Title: Method for buffering high bandwidth data from an input device
Inventor: TANNENBAUM ALAN R
IPC: G06F3/038
Filed: 1992-08-20
Abstract: An efficient buffering mechanism for access and retrieval of stored high bandwidth data and sufficient storage is disclosed. In a typical operating system, a channel containing only a limited buffer between the input devices and the running applications is provided by the operating system. This invention provides a parallel channel of a higher bandwidth with a far superior buffering capability that complements that of the operating system.     When an input event from an input device with a high bandwidth is received by the system, messages are sent to both the operating system channel and the high bandwidth channel in a compatible format for each channel. The message sent to the operating system channel generally contains only limited data which may have to be translated from the actual input data to be acceptable to the operating system. The message sent to the high bandwidth channel contains the full spectrum of data generated by the input device, The buffer in the operating system channel also has the property of discarding data if the application does not retrieve them quickly enough during periods of high CPU utilization. The buffer in the high bandwidth channel keeps all data for up to 1000 input events, or whatever is deemed sufficient for the computer system, regardless of CPU usage.      In response to the interception of a translated event in the operating system queue for one of the applications in the system, the method of the present invention will check to see if there are any events in the high bandwidth buffer.     If there are, the system dequeues all the events to send them to the intended application. Various flags are set if task preemption is detected by the system upon examination of the events in the high bandwidth queue. Further, certain events may be sent asynchronously to the high bandwidth channel alone from various input devices; the system is prompted by a false "mouse" message in the operating system queue to cause the system to examine the high bandwidth buffer for the true input event.

Title: Method and apparatus for continuously measuring volumetric flow
Inventor: MCKOWN RUSSELL C
IPC: A61B5/0275
Filed: 1991-04-18
Abstract: Method  and  apparatus  (FIG.  15)  for  adapting  the volumetric flow rate measurement system taught by Yelderman in U.S. patent no. 4,507,974 to clinical environments by reducing the effects of physiological noise.  Signal processing techniques are used to characterize the background noise power spectrum of the system under test so that the effect of noise aberrations on the measured data may be eliminated and so that the predominant periodicities of the background noise spectra may be avoided. The invention further cross-correlates the input data of the system with the corresponding output data of the system to determine weighting values for each input frequency so that data collected at noisy frequencies is discounted.   Low frequency noise or drift is also removed from the output signal by fitting the average of the output data to a quadratic function which is then subtracted from the original output signal, point by point. Finally,  the  processed  data  is  fit  to  a  lagged  normal distribution curve in the frequency domain to solve for the parameters  necessary  to  mathematically  model  the  transfer function of the system.  Given the input to the system as well as the frequency domain transfer function and noise data of the system, the volumetric flow of the system then may be determined for virtually any input even in very noisy environments.

Title: Hermaphroditic connector for single fiber optical cable
Inventor: DARDEN BRUCE V
IPC: G02B6/36
Filed: 1992-11-13
Abstract: A single optical fiber hermaphroditic connector includes a ferrule or plug of a subassembly which terminates an optical fiber of a cable and an end of which is received in a cavity of a housing. Furcations of a bifurcated member extend beyond a free end of the ferrule. An end of the housing is supported from one free end of a tubular member such that a compression spring disposed about the housing causes the ferrule to be biased outwardly. An opposite end of the tubular member is connected to a bushing and tapered plug arrangement which is effective to transfer forces from strength members of the cable to the connector to prevent the forces from being applied to the connection. The subassembly is received in a sleeve having a small diameter threaded end adjacent to the force transfer arrangement and an enlarged diameter, externally threaded end which encloses the housing and the bifurcated member. A coupling nut having an internally threaded end is disposed about the sleeve and is adapted to receive a free end of another single fiber hermaphroditic connector such that the internally threaded free end of the coupling nut is turned into engagement with the externally threaded enlarged end of the sleeve of the other connector to hold together the connectors.

Title: Process for electrode control of a dc arc furnace, and an electrode control device
Inventor: STREBEL EDUARD
IPC: H05B7/148
Filed: 1993-03-05
Abstract: ABSTRACT OF THE DISCLOSURE      Direct current arc furnaces (8) have a current regulator (14) for maintaining the current of an arc (10) constant, and an electrode control (18) for affecting the position of an electrode (7) of the arc furnace (8) and thus the length of an arc (10).          Control of the position of the electrode (7) is effected by means of  a hydraulic  electrode  adjustment device  (21),  which  is controlled  as  a  function  of  the  difference  between  a predeterminable electrode control  input signal  (.alpha.soll)  and an actual rectifier value signal (.alpha.ist) at the output of the current regulator (14).  In this way the length of the arc is controlled in such a way that a rectifier (5) operates with a mean control of for example, 25° el., independent of the secondary voltage of a furnace transformer (2) and of a set current reference value (isoll).  Limit values are monitored and undesirable frequencies are filtered out by means of a band-pass filter (16) between the output of the current regulator (14) and a comparator or adder (17)  for forming the difference signal between the electrode control input signal (.alpha.soll) and an actual rectifier value signal (.alpha.ist).

Title: Rapid assay for detection of nucleic acid-binding factors
Inventor: MEIER TIMOTHY I
IPC: C12Q1/68
Filed: 1993-03-17
Abstract: Abstract This invention consists of methods for the detection of nucleotide-binding compounds in complex fluid mixtures.  The invention consists of fixing a target polynucleotide of known sequence to a non-porous support which comprises or is contained within a container.  The challenging sample fluid is then introduced in such a way that compounds present in the fluid bind to the target polynucleotide.  This binding blocks the hybridization of a second, complementary polynucleotide to which is attached a label comprising a moiety capable of generating a detectable signal.  The invention further provides for indirect means of binding the target polynucleotide to the support and of generating the detectable signal.

Title: Reclosable bag with offset end seal
Inventor: BRAY BARRIE A
IPC: B65D33/18
Filed: 1993-09-30
Abstract: ABSTRACT OF THE DISCLOSURE    The closable bag with offset end seal comprises a layer of plastic  folded  over  itself  to  create  an  elongate  strip  of interconnected pockets which are separable from one another along the strip to create individual bags.   Interposed between free overlying ends of the plastic strip is a gasket made of a heat sealable material having a low surface tension and coefficient of friction.  A side edge of these three layers is heat sealed and scored to provide a tamper indicating strip which must be removed to open the bag.  Slightly lateral to this strip is a section of the bag where the gasket is heat sealed along its length to one of the layers of plastic, with a remaining inwardly extending portion of the gasket being free to move away from the layer to which it sealed, creating an inwardly directed flap. On a surface of the unattached layer of plastic facing the gasket are provided two spaced apart longitudinal strips of adhesive which cause engagement between the layer of plastic and the gasket flap.  Thus, if product within the bag moves toward the seal end of the bag, it rests between the gasket flap and the layer of plastic to which it is heat sealed, without directly resting against the area of closure and compromising effectiveness thereof.
