Nozzle performance analytics
A pick and place nozzle performance analytics system streams production data from pick and place machines used in electronic assembly to a cloud platform as torrential data streams, and performs analytics on the production data to track, visualize, and predict performance of individual nozzles in terms of rejects or miss-picks. The analytics system generates a performance vector for each nozzle based on the collected production data, the performance vector tracking both the accumulated rejects and the percentage of rejects as respective dimensions of an x-y plane. The system monitors and analyzes the trajectory of this vector in the x-y plane to predict when performance degradation of the nozzle will reach a critical threshold. In response to predicting that nozzle performance degradation will exceed a threshold at a future time, the system can generate and deliver notifications to appropriate client devices. |

Content prefetching and cache management
The presentation of content items within a hosting item is typically performed by on-demand retrieval of the content item from a content server. However, on-demand retrieval may impose an undesirable delay in the presentation of the content; may spontaneously alter the layout of the hosting item; and/or may involve an expedient but unsophisticated selection among the content items of a content store (e.g., random selection), resulting in the presentation of irrelevant and/or redundant content. Instead, a device may prefetch content items into a content cache, such that when a user later requests to view a hosting item, the device may insert a content item selected from the content cache. The device may also notify the content server when a content item has been presented to the user; by marking the content item as such, the content server may provide additional, fresh content for the device content cache. |

Resource response expansion
The described technology is directed towards returning expanded data, beyond the data that was specifically requested, to a client, in order to reduce or eliminate likely subsequent requests for more data. Client requests for data items are processed by expansion rule logic to find an expansion rule set (e.g., file) corresponding to the identified data item. The rule set is used to expand requests for certain data items into expanded requests that return more data items than those requested. Client devices receive, cache and (often) use the cached expanded data items, which thereby reduces the overall number of requests to the data service. Expansion rules may be based upon observations (e.g., machine learned and/or manual) of request patterns, so as to reasonably predict which data item or items clients will likely next need, and return those as expanded data items in anticipation of their need. |

High-power fiber cladding power stripper
A high-power fiber cladding power stripper comprises a core unit, a cladding layer, a grating structure, and a jacket. The core unit is an optical conductive material. The cladding layer is disposed outside the core unit, wherein a refractive index of the cladding layer is lower than that of the core unit. The grating structure, disposed outside the cladding layer, is for producing diffraction effects. The jacket surrounds and protects the core unit, the cladding layer, and the grating structure. Hence, in a high-power fiber laser system, the cladding power stripper can be utilized for removing residual pump energy before the laser light entering an output collimator. |
