Title: Method and system for representing hierarchical time-based data structures and to extract information therefrom
Inventor: HILL RAYMOND
IPC: G06F16/185
Filed: 1997-04-15
Granted: 2005-07-26
Abstract: A method and system for representing hierarchical time-based data structures and to extract information therefrom comprises means to create a container, the container having one or more layers within which data elements are arranged along the container axis and to examine the container to produce virtual static graphs which represent active data elements and their interconnections within time durations represented within the container. The data elements in the container can change between active and inactive states with time and the connections between data elements can also change with time and the container represents this information. A set of constraints is defined for the container such that interconnections between data elements only occur between data elements in different layers. Specifically, a data element can only receive input from one or more other data elements which are in lower levels and a data element can only provide output to one or more data elements which are in higher levels. Transitions in a lower layer, representing changes in the active status of a data element, are propagated to each higher layer, such that a higher layer can never have less transitions that a lower layer. Each layer includes a record of which data element outputs are available in the layer at all times. When a request for information relating to the active data elements and their interconnections within a specified time period is received, the container is examined to produce a virtual static graph representing the minimal set of active data elements and their interconnections with the specified time.

Abstract: A method and apparatus are set forth which enables a gas chromatographic column output to be connected with a pulse discharge chamber in which chemically bound chlorine in volatile organic or inorganic samples is measured. A spark discharge is formed in the chamber to ionize and excite helium molecules to a metastable state. In turn, that transfers excitation to a trace of krypton gas in the chamber which is ionized, and the ionized krypton then preferentially binds with chemically bound chlorine. The latter binding occurs with the liberation of a photon centered at about 222 nanometers thereby defining a spectral region of interest which is measured by a photomultiplier tube to quantify chemically bound chlorine.

Title: Absorbent article with clean appearance and capacity signal means
Inventor: HENNESSY SHANNON JULIA
IPC: A61F13/00
Filed: 1996-09-13
Granted: 2002-01-22
Abstract: An absorbent article, such as a sanitary napkin, comprising a topsheet, a backsheet, and an absorbent core is described. The absorbent core comprises an acquisition member, a storage/distribution member, and an indicator member.  The absorbent article further has a longitudinally oriented middle region defined by the storage/distribution member and a pair of longitudinally oriented side regions that lie laterally outboard of the middle region. The acquisition member is disposed on the storage/distribution member and the indicator member is disposed, at least partially, in the side regions. The storage/distribution member has a higher capillary suction than the acquisition member such that absorbed bodily fluids are drawn from the acquisition member into the storage/distribution member providing a clean appearance. The capillary suction of the storage/distribution member is also higher than the capillary suction of the indicator member so that the indicator member is not noticeably stained until the absorbent capacity of the storage/distribution member is substantially exhausted thus providing a signal that it is time to change when such staining becomes apparent.

Title: Oa&m system
Inventor: FREDINE ERIC
IPC: H04Q3/00
Filed: 1998-05-14
Granted: 2001-02-20
Abstract: An OA&M system is provided for a network communication core having a switch, a controller, and a core configuration memory. All configuration information which is static (i.e., information which remains the same regardless of the configuration of the core) is placed off-core in a map file. Because of this, requests for information on the configuration of the core may often be satisfied without the need to query the core, thereby reducing core load. Further, this static information in the map file allows validation of requests for dynamic configuration information as well as requests for reconfiguration of the core. In other words, the static information assists in ensuring that requests are proper. The static information in the map file is presented as "list", "attribute", and "choice" features. This presentation facilitates the making of OA&M requests by a user. The features become arguments of functions in order to generate OA&M requests to the controller. Each function received by the controller is converted to instructions for the core by an interface and a map file in the core. The features in the off-core map file are organised into a hierarchical tree (a feature tree) and the off-core map file may be accessed by a browser program of a personal computer so that levels of the tree may be displayed, thereby facilitating quick configuration requests.

Abstract: A tool for conducting gravimetry survey downhole in an earth formation includes a pressure vessel which houses a gravity sensor that is supported by a gimbal.  The gravity sensor is aligned with vertical before taking gravity measurements by a first stepper motor and a second stepper motor.  The first stepper motor incrementally rotates the gimbal about the pivot axis of the gimbal while the second stepper motor incrementally rotates the gimbal about the longitudinal axis of the pressure vessel.  The stepper motors are controlled by an electronic processor that responds to signals from an accelerometer assembly that measures the inclination of the pressure vessel with respect to vertical.  An elevator mechanism translates the gravity sensor from one station to the next inside the pressure vessel to make gravity measurements and an optical encoder monitors the position of the gravity sensor inside the pressure vessel.

Abstract: Optical elements utilize multimode interference in a piece of an optical fiber of multimode type having a core in the shape of a ring or a tubular structure. Such a fiber can be compared to a planar waveguide, the core of which has been bent about a longitudinal axis located at some distance from the core. Such an optical fiber can be optically excited having an excitation centre in a point on or at the annular core by coupling from a single-mode fiber. Then different optical propagation modes are excited having approximately regular relations between their phase velocities so that, for example, for a suitable length of the fiber piece a light intensity is obtained in the other end of the fiber piece which is an approximate reflected image of the light intensity supplied at the input end of the fiber piece. Such an optical element can, for example, be used as a filter or as a passive 1 × N-coupler, where in the latter case the length of the fiber piece is adapted so that an N-fold image of the supplied light intensity is obtained at the output end of the fiber piece.
