The present invention provides an apparatus and method for determining the dimension of an object. The apparatus of the present invention includes a transmitter that is positioned at a first point of interest on an object. The transmitter transmits a scanning light beam rotated at a predetermined angular velocity. Located at a second point of interest on the object is a target. At least a portion of the target defines a first plane that reflects the scanning light beam as the scanning light beam traverses across the target. To receive the reflected signal from the target, the apparatus of the present invention further includes a receiver positioned at the first point of interest. Additionally, the apparatus of the present invention includes a processor for processing the reflected signal and determining the dimensions of the object. In operation, the scanning light beam scans the target, where the radius of the arc that the light beam traverses across the target defines the dimension of the object. To determine the radius of the arc, the apparatus of the present invention uses the known width of the target, the angular velocity of the scanning light beam, and the time required for the scanning light beam to traverse the target. In addition to determining a dimension of an object, the present invention also provides apparatus and method for calibrating the measurement system and determining when the system is in steady state operation.

Portable measurement apparatus for determinging the dimensions of an object and associated method

A RF data communications system for remotely collecting data and a method of developing applications for such a system are provided. The RF data communications system preferably has a first computer including at least a first microprocessor, a first screen display, and a first data screen file positioned representing a first predetermined screen display format. A first RF data transceiver is positioned in electrical communication with the first microprocessor of the first computer for transmitting and receiving RF data, and a second RF data transceiver is positioned remote from the first RF data transceiver and the first computer for transmitting RF data to and receiving RF data from the first RF data transceiver. A second computer is positioned in electrical communication with the second RF data transceiver and remote from the first computer. The second computer preferably is arranged for collecting data remote from the first computer and includes at least a data sensor, a second microprocessor, a second screen display, and a second data screen file representing a second predetermined screen display format. The second screen data file substantially corresponds to the first data screen file so that the second screen display format substantially corresponds to the first screen display format and so that modifications to the first data screen file are responsively made to the second data screen file and responsively displayed on the second screen display to a user thereof.
