摘要： The present invention relates to a system, method and corresponding computer program for milk ejection reflex (MER) determination, the system comprising a breast shield arrangement (1) for a breast pump (2) configured to be attached on a first breast of a female, a physiological sensor unit (4) for receiving a physiological reception signal from the second breast, which is opposite to the first breast, wherein the physiological reception signal is indicative of fluid contents in the second breast, and wherein the system is configured to determine a milk ejection reflex based on a change in fluid contents in the second breast. It finds particular application during and in connection with breastfeeding and allows for direct detection of the beginning of the milk flow in the breast, i.e. the occurrence of the MER, without delay and with a high degree of precision.

摘要： A core body temperature sensor (10) includes a thermoresistant structure (12) having a proximal surface (11) configured for attachment to skin of an associated patient, and a distal end (13) opposite from the proximal surface. A plurality of temperature sensors (14) is arranged to measure temperatures of the thermoresistant structure at a corresponding plurality of different distances from the proximal surface of the thermoresistant structure. A temperature-changing element (16) is configured to change a temperature of the distal end of the thermoresistant structure. An electronic processor (20) is programmed to acquire temperature measurements from the plurality of temperature sensors while operating the temperature-changing element to maintain a temperature of the distal end of the thermoresistant structure at a temperature different from an ambient temperature, and extrapolate a core body temperature of the associated patient from the acquired temperature measurements.

摘要： A first responder network is a network that is used by first responders for communicating between devices typically used by first responding officers. An MCI describes an incident in which emergency medical services are overwhelmed by the number and severity of casualties. A wireless communication system for first responder networks is proposed that can securely register (onboard) a variety of wireless devices to ensure a quicker response time in the MCI area. Existing wireless devices belonging to both triage officers and casualties in the MCI area can automatically be registered to a first responder network to enhance coverage in the MCI area. Expansion of a wireless infrastructure of the first responder network can be enabled by securely registering alien central nodes (e.g., base stations) on an on-demand basis.

摘要： A wearable device may take a set of health inputs from embedded body sensors for the duration of an activity performed by a user of the wearable device. Based on these inputs, the wearable device can calculate a health parameter (e.g., calories burned during the activity). The wearable device can also track its location during the activity, and provide this location to a geolocation data network. The geolocation data network may provide geolocation data (e.g., weather/environmental/terrain data) pertaining to the wearable device's location. The wearable device can then modify its measurements and/or calculated health parameters based on the geolocation data (e.g. Increasing calories burned during a run due to high heat and uphill terrain in the location of the run).
