Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure analyte or non-analyte related signal, both of which electrode include an interference domain.

A solid-state image sensor of a charge sorting method used in a time-of-flight measurement method, in which noise derived from background light, which is caused by the reflection light from the subject derived from background light is eliminated, reflection light from the subject derived from a predetermined light source, which is previously set in the solid-state image sensor, is effectively extracted as a signal component to achieve high sensitivity and low noise, which is a solid-state image sensor that is equipped with a plurality of charge-storage sections, discriminates photoelectrons generated by incoming light on the incoming timing and sort to the above-described plurality of charge-storage sections, and measures the timing of the incoming light, in which the sensor has: a plurality of capacitors that capable of conducting to the plurality of charge-storage sections; and a control section that controls a conducted state between the above-described plurality of charge-storage sections and the above-described plurality of capacitors, in which by selectively conducting the above-described plurality of charge-storage sections and the above-described plurality of capacitors by the control of the above-described control section, the difference component of charge stored in the above-described plurality of charge-storage sections is extracted.

The present invention provides a process for separating a good quality information signal from a noisy acoustic environment. The separation process uses a set of at least two spaced-apart transducers to capture noise and information components. The transducer signals, which have both a noise and information component, are received into a separation process. The separation process generates one channel that is substantially only noise, and another channel that is a combination of noise and information. An identification process is used to identify which channel has the information component. The noise signal is then used to set process characteristics that are applied to the combination signal to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify information signal. The information signal may be, for example, a speech signal, a seismic signal, a sonar signal, or other acoustic signal.

Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and / or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data.
