    摘要: A forced-air electric generator apparatus includes a housing positioned to receive forced-air flow from a forced-air device. A bladed rotor carried by the housing is in fluid communication with the forced air flow. A clutch engages the bladed rotor to drive a generator to produce a generated voltage when the bladed rotor is rotating above a threshold rotational velocity.

    摘要: A method of optical communication includes generating an amplified optical signal from at least a portion of a first optical signal having a first carrier wavelength, λ1. The amplified optical signal is applied to Brillouin media to stimulate generation of a Brillouin effect signal at a wavelength λ2. The Brillouin effect signal is modulated to produce a second optical signal having a second carrier wavelength, λ2. In one embodiment, the first optical signal is a downstream optical signal and the second optical signal is an upstream optical signal of a passive optical network.

    摘要: Methods and apparatus associated with a plurality of serial devices designed to communicate with a bus master in either a daisy chain or a normal configuration are provided. One method includes the step of serially providing a command sequence having a channel identifier to a given device of a plurality of daisy chained devices. The channel identifier is modified as it passes thru each daisy chained device. A specific device is identified or enabled when the channel identifier it receives matches a pre-determined value.

    摘要: An analog front end for communicating discrete multitone modulated signals on a subscriber line includes a transmit block, a receive block, and a hybrid packaged within a same integrated circuit. Upstream data to be transmitted to the subscriber line is pre-processed to eliminate even images. A power spectral density shaping filter subsequently substantially eliminates undesired energy in the upstream data signal. A high pass filter further rejects upstream data from the downstream data signal. The power spectral density filter and the high pass filter enable the use of a first order hybrid network for extracting the downstream data. The analog front end may include an additional analog channel to enable voiceband (e.g., v.90) communication concurrent with non-voiceband (e.g., xDSL) operation. Sample rate conversion is utilized to avoid the use of multiple independent clocks for otherwise incompatible clocking requirements.

    摘要: A subscriber line interface circuit apparatus includes tip/ring sense circuitry generating a tip sense signal and a ring sense signal from three sensed currents, wherein the tip sense signal and the ring sense signal correspond to subscriber loop tip and ring currents, respectively. In one embodiment, the tip/ring sense circuitry includes a current mirror generating first and second mirrored sense currents from a first sense current proportional to a battery feed node voltage of a subscriber loop. Current differencing circuitry provides the tip sense signal from a difference between the first mirrored sense current and a second sense current associated with a tip line of the subscriber loop. The current differencing circuitry provides the ring sense signal from a difference between the second mirrored sense current and a third sense current associated with a ring line of the subscriber loop.

    摘要: A method of optical communication includes providing a plurality of optical signals each associated with a distinct channel of a composite optical signal. A unique pilot tone signature is superimposed on each channel. The spectral composition of each signature includes a plurality of frequencies. In one embodiment, binary frequency shift keying at a frequency fm is used to shift between instantaneous frequencies f1 and f2 wherein f2+Δf=f1−Δf=fc. Choosing Δ ⁢ ⁢ f f m ≈ 1.1602 produces a spectrum having a plurality of dominant components at least some of which have substantially the same amplitude. A method of detecting the presence of a selected pilot tone signature having a plurality n of dominant spectral components F1 . . . Fn includes generating a power spectrum P0(f). Sk(f) is calculated as a product of a plurality of frequency shifted versions of P0(f), where k∈{1 . . . n}. The existence of a dominant spectral component at Fk indicates the presence of the selected pilot tone signature.
