Title: Cutting tissue with electrosurgically deployed electrodes
Inventor: EGGERS ERIC A
IPC: A61B18/12
Filed: 2000-10-10
Abstract: Method, system and apparatus for carrying out accurate electrosurgical cutting. A thin resilient electrode (54) is utilized at the forward end region (50) of an instrument which is deployable from a longitudinally disposed slot positioned rearwardly from the tip of the instrument. Lateral sides of the slot extend between a forward location adjacent the tip and a rearward location. The electrode is deployed by urging it forwardly in compression to form an arch profile supported by the abutting slot sides. Electrosurgically excitable with a cutting output, the electrode may carry out a cutting action both during its deployment and retraction into the noted slot. This permits a pivoting maneuver effective for circumscribing a volume of targeted tissue.

Title: Thermochromic laminates and methods for controlling the temperature of a structure
Inventor: KHALDI WALEED
IPC: B32B7/023
Filed: 2000-09-29
Abstract: Thermochromic laminates, which predictably vary their ability to absorb or reflect electromagnetic radiation, are provided. Laminates of the invention advantageously possess temperature trigger zones, that is, points or ranges of temperature, which function to decrease or increase the amount of electromagnetic energy, and particularly energy in the UV, infrared and visible ranges, that is reflected from the laminate, or absorbed as heat by the laminate and transmitted to an underlying structure. Laminates of the present invention can be provided in a variety of colors and temperature trigger points or ranges, and require no input of external energy except that of the impinging radiation. Laminates of the invention advantageously can be used in methods alone or combined with other materials such as roofing, siding, heat exchangers and other heat transfer materials and are therefore useful to control the temperature of an underlying structure or object.

Abstract: A computer system provides authenticated access for a client computer (18) over an insecure, public network (26) to one of a plurality of destination servers (28) on private, secure network, through the use of a client-side X.509 digital certificate.  A firewall (32) is disposed between the insecure, public network (26) and the private network. A demilitarized zone (DMZ) proxy server (34) intercepts messages destined for the destination servers (28), and forwards the intercepted messages through the firewall (32) to a gateway (38) on the private network. The gateway (38) is configured to create a cookie, based on the selection of one of several applications (30) available on the private network. The cookie contains an identifier sufficient to identify the destination server (28) corresponding to the selected application (30). Messages from the client computer include the cookie. The gateway (38) processes the cookie and appends the identifier on a destination URL portion of the messages for routing. An alternate computer system authenticates a user of a remote client computer on the insecure network site (26) of the firewall (32) using a user identification and password.

Base stations are provided with radio interfaces and are each connected to one of the controllers. A second path is established in a transfer procedure comprising the transmission of control data from the first to a second master controller, and the suppression of the first path. The infrastructure comprises a network core, and radio network controllers linked to the core of the network. Base stations are provided with radio interfaces and are each connected to one of the controllers. Digital information is transmitted on a first communication path in circuit mode between the core of the network and the terminal, passing through a first master controller, then on a second communication path in circuit mode between the core of the network and the terminal, passing through a second master controller. The second path is established in a transfer procedure comprising the transmission of control data from the first to the second master controller, and the suppression of the first path. This control data is representative of a current value of a sequence number used to number the information, incremented at regular intervals, and a shift between this sequence number and a time reference available to the second controller.

Inventor: DOMMANN ALEX
IPC: B22D27/20
Filed: 2001-06-11
Abstract: A manufacturing process for casting amorphous metallic parts separates the filling and quenching steps of the casting process in time. The mold is heated to an elevated casting temperature at which the metallic alloy has high fluidity. The alloy fills the mold at the casting temperature, thereby enabling the alloy to effectively fill the spaces of the mold. The mold and the alloy are then quenched together, the quenching occurring before the onset of crystallization in the alloy. With this process, compared to conventional techniques, amorphous metallic parts with higher aspect ratios can be prepared.
