In one embodiment, an electronic cymbal system includes a first pickup configured to generate an electrical signal representative of vibrations in a first cymbal, and a controller configured to receive the first electrical signal and to process the first electrical signal to generate an output. The controller includes a digital signal processor (DSP) configured to subject a version of the first electrical signal to a digital signal processing technique. The digital signal processing technique includes one or more of dynamic range compression, expansion, frequency equalization, harmonic excitation, comb filtering, and pitch shifting. The cymbals may be any of variety of known cymbals, such as hi-hat, crash and ride cymbals, and may be of the perforated type configured to reduce noise for indoor use. Lighting control may be provided to illuminate the cymbal for functional or aesthetic purposes.

The invention relates to a system and method of dispersion measurement in an optical fibre network. The invention provides means for transmitting from a transmitting node, using a single tunable laser transmitter, two consecutive bursts of data at different wavelengths λ1 and λ2 to a receiver node, wherein each burst of data comprises a unique sequence of amplitude modulated data, and wherein the two sequences are injected with a fixed known delay. The delay between the two consecutive bursts of data is maintained by selective switching of the tunable laser, such that clock recovery circuitry at the receiver node remains locked during the delay between the two bursts. The dispersion measurements method of the present invention is based on walk off and bit position detection between two wavelengths suitable for fast optical burst switching network is described. This method does not require an operator, extra equipment, or traffic interruption on the network.

The invention provides an optical burst switch in an Optical Burst Switched (OBS) communication network, said optical burst switch comprising means for monitoring and maintaining mesh of virtual optical paths from a communication node to a plurality of other communication nodes, arranged in a ring network, enabling traffic data to be transmitted and/or received between nodes via a physical optical path. The switch also provides means for sending a data packet probe on a virtual path from a node to each other node in the OBS communication network, wherein data packet probe information received at said switch provides information of availability of the physical optical path for sending traffic data between nodes. The switch can be configured such that the rate at which this path monitoring is scheduled guaranteeing less than 50ms protection switch in the event of monitoring a failed or degraded path.

When dross (20) is removed from a molten-solder reservoir (12), a substantial amount of molten solder is often removed with the dross. This molten solder can be separated from the dross and returned to reservoir via a conduit for reuse. Additionally, a skimmer (77, 168) for removing the dross from the reservoir includes a skimming plate pivotally attached to a displaceable structure; a stop is provided to restrict the degree to which the skimming plate can pivot so that the skimming plate will not pivot more than 90° from vertical to enable the skimming plate to dig into the dross and collect dross when the displaceable structure is displaced toward on outlet of the reservoir. Further still, the displaceable structure (164) of the skimmer (168) can be controlled via acomputer control system storing software code instructions for a motor to extend and retract the displaceable structure such that the skimming plate extends to a position further from the outlet port of the reservoir with each displacement cycle.
