Rheumatoid arthritic patients and others are enabled to walk by means of an article of footwear which has an un-bendable platform provided on its upper surface with padding material and provided on its lower surface with a tread having heel and sole portions. The tread surface assumes a stable non-rocking condition when at rest on a flat ground surface. The heel portion has the entirety of its ground-contacting surface located forwardly of the anatomical rear edge of the patient's foot to reduce...

A metal band use facilitating assembly has a frame on which a metal band roll receiving receptacle is supported. Also supported on the frame is a band rewinder which permits a length of banding material cut from a roll disposed in the receptacle to be rewound and formed into a smaller, more manageable roll of the banding material.

A holder is provided which contains at least two different flossing materials. The one material is typically unwaxed dental floss. The other material varies in thickness and is selected so as to provide, when doubled over, the appropriate thickness to be presented between the interdental spaces to accomplish the proper cleansing of the interdental area. Various multi-stranded materials are provided for selection to be placed in the holder. Multi-stranded cotton embroidery thread may be used. The...

Apparatuses, methods, systems, and arrangements facilitate the upkeep of an electronic device. In certain described implementations, one or more analyses and/or determinations may be completed with regard to one or more replaceable issues. If the replaceable issue(s) are determined to be deficient (including potentially deficient), then the electronic device may produce one or more upkeep-related items to facilitate an operator's upkeep thereof. Exemplary replaceable issues may be related to con...

An apparatus for facilitating measurement of street grades from a top of curb (TC) planar datum line by a single person, including a pair of hook units, each having a rigid frame structure forming a top segment for resting on a top surface of a respective curb structure, a back segment for engaging a back surface of the curb structure, and a front segment extending from the top segment downwardly and away from the back segment for balancing the unit and for engaging various contoured front curb ...

A device for facilitating the attachment of decorative objects to an outer surface of a balloon comprises a plate-like base member, a first plate-like side wall member rigidly attached to the base member and oriented substantially perpendicularly thereto, and a second plate-like side wall member opposable to the first plate-like side wall member. Hinges pivotably secure the second plate-like side wall member to the base member so that the second plate-like side wall member can pivot from an open...

A dental tool for facilitating gingival retraction. A shank coupled to a handle terminates in a working end member having a curved edge shaped to generally conform to the curvature of the root surface of a tooth at the gingival level and also to the contour of the marginal gingiva. The exact shape of the curved edge varies with the type of tooth for which the tool is designed. The tool can also be used for shielding the gingiva from a cutting tool working close to the gingiva, and as an aid in i...

An electrochemical sensor wherein a FET for measuring chemical substances and a reference electrode are covered with a continuous hydrous polymer on an insulating substrate, and on the hydrous polymer, an enzyme-immobilized film is formed in a region positioned on a channel part of FET for measuring chemical substances.

Apparatus for introduction into the vessel of a patient comprising a guiding catheter adapted to be inserted into the vessel of the patient and a device adapted to be inserted into the guiding catheter. The device includes a flexible elongate member and a sleeve carried by the flexible elongate member near the distal extremity thereof and extending from a region near the distal extremity to a region spaced from the distal extremity of the flexible elongate element. The device also includes a gui...
