Abstract: A convertible stand for concealing an inflatable mattress that converts into a headboard when the inflatable mattress is inflated. The convertible stand has a compartment. A pliable material is connected to the inflatable mattress. A portion of the pliable material extends beyond an end of the inflatable mattress and is connected to an inner wall surface of the compartment. A barrier is connected to the convertible stand. When the barrier is oriented in an upper position the compartment is open and the inflatable mattress can be inflated. When the barrier is oriented in a lower position the compartment is closed and both the deflated inflatable mattress and pliable material are retained within the compartment of the convertible stand.

Abstract: A micro device includes a substrate and a structure configured to bind to an object or a material, or not to bind to an object or material. The structure has a roughness based on a roughness of the object or material. For example, a microarray includes a substrate and a well positioned in the substrate and configured to bind to a type of bead. The well has a roughness based on a roughness of the type of bead to which the well is configured to bind. The roughness of the well is controlled by controlling a position and number of striations in the side of the well. In another example, a moveable component of a micro device may have a roughness different from a roughness of an adjacent component, to reduce the likelihood of the moveable component sticking to the adjacent component.

Abstract: A method for introducing and expressing genes in animal cells is disclosed comprising infecting said the animal cells with live invasive bacteria, wherein bacteria contain a eukaryotic expression cassette encoding said gene. The gene may encode, e.g., a vaccine antigen, an therapeutic agent, an immunoregulatory agent or a anti-sense RNA or a catalytic RNA.

Abstract: A method for introducing and expressing genes in animal cells, in which the animal cells are transfected with bacterial blebs containing a eukaryotic expression cassette encoding the gene. Bacterial blebs comprising a eukaryotic expression cassette, wherein the bacterial blebs are derived from gram negative bacteria.

Abstract: The present invention provides gram-negative bacterial strains that produce substantially pure non-pyrogenic lipopolysaccharide or lipid A. The present invention also relates to a use of said strains for the preparation of non-pyrogenic DNA and use of the same for introducing endogenous or foreign genes into animal cells or animal tissue. Further, the present invention relates to a use of said strains for the preparation of non-pyrogenic recombinant mammalian, protozoan and viral proteins. Furthermore, the present invention relates to a use of said strains for the preparation of non-pyrogenic bacterial vaccines and vaccine vectors. Yet a further use of the present invention relates to a use of said strains for the preparation of non-pyrogenic bacterial proteins and polysaccharides antigens for use as vaccines.

Abstract: Unwanted electric fields in the area in front of a CRT can be produced by flyback voltage pulses which occur across the horizontal deflection coils and are coupled to the inner DAG coating of the CRT. The unwanted fields can be eliminated by providing voltage pulses equal and opposite to the causative voltage pulses and applying the provided voltage pulses to the inner coating and the anode button, leaving no fields to be cancelled in the relevant area.

Abstract: An arc protection circuit is disclosed for protecting a component, such as a transistor, from the effects of arcs developed in a CRT. The protection circuit includes an arc sensing circuit coupled to the component to be protected so as to sense the presence of an arc-induced transient voltage, in response to which the sensing circuit rapidly assumes a first state. An active current switch is coupled to the protected component and is responsive to the first state of the sensing circuit for rapidly assuming a low impedance state to shunt arc-induced current away from the component.
