Abstract: An infant care apparatus includes a piezoelectric sensor and an infrared array sensor. The piezoelectric sensor senses a respiration rate and a heart rate of an infant. The infrared array sensor senses a body temperature and an occupancy state of the infant in a non-contact manner. The abovementioned infant care apparatus can assist in determining an abnormality of the respiration rate and the heart rate of the infant based on the occupancy state of the infant output by the infrared array sensor, so as to reduce a false alarm rate.

Abstract: A temperature sensor device for a power distribution panel includes a Power over Ethernet (PoE) interface, a DC-to-DC step down converter, at least one infrared temperature sensor array, a microcontroller and a communication interface. The PoE interface is used to obtain a required power supply from the Ethernet network. The DC-to-DC step down converter steps down the power supply from a first voltage to a second voltage. The infrared temperature sensor array receives infrared rays radiated from a monitored area of the power distribution panel and generates a corresponding sensation signal. The microcontroller receives the sensation signal and generates an alert signal when the sensed temperature of the monitored area exceeds a preset threshold. The threshold can be dynamically adjusted according to time of day or day of months. The communication interface enables the communication between an external electronic device and the temperature sensor device for the power distribution panel.

Abstract: An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. The conversion from wrist temperature to body core temperature uses detected ambient temperature and fixed humidity or imported humidity level to calculate the body core temperature based on experimental data and curve fitting. The skin temperature compensation can be set differently for different sex gender, different standard deviation of wrist temperature and external relative humidity reading.
