Abstract
Detecting an object using sound waves includes outputting a sound wave from a transducer, receiving an echo after outputting the sound wave, obtaining a threshold value based on the echo and plural other echoes that are within a predetermined range of the echo, and determining if the echo is a result of the sound wave based on the threshold value.

60. A method of controlling a mobile robot, the method comprising:
-
outputting multiple, sequential sound waves; receiving echoes of the outputted sound waves; obtaining a threshold value based on a latest one of the echoes and previously received ones of the echoes determined to fall within a predetermined range of the latest echo; determining if the latest echo is a result of a latest one of the outputted sound waves based on the threshold value; and controlling the mobile robot based on the determination of whether the latest echo is a result of the latest outputted sound wave. - View Dependent Claims (61, 62)

63. An apparatus for detecting an object using sound waves, the apparatus comprising:
-
a transmitter to output multiple, sequential sound waves; a receiver to receive echoes of the outputted sound waves; and a processor configured to obtain a threshold value based on a latest one of the echoes and previously received ones of the echoes determined to fall within a predetermined range of the latest echo, and determine if the latest echo is a result of a latest one of the outputted sound waves based on the threshold value. - View Dependent Claims (64, 65)

66. A method of controlling a mobile robot, the method comprising:
-
receiving plural reflections of corresponding emissions; determining a threshold value based on a target reflection and received reflections determined to each result from a corresponding emission; comparing the target reflection to the threshold value, the target reflection comprising one of the plural reflections; determining if the target reflection is a reflection of a latest emission based on the comparison to the threshold value; and controlling the mobile robot based on the determination of whether the target reflection is a reflection of the latest emission. - View Dependent Claims (67, 68, 69, 70, 71)

72. An apparatus comprising:
-
a receiver to receive plural reflections of corresponding emissions; and a processor configured to determine a threshold value based on a target reflection and received reflections determined to each result from a corresponding emission, and determine if the target reflection is a reflection of a latest emission based on the threshold value and the target reflection, the target reflection comprising one of the plural reflections. - View Dependent Claims (73, 74, 75, 76, 77)
