Title: Method of analysing astigmatism and apparatus for performing corneal surgery
Inventor: ALPINS NOEL A
IPC: A61F9/01
Filed: 1993-03-04
Abstract: A method of analysing astigmatism is disclosed which enables surgeons to ascertain what surgery may be required subse-quent to initial surgery to achieve the preoperative aim of the initial surgery and to provide data amenable to statistical analysis which enables meaningful comparison of both multiple surgeries and techniques.  The method includes determining a preopera-tive astigmatism (1), defining an aimed astigmatism (2) and determining an achieved astigmatism (3) following initial surgery. The astigmatism values are initially determined in a 0 to 180° range and are doubled to convert them to a 360° range. An aimed induced astigmatism vector (AIA), a surgically induced astigmatism vector (SIA) and a difference vector are calculated and angle values are halved to return the angle values to a 0° to 180°  range. Magnitudes and angles of the vectors can be calculated to pro-vide astigmatism magnitude values and angle values for modifying parameters of future surgery for improved performance of fu-ture surgery and for statistical analysis. The method also provides a rationale for determining a treatment parameter when specta-cle and corneal astigmatism do not coincide.
Patent CA-2139826-A1 (CA)
Inventor: RHODES RANDEL L
IPC: A47K10/42
Filed: 1995-01-09
Abstract: A generally rectangular sheet is folded upon itself along a first crease that is parallel with two edges of the sheet.  The position of the fold is located to create a structure having a region of double thickness but in which one of the edges is offset from the other.  The folded structure is folded upon itself along a second crease that is parallel with the first crease to provide a first flap of double thickness that lies upon one surface of the structure.  The structure also is folded upon itself along a third crease that is parallel with the first and second edges and within the region of double thickness to provide a second flap lying upon the one surface.  In the totally folded sheet, the one of the edges is closer to the center of the sheet than the other edge.  A unique dispenser is provided which allows the user to grasp only the one edge so that the sheet product unfolds completely when pulled from the dispenser.

Title: Protective brace for figure skaters
Inventor: BOISCLAIR CAROLE
IPC: A63B71/12
Filed: 1995-10-23
Abstract: The present invention relates to a protective brace for use by a figure skater to prevent impact borne bone bruising resulting from one or more falls of the skater on the ice.  The brace of the invention comprises a semi-rigid,  resilient plastic shell.   The latter has a generally rectangular web defining a longitudinal axis and having two downwardly oriented, wide, curved extensions at the respective extremities of the longitudinal axis.  The shell has  a  lower and an upper tongue  integrally and orthogonally  extending  from  the middle  of  the  web respectively downwardly and upwardly.  The shell is molded to fit a particular skater, the web resting on the lombo-sacral area of the back of the skater and molded so as to position the longitudinal axis partially around the hips, the two curved extensions projecting downwardly from the hips over the thighs, the lower tongue straddling over the coccygeal  section  of  the  spine  and  the  upper  tongue extending over the lombo-thoracic section of the spine. The brace further comprises ten straps that are attached to the  shell  and  that  are  destined  to  steadfastly  and removably secure the shell adjustably to the body of the skater.   The shell is of such a shape that it does not surround significantly any body articulation,  so as to allow a relatively good freedom of movement to the skater wearing the brace.  Indeed, the only part of the brace that surrounds the articulations  is the  light,  uncumbersome straps.
