Privacy filters – a Primer

Privacy filters, sometimes also known as light control film (LCF) such the 3M Vikuiti A-LCF and Optical Filters K-LCF consist of many thin louvers that function like a vertical window blind restricting the path of light through the filter. The display is clear and un-distorted to the user directly within the viewing axis, but to either side the image is blackened and un-readable.


There are a number of applications for displays where privacy for the viewer is required such as an outdoor privacy screen in an ATM, medical kiosk, in-flight entertainment screens and polling booths. Other applications are for contrast enhancement and light control such as pedestrian crossing units and head down avionics where the re-directed light limits the near field canopy reflections.

Privacy filters are offered either as standard plain or non-glare matte hard coated polycarbonate filters typically 0.5mm (0.021″) thick precision cut to final size, laminated into glass or plastic for thickness and extra ruggedisation, or integrated with a touch screen. Lamination with glass or plastic adds the options to have anti-reflection and anti-finger print coatings, chemically toughened glass and EMI shielding.

3M Vikuiti A-LCF is the established product replacing previous LCF-P and AG-LCF variations. Its continuous micro-replicated black embedded louvers is very high quality, but expensive:


Description 3M Vikuiti Advanced light control film
Louver angle sheets are 0° ±2°, typical bias to avoid display source interference +5° minimum
View angle 60° ±4° (30° either side of center)
Maximum sheet size 431.8 x 431.8mm (17 x 17″)
Thickness of film 0.53mm (0.021″)
Other thickness supplied by optical index match lamination
Finish Standard gloss (ABR0) or matt non-glare hard coating (ABR2)
Transmittance 70%
Operating Temperature -40 to +75°C (limitations of the lamination)

The K-LCF is a high value alternative to the 3M product. The privacy control is the same and the filters construction is similar to previous LCF-P types.

Description Optical Filters K-LCF
Louver angle + 15° ±3° standard bias to avoid display source interference +5° minimum
View angle 60° ±4° (30° either side of center)
Stock sheet size 17″ diagonal 270 x 340mm (louver parallel +15° to the 270mm side)
Larger sizes up to 1200 x 760mm (47 x 30″) to special order
Thickness of film 0.53mm (0.021″)
Other thickness supplied by optical index match lamination
Finish Standard plain or matt non-glare
Transmittance 75%
Operating Temperature -40 to +75°C (limitations of the lamination)

Alternative technologies

Blur film technology dispersed the incident light at particular angles and transmitting it at all other angles. The appearance therefore, changes from translucent to transparent depending on the angle from which it is viewed. This method was less effective when the distance of the filter to the display source was reduced and never become widely adopted. Production ended several years ago and it is no-longer available


CEE Thin-Client Market Forecast Revised Downward for 2014, in Spite of Impressive Q2 Growth in EMEA

The Europe, Middle East, and Africa (EMEA) thin-client market posted double-digit growth in Q2 2014 for the second quarter in a row


Thin-client shipments in EMEA increased by 15.3% year on year in Q2 2014, which corresponded to about 476,500 units. Shipment value also went up, by 22.2% year on year, to reach $169.65 million. Value has been growing faster than volume for the past six consecutive quarters, reflecting both stronger demand for more powerful hardware and an increasing demand for all-in-one (AIO) thin clients. The latter accounted for 4.5% volume share of total thin-client shipments in the region.

“It is worth noting that the influence of the migration from expired Windows XP, as a market driver for PC and thin-client renewals, will weaken by the end of 2014. As a result, thin-client growth will ease off as well,” says Oleg Sidorkin, senior research analyst at IDC. “In H1 2015, EMEA thin-client shipments could post a marginal decline, unless economic growth across Europe stabilizes sufficiently to become a strong market driver.”

WatchGuard Technologies’ New Policy Map Provides ‘X-Ray’ Vision into Firewall Configurations and Network Traffic

Newest enhancement to WatchGuard Dimension visibility solution allows admins to see policy misconfigurations and optimise traffic

9 September 2014 – WatchGuard® Technologies has announced the industry’s first interactive, integrated policy mapping capability for Unified Threat Management (UTM) and Next-Generation Firewall (NGFW) appliances. Available in the latest version of its real-time network security visibility solution, WatchGuard Dimension™, Policy Map provides a comprehensive view of traffic flow and policy impact across the entire network, with the ability to quickly filter or drill down for additional detail and analysis.


Security policies are central to firewall operation and according to a 2014 Verizon Report[1], there’s a strong correlation between a badly configured firewall and the likelihood of a security breach. Dimension Policy Map aggregates disparate information about policies, interfaces, applications and related traffic flows, and presents it in a simple, intuitive and interactive visualisation dashboard. It can be used for policy audit, to find active and misconfigured policies, identify unusual or abnormal traffic patterns, visually check if firewall policies or configuration changes have the intended impact on traffic patterns and much more.


“Security policies are the brains of a firewall and dictate the effectiveness of any firewall configuration and directly impact our customers’ network protection,” said Dave R. Taylor, vice president of corporate and product strategy at WatchGuard Technologies. “Given the tremendous customer uptake for Dimension on a global basis, we recognised an opportunity to improve their security management and help eliminate errors by giving network administrators a powerful tool for visualising policy analysis. They can now see policies like never before and instantly evaluate the impact on the network or user.”


Beyond Policy Map, the latest update to Dimension brings a variety of additional insightful reporting and new dashboard features that includes information on zero-day malware, details about website visits and traffic disposition, enhanced navigation, and consolidated CA certificate management. And it comes free on any WatchGuard UTM or NGFW platform.

IGEL Technology: Von der Green IT zum grünen Unternehmen

UD10__Energy_Star_web IGEL_Green_Company

The German thin client market leader writes climate protection and energy saving not only the product side quite large. With numerous internal projects IGEL is also working on its own life cycle and anchored the issue of climate change in corporate strategy.

Bremen September 9, 2014 – With its thin client solutions, IGEL offers an extremely energy-efficient alternative to the traditional desktop PC. So, for example, received the All-in-One Thin Client UD10 recently the Energy Star specification 6.0. Irrespective of the Bremen company sets but also to themselves an ambitious target and it has already made a decisive course: from the use of green energy, via the purchase of natural gas vehicles to the use of LED lighting. In an effort to reduce the environmental footprint consistently, now IGEL involved in the pilot project “green-transformation” as a model company. The goal: to protect the climate through the analysis of organizational structures and work processes are to be an organic part of the corporate culture. Climate-change agents to identify the various environmental aspects in the individual business areas and sensitize the IGEL staff for further joint processes of change.

Than previous milestones in climate protection IGEL can cite the company building built in 2009 at its headquarters in Bremen. It is built according to the valid regulations for energy saving and is supplied with green electricity. Beyond this, IGEL is 14001 (environmental management) according to ISO 9001 (quality management) and ISO. The living quality and environmental management is reviewed in annual audits by an independent certification body, thus improving constantly.

More action on climate change form the CO2 balance for the location Bremen according to GRI (Global Reporting Initiative), the switch to LED lighting in the warehouse and assembly as well as the equipment of the company fleet with environmentally friendly natural gas cars.

And the agenda for upcoming projects is well filled: Procurement management is to be more environmentally oriented, so that the CO2 emissions are further reduced during production, use and disposal of IGEL products. To better engage employees, also are plans for an idea management system and a “Climate Day”.

“To achieve climate protection goals in the company, it needs not only technical solutions,” commented Dr. Martin Schnatmeyer, Head of Quality, Environmental & Safety Management and Climate Change Agent at IGEL Technology. “It is important to involve all employees in the change processes. Through this involvement, many new ideas can arise also like to implement the colleagues voluntarily and with initiative. This motivation is the best basis for IGEL in all areas for green companies have to be. ”

Energy Star 6.0

In addition to the entrepreneurial efforts IGEL continues to work hard to improve its products under energy consumption aspects. So filled the screen integrated Thin Client IGEL UD10 now also follow the guidelines of the Engery Star 6.0, which classifies the maximum allowable electricity consumption over a certain period of time. This now has the majority of overall IGEL hardware product range over the environmental quality mark.

BYOD is smothering my security!

Security teams are struggling to keep up with the demands of traditional and mobile security. Craft a bring-your-own-device strategy that relieves the pressure.


Many security pros have commented that MDM, which stands for “mobile device management,” should stand for “mobile data management,” because data safety and security is the biggest concern.

Unchecked, mobile users can easily obtain corporate data from the network and share it publicly using their own email, text, and other communications software. This may violate a company’s own data security policies, and threaten its ability to comply with federal and state regulations.

Protect self service kiosk users from dangerous bacteria like E coli and MRSA with SeePoint’s antibacterial coated kiosks. In kiosk installations where bacteria transmission is a concern, SeePoint’s trained technicians can apply this antibacterial coating, the Aegis Microbe Shield, to keep touch screens and keyboards free from bacteria, spores, viruses and fungi. Coated touch screens and keyboards also provide surfaces where bacteria and other microbial contaminants cannot grow.

Antibacterial coatings are highly recommended for kiosks used in hospitals, public areas, high traffic installations, government self services and retail display fixtures. In use since the mid-1970s, the Aegis Microbe Shield is a safe and effective antimicrobial technology that combats contamination on frequently touched surfaces such as kiosk keyboards and touch screens. The antibacterial coating used on SeePoint kiosks is a permanent protective shield that kills 99.4% of all microbes.

In the air
In the soil
On our skin and bodies
On items we touch every day
Antimicrobials control, destroy or suppress the growth of microbes, eliminating or limiting the negative effects of contamination, staining and deterioration.

Permanently bonded to the touch screen surface, the resistive membrane of the antibacterial coating does not affect display clarity on the touch screen. The antibacterial coating is also safe for the user and the environment. The coating does not leach in the environment, migrate to a user’s hands or wear off when the screen is cleaned. Unlike other products, the technology of this coating does not allow microbes to adapt or create resistant organisms.

The Aegis Microbe Shield works by physically rupturing the microbe. The compound used in the coating consists of a long molecular chain that looks like a sword which, at its base, has a permanent bonding property. The permanently bonded “sword” sticks up from the surface where it has been applied, ready to puncture the microbe. When the microbe comes into contact with the sword, the microbe is punctured. Then the sword’s base, which includes a nitrogen molecule, draws the microorganism to it and electrocutes the cell. The microbe is destroyed on the sword. In the process, the coating is not consumed or dissipated so the antimicrobial is not depleted.

Bonds directly and permanently to the surface on which it applied.
Remains in place and active even after multiple washings.
Can be applied to almost any surface material.
Does not migrate from the surface.
Does not transfer onto the skin.
Does not leach harmful toxins into the environment.
Is not poisonous.
Does not dissipate over time.
Physically controls the microbe on contact.
Is proven successful in demanding settings such as medical facilities and clean rooms where safety and effectiveness are paramount.
Does not create an environment for adaptive organisms and “super bugs.”

3 Reasons VMware, Inc.’s Shares Could Fall

3 Reasons VMware, Inc.’s Shares Could Fall
Motley Fool
VMware (NYSE: VMW ) stands at a crossroads right now.


When VMware was a brand-new OpenStack Foundation member, OpenStack insiders worried the addition would destroy the platform from within. “For its $200,000 annual gold member fee VMware just elegantly subdued one of its most feared competitors and we, at the foundation board, allowed that to happen. I fear it may have been the board’s first wrong decision,” said OpenStack board member Boris Renski at the time.

But that hasn’t happened. Instead, OpenStack has become a serious growth driver for major backers such as Red Hat and Rackspace. And rather than subverting OpenStack from the inside, VMware is making a serious effort to build platform support into its own products.

About Thin Client Computing

Since 1999, has been reporting the thin client computing market as well as the ChromeBook, Zero Client, Android clients, Pi Raspberry Clients and Thick Client market. Generally the cloud computing market since it started with companies such as Citrix back in the late 80s.

A thin client is a lightweight[vague] computer that has been optimized for establishing a remote connection with a server-based computing environment. The server does most of the work, which can include launching software programs, performing calculations, and storing data. This contrasts with a fat client or a conventional personal computer; the former is also intended for working in a client–server model but has significant local processing power, while the latter aims to perform its function mostly locally.

Thin client hardware generally supports a keyboard, mouse, monitor, jacks for sound peripherals, and open ports for USB devices (e.g., printer, flash drive, webcam). Some thin clients include legacy serial or parallel ports to support older devices such as receipt printers, scales or time clocks. Thin client software typically consists of a graphical user interface (GUI), cloud access agents (e.g., RDP, ICA, PCoIP), a local web browser, terminal emulators (in some cases), and a basic set of local utilities.

New hardware interfaces include socket-based enabled devices eliminating the need for a physical USB connection. Bluetooth wireless connectivity is also a big factor for devices.
