A slide switch includes a case forming an accommodation space, a first contact disposed in the accommodation space, a second contact disposed in the accommodation space, a third contact disposed in the accommodation space, and a slider fixed to the third contact. The slider is movable between a first position in which the first contact and the second contact are electrically insulated from each other and a second position in which the first contact and the second contact are electrically connected to each other via the third contact. The case includes a projection supporting the third contact in a normal direction of a plane which includes a moving path of the slider in the accommodation space.

A data processing apparatus acquires images captured by cameras. A data processing apparatus 2 calculates relative positional relationship between the camera that captured an image and a camera that is captured in the captured image, by image recognition of the captured image. The data processing apparatus 2 aggregates positional relationships calculated for the captured images, respectively, and by having one camera as reference, calculates the relative positions and directions of other cameras. Based on the calculated results, a user interface for supporting selection of the captured image by a user is generated.
摘要:
Provided is a technique capable of accurately calculating the radiation power of an object to be measured using a spheroidal coupler even when there is a non-negligible loss in a measurement system.A phase rotating unit including a variable phase shifter, a two-branch circuit, and a reflective element that is connected to one of the branched outputs of the two-branch circuit is inserted between a receiving antenna and a power measuring device. The maximum value and the minimum value of power measured by a power measuring device when the variable phase shifter changes a phase are calculated. An output reflection coefficient of a coupler is calculated from the ratio of the maximum value to the minimum value, and an input reflection coefficient of an object to be measured which is approximate to the output reflection coefficient is estimated. In addition, an input reflection coefficient of a reference antenna which is used instead of the object to be measured is estimated in the same way. The total radiated power of the object to be measured is calculated on the basis of the estimated input reflection coefficients and the reception power when the power measuring device directly measures the output of the receiving antenna.
