摘要： A method and apparatus for measuring pressures exerted on human feet or horses' hooves comprises a rectangular array of piezoresistive force sensors encapsulated in a thin polymer package that is inserted into a shoe, or incorporated into a sock that may be pulled over a foot or hoof. The preferred embodiment employs novel piezoresistive normal force or pressure sensing elements which include a polymer fabric mesh impregnated with conductive particles suspended in an elastomeric vehicle, preferably silicone rubber. The piezoresistive mesh layer is sandwiched between an array of row and column conductor strip laminations, preferably made of a nylon mesh impregnated with printed metallic paths. In a variation of the basic embodiment, each normal force sensor element is bordered by laterally and longitudinally disposed pairs of shear force sensor elements, each of the latter comprising a pair of adjacent resilient piezoresistive pads that have longitudinally contacting lateral surfaces. The pads are slidably movable, and when urged into more or less intimate contact in response to shear forces directed normal to their tangent contact plane, the electrical resistance between the pads varies in a predetermined way as a function of the shear forces.

摘要： A method and article for optically encoding copies of a printed document to make the copies unreadable to a casual observer uses a mask having alternating transparent and opaque, white-colored areas placed over the document prior to making a first photocopy of the document, referred to as a first coded half. The opaque regions of the mask, which preferably are spatially periodic, obscure portions of printed letters to make the first coded half unreadable. The mask is then shifted in location relative to the document so as to position transparent regions of the mask over formerly obscured areas, and vice versa. A second photocopy, or second coded half is then made. The first and second coded halves are then physically transmitted or telefaxed to a recipient, who must superimpose the first and second coded halves to render the document readable.

摘要： A water inflatable structural module for constructing temporary dikes and related structures includes two identical elongated flattened cylinders sealed at opposite lateral ends to form a sealed, water-tight chamber within a cylinder. The cylinders are joined along a horizontal mid-plane to opposite longitudinal edges of a thin, flexible, elongated, rectangular web. A sealable inlet port in each of the two cylinders permits the cylinders to be inflated with water to form two relatively stiff, parallel, elongated cylinders attached at facing inner mid section lines to the flexible web. In a preferred version of the module the width of the web, and therefore the minimum spacing between the two cylinders with the web flat, is of the proper dimension to make the ratio of minimum spacing to inflated cylinder diameter lie in the approximate range of 1.75 to 1 to 2 to 1. That ratio allows tubes from a second and third module to lie side by side on the web of a first module, in tangential contact with the tubes of the first module. Thus constructed, any desired number of modules may be stacked to form an interlocking structure of any desired height, length and width without the use of any fastening elements, which resists lateral movement of modules with respect to one another, in a direction perpendicular to the longitudinal axes of the modules. The structural module is of elongated, substantially uniform transverse cross-sectional shape permitting fabrication of the module by a low cost extrusion process.

摘要： An improved thruster for propelling borescopes by the reaction forces generated by pressurized fluid expelled from the thruster has a desirably small cross-sectional profile made possible by its novel construction. The basic embodiment of the thruster comprises an elongated hollow cylinder sealed at one end by a bulkhead and supplied with pressurized fluid at the opposite, open end. A thin slot cut through the cylinder wall permits pressurized fluid to exit the hollow interior space of the cylinder, producing a reaction force useful in propelling a borescope tip to which the thruster is fastenable.

摘要： An apparatus for remotely orienting the distant tip of a flexible borescope cable to point in a desired direction utilizes a plurality of vertabrae-like annular disks disposed transversely within the hollow interior of the distal end of the flexible cable. Fine, flexible wires fabricated from a shape memory effect (SME) alloy are fixedly attached to outermost disk, and extend longitudinally backwards slidably through aligned holes in the other disks, and slidably through hollow flexible tubes rearward of the innermost of the disks. Electrical power supplied to flexible conductors at either end of each SME alloy wires from a controllable source of electrical current at the proximal end of the flexible borescope cable permits heating a selected SME alloy wire to a transition temperature which causes the wire to assume a memory length different from its length at ambient temperature, producing a tensional force on the end disk which results in a bending moment being imparted to the flexible cable enclosing the disk.

摘要： A normal force gradient/shear force sensor device and measurement method for measuring internal stresses in tissues of a person supported by a chair or bed includes a planar matrix array of peripheral normal force sensors radially spaced from central shear force sensors, comprising an electrically conductive disk located within a circular opening bordered by circumferentially spaced apart electrodes. The disk and electrodes are located between upper and lower cover sheets made of a stretchable material such as polyurethane; one cover sheet is adhered to the disk and the other sheet is adhered to a support sheet for the electrodes. Motion between the cover sheets in response to shear forces exerted on the array causes the disk to press more or less tightly against the electrodes varying electrical conductance between the disk and electrodes proportionally to the magnitude and direction of the shear force. Each normal force sensor includes an electrically conductive film pressed between row and column conductors. Measurements of conductance values of pairs of sensor, which vary proportionally to normal forces exerted on the sensor, are used to calculate a gradient vector of normal forces exerted by a body part on the sensor array, which is combined with the shear force vectors in an algorithm to calculate internal reaction shear forces, e.g., on flesh near a bony prominence.

摘要： A transducer sensor array for measuring forces or pressures exerted on a surface includes a lattice of individual force or pressure sensor transducer elements comprising intersecting regions of pairs of elongated, flexible threads, each consisting of a central electrically conductive wire core covered by a layer of piezoresistive material having an electrical resistivity which varies inversely with pressure exerted on the material. The threads are arranged into two parallel planar sets, one set forming parallel spaced apart rows and the other set forming parallel spaced apart columns angled with respect to the rows. Row and column piezoresistive threads are retained in physical contact with one another at cross-over intersection points forming a lattice of piezoresistive junctions comprising individual force sensing elements, either by being bonded between a pair of thin, flexible, upper and lower laminating sheets, or by being interwoven to form a fabric mesh. In either case, the sensor array formed by the piezoresistive threads has a highly flexible, fabric-like characteristic which enables the array to readily conform to irregularly curved object surfaces. External normal forces or pressures exerted on an upper surface of the array placed on an object surface causes the electrical resistance of piezoresistive junctions which are compressed in response to the external forces to vary in a predetermined way, enabling a two-dimensional plot of electrical resistance values of each junction node to be made, thus enabling a two-dimensional matrix or map of pressure values exerted on each point of a surface, overlain by the sensor array to be generated. In one embodiment, the piezoresistive layer covering each piezoresistive thread consists of an electrically conductive elastomer, such as silicone rubber impregnated with carbon particles. In another embodiment, the piezoresistive threads consist of a wire core spirally wrapped with a plurality of thin polymer filaments that have a relatively poor electrical conductivity, such as nylon fibers which have carburized outer surfaces.

摘要： A method and apparatus for forming a three-dimensional image of a subsurface object utilizes an ultrasonic transducer wand to acquire ultrasonic images of an object, and a target plate attached to the wand which is optically imaged during each of a sequence of ultrasound scans, each of which is made with a different positioning of the ultrasonic scanning beam, thereby forming a sequence of quasi two-dimensional sonogram image slices of the object. Intersecting lines on the target are used to calculate a first coordinate transformation which transforms each optical image of the target plate and sensor to a normal view thereof, and each normally oriented target plate image is used to orient each sonogram image in a fixed coordinate system. A transformation matrix is then used to construct in a fixed coordinate system normalized two-dimensional sensor image slices of correct relative size, location, and orientation.

摘要： A remote wound assessment method and apparatus includes forming an oblique image of a wound and a target plate containing a rectangle and placed near the wound. Using a novel method of determining vanishing points where photographic images of parallel lines on the target object intersect, coordinate transformations are calculated which map the oblique image of the rectangle into a normal image thereof. Using the same coordinate transformations, an oblique image of a wound adjacent to the target plate is mapped into a normal view thereof, allowing precise measurement of wound features. By forming two separate images of a wound and target plate at two different oblique inclinations, three dimensional features of a wound may be measured.
