Title: Yeast cell surface of proteins having enhanced properties
Inventor: BODER ERIC T
IPC: C12N15/81
Filed: 1999-01-20
Abstract: The present invention provides a genetic method for tethering polypeptides to the yeast cell wall in a form accessible for binding to macromolecules. Combining this method with fluorescence-activated cell sorting provides a means of selecting proteins with increased or decreased affinity for another molecule, altered specificity, or conditional binding. Also provided is a method for genetic fusion of the N terminus of a polypeptide of interest to the C-terminus of the yeast Aga2p cell wall protein. Attaching an scFv antibody fragment to the Aga2p agglutinin effectively mimics the cell surface display of antibodies by B cells in the immune system for affinity maturation in vivo. T cell receptor mutants that are efficiently displayed on the yeast cell surface can be isolated by this method, providing a means of altering T cell receptor binding affinity and specificity by library screening. The selection method also identifies proteins with enhanced phenotypic characteristics, proteins that are displayed at higher levels, proteins that are secreted at higher efficiency and proteins that are more stable.

Abstract: This invention relates to a device for retaining bait on a fishing hook. More specifically, it relates to a device comprised of a body of resilient material constructed so as to be pierced by an end of a fishing hook and pushed down the hook, after the bait has been placed on the hook, to a position proximate to the bait. The device therefore serves to retain the bait on the hook by frictionally engaging the hook in order to prevent accidental disengagement of the bait.

Abstract: A service sign-on method for a network having a connectionless protocol provides user authentication, controlled access to network services, and facilitates network utilization records keeping. The network has a user subnetwork to which an access device is coupled, a management subnetwork, a service subnetwork and a router through which the user subnetwork may selectively communicate with the management subnetwork and the service subnetwork. The router is initially implementing a policy to block communication from the user subnetwork to the service subnetwork. The method being performed by a processor coupled to the management subnetwork, includes the steps of (a) obtaining a username from the access device; (b) verifying authenticity of the username; and (c) if the username is authenticated, activating a policy in the router to permit communication associated with the username to proceed through the router to the service subnetwork. The management network may include a DHCP server. The service network may include a DNS server and an internetwork device that provides user access to the Internet. The method may further include registering a MAC address and access policy rule set with the DHCP server requiring lease renewal, downloading a renewal process to the browser, creating a session identifier and passing it to the browser in a message, for example, as a cookie, validating an access policy on the internetworking device via SNMP commands or other IETF protocols, and maintaining session accounting with a timestamp that may expire a keep-alive communication is not timely sent.

Title: Apparatus for determining failure of electromagnetic clutch
Inventor: NIHANDA NORIHISA
IPC: G01R31/06
Filed: 2001-03-05
Abstract: There is provided an apparatus for determining a failure of an electromagnetic clutch, which is capable of properly determining whether or not a failure, a typically a layer short-circuit, has occurred due to a change in a resistance value of a solenoid coil of the electromagnetic clutch. The electromagnetic clutch is configured such that the engagement force thereof is varied according to an amount of current flowing through the coil. An output control value for control of the amount of current is calculated by feedback control such that an actual amount of current actually flowing through the coil becomes equal to a desired amount of current. A predetermined reference control value is stored which defines a standard for the output control value and has a standard relationship with respect to the amount of current. The actual amount of current is detected. The calculated output control value is compared with the predetermined reference control value corresponding to the detected actual amount of current . It is determined based on a result of the comparison by the comparison means whether or not the electromagnetic clutch has failed due to a change in a resistance value of the coil of the solenoid thereof.

Title: Self-expanding defect closure device
Inventor: FARNAN ROBERT C
IPC: A61M31/00
Filed: 1999-06-10
Abstract: The present invention relates to a self-expanding device for sealing a defect in a wall, such as a septal defect. The device of the present invention has a helical shaped periphery formed from an elastic wire and at least one eyelet. The eyelet has a non-circular ("asymmetric") shape which allows the eyelet to slide along a guiding mandrel. The non-circular shaped eyelet and mandrel prevent rotation of the eyelet relative to the mandrel thereby ensuring a consistent deployed shape. The present invention also incorporates a self-articulating catheter tip which can be bent to a variety of angles to enhance the ease of delivery.  The tip is articulated by varying the position of the closure device within the articulated portion of the catheter.

Title: Waterproof system for delivering light to a light guide
Inventor: BUELOW ROGER F II
IPC: F21S8/00
Filed: 2001-03-30
Abstract: A light delivery system includes a light source. A first generally tubular, hollow coupling device with an interior light-reflective surface receives light from the source at an inlet and transmits it to an outlet. The coupling device increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member, the thermal-isolating region comprising one or more members. A waterproof container for the light source and coupling device has an aperture allowing light to pass out of the container. The aperture is sealed in part by a portion of a member of the thermal-isolating region. Advantageously, the system can be buried beneath the surface of the ground.  This avoids the problem of people or equipment colliding with the system. The components in the sealed container are protected from intrusion by wildlife or deterioration from dirt and dust. In some embodiments, the container may be free of a fan, reducing the complexity and noise of the system.

Title: Pop-in extended travel single roller for patio doors
Inventor: BECKEN DONALD A
IPC: E05D15/06
Filed: 2001-06-11
Abstract: The invention consists of a pop-in extended travel single roller for patio doors. This roller assembly is retained in the patio door track by no mechanical means. This is accomplished by mounting the roller assembly into a pre-fabricated opening, the width of which is slightly larger than the over-all basic width of the outer housing. Protrusions on the side of the outer housing, after passing through the opening, retain the roller in the proper position. This feature eliminates the need for mechanical fasteners thereby saving costs of parts and labor. This assembly also provides for increased over-all height adjustment range. Finally, this invention through the use of an adjusting screw aids the ease of removal of the movable panel of the patio door assembly.
