  • Patent number: 8704672
    Abstract: Methods and systems for indicating a status of an air filter of an HVAC system may include receiving a measure that is related to an amount of flow restriction presented by the air filter in an HVAC system, using the measure to determine whether the air filter does not need replacing, the air filter needs to be replaced soon, or the air filter should be replaced now, and displaying on a display of an HVAC controller an air filter status indicator, wherein the air filter status indicator includes a stop-light metaphor. In one example, the air filter status indicator may display a green color when the air filter does not need replacing, display a yellow color when the air filter needs to be replaced soon, and display a red color when the air filter should be replaced now. In some cases, the air filter status indicator may also include a qualitative term indicative of the current status of the air filter.

  • Patent number: 7855658
    Abstract: Provided is a method for controlling light, including retrieving accelerations along an X-axis, a Y-axis, and a Z-axis with a 3-axis accelerometer sensor; matching the retrieved accelerations with RGB values; and transforming the RGB values and displaying a color of the transformed RGB values. The 3-axis accelerometer sensor retrieves the accelerations Ax, Ay, and Az along the X-axis, the Y-axis, and the Z-axis and calculates a velocity Vi along the X-axis, the Y-axis, and the Z-axis using the accelerations Ax, Ay, and Az, with i denoting directions x, y, and z, Vi=Vio+Ait expressing a terminal velocity in the direction i, Vio denoting an initial velocity in the direction i, Ai denoting the acceleration in the direction i, and t denoting time, thereby allowing variation of brightness to be controlled in eight modes.
