摘要:
A system and method of micro dosing containers on a conveying system is disclosed. The system includes a mixing tank to maintain suspended solids in a mixture; a dosing assembly to inject micro-doses of the mixture into bottles; a recirculation assembly to circulate the mixture from the supply tank to the dosing assembly and back to the supply tank; a power and controls operation assembly to supply the system with power, to provide the system with electromechanical control and/or to provide a user interface; and a stand to hold at least the supply tank, the portable dosing assembly, the recirculation assembly and/or the power and/or controls operation assembly.

In one aspect, the present disclosure relates to a device including a substrate, having a top surface and a bottom surface; an array of nanowires having a base and a top surface, the base contacting the top surface of the substrate; a contacting structure having a non-nanostructured surface, having a top surface and a bottom surface, located on the same side of the substrate as the array of silicon nanowires; and an electrical contact in contact with the top surface of the contacting structure. In some embodiments, the device includes an aluminum oxide passivation layer over the array of nanowires. In some embodiments, the layer of aluminum oxide is deposited via atomic layer deposition.

A secure media device preferably includes a Universal Serial Bus (USB) Mass Storage Class (MSC) interface and a USB Human Interface Device (HID) interface. A storage media area is also preferably provided. The storage media is preferably divided into a secure and nonsecure area by arranging the storage media into multiple Logical Units (LUNs). The nonsecure area is preferably accessed in a conventional manner using a host USB MSC driver through the USB MSC interface on the storage device. A password dialog application can be located in the nonsecure area of the storage device.

An efficient oil based drilling fluid is provided that includes a polymer additive effective at imparting suspension characteristics without the presence of organophilic clays, while also providing filtration control. The fluid is shear thinning and has good fluid rheology over a broad temperature range. A preferred polymer for the additive is substantially linear and comprises mostly hydrophobic monomers and some hydrophilic monomers such as, for example, an emulsion copolymer of 2-ethylhexyl acrylate and acrylic acid.

Lifts for cargo carrying vehicles (e.g. trucks) and methods of lifting objects associated with such vehicles. The lift may include a deployment mechanism, a lift mechanism, and a lift deck. The deployment mechanism couples to the frame of the vehicle and deploys the lift mechanism to a position adjacent to the vehicle where the lift mechanism lifts the lift deck to a position that is substantially above the a cargo support surface of the vehicle. Preferably, the lift mechanism includes a pneumatic actuator sized to extend the lift mechanism about 84.″ A housing may also be provided on the vehicle for the lift. In one embodiment, the deployment mechanism is a slide mechanism and the lift mechanism is a scissor mechanism. A support bracket may be included to support the deployed lift mechanism. Additionally, a handrail may be provided on the lift deck.

An electronic circuit for generating a trapezoidal excitation waveform includes a controllable frequency source and a trapezoidal waveform generator. The controllable frequency source generates a source waveform that, upon energization thereof, has an initial frequency value, and decreases in frequency to a substantially constant frequency value a time period after energization. The trapezoidal waveform generator receives the source waveform and, in response, generates a trapezoidal waveform at least when the source waveform frequency attains the substantially constant frequency value.
