Essays on Actuators.

Most organizations in business use the old methods that employ the use of databases analyzed to provide information for business models. The information passes through departments after departments until they finally reach the top of the organization. The information gathered from public sources, the internet and information providers. Michael Chui, Markus Loffler, and Roger Roberts write of a futuristic technology that is growing as an alternative source of primary information. The new technology is creating a business model that improves business processes while reducing costs and risks. In addition to providing new business models, the new technology is making the corporeal ...

Medical technology is greatly improving and would soon enter the stage where we do not need to regularly inject insulin or use finger prick blood tests to monitor diabetes. The advancement in the field of biosensors will open up a whole lot of opportunities. One of them is the efficient monitoring of the blood sugar levels with a small sensor implanted under the skin. Such devices can also release insulin when needed and also communicate the details to a smartphone connected to them (Coleiro, 2013). Biosensors have not only its application in diabetes monitoring. It exhibits state of art applications in a number ...

Introduction

Giraffe OmniBed is new medical technological device which brings together the features of a radiant warmer as well as an incubator. These top features are harmonized in a single device to make it a very effective medical device. The two features of a Giraffe OmniBed cater for traditional infant care products, and this makes the device pivotal in the medical industry. The device is manufactured and assembled in such a way as to minimize heat loss as much as possible. This also ensures thermal stability through its bi-directional characteristics. The design of this medical device helps the infant to get the optimal amount of ...

Introduction

Mechanics is a branch of physical science that deals with moving and stationary bodies influenced by forces. It is divided into two branches called dynamics and statics. Dynamics deals with moving bodies while statics deals resting bodies Mechanics also has a subcategory called fluid mechanics. Fluid mechanics is the science concerning the behavior of fluids. It could be fluid statics when it tackles about the body at rest. On the other hand, it could be fluid dynamics when the fluid body being studied is in motion. Fluid mechanics is a study regarding the behavior of material that can bend and ...

Introduction

Process control is the process where technologies is required to be implement and design control systems in the process industries. The main objective of the process control is to maintain and bring about the conditions of the process at optimal values. It includes computer simulation and optimization, physical and empirical modeling, automation of hardware and software, control structure design and many others. Process industries are the process where material and energy streams interact and transform each other. It includes continuous sequential processes that refer to process units, enterprises, and whole plants. Additionally, process components are also prevalent in other ...

Analysis of system diagram

Linear actuators favor movement of an object in an exact straight line. Now let us discuss about the system diagram of a simple molding machine. The simple machine has three linear actuators one being used for opening and closing of mould, the second being used for the barrel movement, the third for injecting polymers. Fig1.1 represents the block diagram of a simple molding machine. As mentioned before, it has three linear actuators. The linear actuator1 as shown in fig1.1 controls the opening and closing of the mould. Once the mould is closed, the barrel can be moved forward or backward. ...

Big Dog

Picture of BigDog The robust legged robot, BigDog, is developed by Boston Dynamics. It is the first quadruped robot in the human history that moves at human walking speed. Designed as a pack mule and used for the U.S. military purposes to carry heavy items in rough terrain. The machine is capable of carrying upwards as much as 40 kilograms of weight. The robot has four stable legs with active balance sensors to ensure stability. Each leg has four joints with actuators. The version V3 will have an additional joint of the leg for even steeper climbing at a higher ...

Control Valves

A valve is a control device that is utilized in adjusting the flow rate of a fluid in a pipe (Doddannavar, Barnard, and Ganesh, 2005). This implies that the flow rate will change as the valve opens and closes either partially or fully, thus providing some obstruction to some extent (Rennels and Hudson, 2012). The valve comprises a flow passage in which the flow area can be varied. Operation of valves in most scenarios is manual. In cases where the valves are operated automatically, electromechanical actuators are used. The electromechanical actuators can include electric motors or pneumatic actuators that are motorized by air ...
