Abstract: Apparatus and associated methods relate to dynamically monitoring radiation exposure of sensitive objects. In an illustrative example, a dynamic hazard visualization system may provide real time radiation exposure monitoring for medical personnel in an operation room. A dynamic hazard visualization system (e.g., DHVS), for example, may include a data store comprising a plurality of predetermined radiation intensity models. For example, the DHVS may receive at least one image received from a camera installed in the operation room. Based on the received image and one or more predetermined radiation intensity models, the DHVS may generate an inter-object properties data structure (e.g., IOPD) of the operation room. The DHVS may use the IOPS to generate, in real time, an instantaneous radiation intensity profile based on a dynamic geometry generated based on updated images received from the camera. Various embodiments may advantageously monitor radiation exposure of the medical personnel in real time.

Abstract: A flexible bus bar system for connecting printed circuit boards (PCBs), especially suited for high-power applications. The bus bar is constructed from multiple stacked thin sheets of conductive material, imparting flexibility and reducing mechanical stress on connected PCBs in applications prone to shock and/or vibration, such as electric vehicle power systems. The sheets may be laser-cut, optionally enabling formation of intricate geometries and/or integrated direct mounting apertures, potentially eliminating the need for additional connectors or crimps. One or more radiused curves are introduced into a central portion of the bus bar, holding the layers in alignment and providing flexibility and/or elasticity. The assembly may be reinforced with an adhesive-backed heat shrink. Methods of fabrication are also disclosed.

Abstract: Disclosed is a moisture reactive polyurethane hot melt adhesive composition that can be applied to substrates at a low coating weight even at application temperatures as low as 60 to 95° C. while retaining the advantageous high tack, green strength, cured bond strength and toughness of conventional high melting point polyurethane hot melt adhesives.

Abstract: Removable cab toe boxes are described herein to provide increased comfort to an operator while still allowing a cab to be rotated upwards to provide access to equipment below the cab. The removable toe boxes are removably affixed to the cab and, when installed, may provide at least a partial seal to prevent or reduce the amount of dirt or dust entering the cab. When the toe boxes are removed, equipment may move through the space created from the removal of the toe boxes to allow the cab to rotate.

Abstract: A semiconductor wafer processing system for processing a set of semiconductor wafers includes a bond treat station including an oven, a cleave station including a cleave assembly for cleaving the wafer, a transfer robot, and a controller for controlling the transfer robot. The controller is programmed to control the transfer robot to retrieve a first wafer of the set of semiconductor wafers from the bond treat station and control the transfer robot to deliver the first wafer to the cleave station for processing by the cleave assembly.

Abstract: A susceptor assembly for supporting a crucible during a crystal growth process includes a susceptor base, a tubular sidewall connected to the susceptor base, and a removable sacrifice ring interposed between the susceptor base and the sidewall. Each of the susceptor base and the sidewall is formed of a carbon-containing material. The susceptor base has an annular wall and a shoulder extending radially outward from an outer surface of the annular wall. The sidewall has a first end that receives the annular wall to connect the sidewall to the susceptor base. The sacrifice ring has a first surface that faces the outer surface of the annular wall, a second surface that faces an interior surface of the sidewall, and a ledge extending outward from the second surface that engages the first end of the sidewall.

Abstract: The present invention relates to a cooling plate for thermal management of a system such as an electronic. A unitary, single-material cooling plate can be formed from three stacked flat aluminum sheets, including a top sheet, a bottom sheet, and a middle sheet. An open channel is formed in the middle sheet by laser cutting, and enclosed by the top and bottom sheets. The top and bottom sheets are secured to the middle sheet through continuous laser welds applied around the circumference of the open channel and laser welding applied around the outer perimeter of the cooling plate. Flow modifiers or sensor assemblies may be encapsulated within the middle sheet open channel. The open channel may, in some embodiments, constitute a single open coolant chamber, with islands of material positioned therein and welded to the top and bottom sheets. Methods for manufacture of such cooling plates are also disclosed.
