Keyboard-based search of local and/or connected digital media items may be facilitated. A digital media item search interface may be presented in the same view as a messaging interface. The digital media item search interface may receive input such as from an on-screen keyboard to facilitate editing of user-provided search queries and submission of the user-provided search queries. The digital media item search interface may present digital media item tags relating to context information based on input received by the digital media item search query field. The digital media item search interface may present visual previews of local and/or connected digital media items corresponding to digital media item tags presented in the digital media item tag field. The digital media item search interface may receive user selections of individual digital media items to be communicated to one or more other users via the messaging interface.

Provided are implantable or surface mounted biomedical devices and related methods for interfacing with a target tissue. The devices have a substrate and device component supported by the substrate. The components of the device are specially configured and packaged to be ultra-thin and mechanically compliant. In particular, device thicknesses are less than 1 mm and have lateral dimensions between about 1 μm and 10 mm, depending on the application. Delivery substrates may be incorporated to assist with device implantation and handling. The devices can be shaped to provide injection in a minimally invasive manner, thereby avoiding unnecessary tissue damage and providing a platform for long-term implantation for interfacing with biological tissue.
摘要:
A traveling wave nuclear fission reactor, fuel assembly, and a method of controlling burnup therein. In a traveling wave nuclear fission reactor, a nuclear fission reactor fuel assembly comprises a plurality of nuclear fission fuel rods that are exposed to a deflagration wave burnfront that, in turn, travels through the fuel rods. The excess reactivity is controlled by a plurality of movable neutron absorber structures that are selectively inserted into and withdrawn from the fuel assembly in order to control the excess reactivity and thus the location, speed and shape of the burnfront. Controlling location, speed and shape of the burnfront manages neutron fluence seen by fuel assembly structural materials in order to reduce risk of temperature and irradiation damage to the structural materials.

摘要:
A method of performing a retinal examination is described wherein perimetry points are selected in three dimensional imaging data of the retinal tissue. The corresponding points in register with these perimetry points are mapped to an en-face image. These corresponding points are used as stimulus locations for a micro-perimetry examination.
摘要:
A rapid doffing and donning vest uses a clam shell design wherein the ends of the cummerbund are removably attachable to the rear panel. A blade on the cummerbund mates with a receiver on the rear panel and has a plunger hold the two together. The plunger is attached to a pull strap located on the front panel's shoulder strap via a cord. As the pull strap is pulled outwardly, the cord pulls the plunger away from the mated blade and receiver and allows the two to decouple detaching the cummerbund from the rear panel. Outward pulling on the pull strap also facilitates decoupling of the shoulder strap from the rear panel. When the vest is doffed, the front panel and cummerbund remain attached to each other and detached from the rear panel.
