Abstract: An appliance, as provided herein, can include a direct current load and a current sensing circuit that can be coupled to the direct current load. The current sensing circuit can be configured to collect electrical data corresponding to the direct current load. The appliance can include one or more processors that can be coupled to the current sensing circuit. The one or more processors can be configured to identify at least one attribute of the direct current load based, at least in part, on the electrical data and activate at least one operation of the direct current load or the appliance based, at least in part, on identification of the at least one attribute of the direct current load.

Abstract: The adhering face mask is a device that allows the user to breathe filtered air without discomfort. It adheres to user's face with an adhesive gasket and creates a seal. The adhesive face mask creates an air pocket for the user preventing the mask from rubbing against the user's face. The filter housing gasket maintains a sealed air pocket when the filter housing assembly is attached. It comprises a filter housing assembly that uses a set of magnets embedded in it's body to attach to a matching set of magnets embedded in the adhering face mask body. It comprises a filter cartridge that adheres to the filter housing assembly and filters different kinds of air quality.

Abstract: Acrylamide-derived hydrogels and methods of fabrication thereof from an acrylic monomer, a crosslinking agent comprising an organosilicon compound, a polymerization initiator, a solvent and a polymerization accelerator, as well as their use in controlling circulation losses. The obtained hydrogels interact with the walls of the reservoir and exhibits an increase in viscosity, either at delayed times or in response to a given stimulus, such as changes in temperature, pressure, pH, salinity, using a simple and easily scalable methodology.

Abstract: A drive train connector assembly includes a first connecting structure and a second connecting structure. The first connecting structure has an attachment protrusion with first and second edges. The first edge extends in a first direction. The second edge extends in a second direction. Both directions are perpendicular to the rotational axis. The first and second directions define a first acute angle therebetween. The second connecting structure defines recessed area. The attachment protrusion fits into the recessed area. The recessed area defines third and fourth edges. The third edge extends in a third direction and the fourth edge extends in a fourth direction. The third direction and the fourth direction define a second acute angle. With the attachment protrusion installed within the recessed area the first and third edges are parallel to one another and the second and fourth edges are parallel to one another.

Abstract: A multipurpose protective cap for a transmission prior to and during assembly with a drive shaft has a base portion having a cylindrical cross-section of a first inner diameter. The base portion comprises a side wall defining the cylindrical cross-section and having an outer edge and an inner edge, and a membrane spanning the cylindrical cross-section of the base portion at the outer edge of the side wall. An insertion portion extends from the base portion opposite the outer edge, the insertion portion having a cylindrical cross-section of a second inner diameter, the second inner diameter smaller than the first inner diameter. A contamination removal portion is formed in an interior surface of the insertion portion and configured to remove debris as the drive shaft passes through the insertion portion. A handle extends from the side wall of the base portion.

Abstract: The present invention describes a scan adiabatic resistive calorimeter (SARC) 1 with ohm heating of the sample 20, which measures the heating enthalpy and is formed of an inner cylinder 11 and a couple of pistons 15 and 16, thus forming said elements a cylindrical chamber hermetically closed 10, which avoids that during its operation can be material losses by leaks. Pistons 15 and 16 have, in one of their ends an electrode 31 and 36 respectively and they pass the electrical heating flow through the sample 20. In reference to this electric flow, the applied power is calculated and therefore, the supplied heat to the sample 20, which is equal to the specific enthalpy. To assure that the whole of the electric flow is conducted through the sample 20, the inner cylinder 11 is electrically isolated.
