Title: Method and system for performing a boolean operation on bit strings using a maximal bit slice
Inventor: MARQUIS JEAN A
IPC: G06F7/38
Filed: 1996-11-18
Granted: 2006-08-01
Abstract: A system (10) and a method for performing a boolean operation on bit strings to form a resultant bit string. Each bit string is divided into input bit slices. The resultant bit string is divided into resultant bit slices. An action is based on a first input bit slice from a first bit string and on a second input bit slice from a second bit string. The input bit slice with a longer bit length is selected from between the first and the second input bit slices. The longer input bit slice and a plurality of the input bit slices in the bit string having the input bit slice with shorter bit length are processed according to the action for up to a number of bits in at least one bit string equaling the longer bit length to form at least one such resultant bit slice.

Granted: 2009-09-22
Abstract: L'invention concerne un procédé de préparation microbienne d'aminoacides, selon lequel l'activité de vecteurs de transport et/ou l'expression de gènes de transport d'un micro-organisme produisant l'aminoacide correspondant sont accrues. Selon l'invention, il a été démontré que seul un gène spécifique est responsable du transport d'aminoacides. L'invention permet donc de mettre pour la première fois à disposition un procédé de préparation microbienne d'aminoacides, selon lequel l'expression de gènes de transport et/ou l'activité de vecteurs de transport d'un micro-organisme produisant l'aminoacide correspondant peuvent être accrues de manière ciblée. L'expression ou l'activité accrue du vecteur de transport, qui en résulte, entraîne un taux de sécrétion plus élevé permettant d'augmenter la vitesse de transport de l'aminoacide correspondant.
Patent CA-2242150-C (CA)
Title: Display techniques for three dimensional virtual reality
Inventor: CARRARO GIANPAOLO U
IPC: G06T15/10
Filed: 1998-06-30
Granted: 2005-09-06
Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen is that when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, namely, any portion of the object that is no longer on the video screen disappears. To overcome this limitation, when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, such an object, or portion thereof, is made to continue to be visible to the user by representing it at the foreground location to which its trajectory was carrying it using computer graphic techniques, rather than video. Thus, the video object "pops" out of the video and becomes visible, e.g., in front of, or to the side of, the video screen, rather than becoming invisible because it is no longer on the video screen.
