Abstract: A lancing device has a domed structure that can be depressed by application of a force by a user's finger so as to expose the tip of a needle. The domed structure is configured to move from a non-depressed state to a depressed state in a manner that allows for the piercing of the user's finger. The domed structure may then recoil to its original, non-depressed position upon the user ceasing to apply the force. Other embodiments of a lancing device are disclosed.

Abstract: A battery-operated electronic device, such as, e.g., a continuous glucose monitoring (CGM) transmitter, has a switch disconnect circuit that reduces battery discharge while the device is stored and/or in “shelf mode.” The device has two externally-accessible activation pads each configured to contact a same electrical conductor positioned in packaging for the device that causes the switch disconnect circuit to disconnect the battery from device electronics while the device is in the packaging. Upon removal of the device from the packaging, the two activation pads no longer contact the electrical conductor, causing the switch disconnect circuit to automatically connect the battery to the device electronics. Methods of reducing battery discharge in a battery-operated electronic device and other aspects are also described.

Abstract: Continuous glucose monitoring (CGM) may include applying a periodic excitation signal via an electrode of a CGM sensor to human interstitial fluid to drive an oxidation/reduction reaction, and measuring the current through the electrode. In some embodiments, the measured current is sampled and digitized, and various harmonics of the excitation signal's fundamental frequency are extracted. A set of relationships of at least two harmonics each is generated from the spectral amplitudes of a set of pairs, triplets, etc., of the harmonics, and the set of relationships is mapped to a glucose concentration such as based on the contents of a harmonic relationship database having a pre-existing set of harmonic relationships and glucose concentrations to which those sets of harmonic relationships correspond, for example. Numerous other embodiments are provided.

Abstract: A biosensor inserter includes a push member with a push element, a contact member including a latch, a transmitter carrier supporting a transmitter and sensor assembly, and a pivot member having a latch end, the pivot member supporting an insertion device during biosensor insertion. In operation, the push member is telescoped axially by the user relative to the contact member, which is provided in contact with a user's skin. This pushes the push element against the pivot member and translates the transmitter carrier during insertion of the biosensor. During a first portion of a stroke of the insertion device, insertion of the biosensor is accomplished, and the pivot member is prevented from pivoting. In a second portion of the stroke, after latch end moves past the latch, the pivot member is allowed to pivot and the insertion device is retracted. Other system and method embodiments are provided.

Abstract: A biosensor system, method and apparatus are provided for implementing threshold based correction functions for biosensors. A primary measurement of an analyte value is obtained. A secondary measurement of a secondary effect is obtained and is compared with a threshold value. A correction function is identified responsive to the compared values. The correction function is applied to the primary measurement of the analyte value to provide a corrected analyte value. The correction method uses correction curves that are provided to correct for an interference effect. The correction curves can be linear or non-linear. The correction method provides different correction functions above and below the threshold value. The correction functions may be dependent or independent of the primary measurement that is being corrected. The correction functions may be either linear or nonlinear.

Abstract: Apparatus and methods are operative to probe the condition of a sensor either initially, at any point thereafter or continuously during a continuous sensor operation for measuring an analyte in a bodily fluid (such as performed by, e.g., a continuous glucose monitoring (CGM) sensor). Results of the probe may include calibration indices determined from electrical signals obtained during the probe. The calibration indices may indicate whether in-situ adjustment of the sensor's calibration should be performed either initially and/or at random check points. Probing potential modulation parameters also may be used during analyte calculations to reduce the effects of lot-to-lot sensitivity variations, sensitivity drift during monitoring, temperature, interferents, and/or the like. Other aspects are disclosed.

Abstract: A test sensor for determining an analyte concertation in a biological fluid comprises a strip including a fluid receiving area and port-insertion region. A first row of optically transparent and non-transparent positions forms a calibration code pattern disposed within a first area of the port-insertion region. A second row of optically transparent and non-transparent positions forms a synchronization code pattern disposed within a second area of the port-insertion region. The second area is different from the first area. The synchronization code pattern corresponds to the calibration code pattern such that the synchronization code pattern provides synchronization of the serial calibration code pattern during insertion of the port-insertion region into the receiving port of the analyte meter.
