Abstract: Methods and devices for managing output devices in a vehicle are disclosed. Data is obtained representing a sensed position of the first vehicle and a sensed feature in a proximity of the first vehicle. A first probability density function (PDF) is defined based on the obtained data, representing likelihood of a future position of the first vehicle. A second PDF is defined based on the obtained data, representing likelihood related to a proxemic risk presented by the sensed feature. A risk metric is computed representing a likelihood of the proxemic risk to the first vehicle based on an overlap between the first PDF and the second PDF. A useable number of information bits is determined, based on the risk metric. An application is controlled to provide output, via output device(s) of the first vehicle, within the useable number of information bits.

Abstract: Methods and devices for managing output devices in a vehicle are disclosed. Data is obtained representing a sensed position of the first vehicle and a sensed feature in a proximity of the first vehicle. A first probability density function (PDF) is defined based on the obtained data, representing likelihood of a future position of the first vehicle. A second PDF is defined based on the obtained data, representing likelihood related to a proxemic risk presented by the sensed feature. A risk metric is computed representing a likelihood of the proxemic risk to the first vehicle based on an overlap between the first PDF and the second PDF. In response to the risk metric exceeding a defined risk threshold, at least one haptic output unit in the first vehicle is controlled to provide haptic output indicative of the proxemic risk.

Abstract: This invention describes a method for preparing polymethoxymethylal. By this method, polymethoxymethylal is prepared by a catalytic reaction using methanol and trioxymethylene as reactants and using an ionic liquid as catalyst under a relatively moderate reaction condition. The catalyst of this invention has a high catalytic activity and a high conversion; the reaction process is simple, easy to be operated and has a strong controllability; the distribution of the products after reaction is superior and the utilization ratio of the raw materials is high.
