Abstract: The disclosure is directed to a switching apparatus that can reduce leakage in instrument switching at a test node probing a device under test. In some implementations, a buffer can sense a voltage at the test node and drive a guard node to track the voltage to cancel leakage. That apparatus can include a power supply providing a floating supply node referenced to the guard node and a bias network configured to bias terminals of a Photo-MOSFET relative to the guard node so that the Photo-MOSFET element floats near the guard potential, reducing voltage across insulating structures associated with the photo-device. Additionally, some implementations may include a control path, driven by a control circuit that can selectively enable and disable current through the Photo-MOSFET while maintaining electrical isolation with the floating domain.

Abstract: The disclosure is directed to systems and method with improved coordination for multiple parametric test channels. The system can be configured to receive a testing routine and distribute test operations to a plurality of test channels comprising channel processors, testing circuits coupled to test pins configurable to be connected to the device under test (DUT), and trigger interfaces coupled to the testing circuits. Additionally, some implementations can include a hub device coupled to the processing system and to the trigger interfaces, the hub device includes programmable logic gates configured to define a trigger group including at least two of the trigger interfaces and to generate trigger signals according to the testing routine. Further, at least a portion of the channel processors perform operations according to the testing routine upon receipt of the trigger signals. The disclosure enables synchronized yet autonomous multi-channel testing that improves test throughput and timing accuracy.

Abstract: The disclosure is directed to range-finding systems, apparatuses, circuitry, and methods for a parametric tester. A forced test current can be conducted through a series-connected plurality of range resistors between an input amplifier and a test interface coupled to a test channel terminal. Diodes coupled in parallel with respective range resistors can conduct when a voltage across a corresponding range resistor exceeds a conduction threshold, thereby bypassing a portion of the test current around that range resistor to support operation across multiple current ranges without range-selection switches in the forcing path. Respective amplifiers can sense voltages associated with corresponding range resistors and provide amplifier output signals to inputs of a multiplexer.

Abstract: The disclosure describes systems and apparatuses for semiconductor testing equipment. A system may include an AC-DC power supply. The system may include a test head mounted on the prober interface. The test head may be coupled to the AC-DC power supply and may include a panel including a plurality of ports and disposed on a first end of the test head. The test head may include a probe card interface. The probe card interface may include a plurality of spring pins and an electrical contact assembly. The probe card interface may be disposed on a second end of the test head and configured to connect to an electrical connection point. The system may include a manipulator. The manipulator may be configured to move the test head.

Abstract: The disclosure describes systems and methods for parametric multi-channel testing of semiconductor devices. A system provides multiple test channels that include a pulse resource and a measuring resource with high-current (HC) and low-current (LC) switches coupled to a potential node connected to a testing pin. The pulse resource includes a first branch with a pulse generator, programmable-gain amplifier, switches for different branches or operations providing pulse current/voltage monitoring and a high-speed switch. A mode switch can be incorporated to selectively connect the potential node to the pulse resource for pulse testing, to the measuring resource with the HC switch closed for high-potential testing, or to the measuring resource with the LC switch closed for low-potential testing.

The method further includes determining a plurality of possible shipping configurations from the plurality of predetermined configurations, each one of the plurality of possible shipping configurations comprising an assignment of the shipments into or as one of the plurality of unit load devices, and a location of each of the plurality of unit load devices within the cargo hold of the aircraft. The method further includes determining one of the plurality of possible shipping configurations that satisfies a rule.

Abstract: A computer based system for remapping prime class seat bookings is disclosed. The system remaps prime class bookings a floor class, or if the floor class is closed, into a higher, displacement class. Via remapping, airline systems, such as inventory management systems, revenue management systems, and the like, may better account for the true value of prime class bookings.

Abstract: A computer-based system for unobscuring and/or unconstraining demand is disclosed. Via use of the system, actual airline seat bookings may be restated in an unobscured and/or unconstrained form, facilitating improved demand forecasts for subsequent seat bookings. In this manner, seat protects may be better allocated to align with actual demand, thus increasing revenue.

Abstract: The disclosed computer-implemented method includes identifying a target networking device communicatively connected to a cluster of networked server instances. The networked server instances are configured to consume network telemetry messages. The method further includes applying a shared lock to the target networking device, so that only a single networked server instance has access to network telemetry messages produced by the target networking device. The method also includes replicating the network telemetry messages produced by the locked target networking device to other server instances in the cluster, and then diverting requests for network telemetry messages from the locked target networking device to another server instance in the cluster of networked server instances. This allows the other server instance in the cluster to service the diverted telemetry data requests for the locked target networking device using the replicated network telemetry messages.
