Abstract: Network nodes and interfaces are identified in a combined CDMA/eHRPD and LTE network. Messages captured by a monitoring system on different interfaces are combined in session records. The session records associated with the same network nodes correlated using parameters in the session records. Session records on an A11, A10 and S2a interfaces are correlated using a home network prefix and interface identifier data or home address information.

Abstract: An ink jet printer includes an image transfer drum and a print head for ejecting drops of ink toward the image transfer drum as the drum rotates relative to the print head undergo. A control mechanism controls operation of the print head relative to rotation of the drum in response to a dot clock signal. The control mechanism includes a position encoder which generates an encoder signal at a frequency dependent on rotation of the image transfer drum and a digital phase locked loop circuit which receives the encoder signal and generates the dot clock signal at a frequency equal to the frequency of the encoder signal multiplied by a rational number.

Abstract: A print head positioner includes a tilt mechanism that selectively engages and moves a carriage supporting the print head when the print head and supporting carriage are in a home position. The print head positioner is uncoupled from the carriage X-axis drive mechanism during imaging to avoid extraneous loading on the mechanism. The positioner includes interlocks to prevent inadvertent disengagement from the carriage during tilting and to restrict print head tilting when the carriage is away from the home position.

Abstract: An improved shift register uses fewer than 2*N latches, where N is the capacity in bits of the shift register and also the propagation delay from the input to the output of the shift register in terms of the system clock. An m-phase set of clocks are used, where m is an even number larger than two and and the duration of each clock phase is one half of the period of the system clock. The latches are arranged in m/2 strings of length 2N/(m-1), instead of one long string. The strings of latches are offset with respect to each other by two phases in terms of their connection to the multiphase clock, with each successive latch in each string being enabled by the clock signal whose phase immediatedly precedes the phase of the clock signal used to enable the preceding latch in that string. A multiplexer at the output puts the data from the multiple strings of latches back into one serial output stream.

Abstract: An alkaline, cyanide, aqueous electroplating composition of copper, tin, and zinc includes a small amount of nickel to enhance the inclusion of tin in the copper-tin-zinc plate deposited from the soltion. The plate resists tarnishing by a corrosion test solution, and retains its bright silvery-colored appearance because the plate preferably includes at least about 10.9 atomic wt % tin. The plating method for enhanced tin alloys through nickel additions to the bath is also described.

Abstract: Measurement accuracy of an oscilloscope is extended by monitoring the temperature within the oscilloscope, and automatically entering a calibration cycle if the temperature varies by a predetermined amount. A temperature sensor is strategically located within the oscilloscope to sense variations in temperature. A first sensed temperature value is stored. Upper and lower temperature limits representing the maximum permissible deviation from the stored value are calculated. Instantaneous temperature values from the sensor are compared with the stored value, and as long as the instaneous values are with the limits, an indication of extended accuracy is provided. If the instantaneous temperature values vary outside the limits, an automatic calibration cycle is initiated. After calibration, a new temperature value is stored and the monitoring process continues to ensure extended accuracy.
