A free weight assistance and training device includes a base and a generally upright weight support structure mounted on and extending upwards from and over the base. A free weight support bar is connected to a computer-controlled weight tensioning device which is mounted on the base generally adjacent the upright weight support structure, the connection between the free weight support bar and the computer-controlled weight tensioning device consisting of at least two cables movably mounted on the upright weight support structure. The computer-controlled weight tensioning device, the at least two cables and the free weight support bar operatively cooperate with each other such that tensioning force applied by the computer-controlled weight tensioning device via the at least two cables to the free weight support bar controllably decreases the amount of downwards force exerted by the free weight support bar and weights thereon.

A method and apparatus for unloading long ribbon rails which are carried on a transport car on bunks which hold the rails in four or five different tiers each containing eight to ten rails. A special railcar is equipped with a gantry crane which feeds the rails from the bunks into power driven thread boxes. The thread boxes grip the rails and feed them rearwardly onto the railway bed. After the first two rails have been unloaded side by side, the next pair are fed into the thread boxes. The thread boxes feed these rails out of the bunks as the train is moved forwardly at the same speed as the rails are fed rearwardly so that the rails are unloaded end to end with the first pair of rails. The railcar has retractable over the road wheels that allow it to be towed on the roadway to the site of the rail transport car.

The invention relates to an apparatus (100) for accommodating at least one person (25) and for partially limiting the freedom of movement of the person (25) accommodated in the apparatus (100); comprising a platform (7a) and a first annular part (13) arranged above the platform (7a) for surrounding the at least one person (25), wherein the annular part (13) is rotatable in relation to the platform (7a), wherein the annular part (13) can be moved up and down in relation to the platform (7a).

A catheter kit including a drainage catheter hub having a rotatable lever handle adapted to secure a suture thread to maintain the anchor configuration of the distal end of the catheter to secure the position of the catheter within the patient's body. The rotatable lever handle has a released position for allowing movement of the suture and a secured position for preventing movement of the suture. A rotatable lever handle adapted to secure the proximal portion of the suture that may otherwise remain loose during the procedure. The rotatable lever handle and associated rotatable barrel can be depressed relative to hub body in a locked configuration to prevent inadvertent rotational movement of the rotatable lever handle and a release slot or release button that can be actuated by the practitioner with a release tool to allow for rotational movement of the rotatable lever handle.

An applicator device comprising a casing and an application element wherein the application element is displaceable with respect to the casing against a return force.

An apparatus for providing multiple vaccinations of poultry simultaneously is described. A neck injection, breast injection, two wing injections, and an eye mist or drop may be performed in one operation. The apparatus holds the bird in position for precise location of injections, thereby reducing wasted vaccine. The risk of injury to the bird during the process is minimized by greatly reducing the manual handling of the bird during vaccination. Vaccination costs are also reduced by the reduction of labor otherwise required in this process.

A hurdle has a crossbar and a pair of vertical legs. The hurdle is designed to give way or collapse when the crossbar is struck by a user to minimize the risk of injury and thereby decrease the user's fear of injury. This is done either by splitting the crossbar into separate left and right sections, or by splitting each of the legs into separate top and bottom sections. This permits the separate sections to break apart from an aligned, end-to-end orientation which they possess in an operative position of the hurdle into a nonaligned orientation after the hurdle has given way or collapsed. An elastic member connects the separate sections and urges the sections back into their aligned, end-to-end orientation when a user picks the sections of the hurdle up and resets the hurdle.

A surgical treatment can involve creating a pattern of perforations in a tissue structure to allow lengthening of that tissue structure. For example, a pattern of perforations can be created in the transverse carpal ligament of a patient suffering from carpal tunnel syndrome (CTS) that allows the carpal ligament to lengthen slightly. This lengthening can relieve pressure on the median nerve, thereby reducing the symptoms of CTS while maintaining the structural integrity of the wrist. A surgical instrument for use in perforating a tissue structure (such as the transverse ligament) can be an elongate structure with one or more retractable blades. Such a tool can be used in either an open or minimally invasive procedure to create a desired pattern of perforations in the tissue structure.

A fastening tool having plural power source ports that, when contemporaneously activated, deliver compressed air to a fastener driving assembly to drive a fastener into a workpiece.

The adaptive system and method for ultrasound sensing comprises re-evaluating over time the detection threshold for predetermined sensing positions along the scanning direction to cope for the static target and environment changes at the sensing positions. The method includes comparing the measured echo value at each sensing position to a reference echo value corresponding to the same sensing position, and to iteratively determine a new reference value whenever the echo value is greater than the reference echo value and that the difference between the measured echo value and the reference echo value is lower than a detection assurance factor. The use of the adaptive ultrasound sensing system and method allows locating the sensor at different location without requiring a new calibration thereof, since the sensor learns the clutter dynamically and the detection thresholds are being built accordingly without being dependent on the environment in which the sensor is located.
