Title: Method and apparatus for ink jet printing
Inventor: BADOVINAC MILAN
IPC: B41J2/01
Filed: 2002-03-28
Abstract: Ink jet printing is provided on large area substrates such as wide width textile webs. The printheads are driven by linear servo motors (633) across a bridge (630) that extends across the substrate. The timing of the jetting of the ink is coordinated with the motion of the printheads (640, 641), so that the heads can be rapidly moved and the ink can be jetted while the printhead s are accelerating or decelerating as they move on the bridge. Preferably, ultraviolet (UV) light curable ink is jetted and first partially cured with UV light (645, 646) and then subjected to heating to more completely reduce uncured monomers of the ink on the substrate. Preferably, the heat is applie d by contacting the substrate with a heated plate (661, 662). Ink jet printing is provided using ultraviolet (UV) light curable or other curable compositio n or stable or other printable substance. In certain embodiments the UV ink ha s a dye-component therein. The ink is jetted onto a substrate, the composition is cured, then heated to set the dye. Sublimation dye-based UV ink printing onto polyester is preferred. A release layer of protective material (702, 70 4) such as a TEFLON film or sheet, covers a substrate support (705, 706). A porous substrate to be printed, such as a textile material (711), is support ed on or above the support. Ink is jetted onto the substrate, with some of the ink passing through pores in the substrate and landing on the protective material. UV curable ink is preferably used and is exposed by UV light from a UV light curing head, which solidifies the ink on the substrate. The UV curi ng light has a long enough focal length to focus on the surface of the substrat e and also, where it passes through pores in the substrate, on ink on the protective material, thereby solidifying the ink on the protective material. When the substrate is removed from the support, the solidified ink on the protective material may be wiped from the protective material. The protectiv e material may be a coating on the support over which the substrate slides or a belt that moves with the substrate. A textile substrate may be preconditione d by singeing or shaving to remove fuzz from the fabric that could clog the printheads. A printhead cleaning station is also provided.

Title: Radiant field management for infant care apparatus
Inventor: MACKIN MICHAEL H
IPC: A61F7/00
Filed: 2003-10-28
Abstract: An infant warming apparatus that has a canopy vertically movable with respect to an infant resting on an infant between a lower position wherein the apparatus functions as an incubator and an upper position where the apparatus functions as an infant warmer. A radiant heater is located on the canopy and directs infrared energy in a first path towards the infant platform to warm the infant when the canopy is in the upper position. When the canopy is moved to its lower position to act as an incubator, the infrared energy is redirected along a second path that is directed away from the infant platform so as to prevent residual infrared energy that continues to be emitted even after discontinuing power to the radiant heater from affecting the infant as that radiant heater is moved to a position in close proximity to the infant.

Filed: 1996-05-17
Abstract: An interactive cable television system is disclosed which utilizes a standard cable television distribution network for simultaneously providing a plurality of viewers with an interactive television program comprising a plurality of signal related in time and content. Video signals (1) are transmitted in a digital format, more than one signal being multiplexed onto a data stream on a single channel. The video signals (1) may be compressed for efficiency. A receiver (7), in conjunction with a signal selector (8), selects a particular NTSC channel for playback, then selects a particular video signal from the data stream, and decompresses the video signal for playback. Seamless switching between video signals on different channels is provided. An alternative embodiment is disclosed wherein the various signals which comprise the interactive program are switched at the head end (300) rather than at the receiver (7). The multiple choice control unit (9) selects a desired signal by relating the multiple choice selections of the user through a relay box (17) back to a remotely located switching station. The switching station routes the correct video signal down the appropriate cable channel for the particular user.
