摘要:
The present invention is a method of forming a fiber reinforced thermoset composite boom section or pipeline. The method comprises first creating a form and coating the form with a wax layer. A plurality of fiber reinforced thermoset composite material layers is then formed over the form. After the thermoset composite material layers cure, the form is removed.
摘要:
A boom section includes a first, a second, a third, and a fourth fiber reinforced thermoset composite material layer and a flex core layer. The first fiber reinforced thermoset composite material layer has glass fibers in a vinyl ester matrix. The second fiber reinforced thermoset composite material layer is disposed over the first composite material layer and has carbon fibers in an epoxy matrix. The flex core layer is disposed over the second composite material layer. The third fiber reinforced thermoset composite material layer is disposed over the flex core layer and has aramid fibers in a vinyl ester matrix. The fourth fiber reinforced thermoset composite material layer is disposed over the third composite material layer and has glass fibers in a vinyl ester matrix.
摘要:
The present invention is a boom system comprising a first boom section having a distal end and a proximal end. A second boom section includes a distal end and a proximal end, wherein the proximal end of the second boom section is rotatably coupled to the distal end of the first boom section. At least one of the boom sections is substantially formed from composite materials.

A directional headlamp assembly for independently directing light from a pair of headlamps includes a pair of headlamp modules and a controller. Each headlamp module replaces a respective headlamp of a pair of existing headlamps of a vehicle. The headlamp module comprises a first housing, which insertable of into an opening created upon removal of the respective headlamp, so that the first housing is engaged to the vehicle. A bulb is pivotally engaged to a front of the first housing. An actuator is engaged to and positioned in the first housing. The actuator is operationally engaged to the bulb. The controller is mountable within a passenger compartment of the vehicle so that it is accessible to a driver of the vehicle. The controller is independently and operationally engaged to each of the actuators and thus is positioned to selectively actuate each actuator to direct light emitted by an associated bulb.
摘要:
The present invention relates to composite material structures having reduced signal attenuation properties. In particular, the invention relates to composite drillstring components with electromagnetic properties and acoustic properties that enable the use of electromagnetic, acoustic and nuclear sensing equipment to obtain data from a wellbore from within a drill pipe. In a specific embodiment, a composite tube is incorporated with end-fittings which enable its incorporation into a drillstring thereby permitting the use of logging equipment from within the composite tube.

The invention provides compositions for increasing the clearance of protein aggregates, and pharmaceutical compositions comprising them, and methods for making and using them, including methods for accelerating protein aggregate clearance in the CNS, e.g., for treating diseases that are characterized by protein aggregation—including some degenerative neurological diseases such as Parkinson's disease. In one aspect, the compositions of the invention specifically target synuclein, beta-amyloid and/or tau protein aggregates, and the methods of the invention can be used to specifically prevent, reverse, slow or inhibit synuclein, beta-amyloid and/or tau protein aggregation. In alternative embodiments, the compositions and methods of the invention, are used to treat, prevent, reverse (partially or completely) or ameliorate (including slowing the progression of) degenerative neurological diseases related to or caused by protein aggregation, e.g., synuclein, beta-amyloid and/or tau protein aggregation. In one aspect, compositions and methods of this invention are used to treat, prevent or ameliorate (including slowing the progression of) Parkinson's disease, fronto-temporal dementia (FTD), Alzheimer's Disease (AD), Lewy body disease (LBD) and Multiple system atrophy (MSA).
摘要:
The disclosure is related to searching for a second device to provide a service that a first device is attempting to establish. The first device sends a search profile and a capabilities profile to the second device using near field communication (NFC), the search profile including criteria describing the service the first device is attempting to establish, the capabilities profile including connection capabilities of the first device, receives a score from the second device, the score indicating a closeness of a match between the search profile and the capabilities profile and one or more services and capabilities of the second device, and determines whether to connect with the second device to establish the service based on the received score.
