Title: Rf-transceiver front-end with implicit direction control for time division multiple access communication using submicron technology
Inventor: AKBARI RAHIM
IPC: H04B1/48
Filed: 2009-01-30
Abstract: 2.1. A new design configuration of an RF-transceiver front end is proposed.   2.2. The Power Amplifier (PA) output stage of the transceiver comprises a cascode circuitry of N-type transistors with open-drain-configuration. The cascode-transistor is acting as a common-gate-transistor, whose gate is controlled to block the transmitting-(TX) path.   The Low Noise Amplifier (LNA) input stage uses a common-gate configuration of a p-channel MOS-transistor that is controlled by the voltage at the bulk terminal. Lifting the bulk potential of this PMOS-transistor above its source potential disables the receiving-(RX)-path.   2.3. This design allows low cost implementation for TDMA-RF-transceivers especially for Bluetooth-Solutions. The number of external components is reduced. No additional TX/RX  switch is required. The same port and the same matching elements for the antenna's bandwidth adaptation are used for both, the TX-path and the RX-path.

Title: Printing layers of ceramic ink in substantially exact registration by differential ink medium thermal expulsion
Inventor: HILL GEORGE ROLAND
IPC: B41M1/12
Filed: 2009-12-29
Abstract: A method of partially imaging a substrate, for example glass, with a print pattern comprising layers of ceramic ink in substantially exact registration. The method relies on a mask ink layer defining the print pattern and differential thermal expulsion of ceramic ink medium during a heat fusing process between the areas outside the print pattern and within the print pattern.  This results in pigment and glass frit forming a durable image material adhered to the substrate within the print pattern and non durable material outside the print pattern, enabling its removal outside the print pattern to leave the desired layers of ceramic ink within the print pattern in substantially exact registration.

Title: Method and apparatus for accommodating duplicate mac addresses
Inventor: BRAGG NIGEL
IPC: H04L12/24
Filed: 2010-04-21
Abstract: Each access node is associated with one or more IP subnets with a preferred de-fault subnet. Each subnet is instantiated as a unique virtual Ethernet broadcast domain. As client nodes register on the communication net-work, they will dynamically try to obtain an IP  address for use on the communication network.  As part of this process, the MAC address of the client node will be checked to ensure that it is not a duplicate of another MAC address associ-ated with another client node that has already been assigned an IP address from the default subnet. When duplicate MAC addresses are de-tected, the device with the duplicate MAC  ad-dress will be assigned an IP address from a dif-ferent subnet so that more than one client device with the same MAC address are not associated with the same subnet. In one embodiment, a DHCP server may implement the process of checking for duplicate MAC addresses. In an Ethernet context, different IP subnet prefixes may be mapped to different S-VID values so that the different subnets are implemented as differ-ent VLANs within the Ethernet network.

Filed: 2010-05-14
Abstract: An engine having improved combustion characteristics is provided. The engine includes a fuel injection system that is variable between two operational states. In the first operating state, the fuel injectors provide a fuel spray having first spray pattern characteristics. When the system detects that an operation characteristic exceeds a threshold, the fuel injectors are displaced into a second operating state. In the second operating state, the fuel injectors provide a spray pattern having first spray pattern characteristics. The combustion cycle may be characterized by timing the fuel injection so that the fuel is sprayed into the cylinder early in the compression stroke. Further still, the combustion cycle may be characterized by controlling the fuel pressure so that the fuel pressure is inversely related to the load on the engine.
