The present invention relates to a laser device comprising at least one large area VCSEL (101) and at least one optical feedback element (201, 301) providing an angular-selective feedback for laser radiation emitted from the laser. The angular-selective feedback is higher for at least one portion of laser radiation emitted at angles θ>0 to the optical axis (601) of the laser than for laser radiation emitted on said optical axis (601). The invention also refers to a method of stabilizing a laser emission of a large area VCSEL in a desired angular distribution (501, 502). With the proposed device and method, the intensity distribution of a large area VCSEL can be stabilized in a desired shape, for example a ring shape.

A radio frequency receiver subject to a large in-band interferor employs active cancellation with coarse and fine cancellation signals, each with a respective radio frequency combiner, in order to increase the effective dynamic range of the receiver for weak signals of interest. One or both can be digitally synthesized. This is particularly applicable for co-site interference, whereby the interfering transmit signal is directly accessible. A similar system and method may also be applied to external interferors such as those produced by deliberate or unintentional jamming signals, or by strong multipath signals. An adaptive algorithm may be used for dynamic delay and gain matching. In a preferred embodiment, a hybrid technology hybrid temperature system incorporates both superconducting and semiconducting components to achieve enhanced broadband performance.

Methods are described for determining the state of charge and/or the operability of a charge accumulator using estimates. The information, which is obtained at a least two different operating points or operating conditions of the energy accumulator, is taken into account in the estimates. The estimates are carried out with regard to an instantaneous and/or future state of charge and/or an instantaneous and/or future operability of the charge accumulator. Different methods are executed, depending on the operating point or operating condition. The methods may be run in a processor of a control unit.

A pressure exchanger for transferring pressure from a higher pressure liquid in a first liquid system to a lower pressure liquid in a second liquid system having a housing (8) with inlet and outlet connection openings (10-10.3) for each liquid and a rotor (1) arranged in the housing for rotation about a longitudinal axis. The rotor has a plurality of through channels (13) arranged around the longitudinal axis with openings (12) on axial end faces (2, 3) of the rotor. The rotor channels (13) are connected to the connection openings (10-10.3) through flow openings (11-11.3) in the housing such that during rotation of the rotor high pressure liquid and low pressure liquid are alternately supplied to the respective systems. A predominantly axially extending flow transition is formed between the flow openings (11-11.3) in the housing and the openings (12) of the rotor channels (13), and the flow openings in the housing form part of curved cavities (19) with each cavity (19) simultaneously covering several rotor channel openings (12) and having a shape which equilibrates the liquid flow speed in the vicinity of the housing flow openings (11-11.3). External surfaces (5-5.3) of the rotor (1) have an energy converting or energy transmitting configuration (6), and a partial flow (TS) of high pressure and/or flow energy impinging on the configuration (6) produces rotation of the rotor (1). A regulator (7) the varies the amount of the partial flow (TS) and the rotational speed of the rotor (1) and controls the rotational speed of the rotor for substantially shock-free admission of the mass flow into the rotor channels (13).

A microengineered optical scanner based on a moving cantilevered dielectric waveguide is described. The waveguide is excited into resonant mechanical motion by a drive located at its root. Stress sensors detect the bending of the waveguide, allowing closed loop control of the motion. A moving image of the light emitted from the moving tip of the waveguide is created by a lens. The moving image acts as a scan line. Light back-scattered from a rough surface placed at the image plane is collected back into the waveguide by confocal imaging. The light collected in the cladding of the waveguide has higher numerical aperture than the light collected in the core. The cladding light is detected by a mode-stripping detector. Techniques for combining a cantilevered waveguide, a drive, motion sensors and a mode-stripping detector using microelectromechanical systems (MEMS) technology are described.

A system for cold gas dynamic spraying of particulate material has a de Laval nozzle and two or more radial particle inlets located between the throat and the outlet of the nozzle, the two or more particle inlets arranged symmetrically around a linear flow path of the nozzle. Blocking of the inlets is reduced by controlling pressure of particle carrier gas to provide a stable particulate material injection pressure before and during introduction of working gas into the nozzle, and/or by clearing the particle inlets of residual particles after a spraying process. Such a system and associated method combines benefits of both downstream and upstream cold gas spray systems. Further, a nozzle for spraying particulate material having a cross-sectional shape that is narrower in a middle section compared to edge sections provides coatings with superior cross-sectional profiles.

Components, subassemblies, systems, and/or methods for improving the performance and increasing the life of continuously variable transmissions (CVT). A first stator may be formed with an outer diameter greater than an outer diameter of a second stator. A stator may have radial slots formed to extend farther radially inward than slots on the other stator. The larger outer diameter of a stator or the formation of guide slots on a first stator extending farther radially inward of guide slots on a second stator may prevent egress of a planet axle from a radial slot, increase range of the CVT, allow for larger tolerances to reduce losses, and other advantages, Slots on a timing plate may be formed having a width greater than a width of guide slots formed on either stator to allow the stators to control adjustments while the timing plate avoids runaway axles. The shape, including junction between surfaces on a timing plate or stator may also prevent an axle from egressing. Any one or a combination of these features allow a CVT to be formed smaller and lighter to allow for clearance in smaller environments and for reduced inertia.
