A system and method to determine a health status of a LED light string. The system () includes a circuit that includes a LED light string () and a pulsed current driver () of the LED light string. The circuit is connected to a power source (). The system includes a current sensor () measuring a current through the circuit. The system includes a detecting device () determining a state of the circuit. The detecting device determines an expected current expected to be passing through the circuit where the expected current is associated with the state. The detecting device receives a current measurement from the current sensor during a time when the circuit is in the state. The detecting device determines a comparison between the current measurement and the expected current. The detecting device generates an output indicative of a health status of the circuit based on the comparison.

A device, system, and method determine addresses of nodes for an arrangement including strings that have nodes and a splitter. The system includes a controller device connected to a first string, the first string also connected to the splitter. The system includes a bus configuration connecting the nodes to one another and to the controller device. The controller device transmits first signals to the nodes of the first string and sequentially receives first responses. The controller device assigns addresses to the nodes of the first string. The controller device generates a second signal that defines a path to a splitter output. The controller device sequentially receives second responses from nodes of a second string on the splitter output and then assigns addresses to the nodes of the second string.

An energy management system for providing sequential application of power to electrical loads contains a series of electrical loads and at least one unit controller, wherein each unit controller connects to at least one electrical load and controls power application to the at least one electrical load. Each individual unit controller has a unique identification to allow for communication with the individual unit controller, wherein each unique identification has a unique power-on delay. The unit controller contains a memory and a processor configured by the memory to: determine if a power-off condition has occurred, being followed by a power-on condition, referred to as a powerup event; and enable delivery of power, after a powerup event, to the at least one electrical load in accordance with the unique power-on delay of the unit controller. A building controller or central server may instead provide sequential application of power.

A data entry device is provided, having as its primary function the entry of numeric data. A secondary function is the entry of alphabetic characters. The device is operated with a single hand and requires no shift or function keys. The number of keys of the device is kept to a minimum to avoid visual clutter and to facilitate its use with one hand. The keys are designed to be easy to access and to be operated while wearing a glove.
