The complexity of simulation models has increased during the last years in semiconductor foundries. Manual and automated decisions have to be modeled in detail to make the right conclusions from them. We describe an approach that uses forward simulation to minimize modeling effort and mimics fab behavior to a high degree. The approach is applied to the problem of controlling time link chains. Results...
The continual trend of microelectronics to miniaturization, accompanied by the increase of the power density has given modern science a huge challenge. The thermal transport in an electronic device has to be addressed. Therefore, the fast and precise measurement of thermal properties like temperature, thermal conductivity and diffusivity is needed. Especially the spatial resolution needs to be enhanced...
Sensor networks are becoming popular for applications in private environments such as home monitoring, baby and child monitoring or ambient assisted living. What is often overlooked is the fact that data collected in this context can be very privacy sensitive. This is especially true if images or videos are captured and streamed into the cloud. This work presents a visual sensor network device along...
Visual privacy in video-based applications such as surveillance, assisted living or home monitoring is a highly active research topic. It is critical to protect the privacy of monitored people without severely limiting the utility of the system. We present a resource-aware cartooning privacy protection filter which converts raw images into abstracted frames where the privacy revealing details are...
Images captured in camera networks are potentially privacy sensitive and therefore need protection. A critical aspect is where protection is applied — after transmission at the data center or preferably already on the camera. In this work we take on-camera protection a step further and propose to make privacy protection and security inherent features of the image sensing unit. Already within the camera...
The steady state method is a commonly used and in principle simple way to measure thermal resistance and conductivity of thermal interface materials (TIMs). The sample must be positioned between a hot and a cold plate with constant temperatures, whereby a heat flow through the sample and temperature gradient across the sample are generated. To determine the thermal resistance of the sample the heat...
The steady state method is a commonly used and in principle simple way to measure thermal resistance and conductivity of thermal interface materials (TIMs). A heat flow through the TIM has to be generated and the temperature gradient across the TIM has to be measured. This is also defined by the ASTM standard ASTM D5470 [4]. To generate the heat flow the TIM must be positioned between a hot and a...
Many basic, but very useful features, for characterizing an image or calculating the similarity between two images are based on color information. Psychological studies show that beyond the tone of color, different colors are also associated with different emotions. Thus, two colors that trigger the same impression are most likely considered to be more similar than two colors which trigger the opposite...
Commonly computational methods are used to determine and enhance the lifetime of electronics and electronic systems. The validity of such methods highly depends on the used material data and therefore on the quality of the accompanying experiments. For this reason different methods were combined to better determine the thermal state of a desired device of variable size, while providing this data within...
In traditional video camera networks privacy protection is performed, if at all, at the data center after the video has been streamed over the network. With the on-board processing capabilities of today's visual sensor network devices, image processing and privacy protection can be performed now on the cameras before any data is sent over the network. While moving privacy protection closer to the...
The problem of deterioated automatic speech recognition performance for telecommunication devices like mobile phones is well-studied. However, few papers analyse the influence of emergency broadcast radio devices such as the Terrestrial Trunked Radio (TETRA), which is used for many public safety networks in Europe and Asia. In this paper, we dissect several aspects of the TETRA encoding scheme when...
Increasing functionality in vehicles especially with respect to electromobility is demanding a decrease of energy consumption of numerous board systems. Clustering and miniaturization of sensor applications on the one hand are enabling new features and on the other they are minimizing energy needs for their operation. For modern vehicle driving stability or navigation systems e.g., the SCoM (stacked...
This contribution introduces a new approach for synthesizing discrete process control. In this context, the main focus of this contribution is on a methodology to enhance the synthesis process by application of new structural analysis methods for the used formal modeling language safe Net Condition/Event Systems. These analysis methods are derived from Petri net analysis methods and adapted to the...
Camera networks are used for a variety of applications including surveillance, traffic monitoring or elderly care. The shift from analog towards fully digitized systems has considerably increased their capabilities. With large-scale deployments of smart cameras and visual sensor networks, public awareness of privacy issues is increasing. Researchers are addressing these concerns by introducing privacy...
Visual sensor networks are an emerging research area with the goal of using cameras as pervasive and affordable sensing and processing devices. This paper presents a pervasive smart camera platform which is built from off-the-shelf hardware and software components. The hardware platform is comprised of an OMAP 3530 processor, 128 MB RAM and various interfaces for connecting sensors and peripherals...
