Abstract: Motion planning with implicit occupancy for autonomous systems includes obtaining a set of trajectories through a geographic region for an autonomous system, and generating, for each trajectory in the set of trajectories, a set of points of interest in the geographic region to obtains sets of points of interest. Motion planning further includes quantizing the sets of points of interest to obtain a set of query points in the geographic region and querying the implicit decoder model with the set of query points to obtain point attributes for the set of query points. Motion planning further includes processing, for each trajectory of a least a subset of trajectories, the point attributes corresponding to the set of points of interest to obtain a trajectory cost for the trajectory. From the set of trajectories, a selected trajectory is selected according to trajectory cost.

Abstract: A system includes two or more lifting devices attached to a structure each lifting device having a drum rotated by a motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. In certain embodiments, each of the lifting devices are quickly and easily detachable from the structure by way of a flange and mounting bracket. The flange and mounting bracket have holes which are coaxially aligned. A pin or other fastener is used to join the flange and mounting bracket together. Two or more lifting devices may be connected to and moved along a mounting bracket.

Abstract: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. A cable is incorporated into the line to transport at least one of power and data along the line to an object or device at the end of the line. In certain embodiments, the cable is configured to support all or a portion of the load. In other embodiments, the line includes a load-bearing wire separate from the cable which is configured to support all or a portion of the load.

Abstract: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. Logistics electronics are mounted proximate a first end of the drum and power electronics are mounted proximate a second end of the drum. In general, the logistics electronics include lower power electronics that enable data processing as well as data and commands to be communicated to the apparatus from an external location. By contrast, the power electronics may include higher power electronics needed to receive power and drive the motor.

Abstract: A reactor device (100) for reaction fluid comprising a reaction vessel (102) comprising: an end cap (104) comprising at least one passage (112) for the reaction fluid; and at least one tube (116) which extends through the reaction vessel (102). The reaction vessel is operable to receive a control fluid outside the at least one tube (116) for controlling the temperature inside the at least one tube (116). A manifold (200) is connectable to the end cap (104) and comprises at least one channel (206) for reaction fluid. An outlet (208) from the manifold (200) is in fluid communication with the tube (116). The end cap (104) has a thermal conductivity of greater than 1 watt per square meter kelvin to provide a thermal coupling between the control fluid and the manifold (200).

Abstract: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. The transmission includes at least one stage of gearing to reduce a gear ratio of the motor relative to the drum. A shaft couples the motor to the transmission and a locking mechanism selectively locks the shaft to prevent rotation of the drum. In certain embodiments, a braking mechanism may be provided in addition to the locking mechanism to slow the motor when the motor is not applying torque to the drum. This may slow the motor sufficiently to enable engagement of the locking mechanism.

Abstract: An apparatus includes a drum to draw in or let out a line and a motor coupled to the drum to apply a torque thereto. The drum includes a groove formed in an outer surface thereof to accommodate the line. A roller is provided that tracks the groove and extends into the groove. The roller pushes the line into the groove. In certain embodiments, the roller pushes the line to a bottom of the groove to ensure that the line is properly seated therein.

Abstract: An apparatus includes a drum to draw in or let out a line, and a motor and transmission coupled to the drum to apply a torque thereto. In certain embodiments, the motor and transmission are substantially entirely contained within the drum. In the same or other embodiments, a bearing may provide support for both the transmission and the drum.

Abstract: An internal bone fixation system for the treatment of bone anomalies, such as thoraco-lumbar spinal instability. In accordance with a preferred embodiment, the fixation system includes a plate anatomically contoured to match the profile of lateral aspects common to thoracic and lumbar vertebrae, as well as the anterior profile. The contour of the plate allows for quicker implantation time, a lower profile, and a fit which allows for biomechanical load-sharing which increases the mechanical properties of the construct (i.e., stiffness, strength, and fatigue life). Moreover, the fixation system includes a fastener screw-plate interface which forces proper alignment between fastener screws and the plate, provides “pull-out” resistance and evenly distributes stresses on both the screw and the plate. Ledges are located on the medial surface at either end of the plate. The fixation system also includes set screws which effectively turn the screw construct into a bolt construct.
