A fuel injection controller for an engine having a direct injector for injecting fuel into a cylinder and an intake injector for injecting fuel into an intake passage. When the engine is idling, the controller reduces a target engine speed while preventing the engine from stalling. The fuel injection controller supplies fuel to the engine through the direct injector and the intake injector when the engine is idling. The electronic control unit determines if there is a possibility of the engine stalling when the engine is idling. When having determined that there is such a possibility, the electronic control unit increases the fuel injection amount of the direct injector.

The downhole controller keeps the drill bit rotating by maintaining WOB during normal drilling operations, increasing WOB if sensed working pressure indicates that drill bit loading or torque is undesirably low, and reversing WOB by applying a spring force for retracting the drill bit if excessive working pressure or torque is sensed.

A washing machine capable of performing washing by increasing a water level when an overload of a motor is detected, and a control method thereof. The washing is performed by detecting an overload of the motor using a load detecting circuit and changing a water level to a highest water level when the overload is detected. Thus, a burning smell may not be caused from the motor by preventing stalling of the motor, and washing performance may be maintained since the motor is continuously operated without stopping.

Methods, systems and devices are described to avoid stalling during playback of an adaptive media stream delivered to a media player device over a network. The media device requests segments of the media stream that are received in a buffer.

By making adjustments based upon the rate of change in buffer utilization, sudden changes that could otherwise affect the viewer's experience can be avoided.

Content streaming systems, such as systems that use HTTP compliant requests to obtain media segments for presentation of the content on a device. These content streaming systems can be optimized to reduce latency to a low level so that live events can be streamed to receiving devices in such a manner so that the time between an action in the live event and the presentation of the action on a receiving device that receives the streamed content is less than about 10 seconds. A client device can use rendition reports to tune-in to a new rendition (at a first bit rate) after presenting a prior rendition (of a second bit rate) when switching between the different bit rates; also, for example, a client device can use playlist annotations that indicate independent frames to avoid downloading depending frame media segments when switching between different renditions.
