Abstract:
An electronic thermostat is described that includes a head unit, a rotatable ring, a backplate, an electronic display that is viewable by a user in front of the thermostat, a printed circuit board, and a daughter circuit. The daughter circuit is coupled to the printed circuit board, and senses motion of the rotatable ring and includes a first temperature sensor. A second temperature sensor separated from the first temperature sensor, are both used to calculate ambient temperature. The first temperature sensor is positioned at least partially within a cavity formed between a front surface of the head unit and the printed circuit board.

Abstract:
Various methods related to antennas and embodiments of antennas are presented. The antenna may include an upper arm, wherein the upper arm is substantially parallel to a ground plane and is electrically coupled with at least a ground shorting structure, a support structure, and a feed structure. The antenna may include the ground shorting structure, which may be at a first end of the upper arm. The antenna may include the support structure, which may be at a second end of the length of the upper arm and may support the upper arm. The antenna may also include the feed structure, which is configured to provide a signal for wireless transmission, the feed structure may be attached to a side of the length of the upper arm.
Abstract:
According to one embodiment, a thermostat includes a main body, a rotatable input component that is rotatably coupled with the main body, and a rotation detection system that is configured to sense user rotation of the rotatable input component. The rotatable input component is configured to be rotated by a user to enable the user to provide input to the thermostat. The rotation detection system includes a magnetic component that is positioned on an inner surface of the rotatable input component and that is magnetized so as to have a plurality of alternating north and south magnetic regions. The rotation detection system also includes a sensor that is positioned adjacent the magnetic component. The sensor is configured to detect polarity changes as the rotatable input component and magnetic component are rotated relative to the sensor.
