An apparatus for estimating bio-information is provided. The apparatus for estimating bio-information may include a pulse wave sensor configured to measure a pulse wave signal from an object; a force sensor configured to measure a first force exerted between the object and the pulse wave sensor; and a processor configured to: convert the first force into a second force, based on structure information of the object; and estimate the bio-information, based on the pulse wave signal and the second force.

Methods and apparatuses, including devices and systems, for remote and detection and/or diagnosis of acute myocardial infarction (AMI). In particular, described herein are handheld and adhesive devices having an electrode configuration capable of recording three orthogonal ECG lead signals in an orientation-specific manner, and transmitting these signals to a processor. The processor may be remote or local, and it may automatically or semi-automatically detect AMI, atrial fibrillation or other heart disorders based on the analyses of the deviation of the recorded 3 cardiac signals with respect to previously stored baseline recordings.

A system and method is presented for cuff-less blood pressure measurement in a mobile device. A key aspect of this disclosure is the discovery of a new location for blood pressure measurement at the fingertip of a subject and that reflectance-mode photoplethysmography can be used to help make this measurement. Through experiments in human subjects, it was discovered that it is indeed possible to measure systemic blood pressure by having a subject press the fingertip against a reflectance-mode photo-plethysmography-force sensor unit under visual guidance and then compute blood pressure from the resulting variable-amplitude blood volume oscillations and applied pressure via an oscillometric algorithm.

A motion state evaluation system is provided with a motion analyzer obtains a value representing a motion state of the subject based on a ratio, to a reference length, of a distance between predetermined joints estimated on an image; a reference storage stores a height of a subject as the reference length; a motion analyzer obtains, as a value for use in evaluation of motion of the subject, the value representing the motion state of the subject from a feature point distance on the image of a plurality of anatomical feature points based on a ratio, to the height, of a distance on the image that is determined from the plurality of anatomical feature points and corresponds to the height of the subject; and an evaluation processor evaluates the motion of the subject based on the value representing the motion state.

An apparatus for and a method for estimating blood pressure are provided. The apparatus for estimating blood pressure includes: a sensor configured to measure a pulse wave signal from an object; and a processor configured to obtain a mean arterial pressure (MAP) based on the pulse wave signal, configured to classify a phase of the obtained MAP according to at least one classification criterion, and to obtain a systolic blood pressure (SBP) by using an estimation model corresponding to the classified phase of the MAP among estimation models corresponding to respective phases of the MAP.

The present disclosure relates generally to instantaneous communication network systems and methods and, in particular, in one or more embodiments, the present disclosure relates to a first multi-mode and multi-frequency communication device capable of connecting directly with a proximate second first multi-mode and multi-frequency communication device. A display screen on the communication device is capable of displaying icons and avatars over a map to show other communication devices which are proximate.

A system that detects and reduces impaired driving includes a first sensor that detects information indicative of a sleep pattern of a user, and a second sensor that detect vehicle operation information. The system also include a mobile electronic device communicatively coupled to the first sensor and the second sensor. The mobile electronic device includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to determine that the user is impaired based on the information indicative of the sleep pattern of the user, and determine that a vehicle is in operation based on the vehicle operation information. The instructions also cause the processor to perform an action to reduce impaired driving in response to determining that the user is impaired and that the vehicle is in operation.

An ingestible device is disclosed which can produce spectral data of one or more analytes, as well as associated methods for characterizing the gastrointestinal tract of a subject which contains such analytes. Related kits and systems are also disclosed.

A system obtains a maternal electrocardiogram (ECG) signal that represents an ECG of a pregnant mother during a first time interval. The system further obtains a mixed maternal-fetal ECG signal that represents a combined ECG of the mother and her fetus during the first time interval; processes the maternal ECG signal and the mixed maternal-fetal ECG signal to generate a fetal ECG signal that represents the ECG of the fetus during the time interval, the fetal ECG signal substantially excluding the maternal ECG signal; and provides an output based on the fetal ECG signal.
