2401.全球DC电源系统市场报告（2015-2019年）
[计算机、通信和其他电子设备制造业,电力、热力、燃气及水生产和供应业,仪器仪表制造业] [2015-06-14]
DC power systems are electrical structures that supply voltage or current of fixed polarity, either positive or negative. Such systems can be powered by an alternating current (AC) or a direct current (DC) source. A simple DC power system consists of a transformer, rectifier, filter, and regulator, all of which work to provide a constant and ripple-free DC output. DC power systems largely find applications in telecommunications, data centers, and transportation. However, they are also used in the oil and gas, consumer electronics, and automotive industries.

Drill collars are an essential part of the drill string. They form the lowest component of the drill string. Drill collars are heavy, thick-walled steel pipes with threaded connections at both ends. The end with an external thread is known as the male end, whereas the end with an internal thread is known as the female end. The basic purpose of a drill collar is to provide the necessary weight for drilling purposes. Drill collars are machined out of solid steel bars as per API specifications. They are manufactured from standard steel (usually plain carbon steel) or a non-magnetic alloy of steel and copper or other non-magnetic alloys. The bars of solid steel are bored from one end to the other to provide passage for drilling fluids. There are usually two types of drill collar: slick and spiral. Standard drill collars are about 9 meters in length. Drill collars are characterized by high tensile strength and fatigue resistance. The various uses of drill collars are.

2403.全球光学成像市场报告（2015-2019年）
[仪器仪表制造业,计算机、通信和其他电子设备制造业,专用设备制造业,医药制造业] [2015-06-14]
Optical imaging is a non-invasive imaging technique that uses non-ionizing radiation to look inside the human body for the purpose of diagnosing disease. Non-ionizing radiation, such as visible, UV, and infrared light, is used to generate detailed images through electron excitation. Optical imaging, along with MRI and X-rays, can be used by doctors and researchers to obtain better information about diseases by enhancing their view of organs, tissues, and smaller structures (including cells and molecules).

2404.全球透视和移动式C臂市场报告（2015年-2019年）
[计算机、通信和其他电子设备制造业,医药制造业,仪器仪表制造业] [2015-06-14]
Fluoroscopy uses X-rays to obtain real-time moving images of the internal organs of the body. Physicians use this imaging technique to examine the structure and function of organs during interventional and diagnostic procedures. The method is widely used in orthopedic surgery, angiography, placement of catheters, and implantation of cardiac rhythm management devices. C-arms are precise and accurate devices that reduce patient discomfort during surgical and non-surgical procedures. They have radiographic capabilities and are used for imaging during various critical, surgical, orthopedic, and emergency care procedures.

2405.全球微型投影仪市场报告（2015-2019年）
[计算机、通信和其他电子设备制造业,专用设备制造业,仪器仪表制造业] [2015-06-14]
A projector is a portable optical device that projects images on any surface or screen. Traditional projectors and pico projectors are the two types of projectors available; the latter is preferred over the former for its tiny size, light weight, and easy portability. Traditional projectors, in contrast, are bulky and difficult to carry around.

2406.全球头戴显示器市场报告（2015-2019年）
[仪器仪表制造业,计算机、通信和其他电子设备制造业] [2015-06-13]
An HMD is a display device that has one or two small displays with lenses and semi-transparent mirrors embedded in it, to make it look like a pair of eye-glasses. This device consists of an image source, collimating optics, and a mechanism to mount the device onto the head. The wearable device projects images in front of a user, relative to the user's line of sight.

2407.美国体外诊断测试IVD市场报告（2015-2019年）
[仪器仪表制造业,医药制造业] [2015-06-13]
IVD tests help in diagnosing, screening, and managing diseases in humans and animals. The tests are usually performed in a controlled environment. IVD tests provide a valuable health status of patients without having a direct therapeutic effect. Hence, they play an important role in supporting decision making in clinical conditions. Advances in IVD have led to the development of POC and self-testing, which are easy and convenient for both patients and medical professionals. IVD tests can be performed in a variety of settings including a clinical laboratory, a physician’s office, or at home.

2408.美国中心静脉接入设备市场报告（2015-2019年）
[专用设备制造业,医药制造业,仪器仪表制造业] [2015-06-13]
A central venous access device is a small, flexible tube inserted into an individual's central circulation system to administer medication and fluids, collect blood samples, and measure venous pressure. These devices, made of non-irritating materials such as silicone to reduce the side effects of long-term use, are placed in a large vein by surgeons or interventional radiologists, with or without general anesthesia. They are used in cases where a patient cannot or must not eat; medication must be delivered over a prolonged period of time or only via an IV, such as chemotherapy; repeated transfusions of blood or blood products and frequent blood sampling is necessary; and there is difficulty in obtaining peripheral venous access. CVCs, PICCs, and implantable ports are common types of central venous access devices. Thrombotic, mechanical, and precipitate vascular occlusions are common complications associated with these devices.

[仪器仪表制造业,汽车制造业] [2015-06-12]
Air filters improve ignition, horsepower, and mileage of an automobile. They also improve air flow to the engine and the emission control system, enabling proper ignition of fuel. The production of air filters has gained momentum mainly because of the high demand in the aftermarket, as they need to be changed at regular intervals. Based on type, the air filters are segmented into cabin and intake air filters.

2410.全球柔性内窥镜市场报告（2015-2019年）
[医药制造业,仪器仪表制造业,计算机、通信和其他电子设备制造业] [2015-06-11]
Flexible endoscopes consist of a flexible insertion tube equipped with fiber-optic glass rods, a camera, and ports that allow a physician to access and visualize the internal diseased areas of the body, to collect tissue samples, and to insert devices that help stop internal bleeding. The equipment is relatively safe and can be used to view parts of the body that are otherwise difficult to access such as the intestines. However, flexible endoscopes are expensive, fragile, and provide lower quality images than rigid endoscopes.
