Abstract:
A semiconductor buffer circuit and buffering method for driving capacitive loads that enhances the current sinking and sourcing drive characteristics at times when the input signal is changing. Two transistors are used, a source follower and a current source pull-down, with an input signal applied to the control input of the source follower transistor. The complement of the input signal is capacitively coupled to the control input of the current source pull-down transistor. As a result, changes in the input voltage increase or decrease the conductivity of the current source pull-down transistor, thereby allowing the capacitive load to be charged and discharged more efficiently.

Abstract:
Implementations described herein relate to methods, systems, and computer-readable media to label incoming phone calls. A method to label an incoming phone call includes detecting the incoming phone call associated with a caller identifier (ID), determining a location associated with the call, and analyzing a call header of the call to determine one or more call characteristics. The method further includes determining, based on the location and the call characteristics, if the location is spoofed and determining, based on the caller ID and the call characteristics, if an access network associated with the call is spoofed. The method further includes applying a trained machine learning model to determine whether the call is a robocall. The method further includes assigning a label to the call that indicates whether the call is a spoofed call or is the robocall and sending the label to a callee device associated with the call.

Abstract:
In one implementation, a computer-implemented method includes: receiving, at a computer system, a multimedia message service (MMS) message for delivery to a client computing device; storing, by the computer system, the MMS message; generating, by the computer system, a traditional short message service (SMS) message including a notification that the MMS message is available for download from the computer system; transmitting, by the computer system, the SMS message to the client computing device; receiving, after transmitting the SMS message, a request from the client computing device to download the MMS message; and sending, by the computer system, the MMS message to the client computing device.
