Abstract: A device and method is provided that includes a window for coupling a signal between cavities of a device or between cavities of different devices. A wall or microstructure is formed on a surface and defines a cavity. The window is formed in the wall and comprises at least a portion of the wall and is electrically conductive. The cavity can be sized to resonate at various frequencies within the terahertz portion of the electromagnetic spectrum and generate an electromagnetic wave to carry the signal. The window allows surface currents to flow without disruption on the inside surface of the cavity.

Abstract: In an optical switch, a set of coherent electromagnetic radiation is selectively delayed and recombined to produce constructively or destructively combined radiation. When the radiation is constructively combined, a signal is transmitted out of the switch to a remote receiver. When the radiation is destructively combined, a signal is not transmitted out of the switch to a remote receiver.

Abstract: In one embodiment, a memory controller for a node in a multi-node computer system comprises logic and a control unit. The logic is configured to determine if an address corresponding to a request received by the memory controller on an intranode interconnect is a remote address or a local address. A first portion of the memory in the node is allocated to store copies of remote data and a remaining portion stores local data. The control unit is configured to write writeback data to a location in the first portion. The writeback data corresponds to a writeback request from the intranode interconnect that has an associated remote address detected by the logic. The control unit is configured to determine the location responsive to the associated remote address and one or more indicators that identify the first portion in the memory.

Abstract: A device includes a waveguide layer formed on a substrate. An ultra-small resonant structure emits electromagnetic radiation (EMR) in the waveguide layer. One or more circuits are formed on the waveguide layer and each operatively connected thereto to receive the EMR emitted by the ultra-small resonant structure. The waveguide layer may be transparent at wavelengths corresponding to wavelengths of the EMR emitted by the ultra-small resonant structure. The EMR may be visible light and may encode a data signal such as a clock signal.

Abstract: A nano-resonating structure constructed and adapted to include additional ultra-small structures that can be formed with reflective surfaces. By positioning such ultra-small structures adjacent ultra-small resonant structures the light or other EMR being produced by the ultra-small resonant structures when excited can be reflected in multiple directions. This permits the light or EMR out put to be viewed and used in multiple directions.

A connector is constructed and adapted to receive emitted EMR from said at least one of said chips having transmission circuitry and further constructed and adapted to provide data in said EMR emitted by said at least one of said chips to receiver circuitry of at least some others of said plurality of chips.

Abstract: An electronic transmitter or receiver employing electromagnetic radiation as a coded signal carrier is described. In the transmitter, the electromagnetic radiation is emitted from ultra-small resonant structures when an electron beam passes proximate the structures. In the receiver, the electron beam passes near ultra-small resonant structures and is altered in path or velocity by the effect of the electromagnetic radiation on structures. The electron beam is accelerated to an appropriate current density without the use of a high power supply. Instead, a sequence of low power levels is supplied to a sequence of anodes in the electron beam path. The electron beam is thereby accelerated to a desired current density appropriate for the transmitter or receiver application without the need for a high-level power source.

Abstract: In a laser system, a set of substantially coherent electromagnetic radiation is applied as an input to a Raman laser. The Raman laser may be fabricated on the same integrated circuit as the source of the substantially coherent electromagnetic radiation or may be fabricated on a different integrated circuit as the source of the substantially coherent electromagnetic radiation.

Abstract: When using micro-resonant structures, it is possible to use the same source of charged particles to cause multiple resonant structures to emit electromagnetic radiation. This reduces the number of sources that are required for multi-element configurations, such as displays with plural rows (or columns) of pixels. In one such embodiment, at least one deflector is placed in between first and second resonant structures. After the beam passes by at least a portion of the first resonant structure, it is directed to a path such that it can be directed towards the second resonant structure. The amount of deflection needed to direct the beam toward the second resonant structure is based on the amount of deflection, if any, that the beam underwent as it passed by the first resonant structure. This process can be repeated in series as necessary to produce a set of resonant structures in series.

Abstract: A lock-free implementation of an ordered data structure allows updating of the data structure without disturbing the ordering relied upon for accessing the data structure. After searching and finding an element in a data structure in accordance with an update operation (i.e., an insert operation or a remove operation), values are successively copied to shift the values either up or down the data structure. If an insert operation is being performed, then the new value is eventually inserted to overwrite a duplicate value in the data structure. If a delete operation is being performed, then a value is shifted over the value to be deleted.

Abstract: A method, and associated system, for performing distributed computing. The method includes linking a user node to a communications network including a processor with a processing capacity, memory, and a browser for viewing documents provided over the network. The method includes operating the browser to request a document from a server linked to the network and then receiving a host document or host web page. The browser views the host document and loads a distributed application that requests work from the server. The user node receives work units from a distributed computing project associated with the distributed application. The distributed application is run by the processor using excess capacity to process the work unit to generate a result. The method determines if the browser is still viewing the host document and the processor is available. The browser may be replaced with a user application that provides distributed computing.

Abstract: A method and apparatus for facilitating the determination of a status of an asynchronous memory (e.g., how full or empty the memory is). A write pointer to the memory is maintained in a first clock domain; a read pointer is maintained in a second clock domain. The pointers are maintained in a non-binary code format promoting minimum bit transitions as the pointers increment (e.g., Gray code). Each pointer is transmitted to the other clock domain through synchronizers. Each synchronizer comprises multiple sets of D flip-flops. In each clock domain, the write pointer and read pointer values are converted to mathematically useful formats (e.g., binary), and their difference is calculated. The difference indicates how much space in the memory is or is not used, and may be compared to a non-zero threshold.

Abstract: A method for determining misalignment between two semiconductor dies is described in which signals are transmitted through a first subset of an array of proximity connectors that are proximate to a surface of one of the semiconductor dies and received through a second subset of an array of proximity connectors that are proximate to a surface of the other semiconductor die. A spatial beat frequency is determined from the received signals. This spatial beat frequency corresponds to misalignment-induced aliasing of spatial frequencies associated with the first subset of the array of proximity connectors and the second subset of the array of proximity connectors. The misalignment is then determined using the spatial beat frequency.

Abstract: One embodiment of the present invention provides a system that facilitates aligning a first signal with a second signal in a manner that optimizes a correlation between the first signal and the second signal. The system starts by receiving a set of signals, including the first signal and the second signal. The system then determines a correlation between the first signal and the second signal. Next, the system adjusts an alignment between the first signal and again determines a correlation between the first signal and the second signal. If the correlation is greater with the alignment adjustment, the system adjusts the alignment between the first signal and the second signal. This process of adjusting the alignment is repeated for different alignments to find an optimal alignment. Hence, the present invention operates effectively for signal sources which may be independently speeding up and slowing down with respect to each other while under surveillance.

Abstract: One embodiment of the present invention provides a system that enhances reliability, availability and serviceability in a computer system by replacing a signal from a failed sensor with an estimated signal derived from correlations with other instrumentation signals in the computer system. During operation, the system determines whether a sensor has failed in the computer system while the computer system is operating. If so, the system uses an estimated signal for the failed sensor in place of the actual signal from the failed sensor during subsequent operation of the computer system, wherein the estimated signal is derived from correlations with other instrumentation signals in the computer system. This allows the computer system to continue operating without the failed sensor.
