Abstract: In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.

Abstract: A plant growing structure (100) designed to enhance the root quality, quantity, and architecture of plants grown in plant containers or in the ground is constructed from a plurality of support walls (200). The plant growing structure (100) enhances air circulation to the plant root system (20) to increase root growth and plant productivity. Channels (230) within the support walls (200) are designed with physical structures and materials that be adapted to address issues with aeration, infiltration, drainage, soil structure, root growth, plant nutrient uptake, plant pests and diseases, growing medium moisture, and growing medium microbial content. A liquid permeable drain platform (900) controls the amount and duration of water storage in the growing medium (50). The liquid permeable drain platform (900) may be used as a standalone device or in conjunction with the plant growing structure (100).

Abstract: Techniques are provided for providing assistance to users in locating and accessing points of interest associated with particular time positions in the media items using the techniques described herein. For instance, an electronic device outputting a media item may select one or more metadata items based on a current output position in the media item. The electronic device may then generate and output a user interface including a progress bar that includes indicators representing the selected metadata items and output the user interface to a display of the electronic device.
