OTE Group, based in the Netherlands, specialized in manufacturing and exporting vial lubricating, moisturizing and cleansing for contact lenses. Along with three production lines, the company offers more than 100 brands to bring their brand to customers. OTE desired product to the customer must be in perfect condition.

Going along with that, OTE must meet the strict requirements of the pharmaceutical and healthcare industries. Previously, the quality control is done by hand, but when faced with the requirement to improve the quality of products meet ISO standards, the company has to find solutions to the image sensor to ensure the presence of product code and the label on the bottle. Using the image sensor to ensure quality control and help improve the efficiency and speed performance.
Image sensor is a simple solution and moderate price, for checking the presence of products and components in the packaging process. Specifically, an image sensor can replace multiple sensors or perform the function of optical sensors can not be done.

Three image sensors are installed on the packaging line's OTE. Here, the image sensor checks the presence of the code in the bottom of the bottle and the label.

In the first application, without code, line stops.

OTE has more than 250 customers each label for many customers. They should ensure that the correct label is affixed to the bottle. With this application, an image sensor used for round bottles, and two image sensors are used with specially shaped bottle.

Image Sensor Solutions helped secure OTE and code printed on the label, no longer have to rely on the random test and meet the stringent requirements of customers in the pharmaceutical industry.

Digital Single Lens Reflex (DSLR) Camera

dslr


DSLR cameras, also called DSLR (Digital-SLR, SLR English with Single lens reflex) are a type of photographic camera single-lens reflex type (SLR), which support storage of the captured image is an electronic sensor rather than 35 mm film used in chemical photography. Among its most important features is the use of control systems for automating most of the mechanisms of both sealing devices,

Synchronization with flashes (both internal and external), and generally most camera functions, although still behave in most respects (approach shot, stabilization) as electromechanical devices like their predecessors. In most cases remain the same features (and compatibility, depending on the manufacturer) for the traditional SLR system, popularized worldwide since 1959 Nikon F.

The first difference is that the lenses are interchangeable, compatible with the objectives of SLR film (depending on manufacturer). Because these objectives were designed for 35mm film, the sensor is larger than in compact cameras. While it may be the same size of a movie (36x24 mm) (full-frame sensor, usually only in very high-end models), usually tend to be somewhat smaller (see: APS-C size sensor), in which If a 'multiplying the focal length "normally 1.5 (Nikon, Pentax, Minolta, Sony), 1.3 and 1.6 (Canon) or 2x (Four Thirds) occurs.

In compact cameras small size sensors are used, leading also shorter focal lengths and therefore a very high depth of field (almost everything in the picture into focus). The depth of field is therefore the main difference between a photograph taken with a digital compact camera or an SLR. With an SLR great control is achieved by the free choice of the ratio of the focal length and aperture, as a defocused focuses on the subject photographed.

Another advantage of an image sensor larger is the highest image quality and increased sensitivity, being able to take pictures with high ISO values with very acceptable noise level.

DDR3 Ram

DDR3 Ram


The processor has to take the data and instructions for it to function. However, the rates at which it works, the memory of which takes the data and instructions must be flash. Or, what is the same, ultracara. For this reason, we have created different hierarchical levels of memory.

The fastest and closest to the processor cache, with levels 1, 2 and 3. The L1 is up flash and expensive, and therefore does not exceed a few tens of kilobytes. Sandy Bridge is 64 Kbytes divided into 32 Kbytes for data and 32 for instructions. The level two cache, L2, and becomes more than 100 Kbytes, with up to 256 or 512 Kbytes. The Level 3 or L3 unfolds with several "megas" up to 16 Mbytes. These three levels are integrated in the processor, while the next, RAM, is out, as memory modules.

And finally, the slower cheaper memory but also corresponds to the hard drives, optical drives and Flash memory. These systems are just a support for loading data into RAM. And is that a hard drive can not run anything directly; just loaded into RAM.

The processor first searches its records, then the L1 cache, then the L2, L3 and finally, in RAM. Anything having to go for a data memory means slow down the operation, the more the higher is the data in the memory hierarchy.

Today, memory is DDR3 par excellence. After a long transition, also prompted by integrating memory controllers on processors, DDR2 is alone for old computers, while DDR3 has been expanding both laptops and desktops and netbooks. The fall in prices has been remarkable too, with bargains of up to 10 euros per Gbyte or less.

For extreme memory speeds can reach up to 60 euros per Gbyte, for memories DDR3-2.300. They are positioned as solutions at the end of overclocking performance professionals. Typically will work in speeds between DDR3-1.333 and DDR3-2.000. What is clear is that today having 8 Gbytes of RAM is not a luxury, not even on laptops, where 4 Gbytes on a 1,333 SODIMM module cost around 30 euros.

But these differences in prices are not justified by performance tests, at least for the vast majority of users. In fact, you may find prices of less than 7 euros per gigabyte. Curiously, for SSD price per Gbyte is around 2 euros.

How To Boost The Speed Of Wi-fi

Many users often lose almost a third of the speed of internet connection paid when using Wireless. Below we discuss some "tips" that we consider relevant to increase internet speed by improving your wifi network.

Step 1: Reduce interference to increase internet speed

The first step in solving the problems of WiFi performance is to understand what causes it. In most cases is signal interference from other neighboring wireless networks and devices. Our wireless devices help to create a wall of electronic noise with the WiFi network must deal. It would be like trying to have a conversation with someone who was in another room and that both had noise.

Outdated equipment of your neighbors can influence the performance decrease your WiFi network. The points of access routers WiFi and former operating in the 2.4 GHz band limited thus slowing the connection.

Their electronic devices may also be working on influencing the efficiency of your network. Cordless phones and microwave ovens used increasingly congested 2.4 GHz band.

Step 2: When you upgrade to a Dual-Band (2.4 and 5 GHz) device get speed up internet

What do we do when we find much traffic on the freeway? Normally, we try to find an alternative route, preferably where there are fewer cars. The same idea applies to WiFi networks. The band's most recent 5 GHz has been described as an almost empty freeway, and has become the standard for modern high-end electronic devices such as game consoles, TVs and digital media players such as Apple TV and Roku. The Dual-Band Wireless routers today offer the best of both worlds: surfing the web on older devices 2.4GHz and increase internet speed to play and view streaming HD videos through the 5 GHz band, all without being affected the performance of the network.

When you go to buy a Dual Band router, be sure to find one that allows connection to 2.4 GHz and 5GHz. Some older models must be established only in bandwidth. We suggest routers as NBG5615, NBG5715, NBG6503 or NBG6716 Zyxel or Access Points as the NWA1123-NI or NWA5123-NI also Zyxel, these are Dual Band devices that meet international standards WiFi 802.11 a / b / g / no 802.11 b / g / n 2.4 GHz and 802.11 a / n / ac 5 GHz in the case of APs.

Step 3: Importance of Location

Traditionally it has been said that location is everything when it comes to business. It's the same when it comes to the integrity of the WiFi signal. The placement of access points and router in areas of poor accessibility leads to poor quality signals, shaded areas and loss of connectivity.

The wireless router must be located as close as possible to the central part inside your home. If you are trying to provide a signal to several plants, it is important to think in three dimensions. Consider placing the router on the second floor for a more complete coverage on the top floor and bottom.

The walls, windows, large objects or other barriers, weaken the WiFi signal. Find an open as a desktop or a central wall space. Do not hide your router in a narrow or behind a large electronic device such as a TV or a computer cabinet.

Step 4: Do not run security risks increase internet speed

To avoid any unwanted access to your network is very important to take the necessary protective measures and do not skip the security protocols, updating and maintaining security settings.


The new routers have security protocols WPA and WPA2, which have replaced the WEP protocols (less secure today). Some cheaper models of these new protocols can slow connection speed, but it is not advisable to disable security for greater speed. Instead, consider buying a router with hardware optimized for the latest security protocols. This will keep the overall network performance while protecting your data from hackers.

Dynamic Host Configuration Protocol (DHCP)

DHCP_Serve


DHCP (Dynamic Host Configuration Protocol) simplifies the assignment of IP addresses on a network. What is needed is to at least one DHCP server. Distributes IP addresses to the different clients.

On the server side, an address space is defined. IP addresses from this pool are allocated to the clients when they ask the DHCP server for it. For this to happen, the network configuration of the client must be set accordingly. This is now standard on operating systems such as Linux and Windows is the case, so that an administrator does not have to worry about the settings of the client.

A DHCP server automatically, manually or dynamically assigns IP addresses. Automatically addresses can be assigned only once. It receives a client that is identified by the MAC address of its network interface, at first logon the network a free IP address. Which is bound to the MAC address, and the client gets it in the future at each login. In contrast, dynamically distributed IP addresses are cashed by the server after a certain time.

The latter method should always be used in the larger network, otherwise the IP addresses could be almost there. Caution: This can happen even in smaller networks, if one uses often times virtual environments such as VMware Workstation, Parallels Desktop or Citrix XenServer. These generate multiple virtual network interfaces depending on configuration. The most cumbersome method, but certainly is used, is the manual assignment of IP addresses. Here you can assign a specific address one or more clients an administrator - such as a router or a network printer.

The request from the client by means of broadcast. Thus, to test how many DHCP servers exist on the network. The contacted server is sent in response a suggested configuration. If the client accepts this, it sends a DHCP request (DHCP request). The server in turn sends the IP address and the required parameters. At the end of the session, the client sends a release back to the server and reports so that the IP address is no longer needed (DHCP Release).
