Patent number: 11858073Abstract: Methods and systems for creating and controlling an AC output for welding, plasma cutting or heating are provided. One embodiment of the present disclosure achieves a desired square wave AC output and reduces the number of circuit components needed by combining components of a buck converter and a full bridge inverter. Current flow paths through a power control circuit that are generated via switching of transistors in the circuit on and off are provided. In one embodiment, a pulse width modulation leg, which controls the level of current flow through an inductor, is provided. Certain embodiments include a bidirectional buck converter that converts an unregulated DC flow to a regulated DC flow through an inductor. In one embodiment, a steering leg is provided, which controls a direction of current flow through the inductor. Additionally, an output clamp circuit, which suppresses the parasitic load inductance during polarity reversal is provided.Type: GrantFiled: February 4, 2020Date of Patent: January 2, 2024Assignee: Illinois Tool Works Inc.Inventors: Michael David Madsen, Quinn William Schartner

Patent number: 11340791Abstract: Apparatus comprises source circuitry to provide data items; buffer circuitry having a set of buffer entries to hold one or more data items, provided by the source circuitry, for delivery to one or more destinations within a respective delivery latency, in which a buffer entry holding an initial data item becomes available to hold another data item in response to delivery of the initial data item to its respective destination; and control circuitry to control acceptance of data items from the source circuitry for holding by the buffer circuitry, the control circuitry being configured to control the buffer circuitry to accept a given data item when: (i) a buffer entry is available to hold the given data item and (ii) the delivery latency of data items including the given data item held by the buffer circuitry is such that at least a threshold number of buffer entries may be made available within no more than a threshold availability period.Type: GrantFiled: January 14, 2020Date of Patent: May 24, 2022Assignee: Arm LimitedInventors: David Madsen, Richard F Bryant

SEED CONGLOMERATION: A DISRUPTIVE INNOVATION TO REDUCE CLEANING REQUIREMENTS OF SMALL SEEDED SPECIES
Publication number: 20220078965Abstract: Materials and methods are disclosed for conglomerating low-purity small seeds, clay-binder, and aeration media into a particle. Through this process a low purity seed does not inhibit seed flow through planting equipment because the seed and associated non-seed parts are formed into particles that have vastly improved flow and aerodynamic properties over untreated seed.Type: ApplicationFiled: October 28, 2021Publication date: March 17, 2022Inventors: Matthew David Madsen, Rhett Michael Anderson, Benjamin William Hoose -

Patent number: 10705022Abstract: An optical head for a Raman spectroscopy system includes a housing an input configured to allow input radiation of a selected wavelength into the housing, a first lens disposed in an end of the housing to allow the input radiation to emit from the housing through the first lens and to receive reflected radiation including specular reflection and diffuse reflection, and a second lens disposed in the housing and configured to receive reflected radiation from the first lens. The optical head includes an output configured to receive the reflected radiation from the second lens. The optical head includes a blocking mirror disposed in the housing between the first lens and the second lens. The blocking mirror is configured and positioned to direct the radiation from the input to the first lens. The blocking mirror blocks at least a portion of specular reflection from reaching the second lens but allows diffuse reflection to the reach the second lens.Type: GrantFiled: August 24, 2016Date of Patent: July 7, 2020Assignee: Goodrich CorporationInventors: David Madsen, Alexander J.

Patent number: 10545879Abstract: An apparatus and method are provided for handling access requests. The apparatus has processing circuitry for processing a plurality of program threads to perform data processing operations on data, where the operations identify the data using virtual addresses, and the virtual addresses are mapped to physical addresses within a memory system. The cache storage has a plurality of cache entries to store data, an aliasing condition existing when multiple virtual addresses map to the same physical address, and allocation of data into the cache storage being constrained to prevent multiple cache entries of the cache storage simultaneously storing data for the same physical address.Type: GrantFiled: March 26, 2018Date of Patent: January 28, 2020Assignee: Arm LimitedInventors: Richard F.
