The present invention relates to a multiple-dimension-data-organization method. More specifically, this method uses an n-dimensional cube (M-cube) in which each face displays the data on a 2-D planar surface and in which the x and y axes may be changed in accordance with the user's request. More specifically still, the data to be viewed may be easily changed by the user by means of a simple rotation command using a touch-sensitive interface.

A multi-pass parallel tube heat exchanger is disclosed. The multi-pass parallel tubes heat exchanger provides a compact, light and inexpensive heat exchanger that may be oriented in any direction. These features and others make the disclosed exchanger ideal for use in a restricted area such as that available when providing localized cooling systems. This design is more efficient than the prior art and allows for a versatile operation with multiple circuiting options for the flow path and enhanced performance with multiple fluid and heat transfer operations.

A latent image developing system, a novelty kit, and an ink composition for printing latent images on a substrate. The latent image developing system includes a first substrate containing a colorless image deposited on a first surface thereof. A developer component is provided that is reactive with the colorless image to provide a visible image. The developer component is selected from a developer instrument, a developer finger paint, a developer coating on a first surface of a substantially transparent substrate for adhesive attachment to the first substrate, and a combination of one or more of the developer instrument, the developer finger paint, and the developer coating. The latent image developing system optionally includes, an image blocking instrument for concealing at least a portion of the visible image. The image blocking instrument includes a blocking composition applicator and an aqueous mixture of blocking composition and water.

A method for facilitating the upgrade of an inkjet printer of a type including a pagewidth printhead, the method including the steps of providing the inkjet printer as a complementary cradle and starter cartridge wherein the cradle is arranged to operate a number of cartridges having differing performance characteristics, facilitating replacement of the starter cartridge with another of said number of cartridges having an improved performance characteristic.

The invention provides a drawing device used for construction budget drawing, and belongs to the technical field of drawing tools. The device is used during construction budget drawing. According to the technical scheme, the drawing device is characterized in that a work table is a rectangular box, a protecting flip cover is positioned on the upper surface of the work table, the rear end of the protecting flip cover is in hinging connection with the rear end of the work table through a rotation shaft, support legs are mounted at the two ends at the lower side of the work table, the support legat each end is U-shaped, the middles of the two support legs cross and are connected through a folding rotation shaft, two moving rolling wheels are mounted on the two sides of one end of the work table, a front storing box is mounted on the front end face of the work table and a side storing box is mounted on the end face of one side of the work table, the front storing box and the side storingbox are in sliding fit with slideways, and a chargeable inside power supply is mounted inside the work table. The drawing device is simple in structure and convenient and stable in use, the work environment is improved, folding and movement are available, then the device is suitable for different work occasions, meanwhile, the device can be used for storing various drawing tools, and thus the usedemand for drawing mapping of construction budget of workers is satisfied.
