Abstract: Water vapor is introduced into an inlet air stream (16) of an engine (12), for example, by a pervaporation process through a non-porous hydrophilic membrane (18). A water reservoir (20), which can contain contaminated water, provides a vapor pressure gradient across the hydrophilic membrane (18) into the inlet air stream (16), while the rate of delivery of the water vapor to a cylinder (38-40) is self-regulated by the rate of flow of air across the membrane. The hydrophilic membrane (18) therefore also filters the water from the water reservoir (20) to an extent that pure water vapor is provided to the air inlet stream (16). Delivery of water vapor can nevertheless be controlled using a hood (26) that slides over the hydrophilic membrane to limit its exposed surface area.

Abstract: A method of controlling in-rush current to a DC motor is disclosed. The method may include operating the DC motor in a first mode including applying back-EMF across a relay coil to maintain the relay in an open configuration when the back-EMF is below a predetermined voltage. The method may also include operating the DC motor in a second mode including applying the back-EMF across the relay coil to maintain the relay in a closed configuration when the back-EMF is equal to or above the predetermined voltage.

Abstract: Provided are techniques for space recovery with storage management coupled with a deduplicating storage system. A notification is received that one or more data objects have been logically deleted by deleting metadata about the one or more data objects, wherein the notification provides storage locations within one or more logical storage volumes corresponding to the deleted one or more data objects, wherein each of the one or more data objects are divided into one or more extents. In response to determining that a sparse file represents the one or more logical storage volumes, physical space is deallocated by nulling out space in the sparse file corresponding to each of the one or more extents.

Abstract: A paintball gun comprises: a body defining a gas storage chamber for connection to a source of pressurized gas, a breech into which paintballs can be loaded, and a hammer chamber; a bolt slidable in the breech and having a bolt inlet port; a hammer slidable in the hammer chamber and connected to the bolt; and a poppet valve comprising a valve body defining a valve inlet connected to the storage chamber, a valve outlet connected to the breech, and a blow back port connecting the inlet to the hammer chamber, and a valve member slidable in the valve body and movable between an open position, in which it allows gas to flow from the storage chamber through the valve inlet to the valve outlet, and a closed position in which it closes the valve, and a pair of magnets arranged to bias the poppet towards the closed position.

Abstract: Methods and apparatus are provided for block and rate independent decoding of LDPC codes. The disclosed LDPC decoders support multiple code block lengths and code rates, as well as a variable parity check matrix. The disclosed LDPC decoders decode LDPC codes that are based on a parity check matrix having a plurality of sub-matrices, wherein each row and column of the plurality of sub-matrices has a single entry. Each of the sub-matrices has at least one associated Phi-node, wherein each Phi-node comprises a memory device having a plurality of memory elements, wherein one or more of the memory elements may be selectively disabled. The Phi-nodes may be selectively disabled, for example, at run-time. The Phi-node optionally further comprises a multiplexer in order to provide a variable parity check matrix.

Abstract: Napthyridine derivatives useful in the treatment of bacterial infections in mammals, particularly humans, are disclosed.

Abstract: Memory modules are designed with multiple write buffers utilized to temporarily hold write data. “Write-to-buffer” operations moves write data from the memory controller to the write buffers while the memory module is busy processing read operations. Then, address-only “write” commands are later issued to write the buffered write data to the memory device. The write commands targeting idle DIMMs are issued in sequence ahead of writes targeting busy DIMMs (or soon to be busy). Moving the data via a background write-to-buffer operation increases the efficiency of the common write data channel and allows the write data bus to reach maximum bandwidth during periods of heavy read activity. The actual write operations, deferred to periods of when the negative affects of the write can be completely/mostly hidden. In periods of light read activity or when there are no reads pending, buffering data in the memory module enables the buffered data to be written in parallel across multiple memory modules simultaneously.
