Title: Photocatalytic air treatment process under room light
Inventor: WATANABE TOSHIYA
IPC: A61L9/16
Filed: 1993-11-05
Abstract: A process for photocatalytically treating a hospital room contaminated by bacteria or an interior environment bearing airborne malodorous substances. A thin film of photocatalyst made of semiconductor such as titanium dioxide is disposed on the inner wall of the hospital room or living space. The photocatalytic thin film is irradiated by a light source of general lighting applications, such as a fluorescent lamp, and is photoexcited by a small amount of ultraviolet radiations included in the light of fluorescent lamp. The wattage of the fluorescent lamp as well as the distance between the photocatalytic thin film and the lamp are selected such that the intensity of those UV radiations which have a higher energy than the band gap energy of the photo-catalyst is 0.001-1 mW/cm2, preferably, 0.01-0.1 mW/cm2. The bacteria and chemical compounds deposited on the photoexcited thin film are photodecomposed.

Title: Rapid feature introduction in telecommunication networks
Inventor: NORELL BROR L
IPC: H04Q3/00
Filed: 1993-08-12
Abstract: The invention relates to a telecommunication system provided with resources and with software which controls the individual resources and also the manner in which the resources cooperate mutually at a system level.  In accordance with the invention, the software is divided into two parts.  The first part, called object logic, comprises a number of object units each of which represents an individual type of resource.  Further, each object unit includes operations for controlling its individual resource.  An individual type of resource may be used for a number of different purposes.  The second part, called control logic, includes a number of control cases.  Each control case, in turn, combines a number of object units in a superordinate fashion, to control the mutual cooperation of corresponding resources irrespective of the manner in which an individual object unit is intended to influence its resource.  A control case includes a number of control stages, each of which has only one input, at least a first operation, called control stage operation, and at least one output.  The control stages of a control case are mutually connected by links, each of which is designed to connect an output of a preceding control stage with the input of a following control stage.  The points at which links are connected to the control stages are called potential connection points to which additional control cases, called control case features, can be connected to the control case in which the control stages are present, called the basic control case, for modification of the basic control case.
