  • Patent number: 8164468
    Abstract: A system and method is described for rapid charging and power management of a battery for a meter. A charger component is operably associated with the meter and is capable of executing a rapid charge algorithm for a rechargeable battery. The algorithm includes monitoring for a connection to an external power source and implementing a charging routine of a battery at a first charge rate and then at a second charge rate. The second charge rate is lower than the first charge rate. A temperature rise in the rechargeable battery due to the first charge rate has a negligible heat transfer effect on the fluid sample. The meter can also include a power switch for controlling current flow to a battery fuel gauge. The power switch is open when the meter enters into a sleep mode. The state of battery charge is determined after the meter exits the sleep mode.

  • Patent number: 8135450
    Abstract: New methods and systems for noninvasive glucose monitoring and sensing with electromagnetic waves or ultrasound are disclosed. The methods are based on absolute or relative measurement of tissue dimensions (or changes in the dimensions) including, but not limited to: thickness, length, width, diameter, curvature, roughness as well as time of flight of ultrasound and optical pulses and optical thickness, which change with changing blood glucose concentrations. By measuring noninvasively absolute or relative changes in at least one dimension of at least one tissue or tissue layer or absolute or relative changes in time of flight of ultrasound or optical pulses, one can monitor blood glucose concentration noninvasively.

  • Publication number: 20120059236
    Abstract: An implantable device for constant collection and dosage of glycemia with real-time monitoring, with no need of external collection by punctioning which is constituted by a metal compartment, hermetically sealed with the cap, containing at least a micro-computerized mini-center fed by the battery or similar, which is externally rechargeable. The device contains a sensor which collects a portion of the circulating blood and reads glycemia levels in real time, sending reading information through the transmission component. The device is connected to an inlet catheter with its collecting edge duly implanted by means of punctioning at the subclavian vein, to deviate a small flow of blood to pass through within said dosage and monitoring device, thus allowing the sensor to verify the glycemic dosage and following its natural course by exiting the exit catheter through the outlet edge, thus returning to the blood current within said subclavian vein.

  • Publication number: 20120059235
    Abstract: An approach to instrumentation and telemetry of physiological and physical parameters of an animal and its environment has particular application to horses. This approach improves the effectiveness of one or more of evaluation, diagnosis, care conditioning or monitoring of animals because it does not require use of restrictive equipment such as force plates or treadmills, and it can provide objective and quantitative data that is complete, accurate, precise and reproducible, and this data can be obtained under real-world conditions, for either or both of more or less real-time or continuous processing of data to perform the monitoring or diagnosis. That is, in such an approach objective and quantitative data can be collected under real-world conditions and this data can be processed and the information can be displayed in a form that is familiar to experts in real-time locally, or can be stored for subsequent retrieval or transmitted for remote review.

  • Patent number: 8128562
    Abstract: Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as ischemia, pH changes, temperatures changes, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system replaces some or the entire data stream continually or intermittently including signal estimation methods that particularly address transient signal artifacts. The system is also capable of detecting the severity of the signal artifacts and selectively applying one or more signal estimation algorithm factors responsive to the severity of the signal artifacts, which includes selectively applying distinct sets of parameters to a signal estimation algorithm or selectively applying distinct signal estimation algorithms.

  • Publication number: 20120053436
    Abstract: A limited-use blood glucose meter includes a printed circuit board assembly that includes a power source, a strip port, a strip reading device, a controller device, a bi-stable display, and a display controller. The strip reading measures a reaction between a blood sample present on the blood glucose test strip and the blood glucose reagent, generates a blood glucose signal, and calculates a blood glucose level. The controller device receives the blood glucose level from the strip reading device. The controller device provides display instructions to the display controller and the display controller provides drive voltages to the bi-stable segments such that the bi-stable segments persistently display the most-recent blood glucose level. The strip reading device performs a predetermined number of blood glucose tests and calculates a blood glucose level only for blood glucose strips associated with the disposable blood glucose meter.

  • Patent number: 8118741
    Abstract: The present invention includes a method and device for warning of hypoglycaemic attacks, which is a big problem for especially diabetics, who are in insulin treatment. It is estimated that about 1 million people have a decreased quality of life as a result of hypoglycaemic attacks. The invention collects EEG signals from people, who must be supervised and analyses these in order to detect characteristic changes in the EEG signals, which occurs in advance of a hypoglycaemic attack. In a preferred embodiment the EEG signals are collected with subcutaneously placed electrodes and the signals are lead via wires drawn under the person's skin to a similar subcutaneously placed signal processing unit. The signal processing analyses the EEG signals and when the pre-seizure characteristics signal changes are detected, a warning signal is given to the person from an alarm giver build into the signal processing unit, e.g. in form of a vibrator.

  • Patent number: RE43316
    Abstract: A diabetes management system for predicting a future blood glucose value of a patient and for recommending a corrective action to the patient when the future blood glucose value lies outside of a target range. The system includes a patient-operated apparatus for measuring blood glucose values and for storing data relating to insulin doses administered to the patient. The apparatus predicts the patient's future blood glucose value based upon the patient's current blood glucose value, the fraction of insulin action remaining from the insulin doses, and the patient's insulin sensitivity. The apparatus also determines the corrective action for the patient when the predicted blood glucose value lies outside of a target range. The system also includes a physician computer in communication with the apparatus for receiving the blood glucose values and insulin dose data and for calculating an adjusted insulin sensitivity for use in subsequent predictions.
