Abstract: Apparatuses, systems, and techniques are described to detect one or more biological conditions. In one or more implementations, the presence of anemia can be detected in individuals. A wearable device can collect data regarding amounts of attenuation of electromagnetic radiation having one or more wavelength ranges. The amounts of attenuation of the electromagnetic radiation can be used to determine measures of biomolecules and the measures of biomolecules can be used to determine probabilities of individuals being diagnosed with anemia. Additionally, one or more implementations of a computational platform can facilitate the exchange of information between healthcare practitioners and patients regarding the diagnosis and treatment of one or more biological conditions. The computational platform can also analyze large amounts of information to generate computational models to determine probabilities of individuals being diagnosed with anemia and to determine candidate treatments for anemia.

Abstract: A voltage controlled ring oscillator (VCRO) that can operate at low voltage and provide a variable periodic output. A plurality of transistors form a ring oscillator and a selected transistor in the ring oscillator has a body which can float with respect to ground potential. The selected transistor has a threshold voltage which is controllable by a voltage applied to the transistor body. A control input is coupled to the transistor body such that the body of the transistor can be charged by the control input. Charging the body alters the threshold voltage of the transistor and thereby controls the oscillation frequency of the oscillator.

Abstract: A dynamic memory circuit in which the inherent bipolar transistor effect within a floating body transistor is utilized to store an information bit. A floating body of a storage transistor stores an information bit in the form of an electric charge. The floating body is charged and discharged via an access transistor during data write operations. The inherent bipolar transistor resident within the floating body transistor increases the effective capacitance of the floating body which acts as the storage node, and thereby enhances the magnitude of the discharge current which represents the stored information bit during read operations.
