Abstract: An ink jet printer has a specific unit that is capable of splitting a dot into a plurality of divisions. The arrangement of splitting an ejected ink droplet into a plurality of parts to create a split dot having a plurality of divisions at a plurality of different positions in one pixel advantageously decreases the quantity of ink per position. This reduces penetration of ink in the direction of the depth of printing paper. Under the condition of a fixed quantity of ink, the split dot has a greater total area than the area of a single dot and ensure a higher resulting expressed density. This arrangement ensures multi-tone expression without changing the total quantity of ink ejected in each pixel.  <IMAGE>

Abstract: Context-aware systems and methods, location-aware systems and methods, context-aware vehicles and methods of operating the same, and location-aware vehicles and methods of operating the same are described. In various embodiments, a context or location service module, implemented in software, determines a vehicle context or a vehicle location based upon information that it receives from various context providers or location providers respectively. Software executing on a vehicle's computer can then cause one or more applications that are associated with a vehicle computer to be modified in a manner that changes their behavior. The behavior modification is based on the current context or location of the vehicle and thus provides a context-specific or location-specific user experience. The context or location can be ascertained through the use of one or more hierarchical tree structures that comprises individual nodes. Each node is associated with a context or location. The nodes are traversable by the vehicle's software to ascertain a more complete context or location.

Abstract: A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and fully-individualized (or “owner exclusive”). The client also includes and/or receives components which permit the access and protection of the encrypted content, as well as components that allow content to be provided to the client in a form that is individualized for the client. In some cases, access to the content will be governed by a rights construct defined in the license bound to the content. The client components include an object which accesses encrypted content, an object that parses the license and enforces the rights in the license, an object which obtains protection software and data that is individualized for the client and/or the persona operating the client, and a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona. Content is generally protected by encrypting it with a key and then sealing the key into the content in a way that binds it to the meta-data associated with the content. In some instances, the key may also be encrypted in such a way as to be accessible only by the use of individualized protection software installed on the client, thereby binding use of the content to a particular client or set of clients.

Abstract: A method of authorizing a key or lock device comprises the following steps: a first user device and a first system device used in a first level of a lock system, such as at a manufacturer, are created. A first encryption key is stored in the first user device and the first system device. When the user device is to be shipped to a second level of the lock system, such as a locksmith, an authentication process is carried out between the first user device and the first system device using the first encryption key stored therein. In case the authentication process was successful, a software operation is carried out by the first system device, by which the first encryption key stored in the first user device is replaced by a second encryption key. This second encryption key is stored in second system and user devices used in the second level of the lock system, thereby making the first user device operable with the second system and user devices. This prevents unauthorized use of keys and locks.
