Abstract: Methods and systems for providing two-way initiated, bi-directional communication with wireless devices using connection-based or connection-less protocols, such as, for example, TCP/IP and UDP/IP, are provided. Example embodiments provide an Address Management Proxy System (“AMPS”), which enables devices and systems connected to a public internet, such as the Internet, to initiate communication with and to send data to wireless devices connected to a private wireless network, without exposing the non-routable private addresses of these wireless devices. The AMPS allocates a public (routable) network address for temporarily use by a requesting device on a public network to communicate with a wireless device on a wireless network. In one embodiment, a pool of public addresses, for example, public IP addresses, is maintained by the AMPS and allocated dynamically to wireless network devices as required.

Abstract: A medical image recording apparatus according to the present invention in which the optical path length of the optical system is extremely short and the number of mechanical operating mechanisms is reduced electronically scans an LED array assembly (14) having a plurality of one-dimensionally arranged LED's with an LED array controller (28) and feeds a photosensitive recording medium (15) in a direction perpendicular to the direction of arrangement of the LED's by means of a motor (17) controlled by a film feed controller (29). The LED array controller and the film feed controller are operated on the basis of commands given from a scanning controller (27) which is controlled by a CPU.
