The present invention provides an electrode band, an electrode structure, a feed line, and an electrical impedance imaging device. The electrode band comprises: a band (1) which is elastic and is provided with a first surface (11) and a second surface (12) which are oppositely disposed; and a plurality of electrodes (4) fixed on the first surface (11) and provided with male buckles (43) which penetrate through the band (1) and are exposed on the second surface (12), the male buckles (43) being electrically connected to the electrodes (4). The electrode band of the present invention is simple in structure and low in cost, and can rapidly and conveniently fix the electrodes to the body of an object to be measured, and the fixing efficiency is high; the electrode band is elastic, and when the electrode band is fixed around the thoracic cavity of the measured object, the elastic force of the band is converted into pressing force on the electrodes, so that good contact between the electrodes and the skin of the thoracic cavity can be ensured; and the electrode band and the feed line are provided in a split mode by means of a male buckle-female buckle structure, so that the design of the electrode band is simplified, the feed line can be repeatedly used, and the replacement cost of the electrode band is reduced.

A retainer apparatus including a first retainer portion, a second retainer portion, a wireless transceiver, and a sensor contained within at least one of the first retainer portion and the second retainer portion. The retainer apparatus includes the first retainer portion configured to be slidably attached to a first harness strap and a second retainer portion configured to be slidably attached to a second harness strap. The first retainer portion is removably attached to the second retainer portion. The sensor is configured to detect the first retainer portion being disconnected from the second retainer portion and generate a warning signal. The wireless transceiver is configured to wirelessly transmit the warning signal to a controller in a vehicle to activate an audible warning alert to warn a user in the vehicle of the first retainer portion being disconnected from the second retainer portion.

The invention relates to a jewelry clasp, comprising two fastening parts, which each have, among other things, a permanent magnet. The invention further relates to the use of such a jewelry clasp as a safety closure and/or fastening system, to bracelet comprising such a jewelry clasp, and to a kit comprising at least two bracelets.

A retainer apparatus including a first retainer portion, a second retainer portion, a wireless transceiver, and a sensor. The sensor includes a first sensor portion physically contained within the first retainer portion and a second sensor portion physically contained within the second retainer portion. The first retainer portion is removably attached to the second retainer portion. The sensor is configured to detect the first retainer portion being disconnected from the second retainer portion and generate a warning signal. The wireless transceiver is configured to wirelessly transmit the warning signal to a controller in a vehicle to activate an audible warning alert to warn a user in the vehicle of the first retainer portion being disconnected from the second retainer portion.

The present invention relates to a device for connecting straps, objects or portions of garments and accessories forming a quick-snap buckle. The device according to the invention comprises, in accordance with a first feature, two strictly identical and complementary parts, such that said parts may be combined to thus form a single assembly. To achieve said assembly, said parts have a main body provided with two or three parallel lobes (2-5) that are flat and curved portions that fit into one another, wherein said lobes have circular movable members that bend in order to lock the device, for the male portion of said members, and circular movable members that bend and are equivalent to push buttons (6) to release the device, for the female portion of said members. The architecture and the mode of connection of the parts make it possible to assemble not just two parts, but also three, four, five parts or more, and simultaneously make it possible to work with special functionalities or specific strap shapes.

A fixing belt which includes: a double-sided hook surface fastener having hook-like engaging elements on both surfaces thereof; and a double-sided loop surface fastener having loop-like engaging elements on both surfaces thereof. The double-sided hook surface fastener is an extrusion molding surface fastener, the double-sided hook surface fastener is folded back in a length direction in a shape of an alligator's mouth, and the double-sided hook surface fastener is fixed to a first mounting object at a folded-back portion by a rivet. One end portion of the double-sided loop surface fastener is tucked by the alligator's mouth, the double-sided loop surface fastener is folded back by an annular part fixed to a second mounting object, and the other end portion of the double-sided loop surface fastener engages with an outer side surface of the alligator's mouth.

A retainer apparatus including a first retainer portion, a second retainer portion, a wireless transceiver, and a sensor contained within at least one of the first retainer portion and the second retainer portion. The retainer apparatus includes the first retainer portion configured to be slidably attached to a first harness strap and a second retainer portion configured to be slidably attached to a second harness strap. The first retainer portion is removably attached to the second retainer portion. The sensor is configured to detect the first retainer portion being disconnected from the second retainer portion and generate a warning signal. The wireless transceiver is configured to wirelessly transmit the warning signal to a controller in a vehicle to activate an audible warning alert to warn a user in the vehicle of the first retainer portion being disconnected from the second retainer portion.

A locking buckle comprising a first buckle member and a second buckle member. The first buckle member may comprise a first strap-receiving slot for receiving a first loop end of a strap, the first strap-receiving slot is defined in part by a strap-retaining bar and a body of the first buckle member and a strap-locking bar pivotably attached to the body of the first buckle member, the strap-locking bar pivotable between an unlocked configuration in which a strap may freely pass through the first strap-receiving slot and a locked configuration in which a strap passing through strap-receiving slot is prevented from passing freely through the first strap-receiving slot. The second buckle member is connectable to the first buckle member. The second buckle member comprises a second strap-receiving slot for receiving a second loop end of the strap.

A buckle includes two coupling modules coupled separably to each other. Each of the coupling modules includes a main unit including a hook member and a coupling member that has a retaining portion, and an operating member having an operating portion and a pushing portion. The hook member of each of the coupling modules is engaged with the retaining portion of the other one of the coupling modules. The operating portions of the operating members of the coupling modules are movable toward each other, during which the pushing portion of each of the coupling modules pushes the hook member of the other one of the coupling modules to disengage said hook member from the retaining portion of the coupling module.
