A suction-security system includes an adhesion membrane coupled to a swing arm. Rotation of the swing arm lifts a center portion of the adhesion membrane, creating suction and adhesion of the suction-security system to an anchor surface. The swing arm may have a low profile enabling use of the suction security system in an enclosure with minimal loss of available interior space. The system may include a shield protecting the adhesion membrane, and a bushing in the shield permits rotation of a portion of the shield without disturbing adhesion of the adhesion membrane to the anchor surface. The suction-security system may be used in consumer items such as purses, backpacks, briefcases, and suitcases.

A viewing apparatus that is securable (lockable) to surfaces includes a mirror, a base, and an interconnection assembly between the base and the mirror. The base includes a suction device for selectively locking or unlocking the viewing apparatus to/from a mounting surface. The suction device utilizes a lifter and an internal coupler that drives the lifter, responsive to user operation of a lock/unlock selector, to reposition a flexible diaphragm increasing or decreasing the volume of a space between an underside surface of the suction device and the mounting surface depending upon a direction of rotation of the selector.

A radar level gauging arrangement for performing radar level gauging in a tank having a tank wall which is impermeable to a product held in the tank and transmissive to radar signals, comprising an attachment device configured to be secured to a substantially flat portion of said tank wall, without penetration of the tank wall, and a radar level gauge including a directional antenna, the radar level gauge being mounted to the attachment device, such that, when said attachment device is secured against the tank wall, the directional antenna is positioned so as to enable transmission of radar signals through the tank wall. By mounting a radar level gauge to an attachment device which can be secured to the tank wall without penetrating the tank wall, radar level gauging can thus be provided without damaging or interfering with the tank.

A suction foot for a device or appliance has a side wall in which is formed a notch. The notch begins at a lower most rim of the foot.

A surface mount is provided having a body, a lever, a laterally offset connector, and a diaphragm. The surface mount may be mounted to a surface at the diaphragm and support an object via the connector.

The pressure balancing device comprises a housing, a deformation medium accommodated in the housing and capable of deforming under compression, and a sealing member movably connected with the housing and capable of deforming under pressure. When part of the deformation medium is compressed by the sealing member, the deformation medium deforms so that a part, not compressed, of the deformation medium compresses a corresponding part of the sealing member to make it protrude outwards. The pressure balancing device is simple in structure, easy to assemble and convenient to operate, and raw material cost and processing cost are saved a lot.

A mount includes a frame, a head coupled to a first end of the frame, a suction cup positioned at an opposite second end of the frame, and a suction-cup activator. Rotational movement of the suction-cup activator causes a corresponding axial moment of the suction cup for attaching the mount to a surface. The head allows attachment of a handheld electronic device to the mount.

A suction holder includes a suction unit, a housing unit, a pressure deformable unit, and a linkage positioning unit. The suction unit includes a suction cup and a traction element engaged to a top of the suction cup. The pressure deformable unit has a circumference radially distributed with a plurality of elastic pressing elements. The pressure deformable unit is located on the suction cup and is confined in the housing unit. The linkage positioning unit can drive the traction element to move upward so that the suction cup can attach to a surface. When the surface is curved or has arcs, the elastic pressing elements can be deformed to different extents to be pressed on the suction cup to maintain better attachment to the surface.

A touch display device includes a display module, a touch module and a light-transmitting substrate. The display module has a display surface and a bottom surface opposite to the display surface. The touch module is fixed to the display surface by an adhesive. The adhesive, the touch module and the display surface together form an accommodating space between the display module and the touch module. The light-transmitting substrate is disposed in the accommodating space, one side of the light-transmitting substrate is fixed to the display surface by a first optical adhesive, the other side of the light-transmitting substrate is fixed to the touch module by a second optical adhesive. An adhesive strength of the adhesive is greater than an adhesive strength of the first optical adhesive, and the adhesive strength of the adhesive is greater than an adhesive strength of the second optical adhesive.
