Abstract: The present disclosure relates to systems and methods for determining an engagement profile of a participant by associating electronic activities to a profile. It may generate the engagement profile based on analysis of the electronic activity level. An example implementation may contain the following steps. The system may access for a first record object a plurality of electronic activities linked with the first record object. The system may identify for a participant from the plurality of electronic activities a set of electronic activities including the participant. The system may determine an engagement profile of the participant based on a first number of electronic activities of the set of electronic activities sent by the participant, a second number of the set of electronic activities received by the participant and a temporal distribution of the set of electronic activities. The system may store the engagement profile in one or more data structures.

Abstract: A dual differential sawtooth signal generator includes a first sawtooth voltage generator that has a first capacitor and a second capacitor that are alternately charged with a feedback control source current from a low voltage reference voltage level. A second sawtooth voltage generator has a first discharge capacitor and a second discharge capacitor that are alternately discharged with a feedback control sink current from a high voltage reference voltage level. The output signals of the two sawtooth voltage generators are compared to control a phase frequency comparator that provides signals to control a dual charge pump that provides the feedback control source current and that provides the feedback control sink current.

Abstract: A sawtooth voltage generator has a first capacitor that is charged with a variable feedback control current to provide a sawtooth output signal with a controlled amplitude. A feedback loop includes a comparator that compares a version of the sawtooth output signal with a fixed voltage reference to provide a comparator output signal to a phase frequency comparator, the output of which controls a source of the variable feedback control current. A method includes controlling the amplitude of a sawtooth output signal by charging a capacitor in a sawtooth voltage generator with a variable feedback control current; comparing a version of the sawtooth output signal with a fixed reference voltage to provide a comparator output signal; processing the comparator output signal in a phase frequency comparator to provide up/down control signals; and controlling the variable feedback control current with the up/down control signals from the phase frequency comparator.
