Component mounter, nozzle imaging method
A component mounter comprises first and second imaging systems, and a mounting head configured to hold a component by a nozzle. The first and second imaging systems irradiate light of first and second wavelengths, respectively, toward a working position to illuminate the nozzle located at the working position. The nozzle is imaged by the first and second imaging systems, respectively, that receive light having the first and second wavelengths, respectively, transmitted through first and second optical filters, respectively, after being irradiated on the working position. The first and second optical filters thus prevent light having wavelengths different from the first and second wavelengths from reaching the first and second imaging devices. Therefore, the nozzle can be imaged more precisely, since the influence of light different from the illumination light having the first and second wavelengths is suppressed by the first and second optical filters. |

Adaptive partition coding
Although wedgelet-based partitioning seems to represent a better tradeoff between side information rate on the one hand and achievable variety in partitioning possibilities on the other hand, compared to contour partitioning, the ability to alleviate the constraints of the partitioning to the extent that the partitions have to be wedgelet partitions, enables applying relatively uncomplex statistical analysis onto overlaid spatially sampled texture information in order to derive a good predictor for the bi-segmentation in a depth/disparity map.

Video on demand for audio/video recording and communication devices
In an A/V recording and communication device, the power configuration of the device is considered when determining a setting for a keep-alive interval of the device. If the device is connected to a reliable and continuous source of power, such as AC mains, then the keep-alive interval may be set to a very short duration, thereby reducing or eliminating any latency that the user might experience when attempting to remotely access the camera of the device. By contrast, if the device relies solely on a rechargeable battery for power, then the keep-alive interval may be set to a longer duration, thereby reducing the rate at which the rechargeable battery will be discharged. And, if the device is connected to an intermittent source of power, such as a solar panel, then the keep-alive interval may be set to a moderate duration to balance the competing interests of reducing latency and conserving battery life. |

Intelligent predictive stream caching
Some embodiments provide intelligent predictive stream caching for live, linear, or video-on-demand streaming content using prefetching, segmented caching, and request clustering. Prefetching involves retrieving streaming content segments from an origin server prior to the segments being requested by users. Prefetching live or linear streaming content segments involves continually reissuing requests to the origin until the segments are obtained or a preset retry duration is completed. Prefetching is initiated in response to a first request for a segment falling within a particular interval. Request clustering commences thereafter. Subsequent requests are queued until the segments are retrieved. Segmented caching involves caching segments for one particular interval. Segments falling within a next interval are not prefetched until a first request for one such segment in the next interval is received. Cached segments from the previous interval can be replaced in cache with segments for the current interval, thereby minimizing cache footprint utilization. |

Unobtrusive and dynamic DDoS mitigation
Some embodiments provide techniques for mitigating against layer 7 distributed denial of service attacks. Some embodiments submit a computational intensive problem, also referred to as a bot detection problem, in response to a user request. Bots that lack sophistication needed to render websites or are configured to not respond to the server response will be unable to provide a solution to the problem and their requests will therefore be denied. If the requesting user is a bot and has the sophisticated to correctly solve the problem, the server will monitor the user request rate. For subsequent requests from that same user, the server can increase the difficulty of the problem when the request rate exceeds different thresholds. In so doing, the problem consumes greater resources of the user, slowing the rate at which the user can submit subsequent requests, and thereby preventing the user from overwhelming the server. |
