Abstract: A modulation device includes a substrate, an electrostatic discharge protection element, an electronic element, and a driving element. The substrate has an active region. The electrostatic discharge protection element is arranged around the active region. The electronic element is disposed in the active region. The driving element is electrically connected to the electronic element.

Abstract: A system may include a first acoustic event detection (AED) component configured to detect a predetermined set of acoustic events, and include a second AED component configured to detect custom acoustic events that a user configures a device to detect. The first and second AED components are configured to perform task-specific processing, and may receive as input the same acoustic feature data corresponding to audio data that potentially represents occurrence of one or more events. Based on processing by the first and second AED components, a device may output data indicating that one or more acoustic events occurred, where the acoustic events may be a predetermined acoustic event and/or a custom acoustic event.

Abstract: An electrical generating device includes one or more ram water pumps for pumping water from a lower water reservoir into an upper water tower, a water paddling device having a rotatable housing located below the water tower and coupled to an electric generator to generate an electrical energy, and a control device having a casing for directing the water to rotate the housing and having a pivotal valve member to control a flowing of the water through the casing and into the housing, an adjusting element is attached to the casing and engaged with the valve member for pivoting and adjusting the valve member relative to the casing and to control the water to flow into the housing.

Abstract: An electrical generating device includes a higher gear and a lower gear rotatably mounted between a higher water tower and a lower water reservoir, a chain engaged with the gears and having a number of plates, the water tower includes an outlet tube directed to the plates for supplying the water to move the plates downwardly and to rotate the chain and the gears, an electric generator is coupled to the higher gear for being actuated to generate an electrical energy, and one or more ram water pumps are used for pumping the water from the water reservoir upwardly into the water tower without electrical energy, the higher gear is adjustable to different rotational speeds with an adjustable magnetic device.
