Abstract: A physical measuring tool comprising one or more members for determining the correct length of stock of various shapes of a given thickness and width range required to form various enclosed shapes with predetermined internal dimensions. One embodiment is an easy to use enclosed shape measuring tool that allows jewelers to fabricate rings of various widths from stock with great precision and fit without costly revision, as the measurements it makes are calibrated to the proportional relation among the thickness, length, width of material, and finished fit of ring. Each measuring element includes a raised fence for bracing material against to maximize measurement accuracy, and other convenient elements such as a thickness-measuring member. Such a tool replaces mathematical calculations and charts for determining the ratio among length and thickness of stock, and width and interior dimensions of enclosed shapes representing a significant time and resource saver for fabricators.

Abstract: Embodiments of the present invention include a calibration and measurement system designed primarily for use in the rapid evaluation and characterization of open or visible wounds in patients. The invention in a preferred embodiment comprises a set of colored concentric rings, typically constructed of paper or synthetic paper. The practitioner removes only as many rings, from the center outward, until the entire wound is visible within the open aperture at the center of the remaining rings. The area dimensions of the wound are then read out from the size of the inner remaining ring. Photography optionally records the wound appearance and size. A related system is developed for linear dimensioning of wounds. This embodiment is also designed to standardize the color scheme for accurate photography wound description. The color scheme is also applicable to a linear device to accurately describe wound size. Embodiments of the invention are also useful in forensic and accident investigations.

Abstract: Methods of sizing a nasal airway by using certain measurements of digits may include (a) pressing a distal portion of a digit of a hand against a resilient, flat surface, such that flesh of the distal portion of the digit spreads laterally on the surface; (b) measuring the digit's width at a digit measuring level, the measuring level being the widest part of the digit distal to a distal-most interphalangeal joint of the digit; and (c) identifying a nasal airway size as that size which correlates most closely to the digit's width as measured at the digit measuring level.

Abstract: A method of manufacturing a sizing ring adapted to accurately fit an individual for a recloseable ring. The method includes: providing a generally arcuate member and having first and second ends; forming a segment of reduced cross sectional area along the generally arcuate member to form a living hinge therein and to define first and second shank portions; and configuring the first and second ends to form a connector such that the sizing ring is a one piece polymer member configured for movement between an open position, in which the sizing ring is adapted to be positioned over a portion of an appendage without sliding over a length of the appendage, and a closed position, in which the sizing ring is adapted to form a band around the appendage and has an inner surface that is generally circular to correspond to an associated ring size.

Abstract: A digital ring sizing device includes a cylinder removably positioned directly about the selected user finger, and a mechanism for determining a ring size of the selected user finger. The ring size determining mechanism is housed within an interior of the cylinder and connected directly thereto. A mechanism visually displays the determined ring size of the selected user finger, and is directly connected to an outer surface of the cylinder and further is electrically coupled to the ring size determining mechanism. The ring size of the user is automatically displayed in numeric characters by the visual displaying mechanism after the ring size determining mechanism calculates the ring size of the selected user finger.

Abstract: A ring insert kit includes a plurality of ring inserts and optional a selection template. The ring inserts are arranged in predetermined sizes for selection using the template. The ring inserts are insertable into one or more finger receiving openings within a pair of scissors for reducing the opening size to accommodate the size of the user's fingers.

Abstract: A method for making beaded jewelry is provided. The method utilizes a megaphone shaped device having a small diameter first end and a larger diameter second end. The circumference of the first end is that of one part of the human body, such as a child's wrist. The circumference of the second end is the size of another part of the human body, such as an adult ankle. Markings on the girth of the device sequentially graduate in circumference and define graduated bracelet, anklet and other jewelry sizes. When one is making a bracelet or other article of jewelry of strung beads, the diameter of the beads affects the finished length of the article. Use of the device takes into account the diameters of the beads and thereby ensures that the finished item of beaded jewelry will fit the intended wearer.

Abstract: A tooth circumference measuring device is disclosed that device provides a strap that is placed around a dental patient's tooth and retracted into an at least generally conformal relationship (i.e., snuggly fit around the tooth) using a strap adjusting mechanism. The strap is operatively interconnected to a gage such that when the strap is secured about the tooth with a predetermined amount of tension, the gage indicates the circumference of that tooth. In one embodiment, the strap adjusting mechanism includes a reel that is interconnected to the strap. Upon rotation of the reel, a first portion of the strap is wound or unwound about a perimeter of the reel such that a second portion of the strap disposed about a tooth may be tensioned or loosened. In a further embodiment, the strap adjusting mechanism is operative to provide a consistent tension between measurements.

Abstract: A finger ring shim is comprised of a member for being wedged between a loose ring and a finger. A groove on the member is arranged for cradling the ring. The groove has a width which is selected to receive a ring of a particular thickness. The member has a shim thickness which is selected to match a gap size between the ring and the finger. A tool for determining the proper groove width and shim thickness is comprised of an elongated and tapered sheet with a scale along an edge, and slots of graduated widths. The sheet is inserted between a finger and a ring until it is snug. The point on the scale under the ring is correlated with a suitable shim thickness, and the smallest slot which the ring can fit into shows the suitable groove width.

An attaching device is secured to each ring of each set of gauges for enabling the ring to be removably and slideably secured to the holding device. A ring guard-type item is secured to each ring of at least one set of gauges.

Abstract: A combined measuring device for indicating both the ring size of a user and the size of a gemstone, includes an elongate housing having a hollow interior and a first measurement scale located along a length of the housing. The first measurement scale includes indicia representative of different ring sizes. An indicator is slidably mounted on the housing for movement along the measurement scale, with at least a portion of the indicator extending into the hollow interior of the housing. A flexible measuring band has a first end removably connected to an end portion of the housing and a second end connected to the indicator portion within the housing. The flexible measuring band forms a measuring loop outside of the housing such that movement of the indicator along the housing changes the size of the measuring loop to thereby adjust to the size of an object to be measured. A second measurement scale is located on a length of the flexible measuring band and includes indicia representative of distance.
