摘要： A method and apparatus for a tunable optical spectrum analyzer that can measure the optical spectrum of a demultiplexed DWDM signal are presented. The signal level and Optical Signal to Noise Ratio (OSNR) of an individual channel of the DWDM signal can be obtained from the measured optical spectrum. The device employs a rapid tuning and detection technique to obtain the optical spectrum of the incoming signal. In a preferred embodiment the apparatus is fabricated on a single chip resulting in a compact measurement device. Using the device of the preferred embodiment, single channel OSNR can be determined in as small a time interval as approximately 225 microseconds. Using an array of these devices an entire DWDM mixed signal can be monitored as to OP and OSNR in the same time interval.

摘要： A system, method and device for AO2R is presented. The AO2R system presented is redundant, containing multiple pathways for the input and output signals to travel. The system carries out both the regeneration and reshaping functions in the optical domain, and returns a clean output signal at the same bit rate and in the same format as the input signal, on a wavelength of choice. As an all optical device, the apparatus is bit rate and format transparent, and requires no optical-electrical-optical conversion. The system's built in redundancy and symmetry allows less than perfect yields on components to be tolerated, thus increasing the utility of devices manufactured with less than perfect yields. In alternative embodiments the redundancy aspect of the invention can be extended to any optical signal processing device, thus facilitating high availability optical signal processing.

摘要： Systems, methods, devices, and applications for managing a binge eating disorder (BED). A smartphone and server application may be provided for monitoring and treating BED. Ecological Momentary Assessment (EMA) may be used for automated and/or manual acquisition of data related to triggers associated with BED. Risk factors may be captured in real-time to provide data to both patients and clinicians. For manual data acquisition, the user may be prompted to input emotional states, urges to binge, eating behavior, and binge episodes. For automated acquisition, time, place (e.g. via GPS), medicine adherence, and physical activity may be recorded. The user may be provided with alerts and/or interventions when it is determined that they are at risk of binging.
