Title: Method for eliminating ringing during a nuclear magnetic resonance measurement
Inventor: BOQIN SUN
IPC: G01R33/44
Filed: 1999-05-27
Granted: 2002-02-05
Abstract: The present invention relates generally to a method for eliminating ringing while measuring nuclear magnetic resonance properties of an earth formation traversed by a borehole. The measurement can be made while drilling or using a wireline tool.  During a first time period of a single pulse sequence, the measurement includes the desired spin-echoes and the undesired effects, that is, ringing, measurement noise, and baseline shift. During a second time period of the single pulse sequence, the spin-echoes are eliminated but not the undesired effects. Using the signal collected during the second time period, the signals measured during the first time period are corrected to eliminate the ringing component, measurement noise, and baseline shift.

Title: Parathyroid hypertensive factor
Inventor: LEWANCZUK RICHARD Z
IPC: A61K31/55
Filed: 1990-03-22
Granted: 2001-08-21
Abstract: A new circulating factor from the parathyroid gland of some hypertensive mammals has been isolated and characterized. Polyclonal and monoclonal antibodies raised against this factor are usable as a screen for the presence of the factor. The factor is involved in the control of calcium uptake in cells. Hypertensive mammals may be treated to lower mean blood pressure by administering a calcium channel blocking agent together with one or both of a calcium supplement and Vitamin D. The hypotensive effect of this combination is synergistic and the dose response is more predictable than the administration of any of these agents singly.

Granted: 2007-06-05
Abstract: A channel encoder/decoder apparatus varies an iterative decoding number according to service type, data class and channel condition. A message information receiver receives information about a message to be received. A controller determines an iterative decoding number of a decoder according to the message information received. A decoder iteratively decodes the received message according to the determined iterative decoding number. The message information includes a class of received data, and the class includes a required bit error rate (BER). The iterative decoding number is increased for a lower BER. Further, the cla ss includes a permissible time delay, and the iterative decoding number is increased for a longer permissible time delay. In addition, the message information includes a service type of received data, and the iterative decoding number is decreased when the service type is a moving picture service.

Abstract: A system that provides additional voice lines with data over a single two-wire subscriber loop. At the subscriber premise, one or more telephone instruments and data devices are connected to a digital modem into either a voice or a data interface. Analog voice signals are PCM sampled then packetized, and voice and data packets are transmitted to a CO modem over the subscriber loop. The CO modem depacketizes the voice packets into PCM format and transmits PCM voice information to a CO switch over a standard digital trunk interface. Data packets are routed to a data network.  Voice packets are given transmission priority over data packets to ensures that voice is transported in the presence of data with low latency.
