Abstract: Embodiments of the invention provide a high-reliability, cost-effective electro-hydraulic servo-valve assembly that is not susceptible to failure caused by contaminated fluid. In particular embodiments, the electro-hydraulic servo-valve assembly includes a rotary valve that may be actuated by either a direct-coupled Limited Angle Torque (LAT) motor, a geared, brushless DC motor, or some other rotary electric actuating element with an integrated driver circuit. In particular embodiments, the rotary valve element made up of an outer sleeve element and an inner spool element, with matching ports and slots, respectively.

Abstract: A trip block is provided. The trip block includes a single housing which commonly houses multiple valve assemblies. Each valve assembly includes a rotary valve member arrangement. The rotary valve member arrangement includes a spool and a sleeve with a predefined radial clearance between the spool and sleeve.

Abstract: Microphone stand attachment systems to attach a support base to a longitudinal axial element easily, quickly and securely. An attachment guide may include a threaded plug and a support base may include a threaded socket. In embodiments, a male tapered flange may frictionally lock with a female tapered element of a socket to secure a longitudinal axial element to a support base. Specific attachment structures, in embodiments, are also described, as are various plugs, tapers, sockets and methods of attaching a support base to a longitudinal axial element.

Abstract: The present invention may provide a support assistive device for a user having a frame assembly (1), a vertical pelvis support element (2) connected to the frame assembly which may primarily support the ischial tuberosities (34), and a horizontal pelvis support element (3) which may primarily support the anterior superior iliac spines (35) of a pelvis (1a). It may provide such support with minimal or no hand or arm support. By supporting on the anterior superior iliac spine (35) on either side, a moment can be created to assist in turning even without the use of hands by simply turning the direction of the pelvis (1a). The created moment of the present invention is more natural to the user in turning the pelvis and as a result the device. The present invention may also provide a fluidic braking assembly (53) for any rotatable elements (48), which can be advantaged to assist a user in supplying an increase of force to actuate the braking action.

Abstract: A high strength, engineered collapsible support has separate shear bearing surfaces and pivot elements which permit efficient manufacture and higher strength. Unitary brace attachment is achieved with designs which can be molded and yet both efficiently manufactured and made acceptably strong such that heavy items such as performance or commercial speakers can be mounted stably. An extendible sleeve permits adjustment; a semiautomatic as well as manual clutch assembly permits quick securement of the top mast to the tripod; compression rings allow a secure fitting to be established between various pieces; leg upper end caps allow the legs of the tripod to be coupled to the main mast of the tripod; an end plug can serve to reduce the number of parts necessary to couple the various leg braces to the bottom of the main mast. Strength is achieved through multiple shear surfaces located at a distance from a pivot retention element and with parallel braces.

Abstract: A support assistive device for a user having a frame assembly, a vertical pelvis support element connected to the frame assembly which may primarily support the user in the ischial tuberosity region, and a horizontal pelvis support element which may primarily support the anterior superior iliac spine region of a pelvis. It may provide such support with minimal or no hand or arm support. By supporting on the anterior superior iliac spine on either side, a moment can be created to assist in turning even without the use of hands by simply turning the direction of the pelvis. The created moment of the present invention is more natural to the user in turning the pelvis and as a result the device. Additionally, a fluidic braking assembly for any rotatable elements is provided, which can be advantaged to assist a user in supplying an increase of force to actuate the braking action.

Abstract: A device and method of supporting a bicycle load in a workstand, wherein the workstand can be supported on only two members which establish three individual points of support. The workstand can utilize at least one rotatable leg to collapse the workstand into a portable and manageable configuration that facilitates transporting and storage. The load support member to which the bicycle is either directly or indirectly coupled can be coupled to the support base off-center from the geometric center of the support base to provide a more stable configuration for the stand as well as to establish the member out of the way of the bicycle which must be supported. In addition, a space saving footprint established by the support base allows the workstand to be positioned against walls and in corners.
