摘要:
A digital still camera for receiving a optical tape cassette having optical tape including an image sensor for capturing an image; focusing an image of a subject onto the image sensor which in response thereto captures such image; a structure for receiving the optical tape cassette; an optical writer for effecting a change in the optical properties of the optical tape. The optical tape is movable into operative relationship with the optical head; the image sensor and the optical writer causes the optical head write to effect changes in the optical properties of the optical tape in accordance with the image captured by the image sensor.

A display for presenting selected images to a viewer is disclosed, including a transparent substrate, a transparent, electrically conductive coating formed over the transparent substrate, a light modulating layer formed over the transparent, electrically conductive layer and a photosensitive layer formed over the light modulating layer which is adapted to be exposed and developed to provide viewable and conductive images. The display further includes the light modulated layer being effective in two conditions, in a first condition to prevent the viewing of the viewable and conductive images and in a second condition to permit the viewing of the viewable and conductive images, and an electrical conduction structure connected to the viewable and conductive images and the transparent, electrically conductive coating for applying a field to the selected ones of such viewable and conductive images to cause the light modulating layer to change from the first condition to the second condition so as to present such viewable and conductive images to the viewer.
摘要:
A portable battery powered printer for printing images from an image source is disclosed. The image source can be a computer for storing a digital image and defining an opening. The printer is sized so as to be insertable into the image source opening and having a rechargeable battery. When the printer is connected to the image source it can be recharged and receives image data from the image source. The printer includes a device for printing an image from the received image data.

A display for presenting image forming light to a viewer, includes a transparent substrate; a transparent, electrically conductive layer formed over the transparent substrate; a light modulating layer formed over a portion of the transparent, electrically conductive layer being effective in a first stable state to reflect light and in a second stable state to transmit light; and a layer formed over the light modulating layer which includes separate conductive portions. Electrical connections are provided which are selectively connected to separate conductive portions and being effective in a first condition to apply a first field across selected portions of the light modulating layer which correspond to separate conductive portions to be in the first stable state to reflect light and to apply a second field across selected separate conductive portions of the light modulating layer which correspond to separate conductive portions to be in the second stable state to transmit light.

摘要:
A compact flash lamp array includes a housing defining a plurality of cavities. Each cavity has a light emitting opening and a primer vent opposite the light emitting opening. A combustible mass is deposited in each cavity over the primer vent and a primer mass is deposited on the outside of the housing over each primer vent. A primer is cover secured over each primer mass, and a sheet of transparent material is bonded over the cavities in the housing.
摘要:
A compact flash lamp array includes a housing defining a plurality of cavities, with each cavity having a light emitting opening and a combustible mass deposited in each cavity. A firing means such as an electrically heated filament or percussive primer is provided for individually firing the combustible mass in each cavity. Each cavity in the housing is provided with a porous portion communicating to the outside of the cavity having sufficient porosity to maintain cavity integrity during combustion of the combustible mass contained in a cavity while retaining combustion by-products.
