Abstract: A control subsystem, for a utility delivery subsystem having an effector for enabling or disabling delivery of a utility from a source to an output device via a conduit, includes an effector host configured to receive the effector at a port. The effector host operates the effector in response to an instruction received via a wireless communications interface. The subsystem includes a control gateway having a two communications interfaces, a first to establish a connection with the effector host, and a second to connect to a network. The control gateway includes a memory storing schedule data received via the second interface, and a processor configured to send the instruction to the effector host via the first interface, based on the schedule data. The subsystem includes a server having a memory storing the schedule data and a server communications interface for transmitting the schedule data to the control gateway.

Abstract: A power management device for an electrically powered apparatus includes a plurality of cell management circuits and a controller. Each cell management circuit includes a set of terminals to receive one power cell; a boost converter connected to an output of the terminals; and an energy storage component selectively connected to one of an output of the boost converter, for receiving and storing energy from the boost converter, and an output of the cell management circuit, for delivering energy to the apparatus. The controller is configured, for each cell management circuit, to: obtain a cell output level; based on the cell output level, select a boost output level for the boost converter; and alternately connect the energy storage component to the boost converter output to collect energy from the boost converter at the boost output level, and the management circuit output to deliver the energy to the apparatus.
