The present invention discloses an interactive IR electronic white board, around which is an infrared emitting and receiving array. An output port of a column driver of emitting array is connected to high frequency modulating signal generator, and an output port of a column driver of the receiving array is connected to a microprocessor through a signal receiving circuit and an analog-digital converter A / D. The emitting array and the receiving array are connected to emitting and the receiving driver through emitting and receiving driver lines, and the emitting driver and the receiving driver are connected with the microprocessor through address bus. The present invention utilizes the Inverse Square Law of optical theory and the linear direct ratio relation between the quantity change of light particles received by an infrared receiving diode and the output voltage of the receiving diode to associate the output voltage of the receiving diode with the interrupted width of the infrared light path, so that it can calculate the coordinate of interrupter accurately and improve the resolution of infrared scanning. The present invention can not only distribute pens or erase, but can be used by plurality of users at the same time as well.

UV-glossing for simplex and duplex prints, wherein an input member having thereon a pre-gloss toner image including UV-curable toner is moved, in non-slip association with a smooth UV-transparent web, jointly with the web through a plurality of process zones sequentially including a heating zone and an exposure zone, thereby producing an output member having a glossed, UV-cured, surface. In the heating zone, at least the outermost toner of the pre-gloss toner image is heated to a molten state in contact with the web. In the exposure zone, with the molten state being maintained, at least the outermost toner which contacts the web is cured by a flux of UV radiation transmitted through the web. In a preferred embodiment, the UV-curable toner is formed as an outer layer on the pre-gloss toner image.

A valve structure includes a valve body on which is mounted a first valve and a second valve. The first valve traverses the valve body at a first position and the second valve traverses the valve body at a second position spaced apart from the first position. The first valve may comprise a fill valve and the second valve may comprise a pressure relief valve. Alternatively, a single valve structure may incorporate both the fill and pressure relief functions. The valve structure may be incorporated with a bladder made of a flexible and elastic material. In this arrangement, the valve body is positioned in a valve receiving opening in the bladder material and is sealed to the bladder material around the periphery of the valve receiving opening so as to define a sealed bladder interior with the bladder material. Such a valve and bladder combination may be used together with a hull tube to form a portion of an inflatable hull for a boat.

Disclosed is a portable mattress topper apparatus and related methods for increasing the safety and comfort of children in play pens or play yards.

A tube coupling to receive and hold a tube (T) includes a coupling body (10) having a throughway with an annular step (24) facing an open end (12). An annular seal (25) is located in the coupling body adjacent to the annular step. An end cap (13) engages the coupling body and is axially moveable. A collett (17) in the cap has legs (20) with outer surfaces that engage with a tapered surface (23) in the end cap to urge the legs inwardly to grip the tube. The seal (25) is compressed axially in response to the forward movement of the end cap (13) to cause the tube end to be pressed into sealing engagement with the seal end. A biasing member (28) provides a biasing force to urge the legs (20) axially onto the tapered surface (23) when the cap is in the retracted position.

Apparatus, systems and methods for characteristics of glass components through use of one or more coatings are disclosed. The coatings are typically thin coatings, such as thin film coatings. The coatings can serve to increase strength of the glass components and / or provide durable user interfacing surfaces. Accordingly, glass articles that have received coatings are able to be not only thin but also sufficiently strong so as to resist damage from impact events. The coated glass articles are well suited for use in consumer products, such as consumer electronic devices (e.g., electronic devices).
