Our specialties are networking security, troubleshooting networking protocols, and investigating interface issues. We also develop software for the analysis of measurement data and for numerical simulations of heat pump systems.

This an offering targeted to small businesses and private home owners with sophisticated building / IT technology - but we draw on experience with supporting the IT departments of global enterprises since many years.

'Internet of Things' - the buzz word for interfacing appliances and building technology with a computer network connected to the internet. Challenges are: Securing remote access - in particular if external companies have to support devices, troubleshooting interoperability issues, and missing or incorrect documentation.

We analyze and solve communication issues via 'Reverse Engineering', dig into existing monitoring data and vendors' documentation, and if needed we act as 'translators' in discussing issues with suppliers.

Data Analysis. We help you with consolidating your 'Big Data' and with compiling useful technical performance indicators (or commercial ones). We believe that a lot can be done by utlizing tools you might already own, like Microsoft Excel.
As physicists and engineers we can support particularly with calculations related to heat transfer and energy storage.

We don't sell black-box-style computer code, but we deliver consulting, guidance, and 'help to your yourself' on top - or as an alternative to - programming services. You should be able to know the inner workings of your system, and to build on our know-how to maintain and extend it yourself.

[ ► Calculating heat pumps' performance - different definitions of 'averages' ]
[ ► Analysis: One year of PV power generation and smart metering  ]

Simlation of temperatures and volume of ice for the 'ice storage powered' heat pump system

Numerical simulations of an 'ice storage powered' heat pump system, based on real 1-minute weather data for a particularly cold winter.

We model the UVR16x2 control logic to be implemented, hydraulic details of heat exchangers connected in series (collector, storage tank, heat pump's evaporator), heat transfer to ground, and the varying heating demand of the bulding as well as the COP dependent on external conditions.

Deliverable: A detailed PDF report with monthly and yearly consolidated key data, and plots of daily energy balances, changes of temperatures, and volume of ice. We discuss results in detail and point out which input parameters are particularly critical (Sensitivity analysis).

Digital Certificate (X.509)

Public Key Infrastructure, digital certificates, networking security. Planning, implementation, troubleshooting, and reviews.

Elke Stangl has hands-on PKI experience since 2002; since about 2012 these services have only been offered to long-term PKI clients.

Applications: Data encryption and digital signatures. A digital certificate is the counterpart of an identification badge: The owner possesses a pair of cryptographic keys; the private key can e.g. be stored on a chip card. The public key is part of the published certificate which is signed by a trusted certification authority.

Our speciality: Troubleshooting of the validation of convoluted X.509 certificate paths, and support of Windows PKIs (2000 / 2003 / 2008 / 2012 / 2016).

Manufacturing Execution System: Dialogue Weighing System

Pharma IT - Manufacturing Execution Systems (MES). Analysis of business processes in pharmaceutical manufacturing and mapping of those processes onto the design of IT systems - as an intermediary between production, quality management and software development.

Sigi Proyer has experience in pharmaceutical manufacturing since 1998; these services are only available to long-term clients.

A MES supports: Manufacturing control, control of material flow, production planning, master batch records, electronic batch recording, warehouse management, management of quality status, batch and material tracking.

We support the internal project team with project planning, analysis of requirements, evaluation of products and suppliers - and we lend a hand onsite in critical phases of projects.

Classical small business (probably out of business now)

IT services for small businesses. Also private persons and small businesses have to deal with the increasing complexity of IT-related requirements by governmental agencies or large suppliers. On the other hand, new services offerings are announced every days: Cloud services, e-Government, e-Invoicing, social networks, convergence of building technology and computer networks.

We are also a (very) small business that has met such challenges successfully since many years, and we draw on long-term experience with pragmatic implementation of tough standards in a strictly regulated industry sector. We support you with evaluation of new requirements, restrictions, and opportunities - in terms of 'coaching to the point' as needed.

IT consulting and support is complements our services re programming and troubleshooting of UVR controllers:
