  • Patent number: 10349872
    Abstract: A single, optimal, fused sensor glucose value may be calculated based on respective sensor glucose values of a plurality of redundant working electrodes (WEs) of a glucose sensor. Respective electrochemical impedance spectroscopy (EIS) procedures may be performed for each of the WEs to obtain values of membrane resistance (Rmem) for each WE. A noise value and a calibration factor (CF) value may be calculated for each WE, and respective fusion weights may be calculated for Rmem, noise, and CF for each WE. An overall fusion weight may then be calculated based on the WE's Rmem fusion weight, noise fusion weight, and CF fusion weight, such that a single, optimal, fused sensor glucose value may be calculated based on the respective overall fusion weight and sensor glucose value of each of the plurality of redundant working electrodes.

    Abstract: Enhanced short circuit damage protection by using circuit card and electronic assembly features to steer liquids, including water, onto detector arrays. In a typical implementation, a circuit card has detection elements in one or more places implemented as artwork on an outer circuit layer. The finished circuit card assembly is conformal coated with masked areas over detection artwork. When the masking is removed, channels are left behind for liquids to flow toward and pool over detection artwork. In other implementations through shaping, additive or subtractive manufacturing processes, cavities are left behind for liquids to collect over detection artwork.

  • Publication number: 20140313039
    Abstract: An electronic device includes a port for connecting the electronic device to other electronic devices and a moisture detector configured to detect an electrically conductive liquid in the first port. The moisture detector is configured to maintain a voltage on a first electrical contact of the port and to detect a short circuit between the first electrical contact and a second electrical contact of the port. The moisture detector determines that the electronic device has been exposed to an electrically conductive liquid if the monitor module detects the short circuit. The moisture detector may also put the electronic device into safe mode if it is exposed to an electrically conductive liquid.

  • Patent number: 8866624
    Abstract: Signaling systems are disclosed that indicate a change in an absorbent article, such as the presence of a body fluid. The various different signaling systems disclosed do not include any conductive elements contained on the interior of the article as were required in the past. Instead, the changes are monitored from the outer cover of the article. In one aspect, for instance, a signaling device is provided for sensing and indicating the presence of a body exudate in an absorbent article, the device including a housing and a capacitive sensor disposed within the housing, the capacitive sensor adapted to sense a change in capacitance due to an insult to the absorbent article. The signaling device can include an attachment mechanism for removably attaching the housing to the absorbent article.

  • Patent number: 8866619
    Abstract: A presence detection system (1) for detecting a presence of an object (3), particularly a person or an animal or vehicle, within an area (5) divided in detection zones (9A;9B;9C;9D) covering the area. The system comprises a movement detection device (11A;11B;11C;11D) for detecting a movement of the object. The system further comprises an electronic processing device (13) for storing information relating to a position of the object in a zone-wise way, based on a detected movement of the object. The electronic processing device is configured for determining the presence of the object within the area based on a detected movement of the object and stored information relating to the position of the object. The system is highly sensitive and highly prevents false presence detections. The invention also relates to a method for presence detection, and a lighting system comprising the presence detection system.

  • Patent number: 8854220
    Abstract: A night vision goggle system includes a housing, and an eyepiece forming a back end of the housing for viewing an object of interest. An optical field-of-view (FOV) is formed through the eyepiece, where the FOV is defined by a cone having an apex formed adjacent to an exit pupil at the eyepiece and tapering outwardly toward the object of interest. A desiccant is disposed within the housing, and located outside the FOV. The desiccant is visible through the eyepiece when viewed from outside the FOV. In addition, when the eye of a user is placed within the FOV, the desiccant is not visible through the eyepiece; and when the eye of the user is placed outside the FOV, the desiccant is visible through the eyepiece.

  • Patent number: 8836520
    Abstract: An H2S (hydrogen sulfide) monitor includes a hydrogen sulfide sensor and a moisture sensor. In some examples, the H2S monitor emits a moisture alarm if the moisture sensor detects liquid water in an amount that exceeds or approaches a moisture tolerance limit of the hydrogen sulfide sensor. In some examples, the moisture sensor prevents the hydrogen sulfide sensor from triggering a false H2S alarm caused by moisture contaminating the hydrogen sulfide sensor.

  • Patent number: 8786450
    Abstract: The invention relates to a method for identifying dirt and/or dew on components of a voltage intermediate circuit converter. According to the invention, the temporal curve of a partial discharge pulsed current is detected at least during a precharging process of an intermediate circuit capacitor of the voltage intermediate circuit converter comprising at least one capacitor, wherein a frequency spectrum is calculated from said current pulse, and wherein depending of the result, a dirt warning and/or a dew warning is activated. Thus, the degree of dirt and/or dew of said voltage intermediate circuit converter can be determined at least during a charging process of an intermediate circuit capacitor of a voltage intermediate circuit converter, thereby preventing a breakdown including the consequences thereof.

    Abstract: Example methods, apparatus, systems, and computer-readable storage media are provided to monitor a mobile device. An example method includes determining whether environmental condition data collected by a plurality of sensors of a mobile device complies with an environmental condition rule comprising thresholds associated with the environmental condition data. The environmental condition data is representative of external elements detected by the sensors. The example method includes informing a user of the mobile device of an environmental condition associated with the environmental condition data when the environmental condition data does not comply with the environmental condition rule. The example method includes performing a self-protecting procedure via the mobile device. The self-protecting procedure defined in the environmental condition rule is to protect the mobile device from the environmental condition when the environmental condition data does not comply with the environmental condition rule.
