Title: Method of compressing digital images
Inventor: HU XIAOPING
IPC: G06T9/00
Filed: 2002-02-18
Abstract: A method of compressing digital representations of images stores the images in multiple subsampling quality scales in a progressive manner such that a higher quality scale contains only data incremental to the data in an adjacent lower quality scale. The data in each quality scale is transformed, quantized, and entropy encoded. A discrete wavelet cosine transformation combining frequency transformation features of a discrete cosine transformation and spatial transformation features of a wavelet transformation is provided. Sequences of subsampling quality scales are provided for multi-scale representations of images. A novel context selection method is used which treats color components and coefficients of different positions differently. An image compressed in a given quality scale can be transmitted or decompressed progressively allowing progressive downloading or transmission over the Internet.

Title: Automatic eaves trough downspout
Inventor: CHEREMSHYNSKI DAVID L
IPC: E04D13/08
Filed: 2002-08-22
Abstract: An automatic eaves trough downspout includes a first conduit and a second conduit. The first conduit has a coupling socket. The second conduit has a hollow cylindrical coupling body is adapted to fit in the socket to form a pivotal connection. The cylindrical coupling body pivots on a pair of pivot pins. A torsion spring overlies one of the pivot pins. A first end of the torsion spring is secured to the cylindrical coupling body. A second end of the torsion spring is secured to a head of the pivot pin. Rotation of the pivot pin in a first direction increases the tension of the torsion spring. The torsion spring biases the second conduit into the substantially vertical stored position. A ratchet engagement is provided between the head portion of the pivot pin and the socket of the first conduit, which permits rotational movement of the pivot pin in the first direction to increase spring tension and resists rotational movement in the second direction.

Title: Single feed, multi-element antenna
Inventor: APOSTOLOS JOHN T
IPC: H01Q9/28
Filed: 2001-04-27
Abstract: An array antenna (200) capable of use with a single signal feed has a transmission line oriented substantially parallel to a ground plane (220), which transmission line has a multiplicity of sequential sections with each sequential section having a different spacing from the ground plane (220) than each of its immediately adjacent sequential section. This stepped or varied impedance transmission line forms an array in which the sections spaced further from the ground plane (220) become active antenna elements.  Controlling an electrical spacing between the ground plane (220) and transmission line provides relative phase control between the active elements and thereby phased-array directional control of the antenna.
