  • Publication number: 20250341853
    Abstract: A computer system has processing circuitry to control a force feedback unit to progressively increase a force feedback applied to the input device in response to a manual maneuvering of the input device towards a virtual stop position being defined in between an equilibrium position and a mechanical end position of the input device. The virtual stop position is a software-defined set point acting as an intermediate trigger for the input device. The force feedback is progressively increased until it reaches a maximum force feedback at the virtual stop position; and control the force feedback unit to reduce the force feedback applied to the input device at the virtual stop position in response to a force of a manual maneuvering of the input device exceeding the maximum force feedback value.

  • Patent number: 12436532
    Abstract: A method to control a marine vessel comprising two or more drive units. The method involves registering an operating command indicating a requested sideways or bow bollard push function; detecting a current vessel position; registering the current vessel position as a desired vessel position; executing the requested bollard push function; and monitoring the current vessel position in order to detect a deviation relative to the desired vessel position. If it is detected that a deviation between the desired vessel position has exceeded a predetermined value, then the requested bollard push function is deactivated. The disclosure further relates to a control unit arranged to control a marine vessel and a marine vessel comprising such a control unit.

  • Patent number: 12346114
    Abstract: An operating command indicating a requested vessel direction and plotting a course represented by a reference line for the requested vessel direction from an initial position is registered. It is then monitored if the vessel has deviated from the reference line and if a deviation from the reference line is detected, then a value for current vessel speed is detected. The detected vessel speed value is compared to a predetermined reference speed value to determine if the current vessel speed value is within a high speed interval or a low speed interval relative to the reference speed value. Depending on the determined speed interval the vessel is controlled according a low speed control strategy; or a high speed control strategy in order to move the vessel from a current vessel heading to the reference line and the requested vessel direction.

  • Publication number: 20250136260
    Abstract: A maneuvering device for controlling navigation of a marine vessel is provided. The device has an input source movable between an equilibrium position and at least one displaced position, A variable resistance device adjusts a movement resistance of the input source. A control unit controls the variable resistance device by: obtaining a requested release input of the input source to move from the displaced position towards the equilibrium position, obtaining a longitudinal speed of the marine vessel, and controlling the variable resistance device to adjust said movement resistance of the input source based on the requested release input and the longitudinal speed.

  • Patent number: 8453493
    Abstract: A trace gas sensing apparatus includes a cathode, an anode, a vacuum enclosure, and a membrane. The anode coaxially surrounds the cathode, wherein the cathode and the anode define an annular ionization chamber. The vacuum enclosure surrounds the cathode and the anode and includes a gas inlet fluidly communicating with the ionization chamber. The membrane is coupled to the gas inlet in a sealed manner and is permselective to trace gas. The apparatus may further include circuitry for applying a negative voltage potential to the cathode and for measuring an ion current signal generated by the cathode, and a magnet assembly for generating a magnetic field in the ionization chamber. The cathode may include an elongated member located along a longitudinal axis, and first and second end plates orthogonal to the longitudinal axis.

  • Publication number: 20070219972
    Abstract: Embodiments of the present invention generally provide a system, method and article of manufacture for managing federated queries. In general, the availability of one or more databases targeted by a federated query may be determined prior to running the federated query against the targeted databases. In response to determining one or more of the targeted databases are unavailable, a user may be notified. The user may also be presented with options for running the federated query. The options may include being notified when all of the targeted databases are available, automatically running the federated query (in the background) when all of the targeted databases are available, and modifying the query to run against currently available databases.

  • Publication number: 20060150079
    Abstract: The present invention generally provides methods, systems, and articles of manufacture for managing an annotation system that includes storing annotations for a document family, i.e., a series of versions of a data source. Annotations created for one version of the data source may be viewed in context from both subsequent and prior versions of the same data source. Embodiments of the invention associate annotations with both a data source “family identifier” as well as a “version identifier.” Other than adding a family ID to the data source, the data source remains unchanged. The family ID is maintained across different versions of the data source, whereas version IDs are determined for a specific version of the data source. Version IDs can be constructed from each data source directly, and do not need to be stored.

  • Publication number: 20050209989
    Abstract: Methods, systems, and articles of manufacture for proving global annotation services are disclosed. Global annotations are used to annotate a data element independently from the internal representation of a data element employed by a particular software application. Data elements are normalized into a form used by a global annotation system to identify the data element, and corresponding global annotations, independent from the application in which the data element may appear. An annotation cache may be used to store the global annotations that have been created for a particular data source, improving the efficiency of the global annotation system.
