Abstract: A grinding wheel includes a plurality of wheel tips. The plurality of wheel tips include a plurality of diamond abrasive grains and a bonding material mixed with the diamond abrasive grains. The plurality of diamond abrasive grains have a ratio of a length in a long axis direction to a width in a short axis direction of 1:2.5 to 1:3.5 and includes edges or vertices having a grinding angle of 90° or less.

Abstract: A smart driving posture control system includes: an image sensor installed in a vehicle, a memory for storing instructions, and a processor connected to the image sensor and the memory. The processor recognizes a user boarding the vehicle through the image sensor to extract human body feature information of the user, extracts recommended posture information based on the extracted human body feature information, and controls a convenience device based on the recommended posture information to adjust a driving posture of the user.

Abstract: An electric charge fee calculation and collection system for an electric vehicle includes a charge control unit that receives power from a power supply means and charges a battery of the vehicle; a power usage amount and cost calculation unit that measures a power usage amount supplied to the battery from the power supply means and calculates an electricity rate corresponding to the measured power usage amount; and a collection means that collects the electricity rate from a user.

Abstract: A posture control apparatus is provided. More specifically, a memory stores positional information of a seat corresponding to a sex, a stature, a sitting stature and a body type of a driver. An information collector receives the sex, the stature, the sitting stature and a weight of the driver and a sitting stature section determinator determines a sitting stature section of the driver based on the received stature and sitting stature of the driver. A Body Mass Index section determinator determines a body type section of the driver based on the received sex, stature, and weight of the driver. A controller then determines a position of the seat corresponding to the sex, the stature, the sitting stature section and the body type section of the driver based on the positional information of the seat stored in the memory.

Abstract: Disclosed is an eye breakaway prevention system for use while driving a vehicle. More particularly, the eye breakaway prevention system allows a driver to operate or monitor the functions of a vehicle without diverting their eyes from the area in front of the vehicle (i.e., the direction of the road) when selecting one or more functions or checking the side mirrors and the dashboard while driving. The eye breakaway prevention system during vehicle's driving includes a function selection unit that is disposed on a steering wheel in a vehicle, selects a corresponding function and operation in accordance with an operation by a driver's finger, and outputs a corresponding signal. A control unit controls the function and operation selected by the driver in response to the signal output from the function selection unit; and a function performing unit performs the function corresponding to a control signal outputted from the control unit.
