A method of determining the perceptual load of a human brain. The perceptual load is induced by a predetermined task carried out by the human. The method includes the steps of: measuring with a functional near-infrared spectroscopy (fNIRS) sensor device a metabolic activity of the human brain while the task is carried out and determining the perceptual load as a function of a measured change in metabolic activity. The invention further relates to a method of determining the level of stimulus perception corresponding systems.

In one embodiment, a system for finger-to-thumb crease testing includes a patient interface configured to attach to a thumb of a patient, the patient interface including a touch sensor configured to sense contact between a finger of the patient and the touch sensor, the touch sensor being positioned on the patient interface in a location at which it overlies a distalmost thumb crease of the thumb when the patient interface is attached, and a control module in electrical communication with the patient interface, the control module being configured to count a number of times the patient successfully taps the touch sensor with the finger.

A bipolar stimulation probe includes a first electrode, a second electrode, a control module, and switches. The control module is configured to stimulate nerve tissue of a patient by generating (i) a first output signal indicative of a first pulse to be output from the first electrode, and (ii) a second output signal indicative of a second pulse to be output from the second electrode. The first pulse and the second pulse are monophasic. The switches are configured to output from the bipolar stimulation probe (i) the first pulse on the first electrode based on the first output signal, and (ii) the second pulse on the second electrode based on the second output signal.

The invention provides an electroactive material (preferably electroactive polymer) sensor system, comprising an electroactive material sensor (22) and a control system (28) for performing measurements relating to the impedance of the electroactive material sensor at at least first and second different frequencies. From these measurements a temperature at the sensor and an external pressure or force applied to the sensor can be determined. The sensor can thus be used as a pressure sensor and as a temperature sensor. When used in combination with actuation, an electroactive material actuator with integrated temperature sensing functionality is able to measure the temperature at the exact actuator position, which is always closer than an external thermocouple.

The present invention employs an information processing apparatus, comprising: an information processing unit configured to: acquire concentration information, which indicates a spatial distribution of concentration of a substance constituting an object and which originates from a photoacoustic wave generated by light irradiation of the object; and correct, based on the concentration in a specific position of the object in the concentration information, the concentration in a deep region of the object deeper than the specific position in the concentration information.

A catheter has a distal assembly with at least one loop with ring electrodes. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and a U-shape bend therebetween. The U-shape bend is anchored at a distal end of a deflectable section which is reinforced by at least one washer having at least two holes, each hole axially aligned with a respective lumen in the deflectable section. Each hole is centered with a lumen so that each puller wire portion therethrough is straight and subjected to tensile force only. A proximal end of the support member is flattened and serrated to provide a better bonding to the distal end of the deflectable section.

A defibrillator produces a biphasic defibrillation pulse waveform with adjustable tilt for the second phase. The tilt of the second phase of the biphasic waveform can be controllably adjusted by selectively switching a current path which bypasses the patient during delivery of the second phase of the pulse. The inventive biphasic waveform can be delivered by a defibrillator with a single capacitance.

A method and system to obtain and process data indicative of muscle reflexes for screening and/or diagnosing a patient with a brain injury or spinal cord injury, and especially for obtaining and processing data indicative of reflexes from the bulbospongiosus muscle. Certain embodiments employ a novel electromechanical probe for stimulating the bulbospongiosus muscle to identify a time of the stimulation so that electrical responses from electrodes on the patient's skin can be identified for analysis.
