Abstract: A tube occluder includes a body within which an end of the tube is attached; a twisting lug formed with or attached to the tube, the twisting lug including an outwardly extending shape; and a sleeve in rotational communication with the body, the sleeve including an internal profile that matingly engages the outwardly extending shape of the twisting lug, the sleeve rotatable relative to the body in a first direction such that the internal profile causes the twisting lug to twist the tube closed, the sleeve rotatable in a second direction such that the internal profile causes the twisting lug to twist the tube open. A tube occluding method includes enabling a user to rotate the sleeve relative to the body, causing the internal profile to turn the twisting lug and to twist the tube closed while the end of the tube remains secured within the body.

Abstract: A crane mat is disclosed having a plurality of panels of lumber positioned in alternating transverse directions with respect to one another, where the top and bottom panels are oriented parallel to the direction of vehicular traffic. The top and bottom panels may include a plurality of spaced apart grooves extending longitudinally from a first longitudinal end of the crane mat to a second longitudinal end of the crane mat for enhancing traction of a vehicle when traversing across the crane mat by transporting rain or moisture off the mat, or for receiving mud or other debris. The crane mat may include a plurality of edge protectors positioned on respective sides of the crane mat to protect the crane mat from handling damage. In various embodiments, the crane mat may be manufactured using either softwood, hardwood, or any combination of softwood and hardwood.

Abstract: An exemplary inventive subordinate oscillator array (SOA) includes two or more vibration attenuation devices (oscillators) that are sequentially arranged (e.g., via beams in the SOA) so that their respective anti-vibratory influences overlap. To design the SOA, an optimal number N of oscillators is calculated according to the equation N=?Q?, where ? is the modal overlap, Q is the quality factor, and ? is the desired fractional bandwidth. Each oscillator is akin to a conventional dynamic vibration absorber (DVA) and is characterized by its own mass, stiffness, damping, and geometry (e.g., length, width, and height). The respective characteristics of the oscillators are selected and the oscillators are distributed so that the SOA, when suitably attached to a vibrative structure, attenuates the vibrations of the structure so as to approximately flatten the structure's vibrations over a frequency band of interest.

Abstract: Methods, apparatuses, and systems for determining a correlation between intraperitoneal pressure (“IPP”) measurements and patient intraperitoneal volume (“IPV”) are disclosed. In an example, an apparatus is configured to determine a maximum fill volume of dialysate to be pumped into a peritoneal cavity of a patient. The apparatus also determines a plurality of iterations to achieve the maximum fill volume and a volume of the dialysate to be pumped for each of the iterations. For each iteration, the apparatus causes a dialysis machine to pump the dialysate to the peritoneal cavity based on the determined volume for that iteration, records IPP measurement output data from a pressure sensor, records or determines a total accumulated fill volume, and creates a data point for a personalized patient model corresponding to a correlation between the IPP measurement output data and the total accumulated fill volume.

Abstract: An intraperitoneal pressure (“IPP”) measurement apparatus is disclosed herein. In an example, the IPP measurement apparatus includes a transfer set or catheter that is fluidly coupled to a patient's peritoneal cavity and a pressure sensor adapted to contact the transfer set or catheter. The pressure sensor is configured to transmit output data indicative of an IPP within the patient's peritoneal cavity. The pressure sensor includes a pressure element configured to measure a pressure imparted by a fluid within the transfer set or catheter. The pressure sensor also includes a pressure amplifier having a first side that contacts a portion of the transfer set or catheter and a second side that contacts the pressure element. The first side has a greater diameter or surface area compared to the second side for amplifying the pressure signal for the IPP measurement.

The top and bottom panels may include a plurality of spaced apart grooves extending longitudinally from a first longitudinal end of the crane mat to a second longitudinal end of the crane mat for enhancing traction of a vehicle when traversing across the crane mat by transporting rain or moisture off the mat, or for receiving mud or other debris. The crane mat may include a plurality of edge protectors positioned on respective sides of the crane mat to protect the crane mat from handling damage. In various embodiments, the crane mat may be manufactured using either softwood, hardwood, or any combination of softwood and hardwood.

Abstract: A typical inventive device is self-contained and is designed for adjunctive placement at the unconnected end of a towed body in order to test dynamic motions of the towed body. The inventive device includes an IMU, a computer, wired/wireless communication electronics, a fluid-dynamically shaped member, and a cylindrical housing (which encloses the IMU, the computer, and the communication electronics). The housing is connected to the towed body aft of the towed body, and the shaped member is connected to the housing aft of the housing. Data is acquired that is indicative of the inertial dynamics of the towed body while in motion through a fluidic medium. Differently shaped members can be independently connected to the housing at different times, each influencing in its own way the inertial dynamics of the towed body and yielding its own set of data. Comparisons can thus be drawn between/among differently shaped members.

Abstract: An ambient wind Accelerating Wind Turbine is disclosed which exceeds the efficiency of prior wind turbines. Unique venturi with diffuser-injectors concepts are employed to speed up ambient wind flows into a high speed propeller for power generation improvements of 75% or greater. Applicants preferred Accelerating Wind Turbine embodiment comprises; an aerodynamically contoured venturi turbine shroud with a compression venturi inlet section; a ring of rotating blades, (i.e., a propeller) ; and a rear vacuum venturi section; with diffusers-injectors strategically placed in the venturi to ensure the smooth flow of accelerated air through and rearward of the venturi. Soft bird screens are located at the venturi openings to eliminate avian deaths. The Accelerated Wind Turbine can increase the power output of a wind turbine by a factor of two or more making wind power competitive in price to fossil fuel power.

Abstract: A service station advertising display system that allows users locally at the service station and remotely to request, upload, purchase and bid on advertising display time for displays located in the service station environment. Displays may be located on fuel dispensers or other locations proximate to where customers interact for requesting fueling, and other services such as convenience store and quick service restaurant purchases. The invention allows users to access available advertising times for displays, and bid or participate in an auction to control the display time. The user can upload their own content to be displayed, or use advertising content and tools located on servers to create content. The system resolves any conflicts with overlaps in different requests for advertising, downloads the content to the displays to be displayed, and tracks the effectiveness of the displayed content for billing and/or other purposes.

Abstract: Seismic data recorded by subsurface seismic sensors placed in a borehole, such as an oil or gas well, are transformed via a process of upward wavefield propagation to pseudo-receivers at the surface of the earth. The seismic data thus transformed can be processed as though the data had been recorded by the pseudo-receivers at the surface rather than in the borehole where the data were actually recorded. This method accurately accounts for seismic source statics, anisotropy, and all velocity effects between the real receivers in the borehole and the pseudo-receivers at the surface of the earth.
