Abstract: A personal ability vehicle (PMV) includes a frame with front and rear subframes. A steering mechanism is mounted on the front subframe and includes a steering front wheel connected to a tiller. The rear subframe includes a suspension mount comprising a pair of rear support legs. An anti-tip suspension includes a pair of trailing arms each mounting a trailing wheel. Each trailing arm is pivotally mounted on a respective support leg whereby the suspension is inevitable through a limited range of motion about a transverse suspension pivotal axis. A pair of spring assemblies are attached to the trailing arms and are adapted for selectively engaging the support legs to provide a counter-rotational torque force around the suspension pivotal axis in order to resist backwards tipping of the PMV, for example, when it is ascending an inclined sloping surface. Relatively uniform proportional, weight distribution on said steering front, main and trailing wheels is maintained throughout a range of loads.

Abstract: A soil cultivating apparatus including a tractor towing a row cultivator by means of a three-point linkage. The row cultivator includes a fixed portion and a moveable portion having soil scarifying tools. The movable portion is laterally moveable relative to the fixed portion by means of linkages and is effected by a hydraulic actuator under control of tool bar control systems which is able to determine the position of the moveable portion relative to the fixed portion by means of a sensor. Mounted upon the moveable potion is a DGPS antenna GPS receiver that forms part of the control system. The control system has a microprocessor which operatively executes a stored program. The microprocessor receives data from an intra-rig sensor and from the GPS receiver specifying the absolute coordinate of the movable portion relative to the earth.

Abstract: A method and system for reducing Global Navigation Satellite System (GNSS) carrier tracking loop ambiguities comprising: receiving a plurality of GNSS satellite signals with a first antenna in operable communication with a first tracking device and a second antenna in communication with a second tracking device in at least one GNSS receiver; and sharing of data between the first tracking device and the second tracking device. The sharing is configured to facilitate a commonality in a carrier phase derived in the first and second tracking devices. The sharing also results in a cancellation of the commonality when a difference phase is formed between a carrier phase from the first tracking device and a carrier phase from the second tracking device.

Abstract: A system for removing osteal cement and prosthetic joint components in connection with a prosthetic joint revision includes a controller connected to and controlling operation of a transducer, such as a surgical saw or drill. A tool mounted on the transducer is adapted for engaging the prosthetic joint cement mantel and melting an engagement portion of same. The cement in the engagement portion is resolidified with the tool tip embedded therein. The tool thus bonds to the cement mantel, and is used for vibrating, softening and breaking up same when operation of the transducer resumes. An osteal cement and prosthetic device removal method includes the steps of melting an engagement portion of the osteal cement mantel, bonding a transducer-mounted tool to the cement mantel by resolidifying the cement engagement portion and reactivating the transducer for vibrating, softening and breaking up the cement mantel whereby it can be removed from the patient.

Abstract: A storm drain inlet for a below-grade collection box including front, rear and side walls and a top. The inlet includes a pair of side columns, which connect to the collection box side walls. An upper crosspiece extends between the side columns and is attached to the collection box top. A lower crosspiece comprising a back plate extends between the side walls and provides a form for the rear edge of a concrete apron poured in front of the collection box. The side columns, upper crosspiece and concrete apron define an inlet throat open to the collection box interior. A roadway or parking lot structure can include curbs, which can be poured adjacent to the collection box into proximity with the inlet side columns. The curbs are preferably not rigidly connected to the inlet in order to accommodate relative movement therebetween. The inlet can be adapted for both poured-in-place and precast collection boxes. It can be scaled to accommodate various widths and heights.
