Abstract: A head-mounted device may include a main housing portion and displays in the main housing portion that provide images to eye boxes. A light seal may be coupled to the main housing portion and may at least partially surround the eye boxes. The head-mounted device may include sweat mitigation structures such as moisture-guiding channels in the light seal to guide sweat and other moisture away from the eye boxes. The moisture-guiding channels may be formed from grooves or moisture-wicking fabric. Control circuitry may adjust a fan based on humidity, temperature, or fog detected by a sensor. The light seal may include a directional pattern of grooves through which moisture is guided away from the eye boxes. A moisture barrier layer may be interposed between an inner foam layer and an outer light-blocking fabric to prevent sweat from penetrating into the foam.

Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

Abstract: Components for reducing oil sticking on surfaces of an internal combustion engine are disclosed. The engine may include an engine block with a piston cylinder, a piston moveable in reciprocal motion within the piston cylinder, and a cylinder head mounted on the engine block. The engine block, the cylinder head, and the piston may define a combustion chamber. The engine may include an intake conduit mounted to the cylinder head, an intake valve port defined by the cylinder head, and an intake valve mounted in reciprocally movable fashion to the cylinder head for placing the intake valve port in fluid communication with the combustion chamber. The engine may include a first oleophobic coating provided on portions of the intake valve, and a valve seat insert secured to the cylinder head. The valve seat insert may define an oil passage in fluid communication with the intake valve port.

Abstract: A canteen for use on picnics and other outings and which is capable of holding a first drink, such as water, lemonade, frozen daiquiris, etc., and which includes a cover through which the first drink may be consumed through a tubular straw member. A capsule is provided for holding a second drink; the capsule being removably held in a bracket formed on the underside of the cover, with the capsule extending down into the drink in the canteen. The capsule is previously placed in a freezer in order to freeze the second drink, so that the second drink may serve to cool the first drink during the outing. The capsule may subsequently be removed and the cool, melted second drink may be drunk through a neck formed in the upper end of the capsule.

Abstract: A holder for a frozen confection, such as an ice cream stick, or the like, which serves to hold the frozen confection in an upright position. The holder includes a trough-like upper dish which is slotted to maintain the stick of the frozen confection in an upright position, and which is shaped to catch any drips from the frozen confection as it melts. The dish fits into the open end of a cylindrical base, and it is apertured so that the collected drips from the frozen confection flow into a reservoir which is formed in the upper end of the base. The drips are accumulated in the reservoir to produce a liquid. An upwardly inclined tubular member is fitted into the side of the base and extends into the reservoir to form a drinking straw. An intermediate circular handle is formed in the tubular member.

Abstract: A canteen including a cylindrical container and a head threaded to the open top of the container, and also having a flip-up cap pivotally mounted on the head. A push-button is provided at the side of the head which, when actuated, flips up the cap to an pen position, and also pushes a spring-biased plunger away from the drinking hole to open the drinking hole. When the push-button is released, the spring-biased plunger moves to close the drinking hole. Accordingly, by operating a single push-button, the user causes the cap to flip up to an open position, and also causes the drinking hole to open, the drinking hole remaining open so long as the push-button is held by the operator in its actuated position.

Abstract: Multiple containers are provided for carrying the same or different types of food independently of one another, and which may be securely locked to one another in a compact stack for ease of carrying. The upper container is provided with a channel for receiving a utensil receptacle in a snap-fit relationship, and a utensil in the form, for example, of a plastic spoon-shaped fork is pivotally mounted to the receptacle to be turned to extend along the underside of the receptacle when the receptacle is mounted in place on the cover of the upper container, and which may be turned to extend out of the end of the receptacle when the utensil is to be used.

Abstract: A mesh bag is provided for toys, laundry and beach use, and the like, which is formed of a tubular lower portion of a mesh material, and which has an open top, a closed bottom, and overlapping sides which form a side opening. A solid fabric upper portion of the bag is secured to the lower portion and surrounds the open top of the lower portion. The solid fabric upper portion extends across the top of the overlapping sides to assist in holding the side opening in a closed condition. A plastic tube is sewn to the upper rim of the upper portion, and it serves to flatten out the sides of the upper rim and hold the top of the bag closed. A pair of upwardly-extending loop handles are attached to the upper portion on opposite sides of the bag.

Abstract: A novelty elongated handle for a child's spoon, fork or the like, which is formed of a rigid, transparent plastic material, such as acrylic. The handle is hollow to provide a transparent sealed chamber which is filled with a transparent liquid, such as water. A multiplicity of glittering particles are suspended in the liquid and float about in the liquid. The handle is constructed firmly to support the spoon, fork, or the like, at its forward end in isolated relationship from the chamber. The rear end of the handle is opened to permit the introduction of the liquid and glittering particles into the chamber. A resilient stopper is inserted into the open end of the handle and it, in turn, is covered by a plastic cap which is sealed to the rear end of the handle.
