  • Publication number: 20240210558
    Abstract: Provided is an ultrasound device including a controller and an ultrasound transceiver. The controller may classify a plurality of elements included in an ultrasound array into a plurality of sector elements, provide a transmission control signal for selecting one of the plurality of sector elements as a transmission sector, and provide a reception control signal for selecting one of the plurality of sector elements as a reception sector. The ultrasound transceiver may transmit a transmission ultrasound signal to an object by selecting the transmission sector from the plurality of sector elements included in the ultrasound array based on the transmission control signal, and receiving a reception ultrasound signal reflected from the object by selecting the reception sector from the plurality of sector elements based on the reception control signal.

  • Publication number: 20100115552
    Abstract: A method and apparatus is provided for receiving an Electronic Service Guide (ESG) by a mobile communication terminal in a Digital Video Broadcasting-Handheld (DVB-H) system including a service provider providing a broadcast service and the mobile communication terminal receiving the broadcast service from the service provider. Upon receipt of a broadcast service request, the mobile communication terminal determines whether a first ESG about the broadcast service has been stored. When the first ESG has been stored, the mobile communication terminal requests the service provider to first transmit broadcast data among a second ESG and the broadcast data contained in the broadcast service, based on the first ESG. The mobile communication terminal receives the broadcast data first from the service provider and displays the received broadcast data.
