Abstract: A method that allows one to mark information with a pencil or ball point pen on a material and have the marked information represent answers to questions or responses to queries that may be read while the material is contained in an envelope. The material may be any cellulose type product, i.e., paper, cardboard, chipboard, wood or plastic, fabric, animal hide, etc. The marked entered information may be corrected by erasing the written information with an eraser and writing new information on the paper with a pencil or ball point pen.

Abstract: A system for providing a selected digital medium to a customer on request. The selected digital medium has a selected title recorded thereon. The system includes a data storage device that stores a digital copy of available titles, a digital recording device, a blank digital media storage unit for storing blank digital media, a digital media inventory storage unit, and a digital media dispenser. The digital media inventory storage unit stores for available titles a predetermined number of digital media having a particular title recorded thereon. After the selected digital medium is requested by the customer, the digital recording device receives a digital copy of the selected title or another title and records the selected title or other title onto one of the blank digital media, which is then stored in the digital media inventory storage unit.

Abstract: A method for the secure reading of answers to questions or quires by an RFID reader that were made by marking answers with a pencil or ballpoint pen on a material. The questions are securely transmitted because an identification on the material indicates the order of the transmitted questions or from which electrical contacts the answers correspond to.

Abstract: In a printer system where a print head is used to print on a flat material moving on a surface along a moving direction, a first creasing surface and a second creasing surface disposed on different sides of the flat material are used to make a crease on the flat material. The first creasing surface is mounted on a housing and the second creasing surface is disposed along the length of a track substantially perpendicular to the moving direction. The first and second creasing surfaces are substantially complementary to each other such that when these creasing surfaces are moved closer to each other, they cause the flat material to bend. A movement mechanism is then used to move the housing along the track so that the bending of the flat material forms a crease from one side of the flat material to the opposing side.
