Abstract: A collapsible wingback chair that includes a seat base portion and to which is secured a lower portion of a pair of side wings that include upper portions that are movable relative to a chair back that is pivotally mounted so as to be movable between an upright position when the chair is in use to a folded position in overlaying relationship with the base with the upper portions of the side wings also being folded relative to the base to thereby form a compact configuration for handling, shipping and storage. The side wings are selectively secured to the chair back when the back is in a raised position to thereby permit use of the chair in a conventional manner.

Abstract: A rotor assembly for centrifuging reaction vessels containing reaction mixtures in a device for asymmetric heating and cooling of reaction mixtures during centrifugation. The rotor contains at least one fan blade used to force ambient gas to pass the reaction mixture. Also provided is a device for asymmetric heating and cooling of reaction mixtures during centrifugation.

Abstract: A method and circuit is provided for detecting and correcting errors in an array of content addressable memory (CAM) cells. The array includes wordlines, searchlines, bitlines, and matchlines for reading from, writing to, and searching CAM cells in the array.

Abstract: A SCARA robot has a robot console, a first robot arm articulated on the robot console and swivelable about a first swivel axis, a second swivel arm articulated on the first swivel arm and swivelable around the second swivel axis extending substantially parallel to the first swivel axis, at least one work unit, at least one first swivel motor for swiveling an arm unit composed of the first and second robot arms relative to the robot console, at least one second swivel motor for turning the second robot arm relative to the first robot arm, and at least one work motor for actuating the work unit, with the motors being controllable by a power electronics, with electrical circuits including convertor circuits for current supply of the motors and at least one control circuit for operating the convertor circuits and thereby for controlling the motors, and with at least one rectifier circuit being received in at least one robot arm.

Abstract: Automotive audio systems that use directional planar magnetic transducers in a layout or placement configuration to provide direct or reflected audio imaging in stereo or surround sounds for individual passengers of an automotive vehicle with reduced crossed audio interference.

Abstract: A rigging system for angularly adjusting the output portions of a plurality of loudspeaker cabinets wherein each of the cabinets includes a pair of rotatably adjustable rigging disks which protrude outwardly thereof which are selectively receivable within an adjacent cabinet. Each cabinet has a first locking element for securing the disks therein with respect thereto and second locking element or elements for selectively securing protruding portions of disks of an adjacent cabinet whereby an angle of the output portions of each cabinet may be adjusted from substantially a planar orientation to a curved orientation to thereby change the overall wavefront characteristics of sound issuing from a vertical array of attached loudspeaker cabinets.

Abstract: The invention relates to a mechanism comprising at least one spring (3) for compensating the weight of a closing screen, said spring (3) being fixed, at one of its ends (32), to a ring (6) which is rotatably arranged around a shaft (4) having a circular cross-section. A stop spring (7) which is arranged around the shaft (4) ensures a one-way coupling between the ring (6) and the shaft (4), means (8) being provided for controlling the centripetal effort exerted on said shaft (4) by the stop spring (7).

Abstract: A heald frame including two posts, two cross members and connectors which are used for securing at least one post to at least one corresponding cross member. Each connector includes an intermediate tubular fixing element which is disposed in a housing provided in the cross member and indented with respect to a front face of the cross member and which element defines an internal volume in which a protrusion extending from the at least one post is seated.

Abstract: The present invention relates to a method and apparatus for detecting analytes in a medium, and more particularly the present invention relates to an assay based on light diffraction which appears or changes upon the binding of analytes to their specific receptors laid out in patterns on a substrate, which has high sensitivity due to the appropriate choice of such patterns. The present invention is based on the principle that the pattern of recognition elements, which gives rise to the diffraction of the incident light in a diffraction-based assay, can be chosen in such a way so as to facilitate detection, and to enhance the signal to be detected compared to known gratings such as parallel straight lines. In one aspect the substrate itself has a surface topography designed to enhance the diffraction pattern signals. In another aspect the substrate is a diffractive optic element having the analyte-specific receptors affixed to the optic element.
