  • Patent number: 9337795
    Abstract: A signal path may operate in one of a plurality of gain modes such that for each gain mode, the product of a digital gain and an analog signal gain of the signal path associated with the particular gain mode are approximately equal to a fixed path gain. During each of one or more calibration phases, a calibration system may measure analog signals at a plurality of nodes of the first path portion, calculate an actual analog gain associated with the gain mode based on the analog signals measured at the plurality of nodes, calculate an error between the fixed path gain and a mathematical product of the actual analog gain associated with the gain mode and the digital gain associated with the gain mode, and modify at least one of the digital gain and the analog gain associated with the gain mode in conformity with the error.

  • Publication number: 20160097964
    Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

  • Publication number: 20160065734
    Abstract: A dialing method for a calling party includes determining a plurality of phone number groups to be dialed in a simultaneous or sequential ringing mode, each of the groups including at least one phone number; and transmitting the plurality of phone number groups and a dialing flag to a calling server. The dialing flag including a simultaneous or sequential ringing flag indicating that the plurality of phone number groups are to be dialed in the simultaneous or sequential ringing mode. The calling party can freely custom multiple phone numbers expected to be rung simultaneously or sequentially and transmit them to a calling server, without registering in the calling server in advance. Thus, the trouble of the user registering the numbers in the calling server may be avoided and the calling server does not need to maintain a large-scale database for storing the multiple numbers at a large cost.

  • Publication number: 20160056467
    Abstract: An alkali-ion battery is provided with a transition metal cyanometallate (TMCM) sheet cathode and a non-alkaline metal anode. The fabrication method mixes TMCM powders, conductive additives, and a polytetrafluoroethylene binder with a solution containing water, forming a wet paste. The wet paste is formed into a free-standing sheet of cathode active material, which is laminated to a cathode current collector, forming a cathode electrode. The free-standing sheet of cathode active material has a thickness typically in the range of 100 microns to 2 millimeters. The cathode electrode is assembled with a non-alkaline metal anode electrode and an ion-permeable membrane interposed between the cathode electrode and anode electrode, forming an assembly. The assembly is dried at a temperature of greater than 100 degrees C. The dried assembly is then inserted into a container (case) and electrolyte is added. Thick anodes made from free-standing sheets of active material can be similarly formed.

  • Patent number: 9215245
    Abstract: Systems and methods for automatically analyzing and predicting behavior of binary executable programs are provided. A virtual machine receives a URL or content based feature corresponding to a binary executable program and the virtual machine analyzes the behavior of the binary executable program. The safety information of the binary executable program is determined based on the analysis report generated by the virtual machine and its impact on the virtual machine. A binary explorer selects a URL or content based feature corresponding to the binary executable program to be analyzed. A binary analyzer automatically records the behavior of the binary executable program to generate a report containing safety information describing the interaction occurred between the binary executable program and the analysis virtual machine. A result interpreter determines and predicts whether the binary executable program is safe based on the information generated by the binary analyzer.

  • Patent number: 9214948
    Abstract: A comparator tracking scheme for an analog-to-digital converter (ADC) may implement a dynamic window size by varying, over time, a number of comparators powered up to convert an analog input signal to a digital output signal. A comparator-tracking scheme may be implemented, for example, in a controller coupled to a plurality of comparators in an ADC. For example, the controller may determine a window size for the ADC and determine a window position for the ADC. The controller may then activate comparators of the ADC within a window centered at the window position and having a width of the window size. The controller may determine a window size by analyzing an output of a filter. When the filter output indicates a rapidly changing analog input signal, the controller may dynamically increase a window size of the ADC, which may increase a number of comparators powered on.
