Chargrid: Towards Understanding 2D Documents.

Abstract: We introduce a novel type of text representation that preserves the 2D layout of a document. This is achieved by encoding each document page as a two-dimensional grid of characters. Based on this representation, we present a generic document understanding pipeline for structured documents. This pipeline makes use of a fully convolutional encoder-decoder network that predicts a segmentation mask and bounding boxes. We demonstrate its capabilities on an information extraction task from invoices and show that it significantly outperforms approaches based on sequential text or document images.

Gesture control system

Abstract: A control system basing on the use of gestures and functioning especially in mobile terminals. The gesture control system is provided with a general purpose interface (320) with its commands for applications (310) to be controlled. The processing software (330) of the gesture signals includes a training program (331), the trained free-form gestures made by the user being stored in the gesture library, and a recognizing program (332), which matches a gesture made by the user to the stored gestures and chooses the most similar gesture thereof. Gestures can hence be used as commands for controlling any application configured or programmed to receive the command. One and the same application functions in different models of mobile terminals without matching, and in a certain mobile terminal all applications can be run, which applications use specified interface commands. The application (310) can be e.g. a game or an activity being included in the basic implementation of a mobile terminal.

Flexible cover for a mobile telephone

Abstract: A mobile telephone comprising : an engine assembly comprising a display and a plurality of switches; and a flexible cover overlying, without an intermediate rigid cover, and snugly fitting the engine assembly and comprising an aperture aligned with the display and an integrated keypad, for user input, aligned with the plurality of switches.

Method and Apparatus for Multi-Item Searching

Abstract: An approach is provided for multi-item searching. A searching platform receives an input at a device for specifying one or more search criteria. The searching platform then causes, at least in part, a search for one or more services based, at least in part, on the one or more search criteria, and a presentation of a user interface including an animation based, at least in part, on the search, one or more results of the search, the one or more services, or a combination thereof.

Power supplies for rf power amplifier

Abstract: Switched-mode power supplies (SMPSs) and their control methods for radio frequency (RF) power amplifiers in bat- tery-powered wireless transmitter devices. According to embodiments of the invention, a Boost-type SMPS and a Buck-type SMPS in cascade connection are controlled so that high efficiency is maintained for various loads and transmission power levels. The Boost SMPS and the Buck SMPS can be controlled based on the mode of operation of the transmitter, such as the actual battery voltage, the needed output power, the selected frequency band, the selected RF power amplifier (PA), the selected modulation method of the transmission signal, and/or the selected PA voltage control method, such as the envelope elimination and restoration (EER) technique, the envelope tracking (ET) technique, or the power-level tracking (PT).
