Title: Guidewire for crossing occlusions in blood vessels
Inventor: ABELE JOHN E
IPC: A61M29/00
Filed: 1991-11-07
Granted: 2002-09-17
Abstract: A guidewire (10) for penetrating an occlusion (62) within a duct or vessel, such as a blood vessel, has an elongated main guidewire body (20) of a small, first diameter. The guidewire is terminated at its distal end with an enlarged resilient tip portion (24) having a lubricious outer surface (22), and is shaped and constructed to penetrate the occlusion. The guidewire body is con-structed to be relatively flexible in the distal end corresponding to the enlarged tip and relatively stiffer in portions proximal thereof for manipulation of the wire from its proximal end to cause the distal tip portion to penetrate the occlusion and form a passage therein. Tn an embodiment, an outer sleeve (100, 206) is slid over the main body and butting against the proximal end of the enlarged tip portion contributes to axial stiffness of the combination to enable manipulation through the occlusion. After placement this sleeve is removed and a dilatation catheter (50) is slid over the main body, and enters the occlusion behind the-en-larged do portion.

Abstract: Method for allocating the switching-oriented resources of a communication system for switched connections and permanent circuit connections. Call duration information (vdi) is formed in the communication terminal equipment connected to a communication system for switched connections (W) whose call durations can be determined. This call duration information (vdi) is communicated to the communication system within the framework of the call setup.      In the communication system, the ending times of the switched calls are calculated after the through-connection of the switched connections (W) and those switched connections (W) are selected whose indicated call durations end lying closest to the switching deadline before the following switching deadline of a deadline permanent circuit connection (FW). Dependent on the scopes of the switching-oriented resources (WR) allocated to the selected switched (or: dialed] connections (W) and on the scopes of the switching-oriented resources (VR) required for the deadline permanent circuit connections (FV), switched connections (W) are selected from these. Their switching-oriented resources (VR) that become free are then reserved for the respectively provided, deadline permanent circuit connection (FV).

Abstract: A method and apparatus for adaptively adjusting (e.g. thresholding) grayscale image data associates with each document image file (210, 212) a predetermined grayscale adjusting function (216) which can be used to threshold, contrast stretch and gray le-vel reduce the original gray level image of the document into a picture representation for display at workstations, the picture re-presentation yielding increased contrast of written and printed text viewed. The invention includes a method of generating a re-mapping function for use in converting near-photographic docu-ment image pixel gray level data lying in a first range of gray level values to higher contrast, background-suppressed pixel gray level data lying in a second more limited gray level range. Global docu-ment information, such as a histogram of all the document's origi-nal pixels, is used to generate at least one threshold gray level va-lue and to determine the shape of the remapping function on either side of the threshold. Preferably, the remapping function is implemented by a look-up table (216) addressed in accordance with the original pixel data.

Patent CA-2119585-C (CA)
Inventor: NIVENS JERRY W
IPC: F25B40/00
Filed: 1992-09-18
Granted: 2003-05-27
Abstract: The invention comprises a non-restrictive, constant pressure refrigerant recycling and cooling unit that interrupts the nor-mal refrigerant cycle to permit a lower temperature liquid to enter the expansion device (5), and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side of the compressor (9), which acts to reduce the energy requirement and cost to operate the compressor (9). This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements.

Title: Computational complexity reduction during frame erasure or packet loss
Inventor: CHEN JUIN-HWEY
IPC: H04B14/04
Filed: 1995-02-13
Granted: 2001-05-29
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech.  During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only.  This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Title: Method for processing forwarded telephone calls
Inventor: KOCAN STEPHEN M
IPC: H04Q3/00
Filed: 1995-09-13
Granted: 1998-09-22
Abstract: Increased network security is provided in accordance with the invention by usinginformation obtained from the signaling network to determine whether a call has been forwarded, and then using this information to make a determination as to appropriate further call processing, to minimize a communications company's exposure to callforwarding fraud. A determination of whether a call is a forwarded call can be made on the basis of a call forwarding indicator provided by another portion of the communications network. Where such an indicator is unavailable, a determination of whether a call is a forwarded call can be made by comparing the telephone number dialed to originate the call with the telephone number (the "connect number") associated with the telephone station to which the call has been forwarded. When the dialed number and the connect number differ, the call is determined to be a forwarded call.
