Title: An improved compression algorithm for video compression codecs
Inventor: MRAK MARTA
IPC: H04N19/132
Filed: 2013-11-04
Abstract: Encoding video data comprises generating or receiving a prediction block containing coefficients representative of an original picture block. A residual is calculated by subtracting the original picture block and the prediction block from each other. The prediction block is generated or modified by generating coefficients at a first set of locations (first region) which are preserved or generated according to usual intra or inter prediction coding while generating coefficients at a second set of locations (second region) according to substitution with other values. The prediction coefficients in locations with very low correlation with the original can therefore be discarded and replaced with more informative content. The selection of locations / regions may be performed using a mask, the optimal mask being selected from a plurality of shapes. The modified coefficients improve the efficiency of the compression process once the prediction block is subtracted from the original block to generate a residual signal for quantisation and encoding. The processes may operate in either of the frequency or the spatial domain. The prediction block may also be modified according to its size and/or shape.

Title: Implementing spin torque oscillator erasure prevention in microwave-assisted magnetic recording (MAMR) hard disk drives
Inventor: JUN AOYAMA
IPC: G11B5/31
Filed: 2016-06-02
Abstract: Erasure resulting from remnant magnetization in a spin-torque oscillator 206 (STO) is prevented for microwave assisted magnetic recording (MAMR) hard disk drives (HDDs). A first voltage is applied to an STO element in the MAMR head at the time of write operation. A second voltage is applied to the STO element at the time of read operation, or not write operation, to prevent STO erasure otherwise resulting from stray field of remnant magnetization of the STO at the time of read operation. The voltage applied to the STO and current 314 during reading may have a lower amplitude and different polarity than during writing. The direction of magnetization in a field generation layer 304 of the STO element may be changed during a read operation.

In another embodiment an apparatus for providing an indication of the state of charge of a battery comprises a battery management system (BMS) and a charge determiner and is configured such that when the battery management system switches to a power saving sleep state power to the charge determiner is maintained.
