Abstract: A roofing system incorporating lightweight concrete. The system includes a deck and an insulation board. Lightweight concrete is placed between the deck and the insulation board. The deck includes upper and lower flutes and the insulation board has a plurality of channels formed therein. The lower flutes and channels form ribs in the concrete layer that strengthen the roofing system. The concrete layer may be attached to the deck by a series of protrusions in the deck that extend into the concrete. Alternatively, the concrete layer may float above the deck to prevent cracking. A release agent may be used to prevent the concrete layer from adhering to the deck.

Abstract: True body composition is estimated using a dual-energy, fan-shaped distribution of x-rays and signal processing that corrects for mass magnification and other effects due to the geometry of the measurement system. To avoid inaccuracies due to beam hardening and certain other effects, the thickness of attenuating material along respective raypaths is obtained through using a four-dimensional look-up table derived experimentally from step-wedge measurements. To correct for mass magnification effects due to using a fan-shaped distribution of x-rays, another look-up table and interpolation between table entries are used to convert projected mass to true mass.

Abstract: An early warning leak detector. The early warning leak detector is placed in a hole is formed in the sealed deck of a roof. The early warning leak detector has an exterior shell having a nipple for connecting the early warning leak detector to a hose. Located within the exterior shell is a one way valve. The one way valve allows water to pass through the early warning leak detector while maintaining any negative pressure between the roof deck and the roof membrane.

Abstract: A roofing system for use with a cooled building. A first layer of insulation is attached to the roof deck using fasteners. A vapor barrier is formed over the fasteners. A second layer of insulation is formed over the vapor barrier. A board weighs down the second layer of insulation and a waterproof layer is formed over the board. The roofing system prevents thermal conduction into the refrigerated building while allowing the roof to be vented.

Abstract: A method of calibrating an ultrasound bone analysis apparatus having a pair of transducer assemblies. Each transducer assembly has a transducer and a coupling pad, and is movable relative to the other so that a face of each pad can be moved to a position in which they mutually contact and to a position where the faces contact body parts. The method according to the present application includes transmitting an ultrasound signal from one transducer and receiving a signal corresponding to the transmitted ultrasound signal through the other transducer when the transducer assemblies are in the first position and the second position. A time for the ultrasound signal to pass through the body part is determined, and a width of the body part based on positions of the transducers is determined. Then, using the time and width values a speed of sound of the ultrasound signal passing through the body part with squish compensation is calculated.

Abstract: A laterally air permeable roof assembly having seals at perimetrical edges of the roof and at all penetrations of the roof assembly includes secondary air seals spaced from the perimetrical air seals and the protrusion air seals such that the secondary air seals are isolated from unstable areas of the roof. The unstable areas of the roof are areas which experience a high degree of expansion and contraction in different planes.

Abstract: A method and apparatus for surveying and reporting listener opinion of a list of songs such as the songs comprising a radio station music library. A group of music listeners is selected from whom individual listener opinions are recorded. A home music preference test kit is fielded to the select listeners for use in each listener's residence. Data from each music preference test kit is then collected, compiled and tabulated to reflect a mean or average listener opinion for each song in the list.The home music preference test kit includes instructions for completing the test and returning the survey form, a music medium having a preselected number of song hooks representing each song in the library of the radio station. The kit also includes a survey form for recording the listener's opinion of each song based on the song hooks and an honorarium for agreeing to properly complete a survey form.

Abstract: Single and dual-energy x-ray images are obtained in a single scanning procedure, which allows measurement of bone density from the scan information acquired at both energy levels and high resolution digital geometric images from one of the two energy level scan sets. Densitometric and geometric measurements taken from multiple projections may be combined to create three-dimensional densitometric and tomographic images. An interface device allow an operator to select one of a plurality of scanning sequences which correspond to scanning a set of regions of interest in the patient.

Abstract: Disposable intra-arterial augering and dottering-instruments for use in patients in clearing pathways at obstructed or nearly obstructed arterial sites are disclosed. A number of augering tips used on the instruments are disclosed along with a method for releasibly affixing augering tips to the instruments. In addition, a dottering tip is disclosed for use in procedures where it is desired to open a pathway without excising material from the obstructed site. A combined augering and dottering tip is disclosed for a procedure in which material displacement followed by excising of material from within an artery is accomplished without removal of the combined augering and dottering tip until the procedure is complete.

Abstract: Roofing system is presented comprising a built-up roof(BUR) assembly or modified roof membrane assembly (MRM) which is adhered to gypsum, concrete or composite sheets or panels which have been loose-laid over a roof substrate. This allows the BUR or MRM assemblies to conduct heat to or receive heat from the thermal mass of the loose laid mass-weighted sheets immediately below the BUR or MRM assemblies. The gypsum panels, preformed concrete panels, poured-in-place concrete or composite mass-weighted construction panels which are placed between the BUR or MRM assemblies and the roof substrate causes more gradual changes in temperature between the roof assembly and the roof substrate.

Abstract: Novel apparatus and related methods are disclosed by which plaque is connected to the head of a removal instrument for removal of a unitary segment of plaque from an artery intact to increase blood flow through the artery.
