The start of an apprenticeship is an exciting time, full of new impressions, challenges, and opportunities for professional and personal development. We are Vivienne, Max, and Lucia, we are in the second year of our training, and we would like to give you an insight into our daily training routine at Jauch. An exciting beginning For the three of us, this exciting time at Jauch began last September.  We were all welcomed in a friendly and reassuring way on our first day, which eased some of our nerves. After a short round of introductions, the onboarding started, during which we were given ..read more

Have you ever wondered why you have to recharge your smartphone battery at increasingly shorter intervals after 1 to 2 years of use? Of course, the phenomenon is not limited to the battery in the smartphone – every rechargeable battery inevitably loses storage capacity over time. But what is the reason for this? And how can the lifetime of a rechargeable battery be determined? The service life of a battery indicates how long the battery can be used in a product before the tolerable loss of performance falls below a certain threshold. These values vary depending on the application. Accordingly ..read more

We know lithium batteries mainly from our smartphones, laptops, or smartwatches: all devices that can be recharged again and again once the battery is empty, but not all lithium batteries are rechargeable. Some chemistries, generally CR (lithium manganese dioxide) and ER (lithium thionyl chloride) batteries, may not be recharged under any circumstances. Both types of batteries are available as button and round cells. CR and ER batteries are used in many applications in homes, including, for example, electronic gas or electricity meters. Nowadays, they are also increasingly being used in the au ..read more

Long lines at the microwave in the university canteen, a short lunch break and then the food also loses its taste and vitamins. For the trio of founders of the start-up Nexenic, this was the reason to revolutionize the topic of Mealprep. The Steasy® founding trio: Johannes Hofer, Claudio Ruiz and Reto Muhl (from left to right) The product: the Steasy® mobile mini-steamer With Steasy®, food can be heated up flexibly on the go. The method is so sophisticated that the food loses neither taste nor vitamins and nutrients. Unfortunately, this is something that has to be accepted when reheating in ..read more

A few people are standing in front of a large whiteboard in the meeting room. The sales department, two OKR Masters and Steffen Fritz, Director Sales and member of the management board, look at colorful index cards on which objectives are noted. Fritz explains the individual objectives while his colleagues from Sales listen intently. Then the discussion starts: what contribution can the team do to achieving the objectives presented? These contributions are then recorded on a second whiteboard. Some meetings are taking place like this or something similar these days, as OKR planning is in full ..read more

Approximately 1 percent of people worldwide suffer from epilepsy. In numbers, that’s one in 100 to one in 150 people. In 30 percent of them, the disease is even incurable. This means that they are unable to control their seizures with the help of medication. Recurrent seizures are the result. “Seizures that occur during sleep are obviously the most dangerous because of the limited ability to monitor them,” explains Danny Reiffers, Product Specialist at LivAssured. According to the ILAE (International League Against Epilepsy), an average of 86 percent of nocturnal seizures go unnoticed. Reiffer ..read more

Let’s start this blog post with a little quiz: Guess for yourself – the solution will come in the text. How thick is a quartz blank of 40 MHz? As thick as.. A: a fingernail B: a normal sheet of printer paper C: one hair Guess for yourself – the solution will come in the text. But first, let’s take a look at the theory: Generally speaking, there is an inversely proportional relationship between the resonant frequency of a quartz blank and the thickness of a quartz plate. In other words – the higher the resonant frequency is to be, the smaller the thickness of this quartz blank required for it ..read more

Lithium batteries are one of the most widely used types of batteries and serve a variety of applications, including electronic devices and energy storage. We know these batteries mainly from our smartphones, wearables, or cars, which we can recharge time and again. However, there are battery chemistries with lithium that cannot be recharged. These include, for example, the lithium thionyl chloride battery (ER types) or the lithium manganese dioxide (CR types). Primary lithium batteries must not be recharged. But why can’t these batteries be recharged? And why is this not a problem with lithium ..read more

It is Monday morning at 9:30 am. A selling order is placed on the exchange. Immediately after, two buying orders arrive for it. But there can only be one buyer. Who was faster and is eligible? How is fairness assured, and guaranteed without any risk of collision? The trading of shares determines the actions on the stock market. The recording of trading events follows strict rules. The compliance of MiFID II organized by ESMA has created these to regulate the functionality of timestamps and therefore full integrity in trading. Figure 1 shows the scenario described above with simplified figures ..read more

Clattering coins, a line of people, and pattering rain: a run-of-the-mill evening scenario in front of a yellow telephone booth. These previously offered the only opportunity to check in with family or friends while on the go. Nowadays, the 140-year era of the telephone booth has come to an end—the smartphone already sealed its fate several years ago. The smartphone has now conquered our everyday lives. Chatting, surfing, making phone calls without having to use coins or wait—the possibilities seem almost limitless. The devices get their energy from lithium cells that can rapidly be recharged ..read more
