Patent number: 6449254Abstract: A data communication network operating in asynchronous transfer mode has a data transmission node and a data reception node. The nodes transfer data cells having associated headers followed by associated payloads. Each header indicates whether or not the associated cell is unassigned, is idle, or has an erroneous header. A filter of the data reception node stores each header of the sequentially received cells in a header memory. The filter stores, in a cell memory, cells that are non-idle, are assigned, and have non-erroneous headers. The filter rejects from storage payloads associated with idle, unassigned, and erroneous cells.Type: GrantFiled: December 11, 1998Date of Patent: September 10, 2002Assignee: Analog Devices, Inc.Inventor: Massoud Hadjiahmad

Patent number: 6441764Abstract: An apparatus and method for subband signal coding, using algorithms of comparable complexity to conventional coders, that exploits a noisy analog signal at the decoder. It is assumed that the analog signal is the output of a channel through which the source is sent uncoded. By using the analog signal at the receiver, the required digital bit rate is able to be reduced while offering comparable fidelity to conventional coding systems that ignore the analog signal. Concepts from conventional subband coding, e.g., subband decomposition, quantization, bit allocation, and lossless bitstream coding, are tailored to exploit the analog signal at the receiver such that frequency-weighted mean-squared error (MSE) is minimized. Because subband coefficients are coded, all results pertaining to perceptual masking are easily applied to this method of coding.Type: GrantFiled: May 5, 2000Date of Patent: August 27, 2002Assignee: Massachusetts Institute of TechnologyInventors: Richard Barron, Alan V. Oppenheim

Patent number: 6435182Abstract: A novel ventilator waveform having an enhanced inspiratory flow pattern is ideally suited for determining an effective “inspiratory impedance” in ventilator-dependent patients, and/or patients with severe obstruction resulting in expiratory flow-limitation. This waveform is referred to herein as the “Enhanced Ventilator Waveform” (EVW). The EVW maintains ventilatory support while simultaneously providing an accurate and sensible assessment of the mechanical status of the lungs or total respiratory system. The EVW technique of the present invention ensures that normal (tidal) volume levels are delivered during each inspiration, and that expiration remains passive. Furthermore, accurate estimation of lung resistance and elastance is established for several frequencies surrounding the primary ventilator breathing rate. From the resistance and elastance data, the mean level and structural distribution of airway versus tissue constriction conditions in the lung can be inferred.Type: GrantFiled: March 24, 2000Date of Patent: August 20, 2002Assignee: Trustees of Boston UniversityInventors: Kenneth R. Lutchen, David W. Kaczka, Bela Suki

Patent number: 6437581Abstract: Two-wire sensors for measuring physical quantities have only two connections (A1, A2), which serve to connect the power supply and also to conduct the measuring signals. However, because two-wire sensors have the property of controlled current sources, they can be connected only in parallel. Consequently, for a parallel circuit of n two-wire sensors disposed at different locations, two n lines are required. To reduce the number of lines, a two-wire sensor is provided with an end stage (W), which generates an output voltage (UA), which is a measure of the physical quantity measured by a measuring sensor (S) and which is always greater than an adjustable reference voltage signal (Uref). Because the inventive two-wire sensor therefore has the property of a voltage source, several of them can be connected in series. Consequently, even for a series circuit of several two-wire sensors, only two lines are required.Type: GrantFiled: April 25, 2000Date of Patent: August 20, 2002Assignee: Micronas GmbHInventor: Lothar Blossfeld
