Abstract: Some embodiments of the disclosure provide systems and methods of detecting headphone orientation. The systems and methods described herein may be used, for example, to determine which ear cup of a pair of headphones is positioned on which ear of a user. By making this determination, stereophonic audio signals may be divided into their left audio channel signal and right audio channel signal components and transmitted to the proper ear cup. In another example, the systems and methods described herein may be used to determine when a pair of headphones are being worn on a user's head and/or are removed from a user's head. By determining when the headphones are being worn, the headphones may be able to automatically pause an audio signal and/or power off when a transition from on-head to off-head is detected.

Abstract: Disclosed herein are systems and methods for analyzing failed bodily fluid sampling. The systems and methods include providing a system having a sampling line and an access device, the access device having an inner space, wherein the sampling line is positioned in the inner space; performing a sampling event; obtaining one or more status values of the sampling event; comparing the one or more status values with at least one predetermined value corresponding to a failed sampling event; and determining whether the sampling event failed based on the comparing step. In the event of sampling failure, the systems and methods provide flushing the sampling line or a portion of the inner space of the access device via the flow controller; detecting pressure; and determining one or more possible root causes for the failure of the sampling event based on the detected pressure.

Abstract: The present disclosure provides a sensor system that includes a fluid supply, one or more supply lines, a monitor, communication lines, a sensor, a catheter and a connector assembly. The connector assembly includes a housing and a tube extending out of a distal end of the housing wherein the tube is compressed against a luer connector of the catheter to form a seal between the catheter and connector assembly.

Abstract: Embodiments of the present invention provide a blood analyte sensing system (10) that includes an integral calibrant concentration measurement system. The blood analyte sensing system includes a blood sensor (22), a calibration system and the calibrant concentration measurement system. The calibrant concentration measurement system is connected in communication with both the calibration system and the blood sensor. The calibration concentration measurement system includes a calibrant sensor (20) configured to measure a calibrant concentration in response to exposure to the calibrant. The calibration concentration measurement system is also configured to determine the analyte concentration of the patient's blood using the calibrant concentration, calibration signal and the blood signal.

Abstract: The present invention provides a blood parameter sensing system that may include a sensor, a blood access system, a flow controller and a monitor system. The blood access system may include a blood draw member having an internal configuration adapted to avoid clotting without the use of anticoagulants and under a range of flow profiles, including small volume blood draws. The flow controller may be configured to adapt to a range of access devices by using feedback from the sensor and monitor to customize flow profiles. The monitor system is configured to reduce parameter measurement error by modeling sensitivity change during system startup or reconnect.

Abstract: The present disclosure provides a sensor system that includes a blood access device, a flow controller, and an analyte sensor. The system is configured to flush or draw a volume of fluid through the blood access device at least once; determine a signal-time history corresponding to signals received from the sensor; determine a duration of a portion of the signal-time history; determine whether the duration is greater than a predetermined threshold value; and detect the occlusion in the blood access device when the duration is greater than the predetermined threshold value.
