Abstract: A flushometer including a sanitation unit is described herein. The sanitation unit may be configured to emit ultraviolet light in response to the flushometer effectuating a flush of the fixture. The ultraviolet light may sterilize and/or sanitize a plume caused as a result of the flush. The ultraviolet light may be emitted for a predetermined amount of time to sterilize, sanitize, and/or kill any pathogens contained in the plume. Additionally or alternatively, the sanitation unit may emit the ultraviolet light periodically. For example, the sanitation unit may emit the ultraviolet light in response to receiving one or more signals from a gateway and/or server. The sanitation unit may provide an environmentally friendly solution that reduces water consumption and/or cleans, sanitizes, and/or sterilizes plumbing fixtures, toilet seats, etc. between uses without the need for harsh chemicals and/or cleaning solutions.

Abstract: A panoramic optical device includes a quadric reflector, a mirror, and a set of one or more optical elements. The quadric reflector has a conical shape, which tapers from a wide base to an apex. The apex includes an aperture. The mirror is positioned within the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror reflects environmental light that is reflected by the quadric reflector into the aperture or reflecting light emitting from the aperture onto the quadric reflector. The set of one or more optical elements are positioned at least partially within a volumetric region of the quadric reflector. The one or more optical elements focus light passing through the aperture.

Abstract: A degradation pick of the type used in such fields as road milling, mining, and trenching to engage and degrade tough materials such as asphalt, concrete, and rock may comprise a body attached at one end to a substantially cylindrical shaft. A hardened tip may also be attached to the body opposite the shaft. The hardened tip may comprise an axis offset from a central axis of the shaft. Such a degradation pick may be secured to an exterior of a rotatable drum or continuous chain so as to be repeatedly brought into contact with a surface of a material to be degraded. The body may comprise a protruding spine adjacent the hardened tip and opposite a direction of travel of the hardened tip when transported by a rotating drum or continuous chain.

Abstract: A reflector can have a conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror is location in a cavity and is positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the reflector into the aperture or reflect light emitting from the aperture onto the reflector. Stray light reflected by the mirror is absorbed by the cavity walls. A set of one or more optical elements can be positioned at least partially within a volumetric region of the reflector. The one or more optical elements focus light passing through the aperture to an image sensor.

Abstract: A quadric reflector can have an approximately conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror can be positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the quadric reflector into the aperture or reflect light emitting from the aperture onto the quadric reflector. The overhang enclosure can have a substantially conical shape which eliminates secondary reflection resulting from the environmental light reaching the aperture twice. Using the overhang enclosure to absorb the secondary reflection eliminates or minimizes banding.

Abstract: A magnetic display unit includes: a display layer; a magnetic layer located behind the display layer; and a quick-release mechanism including an activator, wherein the quick-release mechanism is adapted to increase the distance between the magnetic layer and the display layer such that, when activated by the activator, the quick-release mechanism causes any magnets located along the display layer to be released from the display layer.

Abstract: A degradation pick or holder shank for facilitating installation, retention and removal is disclosed. The shank may comprise an axially compressive portion that may contract radially when stretched axially and then expand again radially when released. An installation tool may be used to stretch the shank axially during insertion into a bore and then release the shank to retain it within the bore.

Abstract: A game includes a playing area including a grid arrangement of nine playing positions, each playing position including three concentric playing locations within the playing position, each playing location having an associated cylindrical receiving shape; and four sets of game pieces, each set of game pieces including three subsets of game pieces, each subset of game pieces including game pieces having a form corresponding to one of the playing location receiving shapes, including a solid cylinder having a first diameter, a hollow cylinder having a second diameter larger than the first diameter, and a hollow cylinder having a third diameter larger than the second diameter.

Abstract: An adapter may allow for non-rotating degradation tips to be secured to holders traditionally used for accepting rotatable bits. Such an adapter may comprise a body comprising an interface on one surface and a seat on an opposing surface. The interface may comprise a form complementary to an end of a holder and the seat may comprise a form for accepting a hardened tip.

Abstract: A method for removing contaminants from a natural gas feed stream from a well head is provided for. The natural gas feed stream is fed to a separation unit which contains a first gas membrane unit for removing hydrocarbons and a second gas membrane unit for removing carbon dioxide from the natural gas feed stream. The method allows the same unit to be used for either hydrocarbon conditioning of field gas for drilling operations (power generation) and/or for pipeline quality natural gas production from wells.

Abstract: A storage cabinet configured to accommodate electronic equipment is disclosed. The storage cabinet has front, rear, and side walls extending upwardly from a bottom to define a storage space. The storage cabinet also includes a compartment located within the storage space configured to accommodate electronic equipment. The compartment includes an electronic cooling device for each piece of equipment, a ventilation system, and-one or more components for receiving and transmitting wireless signals into and out of the cabinet.

Abstract: In one aspect of the present invention, a pick assembly is configured that comprises a pick shank configured to be press fit directly within a bore of a block. The pick shank comprises an inside and outside surface. The pick comprises a pick head opposite the shank. The shank comprises at least one longitudinal recess extending towards the pick head along the shank from a distal end of the shank. The recess allows the shank to resiliently collapse upon insertion into the bore while maintaining a press fit between the bore and the shank.
