Title: Clock frequency coordination for electromagnetic compatibility
Inventor: HOOD RUSH W
IPC: G01D3/00
Filed: 1996-12-19
Abstract: A method for selecting fundamental clock frequencies in order to achieve electromagnetic compatibility in electronic products which employ a plurality of clocks.  The method requires first selecting an ideal frequency for each clock in the product. Then, and until the goal of avoiding coinciding harmonics is complete, the method includes the steps of computing all harmonics of all clock frequencies chosen, determining a minimum difference tolerable in the chosen frequencies and their harmonics for sufficient minimization of electromagnetic interference, and determining if the harmonics of the chosen frequencies coincide impermissibly within the frequency range. If there exists coincidence of harmonics within the predetermined minimum range, then the fundamental frequency of at least one of the clocks corresponding to an interfering harmonic must be adjusted to eliminate the interference.  With the altered fundamental frequency, the steps of computing harmonics, determining if coincidence occurs, and adjusting the fundamental frequency is repeated.

Title: Kiln control based on changing shrinkage rate
Inventor: FULLER JAMES J
IPC: F26B25/22
Filed: 1997-02-27
Abstract: A real-time process and apparatus for controlling conditions in a lumber drying kiln include measuring the shrinkage of a sample of the lumber across the longitudinal axis of the lumber and over time. A slope of the curve is analyzed and can be used to determine when a stress peak and stress reversal occurs in the lumber sample. The detection of the stress peak indicates that the drying schedule of the kiln should be incremented to the next drying step. According to the invention, the schedule is incremented in the fastest possible way without degrading the quality of the lumber.

Title: Method and system for overhead bandwidth recovery in a packetized network
Inventor: MCKAY BRENT MATTHEW
IPC: H04L12/56
Filed: 1997-05-05
Abstract: In a packet network, message packets (130) are comprised of vacant or unused bits for future system enhancements or for remedying unknown design oversights or utilizing vacant portions of fixed length data packets.      Furthermore, message packets (130) comprise a message type identifier distinguishing message architecture. A transmit and receive packet network node (100) maintains an unused bit catalog (125) listing vacant or unused bits of particular message packet types. When a message packet type having vacant or unused bits is detected propagating through the packet network, background data is retrieved from a transmit background data queue (115) and interleaved into such message packets to form enriched message packets (130') for transportation through the packet network. Receiving packet network nodes (100) detect enriched message packets (130') and extract and buffer the background data. A lower data-rate background data transfer mechanism is maintained without impacting the performance of the existing packet network.

Title: A method and apparatus for speech encoding, speech decoding, and speech post processing
Inventor: ISHII JUN
IPC: G10L19/02
Filed: 1994-05-04
Abstract: A speech analysis means and a window locating means are implemented in a speech coding apparatus. The speech coding apparatus encodes input speech per analysis frame defined having a fixed length and is offset at fixed interval.  The speech analysis means extracts frequency spectrum characteristic parameters of the input speech taken within an analysis window.  The location of the analysis window is specified by the window locating means.  The window locating means selects the location of the analysis window which is used in extracting the frequency spectrum characteristic parameters at the speech analysis means.  In this case, depending upon the characteristic parameter of the input speech within and near the frame concerned, the window locating means selects the location of the analysis window within the range which is not to be exceeding the range of the frame concerned.
Patent CA-2215277-A1 (CA)
Title: Electrically operated actuator
Inventor: ELPERN DAVID G
IPC: E05B17/22
Filed: 1997-09-10
Abstract: An electrically operated actuator (12, 112, 212, 312) automatically operates dead-bolt assemblies and other locks, while preserving manual operation of the locks.  The actuator assembly has rotating means for rotation of the drive bar (18), which in turn extends or retracts the bolt (14) of the lock.  The rotating means may be a lever (28, 128, 238, 328, 438) attached to the drive bar (18) that is pivotable about the axis of rotation of the drive bar (18).  The actuator assembly has driving means that forces the rotating means to rotate.  The driving means is responsive to an electrical signal, which, for example, may be initiated from a remote-controlled transmitter (502, 602).  The driving means may include a motor (20, 120, 220) for rotating a rod (22,122, 222, 322) that in turn operates an assembly that rotates or drives the rotating means. In response to an electrical signal, the driving means actuates the rotating means to affect either a locking or unlocking operation, which operations are always completed by placing the actuator assembly in a state whereby the bolt of the lock may subsequently be extended or retracted manually, or automatically by the driving means.

Patent CA-2218281-A1 (CA)
Title: Method and apparatus for noninvasively determining hematocrit
Inventor: RUBEN PAUL W
IPC: A61B5/022
Filed: 1996-04-03
Abstract: This invention is a method and apparatus for non-invasiveness in determining hematocrit, utilizing the frequency dependent electrical impedance characteristics of whole blood by electrically stimulating a patient body portion containing a vascular compartment with a current source over a range of frequencies. A hematocrit measurement system includes a signal generator and demodulator [SGD] (34) that sends an applied signal to an electrode pod (36) that applies a current to a limb of a patient. The electrode pod (36) receives resulting measured voltage signals and provides them to the SGD. The SGD provides to a personal computer [PC] (42) signals indicative of the current passing through the limb of the patient and the resulting voltage. The voltage and current may be measured for various frequencies over, for example, a range from about 10 kHz to about 10 MHz. The electrical impedance from the blood alone is isolated from the total limb impedance from the blood, tissue, bone, etc. by determining the difference between measurement at different blood volumes. The hematocrit is determined by the PC based on inphase and quadrature data provided by the SGD. A neural network (52) may be useful in determining the hematocrit from the blood impedance patterns.

Title: A process for austempering ductile iron
Inventor: LIU XIAOJUN
IPC: C21D1/20
Filed: 1997-10-22
Abstract: A process for austempering ductile iron includes austenitizing a ductile iron casting of low alloy content followed by quenching the workpiece for a controlled period of time in a quench medium such as water, an aqueous polymer solution or a medium speed quench oil. The workpiece is then austempered in an air tempering furnace, resulting in a ausferrite microstructure essentially free of pearlite and martensite, and with mechanical properties meeting ASTM designation A897-90 "Standard Specification for Austempered Ductile Iron Castings." The process eliminates the need for a molten salt bath for quenching and tempering.

Title: Medical connector
Inventor: LOPEZ GEORGE A
IPC: A61M39/06
Filed: 1996-06-07
Abstract: A medical connector is for use in transferring fluids to and from a patient.  The connector has a primary conduit, which has an upstream branch in fluid communication with a primary source of fluid and a downstream branch in fluid communication with a patient. The connector also has a secondary conduit in fluid communication with said primary conduit. Additionally, the connector has a hollow, resilient valve positioned such that the primary fluid can flow through the valve when the valve is in a decompressed state. The valve has a tab extending into the secondary conduit such that a luer inserted in the secondary conduit compresses the tab, thereby preventing flow of the primary fluid through the connector while permitting both flow of fluid to the patient from the luer and flow of fluid from the patient to the luer.
