    Abstract: Described are various embodiments of a point-of-care testing (POCT) system, analyzer and method for measuring quantities of at least two analytes in a blood sample, for example bilirubin and hemoglobin. The system comprises an analyzer and a removable cartridge. The removable cartridge comprises an optical chamber configured for receiving the blood sample. The analyzer comprises a receptor for receiving the removable cartridge, a first and second set of incident electromagnetic radiation (EMR) for example two broadband LEDs, an EMR dispersive element for example a reflective grating, a photo diode array detector, and a processor. The two EMR sources are implemented in such a way so that the spectral wavelength range of EMR emerging from the blood is expanded, and the effect of stray EMR is mitigated. The expanded wavelength range and the mitigation of stray EMR allows the analyzer to measure quantities of the analytes in lysed or unlysed blood.

    Abstract: A method for preserving a frame check sequence (FCS) of a data frame during backscatter communication is provided. The method comprises: receiving a transmitted signal including a transmitted data frame, wherein the transmitted data frame includes a first data sequence and the FCS; determining a cyclic redundancy check (CRC) preservation sequence based on a backscattering tag data sequence, a bit-length of the backscattering tag data sequence, and a given CRC algorithm; and backscattering the transmitted signal to form a backscattered signal including a backscattered data frame, wherein the backscattered data frame includes a second data sequence and the FCS. The second data sequence includes a transmitted data sequence, an encoded tag data sequence and the CRC preservation sequence. The CRC preservation sequence preserves the FCS of the transmitted data frame in the backscattered data frame. The FCS is usable to detect communication errors in the backscattered data frame.

    Abstract: A hand vacuum cleaner has a main body housing a suction motor, an air treatment member having a front end and a rear end with a central longitudinal axis extending between the front and rear ends and a bleed valve having a bleed air flow path that extends from a bleed air inlet to a bleed air outlet. The hand vacuum cleaner has right and left laterally opposed sides that are spaced apart in a direction transverse to the central longitudinal axis, and the bleed air inlet and the bleed air outlet are transversely spaced apart.

    Abstract: Systems and methods for controlling heating of a hydrocarbon medium using a signal generator and a load having frequency and time dependent impedance. A desired heating life cycle is determined. A current state is determined using a model of the medium and the load. A desired operational state is determined from the current operational state and the desired heating life cycle. The desired operational state is selected to maximize a fit between the desired operational state and the desired heating life cycle. Desired signal generator control settings are determined for the signal generator in order to achieve the desired operational state. An output signal is generated using the signal generator by applying the at least one desired signal generator control setting to the signal generator. The output signal is defined to excite the load and thereby heat the hydrocarbon medium.
