Abstract: Implementations of the disclosure include a lid for covering a vessel, having a cover portion and a base portion, and methods of operating such a lid. The cover portion and the base portion may be separate individual pieces. In some implementations, the cover portion is adapted to slide along the base portion between an open position and a closed position. In some instances, the cover portion slides along an arcuate path. In some implementations, when the cover portion is in a cover-removal position, it can be separated from the base portion without separating the base portion from the vessel. In such implementations, when the cover portion is in a lid-removal position, the cover portion and the base portion can be separated from the vessel while remaining attached to one another.

Abstract: Inertial sensor having a body with first and second cavities on opposite sides thereof, a sensing element in the first cavity, electronic circuitry in the second cavity, electrical conductors interconnecting the sensing element and the circuitry, and leads connected electrically to the circuitry and extending from the body for mounting the sensor and making connections with the circuitry.

Abstract: Air-treatment apparatus and methods are disclosed that are especially suitable for treating the air in a room or other dwelling or working space. An apparatus embodiment of the subject apparatus includes a housing having air-intake and air-output openings. A gas-filter assembly inside the housing receives air entering the air-intake opening and includes a dual-media filter element having a matrix of fibers to which particles of activated carbon are adhered at mutual points of contact without using an extraneous binder. As air passes through the gas-filter assembly, the carbon particles adsorb odor compounds from the air. At least one electrostatic 3-dimensional (E3D) filter assembly downstream of the gas-filter assembly includes a respective charging element sandwiched between dielectric-fiber filters sandwiched between two respective electrically conductive screens. The screens are electrically grounded while the charging element (which is conductive) is connected to a source of high-voltage DC power.
