Title: Nuclear level sensing gauge using scintillating fiber bundle
Inventor: HOUILLION PAUL L
IPC: G01F23/288
Filed: 1999-03-30
Abstract: A nuclear level sensing gauge (10) for measuring the level of product (16) in a bin (14) utilizes a bundle (12) of scintillating fibers. A source (18) of nuclear radiation positioned adjacent the bin, and a bundle of one or more scintillating fibers is positionned adjacent the bin opposite the source of nuclear radiation such that nuclear radiation passing through the bin impinges upon the bundle.

Title: Method and apparatus for calculating a reciprocal
Inventor: KROUGLOV ALEXEI
IPC: G06F7/483
Filed: 2000-12-20
Abstract: A method and apparatus for the calculation of the reciprocal of a normalized mantissa M for a floating-point input number D . A formula for determining the minimum size for the look-up table in accordance with the required precision is provided, as well as formulas for calculating look-up table entries. The look-up table stores the initiation approximations and the correction coefficients, which are addressed by the corresponding number of the mantissa's most significant bits and used to obtain the initial approximation of the reciprocal by means of linear interpolation requiring one subtraction operation and one multiplication operation. The result of the linear interpolation may be fed to a Newton-Raphson iteration device requiring, for each iteration, two multiplication operations and one two's complement operation, thereby doubling the precision of the reciprocal.

Patent CA-2341012-A1 (CA)
Inventor: NAKAGOMI SHOJI
IPC: B02C18/18
Filed: 2001-03-15
Abstract: To avoid reduction in efficiency of rough fragmentation operation with a rough fragmenting blade by making it difficult for fragments to stay in clearances between rough fragmenting blades of roughly fragmenting blade rotary structures so that rotation of the roughly fragmenting blade rotary structures is kept to the initial drive state. A roughly fragmenting blade (2) has a recessed portion (27) in a side surface of a roughly fragmenting blade main body having an outer peripheral edge formed with a blade portion (22). This recessed portion is formed in an annular manner in an intermediate region that is on the inner side in the radial direction with respect to the blade portion and is outside a bearing region. The recessed portion is for facilitating removal of cut fragments, i.e., for securing a clearance wider than the width of a cutting portion formed by the blade portions of the opposing roughly fragmenting blades when the roughly fragmenting blades are mounted to a roughly fragmenting blade rotary structure. The recessed portion is formed in one side surface or both side surfaces of the roughly fragmenting blade main body, depending on the construction and installment location of the roughly fragmenting blade rotary structure.

Title: Data network computing device call processing
Inventor: MCNIFF PETER GERALD
IPC: H04M3/533
Filed: 1999-09-16
Abstract: A telecommunications service node is connected to a data network using a packet data protocol and a telephone network using a circuit switched protocol. The service node is also connected to a wireless roaming network using the IS-41 signaling protocol. The service node stores status information, including location and registration information, for mobile computing devices connected to the data packet network. The location information includes a temporary data network address for visiting mobile computing devices. The service node manages voice calls to and from the mobile computing devices. If a call is received to a mobile computing device which is not registered, the service node will attempt to connect the call to a wireless telephone associated with the mobile computing device, or a predefined destination established as a preference by the user. In the case of a voice call between a telephone connected to the telephone network and a mobile computing device connected to the data network, the service node acts as a a gateway and translates between the data packet protocol and the circuit switched protocol. A personal information manager executing in a mobile computing device may be used for managing call processing functions of the mobile computing device.

Title: Fluorescence based liquid core waveguide
Inventor: LANGEBRAKE LAWRENCE C
IPC: G01N21/03
Filed: 1999-12-22
Abstract: A liquid core waveguide (10) for fluorescence spectroscopy is provided.  According to one version of the present invention, a substantially cylindrical support tube (30) is provided, having a substantially constant outer diameter, and a flexible tube (12) is wrapped in contiguous windings about the outer surface of the support tube (30) to form a tight coil about the support tube (30) which is configured of material that is transmissive of light in the relatively short wavelength range which is used to excite the molecular material in the flexible tube (12). This feature enables the flexible tube (12) to be wound tightly about the support tube (30) without crimping (thereby to form the liquid core waveguide into a compact package), and enables light in the relatively short excitation range to be effectively transmitted through the support tube (30) and into the flexible tube (12).
