Abstract: An apparatus for assisting an individual in installing shoe coverings. The apparatus comprises a shoe covering casing and an outer casing in which the shoe covering casing is placed. A plurality of shoe coverings are placed within the shoe covering casing and are mounted so that an individual merely needs to place their foot down into the shoe covering casing and move their foot forward, causing a shoe covering to envelop the foot (preferably with a shoe on it). A mounting mechanism within the shoe covering casing continually sets the top shoe covering on the stack of shoe coverings into a position readily capable of accepting shoes so that the shoe coverings can easily envelop these shoes.

Abstract: A draft force sensor is provided for a coupling member coupled between a towing vehicle and a towed earth engaging implement, such as a scraper. The draft force sensor includes first and second bores extending through the coupling member. Each bore has a horizontal axis which extends perpendicular to a main fore-and-aft axis of the coupling member. The second bore is positioned above the first bore and spaced apart from the first bore. Each of the bores is surrounded by an outer cylindrical wall. Four electrical strain gauges are spaced apart and placed on the wall of each of the bores. A center line bisects an axis line which extends between the axes of the first and second bores. The axis of each bore is spaced apart from the center line by a distance which is less than a diameter of the bores. The strain gauges are connected electrically in a circuit which generates a draft force signal in response to draft forces applied to the coupling member.

Abstract: The invention provides an arrangement and method for detecting shorts between solder pads 31-34 in the production testing of circuit boards. The invention is particularly suitable for circuits driven by a constant current source or sink 6. By providing a conductor 101-103 between the solder pads, connected by a resistive path 11 to a source of potential 12, an additional current will flow through the resistive path to the solder pads if a short circuit exists in the region wherein the conductor is positioned. The additional current can be detected by applying a test probe in a circuit including the solder pads. The invention also provides an arrangement and method for detecting whether a polarity sensitive component 1 has been correctly connected to terminals 4, 5 on the circuit board. The component 1 can be a capacitor having one relatively wide positive terminal 2 and one relatively narrow negative terminal 3.

Abstract: A new approach to capturing and reproducing either live or recorded three-dimensional sound is described. Called MTB for “Motion-Tracked Binaural,” the method employs several microphones, a head tracker, and special signal-processing procedures to combine the signals picked up by the microphones. MTB achieves a high degree of realism by effectively placing the listener's ears in the space where the sounds are occurring, moving the virtual ears in synchrony with the listener's head motions. MTB also provides a universal format for recording spatial sound.

Abstract: A sealed, rotatable shaft assembly includes a housing that defines a bore that extends from an area exterior to the housing to an area interior to the housing. A shaft is rotatably disposed in the housing about an axis of the bore. The shaft extends through the bore between the interior area and the exterior area. An annular lip seal is disposed in the bore and is attached to one of the shaft and the housing. The lip seal extends from the one of the shaft and the housing to the other of the shaft and the housing in a contact seal so that rotation of the shaft with respect to the housing wears the lip seal to form a zero-clearance non-contacting seal. A labyrinth seal stage extends between the shaft and the housing. The labyrinth seal stage is disposed outward of the lip seal, with respect to the interior area and in communication with the lip seal.

Abstract: A method and process for the determination of presence and distribution of clouds is presented. The method involves the use of a sensor, such as laser ranger, for the collection of echo location measurement data from a three dimensional volume of the sky. The process involved in this invention utilizes the measurement data to evaluate and test for the presence of cloud banks. The process also utilizes the measurement data to quantitatively and qualitatively determine the cloud coverage amount and distribution. The preferred embodiment includes a laser ranger that samples the three dimensional volume at several azimuth-elevation angles through the application of a device capable of selecting azimuth-elevation angle values.

Abstract: A gas permeable ceramic investment mold is disposed in a casting chamber and filled with melt to be solidified via a mold melt inlet, such as for example a mold pour cup adapted to receive the melt from a melting crucible in the casting chamber. After the melt is cast into the hot investment mold in the vacuum casting chamber, a pressure cap is positioned in sealing engagement with the mold melt inlet, and gas pressure is introduced through the pressure cap to provide selective or local gas pressure on the melt in the mold without pressure cracking or other damage to the relatively fragile investment mold, while the casting chamber is maintained under relative vacuum or a different pressure from that in the mold.

Abstract: A product and process for making backside thinned semiconductor image sensing devices employing neutral ion beams to reduce substrate volumes so that the image sensor can be illuminated from the backside, or side opposite etched circuitry. A neutral ion beam is contained in a vacuum chamber that has a fixture for holding a semiconductor image sensor, a control mechanism for controlling the neutral ion beam via the raster mechanism, and a map of the semiconductor image sensor. The image sensor is placed on the fixture within the vacuum chamber and the neutral ion beam removes a predetermined amount of substrate from the backside of the sensor.

Abstract: A gravity latch for a swinging gates such as a corral gate or a gate on a box stall. The latch has a barrel and keeper mounted on the gate and a gate post. They are both rectangular metal tubes and inclined downwardly from the barrel to the gate at an angle of 45.degree.. The barrel and keeper have parallel rows of fastener openings through them to enable the fastening of the barrel and keeper to gates and posts of various types, including wooden and steel corral gates. A bolt for the latch is in the form of a source metal tube that slides along the barrel and the keeper. In the latched condition, it is completely enclosed within the barrel and keeper to prevent opening of the gate by an animal.

Abstract: A scanner including a source of coherent light, a radial hologon, a f.theta. lens and a target. Between the light source and the hologon there are means for forming light from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross-sectional shape of the beam radial of the axis of rotation of the hologon. Prismatic means are provided between the hologon and the lens means for so modifying the cross-sectional shape of the beam that the spot at the target station has a selected shape and orientation. This allows the shape, orientation and size of the beam on the hologon to be optimum for duty cycle of the hologon and for spot size on the target. The prismatic means allows the spot shape and orientation on target to be optimized. The prismatic means tends to introduce undesirable bow into the scan line, therefore the wavelength of the light and the grating factor (n .lambda.
