Predictive scaling of computing resources
The described technology is generally directed towards predicting a need for provisioned (e.g., cloud computing) resources so that the provisioned resources are proactively provisioned and operational before their actual need.

Monitoring of replicated data instances
Replicated instances in a distributed computing environment provide for automatic failover and recovery. A component monitors the status of event processors in a set or bucket and handles the failure of an event processor. For a large number of instances, the data environment can be partitioned such that each monitoring component is assigned a partition of the workload. At intervals, each event processor sends a “heartbeat” message to the event processors in the bucket covering the same workload partition, to inform the other event processors of the status of the event processor sending the heartbeat. If it is determined that a heartbeat is received from each event processor in the bucket, a current process can continue. In the event of monitoring component failure, the instances can be repartitioned, and the remaining monitoring components can be assigned to the new partitions to substantially evenly distribute the workload. |

Circuits and methods for detecting and unlocking edge-phase lock
A receiver samples an analog, multi-level, pulse-amplitude-modulated signal using a clock-and-data recovery circuit (CDR) that samples the signal against adaptively calibrated symbol-decision thresholds in time with a clock signal that is phased aligned with and locked to the signal. The CDR can erroneously align the clock signal to inter-symbol edges of the signal, a condition called “edge lock,” rather than on the symbols themselves. A transition-type detector senses the edge-lock condition and unlocks the CDR, which can then realign the clock signal, this time on the symbols rather than the inter-symbol edges. The receiver can also respond to the edge-lock condition by kick-starting a shift of symbol-decision threshold that helps the CDR settle more quickly on correct symbol-decision thresholds. |

Distributed cryptographic management for computer systems
An administrator installs a key management agent on a previously approved client machine. The agent is started on the client machine, which posts requests for keys to a central key management service. The central key management service logs requests posted to it by clients, and checks for existing pre-approval records. If none are found, a message is typically sent to an approver for the requesting client machine. When a request is verified as approved, the request is flagged for further processing. The supported systems continuously or periodically look for records flagged for processing, use requests to generate keys and other appropriate elements for the requesting client machine, and post keys and other elements to the key management database. The key management agent polls the central key management service periodically until finding the expected key file, which it downloads and installs into a protected file location on the client machine. The key management agent periodically sends status messages to the central key management service, which tracks expected behavior of the client machine and/or key management agent. |

III-V light emitting device with pixels enabling lower cost through-layer vias
A III-V light emitting device with pixels (mesa regions) specifically designed to enable lower cost through layer vias is disclosed for reduced cost of manufacture of the device. Reduction of cost of manufacture is achieved by having non-uniform width trench regions formed during pixel etch for the multi-pixel array part of the device. Through-layer vias are specifically formed in the wider part of the trench regions using cheaper lithography toolset enabled by the larger via critical dimension achievable in the wider part of the trench regions (as compared to narrow part of the trench regions). Larger via critical dimension enables improved electrical (and consequently optical) performance of the device due to better overlay control as well as lower via resistance. |

Ultra-dense array of LEDs with half cavities and reflective sidewalls, and hybrid bonding methods
In one approach, an LED array uses a combination of a half cavity and straight reflective sidewalls to improve the power distribution so that more light falls within the collection angle of the projection optics. From the bottom upwards, the LEDs in the array include a reflector, a thinner p-layer and a thicker n-layer. An active region (such as quantum wells) between the p-layer and the p-layer generates light. Without additional structures, the generated light would have an isotropic distribution and not much of the light would fall within the collection angle of the projection optics. However, the bottom reflector and p-layer form a half cavity for the light emitted from the active region. This alters the angular power distribution. Straight reflective sidewalls extending from the active region upwards into the n-layer further reflect light from the altered power distribution into the collection angle of the projection optics. |
