A first acoustic driver is disposed in the first mounting recess. At least a first sound bore is formed in the solid earphone body. The at least a first sound bore fluidly communicates with the first mounting recess and a first exit port formed at a second end of the earphone body. The second end of the earphone body is configured to be placed in an ear canal of a user. The earphone can be fabricated by a method that includes defining negative spaces for the first acoustic driver and the at least a first sound bore in a virtual model of the earphone body.

Abstract: Innovations for an improved earphone design are provided. The earphone includes an earphone body with three or more acoustic drivers disposed substantially congruently about an axis. One or more acoustic drivers included in the earphone body include a first, sound emitting, end and a second opposing end. A vent is defined in a compartment in which the acoustic driver is received and is coaxial to an axis passing through the first and second ends of the acoustic driver.

Abstract: A passively cooled pipe made of a material with a high coefficient of thermal conductivity that has a lockable, invertable, combustion bowl/storage compartment. The pipe is designed for the combustion of dry organic matter. It has a series of passive radiator fins about the outer faces of its sides for the dissipation of heat there along its body, and an aggressive smoke mixing design in the bore of the shank section that aids in the removal of tar and smoke particles. The inside volume of the shank also has a series of passive radiator fins in operational contact with the sides of the shank. There is a removable locking tool housed in the passive radiator fins on one of the outer faces, used to lock the combustion bowl in either of its positions. The locking tool also disassembles the two halves of the pipe for cleaning.

Abstract: An improved in-ear monitor that incorporates high frequency balanced armature driver tuning, both low frequency dynamic driver and balanced armature driver tuning, mid range and high range frequency balanced armature driver tuning. It also utilizes a stacked metalized plastic film chip capacitor style of crossover component to filter the mid and low frequency signals from the high frequency driver/s for enhanced clarity and to impart a wider image to the fidelity sound. I has a spout that has a series of stanchions or stanchions and resonator box cavities for the simplified connection and disconnection of sound tubes and resonator boxes.

Abstract: A control system for an exhaust brake which operates to impede exhaust flow from a turbocharged combustion engine when the engine throttle is closed. The control system includes means for delaying application the exhaust brake only when the vehicle throttle is closed to allow the rotational speed of the turbo charger to drop thereby reducing wear to seal components.

Abstract: The invention provides a system and method for turbulent flow drag reduction using discrete counter-rotating elements disposed adjacent a bounding surface and arranged to effectively disrupt or suppress stream-wise vortices and/or traveling waves thereby reducing turbulence and increasing fluid flow. In embodiments, the counter-rotating elements effectively decouple the interaction between traveling waves and stream-wise vortices. By using discrete counter-rotating elements as disclosed, the energy input to the counter-rotating elements is advantageously less than the energy gained from the flow rate increase. The counter-rotating elements may comprise e.g., counter-rotating strips, counter-rotating disks or a plurality of sequentially activated jets. In addition, the bounding surface may comprise a section or pipe, a substantially planar surface, etc. The counter-rotating elements may be used along a section of a pipe, on a surface of an aircraft wing, in HVAC systems, etc.

Abstract: The present invention provides a system, method and product for porting computationally complex CFD calculations to a coprocessor in order to decrease overall processing time. The system comprises a CPU in communication with a coprocessor over a high speed interconnect. In addition, an optional display may be provided for displaying the calculated flow field. The system and method include porting variables of governing equations from a CPU to a coprocessor; receiving calculated source terms from the coprocessor; and solving the governing equations at the CPU using the calculated source terms. In a further aspect, the CPU compresses the governing equations into combination of higher and/or lower order equations with fewer variables for porting to the coprocessor. The coprocessor receives the variables, iteratively solves for source terms of the equations using a plurality of parallel pipelines, and transfers the results to the CPU.
