Methods for metabolic oligosaccharide engineering that incorporates derivatized alkyne-bearing sugar analogs as “tags” into cellular glycoconjugates are disclosed. Alkynyl derivatized Fuc and alkynyl derivatized ManNAc sugars are incorporated into cellular glycoconjugates. Chemical probes comprising an azide group and a visual or fluorogenic probe and used to label alkyne-derivatized sugar-tagged glycoconjugates are disclosed. Chemical probes bind covalently to the alkynyl group by Cu(I)-catalyzed [3+2] azide-alkyne cycloaddition and are visualized at the cell surface, intracellularly, or in a cellular extract. The labeled glycoconjugate is capable of detection by flow cytometry, SDS-PAGE, Western blot, ELISA, confocal microscopy, and mass spectrometry.

A particular apparatus includes a first electronic component, a second electronic component, and a connecting element that is detachably connectable to the first electronic component and to the second electronic component. The first electronic component is connectable via the connecting element to the second electronic component to form a wearable item. The first electronic component includes a camera, the second electronic component includes an energy storage component, and the first electronic component is configured to receive power from the second electronic component via the connecting element.

A stabilizing assembly for an optical device includes a base plate having a blade curved to fit against a person's torso, a strap extending outwardly from the base plate; a socket defined in the base plate and a mounting screw spaced from the socket. The blade extends below the base plate and an adjustment member is located on the underside of the base plate a distance from a lower end of the blade. The optical device is engageable with the stabilizing assembly in two ways. Firstly, the blade is inserted between the person's torso and a waistband or belt. The strap is passed around the person's neck and an end of a monopod engaged with the optical device is inserted into the socket. Secondly, the optical device is directly engaged with the mounting screw and the assembly is placed on the ground supported by the blade and adjustment member.

Methods and apparatuses are disclosed for fabricating an electronic device with an integrated railing system that detachably couples mounting hardware to the electronic device. By selectively detaching the mounting hardware, the electronic device may be made more compact and portable. In some embodiments, the railing system is fabricated substantially contemporaneous to fabricating the electronic device, such as by extrusion of the railing and the electronic device together. This fabrication approach may reduce the overall cost and complexity of manufacturing the railing system.

A mounting structure for a camera system includes a wearable portion; a base portion attached to the wearable portion; a mount portion; and a first fastener attaching the mount portion to the base portion, wherein a frictional force between the base portion and the mount portion controls a rotation of the mount portion about an axis of the first fastener. The mounting structure further includes a second fastener attaching a camera to the mount portion.

A device incorporating both a magnet and a living hinge may be employed to construct cases to protect electronic devices and to function as a closure for cases and lidded containers. Such cases often can be bent three 360° allowing the cases to be either closed protecting devices therein are closed upon themselves allowing the case to function to secure an electronic device to a substrate such as an article of clothing. The devices of the disclosure can also be used to organize and hold loose items together.

Holding device (100) for portable equipment, in particular cameras, comprising a housing (1) in which a roller element (2) and a return element (7) are arranged, wherein the roller element (2) is arranged on the housing (1) and is rotatably mounted in relation to the housing (1), a tie (9) for fastening equipment items, wherein the tie (9) is completely rolled up on the roller element (2) in an initial state and only one end of the tie (9) protrudes from the housing (1), wherein the return element (7) is arranged between the housing (1) and the roller element (2) in such a way that the return element (7) exerts a tensile force on the roller element (2) so that the tie (9) can be rolled up on the roller element (2), wherein the tie (9) can be unrolled and can be pulled out of the housing (1) in relation thereto when a tensile force facing away from the housing (1) is exerted on the tie (9), a force which is greater than the force exerted by the return element (7) on the roller element (2), up to an end position in which the tie (9) is completely unrolled from the roller element (2), and wherein the tie (9) can be rolled up to the initial state and can be pulled out of the housing (1) in relation thereto when a tensile force facing away from the housing (1) is exerted on the tie (9), a force which is smaller than the force exerted by the return element (7) on the roller element (2),
where
the holding device (100) comprises a bistable locking mechanism (20) with two switching positions, namely a locked position and an unlocked position, wherein in the locked position the rotation of the roller element (2) in relation to the housing (1) is blocked and the tie (9) is rolled off by at least 80%, in particular by 80 to 99%, preferably by 95 to 99%, wherein in the unlocked position the roller element (2) is rotatable in relation to the housing (1) and wherein the locking mechanism (20) can be changed between the locked position and the unlocked position by placing the tie (9) in the end position.

Attachment systems for releasably securing an accessory to an article, such as a helmet, are disclosed. In one embodiment, an attachment system (100) includes an attachment plate (102) that includes engaging features (108, 110) which engage corresponding engagement features on an attachment base (104). At least one of the engaging features (110) on the attachment plate is associated with a flexible member (112), and is movable between a locked configuration and an unlocked configuration via deformation of the flexible member. A pair of grips (114) are provided on opposing ends of the flexible member, and the grips are pressed toward one another to move the movable engaging feature between the locked and unlocked configurations.

A camera carrying system of the invention comprises a base attachment configured to be affixed to a bottom face of a camera, the base attachment including spatially-separated first and second bottom eyelets. A shoulder strap having first and second strap ends is connected to the first and second bottom eyelets and creates first and second tether points. The tether points define a rotation axis lying substantially parallel to the bottom face of the camera, substantially parallel to a rear face of the camera, and beneath a center-of-mass of the camera. A tripod adapter may be integrally formed in the base attachment so the camera can be readily mountable to a tripod once disconnected from the base attachment. A method is provided for stabilizing the carrying of a camera by a shoulder strap. The method comprises use of the camera carrying system.
