Abstract: A tracking device can use a permanent encryption key pair to encrypt a temporary private key that corresponds to a set of diversified temporary public keys. When a community mobile device subsequently detects the tracking device, the central tracking system provides a diversified temporary public key to the community mobile device. The community mobile device uses the diversified temporary public key to encrypt location data representative of a location of the community mobile device, and provides the encrypted location data to the central tracking system. When a user subsequently requests a location of the tracking device from the central tracking system, the central tracking system provides the encrypted temporary private key and the encrypted location data to a device of the user, and the device can decrypt the encrypted temporary private key using the permanent encryption key pair, and decrypt the encrypted location data using the decrypted temporary private key.

Abstract: Apparatus and processes to grow a biomaterial made of aerial mycelium by sensing and controlling airborne mist concentration, regardless of relative humidity. A growth matrix comprising a growth medium and a fungus, is grown under controlled environmental conditions to produce a mycelium product. To control growth conditions precisely and efficiently, airborne mist is electronically detected using one or more sensors, configured to measure airborne mist concentration visually, optically, chemically, electromagnetically, or by laser, ultrasonically, with radar, or other means. Electronic detection of airborne mist using one or more sensors generates a signal that is transmitted to a processor that can either maintain, increase, or decrease airborne mist concentration in a growth environment. The present invention provides processes of growing mycelium that are repeatable and resource efficient, while providing high quality and quantity mycelium-based products.

Abstract: A tracking device can use a permanent encryption key pair to encrypt one or more temporary encryption key pairs, which can then be provided to a central tracking system. When a community mobile device subsequently detects the tracking device, the central tracking system provides an encrypted temporary encryption key pair to the community mobile device.
