Systems, methods, and computer readable media to register images in real-time and that are capable of producing reliable registrations even when the number of high frequency image features is small. The antenna has an effective area greater than its physical area. The shaft portion is formed of a pipe having oil discharge holes formed thereon at predetermined intervals. When the insulating sheet is uncured, the insulating sheet has a glass transition temperature Tg of 25\xb0 C. The systems and methods allow real time communications between the database and the access devices utilizing existing communications WI-FI infrastructure in the facility while minimizing loss of battery life of the access devices by employing the radio network to target all or a portion of the access devices for communications when needed. The ceramic plates are disposed vertically in the housing in a parallel manner and the outlet hole is disposed in an upper portion of the housing, such that when a fluid flows through a flow path formed along the ceramic plates, bubbles, generated by the fluid heated by the ceramic plates, ascend toward edges of the ceramic plates.
