Abstract: A system for capturing, organizing, and storing handwritten notes includes a plurality of fluorescently colored boundary markers. The boundary markers are configured to be positioned on a writing surface. An image of the writing surface with the fluorescent markers thereon is captured and the fluorescent colored boundary markers in the captured image are detected. A virtual boundary in the captured image is identified based on the positions of the fluorescent colored boundary markers. A portion of the captured image within the virtual boundary is unwarped to produce an unwarped image.

Abstract: Illustrative embodiments of the system allow users to write handwritten notes, such as to-do items and calendar events, and have them converted into online objects and actions by a handwriting parser engine. The handwriting is processed and converted into commands that execute online actions or create online objects, which can be local to a device (e.g., creating a calendar entry in a calendar program) or can involve actions using or taken over a communication system (e.g., creating a calendar entry in an online calendar, making a purchase from an online service, transmitting a text or email message, etc.).

Abstract: A modular notebook system includes a cover having a plurality of surfaces. The system also includes a binding coupled to the plurality of surfaces via a flexible and/or foldable material. The binding forms a magnetic spine by having at least one magnetic pad configured to receive a magnetically attractive binding element.

Abstract: A method of reusing a notebook provides a notebook having a synthetic-paper page. The method also provides a thermochromic ink pen which, when used to write on the synthetic paper page, leaves thermochromic ink markings. The method further provides a moisture carrier configured to have a liquid diffused therein. The moisture carrier is configured to erase the thermochromic ink markings from the synthetic-paper page by contacting the thermochromic ink markings when the moisture carrier is moist. The method then writes with thermochromic ink on at least a portion of the synthetic-paper page. Liquid is diffused in the moisture carrier, and the portion of the synthetic-paper page having the thermochromic ink is wiped with the moist moisture carrier, such that the thermochromic ink is erased from the synthetic-paper page.

Abstract: A system for capturing, organizing, and storing handwritten notes includes a plurality of boundary markers. The boundary markers are configured to be positioned on a writing surface. Furthermore, the plurality of boundary markers have a fluorescent color. The system also includes a tangible non-transitory computer readable medium encoded with instructions which, when run on a camera-equipped computing device, causes the camera-equipped computing device to execute processes. The processes include capturing an image of the writing surface with the fluorescent markers thereon. The processes also include detecting the fluorescent colored boundary markers in the captured image. Additionally, the processes include identifying a virtual boundary in the captured image based on the positions of the fluorescent colored boundary markers. The processes then unwarp a portion of the captured image within the virtual boundary to produce an unwarped image.

Abstract: Handwritten notes are captured organized and stored by a system as a digital representation. The system includes a notebook having a set of pages, wherein each page has placed thereon a folio identifier representation, such representation including a page identifier. The system also includes a non-transitory computer readable medium encoded with instructions, which, when running on a camera-equipped computing device at a time when the camera thereof views a page of the notebook, cause performance of processes. The processes performed by the instructions include: processing an image associated with the page, detecting and decoding the folio identifier representation to provide a page identifier for the page, and if the image has not been previously captured, then capturing the image of the page and saving the image in an image store.

Abstract: A writing utensil holder for attachment to a notebook includes a plate having a notebook attachment portion and a writing utensil holding portion. The notebook attachment portion is configured to attach to a notebook such that the notebook attachment portion is inside of a perimeter of the notebook when the notebook attachment portion is attached to the notebook and the holding portion is outside of the notebook perimeter when the notebook attachment portion is attached to the notebook. The writing utensil holder also includes a securing implement secured to the holding portion and configured to hold a writing utensil between the securing instrument and the holding portion such that the writing utensil is outside of the notebook perimeter.

Abstract: A reusable notebook is used with heat-erasable ink. The reusable notebook includes a binding configured to hold a plurality of pages, at least one cover, and at least one ready indicator. The ready indicator is configured to indicate that at least one page in the notebook has reached at least a critical temperature. The critical temperature is a predetermined minimum temperature that is sufficient to erase thermochromic ink on the page(s). The indication occurs when the ready indicator is at a temperature equal to or above a predetermined minimum temperature referred to as the ready temperature. When the ready indicator is at or above the ready temperature, the critical temperature of the at least one page is reached.

Abstract: An internal combustion engine in which each cylinder is connected to sources both of air and of fuel held as a gas under pressure and in which the compression stroke, during which a full charge of air is drawn and compressed, is substantially completed before the fuel charge is then admitted and the mixture ignited to start the subsequent power stroke. The fuel may be admitted through a unit doubling as admission valve and igniter, and conventional diesel or gasoline-fuelled engines may be converted by designing that unit to fit into the conventional injector or spark plug holes. The compressed gaseous fuel may be methane, or other natural gas. The invention includes both stationary and mobile engines, especially automobile engines, and methods of operating them.
