Abstract: An ultrasonic includes: a piezoelectric layer; an absorbing layer disposed at a lower portion of the piezoelectric layer, configured to absorb an acoustic signal; and a connection part disposed between the piezoelectric layer and the absorbing layer. The connection part may deform at least partially so that a plurality of acoustic signals radiated from the piezoelectric layer due to the connection part have different magnitudes. In the case of the ultrasonic probe, since the magnitude of the acoustic energy radiated from the center of the ultrasonic probe is larger than the magnitude of the acoustic energy radiated from the side of the ultrasonic probe, the directivity of the ultrasonic signal is improved and a side lobe is decreased. In addition, an apodization effect capable of suppressing overlapping between adjacent phases can be obtained by using a difference in the magnitude of the acoustic energy to be radiated.

Abstract: Applications on a computing device provide notifications associated with the application to a notification system. A notification includes an identification of content to be presented for the notification and an indication of when the content is to be presented. The notification system presents the notification content at the appropriate time regardless of whether the application is executing and without resuming execution of the application if the application is not running. Various power efficiency techniques are also used to determine which notifications are presented and when a user interface is updated to reflect those notifications in order to avoid updating the user interface to reflect notifications that would not be observable (e.g., due to a power mode of the computing device).
