Wind Resistance
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net aerodynamic or hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscous drag of fluid in a pipe: Drag force on the ...

Mmwave Sensing
Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it receives back. Additional components such as converters, signal processors and other embedded technologies create new use cases and improve performance of the system. Current applications for this technology include human and animal movement tracking, human presence detection, and detection of vital signs for use across automotive, meteorological, medical and pet health industries and is often an alternative to wearable-based technologies for the same uses. Compared to sensing technologies using other radio frequencies in the electromagnetic spectrum such as infrared or ultra-wideband, mmWave uses 30 to 300 gigahertz (GHz). Typical mmWave sens ...

Lidar
Lidar (, also LIDAR, an acronym of "light detection and ranging" or "laser imaging, detection, and ranging") is a method for determining ranging, ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. Lidar may operate in a fixed direction (e.g., vertical) or it may scan multiple directions, in a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications. It is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swathe mapping (ALSM), and Mars Orbiter Laser Altimeter, laser altimetry. It is used to make digital 3D modeling, 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has also been in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesai
Hesai Technology (Hesai; ) is a U.S.-publicly listed Chinese technology company that engages in the development and sales of lidar products such as sensors. Its products are used mainly in the ADAS, vehicular automation, robotics and industrial sectors. History When Hesai was founded, lidar products were entering a period of growth especially when American companies were launching robotaxis. At that time, a set of lidar products could cost up to US$80,000 however Hesai was able to sell them for US$40,000 which helped it to gain it market share. Hesai has seen domestic success in China. Previously Baidu acquired light sensors from Velodyne Lidar for its robotaxis. However Velodyne did not have a warehouse in China and it took months to send parts back and forth to the US for repair. Hesai took advantage by being able to provide domestic after-sales service that could repair components within two days. As a result, in 2018, Baidu awarded Hesai a contract to be its supplier. ...

Head-up Display
A head-up display, or heads-up display, also known as a HUD () or head-up guidance system (HGS), is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments. Although they were initially developed for military aviation, HUDs are now used in commercial aircraft, automobiles, and other (mostly professional) applications. Head-up displays were a precursor technology to augmented reality (AR), incorporating a subset of the features needed for the full AR experience, but lacking the necessary registration and tracking between the virtual content and the user's real-world environment.

Augmented Reality
Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D computer graphics, 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersion (virtual reality), immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory Modality (human–computer interaction), modalities, including Hearing, auditory, haptic perception, haptic, and Somatosensory system, somatosensory. The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, ...

Ride Height
Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point of the automobile, typically the bottom exterior of the differential housing (even though the lower shock mounting point may be lower); or, more properly, to the shortest distance between a flat, level surface, and the lowest part of a vehicle other than those parts designed to contact the ground (such as tires, tracks, skis, etc.). Ground clearance is measured with standard vehicle equipment, and for cars, is usually given with no cargo or passengers. Function Ground clearance is a critical factor in several important characteristics of a vehicle. For all vehicles, especially cars, variations in clearance represent a trade-off between handling, ride quality, and practicality. A higher ride height and ground clearance means that the wheels have more vertical room to travel and absorb road shocks. Also, the car is more capable of being driven on surfaces that ...

Air Suspension
Air suspension is a type of vehicle suspension powered by an electric or engine-driven air pump or compressor. This compressor pumps the air into a flexible bellows, usually made from textile-reinforced rubber. Unlike hydropneumatic suspension, which offers many similar features, air suspension does not use pressurized liquid, but pressurized air. The air pressure inflates the bellows, and raises the chassis from the axle. Overview Air suspension is used in place of conventional steel springs in heavy vehicle applications such as buses and trucks, and in some passenger cars. It is widely used on semi trailers and trains (primarily passenger trains). The purpose of air suspension is to provide a smooth, constant ride quality, but in some cases is used for sports suspension. Modern electronically controlled systems in automobiles and light trucks almost always feature self-leveling along with raising and lowering functions. Although traditionally called air bags or air bell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-link Suspension
A multi-link suspension is a type of independent vehicle suspension having three or more control links per wheel. These arms do not have to be of equal length, and may be angled away from their "obvious" direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 and later on their W201 and W124 series. Typically each arm has a spherical joint (ball joint) or rubber bushing at each end. Consequently, they react to loads along their own length, in tension and compression, but not in bending. Some multi-links do use a trailing arm, control arm or wishbone, which has two bushings at one end. On a front suspension one of the lateral arms is replaced by the tie-rod, which connects the rack or steering box to the wheel hub. Layout In order to simplify understanding, it is usual to consider the function of the arms in each of three orthogonal planes: *Top view: The arms have to control toe/steer and lateral compliance. This needs a pair of arms longitudina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
