Abstract: The invention concerns a method for making ammonium dinitramide from guanylurea dinitramide in one single process step. Guanylurea dinitramide is reacted with an ammonium sulfate in a reaction solution comprising water and acetone and an ion exchange gives ammonium dinitramide. By using acetone the yield is increased compared to known processes as formed guanylurea sulfate is poorly soluable in a water-acetone solution and precipitates, while guanylurea dinitramide has higher solubility in the solution than in only water. The guanylurea sulfate precipitate formed in the reaction solution that contains acetone is less sticky than if formed in water or in a water-alcohol solution and therefore easier to filter off. The use of acetone also allows lower process temperatures to be used than in previously known methods for producing guanylurea dinitramide.

Abstract: Various aspects provide for “parking” an apparatus in a “parking position.” A parking position may be a configuration of an apparatus that minimizes damage resulting from extended exposure during periods of inactivity. An apparatus may comprise a marine apparatus, which may be configured to be disposed in an environment comprising saltwater, salty air, brackish water, freshwater, and the like. An apparatus may comprise a propulsion system (e.g., for a ship) and/or a steering system. Some aspects include a water jet based propulsion system having a scoop and a nozzle operable to redirect the water jet, providing a range of forward/backward and port/starboard thrusts. A control cylinder and/or a linkage may be parked in a configuration that segregates damage incurred during periods of inactivity to portions of an apparatus not needed for normal operation.

Abstract: A computer system has at least one memory and at least one processor. The at least one memory stores one or more options. Each option is associated with a gaming application provided to a user device. Each option has a respective identifier and a respective weight. The at least one processor retrieves one or more of the options from the at least one memory. The weight provides a weighting for each option in dependence on previous selections of that option.

Abstract: The invention concerns a method for making ADN from GUDN in one single process step. GUDN is reacted with an ammonium source (ammonium-sulfamate, ammonium-sulfate, ammonia) and an ion-change gives ADN from GUDN in one process stage. The advantages are that the process gives pure ADN without potassium contaminants and that a smaller amount of solvent is necessary.

Abstract: Passive presence information for a first user of a service, such as a conversation service, is obtained by analyzing user activity logs. This is performed upon request for a second user. Thus lightweight presence information can be obtained without requiring the higher overhead required in a conventional Internet Protocol Multimedia Service (IMS) environment. Such a lightweight presence feature can enable other services including a conversation service that allows users to update a conversation object. Users can listen for updates to particular conversation objects, thus providing a simulated real-time push experience.

Abstract: A method for planning a treatment session of a patient and optimizing the treatment time for a treatment using a radiation therapy system includes a radiation therapy unit having a fixed radiation focus point. During an optimization of a treatment plan for a patient, a set of shots to be delivered to a plurality of isocenter positions within a target volume of a patient during a treatment session are determined and a beam-on time for each respective sector and state for each isocenter during which radiation is to be delivered are determined based on the treatment plan. For each isocenter position, sectors and states of respective sector are grouped in accordance predetermined rules with respect to beam-on times for respective state of the sectors, wherein sectors and respective states are aggregated for simultaneous delivery of radiation during a predetermined period of time.

Abstract: An embodiment of the present invention discloses a method for liquid transfer and a liquid disinfection apparatus for cleaning of objects, such as health care objects. The disinfection apparatus includes a chamber which is arranged to receive said objects for cleaning, a spray system including nozzles for distributing liquid in the chamber, and an outlet tank connected to a sewer system. The chamber is adapted to receive a liquid volume which is being circulated by the spray system including nozzles for cleaning of objects. In at least one embodiment, the disinfection apparatus further includes a rapid transfer port which is liquid flow connected between the chamber and an outlet tank so as to constitute an immediate transfer of the first volume from the chamber to the outlet tank, essentially without any tubing arranged between the chamber and the outlet tank.

Abstract: Techniques and apparatus for aggregating social network service (SNS) data are disclosed. In an example method for operating a computerized SNS aggregator having a plurality of account holders, identifiers for one or more external network-accessible SNS accounts associated with each of several account holders are collected and stored. An access token for each of the associated external network-accessible SNS accounts is collected and stored. Data-sharing relationships between pairs of account holders having linked accounts within the SNS aggregator service are identified. Subsequently, one or more account holders having a data-sharing relationship with a first account holder are identified. One or more external network-accessible SNS accounts for each of the other account holders are accessed, using the corresponding stored access tokens. Finally, a data feed for the first account holder is assembled, using data items retrieved from the external network-accessible SNS accounts for the other account holders.

Abstract: In detecting the identity of a person currently using a computer (100) and in particular for detecting whether the person is the intended or authorized user of the computer previously established user patterns of users as stored in a database (4) are matched, in comparators (9), with data of the person's interactions through the computer. The interactions are detected by a monitoring module (2) that in testing modules (7) can process data of the interactions and storing them in buffers (8) to be used by the comparators. Such data can include data of interactions that happen directly after each other and can also include one or more time characteristic of each detected interaction.

Abstract: A method and an enhanced voice mail system for subscribing to RSS (Really Simple Syndication) feeds on behalf of a user are provided. The enhanced voice mail system subscribes with RSS server(s) to obtain one or more RSS feeds for a user and further obtains the RSS feeds media content referred to within the RSS feeds. The received media content may be transcoded if needed, for example to adapt to the media format supported by the voice mail system, and then stored in the enhanced voice mail system. The later further notifies the user of the availability of the RSS feeds media content, possibly using e.g. SMS notifications. The voice mail system therefore enhances the user experience by extending its functionality beyond the simple handling of user-to-user voice mail messages. The user can then connect to their mailbox of the enhanced voice mail system and get access not only to voice mail messages left by other users, but also to RSS feeds media content.

Abstract: A method for sharing multimedia content protected by RM by a first subscriber with at least one second subscriber of a communication system comprises: receiving the protected multimedia content by the at least one second subscriber from the first subscriber, who previously received the multimedia content; and requesting a license key for unlocking the protected multimedia content by the at least one second subscriber; wherein requesting the license key allows for correlating the license key with the multimedia content. Furthermore, a method for tracking messages in a communication system comprises: protecting the messages through RM; granting a license key to unlock the protected messages upon request of a subscriber who has received the protected messages; and correlating the key with the messages so as to track the messages.
