    Abstract: A programmable, ultrafast optical delay line based on reversible frequency conversion uses a time-prism pair and no moving parts. A first electro-optic phase modulator acting as a first time-prism shifts the frequency of an incoming pulse train. The pulse train passes through a dispersion element, such as a dispersive fiber, which delays the pulse train by an amount that is directly proportional to the magnitude of the frequency shift, which in turn is proportional to the magnitude of the phase modulator drive voltage. A second electro-optic phase modulator is driven π out of phase to the first modulator and restores the frequency of the delayed pulse train to the original frequency of the incoming pulse train. To reduce pulse broadening effects and enhance performance further, soliton propagation inducing elements can be employed between the time-prisms.

    Abstract: The hand-operated air pump is a mechanical device. The hand-operated air pump compresses atmospheric gas for use in an inflatable structure. The hand-operated air pump comprises a housing and a pump structure. The housing contains the pump structure. The housing transfers externally provisioned motive forces that are required to operate the pump structure. The pump structure compresses the atmospheric gas used in the inflatable structure. The pump structure transports the compressed atmospheric gas to the inflatable structure. The pump structure measures the pressure of atmospheric gas contained in the inflatable structure.
