Abstract: Disclosed are methods and devices useful in the field of image processing and display Disclosed are also methods and devices useful in the field of ophthalmology and, in some particular embodiments, useful for the non-invasive treatment and/or prevention of refractive errors.

Abstract: Disclosed is a wearable optical devices for a human subject, comprising: a transparent lens; a wearable frame configured to maintain the lens in front of an eye of a human subject; a transparent pixelated active optical element where the pixels of the active optical element have an optical property with a changeable value; an eye tracker; and a controller configured to set a value for an optical property of the pixels of the active optical element so as to create an image mask through which at least some of the light reaching the feye passes through, thereby modifying the image formed on the retina of the first eye.

Abstract: A method includes receiving a plurality of raw PCG data inputs; applying at least one binary classification technique to each of the raw PCG data inputs to generate a respective plurality of filtered PCG data inputs; applying at least one divide-and-conquer algorithm to detect heartbeat compartments in each of the plurality of the filtered PCG data inputs based, at least on part, on assumptions that noise signals and S1-S2 alternation acoustic signals are non-stationary over a one-minute time interval; classifying each compartment of the heartbeat compartments in each of the plurality of the filtered PCG data input as a maternal compartment or a fetal compartment based at least on a plurality of referenced maternal QRS positions; combining a plurality of maternal compartments to identify at least one actual maternal heartbeat; combining a plurality of fetal compartments to identify at least one actual fetal heartbeat.

Abstract: A garment includes a securing portion operable to removably secure the garment about an abdomen of a wearer; a sensor attachment portion pivotably attached to the securing portion, the sensor attachment portion including a sensor mount configured to receive and retain a sensor therein; and a sensor received in the flexible sensor mount; the securing portion and the sensor attachment portion being configured such that, when the securing portion is secured around the back of a wearer, the sensor attachment portion pivots with respect to the securing portion so as to self-position the sensor attachment portion across (a) an upper portion of the wearer's abdomen or (b) a lower portion of the wearer's abdomen; the flexible sensor mount being configured to orient a sensor received therein to be flush with skin of the wearer when the garment is worn by the wearer and to self-adjust during the course of pregnancy.
