Flowing electrolyte fuel cell with improved performance and stability
A flowing electrolyte fuel cell system design (DHCFC-Flow) is provided. The use of a flowing oxygen-saturated electrolyte in a fuel cell offers a significant enhancement in the cell performance characteristics. The mass transfer and reaction kinetics of the superoxide/peroxide/oxide ion (mobile oxygen ion species) in the fuel cell are enhanced by recirculating an oxidizing gas-saturated electrolyte. Recirculating oxygen-saturated electrolyte through a liquid channel enhances the maximal current observed in a fuel cell. The use of a oxygen saturated electrolyte ensures that the reaction kinetics of the oxygen reduction reaction are fast and the use of convection ameliorates concentration gradients and the diffusion-limited maximum current density. The superoxide ion is generated in situ by the reduction of the oxygen dissolved in the gaseous electrolyte. Also, a dual porosity membrane allows the uniform flow of fuel (e.g., methane) on the fuel side, without allowing phase mixing. The capillary pressure for liquid intrusion into the gas phase and vice versa is quite large, estimated to be 1-10 psi. This makes it easier to control the fluctuations in gas/liquid velocity which might otherwise lead to phase mixing and the loss of fuel cell performance. In one variation, a dual-porosity membrane structure is incorporated in the system to allow uniform flow of fuel and prevent mixing of fuel with a liquid electrolyte. |

Data storage apparatus, and related systems and methods
The reliability of a low-power SRAM device fabricated in a small process node can be improved by using an SRAM cell with circuitry that reduces or eliminates contention between pull-up and pull-down devices during write operations. In the first stage of a write operation, the node N that stores the SRAM cell's bit value may be decoupled from a power-supply rail (“Rail 1”) by deactivating one type of “pulling” device (e.g., the type of pulling device that can pull the voltage of node N toward the voltage of Rail 1). Using pulling device(s) of the opposite type, the voltage of node N may then be pulled toward the voltage of the other power-supply rail (“Rail 2”). In this manner, the new SRAM cell may reduce or eliminate contention between pull-up and pull-down devices at node N during the first stage of the write operation. |

Memory subsystem I/O performance based on in-system empirical testing
A memory subsystem empirically tests performance parameters of I/O with a memory device. Based on the empirical testing, the memory subsystem can set the performance parameters specific to the system in which the memory subsystem is included. A test system performs the testing. For each of multiple different settings for multiple different I/O circuit parameters, the test system sets a value for each I/O circuit parameter, generates test traffic to stress test the memory device with the parameter value(s), and measures an operating margin for the I/O performance characteristic. The test system further executes a search function to determine values for each I/O circuit parameter at which the operating margin meets a minimum threshold and performance of at least one of the I/O circuit parameters is increased. The memory subsystem sets runtime values for the I/O circuit parameters based on the search function. |

The method includes steps of: a learning device (a) instructing a pooling layer to generate a pooled feature map corresponding to a 2D bounding box, and instructing a type-classifying layer to determine whether objects in the pooled feature map are truncated or non-truncated; (b) instructing FC layers to generate box pattern information corresponding to the pseudo-3D bounding box; (c) instructing classification layers to generate orientation class information on the objects, and regression layers to generate regression information on coordinates of the pseudo-3D bounding box; and (d) backpropagating class losses and regression losses generated from FC loss layers. Through the method, rendering of truncated objects can be performed while virtual driving, and this is useful for mobile devices and also for military purpose. |

Method, apparatus, and computer program product for determining vehicle lanes of a road segment based on received probe data
A method is provided to determine a number of vehicle travel lanes along a road segment. A method may include: receiving probe data from a plurality of probes, where the probe data includes probe data points having location and heading; matching the probe data to a road segment to generate map-matched probe data; analyzing the probe data relative to the road segment to establish a multi-modal distribution of probe data representing a distance of the probe data from a predefined reference position of the road segment; determining a number of vehicle travel lanes of the road segment based on peaks in the established multi-modal distribution being associated with individual lanes; and providing the determined number of vehicle travel lanes and the associated road segment to a map services database for lane-level route guidance. |
