Abstract: A musical instrument or a more general multimedia input device in which an acoustic or otherwise measurable disturbance or change is made in a solid, liquid, or gas, is presented. In one embodiment, a Karman Vortex Street, or similar oscillatory vortex shedding phenomenon is formed in water, in association with each of a plurality of finger holes. Water flows past a branch point where it can eith er flow over a fipple, sharp edge or cylinder inside a pipe, or out a finger hole, t he finger hole being the path of least resistance for the water. Obsruction of the finger hole forces the water past an underwater whistle mechanism, causing vortex sheddi ng or an increase thereof. Blocking water from coming out of a given hole produces a given note, which, in some embodiments, is electrically amplified by a hydrophone. In one embodiment there is a separate hydrophone for each note, and the effect is enhanced by connecting each hydrophone to a separate bandpass filter set to the desir ed frequency of oscillation of each note. In other embodiments there is acousti c or electrical feedback to enhance resonance. Partial covering of a finger hole allows expressive manipulation of the tonality, microtonality, volume, and timbre of the instrument. In another embodiment the finger holes lead directly to a column of fluid, such that pressing the finger deeper into the finger hole shortens the column and increases the resonant frequency of each note. Some embodiments use acoustic signal processing such as frequency conversion to convert ultrasonic, audible, or subsonic vibrations or pressure changes in the fluid to produce audible sound at a desired frequenc y or in a desired frequency range. Embodiments with various kinds of acoustic or optical pickups, such as hydrophones or optical pickups such as laser interferometer s and optical imaging devices are disclosed. Other embodiments turn any fountain into a multimedia playground in which users can generate multimedia content by creating acoustic or refractive disturbances in water. Still other embodiments provid e a similar experience in other media such as solids, gases, and plasmas, throug h signal processing of physically-originated processes.

Abstract: Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire, provides enhanced ergonomics to the clinician, and may alleviate patient discomfort associated with the attachment and removal of ECG leads. The connector may be engaged and disengaged with little or no force imparted to the patient or the ECG pad, which significantly minimizes the risk of inadvertent dislodgement of the pad. In one embodiment the disclosed connector provides a thumb cam lever which affirmatively engages the press stud to the connector, and provides tactile feedback to the clinician that the connector is properly engaged. In other embodiments, the connector provides a pushbutton to enable the clinician to easily engage and disengage the connector from the ECG stud. The disclosed connectors may also decrease clinician fatigue, and may provide more reliable ECG results.

Abstract: System and methods for creating shaped, non-circular boreholes in rocks especially for use with geothermal heat pump applications and for increasing wellbore support in applications such as horizontal oil and gas drilling are described. The systems and methods when applied to geothermal heat pumps create an elliptical shaped hole that is optimized for placing heat transfer tubes with a minimum of grout used. The significantly reduced cross-sectional area of the elliptical borehole also increases the overall drilling rate in rock and especially in hard rocks. In horizontal hard-rock drilling, creation of a horizontal non-circular borehole or modification of a circular borehole to a non-circular geometry is used to stabilize the borehole prior to casing insertion, and may also allow the use of lower mud pressures improving drilling rates. The system uses a non-contacting drilling system which in one embodiment uses a supersonic flame jet drilling system with a movable nozzle that swings between pivot points. In a second embodiment the elliptical shaped hole is created by an abrasive fluid or particle bearing-fluid or air jet drill that moves between pivot points. In another embodiment a non-contacting drill can use dual parallel nutating nozzles that create a pair of overlapping circular holes. The non-circular shaped hole is created by either the high temperature flame or water-particle jet or chemically active fluid jet as it removes rock material by erosion, dissolution and or thermal spalling. Modifications of circular boreholes to a generally elliptical shape can also be done using milling or jetting techniques.
