20090147556 | LOW POWER MATCH-LINE SENSING CIRCUIT - A low power matchline sensing scheme where power is distributed according to the number of mismatching bits occurring on a matchline is disclosed. In particular, match decisions involving a larger number of mismatched bits consume less power compared to match decisions having a lesser number of mismatched bits. The low power matchline sensing scheme is based upon a precharge-to-miss sensing architecture, and includes a current control circuit coupled to each matchline of the content addressable memory array for monitoring the voltage level of the matchline during a search operation. The current control circuit provides a voltage control signal to the current source of the matchline to adjust the amount of current applied to the matchline in response to the voltage of the matchline. In other words, matchlines that are slow to reach the match threshold voltage due to the presence of one or more mismatching bits will receive less current than matchlines having no mismatching bits. Significant power reduction without compromising search speed is realized since matchlines carrying a match result are provided with the maximum amount of current. | 06-11-2009 |
20150023455 | ADAPTIVE ELEMENT SHUFFLER - A system may include a detector, a controller, a shuffler, and a processor. The detector may detect a signal. The controller may control the shuffler based upon the signal. The shuffler may shuffle a plurality of channels at the input of a plurality of processing elements of the processor based upon the signal. The processor may process the signal according to the plurality of channels as configured by the shuffler. | 01-22-2015 |

20120243640 | RECEIVER - A receiver including: an antenna for receiving signals in a plurality of frequency ranges; a plurality of amplifiers, each of the plurality of amplifiers being configured to amplify signals in one of the plurality of frequency ranges; a plurality of receive paths, each of the plurality of receive paths connecting an output of the antenna to an input of one of the plurality of amplifiers, wherein each of the plurality of receive paths includes a power detector for monitoring signal power in the receive path and a switch which can be operated to activate or deactivate the receive path, wherein the switch of each receive path is operable to deactivate the receive path if an overload condition is detected by the power detector of that receive path. | 09-27-2012 |
20120322399 | NEAR FIELD COMMUNICATIONS RECEIVER - The present application relates to a near field communications (NFC) receiver in which a received NFC signal comprising a carrier signal onto which a data signal is modulated is digitised and downconverted, and the digitised and downconverted received signal is filtered to recover a digitised and downconverted version of the carrier signal of the NFC signal. This digitised and downconverted version of the carrier signal is converted into an analogue signal which is then upconverted to generate an estimate of the carrier signal, and this estimate is combined with the received NFC signal to suppress or negate, at least partially, the carrier of the received signal. | 12-20-2012 |

20160087430 | OVERVOLTAGE PROTECTION FOR NFC DEVICES - The present application relates to a near field communication (NFC) device which has an antenna for receiving NFC signals. The NFC device includes a protection system for protecting a transmit/receive system, and other systems, of the NFC device from potentially damaging voltages that may develop at an output of the antenna if the device enters a strong magnetic field. The protection system includes current control devices that are operative to source or sink current depending upon the polarity of a signal at an output of the antenna, to generate a voltage which at least partially negates a positive or negative voltage at the output of the antenna, thereby reducing the peak voltage at the antenna output. | 03-24-2016 |

20120179430 | MULTI-MODAL MANIPULATION OF A GEOMETRIC MODEL - A method, apparatus, article of manufacture, and computer readable storage medium provide the ability to create a geometric model in a computer-aided design (CAD) application. Direct graphical manipulation via user interaction is used to create the geometric model in the CAD application. The direct graphical manipulation is captured, without additional user input, as one or more lines of script code as if the user is writing the script code. The captured script code is integrated into an environment hosted by the CAD application. The script code is then displayed where it can be modified. The modification of the script code acts to modify the geometric model. | 07-12-2012 |

20140075753 | IMPLANTABLE LEADS WITH A CONDUCTOR COIL HAVING TWO OR MORE SECTIONS - Various coiled conductors having two or more sections and methods and devices for constructing such conductors are disclosed. The various embodiments of coiled conductors and related methods include two or more sections that can have different mechanical, structural, and/or electrical characteristics. | 03-20-2014 |
20140121739 | SUTURE SLEEVES HAVING EXTERIOR SURFACE TEAR RESISTANCE - Various embodiments concern a suture sleeve for securing an implantable lead with a suture. The suture sleeve can comprise a tubular body having a proximal end portion, a distal end portion, an exterior surface, and a lumen, the lumen sized to receive the implantable lead. The suture sleeve can further comprise a suture receiving area along the tubular body, the suture receiving area within a channel that extends around a circumference of the tubular body. An exterior surface of the suture receiving area can comprise a tear resistant feature. The tear resistant feature can be configured to resist initiation of a tear in the exterior surface from the suture. The lumen can comprise an inner surface configured to frictionally engage the implantable lead. | 05-01-2014 |
