摘要： A boat having a deck and a hull includes a suspension for suspending the deck with respect to the hull. Sensors are employed to determine motion of the deck, with a controller adjusting the suspension such that it maintains the pose of the deck with respect to an inertial reference and with respect to pitch, roll, and heave of the deck.

摘要： An improved in-wall speaker assembly (16) providing better performance and less intrusion than prior art speakers. The speaker assembly (16) is oriented such that the driver fires vertically, parallel to the wall studs (25a, 25b), rather than horizontally and perpendicular to the wall studs (25a, 25b). The cone and surround of the speaker assembly are generally rectangular and/or conform to the area available between studs (25a, 25b). Additionally, the cone is not attached to the voice coil, but is connected to the voice coil by a shaft which transmits the energy from the voice coil to the cone. In another aspect of the invention, the cabinet or housing includes two housings (16, 22).

摘要： A lidar-based 3-D point cloud measuring system (150) and method. An example system includes a base (158), a housing (152), a plurality of photon transmitters and photon detectors contained within the housing, a rotary motor that rotates the housing about the base, and a communication component that allows transmission of signals generated by the photon detectors to external components. The rotary component includes a rotary power coupling configured to provide power from an external source to the rotary motor, the photon transmitters, and the photon detectors. In another embodiment, the photon transmitters and detectors of each pair are held in a fixed relationship with each other. In yet another embodiment, a single detector is 'shared1 among several lasers by focusing several detection regions onto a single detector, or by using a single, large detector.

摘要： Systems and methods for optimizing speaker performance. The system (30) includes a self-contained speaker unit (32) that includes a speaker (56), an amplifier (54) coupled to the speaker (56) , and a processor (50) coupled to the amplifier (54). The processor (50) receives a first sound signal from a receiver (36) and a second sound signal from a microphone (34) , processes the first sound signal based on a plurality of parameters, outputs the processed sound signal to the speaker (56) , and generates a video signal based on the second sound signal. A wireless remote control (42) allows a user to manipulate the parameters. The processor (50) generates a test sound signal and outputs it to the receiver (36) . The receiver (36) processes the test sound signal and returns it to the processor (50) for output through the speaker (56). The video signal includes a graphical user interface having a frequency response graph of the second sound signal and an eight band equalizer.
