The Privacy Coach is an application running on a mobile phone that supports customers in making privacy decisions when confronted with RFID tags. The approach we take to increase customer privacy is a radical departure from the mainstream research efforts that focus on implementing privacy enhancing technologies on the RFID tags themselves. Instead the… (More)
We report a clinical evaluation of EEG and video monitoring. In 181 consecutive records, the most common clinical indications were differentiation of epileptic and nonepileptic events (99), seizure recordings for locating a possible focus (23), seizure frequency determination (32), and investigation of possible trigger factors (19). Overall, useful… (More)
A requirement for intensive epilepsy monitoring arose from a demand for ictal EEG registration for diagnostic purposes and in the context of pharmacokinetic research. The monitoring facility developed gradually: first conventional EEG equipment was used on the wards, later miniaturized pre-amplifiers were introduced to allow the patient greater freedom,… (More)
Fluorescent tubes flash at twice the mains frequency (100 Hz in Europe). With aging, 50-Hz brightness modulation appears. A survey of tubes used in our institute showed that 42% exhibited brightness modulation up to a depth of 20% or occasionally 30%. The effects of fluorescent lighting on the EEGs of 20 patients with photosensitive epilepsy have been… (More)
A simple analogue system for recognition of spike-wave discharges is described. During an evaluation study of 81 h recording from 23 patients the mean error rates were 4.7% false negatives and 5.2% false positives.
