Abstract: A method (3600) and system (2800, 2900, 3000, 3100) autonomously create a restore point for a luminaire controller (2810, 3110) and restore it to proper operation when required. The luminaire controller operates by using first operating software having a first software image, and receives a second software image of second operating software. The luminaire controller communicates the first software image to a first device (2820, 3120) connected to the luminaire controller via a communication network (2805, 3105), installs the second operating software, and performs a self test of the luminaire controller. If the luminaire controller fails the self test, the luminaire controller requests via the network that the first device transfer the first software image to the luminaire controller via the network, receives the first software image, installs the first operating software, and reverts to operation with the first operating software.

The tube segment (12) is modular for forming an articulated tube (100) around the conduit through locked interlocking longitudinal interconnection of multiple similar such tube segments (12). The locking of the circumferential interconnection of the elements (1) is ensured both by the manner of interlocking of a tube segment concerned (12) with a tube segment (16) situated on one side thereof, and by the manner of interlocking of the tube segment concerned (12) with a tube segment (14) situated on the other side thereof.

Abstract: A target structure such as an alignment mark on a semiconductor substrate becomes obscured by an opaque layer so that it cannot be located by an alignment sensor. A position for the mark is determined using an edge position sensor and relative position information that defines the position of the mark relative to one or more edge portions of the substrate is stored prior to formation of the opaque layer. A window can be opened in the opaque layer, based on the determined position. After revealing the target structure, the alignment sensor can, if desired, measure more accurately the position of the target structure, for use in controlling a further lithographic step. The edge position sensor may be a camera having an angle-selective behavior. The edge position sensor may be integrated within the alignment sensor hardware.

Abstract: A lighting control module comprises an interface for receiving a dimming setting and a memory for storing the dimming setting. Based on the dimming setting, an output circuit generates a dimming control signal for application to a conventional dimming interface of a lighting driver circuit.

This provides a simple to use way to implement a controllable brightness, which makes use of a dimming driver but used for a luminaire which does not need to be within a networked dimmable system architecture.
