Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: Implementations are disclosed for monitoring a state or change in state of a physiological parameter based on measured impedance data. In certain implementations, no images are reconstructed from the impedance data. In certain implementations, a metric (e.g., distinguishability, likelihood ratios, and so forth) may be computed and compared to reference metrics or thresholds, such as for changes over time or in comparison to a standard to determine the presence or absence of a physiological state of interest or of a change in such state.

Abstract: One system includes a pattern generator that generates one or more excitation patterns suitable for probing a hydration level of a tissue of a subject at one or more depths from a surface of the subject into an interrogation region. Each of the excitation patterns has a spatial sensitivity at one of the one or more predetermined depths. A data analysis module receives one or more measured responses of the subject at a plurality of electrodes to excitation applied by the plurality of electrodes based on the one or more excitation patterns and determines one or more hydration changes at the one or more depths within the subject based on the measured responses. Each of the measured responses corresponds to the one of the one or more predetermined depths for which the applied excitation pattern has spatial sensitivity.
