Title: A method for immobilizing or killing swimming larvae in a mass of fresh water, and an electric trap for practising such a method
Inventor: OSTLIE LARS STEINAR
IPC: H05C1/02
Filed: 1992-04-03
Abstract: 2107572 9217061 PCTABScor01 A trap for swimming larvae in fresh water is constituted by two capacitor plates for influencing a mass of fresh water between the plates. An alternating current flowing in the interior of the larvae is able to kill the larvae, and the power dissipation of the trap is limited substantially thereto, while the effect of heating up the mass of water is avoided, since fresh water is a poor conductor. Therefore, it is sufficient with a voltage generator which supplies a relatively low power, i.e. a relatively high voltage but a limited current. In a method where the trap is used, a concentrated electric power dissipation of an immobilizing or killing magnitude is caused in the interior of the larvae. The interior of the larvae is constituted substantially of an electrically highly conductive liquid, and when an alternating electric field is established in the water between the capacitor plates, there will be an alternating polarization of both water mass and larvae, and an alternating current is caused inside the larvae.

Title: Adaptive block size image compression method and system
Inventor: LEE CHONG U
IPC: H04N7/26
Filed: 1992-06-03
Abstract: An adaptive block size image compression method and system for compressing image data, a respective method and sys-tem for further compressing the image data for transmission. Each block and corresponding sub-blocks of pixel data is subjected to a discrete cosine transform (DCT) operation (10a-10d). Varying levels of sub-blocks of resulting corresponding transform coef ficients (12a-12d) are selected for construction into a composite transform coefficient block (QC) corresponding to each input block of pixel data. The selection of transform coefficient block size for the composite block is determined by a comparison pro-cess (20, 26, 32) between transform block and sub-block coding efficiency. The composite block is variable length coded to further reduce bit count in the compressed data. A discrete quadtree transform (DQT) operation is in supplement of the adaptive block size block selection with coefficient replacement to optimize image data compression.
