232 results about "Universal design" patented technology

Universal design is the design of buildings, products or environments to make them accessible to all people, regardless of age, disability or other factors. The term "universal design" was coined by the architect Ronald Mace to describe the concept of designing all products and the built environment to be aesthetic and usable to the greatest extent possible by everyone, regardless of their age, ability, or status in life. However, it was the work of Selwyn Goldsmith, author of Designing for the Disabled (1963), who really pioneered the concept of free access for people with disabilities. His most significant achievement was the creation of the dropped curb – now a standard feature of the built environment.

MAPSK self-adaptive demodulating system

The invention discloses a MAPSK self-adaptive demodulating system based on characteristics of MAPSK signals and combined with a self-adaptive data transmission frame structure. A self-adaptive signal demodulation processing flow includes the steps of descriptor header capture, bit synchronization, conversion of a rectangular coordinate system into a polar coordinate system, estimation on initial frequency offset and phase offset, RM decoding, carrier tracking, gain control, software decoding mapping, burst type solution and frame synchronization. The step of bit synchronization includes the processes of bit timing offset estimation and trigonometric function interpolation. According to the MAPSK self-adaptive demodulating system, general design for burst self-adaptive demodulation on signals with variable rates (2-45Mbps) and various modulation modes (QPSK, 8PSK and 16APSK) is achieved. The MAPSK self-adaptive demodulating system solves the problem of serious rain attenuation in wireless transmission in the Ku/Ka frequency band through a satellite, and achieves the purpose of meeting different data transmission demands of various types of communication terminals and the purpose of meeting the demand for anti-interference communication of communication satellite systems.

Automobile steering column installation structure

The invention discloses an automobile steering column installation structure and belongs to the field of automobile manufacture. The automobile steering column installation structure comprises an instrument cross beam, a middle path connecting piece, a steering column installation bracket and a player connecting bracket, wherein the middle path connecting piece is arranged on the middle of the instrument cross beam; the steering column installation bracket is installed on one side of the middle path connecting piece on the instrument cross beam; the player connecting bracket is arranged on the other side of the middle path connecting piece on the instrument cross beam; and the instrument cross beam is fixedly connected with the braking pedal installation bracket of an automobile by virtue of a first bracket, is fixedly connected with the accelerator pedal installation bracket of the automobile by virtue of a second bracket and is fixedly connected with the front baffle of the automobile by virtue of a third bracket between the player connecting bracket and the middle path connecting piece. Three connection structures of the instrument cross beam and an automobile body are additionally arranged in the automobile steering column installation structure in the embodiment of the invention, so that the output frequency of an automobile engine is effectively avoided, and meanwhile, the weight is reduced by about 50% relative to a general design instrument cross beam assembly.

Universal design calculation method for deep/shallow-buried vertical surrounding rock pressure of tunnel and underground space

The invention discloses a universal design calculation method for deep / shallow-buried vertical surrounding rock pressure of a tunnel and an underground space. The method comprises the following steps of: 1, determining shapes and sizes of the tunnels and underground spaces: buried depth (H), unlined tunnel semi-width (alpha), stratum sliding surface semi-width (alpha1), tunnel height (y) and tunnel length (L); 2, determining physical parameters according to geological conditions and surrounding rock levels of the tunnel and the underground space: surrounding rock cohesive force (c), internal friction angle (phi), unit weight (gamma), Poisson ratio (mu) and initial side pressure coefficient (xi); 3, calculating and designing the following contents according to above known physical parameters: 3.1 average vertical ground pressure <delta>flat of the tops of deep / shallow caverns; 3.2 deep / shallow buried boundary depth Hmax, wherein the tunnel is a shallow-buried tunnel when the buried depth is less than Hmax, and the tunnel is a deep-buried tunnel when the buried depth is greater than or equal to Hmax; and 3.3 vertical ground pressure of the shallow-buried cavern. According to the method, no load mutation phenomenon is generated at the deep / shallow-buried boundaries, and through plenty of actual measurements and verifications, the condition is identical to the practical condition.
