Abstract
A weight measurement module operatively coupled to a piece of luggage for determining the weight of the luggage and its contents. The weight measurement module includes one or more load cells, a processor operatively coupled to the one or more load cells, and a display operable to display the weight of the luggage and its contents.
Claims16
A bag comprising:
- a plurality of side walls, a top wall connected to each of the side walls, a bottom wall connected to each of the side walls, the plurality of side walls, the top wall, and the bottom wall defining an enclosure;
- a handle coupled to the top wall;
- and
- a weight measurement module coupled to the handle through the top wall, the weight measurement module including
- a housing coupled to an interior surface of the top wall,
- a power source supported by the housing,
- a processor supported by the housing,
- a first load cell and a second load cell each electrically connected to the processor and mechanically coupled to the handle and the housing with a fastener, and
- a display coupled to the housing and an exterior surface of the top wall, the processor operable to process data received from the first load cell and the second load cell and transmit data to the display indicative of weight of the bag, and
- wherein the first load cell and the second load cell include a common beam, and wherein the beam substantially extends the length of the housing.

A bag comprising:
- a plurality of side walls, a top wall connected to each of the side walls, a bottom wall connected to each of the side walls, the plurality of side walls, the top wall, and the bottom wall defining an enclosure;
- a plurality of wheels coupled to the bottom wall;
- a retractable handle coupled to one of the side walls, the top wall, and the bottom wall;
- a handle coupled to the top wall, the handle including a first end and a second end;
- and
- a weight measurement module coupled to an inside surface of the top wall, the weight measurement module including
- a housing having a first end and a second end, the first end of the housing coupled to the first end of the handle, the second end of the housing coupled to the second end of the handle,
- a beam having a first end and a second end, the first end of the beam coupled to the first end of the handle and the first end of the housing, the second end of the beam coupled to the second end of the handle and the second end of the housing, a first strain gage connected to the beam near the first end of the beam defining a first load cell, and a second strain gage connected to the beam near the second end of the beam defining a second load cell,
- a processor electrically connected to the first load cell and the second load cell, the processor operable to receive data from the first load cell and the second load cell and generate a digital signal representative of the weight of the bag and items positioned in the enclosure based on the data received from the first load cell and the second load cell,
- a display electrically connected to the processor, the display operable to present a numerical value based on the digital signal, and
- a switch electrically connected to the processor, the switch operable to activate the processor to generate the digital signal when the bag is elevated from the ground.
