Abstract: In some examples, a tool for manufacturing parts includes a body formed using an additive manufacturing process, where the body includes a plurality of repeating structures, and where the plurality of repeating structures include a first subset of repeating structures each having a first physical property as specified by a digital representation of the tool used in the additive manufacturing process, and a second subset of repeating structures each having a different second physical property as specified by the digital representation of the tool used in the additive manufacturing process.

Abstract: A filter arrangement includes first and second media packs with a support core in between. The support core includes a first ring at one end and, optionally, second ring at an opposite end. In some arrangements, at least a first member and second member extend from the first ring while being engagement-free to each other. In some arrangements, no more than a first member extends from the first ring, while being engagement-free relative to itself.

Abstract: A decorative air vent apparatus can be used to cover air vent openings that supply heated or cooled air to a room from a central HVAC system. The decorative air vent is comprised of a housing, a decorative insert, and a decorative face plate. The housing supplants or is inserted into a conventional HVAC air vent opening and provides a space for the attachment and display of a decorative insert on the interior of the vent opening. The decorative face plate attaches to the housing, and has a central opening allowing for visual observation of the interior of the housing for the observer's enjoyment of the displayed decorative insert. The insert and face plate present artistic patterns or depictions and are interchangeable. When not used in conjunction with the housing, the decorative insert can be attached directly to the decorative face plate and displayed on a flat surface.

Abstract: The present invention presents a method and apparatus for the dynamic combination of a heating element and an object presence sensor for the purpose of creating a control loop in which a heating element responds to the detection of any desired material within a measurable range from the heating element. The system described in the previous sentence will be referred to as “cell” for the remainder of this patent. One application of this invention is in cooktops that could dynamically create cooking regions from an array of these cells, allowing users to place pots or pans anywhere on the surface of the cooktop. The ability to create a dynamic grid which only heats up areas which are covered either directly by food or by an intermediate cooking vessel results in a state of the art cooking surface improving upon both the performance and efficiency of its predecessors.

Abstract: There is discloses an on-line method of analysing financial accounting data, a server and a computer program. Certain embodiments of the method comprise receiving at a server uploaded financial accounting data from a client computer which includes a set of accounts A organized into account groups G. The financial accounting data is mapped to an accounting ontology stored at the server comprising at least a pre-defined set of primary category tags C and a pre-defined set of base level tags B each associated with a primary category tag C. The accounts are mapped according to mapping account groups G to primary category tags C and mapping accounts A to base level tags B, wherein each base level tag B has an associated set of criteria K. The mapped data is then analysed at the server. The results may be authorized to be shared with interested third parties.

Abstract: The present invention discloses a method for the measurement of hydride using a chemiluminescent compound. The preferred chemiluminescent molecule is an acridinium compound. The source of hydride for the reduction of acridinium compound may be of chemical or biochemical origin, or the result of enzymatic catalysis. The chemical source of hydride, for example, might be metal hydrides, such as NaBH4. A biochemical source of hydride might be that derived from NADH, or NADPH, while an enzymatic source would be the class of oxidoreductases termed dehydrogenases which convert NADH or NADPH from NAD or NADP. There are numerous potential applications for acridinium compounds as chemiluminescent indicators of hydride. Any applied tests or diagnostic assays, in which hydride is either present at the onset of or generated through the course of a reaction, would benefit from the present invention.

Abstract: Improved nucleic acid probes capable of specifically hybridizing to rRNA of Listeria and not to rRNA of non-Listeria are described along with methods utilizing such probes for the detection of Listeria in food and other samples.

Abstract: A rhythm instrument utilizing improved sound producing element combinations for the bass, tom-tom and snare sections of an electronic drum to provide an advantageous audio reproduction of the sounds of conventional drums. Specifically, the improved sounding elements provide more accurate snap, staccato, roll, and rim sounds. In overall concept, the audio producing mechanisms include dynamic impact between an extended vibrationally displaceble element secured on opposing ends thereof to a base surface and a resilient band stretched across an upper surface of the vibrational element. Sounds are produced by causing a striker arm having a hard tip portion member to impinge upon the resilient band causing it in turn to strike the displaceable element. A bass sound is provided by a single such unit utlizing a wide metal strip as the displaceable element.
