Abstract: A multiple optical frequency monitoring assembly includes a first light source configured to generate a first light beam; a second light source configured to generate a second light beam; combiner optics configured to combine the first light beam and the second light beam into a combined light beam; a beam splitter configured to split the combined light beam into a monitored light beam and a reference light beam; an interferometer configured to receive the monitored light beam and output the monitored light beam as a monitored output light beam according to a resonant frequency response; filter optics configured to separate the monitored output light beam into two output beams; a detector configured to measure the two output beams; and a controller configured to tune the first light source and the second light source based on the two measured output beams and the reference light beam.

Abstract: An optical receiver includes an integrated receiver chip includes a data port configured to receive an optical data signal derived from a receive optical signal, a first waveguide coupled to the data port and configured to transmit the optical data signal from the data port to an optical waveguide circuit of the integrated receiver chip, a power monitoring port configured to receive an optical monitoring signal derived from the receive optical signal, and a second waveguide coupled to the power monitoring port and configured to transmit the optical monitoring signal to a monitor photodiode that is monolithically integrated in the integrated receiver chip. The monitor photodiode is configured to convert the optical monitoring signal into an electrical signal representative of an optical input power of the receive optical signal.

Abstract: A press for shaping an absorbent tampon blank into a shaped tampon pledget includes a central cavity arranged and configured to accommodate an absorbent tampon blank having a front portion and a back portion. The main longitudinal axis of the press passes in the middle of the central cavity and a plurality of penetrating dies are arranged radially around the said main longitudinal axis. Each penetrating die has a pressing face on at least a fragment of its side facing the central cavity. The said press comprises at least one cam to actuate the plurality of penetrating dies. Furthermore, the plurality of penetrating dies comprises at least one penetrating die having a pressing face with a first shaped longitudinal profile, and least one penetrating die having a pressing face with a second shaped longitudinal profile.

Abstract: A doming tool for manufacturing absorbent tampon includes a plurality of stations made of devices for shaping a tampon pledget tip, and a hollow mandrel engaging with the stations. The stations are supported by at least one mounting plate.
