    • A water and bubble toy includes a water projecting assembly and a bubble generating assembly. Water is stored in a water reservoir located in a rear handle of the toy while bubble solution is stored in a detachable reservoir. The water generating assembly is operated by a lever located toward an upper end of the toy. When the lever is pulled, the lever activates a first pump that expels water from the toy. The bubble generating assembly is operated by a finger trigger that activates an electric motor, which powers a second pump and a fan. The second pump pumps bubble solution to a ring and the bubble solution coats the ring. The fan blows air through the ring and helps generate and propel bubbles from the ring.

    • The present disclosure describes techniques that may provide more accurate estimates of arterial oxygen saturation using pulse oximetry by switching between a wavelength spectrum of at least a first and a second light source so that the arterial oxygen saturation estimates at low (e.g., in the range below 75%), medium (e.g., greater than or equal to 75% and less than or equal to 84%), and high (e.g., greater than 84% range) arterial oxygen saturation values are more accurately calculated. In one embodiment, light emitted from a near 660 nm and a near 900 nm emitter pair may be used when the arterial oxygen saturation range is high. In another embodiment, light emitted from a near 730 nm and a near 900 nm emitter pair may be used when the arterial oxygen saturation range is low. In yet another embodiment, light emitted from both a near 660 nm-900 nm emitter pair and light emitted from a near 730 nm-900 nm emitter pair may be used when the arterial oxygen saturation range is in the middle range. Priming techniques may also be used to reduce or eliminate start up delays of certain oximetry system components.

    • A physiological monitoring system may use photoacoustic sensing to determine one or more physiological parameters of a subject. The photoacoustic system may use two light sources (e.g., a high power pulsed laser diode and a continuous wave laser diode) to generate acoustic pressure signals in a subject. One or more light sources (e.g., the high powered pulsed laser diode) may provide a high signal-to-noise ratio. The high signal-to-noise ratio signals may provide high sensitivity for physiological measurements (e.g., cardiac output and temperature measurements). The photoacoustic system may use high powered light sources in combination with other light sources to improve physiological measurements.

Physiological parameters, such as venous oxygen saturation and arterial oxygen saturation, may be determined based on the values.

    • A physiological monitoring system may perform an optical measurement of a subject to assist a photoacoustic analysis of the subject. For example, an oblique-incidence diffuse reflectance measurement, photon density wave measurement, or other optical measurement may be used to determine one or more optical properties of a subject. Accordingly, the one or more optical properties may be used to determine an optical fluence at a region of the subject. In some arrangements, a physiological monitoring system may include an oximeter, and may use a calculated blood oxygen saturation value to assist a photoacoustic analysis. Photoacoustic analysis may include determining one or more physiological parameters based on a detected acoustic pressure response of a subject to a photonic signal via the photoacoustic effect.

Whether the first logical address is mapped to a null physical address is then determined according to the address link table. When the first data is the predetermined data and the first logical address is not mapped to the null physical address according to the address link table, the address link table is modified to map the first logical address to the null physical address.
