Recently, researchers at the University of Michigan published a smart contact lens manufacturing program that enables the wearer to have "infrared night vision" capabilities.
The researchers said that sandwiching graphene between two lenses creates a sensor that can capture both visible and infrared light. The sensor can be as sensitive as the CMOS silicon image sensor used in commercial digital cameras. Currently, the research team has made a prototype that is smaller than a fingernail, and in the future it may be embedded in the lens to provide night vision to people in need. Zhong Zhaohui of the University of Michigan, USA, said that if the device is combined with contact lenses or other wearable devices, it can expand the user's vision and provide night vision capabilities.
Graphene is the thinnest and hardest nanomaterial in the world. It is one million times thinner than paper and almost completely transparent. In addition, graphene is a promising candidate for ultra-wideband photodetectors. When exposed to photons, graphene turns into so-called “hot carriers†that absorb ultraviolet to far-infrared spectra. Scientists can measure, process, and convert this effect into images.
Hydraulic Mount:
widely used in the suspension is divided into three categories,like traditional suspension of pure rubber mount,or Rubber Absorber, as well as Hydraulic Mount or Hydraulic Suspension of better dynamic and static performance.
The shape of rubber parts is not restricted, the stiffness can be chosen freely in a certain range, with spatial spring characteristic, load can withstand multiple directions; using friction damping, can absorb vibration and impact energy is good; and easy to bond metal firmly together, greatly simplified and fixed the supporting structure, so that the overall quality of the suspension reduced; structure has the advantages of simple process, low cost, suitable for mass production; convenient use and maintenance. Because of these advantages, the rubber mounting has widely used in most of the cars.
Structure:
Pure rubber suspension consists of rubber bushing (or other sulfide pieces) and the bracket, and the hydraulic mount is apart from the main rubber spring, but also the internal filling the special liquid (usually ethylene glycol), the runner plate, decoupling piece, composed of cups and other parts to a certain structure.
Performance requirement:
(1) Good vibration isolation performance, soft requirement in vertical direction;
(2) Larger lateral rigidity and stability of supporting body;
(3) Good durability.
How to design and select good auto suspension:
In the structural design of body mounting device location settings, select the number of points of suspension, determine the characteristics of suspension form and elastic rubber pad, we should consider the following aspects:
(1) The vehicle structure stiffness distribution relationship between the frame and the body and the stiffness of the transfer;
(2) Frame and body assembly connection position accuracy;
(3) The stability of the vibration isolation effect and the exercise of the body;
(4) The frame vibration and vibration;
(5) Suspension rubber pad device in the stress condition and durability;
(6) Stress of the frame.
