Abstract: The present disclosure provides methods of forming products using one or more lasers. In at least one aspect, a method for powder bed additive manufacturing includes defining a uniform pitch raster path for a laser traveling at a predetermined rate of travel. The raster path alternates back and forth within a strip width of less than 0.5 mm such that the laser's power density level is at least 80 percent of maximum power and the predetermined rate of travel yields a travel speed in the scan width direction of not less than 1,000 mm/s. The method includes depositing a layer of powder onto a substrate and causing the laser to solidify a quantity of the powder according to the defined raster path and the laser power setting.

Abstract: Methods and apparatuses for scheduling tasks with a job scheduler are disclosed. In one embodiment, the method comprises: tracking a number of active tasks for each key of a plurality of keys; writing, by a scheduler, a query to identify a next scheduled task among a plurality of scheduled tasks ordered by time in a task queue, the query having an index that excludes tasks associated with a list of one or more keys of the plurality of keys that have a count of active tasks greater than a first limit associated with each key; querying, by a scheduler, the task queue using the query to identify the next scheduled task among the plurality of scheduled tasks, the next scheduled task being associated with a key not excluded by the query; and executing the next scheduled task.

Abstract: A system for controlling a high-power drive device includes a fault detection integrated circuit product configured to provide an indication of a fault condition associated with the high-power drive device to a first terminal in a first voltage domain in response to detecting the fault condition in a second voltage domain. The system includes a gate driver controller integrated circuit product configured to drive a second terminal coupled to a control node in a second voltage domain based on a control signal and an enable signal received from a third terminal in the first voltage domain. The second voltage domain is higher than the first voltage domain. The system may include a redundant fault reporting integrated circuit product or an additional fault detection integrated circuit product configured to detect a second fault condition in the second voltage domain that is different from the fault condition.

Abstract: A rib foot cleat for sealing around a stringer passing through a rib mouse hole in an aircraft assembly. The rib foot cleat has a body for attaching to a rib at a rib mouse hole and defines a cleat channel configured to be arranged over the stringer. The rib foot cleat also has an injection hole through the cleat body which is in fluid communication with the cleat channel, to allow sealant material to be injected through the injection hole in to the cleat channel for sealing around the stringer.

Abstract: A high temperature pressure capacitor is fabricated utilizing two high temperature substrate wafers. The substrates may be silicon carbide (SiC) or aluminum nitride (AIN). The first substrate has a metal conductive plate positioned on a top surface thereof. The top surface and plate are covered with a dielectric layer. The second substrate has a plate accommodating recess on the top surface thereof. Deposited in the recess is a second conductive plate. The first and second wafers are bonded together via the dielectric layer where the first and second plates face each other. Upon application of a force to the first wafer the diaphragm portion of the first wafer deflects causing the first plate to move and thereby varying capacitance. An inductor may be fabricated on a bottom surface of the second wafer to provide an LC circuit whose resonant frequency varies as a function of capacitance and therefore as a function of pressure.

Abstract: In a data handling system having a radially-dependent track incongruity between data surfaces, at least some tracks are logically mapped so that tracks on different data surfaces correspond with one another. The correspondence is defined by the mapping so as to shorten an average headswitch seek. For example, a logical track mapping of first and second non-coaxial track sets can be defined so as to optimize a headswitch seek within each of many intermediate logical cylinders identified in the mapping.

Abstract: An apparatus and method of tracking repeatable runout in a disc drive servo loop is provided in which a feedforward signal having harmonic components that are updated at a sample rate that is a fraction of a servo sector sample rate is employed during track following.
