“…A savvy bed structure can perceive the recognized focuses where bedsores often occur, i.e., In light of the typical body size by age, occiput, scapula, short fibers projection, elbow, iliac peak, lumbar, pubic bone, Achilles ligam. As shown in Figure 1 [15].…”

Most mishaps happening at clinical foundations treating older patients with portability hindrance are bedsores and slip-and-fall accidents. One reason for this high pace of mishaps is the absence of nursing faculty. So as to help parental figures in nursing old patients who are unable to move freely, we offer an arrangement and implementation of a wise bed in this work. This is the bed. Under the sheet material spread, a couple of weight sensors are passed to consider the two social orders' regular actual characteristics as well as the specific body portions where bedsores commonly arise. The body zone is divided into three vertical territories and three level zones to cope with the weight ulcer territory and prevent falls. Each microcontroller unit is in charge of monitoring pressure-differentiating data in one of the bodily regions separated on a level plane. In this review, a consistent weight distinguishing figure is offered that is useful for predicting the anticipated outcomes of bedsores and falling setbacks by taking into account both the strength and the length of weight of unambiguous body parts. Our preliminary findings reveal that a model magnificent bed serves a pair of human models of varied heights and burdens admirably.

“…Elevators are very important with high-rising buildings [1]- [3], however, these electrical transport systems can account for a considerable proportion of energy consumption in buildings while the regenerative braking energy obtained by operation modes of elevators at the time of lifting-up with light load and liftingdown with heavy load is burned on the braking resistors, causing wastage and air pollution [1]- [2]. Therefore, improving the energy efficiency of elevator operation has attracted more attention from manufacturers and researchers, most of whom have proposed various energy saving solutions applied in practice [4]- [9]. Priyanka Priyanka Kubade, and S. K. Umathe [10]; A. Rufer, and Philippe Barrade [11] recovered regenerative braking energy by supercapacitors energy storage device and reutilized it when the more energy is required by another elevator motor; M. Shreelakshmi, and Vivek Agarwal [12] combined fuel cell for the ride-through operation with supercapacitor bank for storing the regenerative braking energy; Shili Lin, Wenji Song, Yongzhen Chen, et.…”

Elevators- means of vertical transportation to carry people and goods are an indispensable part in offices, high-rise buildings, hospitals, commercial areas, hotels, car-parks when blooming urbanization develops worldwide. However, the level of energy consumption in elevator operation is significant, so energy saving solutions have been outlined and applied in practice. With frequent braking phases, regenerative braking energy is wasted on braking resistors. Therefore, this paper proposes regenerative braking energy recuperation method for elevator operation in building by active rectifiers enabling the braking energy to be fed back into utility grid. Simulation results conducted by MATLAB with data collected from OCT5B building-RESCO new urban area, Ha noi, Vietnam have verified saving energy of using active rectifiers replacing diode rectifiers up to 33%.

Direct torque control "DTC" technique is one of a high performance control system of an AC motor drive, which was proposed after the vector oriented control scheme during the resent 25 years. It has been developed rapidly for its concise system scheme, transient and dynamic performance. The DTC mechanism consists of voltage vector selection table, two hysteresis comparators and two estimator's one for stator flux and another for electromagnetic torque. DTC is directly control torque and flux by using Voltage Source Inverter VSI, space vector and stator flux orientation and indirect speed regulated. A several control techniques can be used for improving the torque and flux performance. In this paper, the DTC with Proportional-Integral-Derivative (PID) controller used to improve the starting and dynamic performance of asynchronous motor AM, which gives good torque and flux response, best speed control and also minimize the unacceptable torque ripple. The mathematical model of DTC with PID controller of 3-phase induction motor IM are simulated under Matlab-Simulink. Therefore, the DTC based on PID controller has good performance of IM compared to classical DTC for starting, running state and also during change in load. 618 that the DTC with PID controller has many merits simple realization, fast speed control, best starting and running characteristics over the classical DTC. All results are getting by using Matlab simulation [10]. MATHEMATICAL MODEL OF A 3-PHASE INDUCTION MOTOR DRIVEA model of three phase induction motor drive can be obtained when it is acts under normal and dynamic condition. Therefore, the variables quantities of IMD such as stator and rotor current, stator and rotor voltage, stator and rotor flux, and electromagnetism torque can be determined from this model [11,12]. The description model of a 3-phase IMD can be represented by differential equations when the main three phase stator and rotor quantities such as current, voltage, and flux are transform to stationary frame or two axis theory frame "d-q axis" by axis transformation. A 3-phase IMD model implemented based on the stationary reference frame [13,14]. The per phase equivalent circuit of 3-phase IMD in d-q axis is shown in the Figure 1, which used for implementing this model and the equations of stator and rotor quantities written as equations.
