Abstract: A method and system provide the ability to deliver media content. A packager receives an original encrypted transport stream, and segments the stream into multiple fixed-duration transport stream files (chunks). The packager further generates a manifest file that describes the chunks and is consistent with a hypertext transfer protocol (HTTP) live streaming (HLS) protocol. The manifest file and chunks are delivered to a content delivery network (CDN). An enhanced HLS client is embed in an integrated receiver decoder (IRD). The enhanced HLS client retrieves the manifest file and the chunks from the CDN, and reconstructs the original encrypted transport stream for use by a service provider network.

Abstract: An example system includes two objects each having a known dimension and positioned spaced apart by a known distance, and a fixture having an opening for receiving an imaging device and for holding the two objects in a field of view of the imaging device such that the field of view of the imaging device originates from a point normal to a surface of the base. The fixture holds the imaging device at a fixed distance from an object being imaged and controls an amount of incident light on the imaging device. An example method of determining image scaling includes holding an imaging device at a fixed distance from an object being imaged, and positioning the two objects in the field of view of the imaging device such that the field of view of the imaging device originates from a point normal to a line formed by the known distance.

Abstract: An example system includes a base, two objects each having a known dimension and positioned on the base spaced apart by a known distance, an imaging device positioned such that the two objects are in a field of view of the imaging device and such that the field of view of the imaging device originates from a point normal to a surface of the base, and a computing device having one or more processors and non-transitory computer readable medium storing instructions executable by the one or more processors to perform functions. The functions include receiving an image from the imaging device capturing the two objects in the field of view, and based on one or more of the known dimension of the two objects and the known distance between the two objects, determining an image scaling factor that associates a number of pixels in the image to a physical distance.

Abstract: An electric field plasma pump includes a toroidal ring bias electrode (56) positioned near the divertor strike point of a poloidal divertor of a tokamak (20), or similar plasma-confining apparatus. For optimum plasma pumping, the separatrix (40) of the poloidal divertor contacts the ring electrode (56), which then also acts as a divertor plate. A plenum (54) or other duct near the electrode (56) includes an entrance aperture open to receive electrically-driven plasma. The electrode (56) is insulated laterally with insulators (63,64), one of which (64) is positioned opposite the electrode at the entrance aperture. An electric field E is established between the ring electrode (56) and a vacuum vessel wall (22), with the polarity of the bias applied to the electrode being relative to the vessel wall selected such that the resultant electric field E interacts with the magnetic field B already existing in the tokamak to create an E.times.B/B.sup.2 drift velocity that drives plasma into the entrance aperture.

Laser head 24 is operable for providing an output chirped laser beam 32 and for receiving a reflected output beam 34. A corner cube reflector 36 is mounted by an arm 38 to a headstock spindle 18. The reflected return beam is detected and processed by a phase demodulator and converted into pulses. The pulses are counted and converted to distance and displayed.

Abstract: A probe assembly has a housing connected to the head of a coordinate measuring machine, a carrier movably connected to the housing, and a piezoelectric crystal mounted on the carrier. A stylus is mounted on the carrier. An electronic circuit receives signals from the crystal and, at an adjustable threshold value, the circuit provides output signals which are greater than and substantially simultaneous with signals from the crystal. A timer maintains the output signal for a time interval after the signal is produced by the crystal.

Abstract: A tokamak apparatus includes an electrically conductive metal pressure vessel for defining a chamber and confining liquid therein. A liner disposed within said chamber defines a toroidal space within the liner and confines gas therein. The metal vessel provides an electrically conductive path linking the toroidal space. Liquid metal is forced outwardly through the chamber outside of the toroidal space to generate electric current in the conductive path and thereby generate a toroidal magnetic field within the toroidal space. Toroidal plasma is developed within the toroidal space about the major axis thereof.
