Abstract: A wireless fuel gauge assembly including a fuel tank containing fuel having a level defining a liquid-air boundary. A control determines a digital indication of the fuel level. The control is able to determine plural digital signals that provide incremental level readings. A transmitter then sends an RF signal indicative of the level. A receiver captures the RF signal and communicates to a fuel gauge.

Abstract: An improved key system incorporates a number of electrical components. In one main aspect, the key is provided with electrical communication to components on the vehicle when the key is inserted into the ignition. The key connects to an antenna associated with the vehicle, such that the combined antenna size is greater than would otherwise be possible. In this application, the antenna is utilized for garage door opener purposes, and a switch is mounted on the key for actuation of the garage door opener. In another aspect, the key is recharged when inserted into the ignition. Further, the key may be provided with various other functions such as memo, vehicle deactivation, two-way communication, and other security applications. In embodiments of the key, the switches are positioned relative to a thumb area such that inadvertent actuation of the switches is made less likely.

Abstract: A method of fitting content elements of a composition to a media layout is disclosed. Each content element has an associated content type, and the media layout has a content rendering space for presenting information contained in the content elements. For each content type, a content scale factor is initialized and extent values are computed. If the content elements do not fit within the media layout, then non-fit factors are determined, the scale factors and extent values are recomputed and these steps are repeated until the content fits. Another method computes a layout of a composition in a recursive fashion using a design tree. Design children components of a current component in the design tree are identified, and new media components between the current component and the identified design children components are created. A media division for each media component indicates a portion of the layout for each media component. Another method computes a layout of a composition for a chosen medium.

Abstract: A vehicle communication system includes a trainable transmitter that is connected with the antenna associated with the AM/FM radio receiver in the vehicle. The trainable transmitter preferably is capable of learning a variety of communication signals and then later, selectively transmitting them to communicate with a variety of external, remotely located devices. A system designed according to this invention allows a single antenna to be used for emitting signals and receiving signals and, moreover facilitates communication with a variety of remotely located devices such as a garage door opener and a home security system.

Abstract: A programmable transmitter includes a receiver for receiving a coded signal at a desired frequency. The code is stored in memory during a learning mode and is then retransmitted sequentially at a plurality of frequencies, including said desired frequency. During this time, the operator observes the device to be operated and indicates to the transmitter when the controlled device performs the desired function, i.e., when the desired frequency is transmitted. At that time, the operator presses a button on the transmitter, and the transmitter stores the most recently transmitted frequency.

Abstract: A passive remote garage door operator system including a magnetic field sensor which detects a magnet having a flux density and a transmitter that sends a coded security signal to activate a garage door. A controller determines whether the magnet field sensor detects the magnet from a first direction or a second direction and activates the position of the garage door. The magnetic field sensor is preferably affixed to the underside of a vehicle and the magnets are embedded in a driveway leading to the garage. The system thereby automatically opens a garage door based upon the approach of a vehicle and closes automatically based upon the exit of the vehicle without any intervention by the human vehicle operator.

Abstract: A display panel for displaying information to a vehicle operator is placed on a rear surface of a sunvisor for the vehicle. The display panel is hidden when the sunvisor is moved to a stowed position but is easily accessible to the operator when the sunvisor is moved to its extended position. The location of the display panel on the sunvisor allows the operator easy access to the information without diverting information from the road. In addition, control buttons are associated with the display panel such that the operator is able to adjust the information displayed on the panel, or to adjust a component for responding to the information displayed on the panel.

Abstract: One aspect of the present invention provides for a three-way separation of the information in a document. In a particular embodiment, the document is separated into its content, design and media aspects. In one embodiment, an information data structure is provided that includes three tree structures. A design tree structure represents the design of a composition and includes design components. A content tree structure represents the content of the composition and includes content elements. A media tree structure represents the selected medium of the composition and includes media components. The content and media tree structures are linked to the design tree structure. The design tree structure, the content tree structure and the media tree structure are unique but utilize at least some common components from one another. A component data structure represents a content element within a composition. The component includes a content facet, a design facet and a media facet.

Abstract: A three-way separation of information in a document includes content, design and media aspects. This division supports automatic rendering to multiple forms of media such as print, Intranet, Internet, and OLE embedding. A method adds content to a composition having a chosen design and automatically calculates a layout for the composition. A content object is dropped upon a receiving component of the composition. The dropped content object has at least one potential type. A potential type of the content object is matched with a compatible type of the receiving component. Next, the design tree is modified to incorporate the content object, and media layout values are calculated for each content element of the composition The dropped content may change the existing content, may replace it completely, may be inserted into the existing content, may change its properties, or may result in new components being created in the design tree.

Abstract: A three-way separation of information in a document includes content, design and media aspects. This division supports automatic rendering to multiple forms of media such as print, Intranet, Internet, and OLE embedding. A method changes the design of a composition having a current design that is rendered in a particular medium. The composition is represented by components in a current design tree and includes content elements associated with the components. A new design tree is created for the composition based upon a new design and new design components. Next, each of the content elements are linked into an association with one of the new design components such that the set of relationships between the content elements in the context of the new design are maintained. Media layout values are calculated for each content element of the composition. The content elements are laid out in the new design and the new design retains the composition rendered in the particular medium.
