  • Patent number: 7231936
    Abstract: A hot/cold water tube connection structure for plastic faucets comprises a hot/cold water connector tube made up of a valve seat and a coupling tube wherein the valve seat has a screw tube extending downwards at the bottom of a stop ring, and a sealing ring mounted at an appropriate position of the screw tube thereon to form engaging rings at both sides thereof. The coupling tube has an oblique face indented at one end edge against which a water-sealing hoop mounted at a screw joint of a water inlet tube is securely abutted, and a coupling joint with an internal screw thread section disposed at the inner wall of the other end thereof. Therefore, the connector tube assembled can avoid the problem of gaps found in the conventional tube connection structure, and facilitate an easer replacement thereof due to its separate type of design for economical and eco-protection purposes.

  • Patent number: 6954445
    Abstract: A method for improving the transmission efficiency of a short data burst (SDB) in a CDMA telecommunications network by generating an SDB comprising a service reference identifier, a service option omit field indicating whether a service option identifier is to be included or omitted from the SDB, and a data block. The SDB may thus be generated without a service option identifier and, as such, be more efficiently transmitted between a base station and a mobile station, thereby resulting in a typical gain over the prior art of up to 2% of data capacity.

  • Patent number: RE39878
    Abstract: Disclosed is an apparatus for initiating an over the air parameter administration (OTAPA) of a mobile station without the need for interacting with a mobile station user. A unique service option number included with the initial page indicates to the mobile station that an update is being requested. The mobile station performs a network validation check (SPASM) before permitting the update to take place. Flags are used in the network to alert the system that an attempted update was not completed because a mobile station was not update accessible for any of several reasons. The flags cause the system to update when the mobile station next becomes update accessible. The questions raised in reexamination request No. 90/006,577, filed Mar. 25, 2003, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e).
