A passive solar heating model for studying the daylight illumination of a lot containing buildings and trees comprises a platform, a pair of arms pivotally mounted at one end thereof to the opposite sides of the platform, and an arcuate guide track pivotally mounted to the free ends of the arms for supporting a light source. The pivotal arms allow adjustments to account for the latitude corresponding to the parallel on which the lot is located and the pivotal guide track allows adjustments to accommodate for the time of the year to be studied. Finally, the light source is movably mounted on the track allowing for time-of-the-day adjustments.
A measurement device comprising a horizontal track, at least one self-leveling foot coupled to the horizontal track, a hemispherical track coupled to the horizontal track, a movable sensor unit coupled to the hemispherical track, and a connector disposed on the hemispherical track for taking measurements on the ground.
An apparatus for use with a source of light including a first orientation device that includes a latitude scale, a latitude pointer rotatable about a first axis relative to the latitude scale, and a platform configured to support an architectural model. The platform is mounted on the latitude pointer such that rotation of the pointer about the first axis produces a corresponding change in the position of the platform relative to the latitude scale. The apparatus also includes a second orientation device that includes a time scale and a time pointer rotatable about a second axis relative to the time scale. The first orientation device is mounted on the time pointer such that rotation of the time pointer about the second axis produces a corresponding change in the position of the platform relative to the time scale without changing the position of the platform relative to the latitude scale. The apparatus further includes a third orientation device that includes a day of the year scale, a gnomon operatively oriented relative to the day of the year scale, and a universal joint supporting the third orientation device for movement relative to a source of light. The second orientation device is mounted on the third orientation device such that movement of the third orientation device on the universal joint produces a corresponding change in the position of the platform relative to the source of light without changing the position of the time pointer relative to the time scale or the position of the platform relative to the latitude scale.
A system of analyzing and processing images. The image is processed using machine vision techniques to find shapes and objects in the image. In one embodiment, the system finds geometric shapes and textures in the images. In another embodiment, the image processor finds actual objects in the image. Each of these items may be replaced with an indication of the item, along with difference information indicating the difference between the actual object in the image, and the object stored in the database. The difference information may include scale information, rotation information, color information and others. The information in the database may also include sub indicia, such as information about different parts of the item, and/or information about other things that may exist in the image.
