IPC: H04N5/44
Filed: 1997-11-10
Abstract: Un premier découpeur de données fournit les résultats provisoires du décodage de symboles à niveaux multiples dans un récepteur de télévision numérique (DTV). Le brouillage dans le même canal accompagnant les symboles à niveaux multiples est supprimé au moyen d'un premier filtre en peigne afin de réduire l'énergie du brouillage dans le même canal avant le découpage des données dans un deuxième découpeur. Le premier filtre en peigne recode les symboles transmis au deuxième découpeur. Un deuxième filtre en peigne, utilisé comme postcodeur après le deuxième découpeur, recode le train de données rétabli par le deuxième découpeur afin de produire des résultats supplémentaires de décodage de symboles. Un circuit détecteur de brouillage dans le même canal détermine les niveaux d'énergie du brouillage dans le même canal associés aux résultats provisoires et supplémentaires du décodage de symboles. Les résultats provisoires du décodage de symboles sont utilisables comme résultats définitifs du décodage de symboles seulement si le détecteur de brouillage dans le même canal ne produit pas un message indiquant que le train de symboles reproduits dans le récepteur DTV est accompagné d'artefacts d'un signal de télévision analogique provoquant du brouillage dans le même canal, artefacts qui sont éliminables par le premier filtre en peigne et dont le niveau d'énergie est suffisant pour fausser irrémédiablement les données provenant du premier découpeur.

Title: Folding table leg apparatus
Inventor: GAYHART JON W
IPC: A47B3/00
Filed: 1998-04-22
Abstract: A folding table leg apparatus for a table including one or more legs operable between an extended and a folded position. The folding table leg apparatus associated with each of the legs includes a pair of side supports which are connected to the underside of the table top. Each of the side supports includes a receiving notch which receives a cross bar connected to the upper end of the table leg when the table leg is in the extended position. A hinge bracket and a folding plate are connected between the pair of side supports and the table leg to permit the table leg to move between the folded and extended position. The table leg is pivotable about a lower leg pivot axis which is spaced from the upper end of the table leg, such that when the table leg is in the folded position, the distance which the table leg extends from the folding apparatus is less than the entire length of the table leg.  The folding apparatus further includes a locking mechanism that secures the cross bar in the receiving notches when the table leg is in the extended position. The locking mechanism includes a pair of locking brackets joined by a connecting rod such that the locking brackets are operatively joined. As the folding table leg moves from the folded position to the extended position, the cross bar interacts with a cam surface on each of the locking brackets to rotate the locking brackets away from the receiving notches thereby allowing the cross bar to be received in the receiving notches formed in the side supports. A torsion spring holds the locking brackets in a locked position to securely hold the cross bar in the receiving notches when the table leg is in its extended position.

Abstract: An insulative magnetic layer is disposed between a power source conductor layer and a ground conductor layer of a printed-wiring board.  Two pieces of conductors are formed by cutting out a part of the power source conductor layer.  Another two pieces of conductors are formed by cutting out a part of the ground conductor layer.  The former conductors and the latter conductors are connected by five viaholes.  A spiral coil inductor of a spiral form is formed in this way.  This inductor has the strengthened inductance owing to the insulative magnetic layer provided therein.

Abstract: A light-and-shade inspecting apparatus and method therefor, includes an image pick-up device for picking up an image of the object to output an image data, an integrated image calculating portion for dividing the image data outputted from the image pick-up device into a mesh pattern of meshes and then adding together the image data within each of the divided meshes to obtain an integrated image, a differentiated image calculating portion for performing a difference operation between each pair of meshes separated by a predetermined interval from each other with respect to their corresponding two integrated images obtained through the integrated image calculating portion, a defect detecting portion for comparing a value obtained through the differentiated image calculating portion with a predetermined value to detect as a defect portion which is partially different in luminance from the other portions on the object, an average value calculating portion for calculating an average value of the integrated image obtained through the integrated image calculating portion, and a light-and-shade deciding portion for deciding whether the defect detected by the defect detecting portion includes a light defect or a shade defect based on the average value obtained through the average value calculating portion and values of the integrated images in respective pairs of meshes apart by the predetermined interval from each other which have been subjected to the difference operation. Thus, low contrast defects can be precisely detect by distinguishing light and shade defects from each other and without mistaking a single defect for two separate defects.
