    摘要: A battery system for efficiently operating a battery under various circumstances, such as relating to extreme temperature ranges and varying load (i.e. current) ranges. The battery system generally includes at least one first cell having a first chemistry, at least one second cell having a second chemistry and a controller in communication with the first cell and the second cell. The controller is adapted to employ a chemical reaction of the first chemistry in the first cell or the second chemistry in the second cell. The first chemistry is different than the second chemistry, wherein the first chemistry and the second chemistry may be adapted to provide current over varying temperature ranges or to provide current for varying current loads.

    摘要: The invention relates to a phase-locked loop delivering a recovered clock signal from a reference clock signal F.sub.ref in which some transitions are missing. The loop includes a first divide-by-M frequency divider receiving the clock F.sub.ref and delivering a signal of frequency F.sub.ref /M; a phase comparator providing a phase error signal from the signal of frequency F.sub.ref /M, and the output signal from a second divide-by-M frequency divider; a divide-by-K frequency divider providing a signal of frequency F.sub.k from a local oscillator signal of frequency F.sub.oL receiving the phase error signal as a control signal; an adder-counter of the division ratio p/q receiving the local oscillator signal of frequency F.sub.oL and delivering a signal of frequency F.sub.o equal to F.sub.oL *p/q; a mixer delivering a signal of frequency F.sub.n equal to F.sub.o -F.sub.k on the basis of signal of frequency F.sub.k and the signal of frequency F.sub.o ; and a divide-by-N frequency divider synchronized by F.sub.oL, receiving the signal of frequency F.sub.n, and delivering a recovered clock to the second divide-by-M frequency divider.
