Title: Color enhancement method
Inventor: CHRISTOFF JORDAN C
IPC: H04N9/73
Filed: 1999-11-12
Granted: 2006-01-10
Abstract: A color enhancement method for use in a video camera imaging system (10, 30) in the context of non-uniform lighting includes an adaptive algorithm (100- 110) for developing a shutter speed control signal, analog gain control signal and color balance signals from pixel luminance over one filed of video. The control signals developed during one field are used to control the camera (12) during the next field. The speed control signal and analog signal are determined based on the luminance signal obtained in digital form from the video camera, and analyzed over at least one field of video. During one field, the speed control signal and the analog gain signal target dark areas of the image and during the next field they target the bright areas of the image so that, over two fields, every pixel is within a workable range of luminance in at least one of two alternate fields.      As the color balance settings for the fields are adjusted according to the exposure settings and the luminance level, consistent hue values are maintained between alternate fields. Additionally, a pixel color detection circuit (18, 28) examines each pixel from the video camera (12) to determine whether it is in a color region of interest. The pixel color detection circuit uses a color offset signal, calculated by a controller (16, 60) based on the luminance signal during the preceding filed. The color offset signal indicates how far from neutral, or white, in the chosen color space, is the chrominance data from the camera.      The video camera and pixel color detection circuit may be sued to identify weeds or plant material on the ground. A controller (74) is responsive to the pixel color detection circuit and activates one or more spray nozzles (68, 70) when a weed is detected.

Abstract: A video camera includes an abutment piece which is perpendicularly placed on the anterior side of the bottom of a stand portion and abuts on an attachment body to which the video camera is to be attached, a lever portion which is rotatably attached on the posterior side of the bottom of the stand portion, and bias means for biasing the lever potion toward the bottom of the stand portion. The lever portion includes an abutment portion formed such that it abuts on the abutment body. The lever portion holds the attachment body between the abutment portion and the abutment piece when it is used, and is housed in the stand portion such that it is pressurized to abut on the stand portion when it is not used.      This structure enables the video camera to easily be attached to and detached from various attachment bodies such as flat display that are different from each other in thickness. When the video camera is detached from the body, the lever portion is compactly housed and accordingly the video camera can be placed directly on a flat surface for use.

Abstract: A mechanic's bench vise which is easy to use and increases the maximum level of clamping force on a workplace in a pair of jaws of the vise. Another benefit is that it allows a vise to be used performing operations such as installing bushings, die punching holes, and setting rivets. One feature of the invention is that it measures the amount of torque which is applied to the torque arm. The invention broadly comprises a vise having at least one long slender torque arm for opening and closing a pair of jaws of a vise and a ratchet for opening and closing a pair of jaws of the vise. In a first aspect of the invention, the torque arm is not intended to be removed from the vise during normal service.  In a second aspect, the length of the torque arm is adjustable. In a third aspect, the torque is removable for shipping and storage and to allow the use of different style and length torque arms. In a fourth aspect, the torque arm is calibrated to measure the clamping force on a workpiece which is clamped in the jaws.

Title: Threaded connection with high compressive rating
Inventor: COSTA DARRELL S
IPC: F16L15/06
Filed: 2000-04-28
Granted: 2009-06-09
Abstract: The surface areas available for absorbing compressive loading of a threaded connection (30) are increased by increasing the engaged area of a torque shoulder (35) in the connection (30) and by reducing the spacing between the stab flanks of the threads (33, 34). The areas are increased by increasing the dimensions of the components and by decreasing the machine tolerances permitted in manufacturing the components. The gap (x) in the connection adjacent the torque shoulder is reduced so that the contact surface area of the torque shoulder is increased while the close proximity of the surrounding cylindrical walls of the connection reduces voids that can receive plastic deformation of the torque shoulder comers. The surfaces adjacent the torque shoulder are cylindrical (37, 38) in shape rather than being tapered to reduce machining costs and increase the speed o f manufacture of the connection.
