Title: Contour emphasizing circuit
Inventor: AIDA TORU
IPC: H04N5/21
Filed: 1998-07-24
Granted: 2005-05-17
Abstract: A contour emphasizing circuit which comprises a contour pick-up unit 10 for picking up a contour component HE from an input luminance signal Y, a level judging unit 15 for judging the luminance level of the input luminance signal Y, a coefficient control unit 17 for changing the coefficient in a plurality of steps depending upon a judgement signal and multiplying the contour component HE by the coefficient to output the product, and an adder 14 for adding the contour component outputted from the coefficient control unit 17 to the input luminance signal Y to output an emphasized-contour luminance signal. The coefficient to be multiplied by the contour component HE is changed in a plurality of steps depending upon the luminance level of the input luminance signal Y, and the contour component HE to be added to the input luminance signal Y is controlled to have a magnitude appropriate to the luminance level of the input luminance signal Y. As a result, the contour is emphasized according to the luminance level of the input luminance signal Y  without causing excessive contour emphasis by adding a large contour component to a dark image of a small luminance level, thus preventing formation of unnatural images.

Title: Method for automatically adjusting the aeration of an installation for biological treatment of waste water
Inventor: AUDIC JEAN-MARC
IPC: C02F3/00
Filed: 1998-06-15
Granted: 2007-05-08
Abstract: The oxidoreduction potential is measured on each of a number of tanks. A data processing system analyzes the oxidoreduction potential evolution and establishes a diagnosis of the aeration/biology couple to ensure the degradation reactions of the carbonaceous and nitrogenous pollution. It is then determined whether to start, to continue, or to stop aeration in the tanks, depending on the required degree of purification. In the first tanks, priority is given to the treatment of carbonaceous pollution with specific parameter representation of the oxidoreduction potential threshold values. In the last tank, fine-tuning the treatment of the carbonaceous and nitrogenous pollution is accomplished by managing the aeration.

Abstract: An anti-rotation clip is adapted to be attached to a fastener or connector assembly to ensure the tightened threaded connection of the assembly. The anti-rotation clip in one embodiment of the invention includes one or more co-axial clips to radially and forcibly grip one or more hexagonal parts rotatable to a body, and a pair of tang members extending from one clip to engage a pair of grooves having flat bottoms on the body to prevent the hexagonal parts from rotation and the clip from axially moving away relative to the body. In another embodiment of the invention, two co-axially connected clips are adapted to radially and forcibly grip two connectors, having hexagonal exteriors, which are in a tightly threaded connection to a body and may be loosened in opposite rotary directions. The two clips lock the two connectors together to prevent the loosening of either one. An axially spaced apart tang member restrains a flange member on the body to prevent the clip from displacement from its axial position. The anti-rotation clip is simple in structure, easy for use and no plastic deformation is required during installation so that stress concentration is avoided which is especially good for aerospace applications.

Abstract: A method is provided for forming an autologous graft by distending a donor blood vessel, and harvesting the distended portion of the vessel. Also provided is a device for in vivo, or in vitro vessel distension. Typically t he devise is implanted, for example, using endoscopic techniques, in a patient sometime prior to another surgery on that patient, which includes implanting a vascular graft. The device includes a stretching mechanism which is attached to a donor blood vessel, means for operating the stretching mechanism to cause the vessel to distend, and a controller, preferably externally located , for controlling the operating means. In a preferred embodiment, the device includes a pair of opposed straps (10, 12) attached to a healthy, small diameter donor blood vessel such as a femoral artery in the leg. The straps (10, 12) are displaced from each other over a period of time to continuously distend or elongate the donor vessel. The distended portion of the donor vessel is excised at the time of the bypass surgery. The ends of the donor vessel are then sutured end to end to repair the donor vessel, a procedure common in vascular repair, and generally accomplished without complication. The result is a totally autologous, living vascular graft.

Abstract: A method and system for continuously treating ship ballast water enroute to reduce or eliminate harmful microorganisms therefrom, before discharge of the ballast water into coastal waters. During the ships voyage, and before the ballast water is discharged, the ballast water is continually passed through an interconnected UV sterilization system for treatment by ultraviolet radiation. One or more dispensing pumps are provided to transport the ballast water through the length of the UV system, which includes one or more UV units to process and sterilize the ballast water. In cases where large volumes of water need to be processed or where individual ship design is limiting, secondary piping to divert the flow of ballast water from the main piping system through placement of diverter valves, may be added to incorporate additional UV units or pumps. Flow jets secured to the inside of a ballast tank or hold may also be used to ensure proper circulation and mixing of the ballast water to be treated.

Abstract: A digital signal processor DSP for bit-reversal of a large data array of a size has a direct memory access (DMA) controller for performing in-place bit reversal routines on an external memory during a first stage, and a central processing unit (CPU) for swapping small sub-arrays on internal memory in a second stage. The two stage method according to the invention importantly reduces the real-time implementation for sorting large size data arrays on uni-processor DSP platforms, by extensively using the external memory and avoiding a random access to the internal memory. As well, the invention provides for improved dense integration and reduced costs when used in dense wavelength division multiplexing (DWDM) systems.

Granted: 2003-02-11
Abstract: An air filter element having end caps molded of foam material, and in which one of the foam end caps also employs the foam material as a radial seal gasket. Tubular inner and outer liners support a tubular filter element. The first ends are molded in a closed urethane end cap sealing one end of the filter element. The other end is molded to provide an open end cap in the form of an annular ring which encases the filter element and the liners, and provides a radial seal gasket. A  substantially rigid plastic ring has a base embedded in the open end cap annular ring, and an upstanding flange which carries the radial seal gasket. The ring closely fits within the inner liner, and the fit between the inner liner and ring provides a fluid restriction such that when the foamed urethane material forms on the annular flange, it carries up one side of the upstanding flange to form the ring, but is restrained from passing to the other side to leave an isolating gap between the other surface of the flange and the inner liner.
