Title: Non-contact characterization and inspection of materials using wideband air coupled ultrasound
Inventor: SCHINDEL DAVID W
IPC: G01N29/14
Filed: 1996-02-12
Granted: 2003-10-14
Abstract: A system for the non-contact inspection and characterization of an object in which wideband (40kHz to approximately 2MHz) air/gas coupled ultrasonic transducers are used.  The system of the present invention enables a single set of transducers to be used in an inspection/defect detection arrangement to characterize materials having a wide range of through-thickness, and other resonances.  For example, the through-thickness fundamental resonance of 11mm thick plywood is 44kHz, 723kHz for 2mm thick carbon fibre, and 1.47kHz for 0.75mm thick polystyrene, all of which are measurable in the same system.  The system is used in a method to characterize a defect by being able to operate at or near the resonant frequency of the normal material and at or near the resonant frequency of the material in a defect region to improve the accuracy of detecting specific types of defects including inclusions, material thinning, delamination and pitting by monitoring changes of various attributes (e.g. amplitude, frequency) of the detected output signal.  The system of the present invention can also be combined with laser or EMAT systems, where the means for generating ultrasonic vibrations in the object is a laser or EMAT and in pulse-echo arrangements in which a single wideband air-coupled transducer is used as the source and as the receiver/detector of ultrasound.

Title: Liquid chemical applicator measuring device
Inventor: KNUTSON SCOTT WILLIAM
IPC: B05B12/00
Filed: 1996-10-23
Granted: 2005-07-26
Abstract: A means of accurately measuring farm chemical during its application, through the use of load cell and a means of mounting this load cell to a sprayer apparatus is disclosed. The measurement of the chemical is accomplished by the use of a load cell which is mounted in a position below a keg of liquid farm chemical. The load cell measures the weight of the chemical keg and the liquid chemical contained therein. By knowing the specific gravity of the chemical being used and the weight of the keg itself, the operator can accurately compute the volume of chemical which has passed through the sprayer system and the rate of that passage. This gives the operator an accurate measure of the amount of the liquid chemical applied to each acre of crop land.

Title: Hyper-text document preparing apparatus
Inventor: INOUE KAZUNORI
IPC: G06F17/30
Filed: 1996-11-29
Granted: 2000-03-28
Abstract: A plurality of elements of a document is classified into a plurality of services respectively relating to a meaning, and a plurality of nodes respectively indicating one element are prepared in a node preparing unit. Therefore, each of services is a partial set of nodes. Also, a plurality of inner-service links respectively connecting a pair of nodes of the same service are prepared by an inner-service link preparing unit, so that a reference relationship between the nodes is indicated by one inner-service link. Also, a plurality of inter-service links respectively connecting a pair of nodes of different services are prepared by an inter-service link preparing unit, so that a reference relationship between the nodes of different services is indicated by one inter-service link. A hyper-text document is prepared by connecting the nodes prepared by the node preparing unit through the inner-service links for each service and connecting the nodes of the services through the inter-service links. Accordingly, because the nodes are classified into the services, the hyper-text document can be easily prepared, and the hyper-text document can be easily renewed. Therefore, a user can easily manage the hyper-text document.

Title: Access platform for internal mammary dissection
Inventor: TAYLOR CHARLES S
IPC: A61B19/00
Filed: 1997-02-14
Granted: 2000-12-05
Abstract: An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade.  The superior blade is pivotally coupled to the spreader member such that it naturally rises as the blades are separated.          Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery.  A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.

Title: Asymmetric coupling method
Inventor: GOUGH CAMERON
IPC: H04B10/24
Filed: 1997-05-13
Granted: 2000-11-14
Abstract: Downstream and upstream signals in a transmission system are attenuated by different amounts to allow upstream signals to be originated at individual subscribers (22-22, 30-30) at the same level yet be received at a common upstream amplifier (19b) at substantially the same level. Different attenuation of downstream and upstream signals is achieved by the combination of a pair of directional couplers (110a and 110b) and a diplex filter (132). The couplers and diplex filter collectively separate a downstream signal destined for the subscriber from an upstream signal generated by the subscriber. The upstream signal which is separated may be attenuated by a matching loss element (138) to attenuate the upstream signal by an amount greater or less than the downstream signal.

Granted: 2000-10-17
Abstract: The apparatus provides a locking mechanism for an armrest of an automobile or similar motor vehicle to a structural pin or post. The mechanism includes a cap with a lateral slit into which a button and spring are assembled. The spring outwardly biases the button which is limited in its outward travel by a detent arrangement which maintains the outer portion of the button flush with the cap. In this arrangement, the spring further engages a circumferential slot on the structural pin or post thereby locking the armrest to the structural pin or post. However, in order to remove the armrest from the structural pin or post, the user pushes thebutton inwardly, thereby compressing the spring and moving the spring out of thecircumferential notch thereby unlocking the armrest from the structural pin or post and allowing the free removal thereof.

Title: Traffic rate controller in a packet switching network
Inventor: MURASE TUTOMU
IPC: H04L12/811
Filed: 1998-09-18

Abstract: A packet switching network includes a transmitting station, an ATM switching system and a receiving station. The transmitting station has a trafficrate controller for controlling the traffic rate based on the congestion in the ATM switching system as well as the data cells stored in the transmission data storage section for receiving data for transmission.  The traffic rate controller controls the number of transmitted cells between adjacent forward resource management (FRM) cells, thereby avoiding a reduction in the traffic rate during data transmission which is caused by lack of available data for transmission supplied to the transmission station.
