Abstract: Systems, methods, and non-transitory computer-readable media can provide at least one frame of a content item to a saliency prediction model, the saliency prediction model being trained to identify salient points of interest that appear in content items. Information describing at least a first salient point of interest that appears in the at least one frame can be obtained from the saliency prediction model. The first salient point of interest can be predicted to be of interest to users accessing the content item. A view-based projection can be applied to a region corresponding to the first salient point of interest, wherein the view-based projection enhances a quality in which the region is presented.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a first position corresponding to a user focal point prior to presenting a given frame of a content item. A landscape representation of the given frame is determined. The landscape representation describes the respective popularity of one or more regions in the frame as a topology. A second position corresponding to the user focal point is determined based at least in part on the landscape representation and the first position. The second position is predicted to be the position of the user focal point when presenting the given frame.

Abstract: Systems, methods, and non-transitory computer-readable media can obtain a spherical media content item that captures at least one scene from a plurality of different positions. A three-dimensional object with a plurality of faces that converge at a point is determined. At least a first portion of the spherical media content item is mapped to at least a first face in the plurality of faces.

Abstract: Systems, methods, and non-transitory computer-readable media can obtain a spherical media content item that captures at least one scene from a plurality of different positions. A three-dimensional shape having a plurality of faces is determined, each face being associated with a respective set of original boundaries. A respective set of expanded boundaries for one or more of the plurality of faces is determined. Respective portions of the spherical media content item are mapped to each of the one or more faces, wherein a first portion of the spherical media content item is mapped to a first face having a set of expanded boundaries.

Abstract: A multimedia bitrate adaption method for individual users wherein only a set of predetermined bitrates may be selected as the multimedia bitrate of the user. The predetermined bitrates are quantized into exponentially distributed levels, and the users' experiences corresponding to the predetermined bitrates are with the same intervals, thereby increasing the service capacity and improving user satisfaction.

Abstract: The stacked-substrate structure includes a first substrate having a first die embedded therein, a second substrate having a second die embedded therein, a plurality of soldering elements, and a third die. The soldering elements are disposed between the first and the second substrates and connected to the first and the second substrates. The first and the second substrates are electrically connected via the soldering elements. The first substrate, the second substrate, and the soldering elements define an accommodating space. The third die is arranged in the accommodating space and is connected to one surface of the first substrate. The third die is electrically connected to the first and the second dies via the first substrate. Thus, the thickness of the stacked-substrate structure can be reduced, and the first and the second dies of the stacked-substrate structure can be test separately in different platforms.

Abstract: A heat dissipation device has a main controller and a fan module having a motor coil, a connection interface, a PWM driving circuit and a fan monitor chip. The connection interface has a control pin, an error report pin, a power supply pin and a ground pin. The control pin receiving a control signal. The PWM driving circuit adjusts current magnitude and current direction of the motor coil to drive the fan module. The fan monitor chip is connected to the connection interface and the PWM driving circuit, receives the control signal, generates and sends PWM signals to the PWM driving circuit according to the control signal and sends an acknowledgement signal via the control pin after receiving the control signal. The main controller can check if the control signal is correctly received based on the acknowledge signal.

Abstract: An eyeglass frame and an assembling means thereof are disclosed. The assembling means of the eyeglass frame locks with a main body of the eyeglass frame. A connecting shaft with a plurality of locking teeth is arranged on the assembling means of the eyeglass frame and a wall of a receiving slot of an auxiliary eyeglass frame is also disposed with locking teeth so as to engage with and assemble with the connecting shaft of the assembling means of the eyeglass frame. Thereby the assembling way among the main body of the eyeglass frame, the auxiliary eyeglass frame, and the assembling means of the eyeglass frame is in a removable and detachable form. Moreover, mounting grooves for receiving removable lenses are set on the main body of the eyeglass frame and the auxiliary eyeglass frame respectively. Thus each component can be assembled and disassembled removably. Therefore, users can choose the components according to their needs to form eyeglass frames and production resources are used more efficiently.
