    • A drive mechanism (16A, 16B) having a bi-stable motor (18) driving an actuator (22) with a high starting torque, and a slower, regulated velocity as the actuator moves through its range of travel. This advantageously maintains high torque margins at low velocity, and lowers the kinetic energy of the bi-stable actuator at end of travel by limiting the terminal velocity (Wm) and establishing a softer stop. A solenoid may be used in one embodiment. Actual bi-stable motor values are obtained immediately before the move to maintain accurate control of the motor, such as the resistance and inductance of the motor coil. For instance, the bi-stable motor (46) may be driven into a stop (50, 52), and the coil resistance(Rm) may be calculated by sensing current (Im) associated with the calibration voltage (Vd). Inductance (Lm) may be measured similarly by applying low level AC currents. Back-emf is sensed through the coil resistance, and an estimated motor rotation rate is sent to a feedback loop (68) to maintain the desired rate.
    • 具有双稳电动机(18)的驱动机构(16A,16B)以高起动转矩驱动致动器(22),并且随着致动器在其行程范围内移动而变慢。 这有利于在低速度下维持高扭矩余量,并且通过限制终端速度(Wm)并建立更软的停止来降低行程结束时双稳态致动器的动能。 在一个实施例中可以使用螺线管。 在移动之前立即获得实际的双稳态电机值,以保持电机的精确控制,如电机线圈的电阻和电感。 例如,双稳电动机(46)可以被驱动到停止(50,52)中,并且可以通过感测与校准电压(Vd)相关联的电流(Im)来计算线圈电阻(Rm)。 可以通过施加低电平AC电流来类似地测量电感(Lm)。 通过线圈电阻感测反电动势,并且将估计的电动机转速发送到反馈回路(68)以保持期望的速率。

    • A device for translating rotary to linear motion and vice versa includes a reciprocating linearly moving shuttle (34) with a central aperture (41). The aperture (41) has a pair of opposing gear racks (46, 48) protruding towards the center and which capture therebetween a pair of pinion sectors (52, 54) rotatably mounted to the crankpin (42) of a rotatable crankshaft (44) with the axis of crankshaft rotation perpendicular to the linear path of the shuttle (34). The pinion sectors (52, 54) are free to rotate about the crankpin (42) and articulate independently of each other through a selected angular range. When the crankpin (42), including the pinion sectors (52, 54), is inserted into the aperture (41) of the shuttle (34) with the pinion sectors (52, 54) engaging the racks (46, 48), motion is transferable between the crankpin (42) and the shuttle (34) through the pinion sectors (52, 54).

    • A motion converter (10) employs a shuttle (34) movable in a reciprocating fashion along a rectilinear path and having an aperture (42) therein. One side of the aperture (42) is defined by a first trackable profile (58) and an opposite side of the aperture (42) is defined by a second trackable profile (60). A pair of conjugate drivers (54, 56) is rotatably mounted on a crank pin (44) positioned within the aperture (42) of the shuttle (34). The conjugate drivers (54, 56) have tracking profiles (62, 64) which are in continuous conjugating engagement with the trackable profiles (58, 60) of the shuttle (34). Each of the tracking profiles (62, 64) has the same circumferential length as its corresponding trackable profile (58, 60).

    • A device (10) for interconverting rectilinear and rotary motion is designed so as to reduce side thrust exerted on a frame (18, 22) by a slide (12) as the slide reciprocates linearly relative to the frame and such rectilinear motion is converted into the rotary motion of a crank (24, 26) or vice versa. More particularly, an elongated opening (46), which receives a crankpin (28) of the crank such that the crankpin moves back and forth along the elongated opening, is provided in a swing (40) mounted for oscillatory movement relative to the slide. At least one arm (48, 50) is pivotally attached to the frame and to the swing so as to effect the oscillatory motion of the swing relative to the slide as the slide reciprocates relative to the frame. As the slide reciprocates relative to the frame, the orientation of the elongated opening relative to the slide is constantly varied.
    • 用于相互转换直线和旋转运动的装置(10)被设计成当滑块相对于框架线性地往复运动时,通过滑块(12)减小施加在框架(18,22)上的侧向推力,并且将这种直线运动转换成 曲柄(24,26)的旋转运动,反之亦然。 更具体地,接收曲柄的曲柄销(28)的细长开口(46)设置成使得曲柄销沿着细长的开口来回移动,摆动件(40)安装成相对于滑块进行摆动运动。 至少一个臂(48,50)可枢转地附接到框架和摆动,以便当滑块相对于框架往复运动时,相对于滑块来实现摆动的摆动运动。 当滑块相对于框架往复运动时,细长开口相对于滑块的取向始终是变化的。
