Abstract: A system and method for producing an abrasive article includes a production tool configured to provide shaped abrasive particles to a resin coated backing. A first end and a second end of the production tool are spliced together to form a spliced area. The production tool includes a dispensing surface that includes a plurality of cavities formed between the first end and the second end and configured to receive and hold the shaped abrasive particles. The resin coated backing is configured to receive the shaped abrasive particles from the dispensing surface of the production tool and configured to receive further shaped abrasive particles to fill gaps in the shaped abrasive particles caused by an absence of the plurality of cavities in the spliced area.

Abstract: A distributed hydrogen energy system adds onto existing infrastructure of a localized renewable energy microgrid and utilizes excess generated energy to power an electrolyzer to produce hydrogen gas on site that is compressed and stored in a stationary pressure vessel. The stored hydrogen gas can be used directly within the local renewable energy microgrid wherein the stored hydrogen gas is converted to energy through use of one or more fuel cells or can be used in the context of a distributed energy system wherein the stored hydrogen gas is shared as part of a larger distribution network via pipeline or via one or more portable pressure vessels.

Abstract: A golf swing analyzer system for analyzing a golfer's golf swing. An inertial measurement unit (IMU) may be used to capture data regarding the swing. The IMU may be oriented along a hosel-axis and a face-axis to reduce the complexity of calculations to determine the path of the swing. Two IMUs may be used to permit correction of captured data, different orientations of the IMUs to increase accuracy of captured data, and a doubling of the captured data. The IMU may include a magnetometer that cooperates with a magnet that is adapted to indicate the time at or near impact of the head of the golf club with the golf ball. An LED system provides visual information to a user regarding the swing while the swing is being made.

Abstract: A system for electric vehicle charging and hydrogen fueling leverages existing infrastructure of a localized renewable energy microgrid and utilizes excess generated energy to power an electrolyzer to produce hydrogen gas on site that is compressed and stored in a pressure vessel. A first portion of the stored hydrogen gas may be used for hydrogen fueling of a fuel cell electric vehicle (FCEV) via a hydrogen fuel dispenser that is provided at a charging station. A second portion of the stored hydrogen gas may be converted into electricity through use of one or more fuel cells. The generated electricity may be used for charging a battery of a battery electric vehicle (BEV) via an electric vehicle charging dispenser that is also provided at the charging station.

Abstract: A software architecture and system for delivering selected sanitation protocols for multiple pathogens and pests for sanitizing a physical space. The software architecture and system generally includes a plurality of protocol identifiers linked to sanitation protocols arranged as pages in a protocol storage. Each sanitation protocol comprises a plurality of parameters arranged in tabular form for carrying out a sanitation process for one or more pathogens and/or pests. Also included are a control panel/display, controller, heat source, UV light source, and sensors. The protocol identifiers are displayed on the control panel/display and the controller retrieves the parameters of a selected sanitation protocol from the protocol storage. The controller operates in a closed-loop control arrangement with the heat source, UV light source, and sensors to automatically carry out a sanitation process according to the parameters of the selected sanitation protocol.

Abstract: A pneumatic oxygen conserver used with a single-tube cannula. The conserver includes a body having first and second cavities. A main diaphragm divides the first cavity into first and second chambers. An inlet passage delivers oxygen from a supply to the first chamber, and an outlet passage delivers oxygen from the first chamber to the cannula. The main diaphragm is movable between a closed position preventing oxygen flow through the outlet passage and an open position permitting flow. A first flow control passage connects the inlet passage and the second chamber, and a first flow control orifice in the passage restricts flow. A sensing diaphragm divides the second cavity into third and fourth chambers. A second flow control passage connects the second and third chambers, and a second flow control orifice in the passage restricts flow. The sensing diaphragm is movable between a closed position preventing flow through the second passage and an open position permitting such flow.

Abstract: A polyvinyl acetal sponge formed from a high molecular weight polyvinyl alcohol is used for forming a splint for a portion of body, such as during healing of a bone fracture or other injury. The sponge is maintained in a softened condition in the presence of vapors of a softening agent such as ethyl alcohol within a sealed pouch. Upon removal from the pouch, the sponge is applied to the body portion and it hardens to form the splint as the softening agent vapors dissipate.

Abstract: A reliable, pulse-flow supplemental oxygen apparatus for alleviating respiratory ailments is provided which yields substantial savings in oxygen while giving the patient the physiological equivalent of a prescribed continuous stream of oxygen. The apparatus preferably includes a demand oxygen valve operated in a pulse mode by means of electronic control circuitry which, through an appropriate sensor, monitors the patient's breathing efforts and gives a variable "custom tailored" pulse volume of oxygen to the patient during the very initial stages of each inspiration.
