Patent number: 12247889Abstract: A temperature sensor includes a platinum member having a base portion and a plurality of prongs extending from the base portion. The platinum member is positioned within a housing that includes a first platform having a first support surface supporting the base portion, and a second platform having a second support surface spaced apart from the first support surface. The second support surface supports an end portion of at least one prong of the plurality of prongs, and medial portions of the plurality of prongs between the first and second support surfaces are suspended at a distance from an interior surface of the housing. In some cases, the housing further includes one or more support members between the first and second platforms that project from the interior surface of the housing toward the medial portion of one or more prongs to limit an amount of bending of the prongs.Type: GrantFiled: November 6, 2023Date of Patent: March 11, 2025Assignee: Fluke CorporationInventors: Timothy B. Brown, Rong Ding, Donald D. Leach, David W. Farley

Patent number: 9671007Abstract: Low-noise pulleys and methods of constructing low-noise pulleys are disclosed. In a first aspect, first and second pluralities of arms extending radially outward from the outer hub to the outer rim are angularly offset from each other about the axis of rotation to eliminate symmetry across the lateral midline of the pulley. In a second aspect, the radially outermost ends of a plurality of arms are arcuately spaced apart according to a pitch sequence describing a pseudo-random pattern of relative spacings so as to reduce or eliminate rotational symmetry of the pulley. In a third aspect, features of the first and second aspects are combined, and in one embodiment, first and second pluralities of arms are, respectively, approximately oppositely canted so as to vary the arcuate spacings of the laterally outermost ends of the arms.Type: GrantFiled: December 23, 2013Date of Patent: June 6, 2017Assignee: DAYCO IP HOLDINGS, LLCInventors: Kevin G. Dutil, James Kevin Lindstrom, Zachary Fittro, Jeffrey A. Swane, Donald B. Brown, Robert James Crist

Patent number: 4300715Abstract: An assembly system for assembling microcomponents of semi-conductor or other electronic devices includes on a unitary machine frame the tooling for precision excising tape mounted microcomponents, precision forming their electrical leads, placement of the components in correct registration with conductors on a pre-positioned substrate, and bonding the formed leads to the conductors. Bonding is conducted by clamping the leads to the conductors at the bond site, moving a heated anvil into contact with a heat conductive path to the bond site and withdrawing the heated anvil while maintaining the clamping.Type: GrantFiled: January 18, 1980Date of Patent: November 17, 1981Assignee: The Jade CorporationInventors: Alan S. Keizer, Donald B. Brown
