Title: Method and apparatus for detecting eye location in an image
Inventor: SWAIN CASSANDRA TURNER
IPC: G06T7/00
Filed: 1998-04-27
Granted: 2001-10-30
Abstract: Method And Apparatus For Detecting Eye Location In An Image A simple method for segmenting eyes and extracting parameters enables further processing of the image to enable a person to appear to be making eye contact with another via a video conferencing system. This method is a first step for eye synthesis and gaze detection because it can automatically extract select eye parameters useful to these processes. Its advantage is that no a priori information is necessary to segment eyes, unlike modeling and neural network methods. The method of the present invention first blurs the image to make it easier to determine the location of the two eye regions in the image. The eyebrows are then eliminated based on the located eye regions. The eyes are thensegmented and the eye parameters are extracted from the resulting image. According to the present invention, the process applies a Gaussian filter, h(~,.gamma.),where g(~,.gamma.) is the resulting image and(~,.gamma.) is the original image.

Title: Method and system for high resolution ultrasonic imaging of small defects or anomalies
Inventor: LEVESQUE DANIEL
IPC: G01N29/46
Filed: 1999-07-13
Granted: 2003-02-18
Abstract: A method and system is provided for enhanced ultrasonic detection and imaging of small defects inside or at the surface of an object. The Synthetic Aperture Focusing Technique (SAFT) has been used to improve the detectability and to enhance images in conventional ultrasonics and this method has recently been adapted to laser-ultrasonics. In the present invention, an improved version of the frequency-domain SAFT (F-SAFT) based on the angular spectrum approach is described. The method proposed includes temporal deconvolution of the waveform data to enhance both axial and lateral resolutions, control of the aperture and of the frequency bandwidth to improve signal-to-noise ratio, as well as spatial interpolation of the subsurface images. All the above operations are well adapted to the frequency domain calculations and embedded in the F-SAFT data processing. The aperture control and the spatial interpolation allow also a reduction of sampling requirements to further decrease both inspection and processing times. This method is of particular interest when ultrasound is generated by a laser and detected by either a contact ultrasonic transducer or a laser interferometer.

La substance contenant l'agent blanchissant est appliquée sur la bande de matière de façon que lorsque le système d'administration entre en contact avec la surface des dents, ladite substance entre en contact avec la surface des dents et délivre le principe actif sur cette surface. Ladite substance permet également la fixation adhésive de la bande de matière à la surface des dents, ce qui assure le maintien du système d'administration pendant un laps de temps suffisant pour que le principe actif agisse sur ladite surface. Le procédé d'administration consiste à pré-enduire la bande de matière de cette substance ou à faire appliquer cette substance sur la bande par l'utilisateur, puis à appliquer le système d'administration à la surface des dents.

Granted: 2009-02-03
Abstract: A safety locking coupling assembly in which pull rings on the female coupling unit of a male coupling unit/female coupling unit assembly serve both to release the coupling assembly and to maintain the coupling assembly locked against unintentional disconnection.  The pull rings are attached to cam arms which engage the male coupling unit to lock the coupling assembly and are disengaged from the male coupling unit to release the coupling assembly. In the locked condition of the coupling assembly, the pull rings abut against ears on the housing of the female coupling unit to oppose unintended movement of the cam arms from the locked position of the cam arms to the released position of the cam arms. Upon intentional removal of the pull rings from abutment with ears by an operator and pulling on the pull rings, the cam arms can be moved from the locked position of the cam arms to the released position of the cam arms to disconnect the coupling assembly.
