Title: Method to screen phage display libraries with different ligands
Inventor: TOMLINSON IAN
IPC: C12N15/10
Filed: 1998-10-20
Abstract: The invention provides a method for selecting, from a repertoire of polypeptides, a population of functional polypeptides which bind a target ligand in a first binding site and a generic ligand in a second binding site, which generic ligand is capable of binding functional members of the repertoire regardless of target ligand specificity, comprising the steps of: a) contacting the repertoire with the generic ligand and selecting functional polypeptides bound thereto; and b) contacting the selected functional polypeptides with the target ligand and selecting a population of polypeptides which bind to the target ligand. The invention accordingly provides a method by which a polypeptide repertoire is preselected, according to functionality as determined by the ability to bind the generic ligand, and the subset of polypeptides obtained as a result of such preselection is then employed for further selection according to the ability to bind the target ligand.

Title: Transmission path torque transducer
Inventor: EISENHAUER KARL
IPC: B62D5/04
Filed: 1998-12-15
Abstract: A torque transducer comprising a rotating shaft having first and second torque input members (1a, 1b) connected by a torsionally compliant coupling (2) thereby enabling angular deflection of the torque input members relative to each other as a function of the magnitude of the torque in the shaft. The transducer having an EMR source (5, 6) and an array or EMR sensitive detectors (7, 8). Each of the torque input members having a grating zone (101, 102) with alternating regions of high and low transmissibility to the EMR. The grating zone resides in the transmission path (90, 91) communicating EMR from the source to the array. A pattern is produced by incident EMR on the array resulting from the alternating regions of high and low transmissibility of the grating zones residing in the transmission path to the array. The pattern on the array is processed to derive the relative angular deflection of the torque members and provide a measure of the magnitude of the torque in the shaft.

Title: Temperature control safety mechanism for radio base stations
Inventor: BERGLUND BO
IPC: H04B1/036
Filed: 1998-12-15
Abstract: A method and apparatus for reducing the amount of heat generated by a base station is disclosed. The method includes measuring the temperature of the base station equipment with a temperature sensor. When the sensor detects that a first predefined temperature level is reached, a first alarm in the mobile switching center is triggered. In response, the mobile switching center blocks a first predefined number of transceivers. Similarly, if the temperature continues to rise past a second and third predefined temperature levels, the mobile switching center blocks a second and third respective predefined number of transceivers as necessary. As the temperature decreases, the mobile switching center unblocks the respective transceivers in reverse order as determined by the temperature. The technique reduces the operating temperature of the base station such that equipment failure due to excessive heat is prevented.

Title: An improved method for an authentication of a user subscription identity module
Inventor: MARCOVICI MICHAEL
IPC: G06F21/34
Filed: 2001-04-18
Abstract: A method for improving an established Authentication and Key Agreement procedure which prevents rogue mobiles from fraudulently gaining access to a communication system. The communication system periodically broadcasts a challenge interrogation message requesting that a mobile, which is currently validated to use the system, to authenticate itself to the system. The mobile computes an authentication response based on information known only to the communication system and the USIM of the mobile and transmits said response to the communication system. The communication system also computes an authentication response and compares said response with that received from the mobile. A  mobile is authenticated by the communication system when the two authentication responses are equal.      Otherwise, the mobile is not given access to the communication system.
