TL;DR: In this paper, an imaging device was used to produce digitized image data of one side of documents, like checks, as they were moved along a document transporter, and the system was designed to read, automatically, the "courtesy" or monetary amount of the documents from the digitised image data.
Abstract: A banking system in which this invention is used is disclosed. The system includes an imaging device which produces digitized image data of one side of documents, like checks, as they are moved along a document transporter. The system is designed to read, automatically, the "courtesy" or monetary amount of the documents from the digitized image data. Handwritten, courtesy amounts which have touching or overlapping characters or numbers must be separated or segmented prior to being subjected to character recognition. According to this invention, the digitized data is processed to "single out" image data which ostensibly contains data for more than one character. Special window "masks" are used to examine the image data (which is binary) to search for a potential joint between the "two characters". When the potential joint is found, potential segmentation vectors at different angles are examined to determine the preferred segmentation vector. The image data for more than one character is divided along the preferred segmentation vector and the divided image data is later subjected to character recognition.

TL;DR: In this article, a system and method for providing virtual spaces, where a character associated with a user can be manifested within instances of a plurality of the different virtual spaces is presented, where the character can be transferred by the corresponding user between instances of different virtual space and controlled by the user to interact with the different VMs.
Abstract: A system and method for providing virtual spaces, where a character associated with a user can be manifested within instances of a plurality of the different virtual spaces Since a single character can be manifested within instances of different virtual spaces, the character can be transferred by the corresponding user between instances of different virtual spaces and controlled by the user to interact with the different virtual spaces When the user transfers the character between instances of different virtual spaces (and/or different types of virtual spaces), various aspects of the character may persist between the different virtual spaces (and/or the different types of virtual spaces) This may provide an enhanced continuity to the character between the different virtual spaces

TL;DR: In this paper, a system for displaying a control object in which characters may be entered or edited via a character spin dial is presented, where each character and empty space in which a character may be inserted or edited is displayed in a separate cell within the control object.
Abstract: In association with an interactive television system, a system for displaying a control object in which characters may be entered or edited via a character spin dial. Each character and empty space in which a character may be entered is displayed in a separate cell within the control object. Each cell accepts entry or editing of characters therein via a character spin dial. The character spin dial is displayed to the user as an up arrow and a down arrow displayed above and below the cell, respectively. By manipulating a directional control on a remote control associated with the interactive television network in the up or down position, the user scrolls the character spin dial through a list of selectable characters until the desired character is displayed in the cell.

TL;DR: It is demonstrated that Charagram embeddings outperform more complex architectures based on character-level recurrent and convolutional neural networks, achieving new state-of-the-art performance on several similarity tasks.
Abstract: We present Charagram embeddings, a simple approach for learning character-based compositional models to embed textual sequences. A word or sentence is represented using a character n-gram count vector, followed by a single nonlinear transformation to yield a low-dimensional embedding. We use three tasks for evaluation: word similarity, sentence similarity, and part-of-speech tagging. We demonstrate that Charagram embeddings outperform more complex architectures based on character-level recurrent and convolutional neural networks, achieving new state-of-the-art performance on several similarity tasks.
