Abstract: A balancing disc or appliance for use in with a shoe insole, or biomechanical device, such as an ankle or foot brace, for balancing the gait of a user is defined by a substantially circular disc or body element having a top surface and a bottom surface. The top surface and the bottom surface are angularly inclined with respect to each other in an angle ranging from about 2° to about 6°. Optimally, an adhesive is deposited onto one of the surfaces for facilitating affixation of the disc to an insole or similar orthotic device.  The disc is, preferably, formed from a flexible material. Since the device is substantially circular in nature, it may be rotated about a vertical axis through a 360° arc to facilitate minute adjustments in the balance of the user.

Abstract: In a Reed-Solomon encoding device which produces, for example, a Reed-Solomon code of 4 bytes for a data signal of 16 bytes, the Reed-Solomon encoding device includes a signal separating circuit (100) which separates the input signal into two signals A and B which are successively outputted in a time division fashion.  In synchronism with the output of these signals, an octal counter (1) is counted up.  In response to the two separated signals outputted from the signal separating circuit (100), coefficients of respective terms of a remainder obtained by dividing the data signal by a generator polynomial  are classified into even-number order ones and odd-number order ones to be calculated in parallel. The even-number order coefficients and the odd-number order coefficients are supplied to selectors (2) and (3) as signals C and D, respectively.  The selectors (2) and (3) output the signals from the signal separating circuit (100) when the counter (1) has a count value between 0 and 5 and the signals C and D when the count value is 6 or 7.

Abstract: A radiation detector in which pri-mary electrons are released into a gas by ionizing radiations and drifted through an electric field (E) to a collecting elec-trode (CE) for detection. It further in-cludes a gas electron multiplier (10, 11, 12) formed by one or several matrices of electric field condensing areas (li) which are distributed within a solid sur-face perpendicular to the electric field. Each electric field condensing area con-sists of a tiny hole passing through the solid surface that forms a dipole adapted to produce a local electric field am-plitude enhancement proper to generate an electron avalanche from one primary electron. The gas electron multiplier op-erates thus as an amplifier or a pream-plifier within a host radiation detector.

Title: Arrangement and operation of dryer between shrinkage compactors to control residual shrinkage of knitted fabric below tumble drying
Inventor: CATALLO FRANK
IPC: F26B13/10
Filed: 2000-10-18
Granted: 2007-01-09
Abstract: Apparatus and a related method control within acceptable limits, of less than two percent(2%), residual shrinkage in garments to be made from a knitted fabric tube or open web. The apparatus and method also apply to other fabrics subject to high shrinkage. The knitted fabric is passed continuously in a moist condition through a first shrinkage compactor. Then the fabric is carried on an endless belt through a special dryer in a relaxed condition to allow loops of knits to shorten. A series of nozzles are arranged above and below the fabric in an alternating format to cause the fabric to wave in the dryer still in the relaxed condition. The web is then conveyed still in the relaxed condition to a second shrinkage range for final shrinking to a desired weight per surface area with less than two percent(2%) residual shrinkage.      Thus the garments are safe from further shrinking in home tumble dryers.
