The electrocardiographic measurement apparatus includes: a plurality of electrodes that has a length along a circumferential direction of an upper arm, the length being variable in accordance with a length in the circumferential direction of the upper arm, and detects an electric potential from the upper arm that is brought into contact with the electrodes; and a device body that generates electrocardiographic information based on the electric potential detected by the plurality of electrodes.

A belt used in an electrocardiographic measurement apparatus includes a belt body to be wrapped around a living body, three or more base electrodes disposed in a longitudinal direction of the belt body, and two or more cap electrodes detachable and attachable to the base electrodes and smaller in number than the number of base electrodes.

A blood pressure monitor configured to removably mount to a cuff in a substantially symmetrical position with respect to a width of the cuff can include a housing defining an interior, a first port, and a second port. The first port can: secure to a first prong of the cuff when the cuff is mounted in a first orientation; receive and secure to a second prong of the cuff when the cuff is mounted in a second orientation; and enable fluid communication between the interior and at least one of a first fluid passage within the first prong and a second fluid passage within the second prong. The second port can: secure to the second prong of the cuff when the cuff is mounted in the first orientation; and receive and secure to the first prong of the cuff when the cuff is mounted in the second orientation.

A vitals monitoring handcuff apparatus comprising a housing structure that is adapted to be coupled with a set of handcuffs and to contain a plurality of modules and units; a first module that is located within the housing structure and adapted to measure a wearer's heartrate via a sensor; a second module that is located within the housing structure and is adapted to measure the wearer's respiration rate via a sensor; a controller unit that is located within the housing structure, is configured to relay instructional programs to the modules and units which causes the modules and units to operate, and the controller unit receives data from the modules and inputs that data into associated algorithms that produce corresponding output signals; a communication unit that is located within the housing structure and receives the output signals from the controller unit and is adapted to relay the output signals to a user; and a rechargeable power unit located within the housing structure that is accessed by a port on an exterior of the housing structure, provides power to the vitals monitoring handcuff apparatus's other modules and units, and having a receiver which connects with an exterior power source via the port.

A system comprising a plurality of neuromuscular sensors, each of which is configured to record a time-series of neuromuscular signals from a surface of a user's body; and at least one computer hardware processor programmed to perform: applying a source separation technique to the time series of neuromuscular signals recorded by the plurality of neuromuscular sensors to obtain a plurality of neuromuscular source signals and corresponding mixing information; providing features, obtained from the plurality of neuromuscular source signals and/or the corresponding mixing information, as input to a trained statistical classifier and obtaining corresponding output; and identifying, based on the output of the trained statistical classifier, and for each of one or more of the plurality of neuromuscular source signals, an associated set of one or more biological structures.

A monitoring system a user activity sensor to determine patterns of activity based upon the user activity occurring over time.

Disclosed is a device for transdermally detecting the concentration of one or more substances in a subject's bloodstream. The device includes a signal generation module arranged to generate microwave frequency signals at one or more discrete frequencies. The device also includes a sensor module comprising at least one microwave resonance sensor arranged to make contact with a subject's skin, the at least one microwave resonance sensor arranged to transmit microwave frequency signals generated by the signal generation module into the subject's body. The device also includes a signal processing module connected to the at least one microwave resonance sensor and arranged to: detect a resonance characteristic of the at least one microwave resonance sensor, and process the resonance characteristic to determine the concentration of one or more substances in a subject's bloodstream.

A blood pressure monitor of the present invention includes a cuff to be wrapped around a measurement site. The blood pressure monitor includes a unit including, as elements for blood pressure measurement, a pump, a valve, a pressure sensor, and an inner pipe connecting the pump, valve, and pressure sensor such that fluid can pass therethrough. The blood pressure monitor includes a connecting pipe connecting the cuff and the inner pipe in the unit such that fluid can pass therethrough. The blood pressure monitor includes a self failure diagnosis unit configured to determine whether or not there is a failure in a fluid system including the pump, the valve, the pressure sensor, the inner pipe, the connecting pipe, and the cuff, in a state in which the cuff is empty-wrapped into a cylindrical shape and the capacity of the cuff is restricted.
