Title: Efficient synthesis of musical tones having nonlinear excitations
Inventor: SMITH JULIUS O III
IPC: G10H1/12
Filed: 1996-05-10
Abstract: An efficient digital waveguide synthesizer is disclosed for simulating the tones produced by a non-linearly excited vibrational element coupled to a resonator, such as in a piano. In a preferred embodiment, the synthesizer creates an excitation pulse from a table containing the impulse response of a piano sound board and enclosure. Alternately, this excitation pulse can be synthesized by filtering white noise. The excitation pulse is fed into the filter that simulates the collision of the piano hammer and string. Because the hammer-string interaction is nonlinear, the characteristics of this filter vary with the amplitude of the tone produced. The filtered excitation pulse is then fed into a filtered delay line loop which models the vibration of a piano string. Because the excitation pulse already contains effects of the resonator, the tone produced by the delay line loop does not require additional filtering in order to model the resonator.

Title: Process for joining alumina ceramic bodies
Inventor: HEGNER FRANK DR
IPC: C04B37/00
Filed: 1997-09-29
Abstract: This process serves to form a long-time-vacuum-tight, high-strength, and corrosion-resistant joint, by means of a joining material, between a first body and a second body each made of sintered, polycrystalline alumina ceramic with a purity greater than 92 wt.% or of sapphire. The joining material is interposed in the form of a paste, a foil, or a slip between the first body and the second body. The joining material has been made from 1) an agglomerate-free, highly disperse, high-purity .alpha.-alumina powder with particles of as high a degree of calcination as possible and of a size not exceeding 100 nm (= 10-7 m), 2) an anorganic oxidic powder of an auxiliary sintering agent with particles of approximately the same size as the particle size of the .alpha.-alumina powder, 3) an organic vehicle which is dissolved or suspended in an organic or aqueous solvant and in which the particles of the respective powder are distributed as evenly as possible. Instead of the anorganic oxidic powder of an auxiliary sintering agent an anorganic oxidic auxiliary sintering agent produced chemically as envelopes around or attachment to the particles of the .alpha.-alumina powder can be used, the total .alpha.-alumina and auxiliary-sintering-agent content of the paste, the foil, or the slip ranging between 50% and 70%. After interposing the joining material the bodies are heated to a temperature of not more than 1,300 °C and then allowing them to cool down. After cooling the alumina content is at least 95 wt.% and the auxiliary-sintering-agent content at least 5 wt.%.

Title: Automatic border delineation and dimensioning of regions using contrast enhanced imaging
Inventor: LEVENE HAROLD
IPC: G06V10/28
Filed: 1996-05-30
Abstract: The present invention is a novel system and method for automatically identifying borders of regions of interest within an image of a patient's organ or tissue. The system generates images - before, during and after the administration of a contrast agent. Once the set of images have been taken, the system begins automatic processing of the images. The steps of the processing include the identification of baseline image frames, identification of baseline intensities for each given pixel in the ROI, baseline subtraction on a per-pixel basis, determining a probability of signal-to-noise ratio for each pixel, and thresholding each pixel to determine if a pixel belongs to an area inside the border region or an area outside the border region. To exactly determine which pixels that are at the border, the method refines the set by locally minimizing a total cost function that relates a low value to points typically found on a contrast enhanced image. The border of the region of interest is thereby determined.

Title: Range repeater for a transmission system
Inventor: BI QI
IPC: H04B7/15
Filed: 1997-11-28
Abstract: The invention is a repeater for a telecommunications transmission system such as a CDMA wireless system. The repeater reduces leakage by means of a feedback signal whose amplitude and phase are adjusted in response to the amplitude and phase of a sampled input signal when a switch turns off the normal output of the repeater for a short period of time. In one embodiment, a pilot signal is transmitted during this time period so that the sampled input is the leakage signal. In another embodiment, the sampled input is the normal transmission signal received during the time period.

Filed: 1998-01-12
Abstract: A system and method for providing peer-level access control on networks that carry packets of information, each packet having a 5-tuple having a source and destination address, a source and destination port, and a protocol identifier.  The local rule base of a peer is dynamically loaded into a filter when the peer is authenticated, and ejected when the peer is loses authentication.  The local rule base is efficiently searched through the use of hash tables wherein a hashed peer network address serves as a pointer the peer's local rules.  Each rule comprises a 5-tuple and an action.  The action of a rule is carried out on a packet when the 5-tuple of the rule corresponds to the 5-tuple of the packet.

Patent CA-2234894-A1 (CA)
Inventor: FISCHELL DAVID R
IPC: A61F2/958
Filed: 1998-04-14
Abstract: The present invention is a balloon angioplasty catheter that combines a catheter shaft having increased pushability with an elongated, gradually tapered, highly flexible, lubricity coated, distal tip that is specifically designed to penetrate through a tight stenosis. The distal end of the tip is formed as a very thin-walled, tapered, frustrum of a cone that is capable of following a guide wire through even the most tortuous coronary arteries. The proximal end of the tip has a diameter that is equal to or slightly larger than the diameter of an angioplasty balloon that is wrapped around a catheter shaft at a distal section of the balloon angioplasty catheter. One embodiment of the invention includes a thin-walled tube lob at the proximal end of the distal tip which extends over the distal end of the angioplasty balloon. This design can prevent the distal end of the wrapped pre-deployed balloon from engaging the arterial wall as it is pushed through a tight stenosis. The balloon angioplasty catheter can be designed with the capability for either or both a rapid exchange or over-the-wire mode.
