Devices, systems, and methods for positioning an end effector or remote center of a manipulator arm by floating a first set of joints within a null-perpendicular joint velocity sub-space and providing a desired state or movement of a proximal portion of a manipulator arm concurrent with end effector positioning by driving a second set of joints within a null-space orthogonal to the null-perpendicular space. Methods include floating a first set of joints within a null-perpendicular space to allow manual positioning of one or both of a remote center or end effector position within a work space and driving a second set of joints according to an auxiliary movement calculated within a null-space according to a desired state or movement of the manipulator arm during the floating of the joints. Various configurations for devices and systems utilizing such methods are provided herein.

The power-operated mud flap device may include a mud flap adapted to be positioned adjacent to an outer face of the existing vehicle tire. The device may also include a mechanism for automatically displacing the mud flap between a raised and a lowered position defined along a vertical plane. The automatic displacing mechanism may further include a drive shaft coupled to a power actuated motor. First and second linear adjustable driven shafts may be mated to the drive shaft. The driven shafts are preferably registered perpendicular to the drive shaft. Additionally, each driven shaft may include a threaded male member and a female member containing an axial bore. The male member may be rotatably inserted into and extracted from the female member in such a way that the longitudinal length of the driven shaft decreases and increases respectively, thus displacing the mud flap into a raised or lowered position respectively.

A high speed, high displacement steering device used for rapid mirror or light source pointing consisting of a pivoting central element and mounting stem, two orthogonally arranged and offset “V” shaped flexure elements connected to two orthogonally arranged moving elements which are driven by electromotive actuators. Said moving elements are connected to a base structure via parallel motion flexures which serve to prevent undesirable bending forces in the linear actuators, while at the same time preventing undesirable translation movements, cross coupling of motion and resonances. A third type of orthogonal rod flexure restrains the remaining axis of translation motion, namely a translation of the central pivoting element in a direction perpendicular to the tilting axes. Piezoelectric, electrostrictive or similar actuators operate either separately or simultaneously to drive the central element in the only two remaining unrestrained tilting axes, via the offset “V” shaped flexures, producing tilt in any commanded direction. A sealing cover containing an elastic diaphragm to accommodate tilt may be added to the outer support structure as required for protection in harsh environments.

In an industrial multilayer fabric, narrower wefts of a small diameter are placed between lower side wefts so as to sandwich a knuckle formed by a lower side warp on the lower surface side of the fabric.

The industrial fabric is obtained by stacking at least upper side wefts and lower side wefts one after another and weaving these wefts with warps, wherein narrower wefts having a smaller diameter than that of the lower side wefts and forming a shorter crimp than that formed by the lower side wefts on the lower side surface are arranged between the lower side wefts; and at a knuckle portion formed by warps passing under one or two successive lower side wefts, the narrower wefts form a crimp passing under lower side warps so as to sandwich, from both sides, one knuckle or two knuckles formed by two adjacent warps under two adjacent wefts.

‘Flip and Change’ allows users to confidently change clothing without worrying about staining their clothes. The invention has two pieces of silk or polyester material that can be attached to a neck strap held together by hook-and-loop-fasteners. Other materials and fastening means may be used. Once the user has secured the neck strap, he/she may tuck the shorter piece of material into his or her collar or behind the front of the shirt (on the inside), while the longer piece may be flipped up to cover the face. When the (main) garment (such as a shirt or blouse) is removed, the invention prevents makeup from transferring to the clothing. The longer piece of material may include a decorative knot at the end.

Device for driving a compressor of a gaseous fluid having a rotor and a stator disposed extending along a common longitudinal axis. The stator comprises connection leads implemented as segments of conductor wires of coils. The device has a plug housing for receiving a connecting element which is electrically connected with a connection lead of a conductor wire with a plug connector. Support element is disposed on the stator with a receiving member for the plug housing. Receiving member comprises a connecting passage and plug housing is slid into the receiving member in such manner and disposed in the receiving member such that in each instance one connecting passage of the receiving member and the connecting element for receiving a plug connector correspond. Plug housing is filled at least in regions with potting compound and connected with support element under hermetic seal. Methods for assembling the device are provided.

A reinforced gas valve assembly having a valve stem secured to a main valve body adjacent a valve member. The valve includes a retaining cover plate configured to secure the valve stem to the valve body and a reinforcement member coupled to both the valve stem and the retaining cover plate for restricting radial movement of the valve stem.

The invention relates to a control unit (1, 12), comprising a control element (4, 15), particularly for a closing drive of a motor vehicle lock. Said control unit comprises a housing (2, 13), a drive unit, and a spindle gear unit having a spindle nut and a spindle (3, 14). Said spindle gear unit can be driven by the drive unit and the control element (4, 15) can be moved by means of the spindle (3, 14), the control element (4, 15) having a means for guiding the control element (4, 15) in the housing (2, 13) so that the control element (4, 15) can be prevented from rotating about an axis of movement.

The hair brush generally comprises a handle and a removably coupled brush head retainer. The brush head retainer is adapted to receive a variety of different hair brush heads comprising a variety of types of bristles. The handle comprises a centrally tapered configuration that is easily grasped by a user. Upper and lower portions define a central longitudinal passage. Axially aligned within this passage is a handle coupling assembly comprising an activation member, push rod, spring, barrel, and one or more ball bearings. The brush head retainer comprises a brush head retainer lower opening, an inner annular groove, and one or more lower pins. The inner annular groove comprises an angled lower portion which is transversely aligned with the barrel side openings. The push rod is moveable between first and second positions such that the brush head retainer may be coupled and decoupled.
