A method for controlling an electronic device includes providing as part of the electronic device a display screen for displaying content and a sensing assembly including at least one photoreceiver and a plurality of phototransmitters, wherein each phototransmitter is positioned to emit infrared light away from the electronic device about a corresponding central transmission axis, wherein each central transmission axis is oriented in a different direction with respect to the others. Emission of infrared light by each of the phototransmitters is controlled during each of a plurality of time periods as an external object moves in a first specified pattern of movement and then moves in a second specified pattern of movement which is offset from a generally centered position with respect to the sensing assembly, and measured signals are generated. The measured signals are evaluated to identify the first specified pattern of movement of the object, to detect a reference offset location corresponding to an end of the first specified pattern of movement of the object, and to determine, for each of a group of time periods when the object is moving in the second specified pattern of movement, a corresponding location of the object during that time period. A centering operation is performed in response to the identification of the first specified pattern of movement, wherein the centering operation moves an indicator to an initial predetermined reference location on the display screen, wherein the predetermined reference location is then associated with the reference offset location; and sequential locations of the indicator on the display screen are controlled in accordance with the corresponding determined locations of the object relative to the reference offset location.

A novel class of optoelectronic devices incorporate an interference filter. The filter includes at least two optical cavities. Each of the cavities localizes al least one optical mode. The optical modes localized at two cavities are at resonance only at one or at a few discrete selective wavelengths. At resonance, the optical eigenmodes contain one mode having a zero intensity at a node position between the two cavities, where this position shifts as a function of the wavelength. A non-transparent element, which is preferably an absorbing element, a scatterer, or a reflector, is placed between two cavities. At a discrete selective wavelength, when the node of the optical mode matches with the non-transparent element, the filter is transparent for light. At other wavelengths, the filter is not transparent for light. This allows for the construction of various optoelectronic devices showing a strongly wavelength-selective operation.

The invention comprises a survey pole having a survey pole bottom end, with a position-transducer coupled to a survey pole top end. A ground contact spike is on the bottom end. The survey pole uses an AINS as a combined tilt and heading sensor. The AINS provides heading and Euler angle outputs characterizing the tilt of the survey pole. The heading and Euler angle outputs are used by a computer and program to perform position transfers from a position-transducer at the pole top end to the GCZVI switch or spike on the ground using a set of position offset or transfer equations. The position-transducer is either a GNSS or an RTS serving as a position-transducer. The transfer of the position data from the position of the position-transducer provides the earth referenced or grid referenced position of the spike at the survey pole survey bottom end.

A plurality of patterns respectively having different area factor of dot formation area are formed by forward and reverse scanning printing of a print head, and then optical characteristics of the plurality of formed patterns are measured. A function representing the relationship between the printing position offset between the forward and reverse printings is determined from the optical characteristics.

By applying this measured optical characteristics to the function, an adjustment value of the dot formation position conditions between the forward and reverse scans is obtained for each mode. This makes it easy to perform printing registration in a printing apparatus in the case of printing by a forward and reverse scan of a printing head or in the case of printing by means of a plurality of printing heads. In this case, operations by a user etc. are also unnecessary and are easily performed.

By use of charged particle beam images picked up in different conditions, a positional displacement caused by parallax is analyzed, and an optics of an apparatus for charged particle beam microscopy is corrected automatically. An analysis method using phase difference of Fourier transform images and having analytic accuracy lower than that for one pixel is adopted for the displacement analysis. In addition, a degree of coincidence between images calculated in this analysis method is used as a criterion for evaluating the reliability of an analysis result. Since the analysis method based on parallax is low in specimen dependency, the operation range is expanded. In addition, by adopting a high-accuracy displacement analysis method, the apparatus correction accuracy is improved by one digit. A malfunction preventing flow is added using the degree of coincidence as a judgement criterion. Thus, the apparatus can deal with unmanned operation. In addition, the degree of coincidence can be used as a monitor of inspection states or a record of states in an inspection apparatus.
