摘要： A personal mobility vehicle (PMV) lift for loading and offloading a personal mobility vehicle (PMV) into and from a rear portion of a vehicle, the vehicle having an interior floor and a trailer hitch rigidly attached to the rear of the vehicle to which the PMV lift is rigidly engageable. The PMV lift receives substantially all of its support from the trailer hitch and includes an elongated laterally extending lifting boom and a drive mechanism connected adjacent a proximal end thereof. The drive mechanism includes an elongated flexible lifting cable or belt which is operably connectable for raising and lowering the PMV by operation of the drive mechanism. An upright stanchion is supportively connected to the lifting boom while an elongated lift support arm is supportively connected to a lower end of the stanchion. A trailer hitch engaging member is connectable at one end to the trailer hitch, the other end of which is connected to a proximal end of the lift support arm. The PMV lift is substantially fully supported by the trailer hitch.

摘要： A personal mobility vehicle lift for a vehicle having a door opening and a floor. The personal mobility vehicle lift includes a platform for supporting a personal mobility vehicle (PMV) thereatop. An upright preferably telescoping lift mechanism raises and lowers the platform in an up and down motion. An elongated stationary frame member is structured for connection atop and oriented preferably parallel to the floor of the vehicle. An elongated moveable frame member is connected to the stationary frame member preferably for reciprocal lengthwise movement. The moveable frame member is connected to the lift mechanism for reciprocal lengthwise movement. A drive mechanism operably interconnects the stationary and moveable members and the lift member whereby, when the platform is in the upper position, the platform is moveable from its outside position through the door opening into the vehicle.

摘要： A universal power wheelchair lift and restraint system for attachment to a rear of a vehicle. The system includes a lift platform having a substantially flat, uninterrupted generally rectangular support surface sized in length and width to be similar to, and to supportively receive, a broad size and configuration range of power wheelchairs thereon. A power lift mechanism is attachable to the rear of the vehicle and supportively connected to the platform for elevating and lowering the platform with the power wheelchair positioned thereatop. A locking tiedown mechanism is pivotally connected in proximity to each corner of the platform and in proximity to each of the corner areas of the power wheelchair atop the platform. Each tiedown includes an elongated flexible strap extendable from a rolled configuration and having an attaching member securely disposed at a distal end thereof. An attachment connected to each side of the power wheelchair is configured to be securely connectable with the attaching member of each of the tiedowns on each corresponding side of the power wheelchair whereby, when said straps are evenly tensioned and automatically locked, the power wheelchair is immobilized atop said platform.

摘要： A flow conduit may have at least one orifice is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier. The flow pathway between the orifice and the source is temporarily blocked with a degradable material or barrier. The material disintegrates (e.g. under the influence of time or temperature) to optionally produce a product that removes the temporary coating in the area adjacent the barrier. The method is useful in one non-limiting context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the temporary coating is a filter cake.

摘要： Systems and methods for maritime infrasound detection can include at least one waterborne platform. A microbarometer, inertial measurement unit (IMU) and heave cancellation component (HCC) can be mounted on the waterborne platform. The HCC can receive a pressure input from the microbarometer and the IMU to generate an output pressure that can be indicative of an infrasound signal of interest (SOI). The HCC can further include a filter and an adaptive algorithm. The filter can receive IMU pressure and environment noise pressure as inputs. An error signal from the HCC output can also be supplied through a closed feedback loop that includes a Recursive Least Squares adaptive algorithm, which can further include a weighted, tapped delay line. The system can further include a remote data center for receiving the HCC output from the waterborne platform(s), which can be buoys, vessel or USV's.
