Abstract: Disclosed herein are embodiments of a method performed by a hearing aid and a hearing aid. An acoustical model can be used to generate first values (hk) for the multiple frequency channels based on first parameters (G, A, l); and a statistical model can be configured to generate second values (rk) for the multiple frequency channels based on values of second parameters (s1, s2, . . . , sn) and a set of basis vectors (u1, u2, . . . , un). An optimizer can be configured to obtain an optimized set of parameter values, wherein the optimized set of parameter values can be obtained by minimizing a difference between the first sound pressure levels (robs) and a combination of the first values (rk) and the second values (hk).

Abstract: A hearing aid configured for handsfree control. The hearing aid comprising one or more microphones configured to receive an input signal from the surroundings and a signal processor configured to process the input signal from the surroundings and a receiver configured to emit at least a part of said processed input signal into an ear of a hearing aid user, wherein the signal processor is further configured to process a gestural signal from a user of the hearing aid and make a control change to the hearing aid based on the gestural signal.

Abstract: A high density, generally recognized as safe, hybrid rocket motor is described, having a density-specific impulse similar to a solid rocket motor, with good performance approaching or equal to a liquid rocket motor. These high density hybrid motors resolve the packaging efficiency/effectiveness problems limiting the application of safe, low cost hybrid motor technology.

Abstract: Systems comprising a combination of the handheld imaging system with a nanoparticle multimodal contrast agent are disclosed. The imaging system exploits the advantages of both near-infrared emission and the photoacoustic effect by employing calcium phosphosilicate nanocolloid that encapsulates NIR and CT/MRI contrast agents for enhanced deep tissue imaging as well as a portable NIR/PA system using a tunable pulsed laser, CCD imaging technology and acoustic transducer arrays. Methods for using the system, for example in rapid diagnosis of trauma such as that inflicted on a battlefield, are provided.

Abstract: The invention relates to a device for in vivo sampling of biological species, comprising: a tubular sheath extending between a proximal end of said sheath and a distal end of said sheath, said distal end of the sheath having a projecting part, a rod extending between a proximal end of said rod and a distal end of said rod, capable of sliding in the sheath between a retracted position in which the distal end of the rod is located inside the sheath and a deployed position in which the distal end of the rod extends beyond the distal end of the sheath, said rod comprising a capturing support for capturing said biological species, made from a porous material, arranged in a distal region of the rod on a portion of the circumference of the rod such that the capturing support is located outside the sheath when the rod is in the deployed position of same.

Abstract: A universal capacitive power factor corrector usable with single phase inductive loads encases one capacitor, of 10 microfarads, one 240 volt varistor, one 22 microhenry coil, and a 330 k ohm resistor within a housing having a power cord, on off switch, 4 amp fuse, and a indicator lamp.

Abstract: A bi-propellant rocket motor having controlled thermal management is disclosed. The rocket motor produces thrust using a solid or gel-phase primary propellant that can be either fuel- or oxidizer-rich, with a complementary self-pressurizing secondary propellant selected to balance the primary propellant in terms of the equivalence ratio. The motor houses multiple propellant grains arranged in such a configuration that each chamber containing a primary grain serves as both propellant storage and the main combustion chamber for that propellant grain as it burns with the secondary propellant. The secondary propellant is stored separately, and the flow routed past the primary propellant chamber to provide cooling for adjacent primary propellant chambers limiting the temperature rise in the motor structure.
