Abstract:
Disclosed are systems and methods enabling a user to select optimal parameters for a printing job. The systems and methods disclosed are directed to facilitating the adjustment of printing parameters based upon at least the knowledge of a particular aspect of a printing environment (e.g., printer) and further including the ability to dynamically adjust parameters in relation to dynamically adjustable parameters, wherein the parameters may be determined as a function of other specified parameters.
Abstract:
A directory event system for providing timely event notifications of each data manipulation of a master directory database and for providing timely event notifications of each corresponding data replication to a replicate directory database is disclosed. The directory event system includes an event master server, one or more event service servers, and one or more event client servers. For an event client server having directory clients in electrical communication with the master directory database, the event master server provides an event notification to the event client server in response to a data manipulation of the master directory database by a directory service provider server. The master directory clients can immediately poll the master directory database for the manipulated data upon receipt of an event notification from the event client server. For an event client server having directory clients in electrical communication with the replicate directory database, the event master server provides an event message to an event service server in response to the data manipulation of the master directory database by the directory service provider server. The event message includes the event notification and the sequence number, and the event service server provides the event notification to the event client server upon a replication of the sequence number within the replicate directory database. The replicate directory clients can poll the replicate directory database for the manipulated data upon receipt of the event notification from the event client server.
Abstract:
An adaptor is provided for a games console which allows users to gain access to interactive television services through the games console. The adaptor includes a television tuner for receiving broadcast television channels, a communications controller which controls communications between the adaptor and the games console and an interface for interfacing the adaptor to the games console. In a preferred embodiment, the adaptor also includes a hard disc for storing video data and for storing game history data. The adaptor may also include a modem via which the user can gain access to remote servers connected to a data network.
Abstract:
A dispenser (10) for dispensing a mixture (6) of a first flowable material (4) and a second flowable material (5) has a container (12) having a first chamber (20) and a second chamber (30). The first chamber (20) is adapted to contain the first material (4) and the second chamber (30) is adapted to contain the second material (5). The dispenser (10) further comprises a first membrane (50a) separating the first and second chambers (20,30), and a second membrane (50b) connected to the container (12) proximate the second chamber (30). Pressure applied to the first membrane (50a) fractures the first membrane (50a) wherein the first flowable material (4) and the second flowable material (5) mix to form a mixture (6). Pressure applied to the second membrane (50b) fractures the second membrane (50b) to dispense the mixture (6).
Abstract:
A file is striped across multiple filers, file servers or other devices, to create a sparsely striped multi-component file. Each filer stores one sparse component. In particular, each component physically stores only those stripes allocated to that component. The other stripes are represented as holes. Thus, instead of contiguously packing each component's stripes at the block level, each component is a file having the same logical structure. A component of a sparsely striped multi-component file can be easily converted to a mirror by filling in its holes. Similarly, a mirror can be easily converted to one component of a sparsely striped multi-component file by removing or ignoring it unallocated stripes. In either case, the layout or logical of the component does not need to be reconfigured.
Abstract:
An apparatus includes a computing node and a metadata server. The computing node may transmit a request to open a file to the metadata server, which may provide a corresponding file identifier to the computing node. The computing node may use the file identifier to directly access the storage storing the file. In one embodiment, the storage may be an object-based storage. The storage may receive the file identifier with an access command and may perform the mapping from file identifier to storage blocks internally. Thus, accesses to the storage may be performed on an arbitrary boundary within the file. In other words, the entire block including the data needed by the computing node may not be transferred to the computing node. Instead, the storage may select the data requested from the file (e.g. via an offset and a number of bytes or some similar mechanism) and return that data to the computing node.
Abstract:
Dispensing apparatus is provided which includes a reservoir for containing a liquid therein which is supported by support means in use. The reservoir has an opening into which valve means are located. The valve means are movable between an open condition, wherein a user can dispense the liquid from the reservoir, and a closed condition, wherein the opening is closed. The valve means are a spaced distance from and separate to the support means. In addition, the reservoir is provided with means to allow releasable engagement with the support means, thereby allowing the reservoir to be located with and removed from the support means as and when required.
Abstract:
A system and method for synchronizing mirrored and striped disk writes. A data storage system may include a client computer system coupled to a first data storage device and a second data storage device and configured to transmit a first data write request. The first storage device may be configured to transmit a sequence number to the client computer system in response to receiving the first data write request. The client computer system may be further configured to transmit a second data write request including the sequence number to the second storage device. The second data storage device may include a counter and is configured to compare a current counter value to the sequence number. If the counter value is equal to the sequence number, the second storage device stores the data bytes corresponding to the second data write request and increments its counter.
Abstract:

Abstract:
Systems and methods are provided for detecting failure in clamping of a material and/or firing of a staple into a clamped material and indicating such failure to a user on a user interface. The system and methods are particularly suited for use with end effectors having closing and/or firing mechanisms coupled to an actuator. By monitoring a driving parameter of an actuator that effects the clamping and/or firing, the systems and methods provide an indication of failure in response to the monitored drive parameter. In some embodiments, an indication of failure is output when the monitored drive parameter is outside an acceptable range of desired driving parameters during clamping and/or firing. The disclosed systems and methods are particularly beneficial when used for minimally invasive surgery.
