According to an embodiment of an aspect, there is provided a computer-implemented method for determining a sleep state of a user. The method comprising receiving (S11) a physiological signal from a physiological signal detector used by the user. The method further comprising determining (S12), based on the received physiological signal, the sleep state of the user. The method further comprising calculating (S13) a reliability value associated with the determination. The reliability value being calculated based on a comparison of the received physiological signal with historic physiological signals of the same sleep state as the determined sleep state. There is further provided a device (20) and computer-readable medium (30). In accordance with the present disclosure, the sleep state of a user may be determined with greater accuracy when compared with past methods.

Some disclosed methods involve controlling, via a control system, a light source system to emit a plurality of light pulses into biological tissue at a pulse repetition frequency, the biological tissue including blood and blood vessels at depths within the biological tissue. Such methods may involve receiving, by the control system, signals from the piezoelectric receiver corresponding to acoustic waves emitted from portions of the biological tissue, the acoustic waves corresponding to photoacoustic emissions from the blood and the blood vessels caused by the plurality of light pulses. Such methods may involve detecting, by the control system, heart rate waveforms in the signals, determining, by the control system, a first subset of detected heart rate waveforms corresponding to vein heart rate waveforms and determining, by the control system, a second subset of detected heart rate waveforms corresponding to artery heart rate waveforms.

The present invention relates to device, system and method for determining a priority level and/or conversation duration of a call. An improved and adaptive device comprises a signal input (31) for obtaining an image data signal (21) of a user initiating a call, a physiological data extraction unit (32) for extracting physiological data (22) of the user from the obtained image data signal (21), a health condition determination unit (33) for determining the health condition (23) of the user based on the extracted physiological data, and a prioritization unit (34) for determining the priority level and/or conversation duration (24) of the call based on the determined health condition of the user.

A system is provided to provide triage recommendations for animals. The system accesses a syndrome mapping of syndromes to complaints, each syndrome having a triage category. The system accesses a complaint mapping of complaints to symptoms. Each symptom for a complaint has a weight. The system receives indications of a current complaint and current symptoms of an animal. Each current symptom has a score. The system identifies the triage category based on a syndrome to which the current complaint and the current symptoms apply, factoring in the weights and the scores. The system provides a recommendation for the animal based on the identified triage category.

A device for delivering medication to a user may include a main body, an electronics module, and a slider. The main body may include a mouthpiece, a medication reservoir, and a mouthpiece cover, where the mouthpiece cover may be hinged to the main body. The electronics module may include a communication circuit, a pressure sensor, and a switch. The slider may be configured to engage the switch when the mouthpiece cover moves from a closed position to an open position. The switch may be configured to switch the electronics module from an off state or a sleep state to an active state. The electronics module may be configured to never return to the off state after the mouthpiece cover is moved to expose the mouthpiece for the first time by the user.

A method includes computing one or more values of at least one parameter at respective times during an exhalation of a subject, based on one or more properties of sound passing through air exhaled by the subject during the exhalation, the parameter being related to a concentration of a gas in the air. The method further includes generating an output in response to the values. Other embodiments are also described.

The objective of the present invention is to provide a hardness meter which estimates hardness in a stable manner regardless of a compression strength. Disclosed is a hardness meter characterized in being provided with: a movable portion which is continuously pressed against an object to be measured; a sensor which outputs an output signal reflecting a reaction force at a part of the object to be measured that is in contact with the movable portion; a motive force mechanism that causes the movable portion to perform a piston motion; and a hardness estimating portion which estimates the hardness of the object to be measured on the basis of an alternating current component of the output signal, generated by the piston motion of the movable portion.

Disclosed herein is an uroflowmeter which includes: a sensor having a signal transmitter transmitting an input signal to a detection area and a signal receiver receiving an echo signal reflected from urine passing through the detection area; a signal processing unit calculating uroflowmetry data based on a difference between the input signal and the echo signal, the uroflowmetry data being data about a flow of the urine passing through the detection area; and a diagnosis unit diagnosing urinary disorders of a test subject by comparing the uroflowmetry data calculated by the signal processing unit with preset reference uroflowmetry data.

Personal diagnostic devices including diagnostic patches (bio-patches) and interactive medical bracelets (bio-bracelets) are provided with a skin/patch interface, at least one analysis layer, a signal processing layer, and a user output interface. Embodiments of the interactive diagnostic devices may include micro-fluidic circuits with reaction chambers, analysis chambers, mixing cambers, and various pre-disposed chemistries or reagents for performing a wide verity of tests by transdermal transport of blood or perspiration. Sample collection chambers for the fluidic circuit may include minimally invasive tubules that penetrate the skin surface to acquire blood samples from capillaries near the epidermis. Alternate implementations of the personal diagnostic device may be equipped with logic processing, input/output devices, acoustic microphones, cryogenic circuits, embedded processors, electrical control circuitry, and battery current sources or photovoltaic sources of electrical power.

A sweat collection device includes a flexible body having a first, outwardly facing surface and a second, skin-facing surface, and a sweat collection channel formed in the body, the sweat collection channel having a first end defining a sweat inlet port, and a second end defining a sweat outlet port. The sweat inlet port and the sweat outlet port are configured to be closed and sealed such that the sweat collection device and the collected sweat therein may be stored and shipped.
