摘要： An electronic ballast has control circuitry to operate a gas discharge lamp in both full and dimmed illumination modes. A dimming controller serves as the mechanism to permit a selection between full and dimmed illumination modes. The dimming controller signal has a dimming request range which describes the range of dimming controller signal magnitudes. The electronic ballast also includes a full power circuit having a power control coupled to the dimming controller output to receive the dimming controller signal. The full power circuit also has a full power output that can couple to the lamp. When the full power circuit receives the dimming controller signal, via the power control, and the dimming controller signal is not in the dimming request range (i.e. the full illumination mode has been selected), the full power circuit generates a full power signal capable of driving/operating the lamp(s) in the full illumination mode. A filament heating circuit has a heating input coupled to the reduced power circuit, to receive the reduced power signal, and a heating output that can couple to the filaments of one or more lamps. When the reduced power signal is present, the filament heating circuit generates and provides a filament heating signal to the filaments, via the heating output. The filament heating signal maintains the temperature of the filaments when the lamp(s) are operated in the dimmed illumination mode. Further, the filament heating signal is responsive to the reduced power signal.

摘要： A chainsaw tensioner that includes set of bevel gears. The input gear is connected to a knob to be operated to the user. Torque from the input knob is transferred to an output bevel gear that is connected to a threaded rod. A plate travels about the threaded rod and is mated with the chain guide bar. When the rod is rotated, the plate and the chain guide bar translate linearly to either tighten or loosen the chain around the periphery of the chain guide bar depending on the direction of rotation of the knob.

摘要： A receiver in an OFDM communication system includes a power detector and a gain controller. The power detector detects for total received power of a received OFDM signal, e.g., by computing the power of the data samples from an ADC and averaging the power. The gain controller adjusts the gain of the receiver in discrete gain steps and in one direction, e.g., from the lowest gain state to the highest gain state, based on the detected total received power. The gain controller initializes the receiver to the lowest gain state. Thereafter, the gain controller detects for low total received power, e.g., by comparing the detected total received power against a predetermined threshold. The gain controller transitions to a higher gain state if low total received power is detected and maintains the current gain state otherwise.
