Title: Software analysis system having an apparatus for selectively collecting analysis data from a target system executing software instrumented with tag statements and method for use thereof
Inventor: TINKER JEFFREY LEE
IPC: G06F11/36
Filed: 2001-01-26
Abstract: A software analysis system having a filter for selectively collecting tags generated by a target system during execution of a software program under analysis in accordance to a programmable filtering criteria. The system includes a decoder for decoding the tag type of the tags captured from the data bus of the target system, and a comparator for comparing the tag types to the programmable filtering criteria to determine whether the tag should be collected. The programmable filtering criteria may be programmed by collecting filter tags from the target system, or directly programmed by a software developer using a filtering user interface. The programmable filtering criteria is implemented by a filter table that stores a flag associated with each tag type. The flag is indicative of whether tag data of a respective tag type should be collected. Tag data of the tag types meeting the programmable filtering criteria have timestamp information appended to the tag data and are collected in a tag buffer.

Abstract: A system for manipulating a heart during cardiac surgery permits coronary surgery on a beating heart while maintaining cardiac output unabated and uninterrupted.   Circumflex coronary artery surgery can be performed using the system. The system locates a suspension head near the apical region of the heart. A frame is positioned within the patient's thoracic region and moves with the patient, and a surgical target immobilizer can be used to assist in the movement of the heart if desired. A special suction cup is used which accommodates movement of the heart and the myocardium while also preventing heart tissue from interrupting the suction being applied to the heart. One form of the system can be used in minimally invasive surgery.

Inventor: SUREK STEVEN A
IPC: H04B10/278
Filed: 2001-02-05
Abstract: In an optical telecommunications network in accordance with the principles of the present invention, a link connection undergoes an automatic port recognition process, whereby the port binding information for the link is detected, recorded and shared with the network elements connected by the link, before the link is used to transmit bearer traffic. One of a group of optical network elements that communicate through an out of band channel, such as a LAN, is "elected" a network element leader. After election, the leader network element coordinates the port discovery process; requests for port "recognition", responses to requests, and other messages are passed through the network element leader on the out of band channel from one non-leader network element to another. Once the recognition process is set up through the leader network element, an optical test signal is transmitted along the link in question from the recognition requesting network element to all other network elements in the network. The receiving network elements monitor the power level at each of their "inactive" ports and the inactive port at which an increased energy level is detected is determined to be the port attached to the link in question.

Abstract: The technique of amplifier sharing is implemented in a system designed to accommodate transmit diversity. In one embodiment of the invention, the amplifiers (670 and 675) are shared 1) to amplify a first and a second diversity- encoded signal, each of which represents the information of a first signal that is to be transmitted using transmit diversity, and 2) to amplify a second signal t o be transmitted without using transmit diversity. The first and second diversity - encoded signals are used to form a first and a second composite signal. Each composi te signal is amplified in a different one of two power amplifiers (670 and 675) . Each amplified composite signal is then used to form an amplified first diversity - encoded signal and an amplified second diversity-encoded signal. The first and secon d composite signals can also be formed using the second signal. Each composite signal is then amplified in a different one of the two power amplifiers (670  and 675) and the two amplified composite signals are used to form an amplified second signal. In another embodiment of the invention, the first and second composi te signals can be formed in the digital domain. Each composite signal is digitally pre- distorted and then modulated onto a transmission frequency signal, such as a n RF signal. Each pre-distorted composite signal is then amplified in the respective amplifier (670 and 675).

IPC: H01R4/22
Filed: 2001-11-22
Abstract: An improved twist-on wire connector that permits the user to form the junction ends of wire leads into a low resistance electrical connection with the twist-on wire connector including a self adhering lubricant located along a portion of the interior of the twist-on wire connector. In one embodiment the wires are drawn into the housing by a spiral thread through the twisting action of the wires with respect to housing. As the wires are drawn into the spiral thread, the torque applied to the wires increases until the wires can no longer be hand twisted into the wire connector. Once the wires are drawn into contact with the lubricant the torque resistance, which is a result of frictional resistance between the wires and the spiral thread, decreases while the radial compressive forces between the wires and the spiral thread are substantially unaffected. Consequently, the rate of torsonial resistance decreases allowing the wires to be brought into further electrical contact along a greater length through only hand tightening while at the same time the radially compressive forces on the wires are greater thus ensuring a low resistance electrical contact that remains stable over an extending period of time. Because only a small amount of self-adhering lubricant is needed within the wire connector to provide an enhanced low-resistance electrical connection problems of the self-adhering lubricant accidentally coming into contact with the exterior housing of other twist-on wire connectors is minimized even if not caps are used on the twist-on wire connectors.
