  • Patent number: 11381061
    Abstract: A system for servicing cable includes a field-end assembly and a live-end assembly, each mounted on a support structure having at least one drive mechanism operable to cause relative linear movement between the field-end assembly and the live-end assembly. A drilling-and-shorting assembly can create a short circuit in a field-end of the cable, and a continuity tester can test the integrity of the short-circuit. The field end of the cable can then be ejected from the system, and an end-cap-cradle assembly can position an end cap on a live end of an electrical cable and test its installation.

  • Patent number: 9182183
    Abstract: Fluid is circulated through a heat exchange system for heat exchange to occur at a bundle of tubes making up a portion of the heat exchange system. Heat exchange efficiency at the bundle of tubes requires debris and fouling deposits accumulated therewithin to be substantially removed. Taking the heat exchange system off-line for physical flushing is not only ineffective but also disallow use of the heat exchange system for the duration it remains off-line. Described herein is an embodiment of a cleaning system which uses a displacement system for displacing cleaning balls carried in fluid into the bundle of tubes for cleaning thereof. A flow diverting system is configured and operable for introducing the cleaning balls to the bundle of tubes when in a first operating mode and for retrieving the cleaning balls from the plurality of tubes when in a second operating mode.

  • Publication number: 20150071021
    Abstract: A method of accessing rows and columns stored in a memory system that include memory chips that can be individually addressed and accessed is described. In order to leverage this capability, prior to performing a row-write request on the memory system, a computer system may transform the rows and the columns in a matrix. In particular, in response to receiving a row-write request to write to a row N in the matrix, the computer system rotates the row right by N elements, and writes the row in parallel to address N of the memory chips in the memory system. Similarly, in response to receiving a column-write request to write to column M in the matrix, the computer system rotates the column right by M elements, and writes the column in parallel to the memory chips in the memory system.

  • Patent number: 8917571
    Abstract: The disclosed embodiments provide a chip package that facilitates configurable-width memory channels. In this chip package, a semiconductor die is electrically connected to two or more memory chips. More specifically, contacts on each individual memory chip are each directly connected to a distinct set of contacts on the semiconductor die such that the semiconductor die has separate, unique command and address buses to individually address and communicate with each individual memory chip. Individually addressable memory chips that are each accessed via separate command and address buses facilitate a configurable-width memory channel that efficiently supports different data-access granularities.

  • Patent number: 8918752
    Abstract: A semiconductor die is described. This semiconductor die includes a driver, and a spatial alignment transducer that is electrically coupled to the driver and which is proximate to a surface of the semiconductor die. The driver establishes a spatially varying electric charge distribution in at least one direction in the spatial alignment transducer, thereby facilitating determination of a spatial alignment in more than one direction between the semiconductor die and another semiconductor die. In particular, a spatial alignment sensor proximate to the surface of the other semiconductor die may detect an electrical field (or an associated electrostatic potential) associated with the spatially varying electric charge distribution. This detected electric field may allow the vertical spacing between the surfaces of the semiconductor dies and/or an angular alignment of the semiconductor dies to be determined.

  • Patent number: 8798530
    Abstract: A circuit that receives input signals from a transmitter via proximity communication, such as capacitively coupled proximity communication, is described. Because proximity communication may block DC content, the circuit may restore the DC content of input signals. In particular, a refresh circuit in the circuit may short inputs of the circuit to each other at least once per clock cycle (which sets a null value). Furthermore, a feedback circuit ensures that, if there is a signal transition in the input signals during a current clock cycle, it is passed through to an output node of the circuit. On the other hand, if there is no signal transition in the input signals during the current clock cycle, the feedback circuit may select the appropriate output value on the output node based on the output value during the immediately preceding clock cycle.

  • Patent number: 8482072
    Abstract: A semiconductor die is described. This semiconductor die includes an electro-static discharge (ESD) device with a metal component coupled to an input-output (I/O) pad, and coupled to a ground voltage via a signal line. Moreover, adjacent edges of the metal component and the I/O pad are separated by a spacing that defines an ESD gap. When a field-emission or ionization current flows across the ESD gap, the metal component provides a discharge path to the ground voltage for transient ESD signals. Furthermore, the ESD gap is at least partially enclosed so that there is gas in the ESD gap.

  • Patent number: 8358155
    Abstract: One embodiment of the present invention provides a system that facilitates proximity communication. This system includes a circuit containing a bootstrap transistor and a pass-gate transistor, where the drain of the bootstrap transistor is coupled to the gate of the pass-gate transistor. Note that a first coupling capacitance exists between the source of the pass-gate transistor and the drain of the bootstrap transistor and a second coupling capacitance exists between the drain of the pass-gate transistor and the drain of the bootstrap transistor. During operation, the gate and the source of the bootstrap transistor are coupled to a high voltage, thereby causing an intermediate voltage at the drain of the bootstrap transistor.
