  • Patent number: 11432239
    Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

  • Patent number: 11355332
    Abstract: The use of a capacitor (22) to serve as the principal impedance in a negative feed-back loop in a voltage amplifier component (21) of a trans-impedance amplifier and actively controlling the amount of charge accumulated within the capacitor appropriately to improve the responsiveness and/or dynamic range of the amplifier. A switch (25) is electrically coupled to the inverting input terminal of the voltage amplifier and electrically isolated from the output terminal (23) of the voltage amplifier. The output voltage of the amplifier is proportional to the accumulation of charge, and the switch is operable to ‘reset’ the charge/voltage on the feedback capacitor, as desired. This arrangement decouples the structure of the switch from the output port of the voltage amplifier, and so avoids leakage currents and/or interfering voltage signals emanating from the switch structure and being felt at the output port of the voltage amplifier.

  • Patent number: 9784601
    Abstract: A system is described for time synchronizing digitized measurement signals, such as vibration signals. The digitized signals, which are acquired asynchronously by multiple distributed measurement units, indicate the operational condition of a machine or a process. To measure the phase of the digitized signals relative to a pulse tachometer input, the time between the leading edge of the tachometer pulse and the digitized samples is measured. To achieve phase-coherent synchronization across the distributed measurement units, a local synchronization signal is embedded into the data produced by the measurement units. The systems uses the synchronization signal to align the data in post processing, which phase aligns the data and aligns the data in absolute time. The synchronization signal may be encoded with a timestamp to provide additional timing information.

  • Patent number: 9425778
    Abstract: A continuously adaptive timing calibration function for a data interface is disclosed. A first calibration method is performed for a mission data path, typically at power-on, to establish an optimal sample point. Reference data paths are established for a second calibration method that does not disturb normal system operation. Data bit edge transitions are examined at fringe timing points on either side of the optimal sample point. Assuming that a timing change for the edge transitions indicates a drift of the optimal sample point, when a drift amount is determined to be greater than a correction threshold value the optimal sampling point for the mission path is adjusted accordingly. At no point does the continuous calibration function determine that any data bit is invalid since the optimal sampling point is always maintained. Also, at no point does continuous calibration require successive alternating data bit values such as 1-0-1 or 0-1-0.

  • Patent number: 8935127
    Abstract: A method for recording pulse signals which allows the reconstruction of a time reference. The time of every pulse signal event can be determined by counting sampling result bits preceding the respective sampling result bit using the known sampling frequency. For this purpose, every period of the sampling frequency is associated with a bit representing the respective sampling result and the sampling result bits are stored one by one and per channel in data blocks. The sampling frequency is preferably higher than a pixel clock, a sampling result bit associated with a flank of the pixel clock being marked. The pixel clock can thus be synchronized with the individual events exactly per sampling period. The invention further relates to the field of fluorescence correlation spectroscopy using confocal microscopes or laser scanning microscopes.

  • Patent number: 8924766
    Abstract: A method of performing and correcting a timing analysis performed by a data processing apparatus on a circuit formed of a plurality of cells to account for the reverse Miller effect. The timing analysis steps includes identifying cells on and in parallel with a signal path that are driven by a same signal and determining an output transition time and a delay using the characterization data for the cell. The correcting steps includes providing further characterization data for some of the cells; correcting the output transition time for some of the cells by increasing the output transition time by an amount dependent upon the Miller capacitance for the cell and using the correction to the output transition time to correct an input transition time for a next cell; and calculating a time taken for a data signal to travel along the signal path from the delay times.

  • Patent number: 8903670
    Abstract: In a receiver of electromagnetic or other waves, scaling of received frequencies in proportion to the respective source distances, so as to reveal the source distances and permit isolation of signals from a particular source by simple spectral filtering. Phase differences between transmitted frequencies due to the common source path lead to chirp eigenfunctions registering in the receiver as scaled frequencies. The chirps are extracted by implementing exponentially varying path delays in autocorrelators and diffractive spectrometers say using a medium with variable refractive index. Analogous exponentially varying phase shifts are applied to successive samples in the kernel of discrete Fourier transform implementations. Advantage lies in enabling distance-dependent frequency scaling in autocorrelation spectroscopy, as well as in conventional diffractive or refractive spectrometers or digital signal processing with uniform sampling.

    Abstract: Adjusting processor performance based on processing profiles. The method may determine that a process has entered a processing state after an idle state. In response to entering the processing state the processing time of the processor may be monitored. In response to the processing time exceeding a first threshold of time, the performance of the processor may be increased from a first level to a second level. In response to the processing time exceeding a second threshold time, the performance of the processor may be decreased from the second level to a third level. In response to the processing time exceeding a third threshold time, the performance of the processor may be increased from the third level to a fourth level. In response to the processing time exceeding a fourth threshold time, the performance of the processor may be decreased from the fourth level to a fifth level.

  • Patent number: 8824532
    Abstract: A method of generating a noisy receive signal for testing the performance of a mobile wireless communication device is described. A signal generator unit generates a transmit signal that frequency hops among a set of carrier frequency channels in a cyclic pattern having a time duration T. A wireless channel emulator unit generates a receive signal by modifying the transmit signal and also generates an interference signal by modifying the receive signal. The wireless channel emulator unit delays the interference signal relative to the receive signal by an integer multiple of the time duration T. The receive signal and the interference signal are combined by a combiner unit to generate the noisy receive signal.

  • Patent number: 8779787
    Abstract: Apparatus and method for determining variation in a predetermined physical property of a circuit. The apparatus includes monitored circuitry for generating output pulses, and configured such that each output pulse has a pulse width which is indicative of the current value of the predetermined physical property. Circuitry is then configured to receive both the output pulses generated by the monitored circuitry and an oscillating timing reference signal. With reference to the oscillating timing reference signal, the counter circuitry produces for each output pulse an associated count value indicative of the pulse width of that output pulse. Circuitry then compares the associated count values for at least two output pulses, in order to produce a comparison result used to determine the variation in the predetermined physical property. This provides a flexible mechanism for monitoring variations in a physical property on the fly during use of a data processing circuit.
