Abstract: A security wallet insert for thwarting loss of credit cards includes a carrying case which is installed in a foldable wallet, the insert having pockets for holding individual credit cards, and a movable member which must be extended relative to the insert to allow a card to be removed from a pocket, the extended movable member uncovering a “replace credit card” message and making it difficult to close the wallet and thereby impractical to return it to a pocket or purse. A spring activated by removal of a card from a pocket prevents the extended movable member from being returned to a closed non-obstructing position unless the spring is depressed, thus providing a positive reminder that a credit card must be returned to the wallet after the user has made a transaction, and thereby minimizing the probability that the card will be inadvertently left at a place of use.

Abstract: An auxiliary control apparatus mechanically couples forces exerted on a manually operable auxiliary hand control knob to an input member of a micro-manipulator of the type used to move a point of an object such as an ultrasonic bonding tool tip relative to a workpiece in scaled ratios of motions at an end of the micro-manipulator input member. The apparatus includes a 4-bar parallelogram linkage which is mounted to a structural support member of a micro-manipulator, and which includes a rear laterally disposed lateral linkage bar pivotably connected to inner and outer parallel longitudinally disposed linkage bars which are pivotably coupled at front ends thereof to a front laterally disposed linkage bar.

Abstract: A carrying case for sporting equipment, particularly hockey sticks and accessories such as pucks includes a block-shaped body which has an upwardly protruding carrying handle, a first longitudinally disposed, vertical side of the body which has formed therein a pair of longitudinally disposed, vertically spaced apart troughs, and a first side lid hingedly fastened to a lower edge of the body, the side lid having formed in an inner surface thereof a pair of troughs shaped similarly to those in the body. Stacked pairs of hockey stick handles are placed in either the lid troughs or body troughs, with the lid pivoted outwardly from the body to an open position; with the lid pivoted to a closed position in contact with the body, the lid and body troughs confront one another to form a pair of closed, longitudinally disposed channels which retain the handles therewithin. The lid is held in a closed position in contact with the body by releasably engageable fastener elements located on the lid and body.

Abstract: A golf putter including a head which has detachably fastened to the body thereof a face plate provided with a plurality of striking surfaces which are selectably and interchangeably oriented by a player to a forward facing use position, the striking surfaces each having different ball-impacting characteristics, e.g., rebound factor, hardness, and/or frictional characteristics. In one embodiment, the face plate has flat front and rear parallel surfaces in which are fitted inserts with different ball-impacting characteristics, the face plate being attachable conformally to the front face of a putter head body with a selected insert in a forward-facing use position by a pair of screws inserted through holes in the face plate in opposite sides of the inserts and tightened into a pair of aligned threaded bores which extend perpendicular into the front face of the putter head body.

Abstract: A dental prostheses modeling system includes a molding tray for molding the base of a quadrant or full-arch dental model cast which has a longitudinally disposed partition panel disposed generally between upper and lower surfaces of the tray that forms therewithin an upper well for receiving liquid die stone to mold the base of a dental impression model, and a lower well shaped symmetrically to the upper well for providing clearance for optional manipulating pins installable in the bases of selected die segments modeling individual dental prostheses severed from the hardened die stone base of the model. The partition panel includes peripheral flanges for supporting the base of the dental model, and an openable central portion for enabling a hardened dental model to be ejected from the tray, and for providing access for manipulating pins depending downwardly from die segments.

Abstract: A method for improving resolution of X-ray radiography systems of the type used to obtain images of internal features of human bodies or to view contents of luggage articles, cargo containers and the like comprises positioning a plurality of baffle plates between the rear surface of an X-ray radiation detector array and a back stop used to limit transmitted X-ray radiation to a safe level. The baffle plates are made of a high atomic-number metal such as iron or lead which reduces by absorption, scattering or other attenuating processes the intensity of X-ray radiation back scattered from the back-stop onto the detector array, thus reducing noise contributions to signals output from detector elements of the array and thereby improving the quality of radiographic images formed from detector output signals.

Abstract: A dental prostheses modeling system includes a tray having in an upper part thereof a trough for receiving a semi-liquid modeling material or casting material such as plaster of Paris or die stone, the trough having opposed vertical walls in which are formed alternating vertically disposed ribs and grooves for forming complementary shapes in sides of a casting molded in said tray, a base portion of which has in outer walls thereof alternating vertically disposed grooves and ribs, the trough having a frangible base plate which overlies an upwardly concave cavity for receiving liquid die stone after the upper casting has solidified, hardened and been removed, the base plate being broken and removed to uncover an elongated aperture joining the upper trough to the lower cavity enabling the cast to be ejected from the tray, pins fitted into selected portions of the casting base, the casting reinserted into the trough, and the tray inverted to receive liquid die stone which hardens to form a stone base matrix for i

Abstract: 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.

Abstract: A method and apparatus for processing signals output from an array of X-ray radiation detectors which receive X-ray radiation emanating from an object irradiated by a source beam of X-ray radiation, to thereby produce an visual image of internal object features, utilizes repetitive sampling P times and digital accumulation of signals output from each detector to increase signal-to-noise ratio of the images by the factor 1/?P. In a basic embodiment, each of the N detectors in a linear detector array is sampled P times. In another embodiment, artifacts resulting from decay of detector pre-amplifier output voltages on capacitors of low-pass filter circuits, referred to as pseudo-integrators, are reduced by sequentially sampling and accumulating each of N detector amplifier output voltages P times in turn, and repeating the sampling and accumulating sequence Q times, thereby reducing variations in the P×Q accumulated values between the first and last detector channels of an N detector array.
