Abstract: An electric vehicle can include an electric drive capable of moving the vehicles, together with a non-battery operative feature to enhance the performance of the vehicle, such as extending the range or increasing the power. The non-electrical enhanced feature is independent and not integrated with the electric drive, to enable the return of the vehicle design to pure electrical power with minimum modification.

Abstract: A print head comprising two shafts disposed in opposite sides of a filament to drive the filament to a heated chamber for delivering a molten material. The shafts are actively driven, for example, by two independent motors. The two shaft configuration of the print head can improve a control of the filament movement rate, especially for soft filament materials.

Abstract: Molds including 3D printed components can be used to cast objects. A model of the object can be separated into multiple components, with each component not having non-printable overhang structures, thus allowing the components to be directly printed without support structures. Shell models and shell molds, e.g., molds with hollow interior, can be used for cost effectiveness. The surface of the printed object can be smoothened, for example, by solvent vapor (such as acetone for plastic), by sanding, or by a smooth coating. The object can be combinatorially cast.

Abstract: Methods to form cross-linked or sintered objects include forming walls for reservoir layers, with cross-linkable or sinterable materials deposited in the reservoir layers. The cross-linkable or sinterable materials can then be cross-linked, e.g., changing the structure of the deposited cross linkable materials, or sintered, e.g., heat treated to fused the sinterable materials together. The walls for the reservoir layers can be removed after the objects are formed.

Abstract: The coupling between the plunger and the piston can be removable. The removal of the plunger can form a split syringe, which can be used for ease of transport. The split syringe can be mounted on a print head for printing using a 3D printer.

Abstract: A hybrid deposition process of CVD and ALD, called NanoLayer Deposition (NLD) is provided. The NLD process is a cyclic sequential deposition process, comprising introducing a first plurality of precursors to deposit a thin layer with the deposition process not self limiting, followed by introducing a second plurality of precursors for plasma treating the thin deposited layer. The plasma can be isotropic, anisotropic, or a combination of isotropic and anisotropic to optimize the effectiveness of the treatment of the thin deposited layers.

Abstract: A radial cam engine with an optimized cam configuration can provide improve performance over crankshaft internal combustion engines. The cam configuration can include a flat-top or flat bottom piston motion, multiple lobe cam configurations, matching piston force with torque/force ratio in combustion phase, asymmetry piston motions for improved power transfer during combustion phase, and/or offset piston and cam configurations. The radial cam engine can be used in vehicles, such as hybrid vehicles.

Abstract: A hybrid deposition process of CVD and ALD, called NanoLayer Deposition (NLD) is provided. The NLD process is a cyclic sequential deposition process, including introducing a first plurality of precursors to deposit a thin film and introducing a second plurality of precursors to modify the deposited thin film. The deposition using the first set of precursors is not self limiting and is a function of substrate temperature and process time. The second set of precursors modifies the already deposited film characteristics. The second set of precursors can treat the deposited film, including treatments such as modification of film composition and doping or removal of impurities from the deposited film. The second set of precursors can also deposit another layer on the deposited film. The additional layer can react with the existing layer to form a compound layer, or can have minimum reaction to form a nanolaminate film.
