A tangless buckle system for straps for watches, fitness monitors, and other limb-worn devices. In such tangless buckle systems, a buckle with a tooth is provided. In contrast to a traditional buckle, the tooth and the buckle are fixed with respect to one another, i.e., the tooth does not rotate relative to the buckle. As this new buckle design does not include the rotating tang that extends all the way across the buckle loop in a traditional buckle design, the new design may be referred to as a tangless buckle. Such buckles may provide a simpler, yet highly secure, mechanism for securing such devices.

Provided is an electronic lock for wearable electronics, the electronic lock including: a button assembly; a spring assembly coupled to the button assembly, the spring assembly comprising: two bent arms configured to compress under a force applied to the button assembly; and an aperture configured to receive a stopping element when the locking mechanism is in a locked position; an actuator configured to electronically control movement of the stopping element in and out of the aperture; and a control circuit comprising: a tangible non-transitory machine readable media storing instructions that when executed by one or more processors of the control unit effectuate operations comprising: receiving a request to unlock the locking mechanism; sending a request for authentication; receiving authentication information; and controlling the actuator to move the stopping element from the locked position.

Waistbands and wristbands include separable clasps suitable to join woven Paracord around a user's waist or wrist. Matching clasp pieces are attached to opposite ends of single lengths of woven Paracord and magnetically snap together and hold firm until twisted by the user or pulled apart by excess hauling force applied to the woven Paracord. Side slippage between matching magnetic plates of the clasps are textured with indentations and matching protrusions to control such slipping. In particular, such indentations and matching protrusions are concave and convex oval cones of matching height and base. These cones impart a ramping leverage effect that translates lateral movements into separating forces that both assist a user in dismounting the clasp by twisting and in the predicable and controllable release of the clasp subjected to longitudinal single-vector excess hauling force.

A metallic mesh material used to form a portion of a band or securing strap for a wearable electronic device. The band may include a magnetic tab for securing a wearable device to the wrist of a user. The tab may include one or magnetic elements that are configured to engage a surface of the mesh to secure the wearable device to the wrist of a user.

A wearable smart device have a display, a body configured to support the display by having a prescribed curvature to be worn on a user body of a user, a band configured to be detachably coupled with the body by having a prescribed curvature, a first connector configured to couple a first end portion of the band to the body, the first connector configured to separate the first end portion of the band from the body, and a second connector configured to couple a second end portion of the band opposing the first end portion to the body, the second connector configured to separate the second end portion of the band opposing the first end portion from the body. A first direction for separating the band from the body in the first connector is different from a second direction for separating the band from the body in the second connector.

Systems and methods for dynamically adjusting the fit of a wearable electronic device are disclosed. In many embodiments, a tensioner associated with a wearable electronic device can control one or more actuators that are mechanically coupled to either the housing or to a band attached to the wearable electronic device. In one example, in response to a signal to increase the tightness of the band, the tensioner can cause the actuator(s) to increase the tension within the band.

A wearable device and a method for controlling the same, the wearable device including: a device main body and a wearing part for having the device main body worn on a human body, and the device main body is provided with a micro-controlling unit for controlling operation of the wearable device; and the wearing part is provided with one or more linear motors, each of the linear motors is connected to the micro-controlling unit by a controlling wire, and when the linear motor receives a specified signal of the micro-controlling unit, the linear motor correspondingly vibrates. The wearable device provides one or more linear motors on the wearing part, and controls the linear motors to, upon receiving the specified signal, vibrate, thereby providing the user with a solution of portable vibration tactile feedback and enhancing the user usage experience of the wearable device.

Watch comprising a watchband fixed to a case, this watchband comprising an extending strand, and a buckle arranged to encircle a case or an element protruding from this watchband, formed by this extending strand or by an added buckle, and the buckle comprises a stop surface arranged to cooperate, in a fastened position, either with a first complementary stop surface of a case, or with a second complementary stop surface comprised in the protruding element of the watchband.

A magnetic clasp system includes a first clasp component and a second clasp component, each containing a magnet and multiple holes for threading materials through. Multiple magnets can be implemented in the first clasp, and be configured to attract multiple magnets in the second clasp to secure the first and second clasps together. The clasp system can be used to securely connect articles such as jewelry, clothing, and hair accessories.

The invention relating to a locking mechanism is provided herein. The invention is composed of a pin adapted with a circumferential pin notch; a lock housing; a chamber with a chamber pin slot for receiving the pin and adapted to mate with the lock housing; a set of a given number of uniformly dimensioned ball bearings; a bearing housing adapted to fit inside the chamber, adapted to contain the ball bearings while enabling horizontal movement of the ball bearings and restraining vertical movement of the ball bearings, and adapted with a bearing housing pin slot for receiving the pin. When the pin is inserted into the chamber pin slot, the pin applies horizontal force to the ball bearings, which in turn deform the inside of the chamber. The ball bearings seat in the circumferential pin notch, locking the pin in place.
