Title: Optical disk driving device
Inventor: HIRATA MASAMICHI
IPC: G11B17/028
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To adjust a clamping force applied to an optical disk freely variable from an outside. SOLUTION: This optical disk driving device is provided with a laminated piezoelectric body 12 for applying a pressing force to a chucking pulley 4 holding an optical disk 6 with a turntable 3 according to a voltage applied from the outside. The laminated piezoelectric body 12 is composed by alternately laminating a piezoelectric element 21 made of a crystal distorted at the time of receiving a voltage, and an insulator 22. When the optical disk 6 is rotary- driven at a high speed, the flow of air generated following the rotation of the optical disk 6 gives a flying force to the optical disk 6. However, a chucking force to counter such the flying force is pressed via the laminated piezoelectric body 12, and thus the floating of the optical disk 6 is prevented.

Abstract: PURPOSE:To improve band limitation effect in a slanting direction by employing the basic constitution structured by stacking a birefringent plate which separates luminous flux at 45 deg. of a horizontal axis and birefringent plates which separate luminous flux horizontally and vertically. CONSTITUTION:The Savart plate S11 which separates the luminous flux at 45 deg. to the horizontal axis, Savart plate S12 which separates the luminous flux horizontally or vertically, and Savart plate S13 which separates the luminous flux at right angles to the luminous flux separation of the Savart plate S11. The angle between the luminous flux separation directions of the Savart plates S11 and S12 is 45 deg., so two pieces of luminous flux separated by the Savart plates S11 and S12 are separated in 1:1 light intensity proportion into four pieces of luminous flux, and the number of pieces of luminous flux passed through the Savart plate S13 is eight. Thus, sufficient band limitation effect is obtained even in the slanting direction, so components with low importance to the human eyes are removed, so that natural reproduced images are obtained when this filter is applied to a solid-state image pickup device, etc.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of this power converter, by detecting the trouble of a main switching element and a snubber circuit, and by monitoring the voltage and current of a snubber circuit part for inhibiting overvoltage and an overcurrent connected to the main switching element. SOLUTION: The voltage of a snubber diode 11 reaches zero voltage when one of a GTO 8, a by-passing diode 9 and a snubber capacitor 12 gets trouble and is short-circuited, and voltage reaches zero when snubber diode 11 itself gets trouble and is short-circuited. When the resistor of a snubber resistor 10 is disconnected, the voltage of the snubber capacitor 12 is left as it is charged up to DC voltage, and the voltage of the snubber diode 11 as a difference section with power-supply voltage is not increased up to power-supply voltage. Consequently, the short circuit of the snubber diode 11 and the disconnection of the snubber resistor 10 can also be detected in addition to each short circuit of the GTO 8, the by-passing diode 9 and the snubber diode 12 by monitoring the voltage of the snubber diode 11 by a voltage detector 21.  Accordingly, the reliability of a power converter can be maintained.

Title: Method for fast determining of vehicle movement speed and device with amr sensors implementing it
Inventor: VALINEVIČIUS ALGIMANTAS
IPC: G08G1/00
Filed: 2018-02-09
Abstract: When measuring the vehicle speed with two magnetic sensors, the time difference between dependencies measured by two different sensors (magnetic signatures, signatures) is determined. The higher the number of points in the signature, the more accurate information can be obtained from measurements. On the other hand, a high number of points lengthens the processing time and increases the energy consumption for computations. When it is necessary to accurately identify a vehicle that exceeds the set speed, the data must be processed extremely fast to allow the capture camera (or other vehicle identification means) to capture the offender. This invention provides a new fast method for determining the speed and device implementing it. The method for determining the speed uses the difference of “mass centres” as the initial information for computing the cross-correlation coefficient. Then, the cross-correlation coefficient maximum is searched using a set of shifts, the centre of which is the difference of “mass centres”. The computation method provided not only shortens the computation time, but also allows more efficient use of the energy used by the speed meter .In addition, using two speed meters (having vehicle identification means) arranged at a known distance, the average vehicle speed on the stretch between these two meters can be determined.
