Title: Process for making dicyclopentadiene polyetherester resins
Inventor: KLANG JEFFREY A
IPC: C08G63/676
Filed: 1998-08-26
Abstract: A low-cost way to modulate the reactivity and acid number of polyetherester thermoset resins is disclosed. "Beginning" and "end" methods for making dicyclopentadiene (DCPD)-modified polyetherester resins are described. The "beginning" method comprises first heating a polyether, DCPD, a diol, an insertion catalyst, and a carboxylic acid derivative to produce a mixture that contains the polyether and a DCPD-diol diester adduct. Increasing the temperature causes insertion of the DCPD-diol diester into the polyether to give a DCPD polyetherester resin. The "end" method reacts a polyetherester resin made by insertion with DCPD to give a DCPD polyetherester resin.  Compared with DCPD polyester resins, those of the invention give more flexible thermosets. Compared with unmodified polyetherester resins, the DCPD  polyetherester resins offer formulators more control over curing, which eliminates mold distortion and shrinking or cracking of thermoset parts.  Thermosets from blends of the subject resins and DCPD polyester resins show synergistic property improvements compared with thermosets from either resin alone.

Title: Method and apparatus for facilitating computer network transactions
Inventor: WOLFF ERIC L
IPC: G06Q30/02
Filed: 1998-10-23
Abstract: A method and apparatus for facilitating computer network transactions are disclosed herein. The computer network connects a host node and at least one user node. The host node has access to a database including records having predetermined contents, each record associated with a unique identification indicia. Each user node includes a display for displaying an icon and an input device for selecting the icon. The icon is typically an advertising banner having graphics related to an advertised product or service. The icon has embedded therein the network address of the host node, and the indicia for a record associated with the advertised product or service. The icon displayed on one user node is selected by actuating the respective input device (e.g., a mouse). The host network address embedded in the selected icon is used to contact the host node. Then, the record associated with the selected icon is retrieved by searching the database using the indicia embedded in the selected icon as a pointer. An input form is dynamically generated which includes at least one input field requesting data from the user, a portion of the input form depending on the contents of the retrieved record. The input form is presented on the display of the one user node. After entry, at least a minimum set of the requested data is communicated to the host node over the network.  The requested data may be validated, with the user requested to provide any needed corrections. Once the data is valid, a confirmation form is generated based on the requested data and is displayed to the user. If the user acknowledges the confirmation form, an acknowledgment form is generated and displayed. The acknowledgment form may include a second cascaded icon.

Abstract: The present invention includes systems and methods for monitoring the spooling area of a rotatable reel for winding or unwinding an elongated material, for example, a cable. The monitoring system has a detector for sensing the presence and position of a cable surface or object or operator positioned between the detector and the reel. The detector can control rotation of the reel directly, or send a position signal to a computer where the position signal indicates the detected presence and/or position. The computer can have a memory and/or a processor for respectively storing and analyzing the position signal.      The computer is operative to compare the position signal to previously received position signals to determine a condition, for example, the amount of cable on the reel, the presence of any object, and/or the existence of a safety-threatening condition. The computer can generate an output signal for use in, for example, controlling the reel speed and/or torque, or the application of brakes.

Abstract: A thermal interface material (A) transfers heat from a heat source (12), such as a microprocessor, to a heat sink (14) for maintaining the microprocessor at a safe operating temperature. The interface material includes thermally conductive filler particles dispersed in a phase change material. The phase change material softens and flows at the operating temperature of the heat source, thereby providing good thermal contact with uneven surfaces of the heat source and heat sink, without excessive exudation and loss of the interface material. The phase change material includes a polymer component, such as an elastomer, and a melting point component, which adjusts the softening temperature of the phase change material to the operating temperature of the heat source.

Filed: 1998-12-14
Abstract: The disclosed invention relates to an improved electrotransport device. The improvement relates to a membrane assembly including a low porosity membrane adhered or sealed to one or two high porosity membranes. The high porosity membranes protect the low porosity membrane from being damaged by components or contaminates on the body surface and/or in the drug reservoir which can lead to undesirable passive flux and/or insufficient iontophoretic flux. As a result, the electrotransport device having the membrane assembly more reliably, precisely, and accurately delivers drug and/or therapeutic agent through the body surface by electrotransport.

Abstract: Integrated optoelectronic devices having pop-up mirrors therein include a substrate (e.g., SOI substrate) having an opening therein that extends at least partially therethrough. A mirror having near diffraction-limited quality is also provided in the opening and is mechanically coupled to the substrate by a hinge so that the mirror can be rotated from a closed position to an open position. The mirror may be formed from a monocrystalline silicon mirror backing layer having a thickness greater than about 10 µm and an optically reflective mirror surface on the backing layer. The mirror surface may comprise gold or aluminum and may be applied to the backing layer using an evaporation or sputtering technique. This monocrystalline silicon mirror backing layer is highly resistant to warping or other distortions caused when stresses are applied to it. The hinge also preferably comprises a polycrystalline silicon hinge that provides a mechanical and an electrical connection to the substrate. A layer of metal such as nickel is also provided on a back surface of the mirror backing layer so that an application of a sufficiently strong magnetic field to the opening will induce a force on the layer of metal that operates to pull the mirror backing layer to an upright position. An electrostatic polysilicon clamp electrode is also provided on the monocrystalline silicon mirror backing layer. This clamp electrode can be used advantageously to clamp the mirror in a closed position even if a sufficiently strong magnetic field is applied to the opening. Thus, a substrate having a plurality of individually controllable reflective microstructures (e.g., "pop-up" mirrors) can be provided.
