Title: Method of and structure for the joining of substantially rigidparts together
Inventor: MENGEL CRAIG
IPC: A47B47/04
Filed: 1987-07-24
Granted: 1992-03-24
Abstract: METHOD OF AND STRUCTURE FOR THE JOINING OF SUBSTANTIALLY RIGID PARTS TOGETHER          ABSTRACT OF THE DISCLOSURE         Conventionally, substantially rigid parts such as panels and the like, are joined by mechanical fitments or couplers which not only require tools to assemble and disassemble but also create concentrated stress points at the junctions where the fitments or couplers are located. The present device utilizes hook and loop coupling mate-rial to detachably secure the parts together and incorpo-rate mechanical location and aligning means between the two parts just prior to the engagement of the hook and loop fastener portions with one another thus facilitating the accurate assembly of the parts.   Although designed primarily for use in various types of knock-down furni-ture and the like, it can of course be adapted for use with other substantially rigid parts.

Title: Blood pressure monitoring method and apparatus
Inventor: ECKERLE JOSEPH S
IPC: A61B5/02
Filed: 1987-12-08
Granted: 1992-06-30
Abstract: ABSTRACT          Intraarterial blood pressure is measured noninvasively by an electromechanical transducer.  The correct hold-down force to be applied to the transducer for obtaining accurate blood pressure measurements is determined by obtaining a set of at least one of the diastolic pressure, systolic pressure, and pulse amplitude versus hold-down pressure values over a range of hold-down pressures between which the underlying artery is unflattened and it is occluded.  A polynomial is fitted to at least one of the sets of values, from which polynomial the correct hold-down pressure is determined.  The hold-down pressure at the point of minimum slope of graphs of the polynomials fitted to the systolic and diastolic versus hold-down pressure values provides an indication of the correct hold-down pressure.   An indication of  the  correct hold-down pressure using the pulse amplitude measurements is provided by locating the midpoint of a pair of hold-down pressures at which the pulse amplitude is substantially sixty percent of the maximum pulse amplitude on the graph of the polynomial fitted to the pulse amplitude versus hold-down pressure values. An alternative method determines the correct hold-down pressure directly from the pulse-amplitude polynomial coefficients. A measure of the compliance of the underlying artery is obtained from the ratio of the minimum slope of the graph of the polynomial fitted to one of the systolic and diastolic versus hold-down pressure values to the slope of a straight line fitted to a subset of one of the systolic and diastolic versus hold-down pressure values over a range of hold-down pressures below which flattening of the underlying artery occurs.

Title: Method and apparatus for fingerprint verification
Inventor: TOMKO GEORGE J
IPC: G06V10/88
Filed: 1987-12-22
Granted: 1991-10-29
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to an optical processing finger-print verification device.  A light source illuminates a prism upon which the user has placed two fingers so that light reflected from the prism is modulated by the data of the users fingerprints.          The fingerprint data beam passes through a lens and undergoes a Fourier transform at a card including a reflection hologram matched to two fingerprints of a reference individual.  The inten-sity distribution of the light reflected from the hologram deter-mines whether a match exists.  Use of a reflection hologram allows use of an incoherent light source.  The two fingers are located on the prism by movable guides positioned by information on the card as to the relative length and the width of the two fingers of the reference individual.  This provides a second level of verifica-tion.  Scaling sensitivity may be reduced by utilising a frequency multiplexed hologram.

Title: Method for measuring edge profile of an elongated member
Inventor: WASHBURN STEVEN L
IPC: G01B11/245
Filed: 1988-06-08
Granted: 1993-09-07
Abstract: METHOD FOR MEASURING EDGE PROFILE OF AN ELONGATED MEMBER                    ABSTRACT OF THE DISCLOSURE The present invention is a method of determining edge profile of one or both edges of an elongated member such as a piece of lumber or structural timber. This can be done at high speed as the member is conveyed past a scanning station where it is subject on the conveyor to translational and/or rotational movement relative to a baseline. The baseline is located generally parallel to the longitudinal axis or centerline ofthe member. At the leading end of the member the instantaneous edge height above the baseline is measured at three spaced apart locations. These measurements are continued along the member with each sampled portion substantially overlapping the previously sampled portion. For each individual sampled portion any deviation from linearity of the edge at the interior measurement position is determined from a chord drawn between the end measurement positions. Knowing these deviations the edge profile can be readily computed for the member. This is most readily done by dividing twice each deviation by the square of the distance between adjacent scanning positions to obtain a second derivative of the edge contour at the measured location. The overall edge contour is then obtained by double integrating the second derivatives obtained over the length of the measured member.

Abstract: ABSTRACT OF THE DISCLOSURE       A wheelchair with at least one electrically driven drive wheel, with a pair of power-steered steering wheels which can each be turned around an essentially perpendicular steering axis, and with a steering element to be activated by hand.  Each steering wheel has its own steering motor for the adjustment of the steering angle of the steering wheels around the steering axis.  The steering element is a mechanical-electrical steering angle transmitter, from which an electrical steering signal dependent on the angle position of the steering element is derived, which is fed into an electrical device, which, for the control of both steering motors for the adjustment of the steering angle of the steering wheels in regard to their steering axis, produces two adjustment signals, which are inversely proportional to the curve of radius.  The steering angle can amount to up to 360°, through which a substantial manoeuvrability is provided.  The steering angles nevertheless always precisely satisfy the laws of steering, so that a lateral jamming of the steering wheels and an increased wear on the tires of the same is thereby avoided.
