A system whereby a magnetic tip attached to a surgical tool is detected, displayed and influenced positionally so as to allow diagnostic and therapeutic procedures to be performed rapidly, accurately, simply, and intuitively is described. The tools that can be so equipped include catheters, guidewires, and secondary tools such as lasers and balloons, in addition biopsy needles, endoscopy probes, and similar devices. The magnetic tip allows the position and orientation of the tip to be determined without the use of x-rays by analyzing a magnetic field. The magnetic tip further allows the tool tip to be pulled, pushed, turned, and forcefully held in the desired position by applying an appropriate magnetic field external to the patient's body. A Virtual Tip serves as an operator control. Movement of the operator control produces corresponding movement of the magnetic tip inside the patient's body. Additionally, the control provides tactile feedback to the operator's hand in the appropriate axis or axes if the magnetic tip encounters an obstacle. The output of the control combined with the magnetic tip position and orientation feedback allows a servo system to control the external magnetic field by pulse width modulating the positioning electromagnet. Data concerning the dynamic position of a moving body part such as a beating heart offsets the servo systems response in such a way that the magnetic tip, and hence the secondary tool is caused to move in unison with the moving body part. The tip position and orientation information and the dynamic body part position information are also utilized to provide a display that allows three dimensional viewing of the magnetic tip position and orientation relative to the body part.

A Catheter Guidance Control and Imaging (CGCI) system whereby a magnetic tip attached to a surgical tool is detected, displayed and influenced positionally so as to allow diagnostic and therapeutic procedures to be performed is described. The tools that can be so equipped include catheters, guidewires, and secondary tools such as lasers and balloons. The magnetic tip performs two functions. First, it allows the position and orientation of the tip to be determined by using a radar system such as, for example, a radar range finder or radar imaging system. Incorporating the radar system allows the CGCI apparatus to detect accurately the position, orientation and rotation of the surgical tool embedded in a patient during surgery. In one embodiment, the image generated by the radar is displayed with the operating room imagery equipment such as, for example, X-ray, Fluoroscopy, Ultrasound, MRI, CAT-Scan, PET-Scan, etc. In one embodiment, the image is synchronized with the aid of fiduciary markers located by a 6-Degrees of Freedom (6-DOF) sensor. The CGCI apparatus combined with the radar and the 6-DOF sensor allows the tool tip to be pulled, pushed, turned, and forcefully held in the desired position by applying an appropriate magnetic field external to the patient's body. A virtual representation of the magnetic tip serves as an operator control. This control possesses a one-to-one positional relationship with the magnetic tip inside the patient's body. Additionally, this control provides tactile feedback to the operator's hands in the appropriate axis or axes if the magnetic tip encounters an obstacle. The output of this control combined with the magnetic tip position and orientation feedback allows a servo system to control the external magnetic field.

A reduced rank adaptive digital filtering method is described for a received signal consisting of a sequence of N×1 received vectors. Each received vector is formed from a group of N successive samples. D+1 basis vectors are generated where D is less than N and the dimension of a desired reduced rank subspace. Each successive basis vector is generated by multiplying an immediate preceding basis vector by the covariance matrix for the sequence of received sample vectors and the first basis vector is formed from a given or estimated steering vector. D filter coefficients are generated from correlations between pairs of basis vectors. The adaptive digital filter of the present invention achieves near optimal rank performance with substantially fewer training symbols than heretofore possible.

A system and method of guiding a remote aerial vehicle toward a designated target includes an imaging sensor which generates sequential video images of the target area from the remote aerial vehicle and transmits the images to a control center via the video portion of a communications data link. The control center receives and displays the plurality of video images on a video display. An image selection signal is generated at the control center and transmitted to the remote aerial vehicle for commanding the imaging sensor to continuously transmit one of the sequential video images. A target designation signal, corresponding to the azimuth and elevation of the desired target on the continuously displayed video image, is generated and transmitted via a command portion of the data link to the remote aerial vehicle. The target designation signal is processed and an updated target position is computed to compensate for time delays. A tracker tracks the updated target position to thereby guide the remote aerial vehicle toward the designated target. The video images and the target designation signal may be transmitted at low bandwidth frequencies to a satellite and relayed to the control center and the remote aerial vehicle respectively.

The NaPier tube is a self-expanding port-access tube for insertion into body passages. A NaPier tube is typically used with an endoscope disposed within the lumen of an unactivated tube to enable visual navigation to place the tube in a passage. A NaPier tube comprises a shape-memory element, wall material, and a removable sheath. A tear-away, removable sheath maintains the shape-memory element in a compressed state. Upon placement of the distal end of a NaPier tube in the target location in a passage, the sheath is ruptured and removed through the port and the shape-memory element expands to its memorized geometries. Embodiments of the NaPier tube are adapted by length and memorized dimensions for endotracheal intubation and for port-access procedures, such as endoscopic surgery.

A method and apparatus for providing therapeutic pulse laser treatment. The treatment method includes delivering more than one therapeutic laser light protocol from a hand held therapeutic laser device according to a preprogrammed schedule. At one or more select times during the preprogrammed schedule, the hand held therapeutic laser device will produce audio output. The audio output provides information to the user and directs him or her to execute a step in the overall treatment plan. For example, the audio output may signal to the user that it is necessary to make a change in or between treatment protocols, move the laser device, pause treatment, or otherwise control the delivery of therapeutic laser light. The ability of a relatively untrained user to implement the method may be enhanced if the audio output is delivered as synthetic speech output.

Described herein is a process and system for constructing three-dimensional (3D) representations of buildings. The 3D representations of buildings are semantic models that include roof nodes, roof edges, as well as roof faces with associated properties (e.g., pitch, azimuth). The system receives a 2D representation such as a roof outline including nodes connected by edges and associated data such as a height value, a pitch value, an independent structure, or a dependent structure. The system determines height values where a building structure changes. The system propagates a wavefront representing a cross-section of the building to the height values to generate 3D model edges. The 3D representation is generated based on the 3D model edges. The system can create 3D representations of buildings including roof structures of arbitrary complexity and can create representations of dependent roof structures such as dormers.
