Method and apparatus for indirect asset tracking in materials handling environments with Radio Frequency Identification (RFID). In one embodiment, receptacles in a materials handling facility may be equipped with RFID tags. Agents within the materials handling facility may be equipped with RFID readers, which may be integrated in or attached to gloves, wristbands, or other devices. The location of each receptacle to which an RFID tag is attached may be associated with the unique identifier of the RFID tag. When an agent's hand approaches or enters a receptacle equipped with an RFID tag, the RFID reader may detect the presence of the RFID tag. This information, in combination with known information such as the location of the receptacles, may be used, for example, for information gathering and/or for quality checking in picking, stowing, rebinning, and/or other materials handling processes.

A mechanism is provided in a debugger for building a file information database while significantly reducing debug startup time. For each line number table, the mechanism of the present invention reads the header section and determines all the source files that contribute to the line number table. The mechanism also makes note of the line number table offset. The mechanism then inserts the source filename into the file information database. In one preferred embodiment, the file information database is implemented as a hash table. Searching time occurs during an interactive debug session; therefore, the searching time is not easily detectable to a user, thus creating the perception of a faster interactive debugging session.

A method, medium, and apparatus of a self-propelled mobile unit with obstacle avoidance during wall-following. In the self-propelled mobile unit, a carrying unit may move the mobile unit by using a transmitted power, and a sensor unit can detect an obstacle and a wall, which may be respectively placed in front of and to the side of the mobile unit, with respect to a moving direction of the carrying unit. A controller may direct the carrying unit by generating a path along which the carrying unit moves according to a detection result from the sensor unit. Accordingly, the controller can direct the carrying unit to move while maintaining a predetermined distance (within a predetermined range) from the wall. If the sensor unit detects an obstacle, the controller directs the carrying unit to move in an obstacle free direction.
