Abstract: Acoustic medium of ultrasonic grip system consists of piezoelectric generator (1), wheel knuckle (9), ball bearing (10), wheel hub (11), wheel rim (15) and tyre of motor-car (20). The piezoelectric generator (1) creates ultrasound vibrations which are transferred through the acoustic medium to the surface of tyre (17). The ultrasound vibration on the surface of tyre (17) results in the separation of the surface of tyre (17) from the liquid (18) that may be found on tarmac (19) during the rain, which results in the fact that despite the unfavourable weather conditions the motor-car has an optimum rolling surface of tarmac. Also, the vibrations on the surface of tyre (17) in interaction with micro texture of tarmac increases the contact surface of tyre with tarmac, which results in the increase of coefficient of friction, higher grip of tyre and reduction of braking distance of motor-car. The ultrasonic grip system is activated at sudden braking, resp. activation of ABS system.

Abstract: An image forming apparatus that has an image bearing member to be removably mounted to the image forming apparatus includes an intermediate transfer member, a toner detection unit, an exposure device, a forming unit, and a judgment unit.

Where the toner detection unit detects the first and second patterns of toner images, the judgment unit judges that the image bearing member is mounted. Where one of the first and second patterns is not detected, the judgment unit judges that the image bearing member is not mounted.

Abstract: Various lens designs for use in Time of Flight (ToF) sensor systems are discussed. Improvements to a ToF sensor system may be realized by, for example, incorporating a lens having particular features, such as a relatively short track length, fast lens speed (e.g., low f-number), low telecentricity, relatively flat field illumination, and fairly low cost. In some examples, such a lens of a ToF sensor system may be a lens assembly having a fixed focal length and that avoids use of lenses having aspheric surfaces so as to achieve relatively low cost.
