Multi-path signal processing for microelectromechanical systems (MEMS) sensors is described. An exemplary MEMS sensor apparatus can comprise a single MEMS sensor element and an associated integrated circuit (IC) that facilitates generating multiple output signals having different output signal electrical characteristics required by a host system. Provided implementations can minimize cost and IC die area of associated MEMS sensor apparatuses and systems by employing one or more signal multiplexers (MUXs) on a single common signal path from the single MEMS sensor element. In addition, various methods of generating multiple output signals having different output signal electrical characteristics from a single MEMS sensor element are described.

Multi-path signal processing for microelectromechanical systems (MEMS) sensors

Systems and methods are disclosed for implementing optical image stabilization (OIS) in a mobile device. One or more functions associated with OIS may be performed by hardware and/or processing resources that are provided independently of a camera unit.

Systems and methods for optical image stabilization using a digital interface

Methods and apparatus for reading data from the burst cutting area of a digital video disc. The present location of an optical head assembly is determined. The distance from the present location of the optical head assembly to the burst cutting area is calculated. The optical head assembly is moved by the calculated distance toward the burst cutting area. Data stored in the burst cutting area is read. The read data is checked for error. Repeat until there is no error in the data.

Method and apparatus for seeking the burst cutting area of DVD media

A method and apparatus for transferring optical data from a DVD in response to a request from a host. When a data request is issued, a portion of the request containing the target ID for the target data block is used by a comparator circuit to locate the target data block. Another portion of the request containing the number of data blocks requested is used by a monitoring circuit to monitor data block transfer from a DVD to a data buffer once the target data block is located. The monitoring circuit stops data transfer when all of the requested data blocks have been transferred. Each data block is transferred into a data buffer containing areas separated by pointers. In a scratch area of the data buffer, the data block is error corrected, error checked and descrambled. After error checking and descrambling, the data portions of the data block are transferred to a data area in the data buffer, the auxiliary portions of the data block are transferred to an auxiliary area in the data buffer and the status of the error checking is latched into registers. Before any data is transferred from the data buffer to the host through an interface, the data status in the registers is checked. If no error is found in the data, then the corresponding data portions of the data block is transferred to the host.
