A method for associating related electronic messages in computer storage. A first transportable application is created and stored. User input requesting creation of a link from the first transportable application to another transportable application is received. User input that selects a second transportable application from among a plurality of previously created transportable applications is received. A link from the first transportable application to the second transportable application is created and stored. As a result, transportable application may be inter-related in complex message webs. The message webs may also be inter-related in message web rings. Links may be generated manually or automatically, based on context, workflow processes, or other known relationships among applications. Recipient lists and data may propagate among fields of linked transportable applications, directly or according to abstract business rules. Further, multiple-part electronic messages are disclosed. A graphical user interface of an electronic messaging system displays a message in the form of one or more header portions and one or more body portions. Each of the body portions has a selection region. While one body portion is visible at a given time, all the selection regions are continuously visible in the user interface to facilitate selection of any of the body portions at a particular time. Selecting a selection region of a non-displayed body portion causes a server to generate a refreshed user interface that includes the entirety of the selected body portion, and that hides the previously viewed body portion. As a result, a large amount of associated information may be combined in a single message in a way that is clearly organized and easily accessible.

A device is provided for compression of objects such as parts of the body. The device has the form of a band that can be shaped like a sleeve, wrap or garment that is sized to encircle the body part or other compressible object and having a component or components made of an elastic material.

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 normal force gradient / shear force sensor device and measurement method for measuring internal stresses in tissues of a person supported by a chair or bed includes a planar matrix array of peripheral normal force sensors radially spaced from central shear force sensors, comprising an electrically conductive disk located within a circular opening bordered by circumferentially spaced apart electrodes. The disk and electrodes are located between upper and lower cover sheets made of a stretchable material such as polyurethane; one cover sheet is adhered to the disk and the other sheet is adhered to a support sheet for the electrodes. Motion between the cover sheets in response to shear forces exerted on the array causes the disk to press more or less tightly against the electrodes varying electrical conductance between the disk and electrodes proportionally to the magnitude and direction of the shear force. Each normal force sensor includes an electrically conductive film pressed between row and column conductors. Measurements of conductance values of pairs of sensor, which vary proportionally to normal forces exerted on the sensor, are used to calculate a gradient vector of normal forces exerted by a body part on the sensor array, which is combined with the shear force vectors in an algorithm to calculate internal reaction shear forces, e.g., on flesh near a bony prominence.
