Abstract: An audio engine is provided for acoustically rendering a three-dimensional virtual environment. The audio engine uses geometric volumes to represent sound sources and any sound occluders. A volumetric response is generated based on sound projected from a volumetric sound source to a listener, taking into consideration any volumetric occluders in-between. The audio engine also provides for modification of a level of detail of sound over time based on distance between a listener and a sound source. Other aspects are also described and claimed.

Abstract: A ceiling electrical box can include a housing and a bracket. The housing is defined by a rear wall at a first end, at least one sidewall, and an opening at a second end and includes a first emboss tab, a second emboss tab, a pair of screw holes, a pair of first bores, and a pair of second bores. The bracket includes a first portion, a second portion, a pair of first threaded apertures, and a pair of second threaded apertures. The bracket can include a third portion and a fourth portion extending on a first plane of the first portion. The ceiling electrical box can also include a pair of first fasteners to attach the housing to the bracket and a pair of second fasteners to engage the bracket through the housing, the second fasteners configured to receive a fixture plate for a ceiling fixture.

Abstract: Provided herein are wireless earbud systems that include a pair of earbuds connected at opposite ends of a lanyard. One or both earbuds may be connected to the lanyard by a releasable connection, that allows the (or each) earbud to be selectively attached to, detached from and reattached to the lanyard (or other lanyard). The earbuds contain electronics, but the lanyard is free of electrical connections. In certain examples, the wireless earbud system includes multiple lanyards of the same or different styles, colors, materials, or the like. The releasable connection allows the first and second earbuds to be selectively attached and detached from any one of the multiple lanyards, to allow a user to selectively choose and replace lanyards and/or earbuds. Each earbud may include a respective magnet (or one earbud includes a magnet and the other includes a magnetically attractable material) arranged such that the earbuds are magnetically attracted to each other, when brought together.

Abstract: A stratified or segmented composite data structure can be formed by selecting a group of data entities, stratifying or segmenting them according to attributes, and assigning relative weights to the components based on their stratified or segmented positions. The attributes are selected from a universe of possible values. Further positive and negative biases can be applied at any arbitrary point or position, including to individual data entities, groups of arbitrarily selected data entities, or arbitrary positions.

Abstract: A system for withdrawing samples of fluids comprises a pitot tube assembly, a flow sensor to measure a flow rate of the sample, and a pump connected to the pitot tube assembly to withdraw a sample, wherein the system is configured to match a sample flow velocity to the flow velocity sensed by a flow sensor on a pitot wand. The pitot tube assembly comprises a housing with a sample outlet and a return sample inlet, an extendable/retractable pitot wand within the housing, wherein the pitot wand includes a passage extending the length thereof to transfer a sample from a pitot tube end to a sealed compartment in the housing connected to the sample outlet; wherein the return sample inlet is connected to a passage in the housing leading to an outlet from the housing, and a flow sensor on an end of the pitot wand.

Abstract: A method and system for taking a sample of ballast water. The method includes withdrawing a sample of ballast water via a tube inserted in a ballast water pipe, wherein the tube includes a sample inlet, and isokinetic flow is achieved via a pump that controls the flow of the sample ballast water through the tube inlet by comparing a flow of the ballast water pipe with a flow of the sample ballast water through the tube; and controlling the flow of water through the sample tube inlet when a flow of the ballast water pipe is sensed to be different; withdrawing a portion of the sample ballast water for testing; and returning remaining sample ballast water to the ballast water pipe.

Abstract: An audio source system may be built into a garment to provide wiring from an audio source to earplugs. The wiring is brought from a point of connection to the audio source such as at a pocket and is then brought to the garment opening by tubes such as may be sewn with normal seams in construction of the garment such as side seams, sleeves seams and shoulder seams, and then into a channel at the opening, which may be a simple neck opening or a collared opening or a hood (in which the channel extends around the hood opening). An auxiliary wiring may be connected to allow a second hearing device such as ear buds or earphones. Wiring may be equipped with spring biased coils to allow stretching.

Abstract: An audio source system may be built into a garment such as a hooded garment in such a way that safety concerns such as with a hooded garment for children are taken into account so that the audio system wiring cannot be made loose causing a danger of strangulation nor can the hood be cinched. This is done by putting speakers into the hood between a lining and an outer layer and passing the wires into the space between them and then into a tube that is open to the hood inner space and down the tube to a pocket in the body of the garment. Also securing tabs are used to prevent cinching action upon pulling the wire.

Abstract: Described are pelvic implants (e.g., urinary incontinence sling, hammock, etc.) that provide treatment for pelvic floor disorders such as incontinence, stress urinary incontinence, prolapse (e.g., cystocele, enterocele, rectocele, vault prolapse), fecal incontinence, and the like, wherein the implant involves the ability to adjust dimensions of an implant before, during, or after implantation. In a preferred embodiment the implant (680) comprises a support portion piece (682) and an extension portion piece (688, 690) adjustably connected to the support portion piece through a frictional adjusting element (696) comprising an aperture through which a segment of extension portion extends.

Abstract: An audio source device may be used with a garment such as a hooded garment by passing the audio wires into a channel in the hood and having them exit the hood inside hollow lanyards with earbuds at the ends. A means to fix the wires and the lanyards to each other inside the hood is shown; and a means is shown to prevent lateral movement inside the hood. The wires and lanyard are crimped at the earbuds to prevent relative movement, the wires also being slacked inside the lanyard. The wire inside one or both of the lanyards can have an activatible microphone and the a source device can be a Bluetooth equipped device.
