Title: Multi-piston valve actuator
Inventor: ADAS JAMES O
IPC: F15B11/036
Filed: 2003-09-18
Abstract: A pressurized-fluid-operated actuator has multiple piston surfaces for providing increased output force. The actuator includes a stationary cylinder that contains a movable cylinder having multiple inner chambers separated by stationary inner pistons. The inner chambers are in fluid communication with extension and retraction ports provided in the stationary cylinder wall.  Introduction of pressurized fluid into one port causes the fluid pressure to act on "n" piston surface(s) to retract the movable cylinder. Introduction of pressurized fluid into the other port causes the fluid pressure to act on "n +  1" piston surfaces to provide an increased output force without increasing the diameters of the cylinders and without increasing the pressure of the fluid.

Inventor: VIGNALI DARIO A
IPC: A61K35/12
Filed: 2004-03-01
Abstract: Regulatory T cells (Treg) limit autoimmunity but can also attenuate the magnitude of anti-pathogen and anti-tumor immunity. Understanding the mechanism of Treg function and therapeutic manipulation of Treg in vivo requires identification of Treg selective receptors. A comparative analysis of gene expression arrays from antigen specific CD4+ T cells differentiating to either an effector/memory or a regulatory phenotype revealed Treg selective expression of LAG-3 (CD223), a CD4-related molecule that binds MHC class II.  LAG-3 expression on CD4+ T cells correlates with the cells' in vitro suppressor activity, and ectopic expression of LAG-3 on CD4 T cells confers suppressor activity on the T cells. Antibodies to LAG-3 inhibit suppression both in vitro and in vivo. LAG-3 marks regulatory T cell populations and contributes to their suppressor activity.

Abstract: Methods and apparatus for obtaining a digital code representative of a skin- covered body part (fingertip or other). An image of the body part is acquired, where the image includes a plurality of pixels, each pixel having an associated shade value. A plurality of subsets of pixels from the plurality of pixels is identified, with each subset including at least two pixels having a common one of a plurality of designat ed shade values. For each of a plurality of combinations of pixels taken from the pixels in the subsets of pixels, a geometric measure of the pixels in that combination is determined and then the geometric measures are encoded into a digital code for the skin - covered body part. In this way, a unique code is obtained that does not contain information about the structure of the body part, thereby alleviating privacy concerns i n applications such as access control and offender supervision.

Title: Device and method for recording information with remapping of logical addresses to physical addresses when defects occur
Inventor: BLACQUIERE JOHANNIS F R
IPC: G11B20/18
Filed: 2004-06-17
Abstract: A device for recording records information in blocks having logical addresses at a physical address (52) in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information, such as remapping tables, maintained in defect management areas. For avoiding remapping of real~ time information, such as video, a series of blocks (42) having a continuous logical address range is recorded in a corresponding allocated physical address range. In the event of a defect interrupting the allocated physical address range local offset information is generated for adding an offset to a local range of physical addresses in said address translation for skipping (61) the defect. The blocks logically following the last block before the defect are written at physical addresses following the defect, and an end portion (62) that extends beyond the allocated physical address range due to the defect, is accommodated elsewhere.

Title: Sediment removal apparatus and method for removing sediment from open waterways
Inventor: TAPLIN STEVEN B
IPC: E02B3/02
Filed: 2006-01-26
Abstract: A sediment removal system and method provides a versatile and controllable device for removing sediment from water in a focused manner that avoids generating unwanted turbidity. A suction pump draws water and sediment through a suction conduit and the injection of air into the suction conduit by air nozzles enables sediment to be removed from greater depths. The inclusion of water nozzles on an inlet opening enables hardened sediment to be dislodged such that it may be drawn into the suction conduit. A GPS receiver mounted to the suction conduit enables the location of the removal process to be tracked and a knife valve prevents backflow out of the suction conduit. The capturing of solid sediment by retention containers and the capturing of water containing suspended sediment by a tank enables the sediment and water to be transported to an appropriate location for treatment or disposal.
