Abstract: A method for operating an elevator system includes a trusted device that creates an authentication data packet having a unique, periodically changing code based on the current time. A mobile device sends a mobile request message to a server including the request for the operation of the elevator system and the authentication data packet. A server verifies the authenticity of the mobile request message based on the authentication data packet included in the mobile request message and, after the authentication data packet has been verified, sends an instruction message to the elevator controller.

Abstract: A method and a system for live broadcast of digital content to a user switching between one or more electronic devices are provided. Each electronic device is connected to a network. The user makes a request to switch the live broadcast of the digital content from a first electronic device to one or more electronic devices in the network. The live broadcast of the digital content on the first electronic device is suspended based on the request from the user. The first electronic device informs at least one electronic device in the network to pre-emptively store the live broadcast of the digital content. The live broadcast of the digital content is then resumed on the one or more electronic devices, based on another request from the user.

Abstract: A mobile station (201) receives (301) a transmission from a remote source (such as, but not limited to, a reference server (206)) comprising information regarding downloadable content. This information can comprise, in a preferred approach, addresses that can be used to download corresponding selections of downloadable content. This information can further comprise, in a preferred approach, characterizing information regarding at least some of the downloadable content selections identified via such addresses. In a preferred approach, such a mobile station can then also access (302) locally developed information regarding downloading constraints of interest and then make determinations (303) regarding when to automatically download at least a portion of at least one of the selections of downloadable content as a function, at least in part, of both the characterizing information as was received via the aforementioned transmission and the locally developed information regarding relevant downloading constraints.

Abstract: A memory-based collaborative filtering algorithm is optimized for large numbers of users by employing a personalized location-based data partitioning method that allows the system to scale even for very large datasets. Collaborative filtering then takes place on the scaled dataset.

Abstract: A system and a method for recording a broadcast being displayed on a mobile device. The system includes a mobile device (102), a server (104), and a Digital Video Recorder (DVR) (106). The mobile device receives and displays a broadcast. Further, the mobile device generates a first information pertaining to the broadcast and sends it to the server. The server, on receiving the first information, generates a second information, and then sends the second information to the DVR. The DVR, on receiving the second information from the server records the broadcast.
