Methods and apparatus for high speed camera
In exemplary implementations of this invention, a camera can capture multiple millions of frames per second, such that each frame is 2D image, rather than a streak. A light source in the camera emits ultrashort pulses of light to illuminate a scene. Scattered light from the scene returns to the camera. This incoming light strikes a photocathode, which emits electrons, which are detected by a set of phosphor blocks, which emit light, which is detected by a light sensor. Voltage is applied to plates to create an electric field that deflects the electrons. The voltage varies in a temporal “stepladder” pattern, deflecting the electrons by different amounts, such that the electrons hit different phosphor blocks at different times during the sequence. Each phosphor block (together with the light sensor) captures a separate frame in the sequence. A mask may be used to increase resolution. |

Performance isolation for clouds
Traffic in a cloud is controlled by the nodes participating in the cloud. Tenants of the cloud each have a ratio. On any given node, a current transmission rate of the node is allocated among the tenants of the node, or more specifically, their execution units (e.g., virtual machines) on the node. Thus each tenant receives a predefined portion of the transmission capacity of the node. The transmission capacity can vary as conditions on the network change. For example, if congestion occurs, the transmission capacity may be decreased. Nonetheless, each tenant receives, according to its ratio, a same relative portion of the overall transmission capacity. |
