Title: Method for detecting poor meat quality in groups of live animals
Inventor: TONG ALAN KWAI-WAH
IPC: A01K29/00
Filed: 1996-10-16
Granted: 2004-10-05
Abstract: The invention provides methods of detecting poor meat quality in live animal s using infrared thermography. Animals from a group of live domestic animals such as cattle or swine are scanned to produce thermographic images. The images are then statistically analyzed to determine a measure of central tendency such as the mean temperature for each animal's image and for all of the images in the group. A measure of dispersion from the measure of central tendency, such as standa rd deviation is determined. Then, animals are rejected as having a high probability of producing poor meat quality if the measure of central tendency for that animal's temperature differs from the measure of central tendency for the group by more than 0.9 standard deviations. Alternatively a set percent of animals are rejected, preferably up to 20 %, these being animals whose measures of central tendenc y differ the most from the measure of central tendency for the group. When mean temperature is used as a measure of central tendency, t he method is preferably practised by rejecting animals whose mean temperature differs from the group mean temperature by more than 1.28 times the standard deviation for the group. The method is particularly useful in detecting high probability of poor meat quality in groups of animals in an antemortem environment which have mean temperatures significantly above or below the normal surface temperatures fo r unstressed animals.

Abstract: A an optical fiber array block comprising an optical fiber array having optical fibers, a predetermined length of the coating of each optical fiber being removed, a basic block on which the optical fiber array is mounted, an optical fiber fixing block for fixing the coating-removed portion of the optical fiber array, and epoxy for fixing the coating-removed optical fiber array disposed in a connecting portion of the basic block, wherein the basic block comprises a front portion coupled to input/output optical waveguides of an optical waveguide device and having a groove in which the coating-removed optical fibers are disposed, a rear portion having a groove in which coated optical fibers are disposed, and a connecting portion for connecting the front portion and the rear portion, having a tapered structure so that its width changes in the range from the width of the front portion to that of the rear portion, and in which the coating-removed optical fibers aredisposed. Therefore, the length of a bent optical waveguide area necessary for obtaining the distance of input/output waveguides in a chip of an optical waveguide device can be reduced by reducing the distance between optical fibers by half, that is, from 250 µm to 125 µm, thereby greatly reducing the size of the optical waveguide device.

Title: Device for the protection of objects or body parts against vibrations
Inventor: KARALL GERHARD
IPC: A41D13/00
Filed: 1999-07-21
Granted: 2005-03-15
Abstract: There is disclosed a device for the protection of objects or body parts against vibrations, in particular a vibration-damping glove or antivibration glove, including at least one vibration-damping  layer. In order to realize such a device, which causes noticeable damping of vibrations even in the low-frequency range of vibrations (31.5 to 200 Hz) and, in addition, remains maneuverable to the largest extent possible, at least one vibration-damping layer, on its surface facing away from the object or body part to be protected, includes indents for decoupling movements in at least one direction in the plane of that surface.  The indents, on the one hand, cause the vibrations oriented in the plane of the surface to be deflected into the interior of the layer, thereby enhancing the vibration-damping effect, in particular in the low-frequency range. On the other hand, a high degree of movability of the vibration-damping layer, and hence of the overall device, is ensured by the indents.

Granted: 2004-06-22
Abstract: In an Internet facsimile apparatus, a mail header receiving section receives a list n-th mail header portion of e-mail. Next, a header analyzing section analyzes the mail header portion and checks whether or not the e-mail is fragments of the e-mail obtained by dividing the e-mail. A table generating section registers the fragments in processing into a table. Thereafter, the fetching determination; section checks whether or not the all fragments having the same ID are prepared. If all fragments are prepared, a data receiving section reads the fragments from a mail server sequentially from the first. Text codes of attached files included in the fragments are binary converted sequentially so as to be stored in a buffer section. A printing determination section instructs a print processing section to execute printing when there is image data corresponding to one page of an original in the buffer. This makes it possible to receive a division mail at low cost in the Internet facsimile apparatus.

Title: N x m optical wavelength routing switch
Inventor: WU KUANG-YI
IPC: H04B10/29
Filed: 1998-04-07
Granted: 2002-01-15
Abstract: A switchable wavelength router switches wavelength division multiplexed (WDM ) optical signals between N input ports (101, 102) and M output ports (103, 10 4, 105). Each WDM signal is spatially decomposed into N pairs of orthogonally polarized beams by a polarization-dependent routing element, such as a birefringent element (201). A polarization rotator array (204) rotates the polarization of each beam pair so that both beams in each pair have the same  polarization. A wavelength filter (206) then demultiplexes each beam pair to  create N sets of four beams. A second polarization-dependent routing element  (202) spatially routes the four beams in each of the N sets based on their polarizations, and also spatially combines selected beam pairs from differen t sets to produce M pairs of beams. A second polarization rotator array (205) restores each beam pair to orthogonal polarization, and a final polarization - dependent routing element (203) recombines each beam pair to produce M outpu t beams at the output ports (103, 104, 105).
