Title: Method of compressing digital images
Inventor: HU XIAOPING
IPC: H04N1/41
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.

Inventor: POLISHCHUK VOLODYMYR
IPC: G01T1/02
Filed: 2010-04-28
Abstract: This invention provides a radiation dosimeter and new method of operation which comprise two types of the metal-oxide-semiconductor field-effect transistor (MOSFET) circuits allowing to amplify the threshold voltage changes due to radiation and provide temperature compensation. The first type dosimeter is a radiation integrated circuit (RADIC) which includes two radiation field-effect transistors (RADFET) and two MOSFETs, integrated into the same substrate. The second type of radiation circuit includes two RADFETs, integrated into the same substrate, and two resistors.  The amplification of the threshold voltage change is achieved by using amplification principles of an MOSFET inverter. In both cases, under the ionizing irradiation, the gate of first RADFET is forward biased and the gate of second RADFET is biased off.  In the reading mode the amplified differential threshold voltage change is measured.  The increased radiation sensitivity allows to measure of the milli-rad doses. The temperature effect and drift is substantially eliminated. These radiation integrated circuits can be used as a personal dosimeter in the nuclear, industrial and medical fields.

Inventor: WEIGHTMAN RUSSELL
IPC: H05B41/392
Filed: 2008-10-21
Abstract: A dimmer switch for controlling the intensity of a dimmable screw-in compact fluorescent lamp provides smooth dimming of the fluorescent lamp and prevents flickering of the lamp due to multiple re-strikes. The dimmer switch prevents multiple re-strikes by avoiding multiple firings of a controllably conductive switching device of the dimmer circuit by limiting the high-end light intensity of the fluorescent lamp. Specifically, the dimmer switch limits the length of a conduction interval of the controllably conductive switching device to less than approximately 75% of each half-cycle.  The dimmer switch may include a user-accessible adjustment actuator for changing the dimmer switch between an incandescent operating mode and a screw-in compact fluorescent mode. The dimmer switch may also be operable to automatically change the dimmer switch between the incandescent operating mode and the screw-in compact fluorescent mode by detecting the occurrence of the multiple firings of the controllably conductive switching device.
