Light source

White polychromatic light provides stable, homogeneous illumination of the optically precisely focused measuring volume Particle

Detector

The high -resolution photomultiplier records every signal in real time – thus every particle is counted, and its size is determined

Every single particle scatters light, thus creating a clear light pulse signal

Clean air for our children in schools

Measurement of indoor air quality

• Measurement of aerosols down to the size of a virus (175 nm)
• Measurement of CO² as an indicator of "used air"
• Automated evaluation of infection risk by determining a reproduction number

Air quality measurement during two school hours

Without room air purifier with ventilation With room air purifier without ventilation

Reliable protection for medical staff

Testing masks for protection against viruses

• Exact analysis of mask filter efficiency e.g. for the corona virus
• Measurement of respiratory masks according to standards (e.g. FFP2, KN95)

Penetration of various very good FFP2 masks as a function of particle size

Permeability of 114 tested masks in hospitals

• 34.21% of the masks do not meet the test according to the EN149 standard (total permeability > 6%)
• 64.91% of masks do not provide sufficient protection against viruses (permeability in the range of viruses > 6%)

Identifying the risk of infection & preventing the spread of viruses

Determining the number and size of exhaled aerosols

• Detection of super spreaders / infection drivers
• Diagnosis of disease progression

Example of the disease progression for a SARS-CoV-2 infected person in October 2020

• Only about 10% of infected people spread the virus further and breathe out more aerosols / viruses
• These "super-emitters" can be detected / measured
• "Super-emitters" exhale up to a factor of 100 more aerosols than healthy persons

The lung as source of aerosols and information

• A completely new measuring device for infection control
• The measured information offers potential for medical diagnosis
• A study is currently conducted at the Frankfurt University Hospital where 80 SARS-CoV-2 infected persons were measured
• The data is comparable to the first X-ray image, the available information offers many possibilities for analysis

Bertha Röntgen has to sit still for more than half an hour on 22 December 1895. That is how long her husband Wilhelm Conrad Röntgen irradiates her hand. Bertha's patience is rewarded: today, the image is considered the most spectacular X-ray image

• The task is to develop a concept for a control centre, which will be implemented and evaluated within the framework of the innovation lab
• A particular challenge is the integration of immense data streams from a wide variety of sources into the "mobility data room" and the development of a corresponding cyber security policy
• Special equipment is being developed specifically for the project in accordance with the so-called KRITIS criteria for critical infrastructures

TREND CLIENT / PROJECT APPLICATION

Matrix switches and extenders help to increase operational efficiency and to ensure employee protection at MTU's engine test center

Contribution of IHSE

• The test control station and the actual test laboratory are physically separated to ensure protection from noise and potential hazards (e.g. engine damage)
• Improved operational efficiency through increased network uptime and equipment availability

TREND CLIENT / PROJECT APPLICATION

The U.S. civil air traffic control system relies on IHSE's high-end KVM and AV solutions to increase operational efficiency and to enable fail-safe management of all flights for Project ERAM (En Route, Modernization, Automation) Contribution of IHSE

• Track 74% more aircrafts simultaneously through higher data availability
• Three-tier redundancy concept that increases reliability and enables 24/7 operation
• Improved operational efficiency, reduced emissions and reduced workloads

The Bikeleasing Offer

The Bikeleasing offer is aimed at companies that want to motivate their existing employees and retain them for the long term, as well as attract new employees.

In doing so, any company can offer its employees great benefits at no effort or financial expense on their part!

The Facts

Since 01.01.2020, company bikes are taxed according to the new 0.25% rule

0.25% rule:

0.25% of the gross list price of the bicycle (1% of the quarter of the manufacturer's recommended retail price rounded down to a full 100 euros) is added to the employee's taxable salary (so-called non-cash benefit). By taxing the non-cash benefit, the private use of the bicycle is expressly permitted.

• If the costs are fully covered by the employer, there is no salary conversion for the employee and thus no taxation of the non-cash benefit (applies to bicycles and pedelecs up to 25 km/h).
• For s-pedelecs (up to 45 km/h), the 0.25 % rule always applies, regardless of who bears the costs of the leasing.

Why is Bikeleasing so successful?

Digital B2B Platform

For the highly automated arrangement and management of leasing contracts

The complete process, from onboarding of the employer, employees ordering the bicycle from the retailer, through to the processing of damage claims is highly automated and carried out via the inhouse digital platform and mobile app.
