Abstract:
A thermostat for controlling an HVAC system is described, the thermostat having a user interface that is visually pleasing, approachable, and easy to use while also providing intuitive navigation within a menuing system. In a first mode of operation, an electronic display of the thermostat displays a population of tick marks arranged in an arcuate arrangement including a plurality of background tick marks, a setpoint tick mark representing a setpoint temperature, and an ambient temperature tick mark representing an ambient temperature, the setpoint temperature being dynamically changeable according to a tracked rotational input motion of a ring-shaped user interface component of the thermostat. In a second mode, the a plurality of user-selectable menu options is displayed in an arcuate arrangement along a menu option range area, and respective ones of the user-selectable menu options are selectively highlighted according to the tracked rotational input motion of the ring-shaped user interface component.
Abstract:
A thermostat is described for controlling air temperature in a building. The time associated with causing the controlled air temperature to reach a target temperature is estimated and displayed to a user. Input from a user indicating the target temperature can be received and the estimating and displaying can be carried out in real time. The thermostat can be wall-mounted or the user input can be received and estimated time can be displayed using a remote device, for example that communicates wirelessly with other components of the HVAC system.
Abstract:
A method is described for identifying faults relating to an HVAC system, such a clogged filter. Sensor data is used to estimate HVAC system efficiency. Trends in system efficiency are then used to identify faults such as clogged filters. The sensor(s) can include one or more of the following types: optical sensor, temperature sensor, pressure sensor, acoustic transducer, humidity sensor, resistive sensor, capacitive sensor, and infrared sensor. The efficiency estimation can also be based on conditions external to the building, such as data from exterior sensors and/or data gathered from third parties such as government or private weather stations. The efficiency estimation can also be based on performance metrics such as the time used to reach a set point temperature. The fault identification includes filtering out non-fault related events.
Abstract:
A light source package for selectively interrupting power to a light source is provided. An optical element is positioned to reflect a reflected portion of the light from the light source. The reflected portion impinges upon a base that includes a roof panel with a light source side and a sensor side that is opposite to the light source side. The light source side of the roof panel receives the reflected portion of the light and transmits a transmitted portion of the light through the roof panel. The sensor side of the roof panel includes a recess in which a sensing component is located. The sensing component receives the transmitted portion of the light and is configured to interrupt power to the light source when the transmitted portion of the light is below a threshold.
Abstract:
Systems and methods are described for interactively and graphically displaying performance information to a user of an HVAC system controlled by a self-programming network-connected thermostat. The information is made on a remote display device such as a smartphone, tablet computer or other computer, and includes a graphical daily summary each of several days. In response to a user selection of a day, detailed performance information is graphically displayed that can include an indication of HVAC activity on a timeline, the number of hours of HVAC activity, as well as one or more symbols on a timeline indicating setpoint changes, and when a setpoint was changed due to non-occupancy.
Abstract:
Various technologies for delivering contextual television advertisement are described. A user selection of a media title is received. The media title has an associated set of contextual metadata that includes information regarding the media title. A request for the media title is forwarded to a first server and an advertisement request including the set of contextual metadata is forwarded to a second server. The second server uses the set of contextual metadata to retrieve contextual television advertisement information. The contextual television advertisement information and the media title are received from the second server and the first server respectively. Also, the contextual television advertisement information and the media title are played.
Abstract:
A thermostat for controlling an HVAC system is described, the thermostat having a user interface that is visually pleasing, approachable, and easy to use while also providing ready access to, and intuitive navigation within, a menuing system capable of receiving a variety of different types of user settings and/or control parameters. For some embodiments, the thermostat comprises a housing, a ring-shaped user-interface component configured to track a rotational input motion of a user, a processing system configured to identify a setpoint temperature value based on the tracked rotational input motion, and an electronic display coupled to the processing system. An interactive thermostat menuing system is accessible to the user by an inward pressing of the ring-shaped user interface component. User navigation within the interactive thermostat menuing system is achievable by virtue of respective rotational input motions and inward pressings of the ring-shaped user interface component.
