Abstract: Systems and methods are described for monitoring usage of a medicament dispenser—particularly an inhaled medicament dispenser. The usage monitoring device is configured to emit a detection signal responsive to receiving a request to locate the medicament dispenser. The detection signal alerts presence of the medicament dispenser to the user of the medicament dispenser. The usage monitoring device can be embodied as an attachment configured to be selectively coupled to one of a variety of different inhalers including, for example, a Diskus-type inhaler and a Respimat-type inhaler.

Abstract: Systems and methods are described for monitoring usage of a medicament dispenser—particularly an inhaled medicament dispenser. While operating in a low-power mode, a first sensor is monitored for a signal indicative of handling of the medicament dispenser by a user. In response to detecting such handling, the device exits the low-power mode and begins to monitor a second sensor for a signal indicative of dispensing of the medicament. The usage monitoring device can be embodied as an attachment configured to be selectively coupled to one of a variety of different inhalers including, for example, a Diskus-type inhaler and a Respimat-type inhaler.

Abstract: An audio system can include an amplifier having two parallel drivers, one having common source transistors and one having common drain transistors, also called source following. At low signals, the source followers dominate the open-loop gain signal path, while large signals cause the common source transistors to be dominant. At low signal amplitudes, the common source transistor gain is reduced and the common drain transistors provide the load current. At a pre-determined level of signal amplitude, the common source transistors take over and provide the current load. A calibration system for a DAC is also provided. The calibration system measures individual cell performance in the DAC, then stores its digital equivalent in a coefficient storage. Then, a quantizer can refer to the stored coefficients when selecting the appropriate final quantized digital value.

Abstract: An RF power amplifier system comprises an amplitude control loop and a phase control loop. The amplitude control loop adjusts the supply voltage to the power amplifier based upon the amplitude correction signal indicating the amplitude difference between the amplitude of the input signal and an attenuated amplitude of the output signal. The phase control loop adjusts the phase of the input signal based upon a phase error signal indicating a phase difference between phases of the input signal and the output signal. The phase control loop may comprise one or more variable phase delays introducing a relative phase delay to allow the phase differences between the input and output signals of the PA circuit to be within a range compatible with a phase comparator generating the phase error signal, and a low frequency blocking module that removes the larger extent, lower frequency components of the phase error signal.

Abstract: A circuit and method for providing a periodic clock signal, such as a high frequency clock signal. In one example, the circuit may include a phase locked loop circuit having a voltage controlled oscillator, the voltage controlled oscillator having a voltage input, a calibration input, and a clock signal output; and a logic circuit for dynamically calibrating an operating frequency of the phase locked loop during operation of the phase locked loop. In one embodiment, the logic circuit may compare an input voltage into the voltage controlled oscillator against a reference voltage, and if the input voltage is lower than the reference voltage, the logic circuit decreases the operating frequency of the phase locked loop circuit. The logic circuit may compare an input voltage into the voltage controlled oscillator against a reference voltage, and if the input voltage is higher than the reference voltage, the logic circuit increases the operating frequency of the phase locked loop circuit.

Abstract: Wireless devices transmit and receive radio signals based upon reference frequencies generated by crystal oscillators. If the reference frequencies of the transmitter and the receiver are different, the radio signals may not be received properly or may not be received at all. A measurement circuit measures the amount of error or signal corruption in the radio signals due to the reference frequency offset between the transmitter and the receiver. A frequency offset circuit generates an offset operating frequency in the transmitter or the receiver to align or calibrate the operating frequencies of the devices.

Abstract: A transmitter digital signal processor (DSP) circuit has a transmit frequency represented by n-bit data output from a look up table (LUT). The n-bit data is outputted to an n-bit accumulator structured to overflow at a rate based on the output n-bit data to output a phase. The circuit further has device structured to add an n-bit signed constant to the accumulator to offset the frequency represented by the n-bit data output from the LUT. A transceiver on a semiconductor chip may include as part of a transmitter circuit, a transmit DSP circuit that has the LUT, accumulator and device providing an n-bit signed constant to the accumulator to offset a transmit frequency in order to allow a receiver circuit on the transceiver to communicate directly with the transmitter circuit, and thus allowing testing of the transceiver.
