摘要： A system is described. The system includes a control transistor, a voltage source, a feedback node connected between a drain of the control transistor and the voltage source, a plurality of resistors connected between the voltage source and ground, and a control node connected to a gate of the control transistor. The resistors include a first series-connected set of resistors associated with the control transistor being biased and a second series-connected set of resistors associated with the control transistor being unbiased. During a startup period, the control node is configured to bias the control transistor to select the first series-connected set of resistors, thereby increasing a voltage level of the voltage source to a boosted VCC voltage. After the startup period, the control node is configured to unbias the control transistor to select the second series-connected set of resistors, thereby decreasing the boosted VCC voltage to a normal VCC voltage.

摘要： A luminaire which provides illumination (in some cases, in a coordinated manner with other nodes of a lighting network) in an industrial environment is further configured to serve as a node of a wireless process control or industrial network, which may be a mesh and/or time-synchronized wireless network. Upon detecting a loss of mains power and/or other triggering condition, the luminaire node allocates an amount of available battery power to maintain the routing of process control messages, and allocates at least some of a remaining amount of available battery power (if any) for performing lighting activities such as driving illumination and/or lighting-related communications. The allocations for (e.g., the relative priorities of) support for process control and support for lighting activities may be based on an allocation configuration and/or based on instructions received from other components of the process control network and/or the lighting network, which may include user interface devices.

摘要： The present disclosure envisages a housing (1000). The housing (1000) has an operative upper compartment (200) and an operative lower compartment (100). A first lid (110) and a second lid (210) cover the lower and the upper compartments (100, 200) respectively. The lid (210) is openable. A panel (400) is configured to be inserted between the lower compartment (100) and the upper compartment (200) thus forming a partition between the compartments. The housing (1000) of the present disclosure, when utilized for housing data distribution elements and electrical power distribution elements separately in its compartments, provides safe access to the data distribution elements and prevents risk of touching live electrical components.

摘要： An interface circuit that facilitates communicating information between a first system and a second system comprises a first group of ports, a second group of ports, and routing circuitry. The first group of ports is configured to be electrically coupled to the first system. The second group of ports is configured to be electrically coupled to the second system. The routing circuitry is electrically coupled to the first group of ports and the second group of ports. The routing circuitry is configured to facilitate communicating first information applied to a first port of the first group of ports to a pair of ports of the second group of ports. The routing circuitry is further configured to facilitate communicating second information between the pair of ports of the second group of ports and a pair of ports of the first group of ports when a particular signal is applied to a particular port of the second group of ports.

摘要： A luminaire whose primary operation is to provide ambient or focused lighting in a hazardous environment is further configured to communicate, within the hazardous environment, alert and/or detected events or conditions via visual sequences. Different visual sequences uniquely identify respective alerts and/or detected conditions, which may include conditions occurring at the luminaire and/or conditions occurring within the hazardous environment. Different visual sequences are defined by respective blink sequences stored in a blink sequence library at the luminaire. Blink sequences are configurable, are distinguished by different amplitudes, frequencies, duty cycles, and other energization/de-energization waveform characteristics, and are applied to one or more illumination sources of the luminaire to thereby generate corresponding visual sequences in the hazardous environment. Visual sequences generated by hazardous environment luminaires allow personnel within the hazardous environment to be informed or alerted to critical conditions upon their occurrences, even without the use of a portable computing device.

摘要： A smart luminaire system in which a primary luminaire controls and/or communicates with a set of one or more secondary luminaires may be disposed in a hazardous environment, such as an industrial process plant, manufacturing facility, oil refinery, etc. The primary luminaire may send driving commands to the set of secondary luminaires via an analog portion of a hybrid wired communication interface, and the driving commands may cause a driver of a second luminaire to energize on-board illumination source(s) at various intensities. The primary luminaire may send and/or receive administrative messages to/from the secondary luminaires via a digital portion of its hybrid wired communication interface. The smart luminaire system may be a stand-alone system, or may communicate with a controller or back-end system via a wireless communication interface of the primary luminaire, e.g., to receive control instructions and/or to send consolidated administrative messages on behalf of the smart luminaire system.

摘要： The present disclosure relates to the field of luminaire control systems and discloses a system (100) for dynamic switching control of a luminaire (116). The system (100) comprises an ambient light sensor (102), an infrared sensor (104), and a control unit (106). The ambient light sensor (102) senses ambient illumination level and generates a light detection signal representative of the sensed ambient illumination level. The infrared sensor (104) senses infrared radiation of ambient light in the vicinity of the luminaire (116) and generates an infrared radiation detection signal. The control unit (106) cooperates with the ambient light sensor (102) and the infrared sensor (104) to generate a control signal for controlling the operation of the luminaire (116). The control unit (106) also updates the pre-determined turn on and turn off threshold lux values based on level of contamination on the surface of the ambient light sensor (102).
