Abstract: A personal security alarm in the form of a wearable case containing a sonic alarm transducer, a capacitor power supply, and a manually operable trigger for completing an electrical circuit between the power supply and the alarm transducer to operate the transducer by discharging the power supply. An oscillator is electrically connected between the power supply and the alarm transducer when the trigger operates, to output a variable frequency signal. An amplifier electrically connected between the oscillator and the alarm transducer amplifies the tone signal and drives the alarm transducer with the amplified signal. The oscillator can be programmed with a predefined variable frequency signal. A charger can be coupled through the case to charge the capacitor power supply without removing the power supply from the case. If the alarm is triggered, a catch mechanism must be released to deactivate the sonic alarm prior to completion of a preset interval, thus thwarting potential deactivation of the alarm, should an attacker seize control of it.

Abstract: Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) exploiting microelectromechanical systems (MEMS) support monolithic integration with silicon based CMOS electronic thereby leveraging the cost benefits of large wafer automated silicon processing. However, nonlinear behaviour in MEMS resonators compromises their performance in some applications whilst being desired in other applications. Accordingly, the inventors have established techniques for the characterisation of the nonlinear behaviour allowing designers to tailor the design and manufacturing of the MEMS resonators to particular applications. Further, there are provided drive schemes for these MEMS resonators for improved performance with respect to the generation of pulses from such MEMS resonators.

Abstract: A vehicle computing system may implement techniques to dynamically adjust a volume and/or frequency of a sound emitted from a vehicle to warn an object ( e.g ., dynamic object) of a potential conflict with the vehicle. The techniques may include determining a baseline noise level and/or frequencies proximate to the object. The baseline noise level and/or frequencies may be determined based on an identification of one or more noise generating objects in the environment. The vehicle computing system may determine the volume and/or a frequency of the sound based in part on the baseline noise level and/or frequencies, an urgency of the warning, a probability of conflict between the vehicle and the object, a speed of the object, etc.
