Abstract: Devices, networks, systems, methods, and processes for calibration of barometric sensors in the devices are described herein. A device may include a barometric sensor for measuring an observed pressure value at a geolocation of the device. The device can receive one or more reference pressure values from multiple sources. The device may compare the one or more reference pressure values with the observed pressure value to determine an offset pressure value. The device can calibrate or re-calibrate the barometric sensor based on the offset pressure value. The device may determine an altitude value based on the observed pressure value. The device can further optimize the altitude value after calibration of the barometric sensor. The device may dynamically re-calibrate the barometric sensor to adapt to changing environmental conditions in real-time. The device may also periodically re-calibrate the barometric sensor to reduce or eliminate an effect of drift in the barometric sensor.

Abstract: A die and method for extruding an extrudable material to form an extruded member is described. In one embodiment, the die comprises a barrier member comprising a plurality of feed channels that extend through the barrier member. Furthermore, the die incorporates a passage forming member extending from the barrier member substantially in the direction of extrusion. The feed channels are arranged with respect to the passage forming member to allow the extrudable material to substantially flow about the passage forming member to form a corresponding passage in the extruded member.

Abstract: Systems, methods, apparatuses, and software for providing enhanced measurement and correction of physiological data are provided herein. In a first example, a physiological measurement system is configured to obtain a measured photoplethysmogram (PPG) for a patient, and obtain a reference signal for the patient measured concurrent with the measured PPG, the reference signal including noise components related to at least motion of the patient. The physiological measurement system also is configured to determine a filtered PPG from the measured PPG using at least an adaptive filter with the reference signal to reduce noise components of the measured PPG, determine a final PPG by spectrally subtracting at least a portion of the noise components of the reference signal from the filtered PPG, and identify one or more physiological metrics of the patient based on the final PPG.

Abstract: Systems, methods, sensors, and software for providing enhanced measurement and correction of physiological data are provided herein. In one example, a capacitive sensor of a measurement system is positioned onto tissue of a patient. The capacitive sensor includes one or more conductive elements with associated gain properties that are positioned near optical sensor elements proximate to the tissue of the patient, the optical sensor elements positioned to measure a photoplethysmogram (PPG) for the tissue. The measurement system drives the capacitive sensor and measures capacitance signals associated with the capacitance sensor. The measurement system corrects for at least motion noise in the PPG using the capacitance signals.

Abstract: A display apparatus can include a substantially self-supporting panel adapted to be erected and used without the use of a support frame. In one embodiment, a frameless display fixture includes first and second panels fastened to one another proximal their upper edges, recesses adapted to receive retail merchandise integrally formed along a front side of the panel, and mating portions proximal their lower edge which interlock with a substantially rigid base unit such that the lower edges of the panels are held a fixed distance from one another. The first and second panels may be substantially mutually self-supporting so as to form a frameless display fixture.

Abstract: Heat exchanger assemblies, and, in particular, heat exchanger assemblies that function in high pressure and/or temperature environmental conditions, are described. An essential feature of the heat exchanger assembly is the presence of an hybrid tank comprising both plastic or plastic like materials and metal or metal alloy materials, that provides for good structural integrity and operation of the assembly under high pressure and/or temperature conditions.

Abstract: Underwater power generation for an underwater vessel is provided when the vessel transits through an underwater thermocline. At least a portion of the shell of the vessel is made from a thermally conductive material. Thermo-to-electric energy converters are electrically coupled together with each converter having a first surface thermally coupled to the shell's inner surface. A phase change material is thermally coupled to each opposing second surface of the converters. The phase change material has a phase change temperature that is between the upper and lower temperature extremes of the underwater thermocline's temperature range. The converters generate electrical power as the underwater vessel transits through the underwater thermocline.

Abstract: A system and method for providing insurance protection against loss of contributions to tax favored defined contribution plans should an active employee/participant become disabled. The invention manages the administration of a disability insurance policy held inside the plan that continues contributions to the plan during a period of disability, where the coverage amount for each participant is determined by the level of contributions made by, or for, each participant.

Abstract: An apparatus and method for creating a frequent shopper type or consumer affinity type relationships for remote consumer transactions where the consumer creates a remotely accessible library for affinity type shopping memberships for use in remote shopping for creating efficient access to a consumer's favored shopping locations. The locations can be easily accessible on the consumer's computer system by way of a toolbar having a shopping link or hyperlink.

Abstract: A radio frequency (RF) power combiner for connecting multiple base transceiver stations with one antenna assembly includes at least one combinational logic device coupled to at least two base transceiver stations for combining signals generated thereby into a combined signal for being transmitted by the antenna assembly. At least one frequency selective RF power detector is coupled to one of the signals generated from one of the base transceiver stations for generating an output indicating whether the signal at a predetermined frequency is present. A logic control module is coupled to the frequency selective RF power detector for generating a control signal in response to the output of the detector. An oscillator is coupled to the logic control module for generating a carrier signal at the predetermined frequency for the combined signal in response to the control signal.

Abstract: A matting system for framing, archiving and displaying display items having a display board with window openings, a carrier board with window openings in line with and slightly larger than the window openings of the display board. The carrier board having hinged doors, which fit into the window openings and a backer board which holds the doors of the carrier board closed so as to maintain the display item between the door and a frame extension created between the dissimilar sized openings of the display board and the carrier board.

Abstract: A cutting board comprises a first member having a first predetermined shape and a predetermined thickness. The first member has at least two outer edges engageable with at least two radially opposed sides of a support member. The first member having sufficient cut resistant properties and heat resistant properties for cutting at least one of hot and cold food products thereon and having sufficient strength to support such food products to be cut. There is a first surface of the first member having a first predetermined size for holding such food products to be cut and a second surface of the first member having a second predetermined size. A means is provided for allowing juices from such food products to be cut to drain from the cutting board.
