  • Patent number: 11405872
    Abstract: Systems and methods are provided for managing uplink interference in a high noise environment. In response to determining that an observed received signal strength indicator (RSSI) exceeds a reference RSSI, a user device may be determined to be disposed in a high noise environment. In order to mitigate the impact of the high noise environment on the uplink, one or more interference mitigation procedures may be executed that may directly, or result in, the handoff of the user device from a first cell with a greater noise to a second cell with less noise.

  • Patent number: 5592403
    Abstract: A digital signal processor (DSP) circuit is configured to recursively retrieve and process pairs of data points in a symmetric digital filter. The data points are retrieved from an external source (e.g., compact disk) at a first frequency, and processed within the DSP at a second frequency. The DSP employs a floating pointer scheme, which effectively functions a buffer to thereby compensate for jitter or drift between the first and second frequencies.

  • Patent number: 5536955
    Abstract: A device for use in rapidly generating integrated circuit structures is disclosed which provides a plurality of objects and primitives, each primitive having a well of one type of semiconductor conductivity, one FET device of the same conductivity type, one other FET device of an opposite conductivity type, a doped polysilicon conductor connecting together the gates of the FET devices, a positive voltage supply, and a negative or ground voltage supply. This device is particularly defined for rapid transformation into integrated circuit structures that produce integrated circuits having optimized cell structures, minimum overall circuit area, high performance, and reliability.

  • Patent number: 4244865
    Abstract: This invention relates to the synthesis and use of novel .alpha. hydroxy tripeptide substrates which are useful in the quantitative determination of proteolytic enzymes such as thrombin and trypsin. In use, the disclosed substrates are hydrolyzed by a proteolytic enzyme to yield a moiety that can be evaluated spectrophotometrically to indicate the quantity of enzyme present.
