Patent number: 10429482Abstract: A method for characterization of fixture utilizes a mirror symmetric THRU structure and either a HALF-THRU with a LOAD shunted to ground or a THRU with a LOAD shunted to ground located at the mirror reference plane. The method extracts the short, open, and thru measurements from the THRU structure due to the mirror symmetry. The HALF-THRU with a LOAD or the THRU with a LOAD shunted to ground located at the mirror reference plane provides the independent measurement to fully characterize the fixture. The resultant impedance or scattering parameter HALF-THRU model may be used in de-embedding a Device-Under-Test, a calibration routine, or computational simulations. The parameters of a HALF-THRU model may be stored in a memory storage circuit affixed to the associated HALF-THRU fixture. Some embodiments may include at least one memory storage circuit that attaches to the HALF-THRU fixture body affixed to an interposing matable connector.Type: GrantFiled: May 30, 2014Date of Patent: October 1, 2019Assignee: Oracle International CorporationInventors: James M. Frei, Jyotika Singh, Connie K. Szeto, Ryan Travis Caldwell, Kenneth F. Hatch

Patent number: 9462206Abstract: A module for high speed image processing includes an image sensor for generating a plurality of analog outputs representing an image and a plurality of HDDs for concurrently processing the plurality of analog outputs. Each HDD is an integrated circuit configured to process in parallel a predetermined set of the analog outputs. Each channel of the HDD can include an AFE for conditioning a signal representing one sensor analog output, an ADC for converting a conditioned signal into a digital signal, and a data formatting block for calibrations and formatting the digital signal for transport to an off-chip device. The HDDs and drive electronics are combined with the image sensor into one package to optimize signal integrity and high dynamic range, and to achieve high data rates through use of synchronized HDD channels. Combining multiple modules results in a highly scalable imaging subsystem optimized for inspection and metrology applications.Type: GrantFiled: May 7, 2014Date of Patent: October 4, 2016Assignee: KLA-Tencor CoporationInventors: David L.

Patent number: 4051373Abstract: A scintillation camera system including compensated delay line clipping circuitry for narrowing data representing pulses in the system without introducing base line undershoot and a restoring circuit for minimizing base line fluctuation of a data signal. The compensated circuitry includes a single delay line circuit for clipping an incoming data pulse having a relatively long trailing edge. A variable resistor is coupled with the circuit for controlling amplitude and polarity of the unclipped, incoming data pulse. A value of this unclipped pulse is controllably summed with the clipped pulse for correcting delay line attenuation and base line undershoot. The restoring circuit is combined with the single delay line clipping circuit for restoring the base line of the single delay line clipped pulses. The restoring circuit produces double delay line clipped timing pulses from the single delay line clipped waveform pulses.Type: GrantFiled: July 28, 1975Date of Patent: September 27, 1977Assignee: Picker CorporationInventor: Kenneth F.

Patent number: 4024398Abstract: A nuclear imaging system includes an analog signal processor which features analog data derandomization for minimizing data loss due to pulse pile-up. A scintillation detector provides a sequence of analog data pulses to the signal processor, the data pulses characterizing the energy level and situs of respective radiation events striking the detector. The signal processor includes sets of novel peak detectors and of sample and hold circuits which are serially connected and are operated to derandomize or space the sequence of analog data pulses so that the system can process pulses corresponding to photopeak events occurring only 1.5 microseconds apart. The analog data pulses are stored in analog pulse form in the peak detectors and are selectively transferred into the sample and hold circuitry from which they are transferred to the display mechanism. The signal processor is multiplexed with several data input channels for accommodating dual isotope operation.Type: GrantFiled: May 12, 1975Date of Patent: May 17, 1977Assignee: Picker CorporationInventor: Kenneth F.
