Abstract: Computer eyewear for reducing the effects of Computer Vision Syndrome (CVS). In one embodiment, the eyewear comprises a frame and two lenses. In some embodiments, the frame and lenses have a wrap-around design to reduce air flow in the vicinity of the eyes. The lenses can have optical power in the range of approximately +0.5 to +2.5 diopters for reducing accommodation demands on a user's eyes when using a computer. The lenses can also include prismatic power for reducing convergence demand on a user's eyes when sitting at a computer. The lenses can also include a partially transmissive mirror coating, tinting, and anti-reflective coatings. In one embodiment, a partially transmissive mirror coating or tinting spectrally filters light to remove spectral peaks in fluorescent or incandescent lighting.

Abstract: In a low frequency transducer system a multi-compression chamber, an inverse horn structure is employed in combination with a resonance-distortion filter chamber. The filter chamber effectively expands the effective enclosure volume at low frequencies and connected to one of the compression chambers filter parasitic resonances and distortion and allowing the system to more efficiently reproduce low frequencies while being able to use smaller diameter transducers and maintaining good system sensitivity. Compression chambers are organized for constant or continuous compression on a section-by-section basis throughout the inverse horn system.

Abstract: A single-ended planar transducer device for generating a sound signal based on an electrical signal comprising at least two primary rows of primary magnets, at least one return row of at least one return structure, a diaphragm, a conductive trace formed on the diaphragm, and a frame. The frame supports two primary rows to define at least one core set comprising no more than two primary rows. A primary magnetic field is established between the primary rows in the at least one core set. The frame supports at least one return row adjacent to the at least one core set. A return magnetic field is established between each return row and any primary row adjacent thereto. A first portion of the trace is arranged at least partly within each primary magnetic field and a second portion of the trace is arranged at least partly within each return magnetic field.

Abstract: Various embodiments of computer eyewear include optical treatments to provide a relaxing, calming, and soothing light environment for the eye. Certain embodiments of computer eyewear include a frame and two lenses. Each lens in these embodiments has optical power in the range from about +0.1 to about +0.5 diopters, and provides spectral filtering characterized by a transmission curve. The transmission curve includes a stop band portion positioned between about 320 nm to about 400 nm, a first plateau region positioned between about 420 nm to about 450 nm, a ramp region positioned between about 470 nm to about 560 nm, and a second plateau region positioned between about 570 nm to about 680 nm.

Abstract: Modular pack systems that may be used for backpacking, biking, hunting, fly fishing, or other indoor or outdoor activities are disclosed. In one embodiment, a system is adjustable to fit different user torso sizes and includes attachment structures that may removably secure various detachable packs, pouches, or containers for different items needed. The attachment structures are generally spaced apart evenly in groupings throughout various locations on shoulder straps, a torso structure, and/or waistband, providing for standardization of pouches for attachment to the harness. Certain embodiments may also include hydration and waist packs, fabric flex points on shoulder straps that provide more flexibility in fitting over the shoulders, an adjustable lumbar support system for additional back support for the wearer, and/or flaps on the waistband for securing excess belt webbing after adjustment by the wearer.

Abstract: Disclosed is a loudspeaker apparatus having at least one support surface provided therein adjacent to a complaint surround for providing lateral support thereto, the surround mounting the diaphragm of the speaker to a speaker frame for permitting longitudinal movement of the diaphragm with respect to the frame. The support surface may be used with a variety of surrounds. A second support surface may also be provided. The support surfaces may be contoured to achieve a desired response from their engagement with the surround. A negative air spring is formed from a pair of opposed support surfaces contoured to form a necked region therebetween for deformingly engaging a surround formed as a resilient member. The negative air spring negatively balances, or counterbalances the diphragm against the box pressures with the enclosure. The resilient member is formed as a tube for containing a fluid such as air therein. The pressure within the resilient member is controlled in response to a variety of parameters.
