Sleeping bag on rollers which converts into a backpack

The present invention is a new, original and novel one piece sleeping bag / backpack with rollers that is folded and contained in an attached pocket cavity enclosure, and when folded becomes a square pillow. In addition, there is an optional matching small pillow that fits inside one of the many pockets contained on the sleeping bag for the child to use for his / her head when laying in the sleeping bag. The rollers / wheels are small and can be made with the rollers sewn and permanently attached to the bottom of the sleeping bag. The rollers are also conveniently attached with the use of snaps or Velcro® so that they can be removed for the washing machine. However, that is not necessary because the wheels are so small it causes no problem in the washing machine if they were permanently attached. If the wheels are attached it causes no discomfort to the child as they are positioned in such a way that the child does not notice them while sleeping or resting. However, in the removable ones, the child will have the option to remove them if he / she chooses. The invention uses both because in some cases the smaller younger children stand the possibility of losing or misplacing the wheels if they are removed while they are sleeping, whereas the parent may like the idea of removing them for the wash.

Copper (i) complexes for optoelectronic devices

ActiveUS20130150581A1Short possible emission decay timeDiminished roll-off behaviorFinal product manufactureGroup 5/15 element organic compoundsSolubilityChlorobenzene
The invention relates to neutral mononuclear copper (I) complexes for emitting light and with a structure according to formula (A) in which: M represents: Cu(I); L∩L represents: a single, negatively charged, bidentate ligand; N∩N represents: a diimine ligand (substituted with R and FG), in particular a substituted 2,2′-bipyridine derivative (bpy) or a substituted 1,10-phenanthroline derivative (phen); R represents: at least one sterically demanding substituent for preventing the planarisation of the complex in the excited state; FG=functional group, and represents: at least one second substituent for increasing solubility in organic solvents. The substituent can also be used for electron transport or alternatively for hole transport, said functional group being bound to the diimine ligands either directly or by means of suitable bridges; and the copper (I) complex: having a ΔE(S1−T1) value of less than 2500 cm−1 between the lowest excited singlet state (S1) and the triplet state (T1) which lies below; having an emission lifespan of at most 20 μs; having an emission quantum yield of greater than 40%, and a solubility of at least 1 g/L in organic solvents, in particular polar organic hydrocarbons such as acetone, methyl ethyl ketone, benzene, toluene, chlorobenzene, dichlorobenzene, dichloromethane, chloroform, dichloroethane, tetrachloroethylene, alcohols, acetonitrile or water.

Expansion card retention apparatus

An expansion card retention apparatus includes a rear panel (50), first and second retention brackets (10, 30), and a side panel (59). The rear panel defines a number of expansion slots (52) for receiving expansion cards (60) therein respectively, an opening, and a pair of hook openings adjoining the opening. The first retention bracket is rotatable in the opening between first and second positions, and includes a pair of hooks (16). The second retention bracket defines a number of flexible tongues (311). The first and second retention brackets are together rotated to the second position such that the flexible tongues engage corresponding expansion cards, and the hooks engages in corresponding hook openings of the rear panel. The side panel is attached to the rear panel for holding the first and second retention brackets in place. The expansion cards are thus securely attached to the rear panel.
