The invention relates to a system and a method for detecting a surface shape of a human or animal body surface. A plurality of magnetic field sensors (2) arranged relative to one another in a sensor field (1) is placed on a plurality of surface regions of the body surface. A magnetic field generator (7) generates a magnetic field in the vicinity of the sensor field, so that a plurality of surface signals belonging to the surface regions are generated by using the magnetic field sensors (2). The surface signals serve as position signals with regard to the orientation and position of the magnetic field sensors in the magnetic field, so that the surface shape of the body surface is determined from the plurality of position signals of the magnetic field sensors (2) by using a signal processing unit (5).

Inventions herein include at least mostly optically clear orthodontic braces and feet orthotics (collectively referred to as “appliances”) with backscatter based sensors. These two categories of appliances share a common property requiring that the given appliance must be correctly custom manufactured to fit a patient's own particular geometry and dimensions of their teeth and/or feet in order to perform as intended. Incorporating such appliances with backscatter based sensors enables simple, easy, fast, efficient, and cost effective measurements, in real-time or near real-time, of stresses, forces, structural changes, and/or the like in the given appliance; which in turn can aid in determining if adjustments or re-manufacture of the appliance may be needed or desired; and/or wherein such measurements may aid in evaluating performance of the given appliance. In some embodiments, such measurements may also be taken remotely away from a practitioner; and then communicated to a remotely located practitioner.

Methods and apparatus for detecting body vital signs through the use of a Bioelectric Impedance Spectroscopy (BIS), either by (a) direct contact with the person (such as through one or more of their fingers) or (b) measurement of reflections from a field projected into the person's body. The techniques may be implemented using the projected capacitive touch array in a device such as the screen of a smartphone or tablet computer, or the touchpad of a laptop computer.

Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

A measurement apparatus includes a light source, a sensor including light detection cells including a first light detection cell and a second light detection cell, and an electronic circuit. The circuit causes the light source to emit a light pulse, causes the first light detection cell to detect a reflected light pulse from a target in an exposure period including at least part of a period from when an intensity of the reflected light pulse starts increasing to when it starts falling and generate a first signal, causes the second light detection cell to detect the reflected light pulse in an exposure period including at least part of a trailing period from when the intensity of the reflected light pulse starts falling to when it stops falling and generate a second signal. The circuit generates, based on the first and second signals, data representing states of the target.
