Abstract: A method of estimating a temperature at a component of a device is provided. The temperature may be used to provide thermal load management of the device. In an exemplary embodiment, a switched mode power converter includes a power converter module and a switch that controls a switching cycle of the power converter module. A signal includes a bus voltage component and an oscillating signal component at least partially caused by switching of the switch. A switch instant of the switch can be isolated. A characteristic of the oscillating signal component of the signal can be detected. For example, a first peak voltage of the oscillating signal component can be detected after the switch instant. The temperature of the power converter module is estimated using the detected characteristic of the oscillating signal component. For example, the temperature can be estimated using the first peak voltage and best-fit curve parameters in solving a linear or a quadratic equation.

Event data are stored in the data memory, the event data containing information on events occurring in the life of a user of the glucose analysis instrument and on the time of occurrence of such events. The reminder times are determined by means of a reminder time determination algorithm taking into consideration event data from at least one previous day.

Abstract: An apparatus for use with a tracheal T-tube having transversely extending first and second passages that communicate with each other. The apparatus has a body with a generally tubular shape and a channel extending between distal and proximal ends. The body has cylindrical inner and outer walls that define a wall thickness. The body can be inserted into the first passage so that the distal end lies in the second passage. The apparatus has an inflatable device operatively secured to its distal end, and means for selectively inflating and deflating the inflatable device. The body also has a tube which defines a lumen extending between the ends and fluidly connecting the inflatable device with the means for selectively inflating and deflating the inflatable device.

Abstract: Systems and methods for optimizing transmission of a plurality of data streams on a multiple-input multiple-output channel are described. The systems and methods for optimizing reduce the multiple-input multiple-output channel for each transmission scheme to an equivalent single-input single-output channel for the transmission scheme and transmit the plurality of data streams based on the single-input single-output channel for the transmission scheme. Systems and methods for optimizing the transfer of data for any number of transmit and receive antennas are described.

Abstract: A systematic method for acquiring positioning signals, such as global positioning system (GPS) signals, uses different signal detection algorithms at different stages of signal detection. For example, a method for detecting multiple positioning signals may include first detecting a first positioning signal using a robust but less sensitive signal detection method, such as non-coherent integration. Based on the signal parameter values that allow detection of the first positional signal, detecting a second positioning signal using a more sensitive method, such as coherent integration. In this manner, by capturing the strongest signal first using a robust method, signal detection parameter values common to positioning signals can be narrowed to allow subsequent signal acquisitions using a more sensitive—but computationally more intensive—method.

Abstract: A system includes an antenna array consisting of a plurality of antenna elements, a plurality of receivers to process the signals from the antenna elements of the antenna array, and a combiner to combine receiver outputs so as to minimize the effect of undesirable signals such as multipath or interference while maintaining a nominal gain in the direction of the desired signal. The combiner takes into account variation or uncertainty in the assumed antenna array response, such as imprecise knowledge of the angle of arrival and uncertainty in the array manifold and multiplicative uncertainties due to gain variations between receivers, as well as non-uniformity in the response due to coupling between elements and coupling with the antenna structure. This system is applicable to antenna arrays with non-uniform responses, such as closely spaced arrays in which the coupling between elements is significant.

Abstract: A method for detecting a positioning signal includes (a) correlating a segment of a received positioning signal with a reference signal of a selected code phase and frequency to obtain a correlation value, (b) if the correlation value is less than a predetermined minimum, assigning the correlation value to the predetermined minimum, and (c) accumulating the correlation value in a sum of correlation values obtained using other segments of the received positioning signal. In addition, the correlation value may be reduced by a predetermined value, which is preferably an expected mean value for a noise component in the segment of the received positioning signal.

Abstract: On a carrier layer there are arranged several test layers which are at least partly in fluid contact with one another, enabling liquid exchange. On the carrier layer are arranged an application zone, a detection zone for the production of a detectable signal characteristic of the analytical determination, which contains at least one said test layer which is a reaction layer, and an absorption zone with a test layer which is an absorptive layer of an absorbent material, wherein the reaction layer and absorption zone are positioned next to each other. Between the application and the absorption zone is a capillary-active transport path on the carrier layer which connects the application zone and the absorption zone. The reaction layer is arranged parallel to the transport path between the application zone and the absorption zone in such a manner that it is in liquid contact with a liquid transported in the transport path.
