Title: Acoustic isolator for downhole applications
Inventor: EGEREV SERGEY
IPC: G01V1/52
Filed: 2000-06-01
Abstract: A plurality of heavy mass irregularities (54, 56, 58) attached to an inner wall (60) of the drill collar (52) attenuate waves traveling through the collar. The plurality of heavy mass irregularities (54, 56, 58) are spaced and sized for the maximum attenuation of acoustic pulses in a predetermined frequency range. The mass irregularities may be rings secured to the inner surface (60) of the collar by neck pieces (62), extending outwardly from the outer circumference of the ring. The mass irregularities may be made of steel or tungsten and are between six and ten in number. The spacing of the irregularities may lie between twelve and fourteen centimeters. A center pipe (64) may be included to isolate the irregularities from the fluid flow associated with the drilling operation. The pipe may be of a soft material such as rubber to reduce transfer of acoustic noise along the drill string.

Title: Translating and executing object-oriented computer programs
Inventor: HINSLEY CHRISTOPHER ANDREW
IPC: G06F9/45
Filed: 2000-08-16
Abstract: A method of translating object-oriented computer programs into native code includes a two-step translation process, first by a code translator (212) into a machine-independent virtual processor code (213), and then by a native translator (214) into native code (230). In a heterogeneous multiprocessor environment, the machine-independent part of the translation can be carried out at the central server, with machine-independent virtual processor code being distributed as required to the individual clients. Each client then needs to carry just a small processor-dependent native translator (214) with which it completes the conversion into native code. The invention finds particular application in embedded systems, and particularly in heterogeneous-processor systems such as mobile phone networks.

Inventor: XIANG ZENG-JUN
IPC: H04W92/02
Filed: 2000-08-29
Abstract: A system and method for IP-based call routing in an integrated telecommunications network having a packet-switched network portion (e.g., a Voice-over-Internet Protocol (VoIP) network portion (14) and one or more circuit-switched network (CSN) portions (12) such as a PSTN (50) or a radio telephony network. A mobile Switching Center (MSC (24)) serving one or more mobile subscribers (28) is provided with an Internet Protocol (IP)-Interworking Unit interface (30) towards the VoIP network portion. The radio telephony network also includes a Location Server (LS(18)) containing mapping information between routing numbers (e.g., Temporary Location Directory Numbers or TLDNs), called party numbers (B-numbers) and IP addresses of entities to which a call can be routed over an IP trunk from the MSC. A  querying mechanism is provided in the MSC for interrogating the LS based upon a routing number, a called party number, or both, provided to the MSC. The MSC  obtains an IP address from the LS which is used for effectuating the IP trunk.  A plurality of Bearer Independent Call Control (BICC) messages and a plurality of Integrated Services Digital Network (ISDN) User Part (ISUP) messages are transmitted among the various nodes of the integrated telecommunications network, e.g., one or more MSCs with the IP interface, a Local Exchange of the PSTN, etc. for establishing the IP trunk. Where an IP trunk is not available, a circuit-switched path (e.g., a Synchronous Transfer Mode (STM) trunk), is utilized in the call path. The IP trunk is implemented using Real-time Transfer Protocol (RTP) and Session Description Protocol (SDP) to convey the voice payload associated with the call.

IPC: A61L2/025
Filed: 2002-08-08
Abstract: A portable dental system and method is disclosed for cleaning endodontic files and the like during a operation such as a root canal procedure. This allows a dentist to clean files in situ while performing the removal of root material. As the file is withdrawn from the patients mouth by the dentist, it can be inserted into a sealed container through the lid and can be cleaned ultrasonically and immediately withdrawn and reinserted into a patients tooth canal for further removal of tooth and root material. Debridement of the files ensures less likelihood the file will break within the canal; furthermore, since no passing off to or cleaning the tip by an assistant is required, there is less likelihood of inadvertent skin puncturing and infection of the dentist or assistant. The sealed disposable container housing a cleaning fluid is insertably removable from the base, which supports it and provides a source of ultrasonic energy thereto.
Patent CA-2397921-A1 (CA)
Inventor: MERY DOMINGO
IPC: G01N23/04
Filed: 2001-01-08
Abstract: The invention relates to a novel method for automatically inspecting e.g., aluminium cast parts using a monocular sequence of X-ray images taken of the  test piece in different positions. Known methods for the automatic detection  of casting defects use modified median filters which estimate X-ray images that are free of defects using recorded X-ray images. These images are compared with each other and casting defects are detected when a particularl y great difference exists between them. However, the configuration of each filter depends to a considerable extent on the size, shape and position of t he constructional structure of the test piece. These characteristics of the tes t piece therefore have to be considered a priori. The invention provides a method enabling casting defects to be automatically detected in two steps. T he method uses a single filter and no a priori knowledge of the structure of th e test piece. Aside from calibration, the first step of the method segments hypothetical casting defects in each image in the sequence. The second step entails trying to trace the hypothetical casting defects in the image sequence. The basic idea behind the inventive method is the assumption that the hypothetical casting defects that cannot be traced in the sequence are detection errors. By usingthis method it is possible to detect true casting defects with maximum probability and eliminate detection errors. The process  of tracing the hypothetical casting defects in the image sequence is carried  out according to the principles of multiple image analysis. Bifocal, trifoca l and quadrifocal tensors are used to reduce the calculation time. A 3D- reconstruction is produced of the hypothetical casting defects traced in the  image sequence, enabling those which do not belong to the test piece space t o then be eliminated. The robustness and reliability of the method are checked  with semi-synthetic and real X-ray image sequences taken of an aluminium rim  with known material defects. The true casting defects are detected and the detection errors are eliminated.
