Abstract: A method of forming a composite part from a mufti-ply prepreg composite charge comprises reducing pressure inside a bladder, located in a chamber that is at atmospheric pressure, below the atmospheric pressure. The method also comprises placing the multi-ply prepreg composite charge, having a first shape, in the chamber and reducing pressure inside the chamber below the atmospheric pressure. The method additionally comprises, while maintaining pressure inside the chamber below the atmospheric pressure, expanding the bladder within the chamber by increasing pressure inside the bladder to the atmospheric pressure, so that the multi-ply prepreg composite charge is compressed between the bladder and a forming tool, which is located inside the chamber, and the multi-ply prepreg composite charge is configured by the forming tool to a second shape, different from the first shape. The method also comprises curing the multi-ply prepreg composite charge, having the second shape.

Abstract: A multi-band antenna has a feed point, a grounding location, a first portion for low band operation, a second portion for low band operation, and one or more portions for high band operation. The ground reference of the feed point for the multi-band antenna is connected to a separate object that may provide a base for the multi-band antenna. The feed point of the multi-band antenna may be spaced above the base and have a space between the feed point and a location for the ground point. The low band portion has multiple resonances that are often odd multiples of the lowest resonant response. The portions that resonant most dominantly in the high band often have multiple resonances that are even multiples of the lowest high band resonance. The multi-band antenna has resonances spaced closely enough to appear to be a wide band antenna above the fundamental high band resonance.

Abstract: A method of operating a solar energy plant and a solar plant are disclosed. Thermal energy produced in the plant is used to heat a first volume of water and charge a hot store in the plant. Electricity produced in the plant operates a heat engine or other device, such as a refrigeration unit, to extract heat and consequently cool a second volume of water and charge a cold store. As desired, energy is transferred from the hot store to a heat engine and energy is transferred from the heat engine to the cold store to operate the heat engine to produce power in the plant.

Abstract: Some noise compensation methods involve receiving microphone signals corresponding to ambient noise from a noise source location in or near an audio environment, determining or estimating a listener position in the audio environment and estimating at least one critical distance, which is a distance from the noise source location at which directly propagated sound pressure is equal to diffuse field sound pressure. Some examples involve estimating whether the listener position is within the at least one critical distance and implementing a noise compensation method for the ambient noise based, at least in part, on an estimate of whether the listener position is within the critical distance.

Abstract: The recent pandemic has resulted in a desire to avoid human-to-human contact where possible. Purchasing items from a brick-and-mortar store traditionally involves close human interaction and touching items that have been touched by others. Now, to reduce human-to-human interaction, a bank of compartments is described into which items are placed by staff members for later collection by customers. After agreeing a purchase, a staff member places the purchased item in a compartment. The customer uses a smartphone to announce their arrival at the bank of compartments and provide authentication, at which point the compartment with the item is identified to the customer. The compartment automatically unlocks and opens allowing the customer to obtain the item without touching the compartment or its door. Deposits of purchased items are made via the bank for exchange, repair or refund. Each compartment may sanitize itself and its contents with UV-C light.

The generation of the read-only copy of the bucket prevents deletion of the snapshot.

Abstract: It has been unexpectedly discovered that the addition of a natural or other pozzolan to non-spec coal ash significantly improves the properties of the non-spec coal ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C coal ash. The natural pozzolan may be a volcanic ejecta, such as pumice or perlite. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec coal ash into certifiable Class F coal ash. Additionally, this disclosure provides a method of converting a Class C coal ash to a more valuable Class F coal ash. This discovery will extend diminishing Class F coal ash supplies and turn non-spec coal ash waste streams into valuable, certified coal ash pozzolan which will protect and enhance concrete, mortars and grouts.
