Abstract: The current subject matter describes a delivery of medication to a patient based on a scan of a medication container by a scanner implemented on an infusion system. The medication can include oral medications, injection medications, patches, and/or medication drops. The scanner can scan a machine-readable representation (for example, a barcode) on the medication container to obtain recommended delivery data. A user interface device of the infusion system can display the recommended delivery data on a graphical user interface.

Abstract: Remote control of energy consumption is realized using a readily installable, flexible approach. According to an example embodiment of the present invention, a remote source communicates with a wireless controller for executing energy usage control. The remote source sends signals to the wireless controller via a gateway located near or, in one implementation, forming part of the wireless controller. In response to the signals, the wireless controller sets control settings for operating one or more of a variety of equipment types, such as a furnace, air conditioner, water heater or heat pump. With this approach, wired connections from the gateway to energy-consuming equipment do not necessarily need to be made in order to affect remote energy-consumption control. For instance, when used in connection with a controller wired to the energy-consuming equipment, the gateway need only communicate wirelessly with the controller and does not necessarily need to be coupled to the energy-consuming equipment.
