Abstract: The present disclosure pertains generally to thermostats that are adapted to assist utilities in communicating with its customers. In particular, the present disclosure relates to a thermostat having a display, a controller and a receiver that is coupled to the controller. The receiver is adapted to receive messages from a utility, and the controller is adapted to display one or more related display messages on the display.

Abstract: The present disclosure pertains to thermostats that assist users in monitoring and/or controlling their utility consumption habits and patterns. In particular, the present disclosure relates to a thermostat that includes a housing and a controller located within the housing. The controller may be adapted to implement a control algorithm that permits the controller to operate one or more components of an HVAC system. The thermostat may include a display and a receiver that is configured to receive messages from a utility. In some cases, the controller may provide, on the display, an indication of a measure of utility usage during a first time period (e.g. during a current month) and an indication of a measure of utility usage during a second time period (e.g. during the same month one year ago) that may be after the first time period.

Abstract: The disclosure pertains to thermostats having an improved interface. In some cases, the present disclosure relates to thermostats that can display not only menu items, temperature set points and the like, but also has an ability to display variable textual information that is not predefined at the time of manufacture of the display. The thermostat may include an LCD display that is viewable from outside of the thermostat housing and that includes a first region and a second region. The first display region may include an array of fixed segment pixels that are arranged into a plurality of rows and a plurality of columns for displaying text in a dot matrix format. In some cases, the first region may be adapted to display messages, including scrolling messages. The second region may include a plurality of fixed segment graphical icons, which may be more precisely and more clearly displayed than if displayed using the array of fixed segment pixels of the first region.

Abstract: A digital signal representative of a difference in pressure is received from a differential pressure transmitter. A noise signal is obtained by processing the signal through a band pass filter or otherwise to provide a filtered noise signal. Absolute values of the filtered noise signal are calculated and compared to one or more predetermined threshold values to determine if one or more impulse lines are plugged. A training mode is used to determine the thresholds, which may be a function of flow rate and other flow conditions.

Abstract: A log file is generated from data supplied by cards readers that are part of an access control system and that read access control cards in connection with restricted areas. Probabilities of card holders entering the restricted areas are computed based on the data in the log file. Unusual access patterns are detected from the data in the log file based on the computed probabilities. Group associations between card holders are detected based on common movement of the card holders in connection with the restricted areas. A new log file is created based on those of the detected unusual access patterns that are not associated with the group associations.

Abstract: Air quality within a building is controlled by maintaining a count of people in the building and by ventilating the building with an amount of air dependent on the count. The count may be determined in accordance with an access control system and/or entry and exit sensors, such as infrared sensors.
