Patent EP-0477536-A2 (EP)
Inventor: WERTZ RONALD D
IPC: G01N21/84
Filed: 1991-08-22
Abstract: An optical inspection system inspects individual sheets having scrolled and unscrolled edges for defects in a production line with high transfer velocities. Each of the individual sheets are delivered in a production line with some spacing between them and potentially with some degree of skewness and offset from the production center line. The inspection system of the present invention utilizes a formed viewing window over which individual sheets from the production line are delivered. As each sheet is delivered over the formed viewing window, the undersurface of each individual sheet is uniformly and continuously illuminated along the length of the formed viewing window with high intensity diffused light. The reflected light from the surface of each moving individual sheet is captured by at least one video camera. As the sheet moves across the formed viewing window, a line-by-line video image is captured and stored according to a rectangularization technique which eliminates the need for customized masks. An analyzer receives the stored information and analyzes the stored information for the presence of defects.

Abstract: An automatic document conveying apparatus and method for use with an image forming device such as a photocopying machine. The apparatus comprises a document feeder (5) for feeding documents into the apparatus, a document conveyor for conveying documents to a copying position on the photocopying machine, a document reconveyor section (6) for re-conveying documents back to the copying position and also for conveying documents out of the apparatus, and a controller (31) for controlling operation of the feeder (5), conveyor and reconveyor (6). The controller (31) controls the feeding motor (28) for driving the document feeder (5) and the conveying motor (29) for driving the document conveyor such that the feeding motor (28) is driven during operation while the conveying motor (29) is turned off and on. Hence, rush current travels to the conveying motor (29) during on/off operation and not to the feeding motor (28) during continuous on operation thus reducing the load imposed on the power supply and eliminating the need for a delay time between starting of the respective motors.

Abstract: The invention relates to a vehicle spare tire lift unit including a drive shaft (48) rotatably mounted in spaced walls (32, 34) of a housing. A spool (60) is rotatably mounted on the shaft (48) within the housing, and is coupled to the shaft via a reduction gear train and a torque-limiting clutch, so that multiple revolutions of the drive shaft are required to produce each revolution of the spool (60). A cable (80) for supporting a spare wheel and tire is anchored by its inner end in the base of a narrow annular track (76) in the spool (60). The track (76) has a width substantially the same as the diameter of the cable so that the cable wraps radially outwardly around itself in a spiral overlapping manner. 
     The spool comprises first and second plate members (62, 74) which define the narrow track (76) therebetween. The second plate member (74) is mounted on a hub (68) of the first plate member (62) and is fixed against rotation relative thereto. 
     The reduction gear includes a gear ring (96) having internal, i.e. inwardly directed gear teeth (98), formed integrally with the second plate member (74). Within the internally geared ring (96) is a gear (118) having external, i.e. outwardly directed gear teeth (119). The external gear (118) is formed integrally with a control plate (115) rotatably mounted on an eccentric or cam (120). The eccentric is rotatably mounted on the drive shaft (48), and is rotatably driven by the drive shaft via the torque-limiting clutch (125). The external gear (118) orbits within the internally geared ring (96), but is prevented from rotating, upon rotation of the drive shaft and eccentric, to produce the reduced-ratio rotation of the ring (968), and therefore of the spool.

Abstract: An efficient digital beam-forming network (100) utilizing a relatively few small-scale A/D converters is disclosed herein. The inventive beam-forming network (100) is disposed to generate an output beam B in response to a set of N input signals. The set of input signals is provided by an antenna array (110) having N elements, upon which is incident an electromagnetic wavefront of a first carrier frequency. The present invention includes an orthogonal encoder circuit (170) for generating a set of N orthogonal voltage waveforms. A set of biphase modulators (162-168) modulates the phase of each of the input signals in response to one of the orthogonal voltage waveforms, thereby generating a set of N phase modulated input signals. The N phase modulated input signals are combined within an adder (180) to form a composite input signal. The inventive network (100) further includes a downconverting mixer (184) for generating an IF input signal in response to the composite input signal. The IF input signal is then separated into baseband in-phase and quadrature-phase components by an I/Q split network 192. A pair of A/D converters (198, 200) then sample the in-phase and quadrature-phase components of the input signal. A decoder (202), coupled to the orthogonal encoder circuit (170), provides decoded digital in-phase signals and decoded digital quadrature phase signals in response to the digital in-phase and quadrature-phase signals. The present invention further includes a digital beam-former (130) for generating the output beam B by utilizing the decoded in-phase and quadrature-phase signals.

Abstract: An algorithm is provided for improved lateral force during cornering while in antilock braking mode. For each wheel, the peak slip value at which maximum adhesion between tyre and road occurs is determined, and the peak value is reduced by offsets (or factors) to increase lateral force according to the cornering manoeuvre in progress to derive a target slip value. A cornering offset and an evasive offset are functions of steering wheel angle and steering wheel rotation rate, respectively, and of vehicle deceleration. When slip is determined using average vehicle speed, a geometry correction term which is a function of steering angle, vehicle speed and deceleration is added to the target value. The offsets and the correction term have different values for inside and outside wheels.

Abstract: An optical fiber for amplifying or sourcing a light signal in a single transverse mode. The fiber comprises a host glass doped with erbium (Er) and a sensitizer such as ytterbium (Yb) or iron (Fe). Preferably the host glass is doped silicic glass (e.g., phosphate or borate doped). Electrical energy is provided to diode lasers that pump the Nd laser rod, which in turn pumps the fiber. Such a configuration for pumping the fiber provides a high energy transfer from the diodes to the Nd laser rod, which in turn enables high pumping powers to be coupled into the single-mode co-doped fiber. Based on the amplification characteristics of the co-doped fiber and the efficient coupling of power from the laser diodes, the amplifier provides power and small signal gains comparable to the best observed, while requiring only conventional and readily available diode-based pump sources.
