摘要:
Continuous recording multichannel disk-based data logging apparatus. The apparatus includes a plurality of disk drives and an interface including a plurality of parallel inputs. The interface is responsive to data at the inputs to write the data on an active plurality of the disk drives, at least one disk drive being idle. The interface is responsive to a user request for data on one of the active disk drives to substitute an idle disk drive into the active plurality in place of that one, to read the requested data, and to cause that one to become idle.

Methods and systems are provided that prevent buffer overflow in multibus systems. In one aspect, a method for controlling the flow of data in a multibus system includes, for each node having an associated broadcast bus in the multibus system, generating status information regarding available data storage space of each receive buffer of the node. The method includes broadcasting the status information to the other nodes connected to the broadcast bus and collecting status information regarding the available storage space of receive buffers of the other nodes connected to the broadcast bus. The method also includes determining whether or not to send data from the node to at least one of the other nodes over the broadcast bus based on the collected status information.

Embodiments of the present invention are directed to optoelectronic network switches. In one embodiment, an optoelectronic switch includes a set of roughly parallel input waveguides and a set of roughly parallel output waveguides positioned roughly perpendicular to the input waveguides. Each of the output waveguides crosses the set of input waveguides. The optoelectronic switch includes at least one switch element configured to switch one or more optical signals transmitted on one or more input waveguides onto one or more crossing output waveguides.

Various embodiments of the present invention relate to systems for reducing the amount of power consumed in temperature tuning resonator-based transmitters and receivers. In one aspect, a system comprises an array of resonators (801-806) disposed adjacent to a waveguide (646) and a heating element (808). The heating element is operated to thermally tune the array of resonators so that each resonator in a subset of the array of resonators is in resonance with a wavelength of light traveling in the waveguide.

Tunable resonator systems and methods for tuning resonator systems are disclosed. In one aspect, a resonator system includes an array of resonators disposed adjacent to a waveguide, at least one temperature sensor located adjacent to the array of resonators, and a resonator control electronically connected to the at least one temperature sensor. Each resonator has a resonance frequency in a resonator frequency comb and channels with frequencies in a channel frequency comb are transmitted in the waveguide. Resonance frequencies in the resonator frequency comb are to be adjusted in response to ambient temperature changes detected by the at least one temperature sensors to align the resonance frequency comb with the channel frequency comb.

Various embodiments of the present invention are directed to stacked memory modules. In one embodiment of the present invention, a memory module comprises at least one memory-controller layer stacked with at least one memory layer. Fine pitched through vias (e.g., through silicon vias) extend approximately perpendicular to a surface of the at least one memory controller through the stack providing electronic communication between the at least one memory controller and the at least one memory layers. Additionally, the memory-controller layer includes at least one external interface configured to transmit data to and from the memory module. Furthermore, the memory module can include an optical layer. The optical layer can be included in the stack and has a bus waveguide to transmit data to and from the at least one memory controller. The external interface can be an optical external interface which interfaces with the optical layer.
