  • Publication number: 20240361543
    Abstract: A system including a device configured to be partially inside of a target object (and to remain affixed to such object substantially irremovably and in an unchanged orientation with respect to such object at least on a time-scale comparable to term of life or use of the target object itself) to provide chronic access to an internal object location from an outside location and communication with such location along multiple communication channels that are spatially separate and substantially immovable with respect to one another while remaining moveable together and synchronously with the object. Delivery of electromagnetic energy and a material stimulus along the first and second communication channels is carried out such as to necessarily maintain unchanged mutual spatial positioning and orientation between the channels regardless of whether the channels are being used or not and regardless of whether the target object—together with these channels—is spatially repositioned.

  • Patent number: 9748052
    Abstract: A system and method for an automatic transfer switch comprising a fixed contact, a first oscillating rod communicatively and operatively connected to a first movable contact, a second oscillating rod communicatively and operatively connected to a second movable contact, a link rod communicatively and operable connected to the first and second oscillating rods, and a guide plate. The automatic transfer switch is operable to position the guide plate based at least on a state of a solenoid. A permanent magnetic actuator communicatively and operatively connected to the link rod via a third oscillating rod is operable to rotate the first oscillating rod or the second oscillating rod based at least on the position of the guide plate.

  • Patent number: 8579315
    Abstract: A modular wheelchair assembly is adapted to be reconfigured between a fixed angle of tilt, a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's knees and a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's center of gravity. The reconfiguration is achieved by modifying a limited number of selectively removable components of the support assembly or the pivot assembly of the wheelchair.

  • Patent number: 7752233
    Abstract: Described are techniques for clustering a data set of objects. Divide phase processing is performed to partition the data set into two or more partitions forming a hierarchy of the objects. Merge phase processing may be performing using the hierarchy to determine one or more disjoint clusters of objects of the data set. Optional preprocessing may be performed to determine weights for one or more features of an object.
