Abstract: Systems and methods for communicating via a network may employ communication devices capable of functioning in a server mode and a client mode. Communication may begin by activating a server mode for a first communication device. The first communication device in the server mode may receive a message from a second communication device, the message comprising an identity associated with the second communication device. The first communication device may retrieve a key associated with the second communication device and verify the identity associated with the second communication device by comparing data in the message from the second communication device with data in the key. A client mode may be activated for the first communication device. The first communication device in client mode may send a message to an address associated with the second communication device, the message comprising an identity associated with the first communication device.

Abstract: An endoscope including an elongated endoscope body sized and adapted for insertion into a passage, such as a passage of the body of a patient. Optical components are carried by the endoscope body to enable viewing of the passage distally of the distal end of the endoscope body within a field of view of the endoscope. An elongated, resilient member is mounted on and carried by the endoscope body such that the endoscope body and the resilient member are a unitary assembly which can be inserted as a unit into the passage. The resilient member extends beyond the distal end of the endoscope body and is capable of contacting material within or forming the passage and relatively displacing the distal end of the endoscope body and such material within the field of view of the endoscope to enhance viewing of the passage with the endoscope.
