International Classification:

G01M019/00

US Classification:

702123, 702122, 702115, 714 30, 714 43

Abstract:

An apparatus, system and method for testing a peripheral device such that the device can remain installed in a housing and connected to a communication bus such as a SCSI bus. The apparatus, system, and method include a communication port that is connectable to a peripheral device connected to a terminated communication bus. The communication port is connected to a first transceiver and a second transceiver. A microcontroller is also connected to the first transceiver and the second transceiver. The microcontroller is programmed to detect an operation mode for the peripheral device and selectively activate the first transceiver or the second transceiver based on the detected operation mode. The microcontroller is further programmed to perform a logical diagnostic test on the peripheral device using the activated transceiver. A user interface is included to communicate to a user a result of the diagnostic test.

International Classification:

H02P 304

US Classification:

318366

Abstract:

An automated tape library employing a motorized robotic picker wherein the electric motor driving the robotic picker is equipped with two brakes that act simultaneously. The first is a mechanical brake which uses a spring to push a fixed brake pad against the rotating motor. During normal motor operation, an electric solenoid is used to overcome the spring and disengage the brake pad from the motor. When the robotic picker is to be mechanically stopped, the solenoid voltage is turned off and the solenoid releases the spring placing the brake pad in contact with the motor. The second brake is a dynamic electrical brake which makes use of the back emf of the motor to drive a current back into its own windings such that the motor decelerates. The circuit further prevents mechanical brake engagement even at lower motor speeds when back emf is relatively low but robot speed is fast enough to cause mechanical damage if stopped via the mechanical brake.
