Abstract: Pedal assemblies and methods provide for signal control, such as for controlling audio and/or effects path signals used in generating audio from a musical instrument. The pedal assemblies may provide for simultaneous audio and effects control via electrical pathways dedicated to each. Rotation of the pedal about one or more axes of rotation results in modifying an electrical characteristic of devices of the pedal that control the audio and effects path signals. A particular axis of rotation that modifies the electrical characteristic of a device may be configured to produce a particular audio or effects path control based on which of the jacks are in use such that by changing the jacks that are in use, the function of a particular axis of rotation may change. Furthermore, a pedal assembly may provide for two axes of rotation where the centers of rotation of the two axes are non-coincident. The two axes of rotation may be better isolated as a result.

Abstract: An arch support orthosis includes an arch curve being variably tensioned for supporting a user's arch and foot. The arch support orthosis includes a metatarsal curve, a curved heel portion and a continuous medial longitudinal arch curve. An anterior slope and posterior slope of the arch curve include varying thicknesses from the base of each slope to a crown of the arch curve. A greater base thickness of each anterior and posterior slope provides firm support of the respective anterior curve and posterior curve of a user's arch, with the crown being resiliently supportive of the user's arch during weighted and unweighted use. A means for tensioning having an adjusting means are connectable under the continuous arch curve between the anterior and posterior slopes, thereby allowing a user to adjust angles of the respective slopes and the tension along the arch curve for treating plantar fasciitis and other foot disorders.

Abstract: A criticality safe vacuum apparatus for removal of particulates from a gas having radioactive particles entrained therein. The apparatus includes a first staged segment including a cyclone housing and a second staged segment including a first filtration media for removal of particulates from gas. The cyclone housing is configured to accept insertion of a gas collection end of the second staged segment, and includes an intake port and an elongated length extended to a particulate collection container. Within the cyclone housing, cyclonic flow separates particulates from gas, with the gas moved by vacuum pressure into the first filtration media concurrently with particulates settling into the collection container. A third staged segment of a second air filtration media is positioned upgradient of the first filtration media.

Abstract: An arch brace orthotic includes an adjustable arch curve having a plurality of extensions separated by incisions which separate the arch curve surface into multiple resiliently cantilevered extensions. The extensions adjust the arch curve height and slopes during each foot-strike along the arch curve. The weighted arch curve height is returned to an unweighted height by flexibly rebounding of each extension to support the arch of the user's foot. A tensioning means is connectable under the arch brace, providing adjustment of the arch curve height and slope to therapeutically support the user's arch. The arch brace is movable without disassembly between any shoe for treatment of arch and foot disorders. A method of treating plantar fasciitis and related foot disorders includes selectively and periodically adjusting the arch curve height and slopes by manipulating the tensioning means for therapeutic support and user controlled strengthening of the user's arch and foot.

Abstract: An assembly for controlling the phase relationship between a crankshaft and a camshaft of an internal combustion engine with an outer ring member which is connectable to the crankshaft for receiving rotating torque therefrom and a hub which is connectable to the camshaft for transmitting torque from the outer ring member utilizes at least one elongated, centrifugally-responsive lever member which is pivotally connected to the ring member for pivotal movement relative thereto between radially inwardmost positions and radially outwardmost positions. Moreover, each lever member is connected to the hub so that movement of the lever member between the radially inwardmost and outwardmost positions effects a rotational shift of the hub relative to the outer ring member about the axis of rotation which alters the phase relationship between the crankshaft and the camshaft driven thereby.
