A vehicle having a hidden storage compartment with a user notification system and method of using the same is provided. The vehicle includes a storage container securely fixed onto an interior surface of a vehicle floor panel in the footwell area. A floor covering is disposed over the footwell area covering the storage container and includes a flap having a living hinge configured to selectively cover and uncover the lid of the storage container. The storage container includes a biometric scanner, a mass sensor, and a lid sensor in communication with a notification controller. The notification controller analyzes the information received from the biometric scanner, lid sensor, and mass sensor, and determines the state of the storage container based on a logic table. The notification controller then selectively transmit a predetermined message to the user based on the state of the storage container.

Provided is a fixed type constant velocity universal joint, in which: each of first track groove portions positioned on an interior side of an outer joint member includes an arc part having a curvature center that is positioned without being offset in an axial direction with respect to a joint center; the first track groove portions are inclined in a peripheral direction with respect to a joint axial line (N-N) and adjacent to each other in the peripheral direction with their inclination directions opposite to each other; each of second track groove portions positioned on an opening side is formed into a different shape from a shape of the each of the first track groove portions so as to increase an effective track length at a maximum operating angle; the each of the first track groove portions and the each of the second track groove portions are connected to each other at a position on the opening side with respect to the joint center; each of track grooves of an inner joint member is formed so as to be mirror-image symmetrical with corresponding one of paired track grooves of the outer joint member with respect to a plane including the joint center and being perpendicular to the joint axial line at an operating angle of 0°; and an axial clearance between the inner joint member and a cage is set to be larger than an axial clearance corresponding to a clearance between each of balls and each of the track grooves.

The invention aims to provide a waterproof moisture-permeable underwear and a waterproof moisture-permeable liner. By the waterproof moisture-permeable underwear, the degree of freedom in selecting a material can be increased, the waterproofness in junction areas can be improved, and staining of an outerwear with urine or menstrual blood leaked from an innerwear can be surely prevented. Specifically disclosed is a waterproof moisture-permeable underwear, which is to be put between an innerwear and an outerwear on the lower body, being constructed by bonding a plurality of two-layered fabric pieces (A), each comprising a base fabric (B) positioned in the innerwear side and a waterproof moisture-permeable membrane (C) laminated in the outerwear side of the base fabric (B), at junction areas, wherein, for the base fabric (B), a material superior in texture to the membrane (C) is selected; for the membrane (C), a material superior in welding properties to the base fabric (B) is selected; and the junction areas (21A-21F) are formed by welding.

The present invention discloses a sound wave filtering structure. The sound wave filtering structure comprises a cavity wall, a cavity cover and a slit. The cavity cover is mounted on the cavity wall. The cavity wall and the cavity cover are combined to form an inner cavity. The slit is formed on the cavity wall and / or the cavity cover. The cavity wall and the cavity cover seal the inner cavity. A space in the inner cavity is communicated with the outside only through the slit. On the other hand, the present invention further provides a side sound generating speaker module. The side sound generating speaker module at least comprises a side sound generating cavity and the above-described sound wave filtering structure. The side sound generating cavity is configured to guide sound waves to be transmitted from a side surface of a single speaker body. The sound wave filtering structure is arranged on the side sound generating cavity. The slit faces the interior of the side sound generating cavity. The sound wave filtering structure provided by the present invention can adjust and filter high-frequency sound waves. Especially, in the side sound generating speaker module, the sound wave filtering structure can significantly improve the sound quality of the high-frequency sound waves.

The invention relates to an electric dust cleaner with high adsorb property and sound adsorb property, which comprises: an electric fan for generating adsorb wind with an exhaust outlet; an electric fan room that at least partly covering said electric fan; and a main body exhaust outlet for discharging the discharge wind from the electric fan room to the air; on the box, an outlet is arranged to discharge the discharge wind of electric fan outside the box, and a bypass wall is arranged to bypass the discharge wind of said outlet. The inventive electric dust cleaner can realize high adsorb efficiency, reduce noise and adsorb noise.
