Abstract: The invention is a method for restoring the use of a single-use RFA catheter system wherein the catheter is restored to first-use clean and sterilized status, and operating restrictions have been circumvented without affecting the first-use operational specifications.

Abstract: A structure authentication system includes a sensor configured to sense identifying features of a three-dimensional (3D) printed structure and generate identifying feature data based on the identifying features, as well as a processor configured to receive, from the sensor, the identifying feature of the 3D printed structure. The processor is also configured to analyze the identifying feature data along with a non-fungible token (NFT) database that correlates a plurality of NFTs to a plurality of identifying feature data to determine whether the 3D printed structure is associated with an NFT within the NFT database. Additionally, the processor is configured to query a blockchain to determine whether the NFT is authentically associated with the 3D printed structure. The processor is also configured to, in response to determining that the NFT is authentically associated with the 3D printed structure, send a notification to a user device indicating that the 3D printed structure is authentic.

Abstract: Shoulder strengthening systems can provide multidirectional and dynamic resistance to shoulder movement of a user. A shoulder strengthening system can include a frame, a joint pivotably coupled to the frame, a resistance mechanism coupled to the joint, and a shaft coupled to the joint. Resistance mechanisms can include a first hydraulic member and a second hydraulic member. The first hydraulic member can be configured to restrict relative motion of the joint about a first axis and the second hydraulic member can be configured to restrict relative motion of the joint about a second axis. The shaft and the joint of a shoulder strengthening system can be configured to move together relative to the frame about the first and second axes.

Abstract: A footrest apparatus for a wheelchair and the like has a pair of supporting frame configurations supporting a pair of foot plates to be position in a first position for use and a second position for transportation and/or storage. Each of the supporting frame configurations has a connecting shaft rotatably received in a vertical tube of a front wheel assembly. The vertical tube is affixed to a frame structure of the wheelchair and the like. The connecting shaft and the vertical tube in combination bear and transfer a foot load of the user and therefore a locking device provided between the connecting shaft and the vertical tube for locking the connecting frame configuration in a selected one of the first and second positions, will not bear the foot load, resulting a configuration convenience for conducting an unlock action.

Abstract: An intravenous support apparatus comprises a pole, means attachable to the pole for hanging an intravenous liquid supply on the pole, and a base including a plurality of disconnectable legs having respective inner ends joined one with another, the joined inner ends forming a central body of the base to define a central passage extending vertically through the base, the central passage receiving a bottom end of the pole for supporting the pole in a upright position, each leg including a first material containing a core element of a second material which is heavier than the first material.

Abstract: A handle grip for ambulatory aid appliances has a soft top portion and a rigid body portion. The handle grips may be attached to a wheeled ambulatory aid appliance such as a rolling walker, wheelchair, stroller and the like in a selected position to provide a comfortable and secure hand grip to a user of the ambulatory aid.

Abstract: A bath tub rail assembly for use on a bath tub sidewall includes a hand grip and a clamping device. The hand grip and the clamping device are adjustably connected such that the hand grip may be adjusted in both height and angular orientation relative to the bath tube sidewall when the bath tub rail assembly is attached thereto.

Abstract: A walker device for assisting an individual with mobility which is temporarily convertible to a wheeled transportation chair, includes a frame structure having two front legs and two rear legs, each of the legs having a leg extension adjustably attached thereto and supported on a rotatable wheel. A seat is attached to the frame structure. A backrest is selectively disposed in a front position for a rearward seating condition or in a rear position for a forward seating condition. A footrest assembly is optionally attached to the frame structure and is adapted to pivot about first and second pivoting axes parallel to each other, between a folded position and an unfolded position optionally with different height levels.

Abstract: The present invention provides a telescope system having enhanced capabilities for configuring and calibrating a telescope, operation and control of the telescope, and viewing of imagines from the telescope. The present invention employs a control system for controlling the position and orientation of the telescope. In one embodiment, the system uses GPS systems and the like to determine the position of the telescope. The system may use either the light detected by the telescope or measurements of stars within the field of view to determine the orientation of the telescope. Following calibration, the user may operate a control system to reorient the telescope to the desired field of view. Further, the user may operate software that allows the user to select stars, constellations, or other objects of interest. Based on this selection, the system operates the telescope to alter its field of view to view the selected object.

Abstract: A bath tub rail assembly for use on a bath tub sidewall includes a hand grip and a clamping device. The hand grip and the clamping device are adjustably connected such that the hand grip may be adjusted in both height and angular orientation relative to the bath tube sidewall when the bat tub rail assembly is attached thereto.

Abstract: A foldable bath seat includes at least a seat member and two leg assemblies each having two legs connected with a crossbar. Each of the crossbars is pivotally mounted to a bottom seat portion to allow the legs to pivot between a folded position and a downwardly extended position.

Abstract: A comfort cane includes a cane shaft having an upper end and lower end thereof, and a two-piece handle affixed to the upper end of the cane shaft. The handle includes a rigid body portion substantially defining a profile of the handle in a top view of the handle, and a top portion attached to the body portion. The top portion is soft and resilient with respect to the body portion.

Abstract: A walker device for assisting an individual with mobility which is temporarily convertible to a wheeled transportation chair, includes a frame structure having two front legs and two rear legs supported or rotatable wheels. A seat is attached to the frame structure. A backrest is selectively disposed in a front position for a rearward seating condition or in a rear position for a forward seating condition. A footrest assembly is optionally attached to the frame structure and is adapted to pivot about first and second pivoting axes parallel to each other, between a folded position and an unfolded position.

Abstract: A safety mat for use in bathtubs or shower stalls provides comfortable and safe conditions for users during a bath or shower. The safety mat can be optionally used with a seating aid placed directly on a floor of a bathtub or shower stall, and restrains substantial movement of the seating aid in order to prevent a user sitting on the seating aid from falling therefrom.
