  • Publication number: 20200178820
    Abstract: Disclosed is a method and an arrangement implementing the method for continuously estimating blood pressure. The method includes receiving an electrocardiography signal and a first photoplethysmography signal measured from the person, extracting values of a timing parameter set based on timings of the electrocardiography signal and the photoplethysmography signal, and calculating at least two intermediate estimates of the blood pressure of the person with linear regression models that model are based on different timing parameter subsets of the timing parameter set. At least one final estimate is then calculated on the basis of the intermediate estimates.

  • Patent number: 8965304
    Abstract: A multi-mode I/O circuit or cell (10) is provided for transmitting and receiving data between ICs, where each IC contains at least one of the I/O circuits. Each data link includes transmitter circuitry (12) and receiver circuitry (14). The transmitter circuitry sends data to a receiver circuitry in another IC, and the receiver circuitry receives data from a transmitter circuitry in another IC. The I/O circuit is constructed with CMOS-based transistors (e.g., CMOS or BiCMOS) that are selectively interconnected together by a plurality of switches to operate as two single-ended, current or voltage mode links, or as a single differential current or voltage mode link. In the preferred embodiment the transmitter circuitry sends data to the receiver circuitry in another IC over a first pair of adjacently disposed conductors, and the receiver circuitry receives data from the transmitter circuitry in another IC over a second pair of adjacently disposed conductors.

  • Patent number: 7336937
    Abstract: A method of compensating a direct-current offset coupled into a receiving path of a receiver, the receiving path having at least one gain factor adjustable by a gain control, which method first determines an amount of a direct-current offset present at a selected end point in the receiving path. A compensation quantity is set accordingly. In case of a forthcoming adjustment of the at least one gain factor by the gain control, the compensation quantity is then scaled with a scaling factor to prevent a direct-current step at the selected end point due to this forthcoming adjustment. The final compensation quantity is fed at a selected summing node into the receiving path. The invention is also directed to a corresponding receiver, an electronic device comprising such a receiver, a hardware component for such a receiver and to a corresponding software program product.

  • Patent number: 7239183
    Abstract: The invention relates to an active current mode sampling circuit comprising an operational amplifier (103) and at least one switched capacitor (C2, C2a, C2b). In order to reduce the power consumption of such a circuit, first switching elements (S101a, S101b, S102a, S102b) switch the switched capacitor (C2, C2a, C2b) between an input and an output of the operational amplifier (103) during charging phases ?1. Further, second switching elements (S103a, S103b, S104a, S104b) connect the switched capacitor (C2, C2a, C2b) during discharging phases ?2 to a subsequent stage (104), in order to provide a charge of the switched capacitor (C2, C2a, C2b) to the subsequent stage (104). The invention relates equally to a device (107) comprising such a sampling circuit and to a method of operating such a sampling circuit.

  • Patent number: 7061409
    Abstract: Techniques for sample rate conversion are disclosed. In one exemplary embodiment, a sample rate conversion occurs between first samples having a sample rate defined by a first clock signal and second samples having a sample rate defined by a second clock signal. Using a conversion ratio and at a first rate defined by the first clock signal, a given second sample is determined from at least one first sample. A write pointer is updated for a buffer when second samples are written into the buffer. A read pointer is updated for the buffer when second samples are read from the buffer. The second samples are read from the buffer at a second rate defined by the second clock signal. The conversion ratio is modified based on the write and read pointers.

  • Patent number: 7058463
    Abstract: An audio path is constructed to include a multi-bit sigma-delta converter for converting an N-bit digital input to an n-bit output representing an over-sampled, lower resolution n-bit version of the N-bit digital input; a formatter for converting the n-bit output to an m signal output (e.g., as a thermometer code, a SDM format or a PWM format); an m-by-m switching matric for receiving the m output signals and for reordering the m output signals, m class-D drivers individual ones of which are driven by one of the reordered m output signals for driving one of m speakers; and a dynamic element matching (DEM) block coupled to the switching matric for controlling the reordering of the m output signals driving the m class-D drivers for spreading the distortion due at least to driver-speaker pair mismatch to wide band noise. The DEM may operate to generate white noise, or it may generate shaped (colored) noise.
