Abstract: A method for creating a cryptographically secured digital asset includes: a. using at least a first activity data sensor to collect data relating to an activity carried out by a user, b. transmitting the data to a processing system, c. using the processing system to generate a digital asset based on the data, and d. cryptographically securing the digital asset. A system for creating a cryptographically secured digital asset includes at least a first activity data sensor configured to collect data relating to an activity carried out by a user, and a processing system configured to receive the data from the first activity data sensor, generate a digital asset based on the data, and cryptographically secure the digital asset.

Abstract: Dual sided coating system and method for coating substrates, such as substrates useful as battery electrodes. In certain embodiments, the system includes an inline calender station positioned between the dryer and the rewind of the substrate; i.e., positioned downstream, in the direction of substrate (or web) travel, of the dryer, and upstream of the rewind. In certain embodiments, the calender operation is positioned immediately downstream of the dryer; no intermediate equipment that processes the substrata, such as a vacuum dryer, is positioned between the dryer and the calender. Advantages of such a system and method include twice the throughput compared to single side coating operations, a smaller equipment footprint compared to tandem coating lines, lower capital cost and operating cost compared to tandem coating lines, and fewer issues with wrinkles in the substrate.
