Abstract: Apparatus, device, and methods for fragmenting high molecular weight molecular ions, such as peptides or proteins, by treating the ions with predetermined wavelengths of light are described. Vacuum ultraviolet radiation as a source of predetermined wavelengths of laser light is described in one embodiment. A device (50) is described having a sample, such as a peptide, protein, protein digest, and the like enters through inlet (55) and is irradiated with a first source of light (60), which illustratively may be a laser light. The first source of laser light is illustratively at a wavelength and energy sufficient to convert molecules in the sample into molecular or precursor ions.

Abstract: A communication signal receiver and associated method are disclosed. A plurality of communication signals are received at an atenna array and time multiplexed into a single multiplexed signal. Each of the communication signals comprises an unknown mixture of a plurality of source signals from a plurality of communication signal sources. A signal separation network is configured to separate the K source signals from the multiplexed signal.

Abstract: A system and method for receiving communication signals is provided. According to the method, a plurality of communication signals is received, each communication signal comprising one or more source signals. The plurality of communication signals are multiplexed into a multiplexed signal, which is then converted into a baseband signal. The baseband signal is sampled to produce a digital multiplexed signal comprising a plurality of samples. The samples are interpolated to generate respective interpolated digital signals, which are then subject to a blind signal separation operation to separate each of the source signals.

Abstract: A circuit and method for generating a delayed event following a trigger pulse occurring at a random time between clock pulses is disclosed. The circuit includes a clock circuit, a voltage converter, an analog-to-digital converter circuit, a memory storage circuit, and a summing circuit. The method includes representing the time between the triggering pulse and a subsequent clock pulse as a voltage, converting the voltage to a stored digital value, and defining a desired delay time by adding a first time determined by counting a predetermined number of clock cycles to a second time determined by converting the stored digital value first to an analog value and then to a time value.

Abstract: A control system (12) for a power supply (14), such as a high voltage power supply, includes a control circuit (16) and a feedback circuit (18, 28, 30). The feedback circuit (18, 28, 30) is configured to produce a feedback signal indicative of the voltage of the power supply output. The control circuit (16) is configured to control the power supply (14) based on the feedback signal and a predetermined voltage value to maintain the output of the power supply (14) at about the predetermined voltage value. A portion of the feedback circuit (18, 28, 30) may be included in an isolation shield (88) to improve the accuracy of the feedback signal.

Abstract: A visually clear and substantially colorless antimicrobial-containing solution comprising at least 20 weight percent of an alkoxylated monoalkanolamide surfactant represented by formula II: wherein: R1 represents a hydrocarbon radical; R2 represents a hydrogen atom, —CH3 or —CH2—H3 radical; and x independently represents at least 1. The antimicrobial-containing solutions are suitable for readily mixing into cosmetics and disinfectant cleaning products.

Abstract: In a method of processing an input signal, the input signal is divided into a plurality of subbands with the aid of bank of complex valued, single-sided subband filters. The single-sided frequency spectra of the resulting subbands make aliasing negligible at near twice the critical downsampling rates.

Abstract: A plug and switch assembly wherein the switch assembly is connected to a cable assembly provides convenient handling of electrical cables to supply electricity, for instance to airplanes on the ground.

Abstract: An electrode has a substrate and a finely divided active material on the substrate. The active material is ANi.sub.x-y-z Co.sub.y Sn.sub.z, wherein A is a mischmetal or La.sub.1-w M.sub.w, M is Ce, Nd, or Zr, w is from about 0.05 to about 1.0, x is from about 4.5 to about 5.5, y is from 0 to about 3.0, and z is from about 0.05 to about 0.5. An electrochemical storage cell utilizes such an electrode as the anode. The storage cell further has a cathode, a separator between the cathode and the anode, and an electrolyte.
