摘要： A method and apparatus are presented for messaging within a plurality of nodes 100, wherein each node 100 includes a processor 208, a memory 210 connected with the processor 208, and a directional communication interface 204 connected with the processor 208. The nodes 100 are operative for receiving a message including an address code with a relative target address of an intended recipient node 106; for processing the address code to determine if the current node 100 is the intended recipient node 106; for modifying the message based on the direction from which the message was received and is to be transmitted; and for re-transmitting the message including a modified address code. The nodes 100 each repeat these actions to propagate a message along multiple paths until the message along multiple paths until the message reaches a desired recipient, thereby providing path redundancy without the need for the use of unique node 100 identities or locations.

摘要： High-speed, low capacitance heterojunction bipolar transistors (HBTs) and a method for their fabrication are disclosed. The devices are fabricated by a manufacturable process which moves patterning and deposition of the base post (112) up versus the current manufacturing process, thus permitting fabrication of a smaller base post (112) and base metal contact (104) and reducing the base collector capacitance.

摘要： A method of making a micro electro-mechanical switch or tunneling sensor. A cantilevered beamstructure and a mating structure are defined on a first substrate or wafer; and at least one contactstructure and a mating structure are defined on a second substrate or wafer, the mating structureon the second substrate or wafer being of a complementary shape to the mating structure on thefirst substrate or wafer. A bonding layer, preferably a eutectic bonding layer, is provided on at least one of the mating structures. The mating structure of the first substrate is moved into aconfronting relationship with the mating structure of the second substrate or wafer. Pressure isapplied between the two substrates so as to cause a bond to occur between the two mating structures at the bonding or eutectic layer. Then the first substrate or wafer is removed to free thecantilevered beam structure for movement relative to the second substrate or wafer.

Cantilevered beamstructures for at least two orthogonally arranged sensors and associated mating structures aredefined on a first substrate or wafer, the at least two orthogonally arranged sensors havingorthogonal directions of sensor sensitivity. A resonator structure of at least a third sensor is alsodefined, the third sensor being sensitive in a third direction orthogonal to the orthogonal directions of sensor sensitivity of the two orthogonally arranged sensors and the resonatorstructure having a mating structure thereon. Contact structures for at least two orthogonallyarranged sensors are formed together with mating structures on a second substrate or wafer, themating structures on the second substrate or wafer being of a complementary shape to the matingstructures on the first substrate or wafer. The mating structures of the first substrate aredisposed in a confronting relationship with the mating structures of the second substrate orwafer. A eutectic bonding layer associated with one of the mating structures facilitates bondingbetween the respective mating structures. At least a portion of the first substrate or wafer is removed to release the cantilevered beam structures and the resonator structure.

摘要： A method and apparatus of substantially canceling the effects of temperature on the electrical performance of Field Effect Transistor (FET) integrated circuits (IC's) by exploiting a subtle feature of an epitaxial resistor implemented in an FET process. Specifically, the invention takes advantage of two constituent epitaxial resistor components having resistances that vary monotonically in opposite directions as functions of temperature. The essential components include: a plurality of ohmic contacts (100), and an isolated semi-conductor channel (102) residing in a layered semiconductor. The resistance of the epitaxial resistor R of the invention is comprised of an aggregate of resistances (FIG. 1c). The invention includes a method for selecting the geometry of such an epitaxial resistor to give it either temperature invariance or a specific, useful functional temperature dependence.

摘要： A polarization converting surface for reflecting impinging radio frequency waves. The surface includes a ground plane and a plurality of elements disposed in an array a distance from the ground plane. Each element is preferably connected to the ground plane by a conductor, the array of elements having two major axes associated therewith. The elements have a first bandwidth corresponding to a first range of frequencies were a first reflection phase falls between -π/2 and +π/2 in a first one of said two major axes and a second bandwidth corresponding to a second range of frequencies where a second reflection phase falls between -π/2 and +π/2 in a second one of said two major axes. The first and second bandwidths partially overlap and preferably an upper half of one of the bandwidths overlies a lower half of the other one of the bandwidths.

摘要： A data flow system, where a source (100) transmits a reservation packet to an ingress element (102). The ingress element (102) polices incoming message traffic and collects data flow information. Quality of service differentiation is realized by marking data packet of different data flows. The ingress element (102) registers the reservation packet and forwards the request to a core router (106). The core router (106) evaluates the service level required, and available resources. Based on this evaluation the core router (106) will reject, accept, or modify the received message, indicate the price for the requested level of service, and forward the reservation packet. The process is repeated until the reservation packet reaches the destination (110), which sends a feedback message to the source (100) indicating the result of the reservation packet. After establishing a reservation, source 100 transmits periodic control messages and collects information regarding resource availability, and the flow path.
