Food thermometer and method of using thereof
First Claim
1. A food thermometer for measuring a temperature of a food exposed to heat, the food thermometer comprising:
- a first portion including electronic components that are sensitive to heat, the first portion configured to be positioned in the food;
a second portion connected to the first portion, wherein at least the first portion or the second portion includes a thermal sensor for detecting the temperature of the food;
a third portion connected to the second portion, the third portion including an antenna for wirelessly transmitting data based on the detected temperature of the food;
an outer shell extending from the second portion to the third portion; and
an inner shell inside the outer shell and extending from the second portion into the third portion, wherein the inner shell with the outer shell in the second portion serve as a coaxial transmission waveguide for an antenna signal, and wherein the inner shell in the third portion serves as at least part of the antenna.

Abstract
A food thermometer includes a first portion for insertion into food. The first portion includes electronics sensitive to heat, and a third portion of the thermometer includes an antenna for transmitting data. According to one aspect, a completion time is estimated based on an ambient temperature and a rate at which the food temperature changes. According to another aspect, the thermometer includes an outer shell with a metallic portion and a non-metallic portion. An inner shell inside the outer shell extends from the metallic portion into the non-metallic portion such that the inner shell in the non-metallic portion serves as at least part of the antenna. The inner shell with the metallic portion of the outer shell serves as a coaxial transmission waveguide for an antenna signal.

18. A food thermometer for measuring a temperature of a food exposed to heat, the food thermometer comprising:
-
a first portion including electronic components that are sensitive to heat, the first portion configured to be positioned in the food; a second portion connected to the first portion, wherein at least the first portion or the second portion includes a thermal sensor for detecting the temperature of the food; a third portion connected to the second portion, the third portion including an antenna for wirelessly transmitting data based on the detected temperature of the food; a charging contact located in the third portion for charging the food thermometer, wherein the charging contact is in electrical communication with the antenna so that the antenna is configured to carry a charging signal from the charging contact; and filter components configured to separate the charging signal from a Radio Frequency (RF) signal for the antenna. - View Dependent Claims (19)
