Abstract: A temperature sensor approximates fluid temperature averaged across a location range by including an outer armour layer. Several resistance temperature detectors are spaced in an electrical circuit which is then protected in the outer armour layer. The outer armour layer is woven without any seam to enhance its longitudinal thermal conductivity. In the preferred weave, twenty-four stands of sixteen metal threads each are helically woven. The electrical circuit is sealed interior to the armour layer so any condensation or moisture within the armour layer does not affect the circuit. The armour layer is sealed on its ends to the sheathing of the underlying circuit, so the armour layer provides stress relief across the connections of the resistance temperature detectors to the circuit. The resulting sensor is robust and durable, as well as very flexible.

Abstract: The invention concerns a method for encoding at least a source image using a hierarchical mesh defining at least two nested spaces corresponding each to a decomposition level of said meshing, which consists, at least at a decomposition level n (except the first decomposition level), in delivering only image coefficients expressed in a base of functions defined in a space orthogonal to the space corresponding to the preceding decomposition level n?1, said functions being selected so that said image coefficients enable to optimize for said decomposition level n the data already transmitted for the preceding decomposition level n?1, so as to produce a reconstructed image, representing said source image, with optimized restoration quality for said decomposition level n.

Abstract: A technique for end-grain creation is employed for obtaining rapid and uniform drying of lumber while simultaneously reducing warp. The stability-kerfing responsible for the improved drying of the lumber decreases the edgewise bending strength by less than ten percent, a loss readily recovered due to the ability of stability-kerfing to achieve lower and more uniform moisture contents than those realized in the contemporary drying of lumber. The improved moisture condition provided by the stability-kerfing also fosters future dimensional stability at the time of entry into the marketing stream compared to that for contemporary lumber. The required stability-kerfing is easily accomplished by the specialized implementation of existing saw equipment and associated technology into the contemporary processing lines.

Abstract: Any issues associated with manufacture of a part are identified and highlighted on a part model. A software method and system then uses motion of the part model for communicating the manufacturability issues to the customer. The motion can include a repositioning of a part rendering to a preferred orientation position, a fly-around so the customer can appreciate the next zoom location, and then a zooming in on the issue desired to be shown. Alternatively or in conjunction with the zooming and fly-around motion, the orientation of the part rendering showing the manufacturability issues can be three-dimensionally manipulated such as with a click-drag-drop command of the customer's computer mouse. By adding a moveable aspect to the communication, customers can much better understand which changes are recommended or required of the part.

Abstract: A 27?×28?×½? calendar/organizer that combines a large, 12-page, printed paper calendar with a ¼?-½? thick and “pin-receiving” backboard. The front sheets are printed with a calendar array of days and weeks, with each day having a height of at least four inches, such as days which are 4½ inches tall by 4 inches wide. The front sheets are attached to the backing board at their upper ends by two heavy duty staples, and have three mounting holes punched in aligned locations between the staples. The backing board is provided by double layer cardboard with each layer thicker than the plurality of front sheets, so the backing board can receive and hold a tack or push pin without regard to whether the tack or push pin extends through none, one or all of the front sheets. The backing board may extend longer than the front sheet calendar pages, so as to facilitate an additional “pinning surface” for items not associated with any particular day of the month.

Abstract: A hitch includes a hitch engagement, a hitch tongue and a connecting bridge portion which are forged or otherwise formed as a single, integral, monolithic metal structure. The hitch engagement includes a recess exposed on its bottom side which significantly reduces the weight and material cost of the hitch. The hitch includes generally uniform wall thicknesses with the exception of stress pyramids of greater thickness disposed on the side walls of the bridge portion. A front wall to the hitch engagement is provided which slopes relative to the longitudinal axis of the hitch and connects the side walls bounding the recess. An anti-vibration device can be used within the recess to prevent the hitch from rattling in the hitch receiver.

Abstract: The invention concerns the refinement of a triangular mesh representing a three-dimensional object (3D), said mesh consisting of an arrangement of vertices and triangular surfaces, each defined by three references to the vertices which it links, and having three edges each linking two of said vertices. The invention is characterized in that said method comprises a step which consists in selecting at least a region of interest, said mesh refinement being carried out locally on at least one region of interest.

Abstract: A first customer provides a CAD file defining the surface profile for a part to be molded to the system, and a second customer does the same for a second part. The system determines whether the materials match and the run dates overlap, thereby qualifying the parts for use in a multi-customer mold block. The system assesses the part surface profile (which could have any of a virtually infinite number of shapes) of the parts submitted and lays out the parts from multiple customers on one or more multi-customer mold blocks. Savings are generated, such as by reducing redundancies in press clean-up, in set-up, in tooling, and in surface finishing. Due to these savings, the system provides a quotation of the part to at least one of the customers which differs from the quotation that would be provided if each part was run independent of parts of other customers.

Abstract: An improved fifth wheel hitch for attaching a trailer to a towing vehicle. The hitch includes an outer box support frame having two rails for mounting the trailer hitch to the towing vehicle, a spherical bearing mounted in the frame having a ball joint, and a latch assembly affixed to the spherical bearing to allow the assembly to have two degrees of movement, and a head body. The latch assembly comprises a base plate, a jaw fixed at a first elevation, and a vertically displaceable jaw. A means are provided to raise the vertically displaceable jaw above the level of the fixed jaw to allow release of the king pin latch. When the jaws are coplanar they capture the kingpin of a trailer, and safely lock the trailer to the hitch.

Abstract: Automated, custom mold manufacture for a part begins by creating and storing a collection of information of standard tool geometries and surface profiles machinable by each of the standard tool geometries. A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities, surface finish and material, which an independent of the shape of the part.

Abstract: A method for reusing profile insert blades maintains axial, radial and profile dimensions of a cutting tool. The method includes duplicating an original profile on a used profile insert blade by sharpening a profile edge of the used profile insert blade to form a sharpened profile edge with a new profile that is shifted longitudinally along a length of the profile cutter blade relative to an original profile position. Material is removed from a reference edge of the sharpened profile insert blade to form a new reference edge, for positioning the resharpened blade in a longitudinally changed position so that the new adjusted profile has similar axial, radial and profile dimensions as compared to the original profile.

Abstract: An intramedullary nail structure is formed with opposing dynamization windows, and spacers of a bioresorbable material are positioned within the dynamization windows. The dynamization windows are longer than they are wide. The spacers may be integrally formed as a single insert. The nail is used with a bone fastener such as a bone screw which is advanced transversely through the bone and into the spacer, preferably in a bicortical attachment with the bone. The bone fastener is smaller across than the dynamization windows, so each spacer spaces the bone fastener relative to its dynamization window. As the spacers resorb, stress (at least in one direction) is increasingly transmitted through the fracture site rather than through the intramedullary nail. The positioning of the bone fastener, the shape and size of the dynamization windows and spacers, and the material of the spacers all allow design control over the type and amount of dynamization seen at the fracture site.

Abstract: A bone support structure is formed with opposing dynamization windows, and spacers of a bioresorbable material are positioned within the dynamization windows. The dynamization windows are longer than they are wide. The spacers may be integrally formed as a single insert. The bone support assembly is used with a bone fastener such as a bone screw which is advanced transversely through both the insert and the bone. The bone fastener is smaller across than the dynamization windows, so each spacer spaces the bone fastener relative to its dynamization window. As the spacers resorb, stress (at least in one direction) is increasingly transmitted through the fracture site rather than through the bone support structure. The positioning of the bone fastener, the shape and size of the dynamization windows and spacers, and the material of the spacers all allow design control over the type and amount of dynamization seen at the fracture site.

Abstract: An external fixator includes a main body and an outrigger for extending over a fractured joint, such as a wrist joint. The main body can be positioned next to a right arm, or flipped over and positioned next to a left arm. The outrigger is attachable to extend either to the left or to the right of the main body, as appropriate. A distal body is removeably connectable to the distal end of the main body, and the distal body can be affixed to bone on the opposite side of the fracture to immobilize the joint where the fracture occurs. The distal body is connected to the main body with an adjustable securement section which provides six degrees of adjustment freedom. The outrigger is attached to the main body through a slide plate in a dual rail configuration which provides two dimensions of adjustment. Fragment pin supports ride in a track of the outrigger, and provide seven degrees of adjustment freedom for directed fixation of fragments at the fracture site.

Abstract: A ball hitch has a hitch tube which fits within a hitch receiver of a towing vehicle. The trailing end of the hitch tube is perpendicular cut. A hitch tongue has a contact face adjoined to the hitch tube and an exposed face opposite the contact face. A hitch tube receiving recess is defined in the contact face, with the hitch tube receiving recess receiving the perpendicular cut trailing end of the hitch tube therein. The exposed face of the hitch tongue is preferably disposed at an angle relative to the abutment surface of the hitch tube receiving recess which contacts the cut at the trailing end of the hitch tube.

With any such modifications, the system provides the customer with a quotation of the cost to manufacture the mold or a number of parts. The quotation is based upon mold manufacturing time as automatically assessed from the part drawings.
