  • Patent number: 8136401
    Abstract: The invention relates to a micromachined accelerometer using a movable seismic mass suspended in relation to the substrate by elastic connections only allowing translation in its own plane along a sensitive axis (Oy). The mass acts on at least one elongate resonator by means of a force amplification structure associated with this resonator. The amplification structure comprises a rigid lever arm, a first end of which is connected to the seismic mass by a connection having, in the plane of the mass, a high stiffness in the direction of the sensitive axis (Oy) and a low stiffness in the perpendicular direction, and a second end is connected to an anchor point on the substrate. The second end of the lever arm is a rigid head piece surrounding the anchor point and connected to this anchor point by a rotational connection about a center of rotation.

  • Patent number: 8140001
    Abstract: Techniques for detecting wireless devices that are signaling in high proximity to a convoy or other operation and preventing messages from reaching the wireless devices. One class of the techniques uses surgical jamming methodologies that minimize power consumption and collateral interference, while being maximally inconspicuous; another class uses baiting beacons to prevent the messages from reaching the wireless devices. Still another class of techniques denies wireless devices access to a wireless network. An exemplary embodiment applies the techniques to wireless devices and beacons in a GSM network.

  • Patent number: 8136369
    Abstract: A hybrid system which utilizes high purity oxygen from a local pipeline, which is blended with low purity oxygen from an on-site or local cryogenic distillation system, thus resulting in a blend of intermediate quality which satisfies the needs of the customer. In order to offset the operating and energy costs associated with this fairly low profit margin intermediate purity oxygen, high purity nitrogen at high pressure is simultaneously exported to the local pipeline, thereby acting as a credit to the overall system.

  • Patent number: 8139598
    Abstract: A UE is described herein that has a defined QoS database which is used to organize and store various QoS parameter sets which are used to help establish media flows. In one embodiment, the QoS database includes a plurality of tables, where each table is associated with a particular application, and where each table has a plurality of rows, and where each row includes a media type, a requested QoS parameter set, and an optional minimum QoS parameter set. An operator can use a communication network to populate/provision the QoS database. An operator can also use the communication network to fine-tune (update) the QoS database which enables them to enhance the bearer QoS for existing applications and to enable the appropriate bearer QoS for future applications.

  • Patent number: 8139530
    Abstract: A system and method for using Mobility Management (MM) and Session Management (SM) procedures in an SAE/LTE system. The present invention modifies several MM and SM procedures that have been defined for other 3GPP access systems (such as GERAN, UTRAN) so that they meet the requirements of LTE/SAE. While the present invention re-uses some existing procedures, it further defines new protocols for MM and SM procedures when accessing 3GPP systems by Evolved UTRAN (EUTRAN). With respect to the new protocols, the encoding rules are re-used from the existing MM and SM procedures and a very similar general message format is created. With respect to the signaling messages, the present invention re-uses the existing information element definitions for each parameter included in a message.

  • Patent number: 8140105
    Abstract: The present invention presents a method for controlling output power and reducing interference in a radio communications network wherein data transmitted over a radio interface is coded and transmitted in radio blocks. The data passes a buffer of a node before transmission. The method is characterized by a step of determining a recommended Modulation and Coding Scheme level, MCS level, based on at least one radio quality measurement. A further characterizing step is analyzing of buffer characteristics and/or radio block usage of transmission radio blocks to determine if there is a preferred MCS level compared to the recommended MCS level. The preferred MCS level is typically a more robust MCS level. The recommended MCS, level if so determined, is decreased to the preferred MCS level, and in relation to decreasing the MCS level decreasing the output power according to a predefined down regulation scheme. The interference level is reduced in the network depending on an application type.

  • Patent number: 8140033
    Abstract: The invention relates to a method for automatically matching the antenna impedance for a radiofrequency transmission circuit having an amplifier. An impedance matching network is inserted between the amplifier and the antenna. The output current i and voltage V from the amplifier and their phase shift are measured, and from this the complex impedance, defined by V/i, is deduced. The antenna impedance is calculated as a function of this complex impedance and as a function of the known present values of the adjustable impedances of the matching network. New values are calculated, from the calculated value of the antenna impedance, for the adjustable impedances of the matching network that allow an overall load impedance of the amplifier to be obtained which is as close as possible to the nominal load impedance Zopt of the amplifier, and the matching network is controlled to adjust the adjustable impedances to these new values.
