Abstract: Improved methods for retrieval of content from CDNs is provided that includes a rendezvous controller that receives information of an identification of content being requested and an estimated location of a content requesting device. Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server.

Abstract: A work machine, such as a hauler at a mining site, includes a conductive linkage connected to a conductor rod for receiving multiple poles of electrical power from a current collector sliding on a surface of a power rail. The conductive linkage includes trailing arms substantially parallel to each other and attached by lower joints to the current collector and by upper joints to the conductor rod. The lower joints and the upper joints have multiple axes of rotation and enable the trailing arms to move laterally and vertically with respect to the surface of the at least one power rail in response to movement of the work machine, while conducting the electrical power from the current collector to the conductor rod.

Abstract: Disclosed herein is a system for improving the user experience in the face of a regression by returning resources that offer a service to a “last known good” upgrade. In other words, the state of the resources is reconfigured to scale back from recent upgrade(s), the deployments of which likely caused the regression, to a previous upgrade that is known to have little or no effect on the user experience. To identify a problem, the system collects performance data from different resource units that make up a cloud-based platform. The performance data is collected for each upgrade event in a sequence of upgrade events that are currently deployed or being deployed. The system continually tracks and analyzes qualification data collected for each of the deployed upgrade events. The system can tag an upgrade event as the last known good upgrade event when the collected qualification data satisfies predefined qualifications.

Abstract: Techniques and mechanisms for coupling chiplets to microchips utilizing active bridges. The active bridges include circuits that provide various functions and capabilities that previously may have been located on the microchips and/or the chiplets. Furthermore, the active bridges may be coupled to the microchips and the chiplets via “native interconnects” utilizing direct bonding techniques. Utilizing the active bridges and the direct bonding techniques of the active bridges to the microchips and the chiplets, the pitch for the interconnects can be greatly reduced going from a pitch in the millimeters to a fine pitch that may be in a range of less than one micron to approximately five microns.

Abstract: A reach matrix scheduler circuit for scheduling instructions to be executed in a processor is disclosed. The scheduler circuit includes an N×R matrix wake-up circuit, where ‘N’ is the instruction window size of the scheduler circuit, and ‘R’ is the “reach” within the instruction window of the matrix wake-up circuit, with ‘R’ being less than ‘N’. A grant line associated with each instruction request entry in the N×R matrix wake-up circuit is coupled to ‘R’ other instruction entries among the ‘N’ instruction entries. When a producer instruction in an instruction request entry is ready for issuance, the grant line associated with the instruction request entry is activated so that any other instruction entries coupled to the grant line (i.e., within the “reach” of the instruction request entry) that consume the produced value generated by the producer instruction are “woken-up” and subsequently indicated as ready to be issued.

Abstract: A high pressure gas lift compressor system and method of using the system for supplying compressed gas to multiple wells are provided. The system includes a compressor having multiple compressor cylinders. Each cylinder has its own gas inlet line and dedicated gas outlet line that supplies compressed gas from that cylinder directly to a wellbore to provide artificial gas lift. Each cylinder also has its own control valve upstream of the cylinder to control the suction pressure to the cylinder. A desired gas flow rate to each well may be input, and the control valve is adjusted accordingly to achieve the flow rate. By inputting a flow rate for each separate cylinder, the flow rate to each well may be independently controlled.

Abstract: Methods and systems for recipient-assisted recharging during delivery by an unmanned aerial vehicle (UAV) are disclosed herein. During a UAV transport task, a UAV determines that the UAV has arrived at a delivery location specified by a first flight leg of the transport task. The UAV responsively initiates a notification process indicating that a recipient-assisted recharging process should be initiated at or near the delivery location. When the UAV determines that the recipient-assisted recharging process has recharged a battery of the UAV to a target level, and also determines that a non-returnable portion of the payload has been removed from the UAV while a returnable portion of the payload is coupled to or held by the UAV, the UAV initiates a second flight segment of the transport task.
