A lift-type turbine comprising at least three blades at circumferentially spaced positions is supported for rotation about a vertical axis. Each blade has an airfoil shape to generate a torque about the axis responsive to wind across the blades. A support comprising cables under tension is connected between adjacent ones of the blades to extend generally circumferentially about the turbine. Accordingly a minimum number of parts form the structure of the blades while minimizing the drag produced during rotation thereof due to the support members lying in a common circumferential path. The tension of the support members can support the blades in a pre-stressed condition to optimize the shape and performance thereof.

In a passive optical network (PON), a burst-mode receiver of an optical line terminator (OLT) is initialized during an initialization phase, such as ranging, by asserting one or more reset signals in response to detecting the presence of a packet signal. For example, after the OLT transmits an initialization message, such as a ranging grant, to an optical network unit (ONU), it asserts one or more reset signals when it detects the presence of a packet signal received from the ONU in response.

A system of counter-rotating propellers for an aircraft turbine engine including a first and a second propeller, each including a stalling control system for the blades, a rotating actuating mechanism for sliding an element to move the angle of attack of the blades, and a disengaging mechanism for rigidly fixing in rotation the rotating actuating mechanism. The system is designed so that when the disengaging mechanism is engaged, a relative rotation speed is created between the elements and the associated rotating actuating mechanism thereof, bringing the blades into a neutral position thereof for feathering.

An optical apparatus minimizes autofluorescence and stray light as well as leakage of excitation light and efficiently utilizes illuminating light from a fluorescence illumination optical system to allow observation of a bright fluorescence image. An observation apparatus has an objective, an observation optical system unit including a variable magnification optical system, and an imaging optical system unit including an imaging lens and an eyepiece. A fluorescence illumination apparatus, which is provided separately, is removably attached to the observation apparatus. The fluorescence illumination apparatus has a light source, a collector lens unit, and a reflecting member placed between the objective and the observation optical system unit at a position displaced from the optical axis of the objective to make light from the light source incident on the objective. An excitation filter is provided between the light source and the reflecting member. An optical member for selectively transmitting fluorescent light emitted from a sample is placed between the objective and the observation optical system unit.

A signal processing system, such as a hearing aid system, adapted to enhance binaural input signals is provided. The signal processing system is essentially a system with a first signal channel having a first filter and a second signal channel having a second filter for processing first and second channel inputs and producing first and second channel outputs, respectively. Filter coefficients of at least one of the first and second filters are adjusted to minimize the difference between the first channel input and the second channel input in producing the first and second channel outputs. The resultant signal match processing of the signal processing system gives broader regions of signal suppression than using the Wiener filters alone for frequency regions where the interaural correlation is low, and may be more effective in reducing the effects of interference on the desired speech signal. Modifications to the algorithms can be made to accommodate sound sources located to the sides as well as the front of the listener. Processing artifacts can be reduced by using longer averaging time constants for estimating the signal power and cross-spectra as the signal-to-noise ratio decreases. A stability constant can also be incorporated in the transfer functions of the first and second filters to increase the stability of the signal processing system.

A jounce bumper is used in a suspension system of a vehicle. The jounce bumper comprises an outer member comprising a base portion and a sidewall extending from said base portion. The sidewall of the outer member is flexible relative to the base portion. The base portion and the sidewall define a cavity such that the outer member has a cup-shaped configuration. A bumper is at least partially seated within the cavity of the outer member. The bumper is compressible into the cavity of the outer member such that the bumper expands against the sidewall of the outer member, which forces the sidewall of the outer member to flex and expand radially outward. An isolation layer is disposed on the base of the outer member outside of the cavity and separates the outer member from either the strut assembly or the frame member.

A vertical axis turbine includes a modified darrieus type rotor having at least three circumferentially spaced apart blades, each having an airfoil shape in cross section such that the blades generate a torque in a direction of rotation of the turbine about the vertical axis responsive to a generally horizontal wind across the blades. Support members, for example flexible cables, are connected under tension between adjacent ones of the blades to extend in a generally circumferential direction about the turbine at an inclination from horizontal in a criss-crossing pattern with other support members. A tensioning mechanism also urges opposing top and bottom ends of the rotor towards one another such that the blades are supported under compression in a pre-stressed condition by the support members and the tensioning mechanism to maintain the blades in a substantially rigid and fixed orientation throughout the operation of the turbine rotor.

A lubrication system for transporting lubrication oil in an automatic transmission includes a radial lubrication passage opening at a hole in an outer peripheral surface of a shaft. The hole has a cross section that is elongated only along a first axis offset from a central axis the shaft so as to follow angular deformation caused by unidirectional torque applied to the shaft whereby stress produced around the hole by torque transmitted through the rotating shaft is reduced, thus minimizing fatigue and increasing a useful life of the automatic planetary transmission. Preferably cross sections of the radial passage taken sequentially along the transverse axis are elongated near outer peripheral surface of the shaft but become circular towards the central axis. With this arrangement stress produced around the hole by torque transmitted through the rotating shaft is reduced thus reducing fatigue and increasing a useful life of the transmission.

An aesthetically pleasing trailer incorporates stock motorcycle side bags into the trailer, surrounding a central cargo box. The central compartment is designed in a generally parallelepiped shape, and has a leading surface which leads the side bags through an airstream when said trailer is traveling forward. The central cargo box may include a cover resembling a motorcycle seat, and will preferably have a locking closure for securing the cargo area. Most preferably, release mechanisms under the cover open access to the side bags. Consequently, access to the side bags is controlled through a single closure lock. The trailer may also be supported upon a torsion axle.
