In a method for dust removal in a rollable display device, a control module activates rolling mechanisms and a dust removal mechanism of the rollable display device. The control module determines a first amount of dust particles on a display surface of the rollable display device using data from a dust detection mechanisms. When the first amount of dust particles is determined to exceed a threshold, the control module engages magnetic locks to lock the rolling mechanisms, and the dust removal mechanism continues to remove the dust from the display surface. The control module determines a second amount of dust particles on the display surface. When the second amount of dust particles is determined to fall below the threshold, the control module disengages the magnetic locks to release the rolling mechanisms. Dust removal mechanism may include piezoelectric strips or an ultrasound haptic effect generation module.

An anti-theft device for protecting a portable electronic device from theft or unauthorized removal in a retail environment is provided. A shroud may at least partially enclose a portable electronic device. A dock may releasably engage the shroud such that the shroud and portable electronic device are locked to the dock when engaged with the dock. A key may engage activate a lock mechanism to release the shroud and the portable electronic device from the dock.

An information handling system display swivel arm rotates about two axes with selectable amounts of rotation. The swivel arm couples to an anchor and a display support with a tool-less swivel coupling device having a member inserted into a housing and rotationally coupled in place by first and second pins that engage first and second slots of the member. The first slot is disposed around the circumference of the member to support substantially 360 degrees of rotation of the member in the housing. The second slot is disposed only part of the way around the circumference of the member to support partial rotation, such as 180 degrees. Removal of both pins from the member allows withdrawal of the member from the housing to disassemble the swivel arm.

The invention relates to a jaw grip mount equipped with theft protection for smartphones or tablets comprising: a body which forms a support surface for the smartphone or tablet; two jaws designed to grip the smartphone or tablet at two opposite edge regions and to receive the edge region in an interlocking manner, at least one jaw movable between an open position and a variable locking position and can be locked in the locking position; and a release button for unlocking the lock on the moving jaw in the closed position thereof. The invention further provides at least one actuating mechanism which can be moved between a plurality of defined and marked positions and which includes a key element which can interact only in a specific position with a complementary key element of the release button so that it is only possible to actuate the release button in this position.

Embodiments disclosed herein are directed to apparatus and methods for automatic fluid flow system connectors. The system generally includes a load cell interface coupled to a console and a ring connector coupled to a fluid collection system. The ring connector can be releasably engaged with the load cell using a push-button actuated locking mechanism. Embodiments of the locking mechanism can include a latch and aperture engagement, a shelf and ledge engagement, or a track and channel engagement, or combinations thereof. The ring connector and load cell can include electrical contacts configured to engage along an axis that extends perpendicular to a surface on which the electrical contacts are disposed. This is believed to reduce wear on the electrical contacts, thereby extending the usable life of the system.

Tripod having a tripod head, a shaft, having telescopic shaft parts, attached to the tripod head via a locking mechanism, and at least three support legs mounted so as to be outwardly pivotably on the shaft. The support legs are connected to the tripod head via pulling members which can be wound up and unwound by a coil arranged rotatably on the tripod head and can be tensioned by a tensioning element. It is proposed that the coil is provided with a return spring acting in the winding direction of rotation of the coil, and a coupling mechanism is provided which can be transferred with an operating element from a rotation mode, in which the coil can be rotated in an unwinding direction of rotation and by the return spring in a winding direction of rotation, into a tensioning mode, in which the coil is locked with respect to the pulling members and the pulling members can be tensioned by the tensioning element.

Display panel frames configured and dimensioned to support display panels and also attach to adjacent display panel frames in a modular fashion to form a larger display assembly. In some examples, the display panel frames include one or more structural members configured to support a load on the frame, wherein the structural members also have at least one display panel mount for attaching a display panel to the frame. In some examples, the frames are configured to support display panels having mounting interface points conforming with a Video Electronics Standards Association (VESA) interface standard.

The present disclosure relates to a detachable quick connection apparatus for photographic equipment and a photographic equipment assembly. The apparatus comprises a locking means and a connection assembly, the locking means comprising a fixed seat provided with at least one through hole and a driving means rotatable relative to the fixed seat, at least one latching member being provided between the fixed seat and the driving means, the connection assembly is provided with an engagement slot which is engaged by the locking member, the locking means comprises a locking member provided in the driving means and a locking spring, the locking member comprises a locating member and a first elastic member which are mounted in the driving means, the locating member is at least partially engaged between the fixed seat and the driving means at the releasing position so that the driving means is stopped at the releasing position.

The present disclosure, pertaining to the technical field of tree skirt stands, relates to an I-shaped tree skirt stand including a plurality of tree skirt units that are engaged with each other. The tree skirt stand unit is formed of an upper connection bar, a lower connection bar, and a vertical fixation bar. Upper and lower ends of the vertical fixation bar are respectively fixedly connected to middle portions of the upper connection bar and the lower connection bar. The upper connection bar, the vertical fixation bar, and the lower connection bar are arranged in an I shape. The tree skirt stand is simple in assembling, the volume of the tree skirt stand in a disassembled state is reduced, and transportation and storage are eased.

Disclosed are adjustable supports and bedsteads. An adjustable support includes an inner bar with one or more cuts and an outer tubular bar with a slot. The inner and outer bars are movably coupled with each other. The adjustable support also includes a mechanism coupled with the outer bar at a position corresponding to the slot of the outer bar. When a cut of the inner bar is aligned with the slot of the outer bar, the mechanism engages with both the cut of the inner bar and the slot of the outer bar, and thus restricts the inner and outer bars from moving with respect to each other.
