Patent CA-2332712-C (CA)
Title: Two-axis cursor control apparatus
Inventor: YU YAT SHUN DAMIEN
IPC: G06F3/0354
Filed: 2001-01-29
Granted: 2006-07-11
Abstract: A reduced-size cursor control apparatus includes a spherical ball; two rotors in contact with the spherical ball and two corresponding axles; two screw devices associated with each rotor-axle pair, each screw device having a continuous helical thread; and a plurality of light sensors, each associated with a screw device.  When the spherical ball is rotated by the user, its motion about each axis of rotation is translated to one of the screw devices by means of the corresponding rotor-axle pair. The rotation of the screw devices causes the helical thread on each to momentarily interrupt the light beam generated by each sensor at least once during each revolution of the screw device, thereby generating a signal which is translated into two-dimensional motion of a cursor on an electronic display screen.

Patent CA-2336330-C (CA)
Inventor: RITTLE LOREN J
IPC: H04B7/26
Filed: 1999-06-08
Granted: 2005-05-24
Abstract: A communication device employs a method and apparatus for transmitting and receiving information packets using multiple layers of error detection. A sending communication device constructs an information packet to include user information divided into multiple data blocks, a primary error detection code for each data block, and at least a portion of a secondary protection code. The secondary protection code provides error protection for the entire information packet. The secondary protection code is selected such that it can be incrementally determined by a receiving device as data blocks are received and accepted by the receiving device, regardless of order of reception of the data blocks. Since the secondary protection code is incrementally determined, processor utilization is better regulated and delays associated with sending acknowledgments are minimized.

Ce procédé consiste à générer un faisceau (10) d'excitation laser (p. ex. d'une longueur d'ondes de 700 nanomètres à 900 nanomètres) à diriger (13) ce faisceau d'excitation dans la chambre antérieure de l'oeil du sujet de manière à éclairer l'humeur aqueuse dans la chambre antérieure d'un oeil, à détecter (32) (de préférence de manière confocale (22)) un spectre Raman à partir de l'humeur aqueuse éclairée, puis à déterminer le taux de glucose (ou le taux d'un autre composé à analyser) dans le sang du sujet à partir du spectre Raman. L'étape de détection est suivie de préférence par une étape consistant à soustraire un spectre de fluorescence confusionnel du spectre Raman afin de produire un spectre différentiel puis à déterminer le taux sanguin d'un composé à analyser chez un sujet à partir de ce spectre différentiel, de préférence au moyen d'une analyse multidimensionnelle linéaire ou non linéaire telle qu'une analyse partielle par les moindres carrés. L'invention concerne également un dispositif permettant d'appliquer ce procédé.
