Abstract: A method is provided for isolating and processing certain information-of-interest received by a receiver in a Time Division Multiple Access (TDMA) communications system having a receiver and a transmitter. The information-of-interest is transmitted at predetermined intervals. The receiver receives a transmission of signals containing the information-of-interest transmitted from the transmitter. The start of the transmission is sensed from the received signals. The receiver isolates signals received after a predetermined period elapses after the start of the transmission is sensed so as to include the information-of-interest in the isolated signals. Then, the isolated signals including the information-of-interest are processed. In the preferred embodiment, the receiver automatically controls the gain of an amplifier amplifying the received signals in response to the signal power of the received signals. Automatic gain control values of the amplifier are sampled for a predetermined period after the start of the transmission is sensed. A fixed automatic gain control value is determined in response to the sampled automatic gain control values, and the receiver holes the automatic gain control value at the fixed value after the predetermined period elapses until the transmission ofthe information-of-interest ends. Furthermore, the receiver digitizes the received signals, and tags the digitized signals which were digitized from signals received before the start of the transmission is sensed to ignore the tagged signals in processing the information-of-interest.

Abstract: A catheter atherotome (10) and method for its use for performing partial atherectomy in an artery and thereby enlarging the lumen effectively available for blood flow through the artery. Several blades (34) are mounted at a distal end of a catheter (30), in a helical basket configuration and spaced angularly apart from one another about the associated ends of two concentric sheaths (12, 14) in such a way that longitudinal and rotary relative movement of the sheaths selectively bows the blades arcuately outwardly into a cutting position or draws the blades flat into alignment with the sheaths.      The blades (34) have sharpened cutting edges (44) extending helically and directed toward the catheter's proximal end when the blades are bowed. Partial removal of an atheroma is effected by manually pulling the basket knife past an atheroma with the blades (34) in their outwardly bowed cutting positions, with the speed, force, and amount of expansion of the blades determined by the operator. Removal of cut-away pieces of atherosclerotic plaque material may be accomplished either by pull-back of a balloon catheter (60) or by use of a stacking-like filter (262) partially covering the blades (34) to trap the shavings. A tensioning member (284) may be included in a blade.

Title: Folded interdigital notch filter
Inventor: JOHNSON ARLEN KENT
IPC: H01P1/205
Filed: 1992-04-21
Granted: 1996-04-09
Abstract: An interdigital resonant cavity filter structure is folded to provide two adjacent chambers physically positioned side by side and electrically connected in series with each other. A center plate divides the two chambers with a slot at one end of the structure to permit the two chambers to function as one resonant cavity in a folded relation to each other. Each chamber includes interdigital resonators which are related to the overall resonant cavity to produce a band pass filter action within the folded resonant cavity. The input of the filter structure is applied through a port of a circulator connected to one end of the resonant cavity and the output is taken from another port of the circulator. The opposite end of the resonant cavity is terminated in the characteristic impedance of the resonant cavity thereby causing the overall structure to operate as a high quality notch filter.

Abstract: An optical amplification system capable of operating without being affected by the waveform of the incoming optical signal is provided for amplifying the optical signal in its optical waveguide by the effect of stimulated emission of a fluorescent substance induced by pumped light. According to a first aspect of the invention, an optical amplification system turns on its pumping source 8 when there is an optical signal s1 in the optical waveguide 5 whereas the pumping source 8 is kept off as long as no optical signal s1 is found in the optical waveguide 5 so that, when the pumping source 8 is turned on, pumped light from the pumping source 8 is fed to the optical waveguide 5 with a delay of time relative to the incoming optical signal s1. According to a second aspect of the invention, the inside of the optical wave-guide 5 is constantly kept under an excited condition so that, when no optical signal s1 is found in the optical waveguide 5, dummy light s3 is fed to the optical wave-guide 5, whereas no dummy light s3 is fed to the optical waveguide 5 once an optical signal s1 is introduced to the optical waveguide 5. With such an arrangement, since no optical amplification takes place at the rising edge of an incoming optical signal and hence the operation of optical amplification is not dependent on the waveform of the incoming optical signal, a safe and stable optical amplification system can be established.
