  • Patent number: 11478106
    Abstract: A baby food warming system for warming baby food, including milk and other liquid or semi-liquid beverages, without using an AC power source is disclosed. The present invention provides a system including a charging case and a baby food warmer. The charging case includes an upper cover having a magnet, and a charging base having a magnetic switch, a charging connector, and an UV-C light emitting diode. The baby food warmer includes a main body having a temperature regulator, an external sensor, and an internal sensor, all at a lower tip of the main body, and a top cap attachable to the main body for closing the main body. The top cap further includes a micro-controller configured to generate control signals for controlling the temperature regulator, and to receive sensing signals from the external sensor and the internal sensor.

  • Patent number: 10980371
    Abstract: A conveyor toaster for toasting a customized pattern with multiple levels of brownness on a surface of sliced bread is disclosed. The present invention provides an apparatus including a processor, a moistening chamber; and a heating chamber. The moistening chamber further includes a nozzle for discharging water to the sliced bread; and a sliding track allowing the nozzle to move along. The heating chamber further includes a plurality of heating elements. The processor is configured to control a pump motor for adjusting the amount of water discharged from the nozzle and a movement of the nozzle along the sliding track to coordinates determined according to the customized pattern for positioning the nozzle above a region on the sliced bread, wherein the amount of water discharged over the region is determined according to the coordinates and the customized pattern.

  • Publication number: 20200352451
    Abstract: A body temperature monitoring system for monitoring the body temperature continuously and providing alert in an event of detecting temperature irregularity is disclosed. The monitoring system includes a monitoring pad attachable to the human body for measuring the body temperature at various positions, and transmitting the collected data to the cloud system. The monitoring system further includes a cloud system having a database, and a mobile device having a transceiver, a processor, and a mobile application for configuring the monitoring system and receiving the alert. The database includes a device specific database and a clinical database, which facilitates the processor to identify a temperature irregularity when the measured body temperature is consistently outside an acceptable range of body temperature. The monitoring pad can be attached to the human body at various positions and accurately identify any temperature irregularity.
