Abstract: A mycelium growth bed for growing a solid substrate-bound mycelium through which the mycelium composite is easily and readily removed. This is achieved through the use of a perforation layer embedded between the mycelium substrate and the mycelium composite so as to create a uniform structural weakness and thereby enhancing harvesting abilities of the ex-substrate mycelium via a greatly reduced and uniform tear strength. The perforation layer, through which the mycelium grows, allows for the gated and controlled extrusion of a matrix of colonial cells that may be easily and uniformly delaminated from the underlying mycelium substrate.

Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment may vary for different users and may change over time (e.g., as a user moves around and/or the HMD slips or is otherwise displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

Abstract: An electronic device for measuring parameters related to activities of a user and determining stamina of the user are disclosed herein. A stamina potential metric may be determined from long-term activities that reduce and rebuild stamina potential. A stamina left metric may be determined. The stamina left metric is indicative of short-term work that the user can perform during a workout. The electronic device may track the stamina potential and the stamina left of the user as well as the various parameters associated with the activities performed by the user and track and update the user’s performance metrics. Furthermore, the device may compare a determined amount of stamina required to perform activities with the stamina potential of the user and recommend activities.
