Abstract: The present disclosure features systems and devices for robotic debridement and perforating of finger- and toenails, as well as methods of use of the same. The systems and devices may be used for in the treatment of fungal infection of the nail, as well as for cosmetic uses, e.g., pedicure and manicure.

Abstract: A robot assembly includes a drive system attached to a frame. The robot drive system includes a base platform, a driver motor base assembly attached to the platform and an adjustment device that adjustably attaches the base platform to the drive motor assembly. The robot frame includes a top horizontal beam assembly that defines a first rectangle, a bottom horizontal beam assembly that defines a second rectangle and a set of main support beams that join the first rectangle to the second rectangle to define a shape of an isosceles trapezoid.

Abstract: The present invention is a robotics construction kit that serves as a platform for children to engage in problem-solving and innovative thinking in science, technology, engineering, and mathematics. By designing and building robotics constructions from an apparently simple set of blocks that encapsulate the kinetic, electronic, and software elements of robots, children and others can encounter, explore, and experiment with basic principles of science and computation. Unlike existing robotics construction kits for education, the present invention embodies computation in every element, which affords understanding systems of distributed computation, rather than systems of top-down control.

Abstract: A construction kit comprises a plurality of building modules, wherein at least one of the building modules is functional and adapted to perform a specific behavior. In some embodiments, each of the building modules includes at least one connection face adapted to pass either data or power from a first face of a first building module to a first face of a second building module. In certain other embodiments, each connection face of the building modules is electrically connected with each of the other faces. The kit includes at least one connector adapted to couple the at least one functional module to at least one other module while providing up to three degrees of freedom between the functional module and the at least one other module.

Abstract: A carrierless storage system enclosure includes an ejection mechanism to permit installation and removal of data storage devices (e.g., hard disk drives) without tools, carriers, and manual cabling.

Abstract: A filesystem-aware storage system locates and analyzes host filesystem data structures in order to determine storage usage of the host filesystem. To this end, the storage system might locate an operating system partition, parse the operating system partion to locate its data structures, and parse the operating system data structures to locate the host filesystem data structures. The storage system manages data storage based on the storage usage of the host file system. The storage system can use the storage usage information to identify storage areas that are no longer being used by the host filesystem and reclaim those areas for additional data storage capacity. Also, the storage system can identify the types of data stored by the host filesystem and manage data storage based on the data types, such as selecting a storage layout and/or an encoding scheme for the data based on the data type.

Abstract: A system for cutting windows or openings in mats used in framing works of art. The system involves the use of a variably positionable head to which a cutting blade is attached for cutting a beveled edge in the mat. A longitudinal drive means, transverse drive means, and orthogonal drive form a combined positioning device capable of moving the head in any direction. A rotational drive means may also form part of the combined positioning device for rotating and adjusting the position of the blade. A linear variable displacement transducer is coupled to the head and operatively coupled to the orthogonal drive to maintain the head a constant distance away from the mat so the blade cuts a continuously smooth beveled edge in the mat.

Abstract: A medium to high viscosity liquid flow detector and alarm sub-system for use with apparatus for automatic liquid dispensing machines for mastics, sealants, adhesives, and the like, comprising a liquid pressure sensing device disposed in the liquid flow path of the liquid dispensing gun of the machine. The liquid pressure sensing device derives an output electrical signal indicative of the instantaneous liquid pressure in the liquid flow path. A differentiating circuit differentiates the liquid pressure indicating signal to derive a rate of change in fluid pressure signal. The rate-of-change signal is supplied to an indicator for signalling the existence of an undesired rate-of-change in liquid pressure condition and is indicative of a bubble or void in the liquid mastic, sealant, or the like being dispensed.

Abstract: A low cost cam controlled mechanical positioning apparatus for automatically tracing out a predetermined path of movement for the working head of a machine tool or the like is described. The apparatus comprises a set of two large diameter disc type control-drive cams secured in parallel planes on a common drive shaft rotatably supported on a base member and driven by an electric motor through suitable gearing. Respective cam followers engage cam surfaces formed on the undersides of the large diameter control-drive disc cams and are connected to respective linkages for translating movement of the cam follower to a working head to thereby move the working head in a predetermined path of movement in an x-y plane. A working head supporting boom is secured to a transport mechanism which is movably supported on wheel and track elements and mounted for movement along respective x and y axes by the respective linkages driven by the cam followers.
