Filed: 1997-03-20
Granted: 2009-08-04
Abstract: The invention provides a method of determining whether a peptide of a protein is a cryptic peptide, which method includes the steps of i) exposing T cells with the peptide in a primary challenge; ii) measuring the reactivity of T cells with the peptide in the primary challenge of step i); iii) exposing pre-challenged T cells with the peptide in a secondary challenge, wherein the pre-challenged T cells are obtainable by exposing the T cells to the protein; and measuring the reactivity of the pre-challenged T cells with the peptide in the secondary challenge of step iii), and the peptide is a cryptic peptide if T-cell reactivity is observable in the secondary challenge but not in the primary challenge.

Granted: 2008-04-15
Abstract: The present invention makes the slots of stator core 2A of stator 1A rectangular enclosed slots 4A in which triangular projecting parts 3a are formed on the inner periphery side of this stator core 2A. It cools stator core 2A by passing cooling gas through projecting parts 3a. It also causes the magnetic flux that reaches stator core 2A  from permanent magnets 6 by passing through retaining ring 8 and air gap 9 to pass the inner periphery sides of projecting parts 3a of stator core 2A. By this means, it prevents oscillation of magnetic flux density in the peripheral direction, reduces the eddy currents in retaining ring 8 which accompany this oscillation, and prevents temperature rise.

Title: Method and apparatus for using machine vision to detect relative locomotive position on parallel tracks
Inventor: KERNWEIN JEFFREY D
IPC: B61L25/02
Filed: 1999-05-31
Granted: 2001-12-25
Abstract: An automatic train control system, including a track occupancy detector is disclosed which utilizes an image sensor disposed on the front of a locomotive which scans an image immediately in front of the locomotive and is capable of detecting the presence of the occupied track and any parallel tracks disposed on either side of the occupied track. Image processing is accomplished using a Laplacian edge detection algorithm and a Hough transform line detection algorithm. An on-board computer determines the slope of lines corresponding to rails extending ahead of the locomotive. The lines are grouped into lines having positive and negative slope and the number of lines in each group is determined.      Based upon the number of lines having positive and negative slopes, a determination of occupancy is made. The information from the track occupancy detector is provided to other equipment located on the locomotive and used to assist with other advanced train control functions.

Title: Method for improving the wanted signal in a radio receiving unit
Inventor: ROTH SABINE
IPC: H04B1/06
Filed: 1999-06-30
Granted: 2010-06-01
Abstract: It is known for a signal-strength detection unit to be used to detect the ratio of the input signal to the wanted signal obtained after it. A disadvantage in this case is that interference elements, which are also amplified, not only corrupt the output signal of the signal-strength detection unit, but can also adversely affect the quality of the wanted signal. The invention is based on the object of providing a method for improving the wanted signal in the receiving unit of a communications system. The method according to the invention for improving the wanted signal in a radio receiving unit having a channel filter, having a switch, having a control unit, having a signal-strength detection unit and having controllable amplifiers is distinguished in that the control unit drives the switch in such a manner that the switch alternately supplies a first signal upstream of the channel filter and a second signal downstream from the channel filter to the signal-strength detection unit, and that the output signal of the signal-strength detection unit is supplied to the control unit, and that the amplifiers are driven as a function of the output signal.

Abstract: An overtop position is to be established in a hydrostatic type continuously variable transmission, and an increase of the maximum speed and the maintenance of power performance are to be made compatible with each other. In a hydrostatic type continuously variable transmission, the angle of inclination of a movable swash plate is controlled in such a manner that a target Ne is calculated from both RC (riding condition) and throttle valve opening, then the target Ne thus calculated is compared with an actual Ne to determine a rotational direction and DUTY of a control motor, and the operation of the control motor is controlled in accordance with the thus-determined data and angle information on the angle of the movable swash plate provided from an angle sensor. In a constant speed vehicular traveling, the change gear ratio is set at TOP ratio and a shift is made to OVERTOP when predetermined overtop control conditions ((1) the current change gear ratio should be at TOP position, (2) the degree opening of a throttle valve should exceed a threshold value determined according to a vehicular speed, and (3) the engine speed should exceed a preset value) are satisfied, thereby increasing the maximum vehicle speed.
