A connector with two magnets with like poles facing towards each other. A first magnet of the two magnets is fixedly attached to a support base and female receptacle situated above the same pole of the first magnet. The second magnet is fixedly attached to a male flange adapted for passage through the female receptacle. The male flange and second magnet are further fixedly attached to a length of material which is longer than the female receptacle, such that the male flange remains within the female receptacle in an assembled condition due to a magnetic force pushing each magnet away from the other. Another embodiment includes a method of use, including lining up the male flange into the female receptacle for locking and pushing down and slightly transversely on the male flange to unlock.

An aerosol generating device is provided. The aerosol generating device includes: a body providing an insertion space defining an opening; a heater; a battery configured to supply power to the heater; a controller configured to control the power supplied to the heater; a cap provided with a first magnet and configured to slide between a first position at which the opening of the insertion space is opened and a second position at which the opening is closed by the cap; and a second magnet fixed to the body to correspond to the first position.

An improved method and system for providing a magnetic closure system for an electronic device (100) may include a first portion (130), a second portion (150), a connecting element (145) pivotally connecting the first portion to the second portion and configured to enable the electronic device to fold between a closed position and an open position, and a magnetic element (160, 165) for providing a closure force to bias the electronic device in the closed position. The magnetic element may include a first magnet pair and a second magnet pair, each of the first magnet pair and second magnet pair including a first magnet housed within the first portion and a second magnet housed within the second portion. The first magnet pair may provide an attractive magnetic force that biases the electronic device in the closed position, while the second magnet pair may provide a repelling magnetic force that partially counteracts the biasing from the attractive magnetic force as a gap between the first portion and the second portion decreases, and a pole size of the second magnet pair is smaller than a pole size of the first magnet pair.

Self-tethering eyeglasses that include a pair of distal portions located on the terminal end of the temples of the eyeglasses, wherein the pair of distal portions each include a permanent magnet coupled thereto or formed thereon and are attached to a flexible cable that is freely disposed and movable within an internal channel formed within the temples and include a flange member coupled thereto that restricts the cable from being removed from the temple. As such, a user may remove the distal portions of the temples and magnetically couple them together to secure the eyeglasses to the head or neck area of the user.

A magnetically-attracted quick connection device includes a female connecting head and a male connecting head; the male connecting head includes a male seat, a first magnet, limiting beads, a thrust ring, a spring and a male cover; the first magnet is installed at a front end of the male seat and inside the male seat, the thrust ring is installed at a rear end of the male seat, the limiting beads are located between the male seat and the thrust ring, the spring is installed between the thrust ring and the male cover, the female connecting head includes a female seat, a female magnet seat and a second magnet, and the second magnet attracts the first magnet to guide the male seat to be quickly inserted into a slot, which is beneficial to the rapid insertion of the male connecting head and the female connecting head without complete alignment.

Disclosed is a storage device, including a first protective shell and a second protective shell for enclosing a peripheral side of an object that needs to be stored, and a locking member and an auxiliary unlocking member. The auxiliary unlocking member is configured to move along a shell surface of the first protective shell or move inside and outside towards the first protective shell to resist a locking force of the locking member. The locking member which can meet the locking and unlocking requirements of two protective shells cooperated with the auxiliary unlocking member which can adjust the locking force or locking state between two protective shells to reduce the difficulty of unlocking two protective shells. Therefore, the storage device can be used to reasonably and effectively store and protect the earphone charging compartment, or other products that are small in size and have a smooth and rounded appearance.

A magnetic release mechanism for use with underwater fishing equipment includes a base plate having a slot for receiving a buckle, and a recess for receiving a release plate. A permanent magnet positioned proximate the recess generates a first magnetic field for magnetically coupling the release plate to the base plate. An electromagnetic coil positioned proximate the permanent magnet is configured to selectively generate a second magnetic field when energized. A magnetic field sensor is positioned proximate the recess. A controller is operatively coupled to the magnetic field sensor. The controller may be configured to monitor the magnetic field sensor to detect the presence of a third magnetic field and, in response to detecting the presence of a third magnetic field, output a signal indicating that the release plate is magnetically secured within the recess.

A closure device includes a first magnet and a housing with a second magnet positioned therein. The first magnet is configured to be position in a first object and the housing is configured to be positioned in a second object. The housing has a top end and at least one adjustment mechanism connected to the housing that moves the second magnet in at least one translational direction or at least one rotational direction relative to the top end of the housing. The movement of the second magnet relative to the top end of the housing adjusts the position or orientation of the second magnet relative to the first magnet to alter a magnetic force between the first magnet and the second magnet when the first magnet is positioned proximate the top end of the housing.

A magnetic suction type waist belt buckle that can be quickly clamped is provided; a first fitting surface is formed on a male buckle. The first fitting surface is provided with a first installation groove, and the first installation groove is provided with a first magnetic suction structure; one side of the first fitting surface is provided with a tilted male buckle limit side plate; a second fitting surface is formed on a female buckle; one side of the second fitting surface is provided with an inclined female buckle limit side plate. The second fitting surface is provided with a second installation groove, the second installation groove is provided with a second magnetic suction structure; a waist belt clamping part is provided at a tail end of the male buckle, and a waist belt cavity is formed between the waist belt clamping part and the male buckle.

A cover for a watercraft includes a cover body connectable to the watercraft, and a fastening system coupled to the cover body. The fastening system being operable to selectively apply tension to the cover body. At least one attachment feature is arranged at an underside of the cover body. The at least one attachment feature is engageable with a receiving feature of the watercraft to restrict movement of the cover relative to the watercraft when the cover is not tensioned.
