Title: Biological specimen collection system
Inventor: DAYKIN VICTOR
IPC: A61J1/00
Filed: 1993-04-19
Abstract: The present invention provides for a biological specimen collecting system for holding a biological specimen in a long term sustained sealed environment. The biological specimen collecting system includes a container for holding the biological specimen and a sealing closure cap. The container is of circular section and has generally vertical sidewalls, the sidewalls at the top terminating in an inwardly sloping sealing surface. The container has a first thread on an exterior surface thereof, the first thread being located below the sealing surface. The sealing closure cap has a peripheral groove to receive the container rim, the peripheral groove being defined by inner and outer walls and a top. The outer wall of the groove is provided with a second thread complementary to the first thread on the container for engagement therewith. The inner wall of the groove is provided with a sealing bead positioned above the second thread, the sealing bead contacting the sealing surface of the container to provide long term sustained sealing of the container by the sealing cap.

Inventor: FEIG EPHRAIM
IPC: G06T1/00

Abstract: The present invention improves either the processing speed or circuit complexity (or both) of a digital image processor by eliminating the conventional multiplication operation from the RGB to YUV and YUV to RGB transforms having NTSC compatible equation coefficients. In particular, the change of color-basis matrix for converting RGB data to obtain YUV data is factored into a scale factor and a coefficient matrix. The coefficient matrixcontains coefficients such that its product with the RGB input vector can be performed using only seven binary additions and five shirt operations. This process effectively removes the conventional multiplication operations from the RGB to YUV conversion. The scale factor is conveniently absorbed into the quantization of the YUV data before transmission. The quantization process includes a multiplication already and the two multiplication steps are folded into one step. Therefore, the absorption of the scale factor into the quantization step does not increase the processing time because no multiplication steps are added. This process of factoring the transform matrix is also applied to the inverse transform process. In the inverse transform process the change of color-basis matrix for converting YUV data to RGB data is such that its implementation reduced to five addition steps and two shift steps, again effectively eliminating the conventional multiplication operations. Also, the diagonal matrix is absorbed into the descaling process so that no multiplication steps are added to the inverse transform process.

Abstract: The invention provides an improved planer which effectively prevents undesirable torn grain.  The planer of the invention includes at least one planer knife or blade and at least one pressing member, both attached to and supported on a cutterhead.  The pressing member includes a head element which is located to have a predetermined angle with respect to the blade and is resiliently movable in a predetermined direction to press an edge of the head element against a certain position of a wood surface immediately before a cutting edge of the blade moving in a fixed direction for cutting or against a boundary between the wood surface and a chip being currently cut from the wood surface.          The direct pressing of the pressing member against the wood surface prevents rise of wood fibers and thereby effectively reduces or eliminates undesirable torn or chipped grain.
