Bipolar plates within the system include reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, all of which are formed within a coolant-engaging or reactant-engaging surface of the plate. One or more seals are also formed on the fluid-engaging surface to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths that are defined between adjacently-placed plates. The seal—with its combination of in-plane and out-of-plane dimensions—forms a substantially hollow volume, into which a plug is placed to reduce the tendency of the seal to form a shunted flow of the coolant or reactant around the intended active area of the plate. A fluid port intersection is integrally formed with the seal and is formed to be fluidly cooperative with the volume, and is capable of accepting the introduction of a fluent precursor of the plug material such that upon curing, the precursor material forms a substantially rigid insert that continuously fills both the volume and intersection, thereby increasing the resistance of the plug to movement and the seal to shunted flow. In one form, the geometry of the fluent material injection site is such that it promotes plug anchoring within its intended location, while also providing a manufacturing aid to visually inspect for plug installation, as well as to serve as a bipolar plate stacking alignment locator and verification. |

Higher order ambisonics signal compression
Systems and techniques for compression and decoding of audio data are generally disclosed. An example device for compressing higher order ambisonic (HOA) coefficients representative of a soundfield includes a memory configured to store audio data and one or more processors configured to: determine when to use ambient HOA coefficients of the HOA coefficients to augment one or more foreground audio objects obtained through decomposition of the HOA coefficients based on one or more singular values also obtained through the decomposition of the HOA coefficients, the ambient HOA coefficients representative of an ambient component of the soundfield. |

System and method for voice actuated configuration of a controlling device
A speech recognition engine is provided voice data indicative of at least a brand of a target appliance. The speech recognition engine uses the voice data indicative of at least a brand of the target appliance to identify within a library of codesets at least one codeset that is cross-referenced to the brand of the target appliance. The at least one codeset so identified is then caused to be provisioned to the controlling device for use in commanding functional operations of the target appliance. |

System for modifying speech recognition and beamforming using a depth image
A system includes a speech recognition processor, a depth sensor coupled to the speech recognition processor, and an array of microphones coupled to the speech recognition processor. The depth sensor is operable to calculate a distance and a direction from the array of microphones to a source of audio data. The speech recognition processor is operable to select an acoustic model as a function of the distance and the direction from the array of microphones to the source of audio data. The speech recognition processor is operable to apply the distance measure in the microphone array beam formation so as to boost portions of the signals originating from the source of audio data and to suppress portions of the signals resulting from noise. |

Audio systems for providing isolated listening zones
An audio system includes a plurality of near-field speakers arranged in a listening area. A plurality of cross-talk cancellation filters are coupled to the speakers. The speakers and the filters are arranged to provide first and second listening zones in the listening area such that audio from the first listening zone is cancelled in the second listening zone and vice versa. The system also includes at least one audio source providing audio content. Volume-based equalization circuitry receives an audio signal representing audio content for the first listening zone from the audio source and controls a volume adjustment applied to the audio signal to control a volume of audio in the first listening zone. The circuitry limits attenuation or amplification of a first frequency portion of the audio signal when a volume setting differential corresponding to a difference between volume settings for the first and second zones exceeds a predetermined value. |

Guitar pick retrieval tool
The guitar pick retrieval tool is a hand tool that is configured to retrieve a pick that has fallen into the sound hole of a guitar. The guitar pick retrieval tool comprises an adhesive tip, a flexible shaft, and a handle. The handle is attached to an end of the flexible shaft. The adhesive tip is attached to the end of the flexible shaft that is distal from the handle. The flexible shaft is a semi-rigid shaft. The flexible shaft does not behave in an elastic manner. The semi-rigid nature of the flexible shaft allows the shaft to be bent into an arbitrary but stationary position which will be maintained until the flexible shaft is subsequently manipulated. The adhesive tip captures the pick by adhering to the pick when the adhesive tip is placed against the pick. |

Apparatus and method for preparing, storing, transmitting and displaying images
An imaging and display apparatus for passive displays evaluates the illumination of an input scene and incorporates data representative of such input scene within a transfer media. The transfer media may be a storage medium storing image data, illumination data and gamma information for delivery to a passive display system. The data controls the optical characteristics of the illumination source for the passive display and the gamma and tends to minimize energy requirements, to maximize contrast or shades of gray in the displayed image, and to optimize light source operation for color fidelity. The data provided the media and/or display as a video signal, modulated video signal, s-video signal, digital signal, or other signal that can be used by a passive display system to display images. |
