Abstract: PCT No. PCT/BR86/00016 Sec. 371 Date May 8, 1987 Sec. 102(e) Date May 8, 1987 PCT Filed Aug. 21, 1986 PCT Pub. No. WO87/01293 PCT Pub. Date Mar. 12, 1987.The present invention relates to a tracheostomy cannula with a small balloon or cuff (2) positioned posteriorly (or cranially) to the tube (1) which is consequently shorter. This tube (1) has a collar (5) that encircles the tube on its proximal portion and prevents air leakage through the stoma. The "cuff" (2) also may communicate with the environmental air by means of conduits (6) that may be flexible. Since the component structures of a cannula so formed progress only a small distance caudally into the trachea, some complications, if not completely avoided, are better guarded against. Thus, there is when using the present invention less stimulus to a coughing reflex. Moreover, its cleaning and that of the trachea are simpler, and a tracheo-innominate fistula will rarely occur.

Abstract: Disclosed are a process for forming an open-celled microporous membrane (e.g., in film or fiber form) and a novel microporous membrane formed thereby. The process generally includes sequential cold and hot stretching operations, whereby the cold stretching operation is preferably accomplished in a plurality of discrete cold stretching steps. In this regard, the total cold stretch extension is of greater than about 30 percent, and advantageously greater than about 40 percent based upon the initial unstretched length of the nonporous precursor, with this total cold stretch ratio being distributed among a plurality of discrete cold stretching steps. The novel membranes of this invention are characterized by decreased pore sizes and increased pore densities. For example, the membranes of this invention will have an average pore radius as determined by mercury porosimetry of less than about .040 micron. The membranes of this invention, moreover, exhibit a distinctive "bluish" color hue (i.e., a Macbeth Coloreye TM  b* value of less than about -10 as determined by placing a single ply sample of the membrane against a black background).

Abstract: A method for optimizing the pacing and processing of inbound calls and outbound calls. Statistics are generated concerning inbound calls and outbound calls, and concerning the performance of each agent for inbound calls and outbound calls. Separate statistics concerning inbound calls and outbound calls allow a more accurate prediction of call pacing and handling requirements and of the availability of an agent so as to maximize the productivity of each agent and control the on-hold time of inbound and outbound calls. Each trunk line is designated for inbound calls or outbound calls and the status of each trunk is monitored. If all of the trunks allocated to inbound service are in use then some of the trunks designated for outbound service are redesignated for inbound service. If more than a predetermined number of trunks designated for inbound service are not in use then some of these trunks will be redesignated for outbound service. Therefore, the rate of answering of inbound calls and the rate of placement of outbound calls, and the allocation of trunks between inbound calls and outbound calls are driven by the frequency, duration and number of calls and user-selectable options. <IMAGE>

Abstract: In an animation encoding method, an animation decoding method, an animation recording medium and an animation encoder, the present invention suppresses the reduction of information having a fine image pattern while reducing a mosquito noise even in a signal band in which an S/N ratio is low. An animation signal is encoded by using a predetermined anticipation image signal, applying a predetermined operation to the signal so encoded, quantizing the signal obtained by the operation and the signal so quantized is subjected to variable length encoding. In this instance, the signal band in which the S/N ratio of the image signal drops is quantized and highlighted on the basis of non-linear characteristics. On the decoding side, on the other hand, decoded signals are reversely quantized on the basis of non-linear characteristics having opposite characteristics to the encoding side, and decoding is effected. <IMAGE>

Abstract: A method for adjusting the gain of a receive circuit, thereby improving a receiver's immunity to interference. The circuit has an LNA which amplifies the received signal (1702). The receive signal power is controlled by enabling or disabling the LNA in response to the measured received signal power (1704). The received power level is periodically compared to a threshold (1704). When the received power level is greater than the threshold, the LNA is disabled (1706). The LNA is re-enabled when the received power level is less than the threshold (1708), and there are no significant intermodulation components detected (1710). The intermodulation components are detected by briefly enabling the LNA and detecting the resultant change in the measured signal power (1710). If the detected change is more than a predetermined amount, then there are significant intermodulation components present, and the LNA is not re-enabled (1706). Otherwise, there are not significant intermodulation components present, and the LNA is re-enabled (1702).
