Abstract: A fiber optic connector assembly has an MT connector. The MT connector has a housing. A first slot is formed in a front surface of the housing. The first slot extends across a width of the front surface of the housing and partially down a length of the housing. A pair of slots is formed in a rear surface of the housing. The pair of slots extends across a width of the rear surface of the housing and partially down the length of the housing. An aperture is formed through a side surface of the housing and between the pair of slots. The aperture extends completely through the housing. An opening is formed in a central area of the rear surface of the housing and in communication with the aperture. A channel is formed between the first slot and the aperture connecting the first slot to the aperture. At least one securing pin is formed within the first slot.

Abstract: Systems, apparatuses, and methods are provided for actuating one or more load management devices on a wind turbine and/or a wind turbine blade. Each actuator may exhibit one or more beneficial qualities including appropriate actuation speed/force characteristics, size and/or weight characteristics, and/or increased reliability and consistent operation in a variety of operating conditions. According to some aspects, the actuator may be a direct pneumatic actuator, a ramp slide pneumatic actuator, a scissor actuator, a linear induction actuator, a belt actuator, a closed cam follower actuator, a screw drive actuator, a solenoid actuator, a rack and pinion actuator, a cylindrical cam follower actuator, a Y-belt actuator, an offset rotary drive actuator, a tape style actuator, a rigid tape actuator, a deformable membrane actuator, a memory alloy actuator, and/or a crank slide actuator.

Abstract: A mounting arrangement for a load compensating device is provided. The mounting arrangement includes a cover sheet connected to a housing via a plurality of protrusions. The cover sheet may form a portion of a surface of an airfoil rotor blade. The housing may include a plurality of clamps extending outward from the housing and configured to contact an inner surface of the airfoil rotor blade. By tightening the clamps onto the interior surface, the device is mounted to the blade and the cover sheet may deform to correspond to the airfoil geometry of the airfoil rotor blade. The mounting arrangement may further include a mounting plate configured to permit the housing to float within the aperture formed in the airfoil rotor blade, and a tab arranged on one end of the mounting plate to distribute centrifugal force to the surface of the airfoil rotor blade.

Abstract: An apparatus and system for automatically deploying an air deflector of a load compensating device when there is a loss of communication or power is provided. In some examples, the apparatus and system may include a spring configured to rotate a gear, thereby deploying the air deflector. In some arrangements, the spring may be a torsion spring and may be biased to rotate the gear when released from a hold position maintained by a latch. The latch may be controlled by a release mechanism, such as a solenoid, that may be configured to activate upon occurrence of a communication loss event. The release mechanism may release the latch, thereby releasing the spring and deploying the air deflector.

Abstract: A taut, torsional flexure is used in a compact drive for scanning light and is of beneficial use in a lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, the module being operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color.

Abstract: A dispensation device having a nozzle defining a chamber and a dispensation orifice which communicates with the chamber. A transfer pin is moveably received within the chamber and moveable between a retracted position and a dispensing position. In the dispensing position, a portion of the contact end extends out of the chamber through the dispensation orifice. A driven element contacts the transfer pin, with the drive element magnetically coupled to a driven element. A drive element is oriented to magnetically move the driven element and thus magnetically position the transfer pin.

Abstract: A method of centering a disk pack on a base rotatably supporting the disk pack includes performing a series a steps while the disk pack is rotating. A reference timing signal is generated. A first imbalance in the rotating disk pack is detected, and a first imbalance signal is produced. The first imbalance signal is correlated with the reference timing signal to produce a first correlation value, which indicates a location of the first imbalance relative to the reference timing signal. Based upon the first correlation value, a first impact is applied to the base, causing the base to shift relative to the disk pack. As a result of the first impact, the first imbalance moves to a second imbalance. The second imbalance is detected, and a second imbalance signal is produced. The second imbalance signal is correlated with the reference timing signal to produce a second correlation value, which indicates a location of the second imbalance relative to the reference timing signal.

Abstract: A head disk assembly includes a base, a cover attached to the base and a spindle motor mounted to the base. The spindle motor includes a shaft, an inner cylindrical portion surrounding the shaft, and an outer cylindrical portion surrounding the inner cylindrical portion. The outer cylindrical portion has an annular surface and the inner cylindrical portion has a cylindrical surface which extends above the annular surface. The head disk assembly also includes a disk mounted on the spindle motor such that the disk surrounds the outer cylindrical portion; the disk includes a recording surface which is substantially co-planar with the annular surface. The head disk assembly also includes a disk clamp for clamping the disk to the spindle motor and a washer positioned between the disk clamp and the recording surface for transferring radial loads to the inner cylindrical portion of the spindle motor.

Abstract: A head disk assembly ("HDA") comprises an enclosure including a base and a pivot bearing cartridge having a shaft and a outer shell rotatable about the shaft. The outer shell has a cylindrical surface. The shaft is affixed to the base at a predetermined location. The enclosure has an internal volume with a limited height above the predetermined location. The cartridge has an elongated portion in the volume, the elongated portion having a height approximately equal to the limited height. The HDA further comprises a plurality of rotating disks, each having at least one recording surface. The HDA further comprises an arm stack comprising a plurality of arms, and a plurality of head gimbal assemblies. Each arm has a stacking portion and a cantilever portion. Each head gimbal assembly has one end attached to the cantilever portion of a respective arm and has an opposite end positioned adjacent a recording surface.
