Abstract: A characterization method for a network address translation (NAT) device by an internal computer behind the NAT device includes creating a plurality of sockets; binding the plurality of sockets, respectively, to a plurality of ports; transmitting a plurality of STUN requests in user datagram protocol (UDP) packets to a plurality of STUN servers, wherein each STUN request is associated with one of the sockets; determining that the NAT device does not support UDP packets if responses are not received from the STUN servers; and determining a set of NAT characteristics of the NAT device if a response is received from each of the STUN servers.

Abstract: A system and method for seamlessly switching between various bus interfaces on a device, regardless of the application using the device. The change of the bus interface being used is completely transparent to the application using the device. A system in accordance with an embodiment of the present invention creates a Physical Device Object (PDO) that is unique for each device, regardless of which bus interface is used by the device. An application using that is essentially linked to this unique PDO. In one embodiment, an exhaustive list of various devices connected to the different bus interfaces is created. This is done by creating a bridge between the enumerators for the various buses and a class enumerator.

Abstract: A power management component in a computer system includes an imaging device operatively connected to a computer. When the computer has entered a low power state, the imaging device can continue to operate to detect motion in its field of view. When “enough” motion is detected, the imaging device can signal the computer in a manner as to transition the computer to a full power state. In another aspect of the present invention, the imaging device can determine that there has been insufficient motion for a predetermined period of time and initiate a transition of the computer to a low power state.

Abstract: A method and a system for dynamically detecting and correcting anomalous pixels in the raw data taken from an image sensor array such as a CCD or a CMOS sensor array, thus allowing the use of dumb cameras to capture digital images for subsequent use by an intelligent host—such as being displayed on a computer monitor. This invention uses software algorithms running on an intelligent host processor to dynamically correct the anomalous pixels in the raw data taken from an image sensor array typical of those in a digital still or a video camera. Using the combination of a dumb camera which provides raw data to an intelligent host, which does all the subsequent image processing, the system works by scanning an image frame for pixels that vary more than a specified amount in their brightness value from their neighboring pixels and designating those as defective pixels. The location and frequency of the photosites sending the defective pixels are stored in a statistical database in the computer's memory.
