  • Publication number: 20120317525
    Abstract: One method implementation disclosed includes detecting matching leaf cells that are functionally identical (optionally, functionally similar) and assigning matching names for the matching leaf cells to replace original, non-matching names. Optionally, digests can be calculated for the leaf cells and used to detect similarities and/or differences. The matching names are propagated to at least some higher-level cells in the hierarchical design, in place of the original names. The method can further include calculating digests for at least some of the higher level cells after the propagating of the matching names into the higher level cells. Various design matching technologies can be used in combination with cell renaming and new name propagation, not limited to use of digests. Dependency chains can be calculated to improve propagation of names through the hierarchy.

  • Patent number: 8301130
    Abstract: An electronic device, referred to as a beacon gateway, capable of communicating an incoming call on one phone to a second phone operating on a different telecommunications network is described herein. A landline phone, voice-over-Internet-protocol phone (VOIP phone), cable phone, and mobile phone may be connected to the beacon gateway. When one of the phones receives an incoming call, the beacon gateway rings the other phones with ring tones indicative of the receiving phone. Additionally, a user can elect to make a phone call across one network (e.g., wireless) from a phone that communicates calls across a different network (e.g., landline). Moreover, a thin client operating in a mobile device is configured to handle communicating inbound calls and outgoing calls on mobile device to other phones connected to the beacon gateway.

  • Patent number: 8266571
    Abstract: The technology disclosed relates to granular analysis of design data used to prepare chip designs for manufacturing and to identification of similarities and differences among parts of design data files. In particular, it relates to parsing data and organizing into canonical forms, digesting the canonical forms, and comparing digests of design data from different sources, such as designs and libraries of design templates. Organizing the design data into canonical forms generally reduces the sensitivity of data analysis to variations in data that have no functional impact on the design. The details of the granular analysis vary among design languages used to represent aspects of a design. For various design languages, granular analysis includes partitioning design files by header/cell portions, by separate handling of comments, by functionally significant/non-significant data, by whitespace/non-whitespace, and by layer within a unit of design data.

  • Patent number: 8175063
    Abstract: Systems and methods for Walsh code assignment are provided. In accordance with the disclosed exemplary embodiments, when a set of mobile communication units (MU) is in a control/hold state, instead of a base transceiver station (BTS) assigning Walsh codes for respective dedicated control channels (dcch ) to the set of mobile communication units (MU) on a one-to-one basis, the base transceiver station (BTS) circulates the Walsh codes among the set of mobile communication units (MU). Thus, at a given time, the base transceiver station (BTS) has assigned the available Walsh codes to only a subset of the mobile communication units (MU) in the control/hold state. Accordingly, this Walsh code assignment allows the system to support more mobile communication units (MU) in the control/hold state.

  • Patent number: 7345946
    Abstract: A wordline driver circuit can include single stage level shifters to translate a low voltage level (VGND to Vcc) to a high voltage level (Vnwl to Vpp). A wordline driver can further include a two-stage discharge circuit to pull down a wordline from a boosted high voltage Vpp to a boosted low voltage Vnwl. A two-stage discharge circuit can include (i) a first discharge path that can pull the wordline toward a first low voltage VGND; and (ii) a second discharge path that can pull the wordline toward a lower boosted low voltage Vnwl. Initially discharging a wordline to a first low voltage can reduce the amount of charge injected into a boosted low voltage Vnwl supply. A two-stage discharge circuit can be self timed or externally timed.

  • Patent number: 7313041
    Abstract: A semiconductor device memory device (300) can include a sense amplifier (302) enabled according to a first sense signal (setn) and a second sense signal (setp). In a sense operation, a first sense signal (setn) can be driven to a first, below ground potential. Subsequently, in the same sense operation, the first sense signal (setn) can be raised and maintained at a ground potential. Such an approach can substantially eliminate a sense amplifier stall condition that can occur under low temperature and/or low voltage operation. According to another aspect of the embodiments, a more negative logical “0” value can be written back into the memory cell during an access and/or refresh operation. This more negative value is available due to the below ground level provided during a sense operation.

  • Publication number: 20070239098
    Abstract: A dressing for treating damaged tissue, incorporates a pair of electrodes and a conductive gel between the electrodes. An electric current passes between the electrodes through the gel to repair the damaged tissue. Sensors can be incorporated into the dressing along with a control unit. The control unit can vary current supplied to the electrodes according to environmental parameters detected by the sensors. Alternatively, one or more pre-defined programmes can be stored in the control unit for supplying an alternating current to the electrodes with a varying amplitude, frequency and waveform.
