Abstract: An example adapter assembly may comprise an adapter cage to removably mount to a riser board of a computer system. Further, the example adapter assembly may comprise an adapter board disposed on the adapter cage, wherein the adapter cage is to receive multiple computer components, and the adapter board is to engage with the multiple computer components.

Abstract: In one aspect, a system for torsional damping of electric traction drives comprises dual Kalman filters to correct for oscillations based on measured traction motor speed and commanded traction motor torque. A first Kalman filter can perform a state space estimate of the shaft torque providing negative feedback to the final torque command in order to eliminate resonant components from the commanded torque and quickly damp external disturbances. A second Kalman filter provides a state space estimation of the load torque or, equivalently, load acceleration. This second Kalman filter can ignore commanded torque and can provide a damping feedback when the wheel speed deviates from the vehicle speed.

Abstract: An inventive system and method for managing vehicle power is presented. The novel technology provides a means to automatically shutdown a vehicle's engine when conditions are such that engine power is not needed, reducing fuel consumption as well as lowering noise and emissions. A series of conditions are examined to determine whether engine power is needed and hence whether shutdown can be safely performed. The inventive system and method can also determine when power is again needed by the engine and can re-start the engine automatically at such times.

Abstract: Some embodiments of the present invention provide a sensor which partially or fully disables operation of a vehicle access and entry device when a barrier of the device is moved sufficiently. In some embodiments, the vehicle access and entry device is an inboard barrier of a wheelchair lift, includes a tie rod coupled to the inboard barrier and to a housing, and triggers a sensor when the tie rod is moved sufficiently with respect to the housing.

Abstract: In some embodiments, a wheelchair retention device for a wheelchair lift is provided at a height no greater than about the center of gravity of a wheelchair on the lift. In some embodiments, the retention device is a seatbelt-like device mounted to lift handrails and elevated above the platform surface. Also, in some embodiments, a damped retention device is provided. The damped retention device can include an extendable non-locking belt that slows a wheelchair or other object contacting the retention device by using friction forces. In some embodiments, the wheelchair can contact the damped retention device prior to contacting the outboard rollstop, and is slowed substantially, thereby preventing the wheelchair from tipping or flipping over upon contacting the rollstop and retaining the wheelchair on the lift.

Abstract: A secure safety anchor that is easy to utilize is provided for attachment to structural angle irons in marine installations and the like. The anchor includes a vise grips with movable and stationary jaws, and a head welded to the stationary jaw. A flange surface portion of the head extends substantially perpendicular to an imaginary line between the vise grips jaws when in the clamping position, and a number of force concentrating set screws pass through the flange surface at an angle of about 15 degrees with respect to the imaginary line. A through-extending opening in the head provides for attachment of a safety belt clasp.

Abstract: A cable dead end, and method of dead end formation, that can be readily utilized in the field with a minimum of equipment and components, yet providing a durable, tight, dead end. The cable end is cut off and a ferrule is slipped over the cable end onto the cable. The strands at the end of the cable are unwound and separated, an insert is disposed over the core strand and is disposed within a general bird-cage configuration of the cable strands at the cable end. The ferrule is then moved over the bird-cage configuration and to the end of the cable, and the void space inside the ferrule between the strands, ferrule, and insert is packed with steel wool. Then an anerobic, structural, single component adhesive (e.g. an oxygenated methacrylic) is poured into the ferrule interior volume, and quickly cures. Preferably the insert is barbed, and the interior cross-section of the ferrule is elliptical.

Abstract: Apparatus which renders a self-elevating drilling platform self-mobile on land and a method of moving the drilling platform employing the apparatus. The self-elevating platform includes a body, forward and rear legs, and means for adjusting the legs by moving the legs with respect to the body and moving the body with respect to the legs. The apparatus includes a launch pad which will be pivotally mounted to the platform beneath the body. In operation, the legs of platform are adjusted so that, alternatively, the launch pad swings forward beneath the body when the pad is elevated off the ground and the body pivots forward around the pad when the pad is on the ground.
