  • Publication number: 20070274868
    Abstract: A gas sensor arrangement for detecting a combustible gas comprises a detector wire in thermal contact with a catalyst and a compensator wire. The wires are in the form of pellet resistors (pellistors) and in a constant current bridge arrangement. An electrical circuit connected to the detector wire and to the compensator wire is arranged to detect a difference between the resistance of the detector wire and the resistance of the compensator wire to provide an output signal to indicate the presence of a combustible gas. The electrical circuit is 15 further arranged to derive a correction signal from a measurement of the resistance of the compensator wire for correcting the output signal for temperature variation. The ambient temperature is thereby measured using the voltage across the compensator wire. The correction can be implemented in hardware or software.

  • Publication number: 20070220874
    Abstract: The present invention broadly comprises a stator and clutch assembly in a torque converter. The stator has a segment radially disposed between stator blades and a stator axis. The one-way clutch has a plate connected to a hub. The segment forms a portion of the clutch and the stator is axially displaceable to control operation of the clutch. A displacement element urges the stator in a first axial direction. The stator is arranged to move in a second axial direction, opposite the first axial direction, in response to pressure from fluid in the torque converter. In some aspects, the displacement element is selected from the group consisting of a coil spring and a wave spring. In some aspects, the one-way clutch is arranged to disengage when the stator is sufficiently displaced in the first direction and to engage when the stator is sufficiently displaced in the second direction.

  • Publication number: 20070113031
    Abstract: Embodiments of the present invention provide an efficient manner to systematically remove data from a memory that has been transferred or copied to disk storage, thereby facilitating faster querying of data residing in the memory. In particular, memory containing data received from data sources is partitioned into a fixed quantity of buckets each associated with a respective time interval. The buckets represent contiguous intervals of time, where each interval is preferably of the same duration. When data arrives, the data is associated with a timestamp and placed in the appropriate bucket associated with a time interval corresponding to that timestamp. If a timestamp falls outside the range of time intervals associated with the buckets, the data corresponding to that timestamp is placed in an additional bucket. Data within the oldest bucket in memory is periodically removed to provide storage capacity for new incoming information.

  • Publication number: 20070062964
    Abstract: In accordance with the present invention, an easily openable container includes an elastic member that is connected to the container when the closure is in an open condition. Thus, the elastic member is at rest when the cover closure is open and spring-biases the closure to an open condition. When the closure is closed against the spring-biasing of the elastic material, the elastic member is stretched and held stretched when the closure in the front of the closure is engaged, such as by a snap closure or any other releasable connection. When the locking mechanism is released, the closure pops open by contraction of the elastic member.

  • Publication number: 20070025496
    Abstract: Artifacts in the reconstructed volume data of cone beam CT systems can be removed by the application of respiration correlation techniques to the acquired projection images. To achieve this, the phase of the patients breathing is monitored while acquiring projection images continuously. On completion of the acquisition, projection images that have comparable breathing phases can be selected from the complete set, and these are used to reconstruct the volume data using similar techniques to those of conventional CT. Any phase can be selected and therefore the effect of breathing can be studied. It is also possible to use a feature in the projection images such as the patient's diaphragm to determine the breathing phase. This feature in the projection images can be used to control delivery of therapeutic radiation dependent on the patient's breathing cycle, to ensure that the tumor is in the correct position when the radiation is delivered.

  • Publication number: 20060235891
    Abstract: A method and computer-readable medium are provided for storing files in an official file repository. According to the method, a generic interface is exposed that includes a first method for requesting that a file be stored in a file vault. A record series is maintained that identifies one or more document types that may be stored in the file vault along with a location for each file type within the file vault where files of the type should be stored. A call may be made to the first method including the file to be stored in the file vault. In response to the call, a location for storing the file in the file vault may be identified based on the contents of the record series. Once the location has been identified, the file is stored in the identified location if the file type is in the record series. If the file type is not in the record series or the necessary property values are not received with the call, the file is placed in a holding zone portion of the file vault.

  • Publication number: 20060218198
    Abstract: A method and computer-readable medium are provided for formula-based document retention. According to the method, a retention formula and a retention action are defined for one or more items. The retention formula is utilized to calculate a retention date for each item. The retention action specifies the action that should be taken on or after the retention date. The retention date for one or more items is initially calculated using the retention formula for the items. A retention service may be periodically executed to identify any items having a retention date earlier than the current date. If any items are identified that have a retention date earlier than the current date, the retention service recalculates the retention date for these items utilizing the corresponding retention formula. If the recalculated retention date for any item is still prior to the current date, the retention action for the item is executed.

  • Patent number: 7113953
    Abstract: A system and associated method write data from an in-memory database to a disk database in an efficient manner and with a relatively short lag time. The integration of data from in-memory to disk is achieved by limiting the operations of the in-memory database to insert only. The system shortens lag time by reducing the number of transactions required to transfer data from in-memory database to disk memory. The system compiles into an RDBMS, knowledge about the structure of the in-memory database, and then uses the end of the transaction callbacks from the RDBMS to keep the in-memory database and the disk memory in synch. The RDBMS includes a daemon that runs periodically to find records in the in-memory database that have not yet been written to the RDBMS, and then writes the found records to the RDBMS as part of a single transaction. If the transaction completes successfully, the in-memory database is updated to reflect which records have been “flushed” to the RDBMS.

  • Publication number: 20060202644
    Abstract: A linear accelerator comprises a series of accelerating cavities, adjacent pairs of which are coupled via coupling cavities, in which at least one coupling cavity comprises a rotationally asymmetric element that is rotateable thereby to vary the coupling offered by that cavity. A control means for the accelerator is also provided, adapted to control operation of the accelerator and rotation of the asymmetric element, arranged to operate the accelerator in a pulsed manner and to rotate the asymmetric element between pulses to control the energy of successive pulses. A beneficial way of doing so is to rotate the asymmetric element continuously during operation of the linear accelerator. Then, the control means need only adjust the phase of successive pulses so that during the brief period of the pulse, the asymmetric element is “seen” to be at the required position.

  • Publication number: 20060200468
    Abstract: A method and computer-readable medium are provided for generating usage rights for an item based upon rights to access the item. According to the method, a request is received at a document management system for an item stored in a library. In response to the request, access rights to the item for the requester are determined and usage rights are generated based upon the access rights. An encrypted file is then created that contains the item and the usage rights for the item. The location of the item in the library may also be included in the protected file. When an attempt is made to store the item back in the library, a comparison is made between the location where the item was previously retrieved from (as specified within the item) and the requested location in the library for saving the item. The item is only saved in the library if the two locations match.
