In one embodiment, the present invention provides a system to deliver at least one therapeutic gas to a spontaneously breathing patient, wherein the rate of delivery of the at least one therapeutic gas exceeds the patient's inspiratory flow rate, and the amount of the at least one therapeutic gas that is wasted is minimized or eliminated.

Systems for inhalation of therapeutic and diagnostic gas and methods of use thereof

A system, method and circuit restricts the amount of a first fuel being provided to a duel-fuel engine, for example a diesel-natural gas engine; wherein a secondary circuit is provided, in parallel, to the circuit formed between the engine control unit, first fuel injector, and ground comprising a dummy load, and a normally closed switch inserted in the first fuel injection circuit; such that when the normally open switch is in a closed state the dummy load provides a resistance to the second sub-circuit, such that a total resistance in the second sub-circuit is equal to a total resistance in the first sub-circuit when the normally closed switch is in a closed state.

Mixed fuel engine

The present invention provides for an analog audio patchbay comprising a first plurality of connectors capable of receiving a plurality analog electronic signals, a second plurality of connectors capable of transmitting a plurality of analog electronic signals, and a circuit board extending from the first plurality to the second plurality.

A thermal cycling method and associated device is described. The method is for carrying out a polymerase chain reaction (PCR) process to amplify deoxyribonucleic acid (DNA), and the method includes: pre-heating a series of blocks to respective temperatures that correspond to different respective heating stages in a PCR process, in which each block of the series of blocks defines a respective heat transfer surface, in which the series of blocks define a sequence of positions along a path, with each position defined by a respective heat transfer surface of a respective block; and moving a PCR reaction vessel, which contains deoxyribonucleic acid (DNA) and PCR reagents, along the path into and out of each respective position in the sequence of positions according to a schedule, in which, at each respective position the PCR reaction vessel is in thermal contact with the respective heat transfer surface to equilibrate a temperature of the PCR reaction vessel to a target temperature that corresponds to a respective heating stage in the PCR process.

A means and method for enabling contact or touch point location detection to be implemented on a particular garment. This means and method simplifies the design of the garment by reducing the number of conductors required to interconnect the various touch points and signal processing circuitry; it provides a way to dynamically reposition or resize the effective touch point target regions; and it provides for new control capabilities by optionally allowing continuously variable user input control.

Resistive loop excitation and readout for touch point detection and generation of corresponding control signals

Gas packages for the delivery of therapeutic gases, and in particular gaseous nitric oxide (gNO) are provided herein. The gas packages comprise one or more of a gas reservoir, interface layer, sealing layer, and holding container. The interface layer regulates discharge of the therapeutic gas from the gas reservoir to the external environment. The sealing layer and/or holding container prevent evolution of the gas until the sealing layer is compromised or the holding container is opened. The gas packages and methods for using them are useful for the treatment, alleviation, and prevention of various disease and non-disease, medical and non-medical, conditions in humans and animals.

In a nondestructive testing system, a preamplifier is connected to a piezoelectric element and is tuned to optimize the amplitude of a signal input to the piezoelectric element and the shape of a response signal. A receiver amplifier couples the signal received from the piezoelectric element to an ultrasound system.

A system controls and manages administration of a therapeutic gas, such as NO, O, or the like, to a spontaneously breathing, non-ventilated patient such that concentrated NO is as low as reasonably possible while delivering the desired amount of NO to the distal portions of the lungs. The system includes an entrainment cell that provides remote, turbulent mixing with low temporal latency and can be used with a nasal cannula or a mask. The entrainment cell uses room air to dilute the therapeutic gas; however, supplementary gases can also be used. A baffle can be included to promote mixing and a flow sensor can also be used if desired. Multiple ports can be included in the entrainment cell. An equalizing valve is also disclosed.

System and elements for managing therapeutic gas administration to a spontaneously breathing non-ventilated patient

Therapeutic gas, such as NO, is delivered to a patient in accurately controlled amounts by a system that uses a closed loop feedback system in which the amount of therapeutic gas delivered is a precise fraction of the total gas delivered to the patient. Ratiometric feedback is used in the control loop.

An imaging system for white light and fluorescence endoscopy that includes an automatic gain control circuit that adjusts the brightness of an image produced based on distribution of pixel intensities in one or more video frames. The magnitude of the image signals produced by a pair of high sensitivity imaging devices such as intensified CCD transducers are compared to a number of reference thresholds. A time-over-threshold counter ( ) determines the number of pixels in the image signals having magnitudes greater than or less than the reference thresholds. The distribution of pixel intensities is supplied to a decision tree algorithm ( ) that determines whether the gain of the-intensified CCD transducers ( ) used to produced the autofluorescence images or the intensity of the excitation light produced by a light source ( ) should be increased or decreased. In addition, a mode switch mechanism is provided to change rapidly from the fluorescence imaging mode to the white light imaging mode or vice versa. This mechanism includes provisions to prevent the accidental application of reflected white illumination light to the image-intensified CCD transducers. Proximity switches ( ) monitor the position of a light directing mechanism such as a mirror ( ) to allow light to pass to fluorescence camera head ( ) or to a color video camera head ( ). The light source is not switched to produce white light until it is known that the mirror is in position to direct the reflected light to the color video camera head. Finally, the present invention produces a quantitative display of the relative intensities of the autofluorescence light produced in a pair of spectral bands.
