The invention discloses several types of fastener, fastening systems, fastener assemblies and related areas.

In particular, the invention relates to a releasable fastening system (50) which has a pin (152) with a locking cavity (163). The pin is intended for insertion in an aperture (154). A locking means (158, 160) engages the locking cavity (163) of the pin (152) when the pin (152) is received in the aperture (154). The system (150) also includes unlocking means (162) which includes material adapted to contract when activated. When a material contracts, engagement means (158) included in the locking means (158, 160), disengage the locking cavity (154).

A releasable restraint may comprise a base and a socket coupled to the base. The socket may include a head and a shaft extending from the head. A sleeve may be configured to translate relative to the shaft of the socket. A plurality of balls may be located in the shaft of the socket. A plug may be received by a plug groove defined by the socket.

A system, comprises an implant including an outer sleeve and a head element, the outer sleeve extending longitudinally and including a channel extending therethrough, the head element including a shaft portion and a bone-engaging portion, the shaft portion received within the channel of the outer sleeve and longitudinally movable relative thereto and a clip device removably assembled with the implant to hold the outer sleeve and the head element in a desired position relative to one another, the clip device including a body extending longitudinally along with a separation portion connected to a proximal end of the body via a releasable connection to engage the proximal end of the outer sleeve and a spacer portion connected to the proximal end of the body to releasably engage a portion of the shaft portion between a proximal end of the bone-engaging portion and the distal end of the outer sleeve.

A vehicle includes an engine compartment and two rockers fixed relative to the engine compartment. The two rockers define a passenger cabin. A first water sensor is disposed in the engine compartment, and second and third water sensors are disposed in the passenger cabin at the rockers. A seatbelt buckle is disposed in the passenger cabin and has an actuator. A control module is in communication with the water sensors and the actuator. The control module is programmed to actuate the actuator based on signals from the water sensors.

The socket may include a head and a shaft extending from the head, wherein the shaft defines a base channel configured to receive the base. A sleeve may be configured to translate relative to the shaft of the socket. A plurality of balls may be located in a plurality of frustoconical ball openings formed through the shaft of the socket. A plug may be received by a plug channel defined by the socket.

A strap adjusting device and a wearable device are provided. The strap adjusting device is configured for adjusting a length of a strap of the wearable device and includes a pressing piece including a supporting plate connected to the strap and a cushion arranged on the supporting plate; a first sensor arranged on the pressing piece and configured to detect a deformation parameter value of the cushion; and a tightness adjusting mechanism cooperating with the strap and configured to adjust the length of the strap in response to the deformation parameter value of the cushion.
