Definitions

  • This invention relates to a method for determination of the weight of human body and a device for performing it- It can be used also for the determination of loads carried by a person by differential measurement.
  • a large variety of body weight scales are available which, however, are stationary and not designed for permanent determination of the body weight during normal walking or sporting activities.
  • the invention as claimed solves the above described problems by providing a method for determination of the weight of human body which can be performed permanently according to the actual needs.
  • Suitable sensors can be chosen from a variety of compression and tension force sensors available on the market and discussed in detail in G ⁇ nter W.Schanz, "Sensoren, Fiihler der Messtechnik", Dr.Aired Hutig VErlag, Heidelberg, 1986, in particular on pages 270 - 325.
  • the preferred piezoresistive or piezoelectric pressure transducers convert pressure exerted by the foot of the human body into an electric signal.
  • the pressure transducer is connected either by wire or wire-less to a pressure measuring and indicating apparatus.
  • This apparatus may comprise a digital voltmeter which receives the force-proportional signal from the pressure transducer.
  • the pressure transducer (one or several) are embedded in a shoe insert which can easily be inserted in and removed from the shoe. Arranging several pressure transducers over the whole area of the foot contact allows for compensation of non-uniform application of force to the supporting means of the foot.
  • the pressure transducers are then distributed in a matrix array over a suitable force measuring carpet which may have the form of a shoe insert. The electric signals derived from such a matrix array will then be supplied to an evaluation apparatus which calculates the exerted total force, transforms it into body weight of the person exerting such a force and indicates the body weight on a suitable display, e.g. a wrist watch.
  • Fig. 1 is a schematic perspective view of a device for performing the method according to the invention
  • Fig. 2 shows a block diagram of a device for performing the method according to the invention.
  • Fig. 1 shows a device 1 for performing the method according to the invention, incorporated partly in a shoe 2 and partly in a wrist watch 3 on the optical display 9 of which the body weight data are permanently displayed.
  • the pressure exerted by a persons foot 12 on the sensing means 5 in the form of a pressure sensor incorporated in the supporting means 13 (i.e. the sole) of shoe 2 is used for continuously obtaining body weight data of the person of which the body weight shall be monitored.
  • the device 1 of Fig. 1 is explained more in detail with reference to Fig. 2; it consists of an electrical power supply battery 4 connected to a piezoresistive sensor 5 which in turn is connected to a transmitter 6 which generates infrared light for transmitting the data wireless to the wrist watch 3 which contains to this effect a receiver 7, a microprocessor 8 (with a RAM and a ROM) and an optical display 9.
  • the display 9 indicates the body weight data by means of a LCD or LED arrangement.
  • a LCD or LED arrangement In case that only one sensor 5 is used in the shoe 2 there is the need of statistical processing of the data measured, in order to obtain an average of the body weight of the person wearing the shoe 2. This can be effect by the Gauss equation called exp(x 2 ).
  • an active charge amplifier 10 which functions as a signal preamplifier may be used.
  • the preamplifier may be arranged in or on the sensor 5.
  • the wireless transmitter 6 can take the form of a high-frequency transmitter, the carrier signal of which is modulated by the measurement signal (input).
  • the wireless transmitter 6 can take the form of an infrared or laser transmitter device. A digital signal transmission is particularly advantageous.
  • the digital sensor data can also be transmitted via optical waveguide cables.
  • the analog measurements signals of the sensor 5 must be converted into digital signals by means of a converter 11.
  • Various methods are sufficiently known from the state of the art. For this purpose it is of advantage to provide for serial output of the digital values of the converter 11, since a parallel output necessitates additional expense as regards transmission devices.
  • the signal preamplifier 10 and the analog/digital converter 11 are combined into a single functional unit; e.g. by using a charge/frequency converter in which the charge amount of the mechanoelectrical converter is directly converted into a frequency-proportional signal.
  • an absolute pressure sensor is used, for instance the absolute pressure sensor KPY 14 manufactured by Siemens AG, Kunststoff (Germany) .
  • This absolute pressure sensor is embedded in an elastomeric material in such a manner that there is- no essential contact of the absolute pressure sensor (when inserted in the shoe) to either the foot or the shoe sole. This results in a uniform pressure distribution and good protection of the absolute pressure sensor 5, any compensation resistors, cables and of the transmitter 6 against environmental influences in particular against penetration of gases, humidity and sweat.
  • the senor 5 is configured as a transducer diaphragm. This leads to an extremely compact and light-weight sensor 5 being in no way an obstruction when inserted in the shoes 2 of a person. It is, therefore, possible with no problem whatsoever to carry out body weight measurements on the wearer under dynamic loading conditions.

Abstract

Selon ce procédé de détermination du poids du corps humain, la force ou la pression exercée par le pied (12) sur un support (13) du pied (12) est mesurée au moyen d'un détecteur (5) incorporé dans une chaussure (2) et générant un signal électrique proportionnel ou analogue à ladite force ou pression. Les signaux sont transmis vers un endroit éloigné où ils sont convertis sous forme de données relatives au poids corporel sur l'affichage (9) d'une montre-bracelet (3).
