Abstract: An electronic device is disclosed. The electronic device identifies a user on the basis of: a biological signal input unit for receiving the input of a user's biological signal detected through an electrode; a voice input unit for receiving the input of a voice signal; a biological signal inputted through the biological signal input unit; and a voice signal inputted through a microphone.
Abstract: A neuromodulator includes one or more coil sets. Each of the coil sets has three coils aligned to produce magnetic and electric fields in three different directions. A plurality of conductors couple the coils of the one or more coil sets to one or more input signals such that each of the coils is independently activated via an individually selectable current applied through the conductors. The individual activation creates a resultant field that is a combination of the magnetic and electric fields in three different directions for each of the coil sets.

Abstract: Systems and methods for reducing vibrations perceived by a human due to an artificial heart valve include a vest that is wearable around a torso of the human, a plurality of sensors mounted to the vest, a plurality of vibration-generating actuators mounted to the vest, and a controller. The plurality of sensors detects vibrations in the human generated by the artificial heart valve. The controller is operable to receive signals representing the detected vibrations from the plurality of sensors, and is operable to produce anti-vibration signals that substantially attenuate the detected vibrations. A first sensor of the plurality of sensors is located near a first vibration-generating actuator of the plurality of vibration-generating actuators to form a sensor/actuator set. In the sensor/actuator set, the anti-vibration signals generated by the controller for the first vibration-generating actuator correspond to the vibrations detected by the first sensor.

Abstract: A medical implant system for implantation in a patient to treat erectile dysfunction includes a first fluid path, an inflatable penile prosthesis cylinder, an electric pump, and implant controller, and an implantable power supply. The inflatable penile prosthesis cylinder is in fluid communication with the first fluid path and is configured for implantation in a corpus cavernosum of a patient. The electric pump is in fluid communication with the first fluid path. The implant controller is electrically coupled to the pump and is configured to activate the pump to drive a flow of fluid through the first fluid path and into the cylinder. The implantable power supply provides electrical power to the pump.
Abstract: Devices, systems, and methods for treating a heart of a patient may make use of structures which limit a size of a chamber of the heart, such as by deploying one or more tensile member to bring a wall of the heart and a septum of the heart into contact. A plurality of tension members may help exclude scar tissue and provide a more effective remaining ventricle chamber. The implant may be deployed during beating of the heart, often in a minimally invasive or less-invasive manner. Trauma to the tissues of the heart may be inhibited by selectively approximating tissues while a pressure within the heart is temporarily reduced. Three-dimensional implant locating devices and systems facilitate beneficial heart chamber volumetric shape remodeling.

Abstract: The concentration of substance in blood is measured non-invasively, with high accuracy and with simple configuration. Laser light generated by a light source is locally irradiated on the body epithelium of a subject, and the resulting diffused reflected light is detected by a light detector. The laser light has a wavelength of 9.26 ?m. The laser light is generated by converting and amplifying pulsed excitation light from an excitation light source to a long wavelength. A plate-shaped window that is transparent to mid-infrared light is brought in close contact with the body epithelium. The glucose concentration in interstitial fluid can be calculated using normalized light intensity calculated from a signal ratio of signals from a monitoring light detector and the light detector.

Abstract: A central nervous magnetic stimulation device and a healthcare or medical instrument, wherein the device comprises a power source, a control circuit and a coil component, the control circuit comprising a main control chip and a main circuit, the power source supplying power to the control circuit, and the control circuit outputting a time-varying current to the coil component to generate a corresponding time-varying magnetic field. The area of the time-varying magnetic field matches with the size of a head, and the time-varying current is output at a frequency above 2000 Hz, and constitutes a string of rhythmic cluster-like bursts at an appropriate duty ratio or forms an envelope in a difference frequency way to output rhythm characteristics. The device can apply to the brain a magnetic stimulation with a weak intensity and high-frequency carrier wave, rhythmic cluster-like bursts and an approximately uniform magnetic field intensity distribution.
Abstract: Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

Abstract: A method of modulating a brain activity of a mammal is achieved by subjecting the mammal to repetitive transcranial magnetic stimulation (rTMS) with an rTMS apparatus at variable pulse intervals for a time sufficient to modulate said brain activity. Improvement in a physiological condition or a clinical condition is achieved. Conditions to be treated include but are not limited to PTSD, autism spectrum disorder and Alzheimer's disease. Wavelet transform analysis is used to determine the variable pulse intervals employed.
Abstract: Systems and methods for reducing blood viscosity along a flow direction, suppressing turbulence in blood flow, and treating rouleaux are disclosed. One method includes applying a unidirectional magnetic field to a flow of blood in a direction parallel or antiparallel to a direction of the flow of blood, and maintaining the application of the unidirectional magnetic field to the flow of blood until a blood viscosity along the direction of the flow of blood is reduced and/or the turbulence in the blood flow is suppressed. One system includes an annular magnet sized to encircle a portion of a patient's body. The magnet is adapted to generate a unidirectional magnetic field in a region within the annular magnet. The unidirectional magnetic field has a strength sufficient to reduce the blood viscosity in the portion of the patient's body and/or suppress turbulence in the blood flow by a predetermined amount. The system will also break rouleaux for patients with rouleaux, but the process will take more time.
