Abstract: The present invention relates to novel use of koumine, an alkaloid monomer from Gelsemium elegans Benth., or a pharmaceutically acceptable salt thereof, and more particularly to use of koumine or its pharmaceutically acceptable salt in the preparation of a medicament for the treatment of inflammatory bowel disease.

Abstract: An apparatus including a front port, a plurality of back ports and a plurality of switches. The front port may be configured to send/receive data to/from a controller. The plurality of back ports may each be configured to send/receive the data to/from one of a plurality of logical units of a memory. The plurality of switches may each be configured to connect the front port to one of the back ports in response to an input. The input may be received from the controller and may also be presented to the memory.

Abstract: A Method and Apparatus for Fast Frequency Acquisition in PLL System has been disclosed. In one implementation a time to digital converter is used with cycle slip detection for fast acquisition and lock. In one implementation cycle slip detection is applied to determine if a feedback clock from an oscillator is faster than a reference clock or not in one measurement cycle.

Abstract: Methods and systems for peak detection as part of automatic gain control in high-speed communications are provided. A peak detection system uses a portion of an input signal to generate a reference signal for comparison with the input signal. The comparison produces a differential error signal that is in turn used to produce one or more full swing pulses based on the comparison. A pulse counter counts the pulses, and if the count in a single clock cycle is above a determined threshold, a binary error signal is set to indicate a need for correction.

Abstract: Methods and systems for conditioning wireline communications to remove intersymbol interference are provided that used adaptive equalization. The method and systems include using a digital finite state machine to control two feedback loops that adjust the gain and power of the input signal relative to a supplied reference. The eye height of the input signal is conditioned by a gain feedback loop so that signal equalization can be performed in a known state. The digital finite state machine allows the loops to be flexibly run in sequence or concurrently. The adaptation functions can be shut off when adequate signal equalization has been achieve, thus saving power.
