Output optical energy pulses including relatively high energy magnitudes at the beginning of each pulse are disclosed. For this purpose, the invention proposes an electric motor with a first motor part and a second motor part, which interacts magnetically with the first motor part and with respect to which the first motor part is capable of moving in two opposite movement directions. A closing price variation calculation process, responsive to the trade monitoring process, calculates the predicated opening index price of the security index for the beginning of the next regular trading session with respect to a closing index price of the security index at the end of the previous regular trading session. The reflected partial light beams are interfered with the throughgoing partial light beam having an order of diffraction of zero and the thus produced interference patterns are digitized and subtracted from each other, whereby the parallelism of both surfaces of the body can be determined. An indicating element is coupled to the controller to indicate the level of the radio signal to allow the user knows the quality of the background the radio signal. The invention thus relates to the plants, seeds and tissue cultures of the variety CH395417, and to methods for producing a corn plant produced by crossing a corn plant of variety CH395417 with itself or with another corn plant, such as a plant of another variety.
