A portable electronic device includes a housing, a processor unit received in the housing, and an anemometer unit mounted on the housing and electrically connected to the processor unit. The anemometer unit transforms pressure of wind blowing thereon into electronic signals, and the processor unit receives and processes the electronic signals to obtain wind pressures and velocities.

An arrangement analyzes a plurality of call detail records and determines that a particular call processing code has occurred a predetermined number of times during a previously defined time interval. The fact of these multiple occurrences of these processing codes is determined to be an indication of a trunk failure. A maintenance request is issued to address the detected failure.

An inspecting apparatus (20, 40, 50, 60) for liquid crystal displays includes a base plate (21, 41), a connecting device (200, 400) mounted on the base plate, a working table (25, 45, 55, 65) supported on the connecting device, and an electrical holding device (29) fixed to the working table. The electrical holding device can hold a mains switch (33) and an electrical connector (31) that is used to connect with leads of the LCD. Because the inspecting apparatus includes the electrical holding device for holding the electrical connector, operators can connect leads of the LCD and the electrical connector easily using a single hand. After that, operators can conveniently turn on the mains switch because the mains switch is adjacent to the electrical connector.

An assembling apparatus (20) for liquid crystal displays includes a base plate (21), a height adjustor (30) standing on the base plate, and a working table (25) supported on the height adjustor. The height adjustor can adjust the height of the working table relative to the base plate, so that the assembling apparatus can be conveniently used by operators with different statures.

The present invention relates to a new method for radiolabeling chemical compounds. The new method attains the goals of simplicity, high radiochemical yields, speed, versatility, and automation. An HPLC injection loop on an HPLC injection valve is loaded with a solution of precursor and the radiolabeling reagent is passed through the loop. The contents of the loop are then quantitatively injected onto the HPLC column for purification. Radiochemical yields are equal to or superior to conventional solution methods in all cases, even though no heat need be applied. Since no vials, transfer lines, cooling, heating, or sealing valves are required, no transfer losses occur, yields are high, and clean-up is minimal. This “loop method” is ideal for the preparation of radiolabeled compounds, in particular those prepared from [11C]-iodomethane.

"Transhybrid" loss is maximized in a transmission network of the active canceler type employed to couple receive and transmit unidirectional transmission paths to a bidirectional transmission path including 2-wire loaded type cable by controllably adjusting impedance elements of the canceler circuit in a prescribed sequence including adjustment of a network build out capacitor to obtain amplitude nulls of signals detected on the transmit path while supplying individual ones of a plurality of test signals to the receive path. The test signals include first and second signals having a plurality of equally spaced frequency components in first and second frequency bands, respectively, and a third signal having a predetermined single frequency. The adjustment sequence includes a plurality of iterative adjustments of predetermined impedance elements in predetermined groups until no changes in the impedance settings occur and multiple iterative adjustment of predetermined groups until no changes in the impedance settings occur. The impedance elements to be adjusted and the adjustment sequence are selected to rapidly converge the canceler circuit to an optimum transfer function for generating a correction signal which is substantially a replica of an error signal to be canceled from the transmit path.

A mobile phone anti-theft system includes a mobile phone, a SIM card and a real-name card-issuing system. The real-name card-issuing system includes a central processing unit, a first user information storage area, transmission equipment, and a card reader. The SIM card communicates with the central processing unit through the card reader and the transmission equipment. The real-name card-issuing system sends user information stored in the first user information storage area to the SIM card. If the SIM card needs to change the user information, it should verify first cryptographic keys with the real-name card-issuing system. The mobile phone includes a micro control unit, a second user information storage area and a transmission unit. The SIM card communicates with the micro control unit through the transmission unit. After each startup of the mobile phone, the mobile phone verifies second cryptographic keys with the SIM card.
