Method and apparatus for assessment of bone age using ultrasound
First Claim
1. A method of assessing the bone age of an individual for controlling access of the individual to a service, a device, or a location, comprising:
- sensing a degree of ossification of an examined bone of the individual by using a through-transmission ultrasound technique to transmit an ultrasound wave transversely through said examined bone and measuring a parameter of the sound velocity of said ultrasound wave, wherein said degree of ossification of the bone of the individual is determined by sensing the presence, absence, or thickness of a bone growth-plate in the examined bone.

Abstract
A method and apparatus for controlling access of individuals to a service, device or location in order to restrict access to members of a particular age and/or gender category, by machine-sensing a predetermined biometric characteristic of the individual indicative of the particular age and/or gender category, and utilizing the machine-sensed characteristic for automatically controlling access of the individual. The method and apparatus are particularly suited to controlling access of children to certain Internet sites, TV programs, chat rooms, or other places inappropriate to children.

5. A through-transmission ultrasound apparatus for examining a bone of an individual, for assessing the bone age of the examined bone, and for controlling access of the individual to a service, a device, or a location, said apparatus comprising:
-
an ultrasound transmitter configured to transmit an ultrasound wave transversely through said bone; an ultrasound receiver configured to receive said ultrasound wave after transmission through said bone, and to produce an output signal corresponding to the degree of ossification of said bone, wherein said output signal indicates the presence, absence, or thickness of a bone-growth plate in the examined bone; and an access control logic, wherein the access control logic produces an access control logic output signal for controlling the access of the individual to the service, the device, or the location. - View Dependent Claims (6, 7, 8, 11, 12)
