Granted: 1991-12-10
Abstract: METHOD AND APPARATUS FOR VOICE DETECTION   HAVING ADAPTIVE SENSITIVITY                      Abstract This invention enables voice energy to be distin-guished from energy due to other sources such as telephone call progress signals.  A portion of the audio spectrum is divided into a high and into a low frequency band and the energy content of these bands is examined.  The audio energy of a signal is passed through a set of filters and compared.  A frequency boundary crossing of an input signal subsequent to filtering is used to signify the receipt of a voice signal.  By operating in this manner, voice,  whose predominant frequency switches in a random fashion from being greater than to less than a cutoff frequen-cy, can be distinguished from other signals either below or above the cutoff frequencies of the filters. The detection of voice energy is not begun until a predetermined threshold of energy has been received for a specified period of time.  This specified period of time need not be continuous after a ringback signal is received.  Subsequent to the receipt of a ringback signal  the voice detection mechanism will proceed as long as the total time above the threshold exceeds the specified time.

Granted: 1991-02-19
Abstract: ABSTRACT        A portable unloader for a truck bed includes a gate entrained on a pair of cables so that it can be pivoted to and from a first raised position in which it is inclined with respect to the truck bed as it moves toward the rear of the truck bed, and a second position in which it lies substantially parallel to the truck bed as it moves through the load along the truck bed.          In one form of the invention, the cables pass through slots near the lower edge of the plate, and the gate is secured near  its opposite edge by restraining chains attached to the cable to limit the angle at which the gate is inclined with respect to the truck bed.  Such a gate can also include a pair of wedge-shaped runners for initially orienting the gate at a slight angle to the truck bed so that a portion of the load of granular material is forced under the gate to lift it to its raised position as movement toward the rear of the truck is initiated.  In another form of the invention, the gate is pivotally secured to a sled which slides along  the  truck  bed.    The  sled  includes  upright supports pivotally securing the upper edge of the plate forming the gate above the truck bed.   The sled can also include a supplemental pivoting gate secured to the  forwardmost  end  of  the  sled  to  traverse  the forwardmost portion of the truck bed.

Abstract: Abstract of the Disclosure A chemical pulping process comprising: partially defiberizing wood chips such that the fibers in said chips are substantially  separated from one another but sufficient interfiber bonding is maintained to preserve chip integrity and thereby provide   chips having an open porous fibrous network; and subjecting said partially defiberized chips to chemical pulping at elevated temperature to remove a majority of the lignin in said chips.

Title: Hole centration gage
Inventor: BARTON RICHARD O
IPC: G01B11/00

Abstract: ABSTRACT An apparatus for measuring the relative positions of hole patterns is disclosed wherein two or more fiber optic bundles disposed within first and second holes and connected to one or more sources of light and light sensitive, position sensing devices provide two, three, four or five axis measurements of the relative positions of the two holes.  By measuring the position of the light from the source transmitted via an optical bundle in the first hole and received by an optical bundle in the second hole, a precise measurement system that senses mismatch and the direction thereof with a very high degree of accuracy is achieved.  The movement of plane surfaces may also be measured with the present apparatus by attaching either the transmitting or receiving side of the apparatus to a part which is subjected to a load, and measuring the resulting change in the position of the light beam illuminating the light sensitive, position sensing device.

Abstract: Abstract An article of manufacture comprises a molded-plastic fitment such as one of the halves of a snap fastener molded in situ to a porous substrate such as a garment fabric.  various embodiments are described for the article, as well as dies for forming the same, and methods and a machine for making the same.  The article of manufacture consists of a functional plastic component locally molded to one side of a substrate with the plastic material of the component extending integrally through and impregnating the pores of the substrate at the locality of the component.  The structures obtained by compressive deformation of a plastic pellet in contact with the substrate under such ultrasonic modulation of continuous force normal to the substrate as to create many point contacts each of which acts as a small area of energy focus for local initiation of progressively melting the pellet.
