Abstract: An apparatus can include a number of memory devices and a memory controller coupled to one or more of the number of memory devices. The memory controller can include a row hammer detector. The memory controller can be configured increment for a first time period a row counter in a first data structure and a refresh counter. The memory controller can be configured to increment for a second time period a row counter in a second data structure and the refresh counter. The memory controller can be configured to determine that a value of the refresh counter exceeds a refresh threshold and responsive to the determination that the value of the refresh counter exceeds the refresh threshold, issue a notification.

Abstract: A system and method for disinfecting hard surfaces in an area such as a hospital room including a light source emitting UV light and a reflector mounted behind the light source for concentrating and directing the light toward a target. The light source and reflector rotate to direct the concentrated beam around a room, thereby making more efficient use of the energy being emitted.

Abstract: A device and method of cleaning a space and, in particular, successive rows of objects using light energy such as UV-C. The device includes an articulated boom that is adjustable along four degrees of freedom to optimize an orientation of the boom relative to the rows of objects.

Abstract: A flat and detachable electrical connection system between a flat lighting module and a lampholder is described. The flat lighting module comprises a lighting panel, control circuitry for controlling the lighting panel, and electrical contact pads connected to the control circuitry, all supported at least in part by a mechanical support plate; the mechanical support plate being at least partially enclosed in a housing with a provision or opening so that light can be emitted from the lighting panel; and where the mechanical support plate includes a male mechanical support connector section that extends out from the mechanical support plate in the same plane as the thickness of the lighting module; and where the male mechanical support connector section includes means for non-permanent locking or latching of the lighting module to the lampholder.

Abstract: Heat sinks having a mounting surface with a coefficient of thermal expansion matching that of silicon are disclosed. Heat pipes having layered composite or integral composite low coefficient of expansion heat sinks are disclosed that can be mounted directly to silicon semiconductor devices.

Abstract: A body support structure includes a base and a cushion moveable between a seating configuration and a sleeping configuration. The cushion may include foldable first and second sections. In one embodiment, a spacer includes first and second support surfaces, and is pivotal between an upright position, wherein the first support surface engages and supports the cushion in the seating configuration, and a down position, wherein the second support surface engages and supports the cushion in the sleeping configuration. Methods of reconfiguring a body support structure are also provided.

Abstract: An esophageal deflection device includes an elongate outer tube that has a natural curved deflection at a position that corresponds to a targeted esophagus region for deflection. The outer diameter of the outer tube is substantially matched to an inner diameter of the esophagus to closely contact the esophagus wall, or is at least half of the inner diameter, or is smaller and includes suction ports for drawing the esophagus wall inward. An insertion rod or tube includes a portion that is stiffer than the curved deflection, and slides into the elongate outer tube to straighten the tube and can serve to guide the deflection device into an esophagus. Subsequent withdrawal of the insertion tube or rod will allow the curved deflection to return to its natural shape and deflect the targeted region of the esophagus. A three-dimensional array of temperature sensors can be disposed near an outer surface of the elongate outer tube.

Abstract: The invention provides an economical laser welding method for joining two metal materials with a fillet joint. The method reliably compensates for tolerances between the two materials and can be used in various light conditions and production environments. In addition, the method does not require additional equipment for purposes of seam tracking. Instead, the method includes oscillating a laser beam, for example in a “figure 8” pattern, while moving the laser beam laterally along an interface between the two materials. The width of the fillet joint is increased compared to the fillet joint that would be formed using a non-oscillating laser beam, and thus compensates for the tolerances. The width of the fillet joint depends on the oscillation amplitude of the laser beam, rather than the beam size.
