Abstract: The present application relates to the production of cannabis products, particularly on a large scale, such as at an industrial level. Cannabis is typically a controlled and regulated substance, and so inventory control, security, and traceability of the cannabis may need to be provided. A human-based manual and/or labour-intensive implementation is not scalable, and is therefore infeasible at an industrial level. Disclosed herein are computer systems for inventory control, security systems, and computer methods for facilitating traceability from a cannabis product back to a batch of cannabis plants.

Abstract: A dosage device that includes a cannabinoid-containing substance enables controlled addition of the cannabinoid-containing substance to a liquid to produce a cannabinoid-containing liquid for ingestion. In an embodiment, such a dosage device is provided with a container that has a container body holding a liquid and a cover to seal the container body. A dosage device may also or instead be provided with a cover that includes a coupling structure to releasably couple the cover to a liquid container and a seal to seal the container. Other embodiments, including methods of use of a container, methods that involve providing a cannabinoid-containing substance and adding the cannabinoid-containing substance to a cover, and product packages that include multiple covers, are also disclosed.

Abstract: In one embodiment, an optical directional coupler includes an input terminal configured to receive an input optical signal and a first coupler optically coupled to the input terminal, where the first coupler has a first coupling length, and where the first coupler is configured to couple a first portion of the input optical signal to a first optical leg and a second optical portion of the input optical signal to a second optical leg. The optical directional coupler also includes the first optical leg, where the first optical leg is configured to phase shift the first portion of the optical signal to produce a first phase shift signal and the second optical leg, where the second optical leg is configured to phase shift the second portion of the optical signal to produce a second phase shift signal, and where the first phase shift signal has a phase difference relative to the second phase shift signal.

Abstract: In one embodiment, an optical phase shifter includes a first waveguide phase shifter and a second waveguide phase shifter. The optical phase shifter also includes a first polarization rotator optically coupled between the first waveguide phase shifter and the second waveguide phase shifter, where the first waveguide phase shifter, second waveguide phase shifter, and first polarization rotator are integrated on a single substrate.

Abstract: In one embodiment, an optical phase shifter includes a first phase-shifter configured to phase shift a transverse electric (TE) component of an optical signal by a first phase-shift to produce a TE component of a first signal, and a transverse magnetic (TM) component of the optical signal by a second phase-shift to produce a TM component of the first signal. The optical phase-shifter includes a polarization-rotator configured to rotate the TE component of the first signal to produce a TM component of a rotated signal, and the TM component of the first signal to produce a TE component of the rotated signal. The optical phase-shifter includes a second phase-shifter configured to phase-shift a TE component of the rotated signal by a third phase-shift, and the TM component of the rotated signal by a fourth phase-shift, where the first phase-shifter, the polarization-rotator, and the second phase-shifter are integrated on a substrate.
