Abstract: Methods and systems are provided for testing three-dimensional (3D) stacked dies of integrated circuits (ICs). The methods and systems receive, by test signal routing logic implemented on a first die, a first die test signal, the test signal routing logic operating in an elevate mode or turn mode. The methods and systems receive a second die test signal from a second die and route the first die test signal to an external device in the turn mode. The methods and systems route the second die test signal received from the second die to the external device in the elevate mode.

Abstract: A dongle for setting the position of a throttle plate in a throttle body has a process that is driven by a power supply regulated to 5 Vdc to generates a graphic representation of an acceptable range for engine revolutions per minute and throttle plate position within a throttle body. A comparator extracted information from an interrogation of the engine control monitor to determine if the throttle body is within the acceptable range. A signal is generated to indicates the presence or absence of an acceptable range.

Abstract: A spring-loaded hinge assembly including a hinge support bracket and a leaf that is pivotally mounted to the hinge support bracket. A coil spring is supported on a spring support member, which includes a pivot bush. The coil spring applies a biasing force to the spring support member, which operates to push the pivot bush against a cam on the leaf. A lock configured to rotate between locked and unlocked positions includes a finger that engages an engagement feature on the hinge support bracket when the lock rotates to the locked position as the leaf swings toward the open position. In the locked position, the lock holds the coil spring in a partially compressed, pre-load condition and the pivot bush at a partially retracted position relative to the cam until the lock is subsequently released by contact between the cam and the pivot bush during subsequent closure.

Abstract: A contactless laundry treating apparatus may include a cabinet having a front panel defining an access opening configured to receive laundry items, door attached to the front panel via a hinge assembly, where the hinge assembly may include a hydraulic system arranged on an interior of the front panel within the cabinet configured to engage with a connecting hook arranged within the door to selectively apply an outward force on the connecting hook to open the door and an inward force on the connecting hook to close the door.

Abstract: An IC chip test engine selects an instrument of an IC design based on an instrument access script, wherein the selected instrument comprises an IP block and a test data register (TDR) logically arranged upstream from the IP block. The IC chip test engine can also identify a set of SIBs gating access to the selected instrument and select a scan chain for operating the set of SIBs to control access to the selected instrument. The IC chip test engine augments the scan chain with data to cause at least a furthest downstream SIB of the set of SIBs that gates access to the selected instrument to transition to an opened state. The IC chip test engine can generate a set of load vectors for the scan chain to load the TDR of the selected instrument with data to apply a respective test pattern to the IP block.

Abstract: Techniques for automating the migration of a web service implementation to a service provider system are described. The automated migration of a web service implementation to a service provider system can include the migration of an API specification to an API gateway service, the migration of source code to a virtual compute service, and optionally the migration of other web service components to other services provided by the service provider system. The migrated web service can be accessed at the service provider system using a URL or other identifier generated by the service provider system. In this manner, the external functional behavior of the web service can remain the same while internally taking advantage of the benefits offered by services of a service provider system.

Abstract: A manipulator arm for moving a load from a first position at a first elevation, to a second position at a second elevation, provides a base and defines plural spaced apart axle holes. A fulcrum lever link formed of a channel beam defines plural spaced apart axle holes. A first load member, and two support members extend between, and pivotally interconnect, the base plate and the fulcrum lever link and define a quadrilateral lift frame about the pivotal interconnections. An actuator operatively communicates between the first load member and the fulcrum lever link and the fulcrum lever link provides mechanical advantage to the actuator to cause the quadrilateral lift frame to change from a first configuration at the first position to a second configuration at the second position.

Abstract: A migration system or service may implement event-driven replication for migrating a computing resource from a source network to a destination network. A replication event may be detected to obtain a state of a data volume for a computing resource hosted in a client network. A request to a replication agent hosted in the source network may instruct the replication agent to copy at least some of the data of the data volume and send the data to the destination network. The migration service may generate a state of the data volume from the received data in a format that is operable to host the computing resource in the destination network and store the generated state of the data volume.
