Abstract: A multi-pattern reflector antenna for generating first and second antenna patterns from first and second RF signals having first and second frequencies of operation respectively. The antenna includes a reflector having a focal point, first and second subreflectors configured to image the focal point at first and second preselected locations respectively; and, first and second feeds positioned at the first and second preselected locations. The first and second feeds are configured to operate at the first and second frequencies of operation respectively and are operative to generate first and second radiated RF signals from the first and second RF signals respectively. The first and second subreflectors partially overlap each other with the first subreflector configured to be a frequency selective structure which reflects RF signals having the first frequency of operation and passes RF signals having the second frequency of operation. The second subreflector is configured to reflect RF signals having the second frequency of operation and pass RF signals having the first frequency of operation.

Granted: 2007-06-05
Abstract: A belt tensioner for a motor vehicle engine comprises a pivot shaft (28) and an eccentric pivoted structure (50) mounted for pivoted movement on the pivot shaft. The belt tensioner has a rotatable pulley member (90) mounted for rotation on the eccentric pivoted structure.  A spring (64) is constructed and arranged to bias the eccentric pivoted structure in a direction tending to force the rotatable pulley member into tensioning engagement with a belt (16) trained about the pulley member. A  mounting bolt (14) is constructed and arranged to mount the belt tensioner on the motor vehicle engine (12), said pivot shaft being movable relative to said mounting bolt and towards said belt during a belt tensioner installation procedure. The present invention also relates to a method of installing a belt tensioner in which the pivot shaft moves in a substantially exactly linear fashion as the tensioner is moved into tensioning engagement with the belt. In a preferred embodiment, when the belt tensioner is moved into tensioning engagement with the belt, an external force is applied to the tensioner to balance any belt load forces tending to tilt the tensioner during installation. The present invention also discloses a tensioner that has contact portions that oppose the tilting force applied by the belt during installation, and a portion that extends beyond the contact portions to facilitate installation.

Granted: 2011-05-31
Abstract: The invention relates to a method for evaluating the quality of a signal transmission path (2) presenting non-linear distortions. According to said method a specified test signal is sent from a transmitter (1) to a receiver (3). First the level of the received signal is adjusted in the receiver (3) and then a global quality evaluation is carried out using a specified comparative method. To adjust the signal level a local quality evaluation (11) based on the specified comparative method is carried out in a specified number of different, predefined windows (V1, à, VN-1, VN). Thereafter at least one window with an adequate local transmission quality is determined. The ratio of signal level of the test signal to signal level of the received signal is calculated in at least one window and the level of the entire received signal is adjusted on the basis of this ratio. Preferably only windows containing, for example, at least 50 % of the total signal energy are used for adjusting the level. The quality evaluation can be carried out using a known method such as the BSD method.

Title: A flow-through nmr probe having a replaceable nmr flow tube
Inventor: HANER RONALD L
IPC: G01N24/08
Filed: 2000-07-12
Granted: 2007-11-20
Abstract: A flow-through NMR probe having an NMR flow tube that is easily inserted or removed is provided. The NMR flow tube is positioned through a lower and upper insulator in a flow-through NMR probe by the use of a guide tube with a smoothly tapered inner surface. The guide tube leads from the base of the probe to the lower insulator. The NMR flow tube with attached inlet tubing is inserted into the probe through the guide tube and aligned along the central axis of the probe. The flow tube is aligned using upper and lower insulator rings positioned in the upper and lower insulators. Once the NMR flow tube is in place, the outlet end of the flow tube is connected to an outflow tubing with a detachable connector. The lower end of the connector is then seated in a key in the upper insulator ring to position the flow tube for spectral measurements. The invention is useful for applications that couple high performance liquid chromatography (HPLC) with nuclear magnetic resonance spectroscopy (NMR).

Title: Synchronization system for motors
Inventor: STRONCZEK STEVEN J
IPC: B60S1/08
Filed: 1999-12-29
Granted: 2008-09-23
Abstract: A synchronization system according to the present invention includes a signal generator that provides a "RUN" signal of a predetermined duration simultaneously to two or more windshield wiper motors in response to receipt of position signals generated by the motors. Each motor generates a position signal when the windshield wiper controlled by the motor is at a predetermined position. A gate circuit monitors the output of each motor to determine whether the motor is in the predetermined position. The gate circuit provides a trigger signal to the signal generator of the present invention only when each motor outputs a position signal. The trigger signal causes the signal generator to produce a subsequent "RUN" signal initiating another wipe cycle. Accordingly, the motors begin each cycle in unison.

Title: Pickup truck bed extender apparatus
Inventor: KMITA GERARD J
IPC: B62D33/00
Filed: 2001-10-29
Granted: 2007-03-27
Abstract: A bed extender apparatus adapted for use with a pickup truck bed to functionally enlarge the useable cargo area within the truck bed when a tailgate is in a lowered position. The bed extender includes a center wall which is pivotably mounted to an inner surface of the tailgate, and which can be pivoted into an upright position once the tailgate is moved into a lowered position. A pair of end walls are pivotably secured to opposite ends of the center wall. Each end wall can be pivoted out to a position extending perpendicular to the center wall once the center wall is in its raised or operative position. Each of the end walls can then be secured to an associated one of the vertical walls of the pickup truck bed. A principal advantage of the bed extender is that the end walls and center wall each include a plurality of members which, when the end walls are folded against the center wall, form an extremely compact arrangement which takes up virtually no appreciable cargo space within the pickup truck bed. The bed extender also forms an extremely aerodynamically efficient structure when in use.

Abstract: A thermal compensating apparatus (52) and method for maintaining a substantially constant fluid pressure within a subterranean well tool of the type that includes a bladder that is selectively expandable upon the introduction of pressurized actuation fluid for actuating said tool at a location in a well. A multi-stage piston (80, 84, 86) is movable in a housing. The piston includes a first surface (80') in contact with the actuating fluid and a plurality of second surfaces (80", 84", 86") in contact with well fluid surrounding the apparatus. The combined surface areas of the second surfaces are greater than the surface area of the first surface, so that expansion or contraction changes in the volume of the actuating fluid caused by temperature changes in the vicinity of the tool will result in movement of the piston for maintaining the actuating fluid at a relatively constant pressure.
