Abstract: L'invention porte sur un procédé et un dispositif de forage dirigé d'un trou (3), et en particulier de forage de trous incurvés d'exploration et d'exploration à flanc de coteau ou similaire. A cet effet on utilise un support de forage (4) en forme de tube flexible continu présentant une extrémité distale et une extrémité proximale, dont la pointe de l'extrémité distale est reliée à une unité de fond de puits (5) comprenant un trépan, et qui permet de former un train de tiges (13) qui avance dans le forage en progression. Pour éviter ou réduire la survenue de broutage" pendant le forage dirigé, le support de forage (4) est fixé par son extrémité proximale pour l'empêcher de tourner hors du forage tandis que s'effectue le mouvement de rotation du trépan autour d'un axe s'étendant en direction du forage dans la zone séparant l'extrémité distale du support de forage, du trépan, alors que le forage progresse.

Title: Authentication method
Inventor: LINDHOLM FREDRIK
IPC: H04L29/06
Filed: 2003-04-16
Granted: 2012-10-23
Abstract: The invention relates to password-based authentication in group networks. Each device (42) has an authentication token irreversibly based on the password. The authentication involves a first device (42-1) at which the password P is entered and a second device (42-2) towards which the authentication occurs. The first device determines a check token Mj for the second based on the password and its own authentication token RI and this check token is sent to the second device, where it is compared with the athentication token of that device. The procedure may include update of a device to exclude a non-trusted device from the group or change the password. Advantageous features are that the information in one device does not allow retrieval of the password and that the password is only exposed at one device, and only temporarily, during the authentication.

Abstract: A system and method for eye gaze tracking in human or animal subjects without calibration of cameras, specific measurements of eye geometries or the tracking of a cursor image on a screen by the subject through a known trajectory.  The preferred embodiment includes one uncalibrated camera for acquiring video images of the subject's eye(s) and optionally having an on-axis illuminator, and a surface, object, or visual scene with embedded off-axis illuminator markers. The off-axis markers are reflected on the corneal surface of the subject's eyes as glints. The glints indicate the distance between the point of gaze in the surface, object, or visual scene and the corresponding marker on the surface, object, or visual scene. The marker that causes a glint to appear in the center of the subject's pupil is determined to be located on the line of regard of the subject's eye, and to intersect with the point of gaze. Point of gaze on the surface, object, or visual scene is calculated as follows.  First, by determining which marker glints, as provided by the corneal reflections of the markers, are closest to the center of the pupil in either or both of the subject's eyes. This subset of glints forms a region of interest (ROI). Second, by determining the gaze vector (relative angular or cartesian distance to the pupil center) for each of the glints in the ROI. Third, by relating each glint in the ROI to the location or identification (ID) of a corresponding marker on the surface, object, or visual scene observed by the eyes. Fourth, by interpolating the known locations of each these markers on the surface, object, or visual scene, according to the relative angular distance of their corresponding glints to the pupil center.
