  • Publication number: 20100060082
    Abstract: A digital camera includes: a battery installation part connectable to either an AC adapter or a battery; a mechanical shutter and a diaphragm; and a controller for supplying, to the mechanical shutter and the diaphragm, power from the AC adapter or battery that is connected to the battery installation part. The controller monitors a voltage output through the battery installation part during the power supply to the mechanical shutter and the diaphragm, and determines whether or not the AC adapter is connected to the battery installation part in accordance with the behavior of the monitored voltage changes.

  • Publication number: 20080235798
    Abstract: A method of filtering junk messages has the steps of generating an implicit code, adding the implicit code to an message to be sent to an addressee, sending the message with the implicit code and a sender's address to the addressee from a sender, and determining whether the implicit code in the message matches a local reference code corresponding to a sender being recorded in an addressee's contact list. The message is correctly received in a normal message box if the implicit code matches the local reference code, otherwise the message is blocked.

  • Publication number: 20050214182
    Abstract: This invention is a type of ozone generator module whose circuit board is contained in a small shell-shaped box, which is connected to an external power supply through wires extending from the body of the box. The interior of this insulated box is covered in a layer of resin that surrounds and insulates (electric and heat) the circuit board. This allows the components necessary in the production of the ozone gas (such as the electrode pins and electrode board needed for point diffusion, or the ultraviolet light tube or ceramic parts necessary for ozone generation by the ultraviolet light method) to produce and diffuse ozone gas outside the body of the box. This allows the ozone generator to meet the requirements for its downscaling and modulation, and allows the broadening of its application range.

  • Patent number: 5651108
    Abstract: A system of the present invention includes a relational database management system (RDBMS), having an object-based, interactive visual-programming language providing programming by "visual inheritance." A user places screen objects (e.g., boxes, screen buttons, table objects, and the like) on an on-screen window or "form," visually attaches selected "properties" and "methods" to the screen objects, and then establishes an containership-based event model that dictates how and when these properties and methods will be invoked. An object inherits (derives) properties and methods from other (parent) objects via its visual containership. In this manner, the task of creating and maintaining application programs is greatly simplified.
