Abstract: Systems and methods to mimic a target food item using artificial intelligence are disclosed. The system can learn from open source and proprietary databases. A prediction model can be trained using features of the source ingredients to match those of the given target food item. A formula comprising a combination of most relevant source ingredients and their proportions can be determined using the trained prediction model. A set of existing recipes can be used as a dataset to train a recurrent neural network (RNN) and/or other suitable models. The RNN can be used to determine a recipe to mimic the target food item. The recipe may comprise a cooking process for the set of ingredients in the formula and can be cooked by a chef. The recipe may be further modified as necessary based on human feedback on sensorial descriptors.

Abstract: Techniques to suggest chemical compounds with a desired flavor profile or that can be used to recreate functional properties of a target chemical compound, using artificial intelligence, are disclosed. An artificial intelligence model is trained on source chemical compounds with known flavors. The artificial intelligence model learns relationships between the source chemical compounds and their known flavors and generates source chemical compound projected embeddings and true flavor projected embeddings. From either the source chemical compound projected embeddings or the true flavor projected embeddings, one or more chemical compounds for the identified target chemical compound or the identified desired flavor profile may be determined based on a similarity search.

Abstract: A gastrointestinal simulator system includes a thermoregulated bath, two glass beakers situated within the thermoregulated water bath, and a pump. The beakers simulate the stomach and intestines and are coupled together using a tube. A sieve, positioned within the “stomach,” has a plurality of 2 mm holes on its surface to mimic in vivo conditions, where only particles smaller than 2 mm in diameter are transferred to the “intestines.” These collected particles move from “stomach” (specifically, from the sieve) to the “intestines” through the tube coupling the beakers. Cameras may be located inside the water bath for monitoring/recording of the digestion. Alerts, such as voice alerts, may be generated to notify users of any important information and instructions. After digestion, reports of the digestion are automatically generated and stored in a data repository. One or more users are notified that the reports are available for access.

Abstract: An edge-emitting semiconductor laser and fabrication method is disclosed that includes a second, passive waveguide and cladding layer disposed above the multi-layer arrangement of a first waveguiding layer and a first cladding layer.

The resulting configuration exhibits an improved coupling efficiency by maintaining the propagating optical mode within the active waveguiding layer and away from the regrowth interface.

Abstract: A raised cosine waveform is used for the drive signal input to an optical device that exhibits a nonlinear time domain response (e.g., tunable optical filter). The raised cosine waveform (either current or voltage) exhibits significantly fewer high frequency components than conventional drive signals and, as a result, reduces the oscillatory movements of the device as it is settling into a target position. In the specific example of a MEMS tilt mirror as used to tune a nonlinear optical filter, the raised cosine drive signal allows for the tilt mirror to quickly settle into a new position and avoid the prolonged oscillatory motion known to limit the responsivity of prior art tunable optical filters.

Abstract: A semiconductor laser is formed to include a current blocking layer that is positioned below the active region of the device and used to minimize current spreading beyond the defined dimensions of an output beam's optical mode. When used in conjunction with other current-confining structures typically disposed above the active region (e.g., ridge waveguide, electrical isolation, oxide aperture), the inclusion of the lower current blocking layer improves the efficiency of the device. The current blocking layer may be used in edge-emitting devices or vertical cavity surface-emitting devices, and also functions to improve mode shaping and reduction of facet deterioration by directing current flow away from the facets.

Abstract: A system for communicating supervisory information between amplifier nodes in an optical communication network utilizes modulation of an included pump source to superimpose the supervisory information on data signals (typically customer data signals) propagating between the amplifier nodes transmitted customer signals. The modulated pump appears as a modulated envelope on the amplified data signal exiting the amplifier node, and may be recovered by suitable demodulation components located at the second node (i.e., the destined receiver of the supervisory information). The supervisory information may include monitoring messages, provisioning data, protocol updates, etc., and is utilized as an input to an included modulator, which then forms a drive signal for the pump controller.
