A tripod system including clamp assembly, rod assembly, rod-hub, plurality of spoke-rods, plurality of corner-joints, plurality of screen-rods, plurality of storage-assembly-rods, plurality of storage assembly rods, and plurality storage assembly corners. Each of spoke-rods and screen-rods are adjustable in length. The tripod system configured to hold and maintain a screen. The clamp assembly is removably affixable to a tripod. The rod assembly includes first-end and a second-end, with rod assembly removably affixable to clamp assembly at first-end in a substantially horizontal plane. The rod-hub includes plurality of spoke-apertures, with the rod-hub affixable to second-end of the rod assembly and rotatable in relation to rod assembly. The plurality of spoke-rods insertable into the plurality of spoke-apertures of the rod-hub and the plurality of corner-joints removably affixable to the spoke-rods where the plurality of screen-rods removably affixable between two corner-joints.

The card forming a support for a valuable object, particularly a small precious metal ingot incorporated in said card, includes a core with a through aperture in which said valuable object is arranged, said through aperture having larger dimensions than those defined by the contour of said valuable object in the main geometric plane of said card. This valuable object is located in a central area of the through aperture so that a transparent peripheral area surrounds the valuable object inside said through aperture. The valuable object is embedded in a transparent resin which entirely fills the area peripheral to said valuable object between said object and the contour of the through aperture, so that the space remaining in the aperture around the valuable object is entirely filled by the resin.

A display apparatus includes a substrate including a first area, a second area, and a bending area, the bending area disposed between the first area and the second area and bending about a bending axis running along a first direction; a first piezoelectric device disposed over the bending area; and a pressure sensor. The first piezoelectric device is configured to contract or expand according to a pressure variation sensed by the pressure sensor.

A portable temporary road sign structure comprises a sheet material substrate cut into a flat pattern having three interconnected panels: a display panel; a base panel; and a brace panel. The panels are formed to enable deployment into a self-supporting configuration in which the display panel is held upright when the base panel is placed on the ground. For transportation between sites the base and brace panels can be folded flat against the display panel whereby respective handle align for ease of carrying. Various apertures and formations are provided to enable the road sign structure to be held in place, when deployed, by roadside fixtures or weighted bollards.

A paint composition includes a fluid and a coloring agent in the fluid. The fluid maintains the coloring agent in a first protonation state. The coloring agent exhibits a first color characteristic in the first protonation state. The paint composition includes microcapsules in the fluid. The paint composition also includes a chemical compound in the microcapsules. Rupture of at least a portion of the microcapsules is configured to release the chemical compound and expose the coloring agent to the chemical compound. Exposure of the coloring agent to the chemical compound changes the coloring agent from the first protonation state with the first color characteristic to a second protonation state with a second color characteristic. The second color characteristic is visually distinct from the first color characteristic.

A label includes a timer to monitor a predetermined time period relating to a medical device, such as an indwelling cannula, or other product. The label includes a signalling apparatus that provides an alert signal on expiry of the predetermined time period and a fixing portion to fix the label to a support surface such as medical records of a patient. The label can have a first portion and a second portion and the first portion can be separable from the second portion. The fixing portion can be provided in the second portion and all or part of the signalling apparatus provided in the first portion. Also disclosed is a monitoring system for a medical device, including a base station and a label receivable by the base station. The monitoring system monitors a predetermined time period based on receipt of the label by the base station.
