  • Patent number: 11706682
    Abstract: In general techniques are described by which to provide switchable communication transport for communication between primary devices and vehicle head units. A primary device comprising a memory and a processor may be configured to perform the techniques. The memory may store an operating system and an application. The processor may execute the operating system to present a single communication interface by which the application establishes a first transport between the primary device and a vehicle head unit that facilitates execution of a mode in which the application provides data for presentation by the vehicle head unit. The processor may also execute the application to transmit, during execution of the mode, the data via the first transport, where the operating system switches, during execution of the mode, from the first transport to a second transport. The application transmits, during execution of the mode, the data via the second transport.

  • Patent number: 11381950
    Abstract: An example method includes identifying, by a mobile computing device, short-range wireless communication signals that are associated with a vehicle computing system; determining, by the mobile computing device, based on the short-range wireless communication signals, that the mobile computing device is proximate to the vehicle computing system; identifying, by the mobile computing device, an electrical connection between the mobile computing device and the vehicle, wherein the electrical connection is provided by an electrical cable that connects a port of the mobile computing device to a port of the vehicle; determining, by the mobile computing device, that the electrical connection is a charge-only connection, wherein the charge-only connection enables an electrical charging or discharging of the mobile computing device but prohibits any data transfer between the mobile computing device and the vehicle computing system; and outputting, by the mobile computing device, a notification indicative of the charge-

  • Patent number: 8399360
    Abstract: A method is provided for cleaning a semiconductor topography having one or more contact openings etched through a dielectric layer formed on a substrate. The method substantially eliminates unfilled contacts and reduces contact defects. Generally, the method involves: (i) heating the substrate in a processing chamber to a predetermined temperature; (ii) generating a plasma upstream of the process chamber using a microwave generator and a process gas comprising nitrogen and hydrogen or argon and helium; and (iii) introducing the plasma into the process chamber to clean the semiconductor topography. As the clean is accomplished substantially without the use of an organic solvent, galvanic corrosion of contacts subsequently formed in the contact openings is substantially eliminated. Other embodiments are also described.

  • Patent number: 7901976
    Abstract: A method is provided for forming a borderless contact to a local interconnect (LI) line on a substrate. Generally, the method includes steps of (i) depositing a nitride layer over a number of LI lines on the substrate, to substantially cover the LI lines; (ii) etching the nitride layer to form spacers adjacent to sidewalls of at least one of the number of LI lines and to expose at least a portion of a top surface of the LI line; (iii) depositing an inter-layer dielectric, such as an oxide, over the number of LI lines on the substrate and the spacers formed adjacent thereto; and (iv) performing a contact etch to etch contact openings through the inter-layer dielectric to expose the portion of the top surface of the underlying LI line. Other embodiments are also disclosed.

  • Publication number: 20060037063
    Abstract: A system for controlling network access to products. The system includes a security appliance connected to a product under operational control of a first entity, a product connection platform and a user terminal under operational control of a second entity, the product connection platform being accessed by the user terminal, and a trust relationship established between the first entity and the second entity based on predetermined criteria between the first entity and the second entity, the trust relationship being represented by a certificate or public/private key exchange. Authentication of access by a user of the user terminal of the second entity to the product of the first entity is deferred to the product connection platform of the second entity based on the predetermined criteria of the trust relationship, whereupon if authentication is granted, the user is provided access to the product.
