Abstract: Static neutralization of a charged object is provided by applying an alternating voltage having a complex waveform, hereinafter referred to as a “multi-frequency voltage”, to an ionizing electrode in an ionizing cell. When the multi-frequency voltage, measured between the ionizing electrode and a reference electrode available from the ionizing cell, equals or exceeds the corona onset voltage threshold of the ionizing cell, the multi-frequency voltage generates a mix of positively and negatively charged ions, sometimes collectively referred to as a “bipolar ion cloud”. The bipolar ion cloud oscillates between the ionizing electrode and the reference electrode. The multi-frequency voltage also redistributes these ions into separate regions according to their negative or positive ion potential when the multi-frequency voltage creates a polarizing electrical field of sufficient strength.

Abstract: A low maintenance AC gas-flow driven static neutralizer, comprising at least one emitter and at least one reference electrode; a power supply having an output electrically coupled to the emitter(s) and a reference terminal electrically coupled to the reference electrode(s) with the power supply disposed to produce an output waveform that creates ions by corona discharge and to produce an electrical field when this output waveform is applied to the emitter(s); a gas flow source disposed to produce a gas flow across a first region that includes these generated ions and the emitter(s), the gas flow including a flow velocity; and wherein, during a first time duration, the output waveform decreases an electrical force created by the electrical field, enabling the gas flow to carry away from the emitter(s) a contamination particle that may be located within a second region surrounding the emitter(s), and to minimize a likelihood of the contamination particle from accumulating on the emitter(s).

Abstract: To optimize memory operations, a mapping table may be used that includes: logical fields representing a plurality of LBA sets, including first and second logical fields for representing respectively first and second LBA sets, the first and second LBA sets each representing a consecutive LBA set; PBA fields representing PBAs, including a first PBA disposed for representing a first access parameter set and a second PBA disposed for representing a second access parameter set, each PBA associated with a physical memory location in a memory store, and these logical fields and PBA fields disposed to associate the first and second LBA sets with the first and second PBAs; and, upon receiving an I/O transaction request associated with the first and second LBA sets, the mapping table causes optimized memory operations to be performed on memory locations respectively associated with the first and second PBAs.

Abstract: A high voltage power supply for a static neutralizer is disclosed. The high voltage power supply includes a resonant converter and a load with an emitter module having an emitter, reference electrode, and a capacitance value. The resonant converter is disposed to have a resonant frequency and an output coupled to the load. The resonant converter generates an output waveform with an amplitude sufficient for generating to ions by corona discharge when the load receives the output waveform. The load is predominantly capacitive when the resonant converter is operating at the resonant frequency.

Abstract: This invention relates to data networks, and more particularly, to platforms, modules and systems for networking at least one device having Fibre Channel node functionality with another device. Networking of Fibre Channel-enabled devices is provided by an apparatus that includes a circuit board having a first set of signal paths; a first transceiver having a first optical I/O port, a first transceiver output and a first transceiver input; a first I/O connection for coupling to a first Fibre Channel port and for receiving signals transmitted by the first transceiver output via a subset of the first set of signal paths; and a second I/O connection for coupling to a second Fibre Channel port and for receiving signals from the first Fibre Channel Port.

Abstract: At least one orifice is added to an AC ionizer with nozzles and ionizing electrodes that are used to remove static charge. The orifice is placed in a location where electrostatic forces are weak and where gas ions can be easily extracted from the ionizer. Ionizer effectiveness is enhanced by recovering gas ions that are normally trapped between the nozzles and under a portion of the ionizer from which the nozzles project. Without the orifice properly positioned, the trapped gas ions are lost by recombination or grounding. With the orifice positioned in an area of weak electrostatic forces, more gas ions are available for discharging the charged object. The combined air consumption of nozzles plus at least one orifice is the same or less than nozzles alone would consume for a given discharge time.

Abstract: Efficient static neutralization of an electrostatically charged object that has a varying distance from an ion generating source, a varying velocity, a large dimension or any these is achieved by using an ionizing cell or bar having a first electrode and a second electrode. The first electrode for receiving a multi-frequency voltage that has a waveform, and the second electrode separated from the first electrode by a first distance and for use as a reference electrode. The waveform is adjusted during neutralization of a moving object based on at least one attribute of the object.

Abstract: A distributed cache module that allows for a distributed cache between multiple servers of a network without using a central cache manager. The distributed cache module transmits each message with a logical timestamp. The distributed cache module of a server that receives the message will delay forwarding of the message to, for example, a client computer, if preceding timestamps are not received. This insures a correct order of timestamped messages without requiring a central manager to allocate and control the transmission of the messages within the network. Each distributed cache module will request and possibly retrieve data from the cache of another server in response to a file request for the data. The data of a file may be accessed by a plurality of servers joined in a file context.
