Patent CA-2447138-A1 (CA)
Inventor: FURUHASHI KENJI
IPC: F24F3/16
Filed: 2002-04-19
Abstract: A switching transformer applies an alternating high voltage across an intern al electrode and an external electrode which face each other with a glass tube as a dielectric body between them. The anode side of a diode is connected to th e external electrode which is not a voltage supply side electrode, while the cathode side is grounded. When a relay connected to both the terminals of th e diode is turned on, substantially equal amounts of positive ions and negativ e ions are generated, and a bacteria removal/disinfection effect can be obtain ed by emitting these positive ions and negative ions into the air. When the rel ay is turned off, a relatively small amount of positive ions and a relatively large amount of negative ions are generated, and a relaxation effect given b y negative ions can be obtained by emitting these positive ions and negative ions into the air.

IPC: G06F21/00
Filed: 2003-11-12
Abstract: A computer system attempts to authenticate with a server to gain authorization to access a first network. It is determined by the server that the computer system is not authorized to access the first network. The computer system is given authorization to access a second network for at least the purpose of downloading files (e.g., signup and configuration files) needed to access the first network. A user-interface for receiving user-entered signup information is automatically presented at the computer system.  A first schema-based document including user-entered information is transferred to the server. If the server determines that the user-entered information is appropriate, a second-schema document, which includes an indication of authorization to access the first network (e.g., a user-identifier and password), is received. A third schema-based document is executed at the computer system to compatible configure the computer system for accessing the first network.
