Sensors detect an input event and control an output event. The output often requires different timing than that of the input event. Sometimes several inputs must jointly produce an output event. In other words, logic alters the raw sensor signal so that it is directly useful for controlling local action in response to sensed events (Ouzounov et al., 2006). A sensor is an interactive application; it expresses interest in an event by defining a sensitive ‘region' and an event type. For example, if a sensor wishes to receive events directed to a geographical object, it can define its region ...

Lie Detector

Beginning of Lie detector For around centuries, individuals searched various approaches to exposing liars, looking for clues in the blushing cheeks, tricky eyes, twisting toes and all other body's outward signs. However, this finally reached its initiation in the 1920s, when a police officer with a PhD collaborated with an entrepreneurial secondary school student of Berkeley, California and asserted to have developed a machine that researched straightforwardly inside the human heart. In a couple of years, their machine altered police work, detained headlines, tackled mysterious murders and captivated the country. The concept of using a lie detector rose emerged in the middle period ...

A polygraph test measures the pulse, blood pressure, respiration, perspiration and skin conductivity of a test subject, in the belief that the telling of a truth or a lie has an effect that manifests in these physiological indices. Throughout its history and since its invention, the polygraph has enjoyed claims of up to 90% accuracy from its advocates. However, the accuracy of the polygraph has widely been criticized as there is not enough evidence to support these claims. Further, research shows that most studies carried out to establish the validity of the polygraph do not meet scientific standards of quality and rigor. ...

Human factor is the major challenge that stands on the way of the specialists in the field of criminal law.
