Title: Sound data decoding apparatus
Inventor: OZAWA KAZUNORI
IPC: G10L19/005
Filed: 2007-07-23
Abstract: An audio data decoding device using the waveform encoding method includes: a loss detector, an audio data decoder, an audio data analyzer, a parameter correction unit, and an audio synthesis unit. The loss detector detects whether audio data has a loss. The audio data decoder decodes the audio data and generates a first decoded audio signal. The audio data analyzer extracts a first parameter from the first decoded audio signal. The parameter correction unit corrects the first parameter according to the result of the loss detection. The audio synthesis generates a first synthesis audio signal by using the corrected first parameter. Thus, it is possible to prevent deterioration of the sound quality in audio data error compensation.

Title: Error correction for disk storage media
Inventor: PASHENKOV SERGE
IPC: H03M13/00
Filed: 2007-08-09
Abstract: Embodiments of the invention provide methods and systems for improving the reliability of data stored on disk media. Logical redundancy (101) is introduced into the data, and the data within a logical storage unit is divided into sectors that are spatially separated (151) by interleaving them with sectors of other logical storage units. The logical redundancy and spatial separation reduce or minimize the effects of localized damage to the storage disk, such as the damage caused by a scratch or fingerprint. Thus, the data is stored on the disk in a layout that improves the likelihood that the data can be recovered despite the presence of an error that prevents one sector from being read correctly.

Abstract: Electrical energy is conveyed via an implanted tissue stimulation system into tissue of the patient over a period of time. Electrical parameter data (e.g., impedance data and/or field potential data) is measured based on the electrical energy conveyed into the tissue of the patient, whereby the electrical parameter data is modulated in response to the physical activity of the patient to generate a time-varying signal (e.g., an oscillating signal). The time-varying signal is analyzed, and the physical activity of the patient (e.g., the physical activity level of the patient or the physical events performed by the patient) is tracking during the time period based on the analyzed time-varying signal.
