Described herein are assistant robots that anticipate needs of one or more people (or animals). The assistant robots may recognize a current activity, knowledge of the person's routines, and contextual information. As such, the assistant robots can provide or offer to provide appropriate robotic assistance. The assistant robots can learn users' habits or be provided with knowledge regarding humans in its environment. The assistant robots develop a schedule and contextual understanding of the persons' behavior and needs. The assistant robots may interact, understand, and communicate with people before, during, or after providing assistance. The robot can combine gesture, clothing, emotional aspect, time, pose recognition, action recognition, and other observational data to understand people's medical condition, current activity, and future intended activities and intents.

An MEMS airborne ultrasonic transducer system operating on a thermoacoustic principle to determine brain haemorrhage, includes: an RF transmitter and ultrasound receiver systems to transmit RF energy and receive ultrasound wave, respectively, an RF transmitter system having an RF signal generator, an RF amplifier and a horn antenna, and an ultrasound receiver system having a lock-in amplifier, a DC supply and two ultrasonic transducer arrays wirebonded to low noise amplifier (LNA) chips. The MEMS airborne ultrasonic transducer system determines brain haemorrhage based on detecting RF-induced, blood-originating, thermoacoustic ultrasound wave at the pulse modulation frequency.

An excreta identification device includes: a sound data acquisition unit that acquires sound data collected by a microphone arranged in a toilet; an excreta identification unit that identifies which of defecation, urination, and farting has been performed by inputting the acquired sound data to an identification model subjected to machine learning where sound data indicating any of defecation sound, urination sound, and farting sound is an input value, and which of defecation, urination, and farting has been performed is an output value; and an identification result output unit that outputs an identification result.

Provided is a mask apparatus. The mask apparatus includes a mask body in which a microphone and a speaker are installed, a face guard coupled to a rear surface of the rear body so as to be in close contact with a user's face and having a breathing space therein, a pressure sensor installed in the mask body to measure a pressure of the breathing space, and a controller configured to compare a current pressure value measured by the pressure sensor to a reference pressure value and control a voice output of the speaker based on a difference between the current pressure value and the reference pressure value.

Provided is a method for controlling a mask apparatus. The method for controlling the mask apparatus includes measuring a current pressure value with respect to a mask by using a pressure sensor, comparing each of a preset atmospheric pressure maximum estimation and a preset and a preset atmospheric pressure minimum estimation to the current pressure value; updating the atmospheric pressure maximum estimation and the atmospheric pressure minimum estimation according to the comparison result, and controlling a voice output of a speaker based on a difference between the updated atmospheric pressure maximum estimation and the updated atmospheric pressure minimum estimation.

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.

Embodiments of the present disclosure relate to determining an optimal location on the body of a person where heart sounds may be optimally heard. The optimal location may be determined at a time prior to the attempted auscultation and ECG data corresponding to the optimal location may be stored in a memory of an auscultation device. Subsequently, when a e.g., physician wishes to listen to the heart sounds of the person, the physician may place the auscultation device at a first location on the patient. The auscultation device may periodically perform an ECG at a current location and use the ECG data at the current location and the ECG data at the optimal location to determine and provide guidance to the physician regarding a direction in which the auscultation device should be moved in order to reach the optimal location.

A method of determining a fitness level of user with a physiological sensor. The method includes measuring a physiological value of the user with the physiological sensor, correlating the measured physiological value into a measurement of the user's respiratory rate and tidal volume, calculating a second respiratory rate value using the measured tidal volume, calculating a breathing efficiency (BE) ratio based on a comparison of the user's measured respiratory rate and the calculated second respiratory rate value, correlating the calculated BE ratio to a predetermined threshold, and assigning a classification to the user based on the calculated BE ratio. The classification is indicative of the user's respiratory function performance.

A robot according to the present disclosure comprises: a microphone; a camera disposed to face a predetermined direction; and a processor configured to: inactivate driving of the camera and activate driving of the microphone, if a driving mode of the robot is set to a user monitoring mode; acquire a sound signal through the microphone; activate the driving of the camera based on an event estimated from the acquired sound signal; confirm the event from the image acquired through the camera; and control at least one constituent included in the robot to perform an operation based on the confirmed event.

A device for detecting stenosis comprising disposable components to ensure function and sanitary conditions, said device having a disposable sensing pad, a disposable piezo assembly, and a disposable sensing pod; wherein the entire device can be disposed of after a predetermined number of uses to ensure accuracy of results and of sanitary conditions.
