Abstract: An optical coherence tomography scanning system traverses its respective scan pattern quickly, typically completing an entire two-dimensional frame faster than a conventional raster scanner completes one raster line segment. To traverse the scan pattern quickly, the system takes fewer A-scans per length of scan pattern than a conventional OCT scanner. To compensate for the sparsity of the sample points along the respective scan line segments, and for gaps between respective line segments of the trajectory, the system acquires and combines several partially overlapping frames for each study.

Abstract: In part, aspects of the invention relate to methods, apparatus, and systems for intensity and/or pattern line noise reduction in a data collection system such as an optical coherence tomography system that uses an electromagnetic radiation source and interferometric principles. In one embodiment, the noise is intensity noise or line pattern noise and the source is a laser such as a swept laser. One or more attenuators responsive to one or more control signals can be used in conjunction with an analog or digital feedback network in one embodiment.

Abstract: A method, system, and computer program product for providing call loop detection and prevention for VoIP SIP based wholesale traffic termination when multiple carriers are involved in handling the same phone call is provided. A method of detecting a call loop includes receiving an originated call, determining whether an origination number of the originated call is a valid phone number, when the origination phone number is invalid, determining a number of calls in a Provisional State with an invalid origination number and the same destination number that were started during a time interval, when the origination phone number is valid, determining a number of calls with the same origination number and the same destination number that were started, but not answered, during the time interval, and when the number of calls per time interval exceeds a threshold for the number of calls, determining that a call loop has been detected.

Abstract: A method, system, and computer program product for detecting the type of NAT firewall using messages provides the capability to determine the type of NAT in use without requiring special purpose hardware or software. A method for determining a type of a NAT firewall may comprise receiving a message from a device inside the NAT firewall, the message addressed to a first IP address and port of a device outside the NAT firewall, transmitting a plurality of messages to the device inside the NAT firewall, at least one of the plurality of messages addressed from the first IP address and port and at least one of the messages addressed from a second IP address and port, receiving responses to at least some of the plurality of messages transmitted to the device inside the NAT firewall and determining the type of the NAT firewall based on the received responses.

Abstract: In part, the invention relates to systems, methods, and devices that store and retrieve information associated with an imaging probe such as an ultrasound probe, an optical coherence tomography probe, a multimodal probe and other probes. The information that is stored relates to one or more measurable properties for a specific imaging probe. Thus, when each probe is manufactured there can be variations in its length, brightness, angular alignment of its constituent elements, and various other probe specific measurements. In turn, these measurements can be used to calibrate or otherwise use a given probe with a system that collects, stores, or otherwise processes information collected using each probe.

Abstract: A method for establishing a data packet exchange communication session that allows the exchange of data packets between an originating client and a destination client in a data network having a client-server arrangement is provided. An originating client transmits communications session request data message to a communications management server via a first temporary signaling communications path. The communications session request data message contains at least a unique network address of a destination client. The communications management server, upon determining that said originating client is residing behind a first network firewall, determining whether said first network firewall will allow exchange of data packets between said originating client and any other client not residing behind said first network firewall.
