20150137776 | DC-DC Converter with Enhanced Automatic Switching Between CCM and DCM Operating Modes - A DC-DC converter transitions between continuous conduction mode (CCM) and discontinuous conduction mode (DCM) without causing any overshoot or undershoot deviation output voltage. The DC-DC converter operates in a PWM mode in CCM. During DCM, it skips PWM pulses when a sustained negative current is detected in an output inductor. The current sensing is achieved by sampling and integrating a voltage, the sign of which is inverse to current direction. The sample and hold and integrator circuits are small, simple, and scale to high frequencies. The pulse skipping circuit automatically adjusts the duty cycle of power pulses to force a zero inductor current at the end of each pulse. | 05-21-2015 |

20100110838 | Acoustic Deterrence - A method and system of deterring mammals is disclosed involving incurring an acoustic startle response comprising the steps of selecting a target order, family, genus or species to be deterred, selecting a received level that is a predetermined level above a representative hearing threshold of the targeted mammals, and, taking transmission loss into account, transmitting an acoustic signal at a source level required to create the selected received level at a predetermined distance from the transmission point. The acoustic signal may comprise frequency components at which the aural sensitivity of the targeted mammals is greater than that of selected other animals, preventing the disturbance of the selected other animals whilst deterring the targeted mammals. In addition, a secondary conditioning sound may be played prior to the main acoustic signal to condition the mammals to avoid the main stimulus. Furthermore, using the same steps, an aversive stimulus may be played that elicits an avoidance without a startle reflex. The characteristics of these aversive sounds are those found to be unpleasant to humans. Accordingly, the aversive sound is selected to have one or more of the following psychophysical features: high roughness; low tonality; high loudness; high sharpness. | 05-06-2010 |
