Abstract: A fluorescence histo-tomography (FHT) method may include capturing, using an imaging device positioned with respect to a chamber of a slicing apparatus, images of a block face of a specimen retained within the chamber. The images may be captured in the visible and infrared or near-infrared spectrum. The method may include co-registering the images to form a combined image, and providing the combined image to an electronic display. In some implementations, the method may include positioning the imaging device away from the chamber, operating the slicing apparatus to expose a second block face of the specimen, and repositioning the imaging device with respect to the chamber.

Abstract: Device for delivering gases for extinguishing fire in an enclosed space. The device comes in a spherical shape, the top and bottom of which respectively have an entry hatch. Each entry hatch is held in place by four keyed cam locks. The device includes spiral bevel gears, a stationary ring and four pinions. Each pinion is responsible for containing/releasing the gases stored therein. Each pinion connects to a cylinder that connects to a cone having slits that allow the gasses to travel in different directions. The device is pitched from outside into the enclosed space or burning room. The device allows first responders with either a timed extension to rescue trapped individuals/things or potentially extinguish a burning room. The device withstands structure fires without becoming damaged. The gases contained inside the device are safe to use in areas populated by humans and are both effective and safe for inhalation.

Abstract: Approaches are described for a client (e.g., an application executing on a computing device) requiring a particular storage format to provide information describing its storage format to a service, such as a multi-tenant computing environment. The service contains data that the client desires to acquire, but in various embodiments, the data on the service is in a different storage format than the format required by the client. The service receives the information describing the storage format and processes the data accordingly, and then provides the processed data to the client in the format required by the client.

Abstract: A service provider network includes a host computer that communicates with a plurality of client devices associated with a user. In order to synchronize the plurality of client devices with respect to content stored within the service provider network, a synchronization service checks to determine if a checkpoint is present within the synchronization service when a request for updated content is received from one of the client devices. If no checkpoint is present in the synchronization service, then content within the user's account may have been updated. If a checkpoint is stored within the synchronization service, then the checkpoint in the synchronization service is compared with a checkpoint in the request. If the checkpoint in the synchronization service is older, content in the user's account has not been updated. If the checkpoint in the request is older, then content in the user's account may have been updated.

Abstract: An adjustable-width saddle includes a frame having a forward end and a rearward end, the rearward end including a laterally extending bridge, and a one-piece shell. The one-piece shell includes a forward end connected to the forward end of the frame, and a split rearward end including a first rider support and a second rider support that are supported at least in part by the bridge. The rider supports are laterally separated from the second rider support by a lateral gap that is adjustable by flexure of the one-piece shell. A lower side of each rider support defines a first channel that receives the bridge. Fasteners extend through one or more slots formed through the bridge and engage the rider supports to fix the gap at a selected width.
