Abstract: An optical scanner includes a light source, an optical phased array, a monitoring light receiving unit, and a signal processing unit. The optical phased array implements scanning by a light beam by individually controlling phases of a plurality of branched lights into which light supplied from the light source is branched, using a scanning phase amount, and radiating light from an antenna array that has a plurality of antenna elements. The monitoring light receiving unit receives light radiated from the optical phased array. The signal processing unit detects characteristics of the light beam from a detection result of the monitoring light receiving unit and generate a phase adjustment amount for correcting the scanning phase amount such that a detection value of the characteristics coincides with a design value prepared in advance.

Abstract: An optical scanner includes a light receiving unit, a reference light irradiating unit, and a light-receiving-side correcting unit. The light receiving unit includes an optical phased array that implements scanning by a light beam by individually controlling phases of a plurality of branched lights using a scanning phase amount. The reference light irradiating unit generates reference light and irradiate the reference light onto the light receiving unit. The light-receiving-side correcting unit estimates a phase shift amount that occurs in the plurality of branched lights as a result of distortion of a substrate on which the light receiving unit is mounted from a detection result of the light receiving unit onto which the reference light is incident, and sets a phase adjustment amount to be applied to the plurality of branched lights such that the estimated phase shift amount decreases.

Abstract: A LIDAR device performs an emission process of emitting the laser light to surroundings of a vehicle. The emission process includes a scanning process and a resolution adjustment process. The scanning process includes a process of scanning with the laser light a predefined direction that is one of vertical and horizontal directions. A plurality of emission directions include, as four directions, a first direction and a second direction adjacent to each other in the predefined direction, and a third direction and a fourth direction adjacent to each other in the predefined direction. The resolution adjustment process includes a process of making an angle difference between the third and fourth directions less than an angle difference between the first and second directions, and a variably setting process of variably setting the angle difference between the third and fourth directions according to a state variable of the vehicle, as an input.

Abstract: An optical transmission apparatus includes: a wavelength selecting switch, including an input port and an output port having more ports than the input port, configured to perform an adjustment of a level of an optical signal from the input port to the output port; a first monitor configured to monitor the level of the optical signal at the input port unit; a second monitor configured to monitor the level of the optical signal at the output port unit; and a controller configured to control the wavelength selecting switch wherein the controller: calculates a virtual output value for the output port unit based on a first monitor result from the first monitoring unit, a second monitor result from the second monitoring unit, and a current adjustment value for the adjustment function; calculates a new adjustment value based on the virtual output value; and sets the new adjustment value to the adjustment.

Abstract: When a user outputs, e.g., a plurality of sheets of a content by printing the contents of a variable part in page data to be automatically edited is automatically edited/outputted for each customer by using customer data, a marketing database, and so on. A user terminal is provided with an automatic editing system for page data. In a database system connectable with the user terminal, stored is data on relation about what content is arranged on the variable part in the page data when the page data is outputted. The user terminal designates a layout of the page data, acquires data for automatically selecting and outputting a content by accessing a content database in accordance with the relation, creates page data according to the layout, and outputs it. During the processings, a content arranged in the variable part is automatically selected and inserted for every output in accordance with the relation.

Abstract: Retrieving content from distributed content servers and using the content to perform charging and register the content in a content server.

Abstract: Performing protection of content and appropriate charging at the time of using the content according to a method of use.

Abstract: A user carries out charging processing at the time when he/she downloads or outputs a content, and also carried out the charging processing in accordance with the size, resolution, output method, etc. of the content when the charging is carried out.

Abstract: There is provided a program that is used for charging when contents are used and installed in a user terminal.
