A phase change material, including multiple phase change materials of different formulations, is placed in heat transfer association with an electronics enclosure (e.g., a sealed enclosure) deployed in an environment that causes the electronics and the phase change material to experience periods of heating and periods of cooling. During the periods of heating, the phase change material absorbs heat and changes at least partially from a first state to a second state to maintain the temperature of the electronics at a desirable level. During the periods of cooling, the phase change material reverts at least partially back to the first state for future heat absorption. The phase change material is cooled by a thermally cooler body such as the night sky. The electronics enclosure and phase change material may be placed in a second enclosure covered with a paint having a paint additive that reflects solar radiation.

In order for the feature extractors to operate with sufficient accuracy, a high degree of training is required. In this situation, a neural network implementing the feature extractor may be trained by providing it with images having known correspondence. A 3D model of a city may be utilized in order to train a neural network for location detection. 3D models are sophisticated and allow manipulation of viewer perspective and ambient features such as day/night sky variations, weather variations, and occlusion placement. Various manipulations may be executed in order to generate vast numbers of image pairs having known correspondence despite having variations. These image pairs with known correspondence may be utilized to train the neural network to be able to generate feature maps from query images and identify correspondence between query image feature maps and reference feature maps. This training can be accomplished without requiring the capture of real images with known correspondence. Capture of real images with known correspondence is cumbersome, time and resource-intensive, and difficult to manage.

An image obtained when a rare or valuable thing is found is shared between users each wearing an image display apparatus on the head or face.

When a man finds a rare or valuable thing, the man feels like telling it to his/her surroundings. For example, when the man finds a planet such as Venus or shooting stars in the night sky, fish or a fresh water crab in a pond or a river, a bird, a cicada, a unicorn beetle, or the like on a tall tree in the woods, the man feels like saying “Look there!” An image display apparatus 100 releases a captured image in a line-of-sight direction of the user to share a user's precious experience with other users.

To enable legal twenty-four hour national flag display, to permit night display of vehicle-mounted school and team flags, and to do either with minimal increase in night sky light pollution, I mount a light source immediately adjacent a flag and direct the light essentially directly toward the flag, rather than upwardly into the sky. Preferably, the light source is provided within a transparent portion of the flag-mounting pole, and is ideally focused directly toward the flag by a reflector which is adapted to shift positions with changes in flag positions due to directional changes of air flow across the flag.
