  • Patent number: 8390387
    Abstract: A crystalline semiconductor resonator device comprises two matched resonators which are aligned differently with respect to the crystal structure of the crystalline semiconductor. The resonators each comprise a portion of a material having a different temperature dependency of the Young's modulus to the temperature dependency of the Young's modulus of the crystalline semiconductor material. In this way, the suspension springs for the resonators have different properties, which influence the resonant frequency. The resonant frequency ratios between the first and second resonators at a calibration temperature and an operation temperature are measured. A frequency of one (or both) of the resonators at the operation temperature can then be derived which takes into account the temperature dependency of the one of the resonators.

  • Patent number: 8391261
    Abstract: The invention, which relates to a method for the generation of beacons by a base station in a wireless communications network, consisting of at least one base station and at least one station, the beacons being generated repeatedly at time intervals, is based on the object of specifying a method with which the generation of the beacons can be tailored to needs, achieving a reduction of the energy demand and the emissions, and an improvement in the security. According to the invention, the object is achieved in that the generation of the beacons is started with a switching on of the base station and is ended after the expiry of a wait time tw0 in the event that no station is connected to the base station, and in that the generation of the beacons is started by a receipt of a probe request from a station of the communications network and is ended after the expiry of a wait time tw1 in the event that no station is connected to the base station.

  • Patent number: 8391837
    Abstract: A Trusted Service Manager (TSM) receives via a first communication channel from a Service Provider (SP) a request (REQ(MIA)) that contains an application (MIA) together with a unique identifier of a mobile phone (MOB), particularly its telephone number. The mobile phone (MOB) is equipped with a memory device (MIF) that comprises multiple memory sectors being protected by sector keys. Preferably the memory device (MIF) is a MIFARE device. The TSM extracts the application (MIA) and the unique identifier from the received request, assigns destination sector(s) and associated sector key(s) of the memory device (MIF), compiles the application (MIA), the sector key(s) and the sector number(s) of the destination sector(s) into a setup-message (SU(MIA)), encrypts the setup-message and transmits it to either the mobile phone via a second communication channel or the Service Provider via the first communication channel (CN).

  • Patent number: 8390331
    Abstract: Various exemplary embodiments relate to improved fabrication of CMOS transistor arrays for integrated circuits. Increased regularity in standard-cells using gate-isolation architecture may permit further reduction in feature size. MOSFETs may be spaced at roughly equal pitch and have increased channel lengths for leakage current reduction. Logic gates may be designed to have nominal channel lengths for speed and increased channel lengths for leakage current reduction. Further leakage current reduction may involve specialized channel lengths for isolation MOSFETs. Thus, the combination of the gate-isolation technique with MOSFETs having lengthened channels that are evenly spaced at substantially the same pitch may produce a flexible library architecture for improved standard-cell designs in advanced CMOS technology nodes.

  • Patent number: 8389392
    Abstract: The present invention relates to a FinFET with separate gates and to a method for fabricating the same. A dielectric gate-separation layer between first and second gate electrodes has an extension in a direction pointing from a first to a second gate layer that is smaller than a lateral extension of the fin between its opposite lateral faces. This structure corresponds with a processing method that starts from a covered basic FinFET structure with a continuous first gate layer, and proceeds to remove parts of the first gate layer and of a first gate-isolation layer through a contact opening to the gate layer. Subsequently, a replacement gate-isolation layer that at the same time forms the gate separation layer fabricated, followed by filling the tunnel with a replacement gate layer and a metal filling.
