Abstract: A method includes transmitting, from a storage system to a user system, information that, when processed by the user system, causes the user system to display a current view representing the one or more items. The method also includes selecting, at the storage system in response to a first user input signal that identifies at least one item from one or more items that are stored at the storage system, a removal operation based on one or more predetermined criteria, wherein the one or more predetermined criteria include a view type of the current view. The method also includes performing, at the storage system, the removal operation with respect to the at least one item.

Abstract: The elevator performance meter is an embedded processor device specifically designed to measure the variations in velocity, acceleration, jerk and run duration as an elevator ascends and descends along a vertical axis. The performance meter utilizes an internal processor that is directly connected to a sensor via an analog to digital conversion unit, a program storage device, a display, a keypad, and power subsystems that are all contained within a single enclosure. The performance meter includes a display screen on its top surface with a keyboard for entering in operator menu selections. The performance meter is placed on the floor of an elevator and the embedded sensor measures certain physical properties of the elevator as it makes a floor-to-floor run. The measurement data is presented on the internal display as an alphanumeric readout that allows an elevator's performance to be easily defined.
