Abstract: A light-emitting device includes: a substrate, at least one induction coil located on a side of the substrate, and at least two light-emitting units. The induction coil includes turns of conductive wiring. The light-emitting units are located on a side of the induction coil away from the substrate; each light-emitting unit includes a first electrode and a second electrode, and a first electrode and a second electrode of a same light-emitting unit are electrically connected to different turns of conductive wiring of a same induction coil; the light-emitting units include at least one first-type light-emitting unit and at least one second-type light-emitting unit. An equivalent number of turns of conductive wiring between a first electrode and a second electrode of a first-type light-emitting unit is different from an equivalent number of turns of conductive wiring between a first electrode and a second electrode of a second-type light-emitting unit.

Abstract: The invention relates to methods for analyzing the miscibility of compositions. The methods may further quantify the degree of miscibility of the compositions.

Abstract: A disk holding device for packaging hard drive disks includes a base and a cover. The base includes a central portion and at least one locking surface near an end of the base. The cover includes a latch arm near one end of the cover. The latch arm has a locking tab that transversely protrudes from the latch arm in a direction from the central portion of the base toward the end of the base. A space extends between the cover and the base for receiving a cassette portion when the locking tab is received against the at least one locking surface.

Abstract: An inflated non-latex, portable balloon has an internal lamp or transducer connected to an external battery. The balloon is made from an open-necked balloon body formed from panels of balloon material having inner polyethylene layers heat sealed together along peripheries. A pair of flat, metal conductor leads are hermetically sealed in polyethylene to extend in parallel to provide a discrete integral elongate, strip form lead member which is located extending through the open neck with one end supportingly connecting the lamp within the body. The balloon body is inflated and the neck hermetically sealed with the lead member by heat/pressure or ultrasonics thereby fusing together polyethylene surfaces of the lead member and the balloon panels to provide a hermetic seal; and, a battery is connected to ends of the leads outside the balloon.
