Abstract: A electric power steering control device equipped with a motor having a resolver detection unit includes: an ambient temperature detector for detecting ambient temperature around a portion generating heat by current flow; a motor temperature detector for, based on a signal from the resolver detection unit of the motor, estimating the temperature of the portion generating heat; and an abnormality determiner for comparing the temperature detected by the ambient temperature detector with the temperature detected by the motor temperature detector and determining that the ambient temperature detector is abnormal.

Abstract: The present invention concerns a control system for an electric motor, wherein an operating mode with predetermined value assignments is selected for a parameter set for controlling an electric motor and the pulse frequency of a control signal for the electric motor is set in accordance with the selected operating mode in order thereby to signal to the electric motor the selected value assignments for the parameter set.

Abstract: Techniques for automatic data warehouse generation are disclosed herein. A first data set is received. The first data set includes a plurality of tables and includes a plurality of keys. A dimensional model is mapped onto the first data set. A schema is automatically generated based on the dimensional model.

Abstract: An apparatus, system, and method are disclosed for dynamic tape stick and tape break detection. A first counter increments a first count and resets a second count in response to a sensor pulse from a first sensor of a first tape servo. A second counter increments the second count and resets the first count in response to a sensor pulse from a second sensor of a second tape servo. A detection module detects either the first count or the second count exceeding an error threshold.

Abstract: A stop command detecting unit detects an operation transition from fast forwarding/rewinding modes to a stop mode, a take-up side reel braking unit and a supply side reel braking unit start a braking operation based on the stop command, and a driving motor of the take-up side reel is driven at a specified current value set by a motor current value setting unit for a specified time set by a current adding time setting unit to provide the take-up side reel with rotary torque in the winding direction. Hence, the supply side reel rotates together with the take-up side reel until the supply side reel is stopped, thereby preventing occurrence of a slack on the tape.

Abstract: A method for preventing a reverse connection between a takeup leader connected to a single reel tape drive and a tape cartridge leader connected to a magnetic tape media contained in a single reel tape cartridge that is loadable into the tape drive. The method comprises detecting a missed connection between the takeup leader and the tape cartridge leader following a failed load operation. The load operation includes loading the tape cartridge into the tape drive, connecting the takeup leader and tape cartridge leader, and winding the tape media to the read position. In response to detecting the missed connection, a torque is applied to the takeup leader to retain it in a loaded position away from the tape cartridge leader while the tape cartridge is ejected from the tape drive. In response to ejecting the tape cartridge from the tape drive, the takeup leader is reset to the unloaded position for a subsequent loading operation.

Abstract: A magnetic recording and reproducing apparatus feeds magnetic tape from a supply reel to a take-up reel driven by a motor. Sensors generate signals responsive to each revolution of the supply reel and to the rotation of the motor. An end-of-tape detector counts the number of motor-sensor signals per revolution of the supply reel, and thereby detects the approaching end of the magnetic tape, so that the motor can be slowed before the end of the tape is reached. A detection threshold may be selected or computed in advance by using information provided by a third sensor, which generates a signal responsive to each revolution of the take-up reel.

Abstract: A sensing assembly for use in determining if magnetic tape within a single reel tape cartridge properly connects to a takeup reel within a tape drive during loading of the tape cartridge, so that the magnetic tape can be wound between the tape cartridge and the tape drive as data is transferred to or from the magnetic tape. The sensing assembly comprises at least one sensing apparatus for providing feedback on connection status to prevent connection failures from rendering the tape drive inoperable.
