Abstract: A system estimates the part of a current content page that is currently visible on a user screen. A movement detection unit detects movement of the content page within the user's browser, and an estimator infers whether a particular content item of interest is within the currently visible area. The movement detection unit in one version detects operating system directives to find out whether the user is scrolling etc through the page. Alternatively an identifiable point is placed on the content item and continual measurement is made between identifiable point in the content and a point in the currently visible area. The system is useful for providing statistical data about the effectiveness of advertisement placement within web pages.

Abstract: Methods of combining semi-persistent resource allocation and dynamic resource allocation are provided.  Packets, such as VoIP packets, are transmitted on the uplink and downlink using respective semi-persistent resources. For each mobile device, awake periods and sleep periods are defined.  The semi-persistent resources are aligned with the awake periods so that most of the time the mobile device can turn off its wireless access radio during the sleep periods. In addition, signalling to request, and to allocate, resources for additional packets are transmitted during the awake periods, and the resources allocated for the additional packets are within the awake windows.

Abstract: A portable expandable cooking device is disclosed which can be readily be used on a barbecue or heated indoor cooking surface, to cook small meat pieces or vegetables on skewers. The invention provides an improved collapsible and expandable frame that is used directly on barbecue surfaces to grill Shish Kebabs of different lengths. Shish Kebabs' of smaller lengths are also referred to as spieduccis and spiedinis. The front wall and back wall structures are connected to each other via expansion side plates to form a frame which can be adjusted to different lengths and locked in position to accommodate shish kebabs of,various skewers lengths. The front wall and the back wall have slots which maintain to locate a plurality of skewers' and stabilize the skewers' in locked or fixed width position on the frame structure and also locate the skewers' above the grill surface so that the skewered meat and vegetables do not touch the overheated surface of the grill. This allows the frame and skewers' to be easily moved around on the grilling surface as a single unit. The front wall and the rear wall has an integrated bent handle structure on the frames adds safety to the unit and allows the unit to be collapsed or expanded ergonomically. The frame structure lifts the skewered meat and vegetables form the hot grill surface thus minimizing the burned spots that would have occurred in the event of the meat touching the overheated grill.

Abstract: Based on the idea of reusing grey water generated by the washhand basin and other sanitary appliances in the bathroom, with the exception of the toilet, storing the grey water in a tank wherefrom the cistern of the toilet is supplied when it is necessary, the invention consists of situating from the grey water intake connector (1) and in a main pipe (5), a particle filter (9), a flow switch (11), a circulation pump (14), an ozone injector (16) with its corresponding water recirculation pump (15), and a check valve (18), the flow switch (11) sending information to a programmable automaton (12) which in turn controls both the aforementioned pumps (14 and 15) and the electrovalve (8) of a secondary pipe (6) wherethrough the grey water is evacuated, by means of the outlet (7) to the building downpipe, when the storage device is full.   It is thereby achieved that the toilet cistern receives perfectly filtered water, to avoid obstructions or loss of sealing in the closure system thereof, and that furthermore the water remains free of bacteria and other microorganisms, which are eliminated by the ozone injector (16).

Title: Part load combustion cycles
Inventor: MCGUIRE L ALLAN
IPC: F02C3/30
Filed: 2008-09-02
Abstract: The part load method controls delivery of diluent fluid, fuel fluid, and oxidant fluid in thermodynamic cycles using diluent, to increase the Turbine Inlet Temperature (TIT) and thermal efficiency in part load operation above that obtained by relevant art part load operation of Brayton cycles, fogged Brayton cycles, or cycles operating with some steam delivery, or with maximum steam delivery. The part load method may control the TIT at the design level by controlling one or both of liquid and/or gaseous fluid water over a range from full load to less than 45% load. This extends operation to lower operating loads while providing higher efficiencies and lower operating costs using water, steam and/or CO2 as diluents, than in simple cycle operation.

Abstract: Multimedia message service (MMS) communications directly between mobile stations avoid interactions with a MMS Center (MMSC). In the examples, the originating station sends a short message service (SMS) message notifying the destination mobile station of the availability of the MMS message. This message provides an IP address of the originating station and an identifier for retrieval of the MMS message. In response, the destination mobile station sends back a packet message using the IP address of the originating station and the identifier, to request retrieval of the MMS message. The request message also includes an IP address for packet communication with the destination station. The originating mobile station uses that address for packet communication of the MMS message to the destination mobile station. In the examples, the destination station sends the MMS message to a regional node, for possible transcoding and/or to facilitate billing.
