Abstract: An example hydraulic tool includes: a fluid reservoir; a pump; an electric motor; a cylinder; a piston; a first trigger button; a second trigger button; and a controller configured to perform operations comprising: receiving a first signal when the first trigger button is triggered, responsively, causing the electric motor to rotate in a first rotational direction, thereby: (i) causing the pump to provide fluid to the cylinder, and (ii) causing the piston to move in a first linear direction, thereafter, receiving a second signal when the second trigger button is triggered, and responsively to the second signal, causing the electric motor to rotate in a second rotational direction opposite the first rotational direction, thereby: (i) opening a fluid path from the cylinder to the fluid reservoir, and (ii) causing the piston to move in a second linear direction opposite the first linear direction.

Abstract: A turbocharger for an internal combustion engine or fuel cell includes a compressor having a liquid-cooled backplate through which a liquid coolant is circulated. The backplate reduces compressor outlet temperature, thereby reducing the cooling load on the intercooler for the engine, and enabling a reduction in charge air temperature entering the engine air inlet manifold. The compressor can include a serial two-stage compressor, in which case the backplate serves as a divider between the two impellers. In another variation, a turboexpander is combined on the same shaft with a single-stage compressor having the liquid-cooled backplate. Pressurized air from the compressor drives the turbine wheel of the turboexpander, expanding and reducing the temperature of the air before being fed to the engine.

Abstract: Methods and apparatuses for automated software container rehydration and deployment include a server that updates a container image for a software application by modifying layers of the container image and deploying the updated container image as a first container in a passive production environment. For a plurality of traffic volumes, the server: a) increases application traffic directed to the first container to a first traffic volume, b) monitors service level indicators associated with performance of the first container, c) increases the application traffic directed to the first container to a higher traffic volume upon determining that the service level indicators are within a performance threshold, and d) repeats steps b) and c) until the application traffic is increased to a highest traffic volume and the service level indicators are within the performance threshold. The server deploys the updated container image as a second container in an active production environment.
