Embodiments of the present disclosure provide techniques and configurations for an apparatus for opportunistic measurements of a user's physiological context, such as evaporation rate. In one instance, an apparatus may include a chamber with a first side and a second side opposite the first side. The chamber may be disposed with the first side in proximity to or in contact with a surface (e.g., body of the user). The first side may include a first opening to allow evaporation from the surface to enter the chamber. The chamber may include a second opening to allow the evaporation to exit the chamber. The chamber may further include first and second sensors (e.g., humidity sensors) disposed inside the chamber, to detect the evaporation from the surface. The apparatus may be configured to measure the evaporation based on evaporation readings provided by the sensors. Other embodiments may be described and/or claimed.

Embodiments of the present invention may provide a system with a first and second circuit system separated by an electrical isolation barrier but provided in communication by at least one isolator device that bridges the isolation barrier. The first circuit system may include a communication system to transmit data across a common isolator device as a series of pulses, and the second circuit system may receive the series of pulses corresponding to the data. The second circuit system may include a detector coupled to the common isolator device to detect the received pulses, a oneshot to frame the received pulse(s), and a controller to reconstruct the data based on accumulated framed pulse(s). Therefore, noise induced spurious pulses outside the oneshot intervals may be ignored by the second circuit system providing improved noise immunity.

According to an embodiment of the present invention, a system comprises a removable interface module and wireless dock for an automated external defibrillator. The removable interface module includes a first processor, a first memory and first low-power radio transceiver communicatively coupled with the first processor and configured to receive status information from the automated external defibrillator. The removable interface module further includes a wireless power receiver and a rechargeable energy storage device electrically coupled with the wireless power receiver and configured to receive power wirelessly for the removable interface module. The wireless dock includes a second processor, a second memory and second low-power radio transceiver communicatively coupled with the second processor and configured to receive the status information from the removable interface module when the automated external defibrillator is powered off and transmit the status information through a networking interface. The wireless dock further comprises a wireless power transmitter.

A health-monitoring system and method are disclosed. The health-monitoring system and method comprise a sensory system and a sensory to front-end communication (SFCM) protocol coupled to the sensory system. The health-monitoring system and method include a front-end system coupled to the sensory system and a front-end to back-end communication (FBCM) protocol coupled to the front-end system. The health-monitoring system and method include a back-end system. The SFCM protocol communicates with the front-end system using a first state awareness link and the FBCM protocol communicates with the back-end system using a second state awareness link.

When it is determined that a position of the display terminal is within a range of a prescribed distance from the house and when it is determined that the log information and the information indicating the operational state of the one electric home appliance are not consistent with each other, the server provides the display terminal with information on a possibility of a malfunction of the one electric home appliance while the position of the display terminal is still within the range of the prescribed distance from the house.

The embodiments of the disclosure provide a method and device for joining network processing of a sensor, network platform equipment and an Internet of things gateway. Wherein, the method includes that: a joining network request message used for requesting to perform joining network on the sensor is received, wherein the joining network request message contains Identity, ID, information of the sensor; a joining network state of the sensor is determined according to the ID information; and the determined joining network state is sent to an Internet of things gateway, wherein the joining network state is used for executing joining network processing on the sensor by the Internet of things gateway.

The present disclosure relates to diagnosing and locating fluid leakage within a pneumatic system (5) using a minimal amount of pressure sensors (55, 75, 89). In general, each branch (51, 71, 85) of a pneumatic system (5) includes an associated pressure sensor (55, 75, 89) and in accordance with how the pneumatic components (57, 59, 61, 77, 91, 93, 95) associated with the pneumatic branch (51, 71, 85) are toggled and monitored, leaks can be detected and located within the branch (51, 71, 85) using a minimal amount of pressure sensors (55, 75, 89). More specifically, pressure and pressure decay may be measured by the sensors (55, 75, 89) within a branch (51, 71, 85) while the pneumatic components (57, 59, 61, 77, 91, 93, 95) are in a particular configuration. The configuration is thereafter changed, and pressure and pressure decay are again measured by the sensors (55, 75, 89). The results of these two measurements may enable the pneumatic system (5) to derive the presence and location of a leak.

An appliance network connectivity apparatus includes a voltage sensor that generates a signal at an output that is proportional to a voltage provided to the appliance. A current sensor generates a signal at an output that is proportional to a current flowing through the appliance. A processor determines the electrical characteristics of power consumed by the appliance and executes web server software for communicating data through a network. A relay controls power from the power source to the appliance. A memory stores the electrical characteristics. A network interface provides the electrical characteristics to the network.

An exercise feedback system calibrates sensors of an athletic garment worn by an athlete while performing exercises. The sensors can record physiological data such as muscle activation. The system instructs the athlete to perform a calibration workout. The system generates a calibration value based on physiological data from the calibration workout and/or user information. The calibration value indicates, for example, the predicted maximum amplitude for the muscle activation of a particular muscle group (for example, glutes, hamstrings, or quadriceps) of the athlete. The system can update the calibration value over time as the system receives additional physiological data from subsequent exercises performed by the athlete. The system may determine a confidence level of the calibration value and may update the calibration value if the confidence level becomes too low. The system provides biofeedback to the athlete generated based on the calibration value.

Disclosed systems and methods include electronic devices attached to a patient or object that transmit data to other devices over a secure communication channel. The devices can track and/or monitor object(s) and/or patient(s) and transmit the tracked and/or monitored data to other electronic devices. Such data can include monitored patient physiological parameter(s) received and/or sensed by the device, for example. A master of the two devices transmits a communication signal to another device that, in response, initiates a secure wireless communication channel, causes one or more modules on the device to be powered, and, when powered, transmits the tracked and/or sensed physiological data over the secure wireless communication channel to the master device. Some example master devices transmit the communication signal with an instruction to the device to activate an onboard power source that later may be disconnected after the tracked and/or physiological data is transmitted.
