Definitions

  • An accurate baby scale is required when proper baby feeding and baby growth are to be monitored. Determining the quantity of milk breastfed to the baby usually requires weighing the baby before and after a natural breastfeeding, with precision of about 5 grams. This requirement is traditionally met by expensive scales that include a weighing surface supported on four load sensors. Each such sensor requires separate calibration. The traditional baby scales also require a large space, which is not always available.

  • a method for weighing a baby including restraining the baby in a baby car seat, hanging a handle of the car seat from a rigid holder extending from a load sensor, the load sensor mounted with 3 degrees of freedom from a handle during weighing, lifting the handle and the baby car seat off of the ground to obtain a consistent, selected weight measurement, and storing the measurement data in a non-volatile memory together with an indication of which measurement was taken.

  • One feature of the device 10, of being compact and safe, is met by weighing the baby while the baby is lying or sitting in a safety seat (not shown), such as a car seat for newborn babies or infants, which includes a handle 20. In this way, the baby is restrained during weighing and cannot roll off the scale.
  • the device functions as a hanging scale and is designed to be attached to the handle 20 of a baby seat and to be lifted by an operator by means of the device handle 12. The weight of the baby can be measured when the baby seat is above the ground, by the force between the device handle 12 and the load (i.e., the baby seat) attached to the other side of a load sensor 14.

  • the handle 20 (shown in cross-section) is held in place on holder 16 by means of a flexible or elastic band 18 or belt, which holds the handle in place from above and prevents the handle from sliding out of the holder 16.

  • the elastic band 18 permits the handle 20 of the baby seat to pivot within holder 16 until the baby seat is hanging substantially vertically from the device.
  • the coupling between the upper part of the load sensor and the handle of the device is designed to have freedom in all directions during weighing, as by use of a ball joint or other pivot mechanism providing at least three degrees of freedom.
  • the load can turn about the vertical axis of the pivot mechanism, it can swing forwards and backwards, and side to side, in order to reach a vertical orientation for optimal weighing.
  • the orientation of the handle held by the operator is decoupled from the load sensor, so the load is free to hang vertically, regardless of the angle of the handle, and the weight measurement is not affected by misalignments and torsion forces coming from the hand of the operator.
  • the device is calibrated after complete assembly in the factory, using a selected calibration weight and data communication with the device.
  • a selected calibration weight and data communication with the device is eliminated.
  • Zeroing is performed just before each measurement, when the device is coupled to the baby seat but is not lifted, so there is no weight acting on the load sensor. This permits adjustment of the weighing device to compensate for or substantially eliminate sensitivity errors due to internal stresses or temperature changes, etc. This zeroing is performed by using a cradle 17 (described in more detail below) that supports the weight of the handle of the device and decouples it from the load sensor. Thus, the zero level is not affected by the initial orientation of the handle or by torsion moments .
