Abstract: Disclosed is a system that includes a signal acquisition circuit to acquire a cuff pressure signal using an inflatable cuff, and to generate an oscillometric signal from the cuff pressure signal. The system also includes a user interface to enter one or more patient-specific detection threshold values, a memory to store the cuff pressure signal, the oscillometric signal, and the one or more patient-specific detection threshold values. The system also includes a microprocessor operatively coupled to the signal acquisition circuit, the user interface, and the memory. The microprocessor includes at least one algorithm to use the cuff pressure signal, the oscillometric signal, and the entered one or more patient-specific detection threshold values to calculate patient-specific readings of at least one of mean arterial pressure, systolic blood pressure and diastolic blood pressure. Related apparatus, systems, methods and/or articles are described.

Abstract: The present invention relates to a method and system in which a small stimulator unit which is designed to be mounted near the patient. A single cable connects the stimulator unit to the patient monitor. This cable both provides power to the stimulator unit, as well as 2-way data communication between the stimulator unit and the patient monitor. The patient monitor provides the user interface for the present invention, as well as other parameters such as heart rate and blood pressure.

Abstract: Methods and apparatus for the disposal of solid particulate material in subterranean formations penetrated by a borehole are disclosed. The invention includes, but is not limited to, the disposal of oil field waste and therefore provides means and methods for the disposal of virtually any type of waste slurry stream. A slurry is formed at the surface of the earth by mixing the solid waste in particulate form with liquid and preferably a viscosifier thereby forming a slurry. A borehole is drilled into a selected injection formation and the slurry is pumped or flowed "on vacuum" from the surface through the borehole and into the injection formation. Some surface pretreating of the slurry may be required including sizing of the particulate solids, adding weighting material, removing excessive amounts of oil and grease and diluting to reduce the level of radioactivity.

Abstract: A heartrate monitor of the invention includes a signal receiver adapted for being coupled to at least one sensor coupled to a medical patient, for providing an ECG signal and a pacemaker detection signal. A pacemaker activity checker, responsive to the pacemaker detection signal and the ECG signal provides first and second output signals, the first output signal indicating the occurrence of a QRS complex in the vicinity of the pacemaker detection signal, and the second output signal indicating the occurrence of an overshoot in the vicinity of the pacemaker detection signal. An overshoot validator, responsive to the ECG signals and the second output signal indicates the validity of the indicated overshoot. A QRS detector, responsive to the ECG signal, indicates the occurrence of a QRS complex in the ECG signal.
