Abstract: A characterization circuit for an optical device includes: an optical device, a switch, a switch driver, one or more resistors, and one or more capacitors. The switch driver is configured to receive a trigger pulse from an external pulse generator and to provide the trigger pulse to the switch, which causes the switch to be in an on state. The one or more capacitors are configured to, when the switch is in an off state, receive a charge current (e.g., with a greater than 50 nanoseconds rise time) from an external driver voltage source via the one or more resistors; and, when the switch is in the on state, discharge a current pulse (e.g., with a less than 10 nanosecond pulse width) to the optical device. The optical device is configured to receive the current pulse and to emit, based on the current pulse, an optical output pulse.

Abstract: The present disclosure discloses a method and system for dynamically processing financial transactions. The method includes receiving a transaction request including at least one unique identifier field to transfer payment into an account associated with a payment instrument and authorizing the transaction request based on one or more predetermined rules. The payment instrument is used at an electronic device by a merchant for transfer of the payment from a merchant account. Thereafter, the method includes generating a direct fund transfer message based on the at least one unique identifier field upon authorization of the transaction request and transmitting the direct fund transfer message to an issuer associated with the merchant account for authentication of the direct fund transfer message. Lastly, the method includes transferring dynamically the payment from the merchant account to the account associated with the payment instrument when the direct fund transfer message is authenticated by the issuer.

Abstract: Systems and methods are described for managing saved web pages on a user device. In an example, when a user bookmarks a web page at the user device, the user device can send the bookmark to a server. A service on the server can gather information about web page and associate a plurality of tags with the web page based on that information. The service can compare the web page's tags to tags of other previously bookmarked web pages to identify a possible matching web page. The service can perform a semantic similarity analysis between the two web pages to determine whether their similarity exceeds a threshold. Where the similarity does exceed the threshold, the service can notify the user device. The user device can notify the user and present options for the new bookmarked web page.

Abstract: A system and method to manage handover between wireless audio devices (such as earbuds) of primary responsibility for communicating with a third device such as a phone or tablet. A first wireless audio output device manages communications between a third device and a second wireless audio output device. The wireless audio output devices determine the signal quality of the connection between them. If that signal quality drops below a threshold, the wireless audio output devices determine the rate of change of that signal quality. If that quality is dropping rapidly, the wireless audio output devices check to see which has the better connection to the third device. If the second wireless audio output device has a better connection to the third device than that of the first wireless audio output device, then the wireless audio output devices can trigger a handover from the first wireless audio output device to the second wireless audio output device.
