Abstract: An emergency ventilation system ventilates a patient and includes a chamber housing defining a breathing chamber; a piston; and a motor operably connected to the piston. The motor applies an exhalation force to move the piston in an exhalation direction applies an inhalation force to move the piston in an inhalation direction. The piston increases air in the breathing chamber as the exhalation force is applied and decreases air in the breathing chamber as the inhalation force is applied. An exhalation check valve allows airflow from the air source to the breathing chamber and not to allow airflow from the breathing chamber to the air source as the inhalation force is applied. An inhalation check valve allows airflow from the breathing chamber to the air output and not to allow airflow from the air output to the breathing chamber as the exhalation force is applied.

Abstract: A method and apparatus for operating cooling and heating equipment are disclosed. For example, the method receives data that is captured by at least one sensor deployed at a location of a plurality of locations, wherein the data is associated with at least one parameter of an equipment, wherein the equipment is deployed at the location, receives atmospheric data for the location, receives utility rate data for the location, monitors the at least one parameter of the equipment, the atmospheric data, and utility rate data for the location, determines for the at least one parameter of the equipment, a remedial analytics is needed to be performed, when a deviation from a baseline is detected that is greater than a threshold for a maximum deviation from the baseline that is established for the at least one parameter, performs the remedial analytics, and generates a recommendation for a remedial action based on a result of the remedial analytics that is performed.

Abstract: An assembly for mounting an excavating tooth particularly suited for a dredge cutterhead includes a base, an adapter, and a lock. The base includes a convex, curved bearing surface that abuts a concave, curved bearing surface on the adapter. The curved bearing surfaces are able to maintain substantially full contact with each other under transverse loading.
