Title: Optical peristaltic pumping with optical traps
Inventor: GRIER DAVID G
IPC: G21K1/00
Filed: 2002-06-06
Granted: 2008-10-21
Abstract: A method of use for holographic optical traps or gradients in which repetitive cycling of a small number of appropriately designed arrays of traps are used for general and verycomplex manipulations of particles and volumes of matter. Material transport resultsfrom a process resembling peristaltic pumping, with the sequence of holographically-definedtrapping or holding manifolds resembling the states of a physical peristaltic pump.

Abstract: L'invention concerne le traitement d'appels multimédia dans un réseau à commutation par paquets. Ce traitement met à profit un traitement de modèles d'appel existant en continuant à utiliser des modèles d'état d'appel de base (542) afin de commander l'appel général à deux abonnés et à utiliser des visualisations de connexion (550) pour associer plusieurs appels à deux abonnés et permettre d'accéder aux services complémentaires avancés. Grâce à un processeur de visualisations multimédia (552), le système sépare la gestion des connexions multimédia de la gestion des appels. Les modèles d'appel de base (542) sont élargis de façon qu'ils supportent de nouveaux messages et des messages améliorés afin de créer, de modifier et d'effacer des objets de visualisation multimédia et de transmettre ces modifications aux flux multimédia entre les processeurs de modèle d'état d'appel (524) et des processeurs spécifiques de protocole (522).

Abstract: Core orientator (10) for a core drill (24) includes a face orientator (28) and a bottom orientator (30) supported by a shaft (50) which extends into a shroud (86). A tubular extension (90) is coupled to the shroud (86) and is slidably coupled to a main body (12). The main body (12) includes first and second latches (16) and (18). The first latches (16) releasably lock the device (10) to a core lifter case assembly (20) disposed within the core drill (24), to selectively prevent the device (10) from advancing in an uphole direction within the core drill (24). The latching system (18) operates to prevent the device (10) from falling out of the core drill (24). Face orientator (28) includes a plurality of pins (32) which can move axially to provide a plurality of profile reference points to a facing surface of a hole to be drilled. The bottom orientator (30) includes a plurality of balls (60) disposed within said respective braces (62). In initial operation, the device (10) is loaded into the core lifter case assembly (20) with the latches (16) abutting a forward most end of the assembly (20). Pins (32) are extended to the maximum extent out of shroud (86) and the balls (60) are able to rotate freely within the races (62). When the core drill (24) is brought into contact with the facing surface of the hole, the pins (32) are pushed backward to provide a profile of the facing surface until the shroud (86) contacts the facing surface. Then the shroud (86) is pushed in the uphole direction causing the tubular extension (90) to slide into the body (12). This releases a spring (132) causing the shaft (50) to clamp the races (62) to hold the ball (60) in a particular position commensurate with the bottom of a hole being drilled.  The latches (114) are also released by the sliding motion of the extension (90) allowing the assembly (10) to be pushed into the core tube assembly (20) and associated core tube (22). The device (10) can be withdrawn with the core in a conventional manner to provide an indication of the orientation of the core.

Title: Probe correction for gene expression level detection
Inventor: ZOU GUANGZHOU
IPC: G16B25/20
Filed: 2003-01-17
Granted: 2012-03-06
Abstract: Individual probes on micro-arrays are re-scaled and corrected with a set of probe dependent coefficients derived from genomic-DNA hybridization signals. A dynamic range for gDNA binding is determined by measuring a concentration signal curve. Signals for each probe are measured during multiple hybridizations within a linear range. Concentration insensitive probes are then found for two sets of experiments. Probes are discarded based on a threshold compared to their standard deviation divided by their average in each set. The correction coefficients are used to calculate a corrected intensity for each probe. Probes having high uncertainty (0.5 in one embodiment) are discarded. A weighting factor for each probe is determined along with an uncertainty factor. Finally, a call for each gene is made, such as absent, marginal or present.

Abstract: A method for detecting echo path changes in an echo canceller using the statistics of the echo canceling behavior (i.e. signal and performance information), to distinguish between new line and double talk conditions. A moving counter is incremented or decremented based on monitored levels of ERL (Echo Return Loss), ERLE (Echo Return Loss Enhancement), noise and signal energies. When the counter reaches a predetermined threshold value indicative of sustained poor echo cancellation performance, a determination is made that there is a probable new line condition (i.e. echo path change). This echo path change information is then passed to the echo canceller to enable re-convergence.

Abstract: A centrifugation device comprising a combined sample chamber and slide holder adapted to be mounted, with a microscope slide (26), in a centrifuge in a predetermined position, after placing a fluid biological sample containing cells in the sample chamber. The device comprises an integrally moulded body (10) affording a base (14) which engages the microscope slide, and also affording a back plate (14) connected with the base plate by an integral hinge (22) a latch mechanism formed integrally with the remainder of the device is arranged, when the back plate (14) is closed against the rear of a microscope slide (26) engaged with the base (14), to locate the slide between the base and the back plate and to hold the back plate in this closed position until fracture of a retaining element from the integrally moulded body. Thus, the device can be used once only. The base includes an aperture communicating with the sample chamber and carries an elastomeric gasket (26) for sealing the edges of the aperture with respect to the surface of the microscope slide. The material of the gasket (20) includes an oil component which, in use, forms an oil film on the microscope slide where the gasket contacts the slide, which can act as a barrier to aqueous fluid and prevents migration of such fluid past the region of the slide contacted by the gasket.

Abstract: A self-healing cement system includes cement, water and at least one additive that swells in contact with water from reservoir or from formation in the case of a structural failure in the set cement to provide a physical barrier in the zone of failure. Examples of such material include particles of super-absorbent polymer. These additives have the effect of making the cement self~healing in the event of physical failure or damage such as micro-annuli.  The self healing property is produced by the contact of the water itself, the potential repair mechanism is thus activated if and when needed in case of start of loss of zonal isolation. Several super-absorbent polymers have been identified such as polyacrylamide, modified crosslinked poly(meth)acrylate and non-solute acrylic polymers.
