Abstract: In a de-icing and washing device and method of a vehicle, a heating module is in liquid communication between the main tank and a nozzle. The control module is communicated with the pump, the wiper and the heating module, and operated in an automatic mode for activating the heating module to heat the washing liquid therein and automatically starting the pump when the temperature of the washing liquid in the heating module is ranged from a first preset value to a second preset value. In such manner, the washing liquid in the main tank is introduced into the heating module, heated by the heating module and sprayed through the nozzle.

Abstract: An electronic scale includes a weighing unit coupled to a processing unit. A data memory device is coupled to the processing unit and stores a list of diseases and associated constraints of food consumption. The user may establish personal constitution feature data in the memory and associates the personal constitution feature data with one or more diseases in the disease list. The memory also stores nutrition/calorie data of a number of different categories of foods as a food list. When a particular food is being weighed, the user may select the category of the food in the food list and the processing unit performs calculation of the nutrition/calorie of the particular food. A warning is issued if the user's personal constitution feature data indicates that such an amount of nutrition/calorie is not acceptable to the user for health purposes. Electrodes are coupled to the processing unit for measuring and calculating body fat of the user.
