Abstract: A method for optimizing the performance of an athlete includes capturing an image of the athlete performing a biomechanical movement. A video signal is generated from the captured image. Ground reaction forces generated by the athlete are measured at the athlete's insoles and are transmitted as force data to a central processing unit. The force data is synchronized with the video signal by the central processing unit for display or storage.

Abstract: An arterial line emulator interfaces a non-invasive blood pressure monitor with an invasive blood pressure monitor. The emulator receives pressure waveform signals from the non-invasive blood pressure monitor, and receives a transducer excitation voltage from the invasive blood pressure monitor. The emulator converts the pressure waveform signal from the non-invasive blood pressure monitor into an analog signal which is scaled as a function of the excitation voltage. The scaled analog pressure signal is supplied as an input to the invasive blood pressure monitor, and emulates the signal which would be received from a catheter-based blood pressure transducer.

Abstract: A hand-held non-invasive blood pressure measurement device allows a varying pressure to be applied to an artery while pressure waveforms are sensed to produce pressure waveform data. Waveform parameters are derived from the sensed pressure waveform data. Blood pressure is then determined using the derived parameters. The user is guided or prompted to apply the varying pressure through audible and visual feedback.

Abstract: A non-invasive blood pressure sensor includes a first fluid filled sensing chamber having a diaphragm. A first transducer is fluidly coupled to the first sensing chamber to sense fluid pressure within the first chamber. A flexible body conformable wall surrounds the sensing chamber. The wall applies force to the artery while preventing pressure in a direction generally parallel to the artery from being applied to the sensing chamber. The flexible body conformable wall includes a second fluid filled chamber. A second transducer fluidly coupled to the second chamber senses fluid pressure within the second chamber. As varying pressure is applied to the artery pressure waveforms are sensed by the first transducer. Using output signals of the first and second transducers, the sensed pressure waveform data is analyzed to derive waveform parameters from which blood pressure values are derived. The effects of motion artifacts are reduced by the use of signals from both the first and second transducers.
