20130101136 | WEARABLE DIRECTIONAL MICROPHONE ARRAY APPARATUS AND SYSTEM - A wearable microphone array apparatus and system used as a directional audio system and as an assisted listening device. The present invention advances hearing aids and assisted listening devices to allow construction of a highly directional audio array that is wearable, natural sounding, and convenient to direct, as well as to provide directional cues to users who have partial or total loss of hearing in one or both ears. The advantages of the invention include simultaneously providing high gain, high directivity, high side lobe attenuation, and consistent beam width; providing significant beam forming at lower frequencies where substantial noises are present, particularly in noisy, reverberant environments; and allowing construction of a cost effective body-worn or body-carried directional audio device. | 04-25-2013 |
20130101141 | DIRECTIONAL AUDIO ARRAY APPARATUS AND SYSTEM - A directional transducer array system comprising a plurality of transducers with mathematical sequence spacing mounted on an array tile or host device. In an embodiment, the invention allows the construction of a receiving or transmitting, tiled (modular) directional audio array while simultaneously retaining desirable directional characteristics, improving gain, and limiting negative impacts on side lobe attenuation as the array is scaled (i.e. identical or similar tiles are added to or subtracted from the array); and allows the construction of a receiving or transmitting directional audio array that is light weight and robust enough to be used in body-worn, body-carried, vehicular, and fixed installations. | 04-25-2013 |
20130216083 | DIRECTIONAL AUDIO WAVEGUIDE ARRAY - A directional waveguide array apparatus can transmit and/or receive airborne or fluid-borne audio with the appropriate selection of transducers. The present invention advances directional waveguide arrays by allowing construction of a directional audio device with desired frequency bandwidths, array patterns, and gain by appropriate geometric configurations of the array of waveguide channel ports, as well as dimensioning and configuration of waveguide channel and chamber parameters. Embodiments of the present invention enable increased immunity to environmental noises, temperature, and humidity; low cost of construction; high reliability; simplicity of operation; very low power consumption; real-time steering of directivity (interference) pattern; wide range of audio powers that can be transmitted or received; and interchangeable transducer types. | 08-22-2013 |

20100150748 | Method of Installing a Permanent Magnet Motor in a Cooling Tower and a Shroud Used in Connection Therewith - A method comprises providing a motor with a stator comprising a plurality of laminations stacked side to side to form a contiguous stator core with each of the laminations having a plurality of radial fins projecting outward from a periphery of the lamination, and a rotor with permanent magnets spaced about the rotor configured to synchronously magnetically couple with a rotating magnetic field in the stator. The method further comprises providing a cooling tower with a fan disposed therein having a shaft extending from a center of the fan for rotating the fan. The motor is installed in the cooling tower such that the rotor of the motor is coupled directly to the fan shaft and rotates the fan when the motor is energized during normal operation of the cooling tower. | 06-17-2010 |

20140283373 | Lamination for a Permanent Magnet Machine - A method includes forming a lamination that may be used in a rotor of an interior permanent magnet motor or further processed for use in a line-start interior permanent magnet motor. The lamination has been optimized for low cogging, minimal usage of magnet material, and maximum torque per ampere and may be further processed to include rotor bars slots to allow the lamination's use in connection with an LSIPM. In accordance with the method, the lamination is formed with magnet slots that are radially inward of the outer diameter. The magnet slots are formed in a plurality of V-shaped arrangements. Each V-shaped arrangement has a leading edge and a trailing edge. The leading edge and trailing edge are arranged such that when the leading edge aligns with a stator tooth, the respective trailing edge is generally not aligned with a stator tooth. | 09-25-2014 |

20100217526 | METHOD FOR SIMPLE OPTICAL AUTONOMOUS REFUELING SYSTEM - The present inventions provides for a system and method to facilitate dynamic spatial positioning of a second vehicle in relation to a first vehicle autonomously. The system includes a first vehicle, a second vehicle, a light pattern located on the first vehicle, an imaging system, and a processor. The imaging system is located on the second vehicle and is operable to receive a signal from the light pattern while having a clear line of sight with the light pattern. Furthermore, the processor is in communication with the imaging system, such that the processor is operable to determine the spatial positioning between the first vehicle and the second vehicle. Additionally, the processor is further operable to communicate instructions to the second vehicle, such that the second vehicle can achieve the desired spatial positioning autonomously. | 08-26-2010 |
