Techniques for delegating data processing to a cooperative memory controller
Processing functions are offloaded to a memory controller for nonvolatile memory by a host in connection with write data. The nonvolatile memory executes these functions, producing processed data that must be written into memory; for example, the offloaded functions can include erasure coding, with the nonvolatile memory controller generating redundancy information that must be written into memory. The memory controller holds this information in internal RAM and then later writes this information into nonvolatile memory according to dynamically determined write time and/or destinations selected by the host, so as to not collide with host data access requests. In one embodiment, the memory is NAND flash memory and the memory controller is a cooperative memory controller that permits the host to schedule concurrent operations in respective, configurable virtual block devices which have been configured by the host out of a pool of structural flash memory structures managed by the memory controller. |

Method and apparatus for resonator signal production and measurement
Techniques provide for passive Q switching in a bimodal resonator environment, where magnetic resonators are coupled for power transfer. A passive Q switch is responsive to a driving power from one magnetic resonator coupled to another magnetic resonator. After the driving power reaches a threshold, the passive Q switch shunts the receiving magnetic resonator, at least partially, to reduce the Q of that second resonator, which allows faster detection operation of the second resonator in some applications. The technique allows for fast Q switching in a bimodal resonator system, especially one having resonators having magnetic fields that are orthogonal to one another. |

Acoustic panel wall mounting
An acoustic panel wall mounting system including a rigid fastening plate and a panel anchor. The rigid fastening plate carries a field of first touch fastening features and defines an aperture for receiving a mechanical fastener to secure the fastening plate against a wall with the field of first touch fastening features exposed. The panel anchor has a helix extending from a rigid surface flange that carries a field of second touch fastening features on a surface opposite the helix. The anchor defines a tool receptacle used for twisting the helix into a panel. The field of first touch fastening features is engageable with the field of second touch fastening features to form a connection when brought into engagement as the panel is placed against the wall to contact the fastening plate with the panel anchor. |

Siding attachment system
A siding assembly includes a siding panel and an insulating panel securable to a wall using a siding attachment member. The siding attachment member includes openings extending therethrough in equally spaced relationship that align with slots formed in the foam panel. The spacing between centers of the foam panel slots corresponds to the spacing between centers of the openings in the attachment member. The slots in the foam panels are sufficiently wide to allow the foam panel to slide relative to the fasteners securing the foam panel to a wall. The siding attachment member may comprise a bracket with legs projecting rearward from a web and a siding support shoulder formed at a lower end of the web. Lines of weakness in the web and aligned notches in the shoulder facilitate cutting the bracket to a desired length. Reinforcement ribs are formed in the bracket web. |
