17 Oct 2011TL;DR: In this paper, the authors proposed an energy conserving communications for networked thermostats powered in part by batteries, where the battery level associated with the battery on the thermostat is at a low battery-level.
Abstract: Aspects of the present invention provide energy conserving communications for networked thermostats powered, in part, by batteries. A thermostat communication server stores a thermostat battery-level to determine what data should be sent to the thermostat. The thermostat communication server classifies types of data to be transmitted to the thermostat according to a data priority ranging from a low-priority to a high-priority data type. If the battery-level associated with the battery on the thermostat is at a low battery-level, the thermostat communication server may only transmit data classified under a high-priority data type. This conserves the power used by the thermostat, allows the battery on the thermostat time to recharge and perform other functions. If the battery-level of the thermostat is at a high level, the thermostat communication server may transmit a range of data to the thermostat classified from a low-priority type to a high-priority data type.

TL;DR: In this paper, a linear driver and a switching regulator are used for regulating an output based on a control signal, where the linear driver has a first input for receiving the control signal and a second input connected to the output for receiving negative feedback.
Abstract: A highly efficient, high control bandwidth and high-speed power supply with a linear driver and a switching regulator for regulating an output based on a control signal. The linear driver has a first input for receiving the control signal and a second input connected to the output for receiving negative feedback. The driver's output is controlled by its two inputs and has a capacitor connected in series with it to generate a capacitor voltage V C responsive to the DC and low frequency components in the driver's output. The switching regulator has a control input and a regulator output connected in a regulator feedback loop. The control input receives capacitor voltage V C and the regulator feedback loop minimizes capacitor voltage V C . Thus, switching regulator takes over the generation of DC and low frequency components, while the linear driver provides high frequency output current components.
