Abstract: A support ring is for mounting of a soft box on a light source. The support ring includes a connector for attachment of the support ring to the light source, and at least one cavity configured to receive support pins of the soft box. The cavity further includes a first and a second support element arranged to counteract a torque from the support pins, when the support pins are in an inserted position in the cavity. At least one entry element on a radial outside of the cavity is arranged to counteract a force required to bend the support pin to an angle where the support pin can be inserted into the cavity.

Abstract: A system for power supply synchronization in an Radio Frequency Identification (RFID) reader is shown and described. In one embodiment, the system includes one or more switched mode power supply devices and a signal generator. Each of the switched mode power supply devices provides power to at least one component of the RFID reader. The signal generator transmits a synchronization signal of a controlling frequency to each of the one or more power supply devices. In one embodiment, the system includes a signal processing unit that is configured to reject one or more spectral components from the output of the RFID reader.

Abstract: Methods and apparatus for managing an optical network using pilot tones are provided. One method includes selecting an optical path having a plurality of nodes from a database defining an expected optical network. A detected list of pilot tones associated with each node of the selected optical path is generated. An expected list of pilot tones associated with each node of the selected optical path is generated. The detected and expected lists are compared to identify any mismatched nodes.

Abstract: A pilot tone generator receives optical energy from an optical communication medium carrying a plurality of optical signals. Each optical signal carries data modulated at a unique wavelength and further modulated with a unique identification signal. The identification signal has an amplitude corresponding to an optical power of the associated optical signal. The pilot tone receiver detects each identification signal from the optical energy received and determines its corresponding amplitude. The pilot tone receiver calculates the optical power of each optical signal in the optical energy in response to the amplitude of the associated identification signal.

Abstract: A method and system provide for sensing multiple wavelengths simultaneously in a single wavelength sensing device. The system may have a plurality of laser signals and a plurality of identifiable modulation signals. A respective laser signal of the plurality of laser signals is combined with a respective identifiable modulation signal of the plurality of identifiable modulation signals so that each of the laser signals is identifiable. A combined optical signal is then formed from the modulated laser signals. A sensor has an input port that receives the combined optical signal. The sensor identifies, for each of the modulated laser signals, a respective laser signal via the identifiable modulation of the respective modulated laser signal.

Abstract: Methods and apparatus for managing an optical network using pilot tones are provided. One method includes generating a list of pilot tones contributed by a selected node to each of its target nodes. Network pilot tone sources are re-configured so that a pilot tone source of any optical path incorporating one of the target nodes has a value distinct from the listed pilot tones. The selected node can then be added to the network. Another method includes generating a list including all selected network nodes to be incorporated into a new optical path and nodes adjacent to the selected network nodes. Network pilot tone sources are re-configured until a pilot tone source associated with the new optical path has a pilot tone distinct from that of any listed node. The new optical path can then be added to the network.

Abstract: A machine for dispensing coinage change including a conveyor in the form of a belt or plate and including rows of coin receiving apertures or recesses with a mechanism to advance the conveyor means forward in response to a manually operated coin actuated drive mechanism, with the conveyor being advanced beneath a plurality of supply tubes adapted for alignment with corresponding rows of apertures or recesses in the conveyor and extending in the direction of motion of the conveyor. Coinage change is collected from an advanced supply tube only after a supply tube trailing the advanced tube in a particular row of tubes fails to deliver a coin. The conveyor feeding a transfer chute through which coinage change collected by the conveyor gravitates for collection by the operator of the machine.
