Abstract: A speaker can have a main body with a generally spheroidal shape, which can be supported standing on its end. The speaker can include a subwoofer that faces forward. A plurality of mid-range drivers can be distributed around the sub-woofer, facing generally forward and radially outward. A plurality of tweeters can be distributed around the sub-woofer, facing generally forward and generally outward. The outer housing portion of the speaker can be covered with a fabric material. A user interface ring 162 can be touch sensitive to receive input, and can have a plurality of lights that can be illuminated separately to convey information to the user.

Abstract: A multi-port charger includes two or more integrated power delivery modules electrically coupled to an AC-to-DC power converter. Each of the integrated power delivery modules includes a module controller in signal communication with a digital communication bus, a USB-PD controller, a switch-mode DC-to-DC power converter which is configured to provide an adjustable output voltage to a sink device via a USB voltage bus, a first analog-to-digital converter (ADC) circuit in signal communication with the USB-PD controller and the USB voltage bus to generate a digital representation of the output voltage, and a second ADC circuit in signal communication with the USB-PD controller and the USB voltage bus to provide a digital representation of an output current provided by the switch-mode DC-to-DC power converter to the sink device.

Abstract: A noise suppression system for an electric generator having a housing including an internal combustion engine and air-cooled alternator. A fan draws ambient cooling air into the housing for cooling the alternator. The system may include an acoustically designed noise suppression shroud forming a cavity which contains a plurality of parallel flow baffles. The baffles define air flow passages there-between which receive cooling air heated by the alternator. In one system, the baffles are configured and arranged to block a straight line of sight between the entrance and exit of each passage. The baffles may each further include sound deadening materials on one or both sides in some configurations. Heated cooling air flows into the shroud and through the passages before being discharged from the housing. The shroud is operable to suppress noise produced by the cooling air discharge flow. Various shroud configurations may include additional sound proofing features.

Abstract: A portable water sport board rack includes a board holder that has an elongated back section, a curved bottom section, and a lip section that define a channel for receiving a large water sport board such as a paddle board. The bottom end of the board holder and an elongated rod are secured onto the top and bottom surfaces of a rotational unit which can rotate 360 degrees about a vertical axis. The elongated rod includes a shape and size to be removably inserted within the rod holder of a boat.

Abstract: A portable water sport board rack includes a pair of generally parallel forks each including a plurality of elongated prongs that define channels for receiving and storing water-sport boards. The forks are transversely connected via a support cross member, and an extension member connects the cross member to a rotational unit. An elongated rod is secured to the bottom of the rotational unit at an angle, and the device is secured to a boat through insertion of the angled rod into a rod holder.
