Title: Contrast-enhanced diagnostic imaging method for monitoring interventional therapies
Inventor: LAUFFER RANDALL B
IPC: A61K49/06
Filed: 1998-09-24
Granted: 2003-05-22
Abstract: The present invention relates to a contrast-enhanced diagnostic imaging method for monitoring the efficacy of interventional therapies. The contrast agents useful in this method comprise an image-enhancing moiety (IEM) and a state-dependent tissue binding moiety (SDTBM). These contrast agents exhibit state-dependent binding to one or more components of a targeted tissue or tissue component and provide a detectable change in the signal characteristics of the agent once bound to the targeted tissue. As a result, these agents exhibit a binding affinity for, and thus image contrast of, the targeted tissue which changes as the tissue-state changes during therapy.

Granted: 1993-06-15
Abstract: TELECOMMUNICATIONS SWITCHING SYSTEM     Abstract A switching system is described in which routing information, which may be associated with packets originating in cellular calls, is divided into information which does not change as the subscriber crosses a cell boundary, and information which does change as the subscriber crosses a cell boundary. Routing procedures associated with the information which does not change as the subscriber crosses a cell boundary are established and stored in the memory of the switch at the beginning of the call. However, routing procedures associated with the information which does change as the subscriber crosses a cell boundary may be derived from the header information of each packet as it arrives at the appropriate portion of the switch.

Title: Vertical synchronizing signal detector
Inventor: FLING RUSSELL THOMAS
IPC: H04N5/10
Filed: 1990-03-29
Granted: 1999-06-01
Abstract: A detector for vertical synchronizing pulses comprises a nonwrapping up/down counter and a comparator. The counter samples the level of a composite synchronizing signal at a sampling rate.  The counter has a numerical output which increases responsive to detection of said level during a sample interval and decreases responsive to nondetection of said level during a sample interval.  The comparator generates a vertical sync detection pulse when the numerical output of the counter is greater than a reference value.  In order to provide hysteresis, the numerical value is alternately one of first and second numerical reference counts, the first reference count being greater than the second reference count.  The comparator initiates the vertical sync detection pulse when the numerical output of the counter rises above the first reference count and terminates the vertical sync detection pulse when the numerical output of the counter falls below the second reference count.  The numerical reference supplied to the comparator is changed at times corresponding to initiation and termination of each vertical sync detection pulse.  A pulse shaping circuit may comprise a latch for sampling the output of the comparator and generating a vertical synchronizing signal.

Patent CA-2026543-C (CA)
Inventor: WELLS STUART C
IPC: G06T5/00
Filed: 1990-09-28
Granted: 2002-02-26
Abstract: The method and apparatus of the present invention takes into consideration that the eye is more sensitive to intensity variations at low levels of intensity than at high levels of intensity and produces higher quality dithered images by employing a sectioned or piecewise linear quantization strategy which sacrifices the fineness of interval spacing at the high end of the intensity scale in order to achieve greater accuracy of reproduction at the low end. The input intensity values are divided into a plurality of sub-ranges indicative of low intensities and high intensities. The number of input intensity levels allocated to the low intensity sub-ranges is small and the number of quantized or output intensity levels allocated to the low intensity sub-ranges is large compared to those allocated to the high intensity sub-ranges such that the interval spacing at the low intensity sub-ranges is small to provide greater accuracy at the low intensity levels where the eye is most sensitive.

Abstract: ABSTRACT OF THE DISCLOSURE An incremental position encoder and method are disclosed herein for a close loop position control system, for example, for positioning a printing device in an electronic postage meter. The incremental position encoder and method includes three chan-nels, first and second of which provide signals for coarse posi-tion determination and first or second and third of which provide signals for fine position determination.  The signals of the first and second channels are 90° out of phase, i.e., they are in quadrature, and the signals of the third channel are in 90° out of phase with the second signal and 180° out of phase with the first signal.  The second and third signals are used to determine fine position.  The encoder includes an encoder wheel having first series and second series of slotted openings for two of the channels, and a third series of narrower width slotted openings for the third channel.  The width of slots of the third series is exactly 1/2 the width of slots of the first and second series, and the slots of the third series  are positioned to lie exactly in the center of the width of slots of either the first or the second series.  The slotted openings of the first and second series are radially spaced from each other and offset by 90°. The slotted openings of the third series are radially spaced in-wardly from the slotted openings of the second series of openings and are offset from the first series by 180° and from the second series by 90°.  Optical sensors sense the presence of the open-ings at respective reference points and provide the three signals described above.

Granted: 1995-02-07
Abstract: A communication network in which a central switching node (70) has at least two sets of both input ports (52) and output ports (56) coupled to respective sets of transmitters (Tjj) and receivers (Rjj) by passive optical networks (54) and (58) and de-multiplexers (52) and mutliplexers (59). The transmitters (Tjj) are tunable so that each can be selectively coupled to one of the input ports (52). The receivers (Rjj) are also tunable so the output ports (56) can be selectively coupled to the one or more of the receivers (Rjj). Alternatively, the demultiplexers (55) and the multiplexers (59) can be tunable. This devolves some of the switching function outside the central switching node (50) reducing the component count.
