Title: Long jump and triple jump foul detector system
Inventor: BEDNARZ JOHN
IPC: A63B5/00
Filed: 1991-12-04
Abstract: ABSTRACT       A long or triple jump foul detector system is disclosed which very accurately detects a foul by an athlete when a portion of an athlete's shoe crosses over a foul line when beginning the jump. A laser beam is emitted parallel to and directly above the foul line.  A laser beam detector detects interruption of the laser beam by the athlete's shoe and a foul detector provides a foul indication.  An audible foul indication is delayed so as not to interfere with the athlete's jump.          Also,  the  system  may  provide  additional  detection  of  an athlete's foot crossing a training line positioned in front of the foul line.  Furthermore, the system distinguishes between a relatively  quick  interruption  of  the  beam  caused  by  the athlete's shoe when jumping, and a relatively slow interruption of the beam which may result such as by a judge placing his or her hand in the beam when measuring a jump.   The system is equally well adaptable to either indoor or outdoor long or triple  jump  competition,  and  includes  convenient  set-up procedures which ensure accuracy.  The system also automatically compensates for varying light conditions and is effective in bright sunlight.  When a low battery voltage condition arises, the system automatically alerts the operator.  A micro-processor is employed for rapid and accurate control of the various functions performed by the system.

Patent CA-2060119-A1 (CA)
Title: Method and apparatus for detecting ions and small molecules in aqueous and non-aqueous liquids
Inventor: BAKER MARK D
IPC: G01N27/49
Filed: 1992-01-28
Abstract: Provided is a method and apparatus for detecting electroinactive ions, and electroinactive ions solvated by small molecules including water. The method and apparatus utilizes a microporous ion exchange material such as a zeolite containing initially an electroactive species contained within the pores. The method operates on the principle that when charged species present in solution can access the pores of the micro porous material, an ion-exchange reaction will occur whereupon the electroactive species will exit the micro porous material, being replaced by the charged species. The electroactive species, upon exiting the microporous material, undergoes electrochemical reduction or oxidation at an electrode having a sufficiently high potential applied thereto. The method and detector disclosed herein is size selective since for example zeolites with a pore size comparable to that of the solvated ion to be detected but smaller than other electrolyte components can be utilized. In addition to being used as an ion detector per se, the detector may be used for detecting trace amounts (sub parts per million) of water in non-aqueous media by using the fact that hydrated ration species can readily access the zeolite interior via the pore network thus expelling an electroactive ion into solution. In contrast, the same ration when solvated by organic molecules will be size excluded from the zeolite. The detector can be utilized for the detection of other small molecules using the same principle provided that they form a solvated complexes with electrolyte canons which are not size excluded from the zeolite.

Filed: 1992-04-15
Abstract: Fault tolerance in a redundant array of disk drives is degraded when error conditions exist in the array. Several methods  for  rebuilding data  of  the  array  to remove the degradation are described.   Data rebuilding for entire disk drives and partial data rebuilds of disk drives are described.  All rebuild methods tend to reduce the negative affect of using array resources for the data rebuild.   In one method rebuilding occurs during idle time of the array.   In a second method rebuilding is interleaved   between   current   data   area   accessing operations of the array at a rate which is inversely proportional to activity level of the array.  In a third method,  the data are  rebuilt when a data  area being accessed is a data area needing rebuilding.
