| 20120145465 | DRILL BIT - The proposed device relates to roller drill bits with air drilling capability and can be used for drilling of rocks of high hardness. The drill bit includes a body and rock-destroying elements with cutting equipment mounted on the body one inside the other by means of bearing supports, wherein the inner element is located at an angle relatively to the axis of the drill bit, and the outer element is located in the opposite direction of the axis. The device provides for an increase of the service life, high efficiency, and interchangeability due to a special design, which envisages the cutting equipment formed as replaceable jet nozzles made of hardwearing material and provided with arm insertions, preferably made of wolframite-cobalt based alloy, wherein the bearing support of each rock-destroying element is furnished with a unit adjusting the axial play value of the rock-destroying elements. | 06-14-2012 |

| 20090277486 | AUTOMATIC RETRACTABLE CANOPY FOR WHEELCHAIRS, SCOOTERS, AND THE LIKE - A folding canopy for a mobility device, such as a wheelchair or scooter, can be displaced, via switch activation, from a folded position behind the backrest to the operating position above the mobility device. In the folded position, the canopy and structural members are kept behind the backrest. A press of the switch located on the armrest activates an electric motor and drives a mechanical assembly comprising of: two gears a shaft and two U-shape tubular structural members attached to weather resistant upholstery. The canopy and structural members assemble directly above the vehicle. Another press of the switch retracts the canopy. | 11-12-2009 |

| 20090133505 | Shear stress measurement apparatus - A shear stress sensor for measuring the shear force of a fluid flowing along a wall. A floating member, flush with the wall, senses a shear force of the flowing fluid. The floating member is mounted by support means to a base element that is placed in the wall, so that the floating member is flush with the wall and a shear force, sensed by the floating member, is translated via the support means to a micro-resonator. The force acting on the micro-resonator changes the shape and the refractive index of the micro-resonator, thereby changing the resonant frequency of the micro-resonator and causing a shift in the spectrum of wavelengths of light that is introduced to the micro-resonator. This shift in the spectrum of wavelengths is representative of the shear force of the flowing fluid. | 05-28-2009 |
| 20090282928 | Load Cell And System For Measuring Forces Based on Optical Spectra Shifts - A load cell having an optical micro-resonator in a housing formed of high thermally conductive material. Upon application of a force to a surface of the housing, the micro-resonator is squeezed and changes in shape and refractive index, thereby changing the resonant frequency of the micro-resonator and causing a shift in the spectrum of wavelengths of light that is introduced to the micro-resonator. This shift in the spectrum of wavelengths is representative of the force applied to the housing of the load cell. | 11-19-2009 |
| 20100326200 | Shear Stress Measurement Apparatus - A shear stress sensor for measuring the shear force of a fluid flowing along a wall. A floating member, flush with the wall, senses a shear force of the flowing fluid. The floating member is mounted by support means to a base element that is placed in the wall, so that the floating member is flush with the wall and a shear force, sensed by the floating member, is translated via the support means to a Fiber Bragg Grating. The force acting on the Fiber Bragg Grating changes the shape and the refractive index of the Fiber Bragg Grating, thereby changing the resonant frequency of the Fiber Bragg Grating and causing a shift in the spectrum of wavelengths of light that is introduced to the Fiber Bragg Grating. This shift in the spectrum of wavelengths is representative of the shear force of the flowing fluid. | 12-30-2010 |
