Abstract: A powertrain system for a commercial electric vehicle includes an electric motor, a multi-speed transmission, and a drive line. A reducer assembly is added prior to connection to the drive line to decease the rotational speed generated by the electric motor prior to being transmitted to the drive line. The reducer assembly can be placed before the multi-speed transmission input, after the multi-speed transmission output, or somewhere in between those two locations. The reducer assembly includes a reducer gearset for decreasing shaft rotational speed. The reducer assembly may include adjacent idler gears to reduce the pressure load on the gear teeth of the reducer assembly.

Abstract: Disclosed herein is an air cooler including a housing having an upper portion and a lower portion. The upper portion of the housing includes an air intake, an air output, and a manually operated fan. The lower portion of the housing includes an air passage leading from the air intake to the air output. The air passage may include baffles that cause air to travel laterally. The air cooler is particularly designed for use on a playground.

Abstract: A device to determine density includes a housing, a first transducer disposed in the housing at a first position, and a second transducer disposed in the housing at a second position. The second transducer is located a distance from the first transducer. The device also includes a controller that reads a first output from the first transducer, and reads a second output from the second transducer. The controller determines a density of a liquid based on the first output, the second output, and the distance.

Abstract: An automated resonant waveguide cavity system for determining one or complex permittivity measurements of a sample is provided. The automated resonant waveguide cavity system includes a resonant cavity, a waveguide coupled to the resonant cavity, a programmable network analyzer (PNA) coupled to the waveguide, and a computing device. The computing device includes a memory storing processor executable code for a determination engine and a processor executing the processor executable code to cause the determination engine to obtain data from the PNA. The data is respective to the sample within the resonant cavity. The determination engine further integrates a plurality of analytical and modeling functions in determining the complex permittivity values of the sample from the data.

Abstract: Examples are directed toward systems and methods relating to collecting and analyzing samples. For example, a system includes a cold trap that directly collects a sample. The cold trap operates to serve as a collection filter while the system draws in a flow across the cold trap. A thermal heater, coupled to the cold trap, flash heats the cold trap to produce a released sample from the cold trap at a release concentration. An analyzer entrains the released sample at the release concentration into a sampling flow of the analyzer for analysis.

Abstract: The present invention pertains to a resonant cavity system, more specifically, a resonant system for measuring the dielectric constant of a sample and its method of use. The system and method provide for holding sample materials, which can be in solid, liquid, or powder form, and for reducing the size of the requisite cavity for measurement. The construction incorporates waveguide flange connectors to seal the electromagnetic cavity, which facilitates the measurement of low-loss materials. The design for signal input enables the use of standard calibration techniques and measurement.

Abstract: This disclosed console is for mounting within a vehicle. The console includes a base configured to be coupled to the vehicle and a storage enclosure coupled to the base. The storage enclosure is movable between a first position and a second position relative to the base such that a first occupant is provided access to the storage enclosure. The storage enclosure is movable between a stowed position and a deployed position. The deployed position is configured to provide access to a second occupant.

Abstract: The invention provides a controlled hypergolic approach to using concentrated hydrogen peroxide in combination with certain hydrocarbons such as ethanol, methanol, methane as well as more common fuels such as gasoline, diesel, DME, JP5, JP8 and the like to generate a gas mixture primarily composed of hydrogen and carbon dioxide. Because air is not used as the oxygen source, this novel process does not allow the formation of nitrous oxide (NOx) compounds, thereby avoiding the primary source of nitrogen contamination as well. The process is executed in a constraining system on a micro scale such that the resulting hydrogen supply is self-pressurizing. This enables the incorporation of an “on-demand” hydrogen fuel source for a variable output fuel cell power plant such as those proposed for use in automobiles, marine vessels and stationary power sources. In another embodiment of the present invention hydrogen peroxide is catalytically, or thermally reacted to provide H2O vapor and O2.

Abstract: A first-in-first-out (“FIFO”) buffer is provided for buffering communication data. The FIFO buffer includes a write port having a data input, an end-of-frame input and a write control input, a read port having a data output, an end-of-frame output and a read control input, and a plurality of storage locations. A write end-of-frame counter is coupled to the write port and has a write count output, which increments as a function of the end-of-frame input and the write control input. A read end-of-frame counter is coupled to the read port and has a read count output, which increments as a function of the end-of-frame output and the read control input. A comparator has a first compare input coupled to the write count output, a second compare input coupled to the read count output and a compare output indicating whether there is a data frame stored in the plurality of storage locations.

Abstract: A positive displacement apparatus of the general type used as superchargers on internal combustion engines has two or more compression chambers capable of lateral movement to accommodate circular motion of the pistons. The driving forces for the chambers are derived from forces originating independently of the movement of the pistons, that is, the chambers, instead of being driven by the pistons, are driven directly from the eccentric mechanism that drives the pistons. A lateral reciprocating motion is imparted to two transfer members that are mechanically secured to the end of, or form part of, the chamber. Preferably, each of the end plates of the chamber forms an integral part of the chamber drive structure. An orbitally-driven, non-rotating, rigid drive sleeve encompasses two spaced eccentric drive members on a drive shaft and supports the piston drive structures. Rotational forces generated by the chamber drive arrangement are resisted by sets of guides rails and slidably mounted pads.
