The present disclosure discloses a modular large spherical tank internal detection device with a self-locking function, and belongs to the technical field of safety detection of large spherical tanks. The detection device includes a transmission group and a detection group. A movable pin is matched with the rotation of a second motor in an unconnected state, so that inner central shafts rotate to realize up-down movement of a detecting instrument in a vertical plane. The movable pin is matched with the rotation of a first motor in a connected state, so that the whole detection device rotates round a central axis of a large spherical tank to realize horizontal circumferential movement of the detecting instrument. All detection of a spherical surface inside the large spherical tank can be completed by combining two types of movement of the detecting instrument.

Embodiments include a point of sale system. The point of sale system includes a base, a stand coupled to the base, and a head unit coupled to the stand. The point of sale system further includes two outer hinge arms and an inner hinge arm that couple the head unit to the stand.

According to examples, an apparatus may include a sleeve and a ring rotatably coupled to the sleeve. The sleeve may extend between a body of an electronic device and a base, and may have a recess to accommodate a cable. The ring may extend across an opening of the recess in a locked position and may be positioned behind the recess in an open position.

Disclosed is an ultrasonic diagnostic apparatus including an improved actuator to compensate for a weight of an input/output device. The ultrasonic diagnostic apparatus includes a main body, an input/output device coupled to the main body and configured to receive information from a user or output information received from the main body, and a connection device to connect the main body and the input/output device, wherein the connection device includes a shaft having a shaft body, a link frame having a frame body and a shaft coupling portion extending from the frame body to be coupled with the shaft, and an actuator including a torsion spring having a first end supported by the shaft and a second end supported by the link frame, so as to compensate for a weight of the input/output device.

An oblong cantilevered support includes a pair of latitudinally spaced apart oblong resilient members connected by a pair of longitudinally spaced apart blocks. The longitudinal spacing between the blocks can be adjusted. One or both of the members can have a tapered profile causing the stiffness of the member to vary along its length. Adjusting the spacing between the blocks and/or sliding a variable stiffness member longitudinally with respect to the blocks can adjust the stiffness of the overall support. Each member can be made from a unitary piece of fiber composite material such as a carbon fiber infused polymer wherein the orientations of the fibers are varied to provide both bending and torsional strength and stiffness that varies along the length of the member. The tapered geometry can be formed by a pair of parallely spaced apart oblique trapezoidal truncated pyramids interconnected by a webbing strip.

An interactive information system includes a first frame, a second frame, and a first inter-frame cable. A first interactive module is arranged in the first frame and includes a first display module; a first touch input module; at least one first user input device; a first control module bridge board configured to transmit intra-frame electrical signals; a first interactive module bridge board configured to transmit inter-frame signals; and a first intra-frame cable. A control module is arranged in the second frame and includes a logic module configured to generate the first GUI and to perform function of the interactive information system based on user inputs. The first interactive module and the control module are electrically coupled via only the first inter-frame cable. Both the first frame and the second frame contain an electro-magnetic (EM) shielding material.

A medical device suspension system includes a spindle extending along a longitudinal axis and a cable management cover surrounding the spindle. A gap is formed between the cable management cover and the spindle. A hub is rotatably mounted to the spindle and includes a housing. A top hub cover is disposed along the longitudinal axis between the hub and the cable management cover and defines an end of the gap, the top hub cover including a passage in fluid communication with an internal volume of the housing. The top hub cover is rotatable with respect to the spindle about the longitudinal axis. A cable is provided within the gap, the cable entering the gap at a fixed location about the longitudinal axis and passing into the housing through the passage. Rotation of the top hub cover about the longitudinal axis causes the passage to rotate about the longitudinal axis.

Systems and methods for assembling structural components are disclosed wherein a selectively configurable fixture is placed on an assembly surface of an assembly table. An assembly table interface couples about a pin of a pin slot of the assembly table and, by means of linkage assembly, translates movement of the pin to a positioning member. The positioning member, by the translated movement of the pin, abuts an element of structural component and supports the element while a fastener is applied to join multiple elements of the structural component. A selectively configurable fixture may be used in isolation, or in combination with other fixtures.

Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

A display device is disclosed. The display device includes a display panel, a back cover covering a rear surface of the display panel, a bracket coupled to a rear surface of the back cover, and a support removably coupled to the bracket, wherein the bracket includes a first plate, a second plate facing the first plate, and a link connecting the first plate to the second plate, wherein the second plate includes therein a slot, which is formed toward an inside from a lower side of the second plate and in which the support is movably received, wherein the link includes a lower link, and an upper link disposed above the lower link, and wherein each of the lower link and the upper link extends in a direction intersecting the first plate and the second plate, and is pivotably coupled both to the first plate and to the second plate.
