Title: Method for inhibiting transplant rejection
Inventor: FAUSTMAN DENISE L
IPC: A61K35/407
Filed: 2000-02-18
Abstract: A method for inhibiting rejection of tissues transplanted into a mammalian host is disclosed. Treatment of the tissues with an enzyme or combination of  enzyme, particularly papain, to eliminate cell surface structures necessary for recognition by the host's immune system, particularly MHC Class I molecules, avoids or reduces the attack of the host's immune system on the transplanted tissues. Tissues that are enzymatically shaved of MHC Class I antigens and/or other critical adhesion molecules can be rendered at least temporarily resistant or immune to attack by cytolytic T lymphocytes, helper  T lymphocytes, antibodies, or other effector cells of a host's immune system, thereby enhancing the survivability of the tissues in the host after transplant.

Title: Detection and correction of defects from scanner calibration references
Inventor: ROMBOLA GREGORY
IPC: H04N1/19
Filed: 2001-05-16
Abstract: Computation of digital gains and offsets used in digital scanners for shading correction (linearity correction) is particularly vulnerable to imperfections in the reference strips, particularly the light reference strip. It is extremely difficult and expensive to create references (133, 203) which are completely free of imperfections or contaminated in some way. This invention eliminates artifacts caused by the presence of small imperfections on the references. It does so by detecting the presence of an artifact (133, 134) and then excluding data contributed by the artifact from the calibration computation process.

Inventor: GERKIS ANTHONY
IPC: H04L12/56
Filed: 2002-07-08
Abstract: A system, method and apparatus for managing uplink radio resources. The RRAM employs selective rate reduction to ensure resources for subscriber stations depending on individual QoS requirements. In response to a request for a new DDCH, the RRAM  can drop a subscriber station at a low data rate and no media reservations. In response to traffic measurement reports from the subscriber stations, the RRAM attempts to increase or decrease the data rate of a subscriber station. When there are insufficient uplink resources, RRAM tries to lower the rate of a higher rate subscriber station. Searching for subscriber stations to lower, RRAM starts at the highest rate and continues to search lower data rates until a suitable candidate is found. RRAM also reserves resources for subscriber stations that will not be reallocated to other subscriber stations.

Title: Biosensor and deposit sensor for monitoring biofilm and other deposits
Inventor: BOETTCHER HELMUT
IPC: G01N17/00
Filed: 2001-06-14
Abstract: A method and apparatus for determining the deposition of organic and inorganic contaminants, such as biofilm, on a coupon is disclosed. The method and apparatus include a coupon suspended from a weight sensor within a reservoir tank. The reservoir tank includes fluid inlet means for receiving a fluid sample which flows over the surface of the coupon for a determined period of time to allow contaminants presents in the fluid sample to deposit on the coupon surface. At regular intervals, the reservoir tank is drained and the coupon is allowed to dry and is weighed. The weight of the contaminants which have deposited on the surface of the coupon is determined by comparing the weight of the coupon to its previous weight. In this manner, a computer system attached to the weight sensor can analyze a series of weights and present the results in a time-deposit graph. The present invention can be fully automated to allow for effective and optimal biocidal whitewater treatments to occur in pulp and papermaking processes, and is well suited for use in screening biocidal agents effective in preventing the deposition of contaminants on equipment surfaces.
