Abstract: A device and system for monitoring food is described. The food monitoring device has a temperature sensor and a temperature sensor base. The temperature sensor base has a transmitter and a microphone. The temperature sensor base is electrically coupled to the temperature sensor. A monitor having a speaker and a receiver communicates with the transmitter of the temperature sensor base. The transmitter of the temperature sensor base transmits a temperature sensed by the temperature sensor and an audio signal produced by the microphone.

Abstract: A travel pillow has one or more air filters and a body with a soft material coupled to the one or more air filters. The air filters can be powered by a power source located within the pillow. The one or more air filters can have an air intake and an air outflow in communication with an exterior surface of the body. The air filters may be an electrostatic precipitator filter or use a filtering material to clean the air.

Abstract: A pressure gauge for determining air pressure of an inflatable item and a method of doing the same are provided. Embodiments of the present invention provide a source of light capable of providing more than one color of light, where each color of light within the more than one color of light corresponds to a numerical relationship between a determined pressure of an inflatable item, determined by the pressure gauge, and a target air pressure. The pressure gauge also has a display panel for displaying the determined air pressure and at least one of the provided colors of light. In addition, the pressure gauge has a pressure sensor for determining the determined air pressure and a computer defining functions performed by the pressure gauge, wherein the computer causes the source of light to display the different colors of light in accordance with the numerical relationship between the determined air pressure and the target air pressure.
