Abstract: Systems and methods for providing a head-up display using a holographic element formed on a visor of a wearable element (e.g., a helmet) are disclosed. Light projectors along with corresponding optics are positioned on both sides of a user's head within the wearable element. Light from a light projector is directed towards the holographic element to reflect towards the eye on the opposite side of the head from the light projector. With light reflecting from both light projectors, images are perceived by the user is being positioned on a virtual screen where the virtual screen is positioned outside the wearable element. Images on the virtual screen are displayed stereoscopically and with a large field of view for the user.

Abstract: Techniques are disclosed relating to an improved computer vision system for operators of enclosed vehicles. In various embodiments, a computer system receives a first group of video feeds from a first group of one or more cameras located on an exterior of a vehicle. The computer system creates from the first group of video feeds, a combined video feed for a user that depicts a unified view of an external environment of the vehicle from a point of view that is based on position information and orientation information for the user. The computer system further creates a modified video feed by overlaying the combined video feed with non-obscuring reference markers that indicate a position of one or more reference points in the interior portion of the vehicle. The computer system provides the modified video feed to a display device for display in the user's field of vision.

Abstract: A monitoring system for a bioreactor is disclosed. The monitoring system includes a cuvette arranged to receive a fluid from a bioreactor, wherein the fluid includes a portion of a biomass. The system further includes a light source arranged to project light, at wavelengths absorbable by the biomass, into the cuvette. A sensor is arranged to detect portions of the light that are not absorbed by the biomass. The system further includes a controller coupled to receive an indication of an amount of light detected by the sensor. The indication of the amount of detected light is usable to determine an amount of biomass in the cuvette.

Abstract: A photobioreactor apparatus is described. The photobioreactor provides a system for growth of biological organisms such as algae. The photobioreactor system includes a plurality of transparent conduits coupled between two manifolds. Fluid and feedstock are flowed through the conduits and light is provided at a growth wavelength for growth of biological organisms in the conduits. The manifolds may include passages that allow the fluid and feedstock to flow linearly through the conduits (e.g., from one conduit to the next). The linear or series flow of the fluid and feedstock through the plurality of conduits provides an efficient and cost-effective approach for growth of biological organisms.

Abstract: Systems and methods for cleaning a photobioreactor apparatus are described. Cleaning devices are described that include flexible members coupled to a propulsion member. The cleaning devices may be moved through tubes of the photobioreactor apparatus using the propulsion member. As the cleaning devices move, the flexible members may make contact with walls of the tubes, thereby cleaning the walls of the tubes. Cleaning devices are also contemplated that include particles with some rigidity that intermix with the fluid inside the tubes and clean the walls of the tubes as the particles contact the walls.

Abstract: Systems and methods for providing an active display of a user's environment on a wearable element (e.g., a helmet) are disclosed. Displaying an active display may include displaying a head-up-display on a display screen on the wearable element that is positioned to cover the field of view of the user when the user wears the wearable element. The head-up display may include a display generated from images (e.g., video) captured by one or more image capture elements (e.g., cameras) coupled to the wearable element. In certain instances, the head-up-display replaces the field of view of the user while the wearable element is worn by the user. The head-up-display may also display data received from one or more sensors coupled to the wearable element and data received from another data source in wireless communication with the wearable element.

Abstract: Systems and methods for verifying physical measurements taken for bioreactors are disclosed. Physical measurements may be taken using one or more sensors coupled to a bioreactor. The sensors may measure properties of the bioreactor or properties of materials within the bioreactor. Verifying the physical measurements may be implemented to enable proof of physical work being completed by the bioreactor.
