Abstract: This application relates to methods and apparatus for driving a transducer with switching drivers. A switching driver has first and second supply node for receiving supply voltages and includes an output bridge stage, a capacitor and a network of switches. The network of switches is operable in different switch states to provide different switching voltages to the output bridge stage. A controller is configured to control the switch state of the network of switches and a duty cycle of output switches of the output bridge stage based on an input signal to generate an output signal for driving the transducer.

Abstract: This application relates to methods and apparatus for driving a transducer with switching drivers. A driver circuit has first and second switching drivers for driving the transducer in a bridge-tied-load configuration, each of the switching drivers having a respective output stage for controllably switching the respective driver output node between high and low switching voltages with a controlled duty cycle. Each of switching drivers is operable in a plurality of different driver modes, wherein the switching voltages are different in said different driver modes. A controller controls the driver mode of operation and the duty cycle of the switching drivers based on the input signal. The controller is configured to control the duty cycles of the first and second switching drivers within defined minimum and maximum limits of duty cycles; and to transition between driver modes of operation when the duty cycle of one of the switching drivers reaches a duty cycle limit.

Abstract: A medical device for assessing a health status of a patient is described. The medical device receives a selection of two or more health scores, and obtains physiological parameter measurements from one or more sensor modules based on the selection of the two or more health scores. The medical device generates the two or more health scores using the physiological parameter measurements received from the one or more sensor modules. The two or more health scores are generated based on a workflow for assessing the patient. The medical device displays the two or more health scores on a display screen.

Abstract: A computer-implemented method for processing an application for a mortgage loan, such that the mortgage loan is configured to include a set of financial lending requirements and further include certain financial lending risks associated with financing the mortgage loan. The steps of the method include receiving the mortgage loan application, processing the mortgage loan application through an electronic database, applying the set of financial lending requirements to the mortgage loan application, generating a listing of at least one eligible lender or loan product based on the application of the financial lending requirements to the mortgage loan application, and submitting the mortgage loan application to the eligible lender, the mortgage loan being configured such that the financial lending risks are configured to be absorbed by a secondary mortgage market investor.
