Abstract: Systems and methods are described for automatic calibration of robotic mechanism functions according to accurate decoding and locating of target features using spot scanning. For example, a robotic mechanism in a storage library has one or more integrated scanners that can acquire contrast and/or topographic scan data from a scan window that represents a profile of the scan window expected to have one or more target feature sets. The scan data can be decoded according to predefined target masks (e.g., target type-specific fit tables) at a number of decode threshold levels to estimate target feature values, which can be used to converge on (or otherwise generate) a purported target definition with purported feature values. The purported target definition can be used to facilitate various functions, such as automatic calibration of robotic mechanism positioning and object identification.

Abstract: A system and method of adaptively engaging cartridges stored in an automated cartridge library are provided. Upon receiving a request to extend a reach mechanism of a robot arm to engage a cartridge stored in a selected cell, a library controller initiates a move profile to extend the reach mechanism from a starting position toward the cartridge. The move profile comprises a set of commanded positions and corresponding commanded velocities. A motor controller in communication with the library controller compares a sensed position of the reach mechanism, provided by a position feedback sensor associated with a reach motor, with the commanded position to determine a position error. The motor controller maintains the move profile until the position error exceeds an error threshold, indicating engagement of the cartridge by the reach mechanism.

Abstract: Headband lamp apparatus includes a band portion, a lamp portion, a power supplying portion and a recharging portion. The band portion includes an adjustable elongated flexible band member. The lamp portion includes a lamp socket disposed on a free end of an adjustable linkage. A protective housing surrounding a lamp bulb has an adjustable lens located adjacent a free end of the housing. The power supplying portion includes a plurality of batteries mounted on the band member along the length thereof and spaced from the lamp portion. Each pair of the batteries is retained on the band member with a clip member. Electrical conductors along the length of the band member electrically connect the lamp portion with the batteries. The recharging portion includes a socket member disposed along the length of the band member remote from the lamp portion and connected electrically with the conductors.
