摘要： An electromagnetically actuated valve (10) includes an upper electromagnetic element (24) and a lower electromagnetic element (26) in a mirrored and facing relationship to each other. The electromagnetic elements (24, 26) define a central channel (20) that surrounds a vertical axis (22). The valve further includes an armature element (16) that is disposed intermediate the upper and lower electromagnetic elements (24, 26). The armature element (16) is pivotally mounted to an armature shaft (32). The armature shaft (32) is perpendicular to the vertical axis (22). The valve further includes a coil (14) disposed within the central channel (20) of each of the electromagnetic elements (24, 26).

摘要： A thin film actuated mirror for an actuated mirror array (10) includes a pedestal (14) and at least one piezoelectric structure (12) cantilevered from the pedestal. The piezoelectric structure includes a layer of piezoelectric material (18) having two opposing surfaces (24, 26). Each of two metal electrodes (20, 22) are mounted on a respective one of the opposing surfaces of the piezoelectric material layer. An electrical signal is applied across the piezoelectric material, between the electrodes, causing deformation of the piezoelectric material. The thin film actuated mirror further includes a mirror surface (32) interconnected to the piezoelectric material layer such that the mirror surface deforms in response to the deformation of the piezoelectric material layer.

摘要： A thin film actuated mirror is disclosed having a substrate (16), a deformable structure (12) mounted to the substrate (16), and a mirror surface (17) interconnected to the deformable structure such that the mirror surface tilts in response to the deformation of the deformable material layer. The deformation occurs due to the effective strain gradient across the monomorph thickness which is accomplished by varying the electric field across the thickness or the strain parameter across the thickness. The deformable structure (12) includes an active material layer (18) fabricated from a semi-conductive ferroelectric ceramic material and two metal electrodes, each of the electrodes being mounted on opposing surfaces of the active material layer (18), wherein an electrical signal applied across the active material layer (18) between the electrodes causes deformation of the active material layer (18). Alternatively, the active material layer (18) may be fabricated from two layers, an upper layer (36) of an active piezoelectric material and a lower layer (38) of an inactive material.

摘要： A compact staggered electromagnetically actuated valve assembly (70) includes a first electromagnetic actuator (72) defining an upper horizontal surface (78) and an outer circumference (80) and a second electromagnetic actuator (74) defining a vertical axis (82) and a lower horizontal surface (84). The second actuator lower horizontal surface is located vertically above the first actuator upper horizontal surface and the second actuator vertical axis is disposed outside of the first actuator outer circumference. An electromagnetic actuator (10) for a valve having a valve stem (22) exhibiting thermal expansion is further disclosed. The actuated valve includes an electromagnet (12), valve seating springs (38) and an armature element (16). The seating springs and valve stem have a substantially equal degree of thermal expansion. The valve may further include an armature element adjustement member (52) to axially displace the armature element (16) relative to a normal biased spaced apart first position distal from the electromagnet when the electromagnet is not energized.

摘要： A multifunction amplifier device (68) for matching an audio signal from an audio signal source (18a-18d), such as a video game, stereo or movie, to a predetermined frequency of a transducer (12) is disclosed. The amplifier device (68) includes a low pass filter (58) coupled to the audio signal source for developing a filtered signal from the audio signal. A frequency dividing circuit (74) is coupled to the signal by a predetermined factor. The amplifier device further includes a decoding circuit (76) coupled to the low pass filter for selecting between a left and a right audio channel of the filtered signal and developing a decoded signal and a muting circuit (78) is coupled to the decoding circuit. The muting circuit (78) only passes the decoded signal at levels above a variable threshold level. A power amplifier (80) is coupled to the frequency dividing circuit (74) and the muting circuit (78) for amplifying the audio signal.

摘要： An improved electromagnetically actuated valve (10) is disclosed. The improved valve design includes a layer of structurally stable, non-magnetic material (52), preferably Kapton or Chrome, disposed intermediate the core element (16) and the electromagnetic element (32, 34) of the valve, and a core element and electromagnetic element fabricated from a high electrical resistive iron material. The layer of non-magnetic structurally stable material and high resistance core element serve to eliminate the hysteresis effect in the magnetic force of the valve. The core element may also include radially extending (50) or axially extending (48) perforations through the core element. The axial and radial perforations serve to reduce the weight of the core design and the axial perforations serve to reduce the effect of the air spring created in the gap as the core element approaches the electromagnetic element during operation of the valve.
