Abstract: A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.

Abstract: The system obtains SOH of a first component, where the SOH indicates a difference between a current state of the first component and a state of a rated new component. The system obtains historical use of the first component. Based on the SOH and the historical use, the system determines a future SOH of the first component. The system obtains an indication of a requested SOH of the first component. Based on the indication of the requested SOH and the future SOH of the first component, the system determines a first time indicating when the first component will need to be replaced. The system determines a second time indicating when the second component is available to replace the first component, where the second time occurs before the first time. The system requests a delivery of the second component when the second time is substantially close to the first time.

The balm mixture includes a carrier portion and an active ingredient portion which will cause tears to form in the eye of a user adjacent the application thereof, thereby alleviating a dry eye condition.

Abstract: A saw blade includes an elongated body with a working edge extending along a longitudinal axis. A first strip composed of carbide or cermet and including at least one first full cutting tooth is coupled to a first portion of the working edge by a first weld fusion zone composed of a ductile material. The first strip is set in a first direction at a first angle out of a plane of the body by a first bend in the first weld fusion zone. A second strip composed of carbide or cermet and including at least one second full cutting tooth is coupled to a second portion of the working edge by a second weld fusion zone composed of a ductile material. The second strip is set in a second direction, opposite the first direction, at a second angle out of the plane of the body by a second bend in the second weld fusion zone.

Abstract: A hole cutting accessory for a power-driven tool may include an arbor that provides for quick release of an annular saw blade component of the accessory, and for quick release of a pilot drill bit component of the accessory. The quick release of the annular saw blade component from the arbor may be accomplished separately from the quick release of the pilot drill bit component from the arbor.

Abstract: A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially-elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.

Abstract: An anti-rotation device is provided for stringing a cable or wire while reducing a twisting moment of the cable or wire as it is strung. The device includes a tow component, having multiple tow sections pivotally connectable end-to-end. A plurality of insulated weighted tail components are suspended so as to hang from the tow component. Each of the insulated tail components include weighted tail sections releasably connectable end-to-end to one another. At least one electrically insulated tail section is provided in each insulated tail component between the tow component and the weighted tail sections. The tail components are constrained to only articulate relative to the tow component in the single plane of bending of the tow component.

Abstract: A holesaw system comprises a holesaw including a base and a generally cylindrical wall with a proximal end coupled to the base and a distal end with a cutting edge; a pilot drill bit including a front cutting tip, a rear shank portion, and an intermediate portion between the front cutting tip and the rear shank portion; and an arbor coupleable to the holesaw and to the pilot drill bit. The arbor is configured to be operable in a first mode in which the holesaw and the pilot drill bit are rotatable in unison to form a hole in a workpiece and in a second mode in which the pilot drill bit is rotatable independently of the holesaw to remove a plug of material from the holesaw.

The working portion has a generally planar wedge shape bounded at least partially by a rear non-cutting end with a first width, a front cutting edge opposite the rear edge with a second width that is greater than the first width, a first side cutting edge extending from a first end of the rear end to a first end of the front cutting edge at a first angle to the longitudinal axis, and a second side cutting edge opposite the first side cutting edge and extending from a second end of the rear end to a second end of the front cutting edge at a second angle to the longitudinal axis.

Abstract: Disclosed herein is a method of generating a map based on ground penetrating radar (GPR) scans including receiving GPR data corresponding to multiple path of travel of one or a plurality of moving devices and/or surfaces. Some of these paths of travel overlap at least some others and some of these paths of travel are independent of one another. Where overlapping is determined, GPR data is combined to form a higher resolution and/or more accurate determination of physical properties of a subsurface. Further, the resolution can increase with each scan of a particular area and the technology can be used in conjunction with a separate positioning system like a GPS and/or replace the separate positioning system when the resolution is sufficiently high for a portion of the surface.

A response may be generated by the voice-capturing device or an associated service provider system based on the contextual information determined from the parsed meeting invitation and/or related sources.
