Abstract: Method and apparatus for detecting possible interference in a neurological signal received from a monitoring element of a medical device system. The monitoring element monitors a condition or a symptom of a nervous system disorder being treated and provides a neurological signal to the medical device system for purposes of providing closed-loop feedback control. The system analyzes various parameters of the received signal by taking instantaneous measurements of data points in moving window and thereby determining whether the signal is of poor quality. If the signal is of determined poor quality, it is removed from consideration in the closed-loop feedback control system until it is determined that the signal quality has sufficiently been restored.

Abstract: A method of analyzing biological pressure signals in a patient including obtaining arterial blood pressure, cerebral blood flow rate and intracranial pressure signals from the patient, and analyzing frequencies of the signals in relation to a range of target frequencies corresponding to at least one of type-B slow waves, infra-B waves and ultra-B waves; and an apparatus for analyzing biological pressure signals in a patient including an acquisition module, located adjacent to the patient and having input channels that receive signals from an arterial blood pressure (ABP) sensor, a cerebral blood flow rate (CBF) sensor, and an intracranial pressure (ICP) sensor; an analysis module that performs frequency analysis of the signals from a target frequency selected from the group consisting of type B slow waves corresponding to a frequency between 8×10?3 hertz and 50×10?3 hertz, infra-B waves corresponding to a frequency lower than 8×10?3 hertz, and ultra-B waves corresponding to a frequency including between 50×10

Abstract: A cough event is differentiated from a sneeze event of a test subject enclosed within a plethysmograph test chamber by measuring air pressure changes during the event, and comparing the pressure changes against criteria indicative of a cough to determine the likelihood that the event is a cough. Air pressure changes are recorded as pressure and/or sound values. A graphical record of a waveform of changes in the air pressure during an event relative to a baseline value is recorded, and a value is calculated that is indicative of the likelihood that the event is a cough based on the sizes of areas between the waveform and baseline during the event, said areas including a first area indicative of the change in air pressure during air inspiration, a second area indicative of the change in air pressure during air compression, and a third area indicative of the change in air pressure during expiration.

Abstract: A system and method are disclosed for noninvasively diagnosing limb compartment syndrome by measuring a quantitative modulus of hardness. In the preferred embodiment, a nonmovable pressure probe mounted in the center of a movable spring loaded platform is applied against a limb compartment. Force is gradually applied to the probe and the platform, compressing a limb compartment. Pressure on the probe is measured as the probe pushes into the limb. The spring loaded platform displaces, and the distance of the probe tip to the platform is measured. This distance is the depth of compression into the limb by the probe. The relationship of incremental pressures in the probe and the corresponding distance of the probe tip to the platform for each pressure is plotted. A linear regression analysis is preformed whose slope forms a quantitative modulus of hardness.

Abstract: A method of assessing the neuro-psycho-physical condition of a person includes acquiring, by a self-contained hand held instrumentation, reaction times, execution times and ergometric data of actions performed by the person carrying out a certain test. This test includes processing the time data and the ergometric data for calculating the power exerted in performing each action. Data on the reaction time and the exerted power is processed on the basis of certain software to produce information on the neuro-psycho-physical condition. The ergometric data and reaction time data are processed by a fuzzy logic processor. The hand held instrument may optionally include also motion and voice articulation classifiers.

Abstract: Bone tissue fragments are collected from liquid fluid being evacuated by suction from a surgical operation in bone tissue. Liquid is allowed to pass into a cylindrical sieve through one open end thereof and through the sieve wall from the inside to the outside thereof. Bone tissue fragments are collected on the inside surface of the sieve and are scrapped off and deposited outside the sieve.
