In method of injecting a substance into a living cell having a cell membrane, the substance, the cell and a liquid are placed into a tapering passage. Energy is applied to the cell, thereby inducing poration. To sort cells, a cellular suspension is placed in a tapering passage, including a narrow end that defines an opening that has a dimension corresponding to a cell size. An acoustic wave is applied, thereby forcing cells having a cell size smaller than the selected cell size through the opening, with a portion of the cells having a cell size not smaller than the selected cell size not forced through the opening. To extract material from a cell, an electric field and an acoustic wave are applied, thereby causing the cell membrane to allow the material to pass out of the cell.

A design structure embodied in a machine readable medium used in a design process includes a current mirror circuit that includes a reference current source that generates a reference current, a reference transistor, a mirror transistor and a ratioed body bias feedback unit. The reference transistor has a first node that is coupled to the output of the reference current source, a gate that is coupled to the first node and a second node coupled to a common voltage. The mirror transistor has a gate coupled to the first node. The ratioed body bias feedback unit generates a body bias voltage coupled to the body of the reference transistor and the body of the mirror transistor. The ratioed body bias feedback unit is configured to adjust the body bias voltage in relationship to the common voltage so that the reference transistor and the mirror transistor each have a threshold voltage within a predefined range.

A multiphase-liquid level sensing system for sensing a layer depth and thickness of a liquid of a first phase that floats on a liquid of a different second phase includes an elongated stem that defines an elongated cavity. A float, which exhibits a sensible property, is disposed coaxially around the elongated stem and has negative buoyancy relative to the liquid of the first phase and positive buoyancy relative to the liquid of the second phase. A level sensor senses the sensible property and indicates a second phase liquid distance from the float to the bottom of the stem. An overburden sensor extends downwardly from the stem senses total liquid thickness of the liquid above the overburden sensor. A computational circuit calculates a layer depth and thickness of the liquid of the first phase, based on input from the level sensor and the overburden sensor.

A vehicle includes a cabin defined by a front, a back, a roof, a floor, a first side, and a second side opposite the first side. The vehicle also includes a window having a surface area that covers at least 50% of the first side, and seating in the cabin arranged to face the first side. The seating may be arranged in at least two rows, with a first row of seats having a first elevation relative to the floor, and a second row of seats having a second elevation relative to the floor, where the second elevation being greater than the first elevation. The vehicle also includes a video system comprising a plurality of video monitors located at the first side. Other variations and a related method of providing entertainment using vehicles of the claimed type are also described herein.

In a method of making a functionalized graphitic structure, a portion of a multi-layered graphene surface extending from a silicon carbide substrate is exposed to an acidic environment so as to separate graphene layers in a portion of the multi-layered graphene surface. The portion of the multi-layered graphene surface is exposed to a functionalizing material that binds to carbon atoms in the graphene sheets so that the functionalizing material remains between the graphene sheets, thereby generating a functionalized graphitic structure. The functionalized graphitic structure is dried in an inert environment.

In a method for enabling a root device to access a plurality of memory locations in an address space in an endpoint device, a first access is sent to the endpoint device by transmitting a first header and a first address. The header includes a continue bit that is set at a first state that indicates that the first access is accessing a selected first memory location that the address is being sent. A first memory location is accessed when the continue bit is in the first state. A second access, which accesses accessing a second memory location that is contiguous to an immediately previously accessed memory location, is sent to the endpoint device by transmitting a header that includes a continue bit set to a second state and not sending an address. The second memory location corresponds to the first address plus a predetermined address offset.

A trim panel for an aircraft interior includes a first sound attenuating layer, a structural layer and a second sound attenuating layer. The structural layer is coupled to the exterior sound attenuating layer, and has an exterior side and an opposite interior side. The structural layer defines a plurality of passages that open to both the exterior side and the interior side so as to minimize radiation of noise due to a hydrodynamic shortcut created by each of the passages across the structural layer. The second sound attenuating layer is coupled to the structural layer and has a high sound absorption characteristic. The second sound attenuating layer is configured to be disposed adjacent to the aircraft interior.

A method of making nanostructures using a self-assembled monolayer of organic spheres is disclosed. The nanostructures include bowl-shaped structures and patterned elongated nanostructures. A bowl-shaped nanostructure with a nanorod grown from a conductive substrate through the bowl-shaped nanostructure may be configured as a field emitter or a vertical field effect transistor. A method of separating nanoparticles of a desired size employs an array of bowl-shaped structures.
