    摘要: High-frequency ultrasound imaging can be performed with greater quality and suppressed grating lobes by using methods and systems for effectively reducing the temporal length of transmit grating lobe signals in received ultrasound echoes. Systems and methods are provided for improved high-frequency ultrasound imaging. In various aspects, the method of shortening the time domain of grating lobe signals comprises splitting an array of N transmit elements into K sub-apertures. In further aspects, the grating lobes are suppressed by performing signal processing of the shortened grating lobe signals. In certain aspects, the signal processing method comprises weighting the samples by a calculated phase coherence factor.

    摘要: Transitioning between an audio only circuit switched call and a video call. A client device, which is currently connected to one or more other client devices through an established audio only circuit switched call, receives input from a user to transition from the audio only circuit switched call to the video call. A video call invitation message is transmitted to the other client devices. The client device receives a video call accept message from the other client devices and begins transmitting video captured by its front facing camera to the other client devices. Responsive to receiving at least a video frame from each of the one or more other client devices, the client device transitions from the audio only circuit switched call to the video call. After transitioning to the video call, the circuit switched call is dropped.

    摘要: An integrated dynamically programmable gate array comprises a two dimensional array of programmable gates. These gates can be implemented as look up tables but hardwired gates with programmable interconnections are also possible. Each one of the gates receives plural input logic signals from plural other gates. Consequently, a broad range of logic combinations are possible. The gates further include locally stored multiple contexts dictating different combinatorial logic operations performed by the gates. The contexts increase the logic operations performable by the gate and the fact that the contexts are locally stored enables better integration and speed. Only a context instruction needs to be distributed among programmable gates. A context signal generator is included that generates a context signal indicating a change in an active one of the contexts. This active context dictates the logic operations of the gates that commonly receive by the signal. Since the contexts information is stored on the gate array, and specifically locally, the context signal can change as fast as every clock cycle of the programmable gate array. To increase functionality, context memory arrays, which store context programming information, are separately addressable so that a new truth table is storable in a first one of the context memory arrays while a truth table of a second one of the context memory arrays is dictating the logic operations performed by the gates. As a result, the functionality of each programmable gate can be increased by increasing the number of available functions for that programmable gate.
