Abstract: A system for preventing obstruction of an airway includes an internal component and an external component in embodiments described herein. The internal component can include an electrical coupling configured to extend to a muscle or nerve, and an access port electrically connected to the electrical coupling. The external component can include an access port counterpart configured to engage with the access port to provide an electrical connection, and a power supply. The power supply can provide power to the access port counterpart and the electrical connection, thereby powering the electrical coupling at the muscle or nerve to prevent obstruction of an airway due to obstructive sleep apnea.

Abstract: Embodiments relate to systems and methods for delivery of oxygen or other treatment gases to a patient without requiring physical contact or enclosure of the patient. Embodiments can include a delivery hood, sensing components, and a gas distribution system including one or more gas delivery ports. Gas delivery ports may be individually controlled based on input from the sensing components to alter the volume and orientation of treatment gas flow directed at a patient. Sensing components can include cameras or other sensors that detect the position of a patient's head, and gas delivery ports may then be controlled to direct treatment gas flow in the direction of the patient's head. Embodiments and methods described thereby allow for efficient oxygen or other gas delivery to a patient without requiring contact or enclosure of the patient.

Abstract: A system for detecting the location of an exit point of an object in a person's body includes a feeding tube, and a light source configured to generate light coupled to a light transmitting element. The light transmitting element transmits the light through an exit point. A light source sensor detects the light and a signal is generated indicating the detection of the light. A method for using the system includes inserting a feeding tube into a patient and generating light that is transmitted to an exit point. Detecting light transmitted from the exit point and generating an indicator signal as a function of the detected light.

Abstract: A piggyback IV administration system uses a solenoid actuated sequence valve to control the flow of fluid from a pair of IV fluid sources to the inlet of an IV pump or controller. The sequence valve pinches off a first tube while allowing fluid to flow through the second tube and then, in response to a control signal, changes state so that the second tube is pinched off and fluid can flow through the first tube unimpeded. Improper placement of the first and second tubes within the sequence valve during setup is prevented.

Abstract: A piggyback IV administration system uses a solenoid actuated sequence valve to control the flow of fluid from a pair of IV fluid sources to the inlet of an IV pump or controller. The sequence valve pinches off a first tube while allowing fluid to flow through the second tube and then, in response to a control signal, changes state so that the second tube is pinched off and fluid can flow through the first tube unimpeded. The sequence valve automatically senses conditions which indicate a failure of the sequence valve to occlude the second tube when the valve changes state.

Abstract: A laser scanning flaw direction inspection system is provided for simultaneously scanning a plurality of laser sources across a moving web of material being inspected. The plurality of laser beams are simultaneously scanned utilizing a common scanning apparatus. Laser beam radiation from the plurality of laser sources is collected from the web of material being inspected and detected for generating signals based on the integrity of the radiation applied to the detector from the material being inspected. The plurality of laser sources are preferably of different wave lengths, may have different spot sizes and may be separated by a fixed distance in either the scanned direction or in the direction of web travel. By providing such flexibility in size, positioning and wavelength, and using optical filters to separate the signals related to each of the sources, different types of flaws as well as different information may be generated which would not be possible using a single source system.

Abstract: A web of moving material is successively scanned by a light source, such as a laser beam, and changes of intensity of the transmitted, reflected or scattered light from the material is detected to provide an indication for discerning flaws in the web. A once per scan line digital signal from the scanner controls a voltage controlled oscillator connected in a phased locked loop which is used for controlling the generation of a precision ramp analog voltage that follows the angular scan position of the light source on the material. The light signal from the web is applied to a comparator for providing a digital pedestal signal in which the first light passing the comparator is the leading edge of the web while the last light passing during a scan line is the trailing edge or the end of the web. If no pedestal signal is present indicative of a break in the web, a synthetic maximum width pedestal signal is substituted to enable the inspection system to continue to function.

Abstract: A rotary scan flaw detection system is provided in which a record medium is driven synchronously with the scanning of a source of radiation across the surface of material being examined for flaws. A method and apparatus are provided for dividing the material into discrete segments or strips so that flaw information obtained from scanning the material may be sorted and routed pursuant to a predetermined plan. A grating is scanned having predetermined marks thereon which are recorded on the record medium. The material is then scanned, the marks played back, and fed to a data routing logic circuitry along with the flaw information derived from the surface of the material being examined, so that the flaw information is automatically routed in accordance with the occurrence of flaws on discrete segments of the material.
