Abstract: A method of non-invasively measuring venous oxygen saturation, comprising: applying a pressure transducer at a first site on a body, applying a drive signal to the external pressure transducer at a predetermined frequency, to cause a series of pulsations of a predetermined magnitude in the venous blood volume in the vicinity of said first site, applying an oximeter device at a second site on the body, measuring output signals received from said oximeter device, said output signals containing a component representative of the modulation of venous blood volume due to said pulsations, deriving a measure of venous oxygen saturation from the frequency response of said output signals.

Abstract: A real-time workload information scheduling and tracking system and related methods are disclosed that greatly facilitate production operations. Real-time views can be displayed at a variety of time period granularities (e.g., daily, weekly, monthly, quarterly, yearly, etc.) showing completion status for tasks and sub-tasks that have been assigned by the system to individual worker resources to accomplish all aspects of the production process. The processes are laid out in a series to allow so that project task priorities can be set and worked out in a specific order. A central location is also provided to document and track all schedule impacts, as well as quality notifications, held-for records, and discrepancy records written against the tasks or sub-tasks being displayed.

Abstract: A dispenser for rolled absorbent web material is disclosed. A carriage is rotatable between at least two orientations. The carriage includes a first roll holder, which holds a first roll of absorbent web material in a primary position when the carriage is in a first orientation and in a secondary position when the carriage is in a second orientation, and a second roll holder, which holds a second roll of absorbent web material in the secondary position when the carriage is in the first orientation and in the primary position when the carriage is in the second orientation. A roll sensor senses the amount of absorbent web material remaining on the roll in the primary position. A feed mechanism dispenses absorbent web material from at least one of the rolls. A transfer mechanism feeds absorbent web material from the roll in the secondary position into the feed mechanism when the absorbent web material on the roll in the primary position is nearly depleted.

A tilting motor is provided to the base frame and has a pair of output shafts influencing the orientation of the support platform, whereby rotation of the output shafts in a first direction tilts the support platform only along a first axis, and rotation of the output shafts in a second direction tilts the support platform only along a second axis. A power supply is provided for driving the tilting motor.

Abstract: A versatile saw horse having dual setup orientations for use by a tradesperson is disclosed. The saw horse includes a hinged structure which provides an open position and a closed position for the saw horse, where the hinged structure has a first hinged member connected to a second hinged member by a hinge. First and second legs laterally extend from the first hinged member, and third and fourth legs laterally extend from the second hinged member. A first side leg laterally extends from the first leg, a second side leg laterally extends from the third leg, and at least a third side leg laterally extends from the hinged structure. In a first setup orientation of the saw horse, the first, second, third, and fourth legs have support ends configured to provide a stable support for the saw horse over a planar support surface.

Abstract: Multi-band, Inverted-F Antenna with capacitively created resonance, and radio terminal using same. The present invention creates an additional resonance frequency in a planar-style, inverted-F antenna (PIFA), such as that typically used in mobile radiotelephone or other types of radio terminals. A first radiating branch of the antenna is connected to the signal feed conductor and the ground feed conductor. A second radiating branch is connected to the signal feed conductor and the ground feed conductor at one end and is capacitively coupled to the first radiating branch at the other end so that the antenna resonates at an additional resonance frequency. The additional resonance frequency can be used for, among other things, adding GPS or Bluetooth functionality to a radiotelephone terminal that otherwise operates on GSM (Global System for Mobile) or other mobile radiotelephone terminal frequencies.

Abstract: Selectively engaged antenna matching for a mobile terminal. Antenna matching can be engaged, disengaged, or switched as needed depending on whether a movable cover or clam-shell portion of a mobile terminal is open or closed. A switch can connect a single matching network to a radiating element in one case, and disconnect the single matching network from the radiating element in the other case. Alternatively, the switch can connect one matching network to the radiating element to achieve one matched condition, and the other matching network to the radiating element to achieve the other matched condition. In other embodiments, a switchable matching arrangement can alter the signal and/or ground feed points of an antenna. The technique can be applied to planar, fixed external, or collapsible antennas.

Abstract: A drilling fluid or mud additive having several components, including leonardite (humic acid); potassium acetate; partially hydrolyzed polyacrylamide (PHPA); polyanionic cellulose polymer (PAC); sulfonated asphalt; sulfoalkylated tannin; polystyrene maleic anhydride copolymer; micronized cellulose fiber; and calcium carbonate. These components are preferably premixed in a dry formulation as a powder or as pellets, and shipped to the site in bags or bulk tanks. This offers substantial advantages over the prior art in that the drilling mud of the present invention may be formed simply by adding the dry mix to a predetermined amount of water, and is thus much easier to make than the prior art wet mix drilling fluids, which typically require precise ratios of several different powders and liquids to be mixed together. Hydration buffers help keep the powder or pellets dry and flowable.

Abstract: A Hall effect sensor assembly including a Hall effect sensor; an overmolded housing which is overmolded onto the Hall effect sensor; and a magnet movably connected to the Hall effect sensor by a movable connection with the overmolded housing. The movable connection restrains movement of the magnet to a path along and aligned with a Hall effect central sensing axis. The magnet is substantially prevented from tilting relative to the sensing axis.

Abstract: A method for controlling the foam produced when a molten material encounters reduced pressure in a vacuum chamber includes passing the molten material through an aging zone in the vacuum chamber in which the molten material is allowed to drain from between the bubbles of the foam and then collapsing the bubbles of the drained foam.

Abstract: A paper dispenser including a carriage that is rotatable between at least a first orientation and a second orientation. The carriage holds at least two rolls of paper. In the first orientation, the first roll is in a primary position and the second roll is in a secondary position. In the second orientation, the first roll is in the secondary position and the second roll is in the primary position. A roll sensor senses the amount of paper remaining on the roll held in the primary position. Paper from at least one of the two rolls is fed into a feed mechanism for dispensation. A transfer mechanism feeds paper from the roll held in the secondary position into the feed mechanism when the roll sensor senses that the paper on the roll held in the primary position is depleted to less than a predetermined diameter.
