This paper is focused on a novel design of stepped diaphragm for MEMS capacitive pressure sensor used in tire pressure monitoring system. The structure of sensor diaphragm plays a key role for determining the sensitivity of the sensor and the non-linearity of the output.First the structures of two capacitive pressure sensors with clamped square flatdiaphragms, with different thicknesses are inv...

This article presents an overview on the state of the art of Tyre Pressure Monitoring System related technologies. This includes examining the latest pressure sensing methods and comparing different types of pressure transducers, particularly their power consumption and measuring range. Having the aim of this research to investigate possible means to obtain a tyre condition monitoring system (T...

Wireless autonomous sensor systems become steadily standard components in our environment and they become smaller, cheaper and more sophisticated. Energy harvesters fabricated by micro-system technology can realize the autonomy of those systems. An overview of latest results and remaining challenges will be given with the focus on vibration energy harvesters. These harvesters are of specific in...

Military fighter pilots have to function in environments that unavoidably have an effect on both production and reception of speech. Speech production is affected by for example g-forces, positive pressure breathing (PBG), background noise and workload. This can have an effect on the understandability of speech, which in turn can affect flight safety. This study seeks to analyse the changes in ...

This paper deals with the interface-relevant activity of a vehicle integrated intelligent safety system (ISS) that includes an airbag deployment decision system (ADDS) and a tire pressure monitoring system (TPMS). A program is developed in LabWindows/CVI, using C for prototype implementation. The prototype is primarily concerned with the interconnection between hardware objects such as a load c...

Preventing pressure ulcers (PUs) in an acute hospital setting is a complex activity. It clearly sits within the definition of implementing complex care to a complex group of patients in a complex setting (Raine et al, 2016). The multiple comorbidities and increased acuity of the at risk patient result in many conflicting care priorities. In addition there are many changes in healthcare provisio...

Pediatric neurosurgical patients present a unique set of anesthetic challenges that include treatment of increased intracranial pressure (ICP), the use of positions other than supine, and the anesthetic implications of neurophysiologic monitoring. These and other general considerations are addressed in the first part of this chapter, followed by a discussion of anesthetic techniques for common ...

Slow waves in intracranial pressure (ICP) and related signals seems of interest to evaluate the dynamic autoregulation, i.e. by comparison of the frequency links between an intracranial signal, e.g. ICP, cerebral blood velocity (CBV), and arterial blood pressure (ABP). To clarify the links, we compared two frequency methods based on coherence function to estimate the influence of ICP, ABP and C...
