A method for commissioning a wireless lighting control system for network connectivity does not require special device network configuration steps during manufacturing. Network configuration happens dynamically and automatically during commissioning of a lighting control group. The method includes receiving at a mobile device an advertisement packet from each of a plurality of lighting control devices via a commissioning network. A commissioning network connection is established with each of the lighting control devices and the mobile device. A lighting control group network table listing an entry for each of the lighting control devices is built to establish the lighting control group that communicates over a lighting control network. The lighting control group network table is sent to a last lighting control device configured by the mobile device via the commissioning network. Receipt of the lighting control group network table readies the device to receive lighting control event messages for the group.

Protocol for out of band commissioning of lighting network element

A networked lighting control system includes a variety of lighting control devices, including intelligent luminaires, standalone intelligent control nodes, plug load controllers, and power packs that communicate over a wireless control network and a commissioning network. Each lighting control device includes a dual-band wireless radio communication interface system. The dual-band wireless radio communication interface system is configured for unicast and multicast communication over a first of two different wireless communication bands as well as point-to-point communication over a second wireless communication band. The standalone intelligence control node can be a wall switch or detector. Commissioning and provisioning of the lighting control system is performed over the second communication band via communications with a mobile device and lighting controls are carried out over the first communication band. The lighting control devices may be divided into light control groups or zones.

Wireless lighting control system

A monitor lighting control device receives a state change event message that includes a payload specifying: (i) a state change event of an occupancy, audio, or daylight sensor, or a switch to turn lighting on/off, dim up/down, set scene or the like; (ii) an identifier of a member lighting control device that detected the state change event; and (iii) a lighting control group identifier of a lighting control group that includes the member lighting control device and the monitor lighting control device. The monitor lighting control device transmits an acknowledgement of receipt of the state change event message to the member lighting control device. The monitor lighting control device generates a state change multicast message that includes the state change event of the payload. Also, the monitor lighting control device transmits the generated state change multicast message to the lighting control group.

Protocol for lighting control via a wireless network

A method of reading a plurality of bar codes during a scanning motion across a bar code scanner which enhances scanner operation. The method includes the steps of obtaining data from a detector in the bar code scanner, determining position information associated with the data, distinguishing data associated with each bar code using the position information, and assembling the bar codes from the data.

Method of reading a plurality of bar codes during a scanning motion

A circuit and method for adjusting the sensitivity of a sensor like a phototransistor which is coupled to an Infrared Emitting Diode (IRED). A controller places input data on a counter to vary the duty cycle of the counter and a low pass filter is used to obtain a DC voltage which varies linearly according to the input data placed on the counter. An amplifier uses the DC voltage to control the current passing through the IRED. The controller changes the input data until the output from the phototransistor reaches a predetermined level. A switchable load is added or switched into the circuit to obtain an additional range of DC voltages to be applied to the IRED when the phototransistor is one which does not generate a high output.

Circuit for adjusting the sensitivity of a sensor using a digital

A method and apparatus for sensing the presence of a document moved to a printing station in a printer and for detecting skewness (if any) of the document at the printing station. A first light-detector pair and a second light-detector pair are used, with the sensitivity of each of the detectors in the light-detector pairs being adjusted each time the printer is turned on. A controller and a stored program are used to adjust the sensitivity of the detector along with a resistor network providing steps of resistance. The particular resistance step to which a detector is adjusted also gives a measure of the useful life left for the detector.
