  • Patent number: 8401553
    Abstract: A method and radio network controller (RNC) in a radio access network (RAN) for controlling access to a cellular telecommunication system. Upon receiving an access request from a given user equipment (UE) through a given radio base station (RBS), the RNC retrieves authorization information from an access control database within the RAN. The authorization information indicates whether the given UE is authorized to access the system through the given RBS. The RNC alternatively grants access or denies access to the UE based on the retrieved authorization information. The RBS is particularly useful for controlling access through small cells with limited capacity.

  • Patent number: 7298134
    Abstract: An example embodiment of an electrical-energy meter comprises a transformer for producing an electrical output proportional to an electrical current in a conductor of electrical energy, a circuit board electrically coupled to the transformer for facilitating the calculation and displaying of a cumulative amount of electrical energy passing through the conductor of electrical energy, a first optical transmitter, a second optical transmitter, and an optical receiver. The first and second optical transmitters and the optical receiver are coupled to the circuit board. The first optical transmitter and the receiver facilitate optical communications between the electrical-energy meter and a first type of external device. The second optical transmitter and the receiver facilitate optical communications between the electrical-energy meter and a second type of external device.

  • Patent number: 7084783
    Abstract: An electronic meter that is capable of handling an analog cellular phone or radio modem under the meter cover provides significant improvements in the thermal management and power handling that is associated with a circuit switched wireless device. The electronic meter comprises a power supply capable of delivering the transmitter power plus the associated losses due to transmitter efficiency. It is desirable to deliver the high power over a wide range of AC input voltages (typically from about 90 to 530 VAC). The meter packaging allows the power supply and the analog cellular modem to operate in an enclosed metering package without exceeding the operating temperatures of the electronic components. The packaging adapts to increased steady state (idle) conditions as well as increased transmit conditions.

  • Publication number: 20040232593
    Abstract: A preferred process comprises providing a pre-formed, substantially transparent window for a cover of an electrical-energy meter, and molding the cover from a molten resin that, when solidified, is substantially opaque. Molding the cover from a molten resin comprises causing a portion of the molten resin to contact a periphery of the window and allowing the portion of the molten resin to cool and thereby solidify so that the portion of the molten resin, upon solidifying, is molded over the periphery of the window and thereby seals and secures the window to the cover.

  • Patent number: 6659752
    Abstract: A mold assembly accepts a flexible inserted decoration sheet and molds a cylindrical component to include the inserted decoration sheet. The mold assembly has a female part a male part insertable thereinto such that the component is molded therebetween from an introduced mold material. The female part includes a circular wall, a cylindrical wall, and a pair of demarcating ridges on the cylindrical wall. The pair of ridges accept the inserted decoration therebetween and hold the inserted decoration against the cylindrical wall such that the introduced mold material stays substantially on a side of the inserted decoration opposite the cylindrical wall of the female part.

  • Patent number: 5520554
    Abstract: A device for electromagnetically shielding a cable or the like that is connected to a board connector on a circuit board inserted into a magazine using a corresponding cable connector. The circuit board includes a board front having an opening through which the cable connector is connected to the board connector. The device includes a shielding sleeve that is mounted on the circuit board over the board connector and extends through the opening in the board front. A shielding spring is mounted on the shielding sleeve between the sleeve and the opening in the board front. The sleeve is open towards the circuit board and the board front opening and is provided with recesses. The shielding spring includes a frame that extends around the sleeve and includes a plurality of outwardly directed, resilient tongues that lie against the board front. A plurality of resilient tabs lie along the shielding sleeve, the outermost parts of which include inwardly directed tongues.
