IPC: H01J61/04
Filed: 1999-03-02
Abstract: The invention relates to a discharge lamp (1) comprising an electrically conductive shielding (12, 13) which at least partly encloses the discharge chamber (2).

Title: Electronic circuitry for timing and delay circuits
Inventor: PATTI ROBERT S
IPC: H03K3/0231
Filed: 1998-06-16
Abstract: An electronic delay circuit (10) useful for the delayed initiation of detonators illustrates several novel features that may be combined, including a novel oscillator (34), a programmable timer circuit (32) and a run control circuit (46). The oscillator (34) generates a clock signal determined by the rate of discharge of a capacitor (34a) relative to a reference voltage REF. A  second capacitor (34b) is charged to a voltage that exceeds REF, and when the first capacitor (34a) falls below REF, an internal signal is generated and the capacitors are switched, so that the first capacitor gets charged while the second is discharged. A latch (34f) produces clock pulses in response to the internal signals. The programmable timer circuit (32) includes a ripple counter (38) and a program bank (40) that loads a count in the counter upon initialization. Each stage of the counter (38) has separate inputs for set and clear signals, and the program bank (40) has a setting circuit and a clearing circuit for each counter stage. Each clearing circuit generates a signal of fixed duration and each setting circuit can generate a signal of two different durations, one of which exceeds the clear signal. During programming, the set signal of short or long duration is chosen and, in loading the counter, the longer of the set signal or the clear signal determines the state of the counter stage. The run control circuit (46) controls a gate (34h) that permits oscillator pulses to increment the counter (38), but closes gate (34h) should a temporary loss in power occur thus preventing the timer (32) from being re-initialized.

Title: Method and system for automated detection of clustered microcalcifications from digital mammograms
Inventor: ROGERS STEVEN K
IPC: G06T5/20
Filed: 1998-08-28
Abstract: A method, a system for detecting, and displaying clustered micro-calcification in a digital mammogram wherein a single digital mammogram (100) is first automatically cropped (200) to a breast area sub-image which is then processed by means of an optimized difference of a Gaussian filter to enhance the appearance of potential micro-calcification in the sub-image. The potential micro-calcification is threshold, clusters are detected (300), features are computed for the detected clusters, and the clusters are classified (400) as either suspicious or not suspicious by means of a neural network. The locations in the original digital mammogram of the suspicious detected clustered micro-calcification are indicated. The results of the system are optimally combined with a radiologist's observation of the original mammogram by combining the observations with the results after the radiologist has first accepted or rejected individual detections reported by the system.
