Abstract: A text vectorizer is provided to compute vectors for respective text units. The text vectorizer computes a given vector for a given text unit by: (i) computing word vectors for respective words in the text unit; (ii) computing phrase vectors for respective phrases in the text unit; and (ii) combining the word vectors and the phrase vectors to produce the given vector for the given text unit. For a corpus of documents, the text vectorizer computes corpus vectors for the respective corpus documents. Search text is received, and, based thereon, the text vectorizer computes a search vector for the search text. Search scores are then computed for respective corpus documents by comparing the search vector with the corpus vectors of the respective corpus documents.

Abstract: A method is provided for controlling access to applications available on a second network by a plurality of client mobile communications devices on a first network, wherein the first network includes (a) a first database comprising (i) a product catalog which contains a listing of a subset of the applications available on the second network, and (ii) a set of service rules which governs access to any of the applications in the product catalog by the client mobile communications devices, (b) a second database which specifies the applications that have been activated for each of the plurality of client mobile communications devices, and (c) a network appliance which is in communication with the second database and which grants access by each of the client mobile communications devices to the respective applications specified as active for that device.

Abstract: A mobile communications device having a client installed thereon which establishes and maintains a connection between the mobile communications device and a network via a platform, wherein the connection utilizes a message protocol in which all messages between the device and the network are packetized, and wherein, while a first connection between the mobile communications device and the platform is available and a second connection between the platform and the network is available, the client establishes the connection when the mobile communications device is powered up and subsequently maintains the connection.

Abstract: A network access device is provided which includes a connector, a tangible, non-transitory computer readable medium, and a computer program stored in the medium. The connector is adapted to releasably engage a port in a mobile communications device, thereby bringing the network access device into electrical communication with the mobile communications device. The computer program contains suitable programming instructions which, when executed, provide the mobile communications device with broadband access to a network through an MVNO or MNO, subject to a predefined set of restrictions defined by a tenant of the MVNO.

Abstract: A method is disclosed for providing broadband communication services. The method comprises establishing a first entity which provides broadband wireless access to a network; and providing the broadband wireless access to a second entity on a white label basis through said first entity. The second entity distributes wireless mobile communications devices to third parties, and the wireless mobile communications devices are configured to establish broadband wireless access to the network through the broadband wireless access provided by the first entity to the second entity and under a private label applied by the second entity to the network access.

Abstract: A method includes expanding a first balloon distally of a gastro-esophageal junction, and contacting the first balloon to a proximal portion of a stomach. The method can be used for abdominal surgery, such as, for example, bariatic surgery (e.g., gastric bypass surgery), anti-reflux surgery (e.g., fundoplication), and other esophageal-related surgeries (e.g., Heller myotomy, hiatal hernia repair, and paraesophageal hernia repair).
