Audio driver and method for transforming an electrical signal into air movement
An electromagnetic transducer for sound and ultrasound reproduction includes a substantially flat coil coupled to a diaphragm that is near to and facing the North or South side of a magnet. A very thin membrane made from a non-magnetic but electrically conductive material is independently mounted from the diaphragm and faces it.

Method for filter control and a filtering control device
Current deblocking filters are using the same filters with the same filtering strength irrespective of the block size and the size of the transform used. However, in the new video coding standards such as emerging HEVC the PU sizes can vary from 4 to 64 and the TU sizes can vary from 4 to 32. Therefore, filtering the same amount of pixels (e.g. two or three) from the block boundary for the block of size 4 can be excessive, while for the block size 32 it may not be enough, with the result that the boundary between two blocks is still visible. Hence, there is a need for an efficient deblocking filter control that can be used to reduce blocking artifacts at block boundaries and that does not have the above mentioned drawbacks. It is a general objective to provide an efficient deblocking filter control. Thus, the objective is solved by applying different filters for different block sizes such as CU, PU or/and TU sizes. Accordingly, the deblocking filtering strength is adjusted based on the block size, which implies that the amount of modification applied to pixels by the deblocking filter is varied depending on the block size. The amount of modification that is being varied is in one embodiment the number of pixels to be modified. |

Encoding techniques for banding reduction
Video encoders often produce banding artifacts on areas with smooth gradients and low levels of detail/noise. In this disclosure, a video encoding system identifies the banded areas and adjusts coding parameters accordingly. The video coder may include a pre-coding banding detector and a post-coding banding detector. The pre-coding detector may identify regions in the input picture with smooth gradients that are likely to have banding artifacts after encoding. The post-coding detector may identify regions in the reconstructed picture with visible banding. Usage of pre-coding detector and/or post-coding detector depends on how an encoder operates. In a single-pass encoding or during the first pass of a multi-pass encoding, the pre-coding detection maps are used. During picture re-encoding or during later passes of a multi-pass encoding, the post-coding detector maps are used. |

Circuitry and method for measuring negative bias temperature instability (NBTI) and hot carrier injection (HCI) aging effects using edge sensitive sampling
Toggling functional critical path timing sensors measure delays in toggling functional critical paths that continuously receive patterns from an aging pattern generator. Wear is accelerated. A margin delay adjustment controller sweeps margin delays until failures occur to measure delays. The margin delay is then adjusted in functional critical path timing sensors that add the margin delay to functional critical paths that carry user data or chip controls during normal operation. When the path delays fail to meet requirements, the functional critical path timing sensors signal a controller to increase VDD. When no failures occur over a period of time, the controller decreases VDD. Wear on the toggling functional critical paths is accelerated using both toggle and low-transition-density patterns. Circuit aging is compensated for by increasing margin delays to timing sensors. |

When a toggling functional critical path's delay fails to meet set-up timing requirement to a next register, the toggling functional critical path timing sensors signal a controller to increase VDD. When no failures occur over a period of time, the controller decreases VDD. A margin delay buffer adds a delay to the toggling functional critical path before being clocked into an early capture flip-flop. A reference register receives the test pattern without the delay of the toggling functional critical path, and an exclusive-OR (XOR) gate compares outputs of reference and early capture flip-flops to generate timing failure signals to the controller. |

Silicon-selective removal
A method of etching exposed silicon on patterned heterogeneous structures is described and includes a gas phase etch using plasma effluents formed in a remote plasma. The remote plasma excites a fluorine-containing precursor. Plasma effluents within the remote plasma are flowed into a substrate processing region where the plasma effluents combine with a hydrogen-containing precursor. The combination reacts with the patterned heterogeneous structures to remove an exposed silicon portion faster than a second exposed portion. The silicon selectivity results from the presence of an ion suppressor positioned between the remote plasma and the substrate processing region. The methods may be used to selectively remove silicon faster than silicon oxide, silicon nitride and a variety of metal-containing materials. The methods may be used to remove small etch amounts in a controlled manner and may result in an extremely smooth silicon surface. |

Method for improving quality of spalled material layers
Methods for removing a material layer from a base substrate utilizing spalling in which mode III stress, i.e., the stress that is perpendicular to the fracture front created in the base substrate, during spalling is reduced.
