    Abstract: In a coarse wavelength division multiplexing (CWDM) optical transmission system, a distributed feedback (DFB) laser is tuned so that the peak reflection of the grating overlaps with the gain range of the DFB laser. The diffraction grating is tuned so that the peak is positioned on the long wavelength end of the gain spectrum at a selected temperature. The optical transmission system operates in an environment having a wide temperature range (i.e., about −40° C. to about 85° C.). Heat is applied to the laser and as the laser temperature increases, the gain range overtakes the grating peak. When the gain range and the grating peak overlap at increased laser temperature, laser output is improved.

    Abstract: A method and apparatus is presented for providing improved responsiveness of a receiver device. One embodiment includes a receiver device including an avalanche photodiode (APD), a transimpedance amplifier (TIA), and an automatic gain control (AGC) device configured to adjust the reverse bias voltage applied to the APD according to an approximate DC average of the incoming optical signal. A switch in the AGC device may be used to increase or decrease the time constant of an RC combination determining the DC averaging time period, thereby tailoring the response of the AGC device to characteristics of the incoming data pattern. The resulting receiver exhibits improved responsiveness and sensitivity by adapting to varying data patterns including those with data bursts interspersed with gaps.

    Abstract: An apparatus for performing volume measurement of a person, animal or object, and methods of making and using the same are described. The apparatus includes first and second chambers in gaseous communication, first and second pressure sensors that measure the air pressure inside the first and second chambers, a pump configured to move air from or to the first and/or second chambers, and a control system connected to the first and second pressure sensors and the pump. The first and second chambers have a volume that is substantially constant when the internal pressure changes. The control system stores values from the first and second pressure sensors, controls air movement to and/or from the first and second chambers, blocks air transfer between the first and second chambers, and determines the volume of the person, animal or object from pressure measurements before and after an air transfer between the first and second chambers.
