The amount of acceptable flux is maintained within limits modified by information about the region of the body being scanned so that different precisions may be maintained for different body regions. Scan speed and current may be controlled so that scan speed is maximized within the current limits. Essentially continuous flux control can be achieved.

A method for the in vivo non-invasive characterization of the material and architectural properties of a bone in which an ultrasonic wave is introduced into a bone in such way as to produce one or more guided wave modes within the bone, and the signals emerging from the bone are stored and analyzed to determine the propagation characteristics of the guided wave/s. These measured guided wave propagation characteristics are then processed to obtain estimates of desired bone properties such as cortical thickness, bone density and bone elastic constants.

A personal identification apparatus is disclosed by which personal identification can be performed making use of an impulse response obtained from a pulse signal transmitted by a living organism. A pulse generation section generates a pulse, and a speaker applies the pulse amplified by an amplifier to a finger of a user touching with the speaker and a microphone. The pulse signal is transmitted to the microphone with an attenuation characteristic that depends upon, for example, a transmission distance that depends upon the length and the thickness of the finger and characteristics of the living organism such as the thickness of the flesh and the bone density. A data synthesis processing section synthesizes the pulse and an impulse received by the microphone and amplified by an amplifier. A template recording section records a template to be used as a reference of discrimination in an authentication process together with a user ID and so forth. A comparison discrimination processing section refers to the template recording section to discriminate whether or not an impulse response inputted from a memory coincides with one of templates of registered users.

A sleeve that provides mechanical stimulation to the arm to prevent bone density loss. A primary goal of this product is to prevent bone density loss that occurs during extended space travel. For one embodiment, only the predefined frequency specifications had to be met (between 40 Hz and 60 Hz). By meeting these frequencies for a duration of 30 minutes the product will theoretically prevent the loss of bone density. Additionally, clinical trials will need to be conducted before this product can be marketed. The product includes of several mechanical vibrators attached to a sleeve. The vibrators are small unbalanced-mass motors which are similar to those found in cell phones. The motors are encased in dome shaped housings designed to reduce lateral vibrations along the arm. The product is controlled using an Arduino board attached to the sleeve that actuates the motors. The motors, in turn, provide the specified frequency to the arm for 30 minutes. The spacing of the motor housings was determined from PEA simulations. This resulted in the motors being spaced 2 in apart along the arm at 90° increments around the axis of the arm. The controller has a display that allows for user interaction and includes a session timer. In addition, this product is contemplated for use in reducing muscle atrophy, eliminating bed sores, and treating other ailments that can result from sedentary behavior.
