Abstract: Methods and systems for connecting short term rental with distributed infrastructure are provided. According to one example, a server maintains access to a plurality of property data contracts on a decentralized blockchain ledger, each property data contract associated with a real property in a locale and a cancellation policy data contract. The server receives a booking data operation including a cryptocurrency transaction and a cryptocurrency address and verifies the booking data operation relative to the cancellation policy contract. Responsive to the verifying, the server approves the booking data operation, processes the cryptocurrency transaction, and updates the decentralized blockchain ledger. After the booking data operation has been approved, the server runs a token data operation to provide a token to the cryptocurrency address associated with the user electronic device.

Abstract: A pressure detector is installed in close proximity to the nozzle of a 3D printer and detects a plugged nozzle by the sudden increase in the pressure of the extruded material. The printing process is paused until the nozzle is cleared manually or automatically. For manual cleaning a notification can be automatically sent to the user of the printer. The pressure sensor can be part of the nozzle housing and be designed to detect external forces as well, in order to serve as a bed levelling sensor.
