Abstract: The present disclosure relates to the field of recruitment systems. The system comprises a memory, an input module, a talent reader, a repository, a talent pool creation module, and a pre-offer module. The candidates provide values corresponding to tags in a pre-defined resume format to generate a resume, read by the talent reader to extract the tag values and store in candidate repository. An assessment test for the candidate based on the pre-determined questionnaires and tag values is created, and responses of the test is assessed to generate a score for filtration of candidates. A recruiter sends a set of desired tag values which are extracted and mapped with the stored tag values to generate a mapped set of candidates for sending pre-offer letters. The system create a talent pool and reduces turnaround time of the selection process.

Abstract: Circuits and methods for driving ERM motors are disclosed herein. An embodiment of the circuit includes an input, wherein an input signal is receivable at the input and a back EMF signal. The circuit operates in a closed loop mode when the back EMF signal is less than a lower threshold value and the difference between the value of the input signal and the back EMF signal indicates that the velocity of the motor needs to increase. The circuit operates in an open loop mode when the back EMF signal is greater than a high threshold value and the difference between the value of the input signal and the back EMF signal indicates that the velocity of the motor needs to increase.

Abstract: An apparatus and method for controlling a haptic actuator. A haptic actuator controller can includes driver input amplifier, an actuator feedback amplifier, an actuator driver, and a gain controller. The actuator driver is configured to drive a haptic actuator based on a difference of output of the input amplifier and output of the actuator feedback amplifier. The gain controller is configured to determine a boost interval for initiating motion of the haptic actuator, the boost interval based on a boost threshold back-electromotive-force (BEMF) voltage value exceeding a BEMF voltage generated by the haptic actuator. The gain controller is also configured to apply boost gains in the input amplifier and the feedback amplifier during the boost interval. The boost gains are higher than gains applied subsequent to the boost interval to maintain motion of the haptic actuator.

Abstract: A method for driving a Linear Resonant Actuator (LRA) is provided. During a first off interval, the back-emf of the LRA is measured. During a first off interval, a timer is started when the back-emf reaches a predetermined threshold, and after a predetermined delay has lapsed following the back-emf reaching the predetermined threshold during the first off interval, the LRA is driven over a drive interval having a length and drive strength. A second off interval is entered following the drive interval, and during the second off interval, the back-emf of the LRA is measured. During the second off interval, the timer is stopped when the back-emf reaches the predetermined threshold. The value from the timer that corresponds to the duration between the back-emf reaching the predetermined threshold during the first off interval and the back-emf reaching the predetermined threshold during the second off interval determines the length.
