Abstract: A water filtering system includes providing light deep into a liquid used in applications such as the cultivation of both attached and suspended photosynthetic organisms. The system is configured to inject a stream of bubbles into the liquid and a light source is configured to shines light through the bubbles. The bubbles allow some light to travel deep into the liquid along the length of the bubble stream and scatter/deflect some light out of the bubble stream and into the surrounding liquid including screens for growing algae.

Abstract: A principal application may be executed on a principal computing device. A surrogate application may be executed on a surrogate computing device. The surrogate application running on the surrogate computing device may be a surrogate for the principal application running on the principal computing device. The principal application running on the principal computing device and the surrogate application running on the surrogate computing device may form multiple presences of the principal application on separate computing devices. Information may be relayed between the principal application running on the principal computing device and the surrogate application running on the surrogate computing device.

Abstract: A proxy device may organize a set of local devices as members of a union. The proxy device may create a set of virtual peripheral devices. The set of virtual peripheral devices may represent a set of physical peripheral devices connected to the set of local devices. The proxy device may communicate the set of virtual peripheral devices to a remote device.

Abstract: A proxy device may change compression of data for a set of local devices. The proxy device may receive compressed data from a remote device, generate first transformed data based on reduction of compression of the compressed data, and transmit the first transformed data to one or more local devices. The proxy device may receive data from a local device, generate second transformed data based on increase in compression of the data, and transmit the second transformed data to the remote device.

Abstract: A water filtering system is provided for growing algae that filters the water. The system may include a container having a cylindrical inner surface and an opening at one end of the container. A clear central core including a cavity may be disposed inside the container and a light source may be disposed inside the cavity of the clear central core. A screen mesh may be disposed inside the container such that a surface of the screen mesh is parallel to the cylindrical inner surface of the container. The system may include an inlet configured to route water into the container and an outlet configured to route water from the container. A lid may cover the opening of the container.
