Abstract: A server system is communicatively connected to a plurality of computing devices and one or more databases. The server system receives one or more queries from a computing device. The one or more queries specify a data source. The server system determines a level of security applicable to a user of the computing device. The server system translates the one or more queries into one or more logical queries according to semantics of the data source, and transmits the logical queries to a query pipeline of the server system. The server system executes the one or more queries against a first database of the one or more databases to retrieve query results from the data source. The server system applies the determined level of security to the query results to obtain one or more data sets, and returns the one or more data sets to the computing device.

Abstract: A client device receives one or more inputs for generating a data visualization according to a data source. The device determines one or more requirements for generating the data visualization. The device sends a request to a network gateway that is communicatively connected to the client device and a plurality of data servers, and receives, from the network gateway, capabilities of each data server. The device determines, according to the received capabilities, that a first data server of the plurality of data servers includes a first set of capabilities that satisfies the requirements for generating the data visualization. The device sends, via the network gateway, one or more queries to the first data server and receives, from the first data server, one or more data sets from the data source. The device generates the data visualization according to the retrieved data sets and displays the data visualization.

Abstract: A system for capturing and reproducing handwriting. The writer employs a stylus or pen in combination with a digital writing tablet that captures the gestural movements of the stylus during writing, as well as the timing and rhythm of the strokes. A recognition engine analyzes the gestural movement data and produces a sequence of values identifying characters in a character set, as well as additional pictogram data which records the shape of non-character data written on the tablet. The recognition engine further generates ancillary data which further describes individual characters or groups of characters, specifying their size, slope, absolute position, applied stylus pressure, timing and rhythm, color, spacing, and other data that enables a rendering engine to select a font to represent the original handwriting and to further modify the selected font representation of the characters or groups of characters in a manner specified by the ancillary data.
