Rearing, lead response

UC of sub-band gap photons for a conventional single-junction bifacial solar cell was presented by Trupke et al. in 2002 [44]. The upconverter, consisting of Er " -doped NaYp4, was located on the rear side of a bifacial cell, thus leading to a response of the cell when it was excited at 1500 nm. From then on, significant improvement, including both theoretical analysis and experimental achievements, has been reported in the field of solar UC. According to the literatures, UC is predicted to enhance the efficiency of solar cells when mounted on the rear of the solar cell [45, 46]. 

This measure can quickly lead to a high ASIL because rear axles are responsible for stabilized driving of the vehicle. 

The most important cue that a driver has to indicate that the car ahead is braking is the onset of its brake lights. Regrettably, that cue may sometimes arrive too late, in the sense that by the time the following driver realizes that the car ahead is braking, he or she does not have enough time to brake in order to avoid a rear-end collision. The most dramatic and extreme situations of that type are the chain accidents on the high-speed freeways. The question is, is there a way to speed up that realization so that we can brake more rapidly in response to the lead car s deceleration ... 

The second series of studies was designed to evaluate an iimovative approach to reduce rear-end crashes by reducing the lag time between the lead driver s decision to brake and the response of the driver behind that car. Thus, the following driver would respond to the lead driver s decision rather than motor response to that decision. The concept behind the particular...
