Abstract: A system securely buffers hard disk drive data using a host side eXlusive OR (XOR) encryption engine. A host communicates with an encryption interface interposed between the host and a client. Communicatively coupled to the encryption interface is an external buffer for the collection and processing of data. A host side XOR encryption engine, using a random seed, encrypts data originating from the host and places it on the external buffer. Once collected at the buffer and ready for transmittal to the client, the encrypted data is retrieved by the encryption interface and decrypted using the same random seed. The clear data is then encrypted once again using a robust encryption means such as Advance Encryption Standard (AES) encryption by a client side device for conveyance to the client.

Abstract: A system and method for precisely positioning a robotic tool relative to a worksite, wherein the worksite includes a positioning target located at a fixed position relative thereto is disclosed. A camera coupled to the robotic tool detects the target and generates a position signal representing a current position of the robotic tool relative to the worksite. A system controller receives the position signal and computes a parallax-corrected position based on the distance to the worksite. In addition, the system controller produces a correction signal representing the difference between the parallax-corrected position and the current position. A mechanical arm precisely positions the robotic tool and the worksite relative to each other.
