outward and the corners of the steps define a curve which satisfies the following expressions: ⅆ Y ⅆ X > 0 , ⁢ ⅆ 2 ⁢ Y ⅆ X 2 > 0 , where X is a coordinate on an X-axis corresponding to a central axis of the guide; wherein the armature is moved in a direction along the X-axis by application of exciting current to a coil surrounding the guide, spacer and sleeve; and Y is a coordinate on an axis orthogonal to the X-axis.

    摘要: An actuator for rotating (or moving) a rotor (or a moving member) according to the current flowing through an electromagnetic coil. Magnetic energy of magnetomotive force induced in the electromagnetic coil when energized is stored in an air gap and a sub-air gap provided in a magnetic path. The rotor (or the moving member) comes to rest at a position where the stored magnetic energy becomes the smallest. The stored magnetic energy serves as a source of counterforce and functions in the same way as a spring.

The movable unit is connected to a stopper of the outer pipe at one end of the outer movable unit and to the linear output unit at the other end. The magnetic flux generating unit generates first magnetic fluxes. The movable unit has elasticity, and expands or contracts based on action of the first magnetic fluxes and the elasticity. The linear output unit linearly moves in response to the expansion or contraction of the movable unit.

    摘要: A new class of actuators and mechanisms use opposing repulsive magnetic forces. The repulsive forces are typically generated between a stationary magnet and a moving magnet, where the moving magnet is coupled to the mechanism output member. The mechanisms are generally configured such that the repulsive force from one electromagnet is opposed by a repulsive force from another electromagnet, where the opposing forces are simultaneously applied to the mechanism's output member. This configuration is similar in certain aspects to the way biological flexor and extensor muscles are configured in a musculoskeletal system. The opposing configuration allows for open loop control of position and stiffness. The actuator mechanism may have both rotary and linear motion output, and may have either a single degree of freedom or multiple degrees of freedom. Permanent magnets can be used to create a baseline repulsive force without electric power, and electromagnets can modulate the repulsive force magnitude. The actuator can provide high fidelity motion and force output, and is well suited for human interface devices, such as force feedback joysticks. Other applications include adjustable stiffness devices, and high bandwidth mechanisms.

    摘要: A novel duel directional electromagnetic actuator includes a case, a core, an electrical current conductive coil and a field coil. The case includes a first case end, a second case end, and an interior wall extending between the first and second case ends. A chamber is defined by the interior wall. An electrical current conductive coil is disposed in the chamber coextensively adjacent the interior wall. The conductive coil has a first coil end disposed proximate the first case end, a second coil end disposed proximate the second case end, and a midpoint. The core has a first core end, a second core end, and an exterior wall extending between the first and second core ends. The exterior wall has a first region adjacent the first core end and a second region spaced from the first region and adjacent the second core end. The core is moveably received in the chamber with motion of the core occurring between the first and second case ends such that said first region traverses the conductive coil between the first coil end and the midpoint and the second region traverses the conductive coil between the second coil end and the midpoint. The conductive coil and the exterior wall are in a facing relationship with respect to each other. The field coil is in a spaced relationship to the conductive coil so that magnetic flux across the conductive coil between the first region and the interior wall is in a first direction and magnetic flux across the conductive coil between the second region and the interior wall is in an opposite direction. The field coil is arranged so that an electrical current in the conductive coil between the first coil end and the midpoint flows in an opposite direction than the current between the second coil end and the midpoint, whereby the flux current cross products of the flux in the first direction with the current and the flux current cross products of the flux in the second direction and said current are additive.
