摘要： An uninterrupted power supply (UPS) device with uninterrupted neutral from input to output utilizes the same converter for converting rectified AC power and battery power to positive and negative high voltage (HV) rails. A simple circuit is utilized for connecting the battery to the conversion components of the PFC circuit without adverse affect on the performance of the PFC circuit, and while holding the battery substantially connected to neutral. In a first embodiment, the circuit comprises a simple combination of four diodes and a pair of high pass capacitors arranged so that in both power line and battery supply modes the battery is balanced around neutral. In a second, preferred embodiment, one terminal of the battery is connected directly to neutral.

摘要： A method and apparatus for calculating fast Fourier transforms FFTs. An FFT of a given size is formatted using tensor product principles for implementation in apparatus or by software such that the same reconfigurable hardware or software can calculate FFTs of any dimension for the selected FFT size. The FFT is factored into an input permutation and successive stages for computing tensor products of dimensionless Fourier transforms of a relatively small base size and twiddle factors, with load-stride permutations between computation stages. The basic building blocks of the circuitry can be reconfigurable for maximizing use-flexibility of the hardware or software. Examples of digital circuit apparatus configured to compute dimensionless formatted FFTs are presented.

摘要： There is presented an apparatus and method of locating a reflective anomaly in an optical fiber. An optical generator is positioned at one end of a light path extending to and from a reflective anomaly in an optical fiber, and periodic pulses of light are injected into the fiber. A bend coupler containing directional optical detectors is clamped to the optical fiber in mid-span, between the optical generator and a reflective anomaly, and light energy is tapped. The coupler is capable of detecting and discriminating light travelling in both longitudinal directions. After signal conditioning and digitization, the light pulses are submitted to a logical network to initiate a timer that measures a time interval between the event of an interrogating light pulse, and its reflection, the result being memorized in a buffer. A microprocessor controls the system, and computes distance between the attached bend coupler and the reflective anomaly as a function of the memorized time interval. The result is then displayed for the user. The system enables a fault to be rapidly and accurately located in a multidrop installation without violating intermediate fibers.

摘要： A UPS device adapted for parallel connection to a load along with one or more other UPS devices, having circuitry for sharing of the load, including load harmonics. A feedback network has an error signal circuit which generates an error signal representative of the difference between the actual current provided by the device and the designated share of current it should provide. The error signal is transformed by a value representative of the effective output impedance of the UPS inverter, whereby the inverter is controlled to share the fundamental of the load current as well as the harmonics.
