摘要： The present disclosure provides high-degree reconfigurable optical add-drop multiplexing (ROADM) systems using bi-directional wavelength selective switches (WSSs) and optical circulators. A single WSS is utilized on each degree of a node in a bi-directional manner, i.e. both ingress and egress share the same WSS. Advantageously, the present invention eliminates conventional splitters/combiners thereby capping intra-node insertion loss to a certain value regardless of the number of degrees. More importantly, the present invention reduces noise penalty associated with high-degree nodes while minimizing cost.

摘要： The present invention provides systems and methods to adaptively control amplifier target power to maintain signal launching power as per design in networks with wavelength selective switch (WSS)-based reconfigurable optical add-drop multiplexers (ROADMs) using micro-electromechanical system (MEMS). Accordingly, signal OSNR does not collapse faster for WSS-based ROADMs than other similar configured system without WSS-based ROADM. In order to correct amplifier target power, the present invention utilizes system information about side-lobe size and OSNR at each amplifier. Related information, such as ASE level and size of side-lobes at each channel from upstream amplifiers, is passed to the network controller at each amplifier. Meanwhile, with target signal level and local WSS attenuation setting (given side-lobe size vs. WSS attenuation known) of each channel, the amplifier calculates what is total output power should be and adaptively maintains that power.

摘要： The current invention involves a desorption corona beam ionization source/device for analyzing samples under atmospheric pressure without sample pretreatment. It includes a gas source, a gas flow tube, a gas flow heater, a metal tube, a DC power supply and a sample support/holder for placing the samples. A visible corona beam is formed at a sharply pointed tip at the exit of the metal tube when a stream of inert gas flows through the metal tube that is applied with a high DC voltage. The gas is heated for desorbing the analyte from solid samples and the desorbed species are ionized by the energized particles embedded in the corona beam. The ions formed are then transferred through an adjacent inlet into a mass spectrometer or other devices capable of analyzing ions. Visibility of the corona beam in the current invention greatly facilitates pinpointing a sampling area on the analyte and also makes profiling of sample surfaces possible.

摘要： According to the invention, a system and method of reducing noise interference in a way that employs pseudorandom coding. A transmitter and receiver are provided to send and receive a string of non-periodic pulses. The string of non-periodic pulses can be a sequence of pseudorandom codes. The random transmission of pulses in a non-periodic manner promotes a significant immunity to periodic interferences of constant noise operating in a surveillance area. The string of non-periodic pulses can be mutually spaced and binary, in the form of 0 or 1, and can include several bits per cycle to measure the mean and standard deviation of the string of non-periodic pulses received. A circuit is coupled to the transmitter and receiver for comparing the portion of the string of non-periodic pulses received with the string of non-periodic pulses transmitted; and whereby an alarm in triggered if the portion of the string of non-periodic pulses is above a threshold value.
