Abstract: In one embodiment, a processor includes: a plurality of cores each comprising a multi-threaded core to concurrently execute a plurality of threads; and a control circuit to concurrently enable at least one of the plurality of cores to operate in a single-threaded mode and at least one other of the plurality of cores to operate in a multi-threaded mode. Other embodiments are described and claimed.

Abstract: An acoustic signal generation system may include a cylindrical-like object having a cylindrical-like surface which is configured to reflect an acoustic signal directed to a location on the surface in substantially different directions as the cylindrical-like object is rotated. The cylindrical-like surface may be on the exterior of the cylindrical-like object or form an interior surface of the cylindrical-like object. The cylindrical-like surface may be formed by a plurality of substantially flat surfaces connected to one another in a substantially cylindrical configuration. The flat surfaces may have different angular orientations with respect to the axis of rotation. An acoustic transducer may be configured and oriented so as to direct an acoustic signal to a location on the cylindrical-like surface as the cylindrical-like object rotates. A motor may be configured to cause the cylindrical-like object to rotate.

Abstract: Apparatus for oxygenating the airway of a patient may include a device for delivering an oxygen-carrying gas into the airway, a fire detection system configured to detect indications of an imminent or incipient fire in the airway, and a fire suppression system configured to suppress the imminent or incipient fire in the airway in response to detection of the fire in the airway by the fire detection system. A drape for use during surgery on a patient may include a sheet configured to cover an area of the patient during surgery, a fire detection system attached to the sheet and configured to detect indications of an imminent or incipient fire beneath the sheet, and a fire suppression system attached to the sheet and configured to suppress the imminent or incipient fire beneath the sheet in response to detection of the imminent or incipient fire by the fire detection system.

Abstract: An instrument may continuously monitoring acoustic reflections from within and/or beyond an intubation tube positioned within the mouth of a patient while the patient is breathing. The instrument may include an acoustic reflectometer configured to detect the acoustic reflections. An acoustic flow channel may contain the acoustic reflectometer within it. The acoustic flow channel may be configured to acoustically couple the acoustic reflectometer to an end of the intubation tube, but to substantially block the free flow of expiratory gas from the end of the intubation tube through the acoustic flow channel. A gas flow channel may be separate from the acoustic flow channel and may be configured to allow the free flow of expiratory gas from the end of the intubation tube through the gas flow channel.

Abstract: A method, system and apparatus for Resonance-Based Acoustic Reflectometry that uses a hybrid approach. A method of manufacture, system and apparatus for a modified circle system that allows for the connection of extra devices like exemplary embodiments of the present invention.

Abstract: A medical device having an implantable instrument configured to be implanted in bone tissue, the implantable instrument having an internal chamber configured to house at least one transducer; a transducer located within the internal chamber of the implantable instrument, the transducer configured to transmit a signal and to receive one or more reflections of that signal; and a signal processing system configured to process the signals transmitted and received by the transducer so as to provide information indicative of the acoustic impedance of matter in the vicinity of the implantable instrument after it is implanted into the bone tissue based on the signals transmitted and received by the transducer.

Abstract: Determining the placement of an endotracheal tube in a patient. The invention evaluates discontinuities in the medium surrounding the endotracheal tube, such as the airway, as a function of distance past an end of the endotracheal tube. Using a loudspeaker to generate sound waves, the sound waves propagate through a coiled wavetube, a connecting adapter, and an endotracheal tube, into the area of interest. With a processing system, reflected sound waves which return from the cavity back to a microphone within the wavetube are analyzed and an area-distance curve of the area in interest is constructed.
