Abstract: Apparatuses, systems, and methods are presented for nesting lid containers. An apparatus includes a first container that includes a bottom, at least one container side wall located perpendicular to a first surface of the bottom and extending from the first surface of the bottom to an open top to form a container, at least one divider side wall configured to partition the container into a plurality of sections, and a suction-type element located on a second surface of the bottom opposite the first surface, the suction-type element configured to selectively adhere the first container to a surface. An apparatus includes a second container that is configured to receive the at least one container side wall of the first container and selectively be secured to the first container such that the second container acts as a lid for the first container.

Abstract: Apparatuses, systems, and methods are presented for nesting lid containers. An apparatus includes a first container and a second container that includes a bottom, at least one side wall coupled perpendicular to an edge of the bottom and extending from the bottom to an open top to form a container, and a securing element coupled to a side of the bottom opposite the at least one side wall for preventing movement of the container while placed on a surface. A second container is insertable into a first container where at least one side wall of the first container is configured to receive at least one side wall of the second container such that the second container acts as a lid for the first container.

Abstract: Apparatuses, systems, and methods are presented for restraining a user. An apparatus includes an underlay segment and a barrier panel. The underlay segment is positionable underneath at least one of the shoulders, the head, the back, and the buttocks of the user lying in the supine position. The barrier panel is coupled to the underlay segment and is extendable around the chest of the user to form a partition between an upper body portion and a lower body portion of the user. A proximal edge of the barrier panel is shaped to contour and rest on the chest or abdomen of the user so that engagement between the proximal edge and the user supports a distal edge of the barrier panel to extend outwardly and upwardly from the upper body portion of the user. The barrier panel is foldable.

Abstract: An apparatus for preventing a baby from interfering with a diaper changing process. The apparatus includes an underlay segment and a barrier panel. The underlay segment is positionable underneath at least one of the shoulders, the head, the back, and the buttocks of the baby lying in the supine position. The barrier panel is coupled to the underlay segment and is extendable around the chest of the baby to form a partition between an upper body portion and a lower body portion of the baby. A proximal edge of the barrier panel is shaped to contour and rest on the chest or abdomen of the baby so that engagement between the proximal edge and the baby supports a distal edge of the barrier panel to extend outwardly and upwardly from the upper body portion of the baby. The barrier panel is foldable.

Abstract: An angular position sensor, suitably for use in a helmet sight system, comprising a link member (3) connected by first and second (5 and 49) coupling means respectively to first and second fixing means (7 and 57, 59, 63) whereby the sensor may be attached between two bodies (1 and 61) whose relative angular position is to be sensed. The first and second coupling means respectively define axes of permitted angular movement of the first and second fixing means with respect to the link member and are associated with angle sensing means (21, 23 and 51, 53) providing electrical outputs representative of the angular positions of the fixing means about these axes. The sensor further includes a third coupling means (29, 31, 33 or 57, 59) whereby the fixing means may be moved translationally with respect to one another without altering any of the outputs of the angle sensing means.

Abstract: A system for collecting dust during drilling operations in a mine with a roof drill machine is described herein. The system consists of a mobile roof drilling machine having a conical shaped dust-collecting bowl adjacent to the surface being drilled. It is provided with annular space between the drill and the conical dust-collecting system to allow the drill to be injected into the roof of the mine. The system has a strong suction mechanism tangentially associated on each side of the dust-collecting system so as to provide a swirling motion of the falling dust particles.
