摘要： Fast-acting and low-inertia actuators useable in various applications where a high force must be applied very quickly are disclosed. Power tools with detection systems configured to detect a dangerous condition between a person and a cutting tool are disclosed. In power tools, for example in a woodworking machine, a fast-acting and low-inertial actuator as disclosed herein can be used to retract a blade upon detection of a dangerous condition by a detection system. The actuator includes a charge of pressurized fluid and one or more electromagnets to selectively retain or release the pressurized fluid.

摘要： Electrical switching device are disclosed having a housing with internal component within the housing. The internal components comprise contacts configured to operate, to change the state of the switching device from a closed state, allowing current flow through the switching device to an open state which interrupts current flow through the switching device. A pyrotechnic feature is included that is configured to interact with the internal components to transition the switching device from the closed state to the open state when the pyrotechnic feature is activated. The pyrotechnic feature is configured to trigger in response to levitation between the contacts at elevated current signal flowing through the switching device.

摘要： A pneumatic actuator (4b), in particular for use in a pressure wave generator (1) comprises: a first piston surface (91) which acts counter to a gaseous working medium in a first volume (41), wherein a pressure in the first volume (41) effects an actuator force in a first direction upon the first piston surface (91); a second piston surface (92) which acts counter to the working medium in a second volume (42), wherein a pressure in the second volume (42) effects an actuator force in a second direction opposite to the first direction, upon the second piston surface (92); a throttle between the first volume (41) and the second volume (42); an inlet/outlet opening (45) of the first volume (41) for bringing the working medium into and discharging it out of, the first volume; wherein the first piston surface (91) is larger than the second piston surface (92).

摘要： A vented pressurized gas-powered actuator includes a housing having a central longitudinal axis and an inner surface. The inner surface has a constant radius between first and second planes extending perpendicular to the axis. At least one vent groove extends from the inner surface in a direction away from the axis. The at least one vent groove has a first end intersecting the first plane and a second end intersecting the second plane.

摘要： An actuator assembly includes an actuation member, a release member, and a source of pressurized gas, wherein during a normal mode of operation, the actuation member and the release member are engaged to move in unison, and wherein during an emergency mode of operation, pressurized gas automatically decouples the actuation member from the release member to move separately. In accordance with yet other aspects of the disclosure, an electro-mechanical actuator includes an electro-mechanical drive system and an integrated backup system operated by a gas generator, wherein when the backup system is activated, the electro-mechanical drive system is decoupled and the actuator moves to a predetermined position and mechanically locks in place.

摘要： A vehicular locking device includes a bore having first and second ends. A gas generating device is proximate the first end. A piston is movable along an interior of the bore. The vehicular locking device includes first and second plates. The second plate includes an aperture. Activation of the gas generating device accelerates the piston through the aperture and the second plate preventing displacement of the second plate.

摘要： A gas pressure actuator includes a cylindrical housing, a piston rod; the piston rod being accommodated inside the housing prior to driving the gas pressure actuator; a gas generator arranged at one end side in an axial direction of the housing, wherein, during driving the gas pressure actuator, the gas generator causes the piston rod to extend from the housing by generating high pressure gas; and a holding assembly that secures the gas generator to the one end side in the axial direction of the housing, wherein the holding assembly is provided with a first coupler hole for coupling the gas pressure actuator to a first hinge at a first position on an axis line of the gas pressure actuator.
