Patent MX-9804832-A (MX)
Title: Temperature transmitter with on-line calibration using johnson noise.
Inventor: ERYUREK EVREN
IPC: G01K15/00
Filed: 1998-06-16
Abstract: A temperature transmitter (10) and a process control system includes a sensor input (1, 2, 3, 4) for coupling to a temperature sensor (16) having a temperature dependent resistance. Resistance measuring circuitry (20, 26, 50) couples to the sensor input (1, 2, 3, 4) and provides a resistance output related to resistance of the temperature dependent resistance. Analog to digital conversion circuitry (78, 88) couples to the sensor input (1, 2, 3, 4) and provides a digital output related to AC signals across the sensor input. Digital signal processing circuitry (64) isolates a Johnson noise component of the AC signals and provides a digitized Johnson output. Temperature measurement circuitry provides a calibrated temperature output based upon the resistance output and the digitized Johnson noise output. Output circuitry (24) transmits the calibrated temperature output over the process control loop (11).

Inventor: MARCUS ADRIANUS VAN DE KERKHOF
IPC: G03F7/20
Filed: 2019-05-10
Abstract: Disclosed herein is a lithographic apparatus, comprising: an illumination sy stem conﬁgured to condition a radiation beam; a patterning device (601) configured to impart the radiation beam with a 5 pattern in its cross-section to form a patterned radiation beam; a pellicle (602) conﬁgured to cover a surface of the patterning device (601); a substrate table configured to hold a substrate; a projection system conﬁgured to project the patterned radiation beam onto a target portion of a substrate when the substrate is held by the substrate table, wherein the projection system comprises one or more optical elements; a first set of one or more outlets (603) for outputting a ﬁrst ﬂuid into a first region, wherein 10 the first region abuts and/or comprises the pellicle (602); and a second set of one or more outlets (605) configured to output a second ﬂuid into a second region that comprises the one or more optical elements of the projection system; and wherein the second ﬂuid is different from the ﬁrst ﬂuid. Advantageously, the ﬂuid in the ﬁrst region protects the pellicle (602) from damage by the ﬂuid in the second region. A pellicle that would otherwise be damaged by the ﬂuid in the second region can 15 therefore be used.

Patent NL-8600754-A (NL)
IPC: G06F9/445
Filed: 1986-03-25
Abstract: A system for providing information to alter the software of an electronic data processor embedded in an electronic module includes a remote reprogramming module that conducts a sequence of operations to provide data to the processor which the processor uses to reprogram itself. The system employs a data link having a bi-directional transmission path connecting the processor and the reprogramming module. A controlled switching circuit is provided at each end of the transmission path. Under normal operating conditions, the transmission path is used to transit a function signal for a function performed by the electronic module. Periodically, the processor operates one switching network to capture the path for transmission of a reprogramming inquiry signal to the reprogramming module. At the same time, the function signal is diverted to an alternate path internal to the electronic module. When the reprogramming module detects a reprogramming inquiry, it operates the other switching circuit to gain access to the transmission path. Then, in response to commands from the processor, the reprogramming module undertakes the reprogramming sequence and transfers data to alter program information held in the memory of the processor. Thereafter, both the processor and the reprogramming module operate their respective switching circuits to restore the transmission path to its normal operational use for the transmission of the function signal.

Title: Circuit cancelling moire interference in colour CRT
Inventor: RINDAL ABRAHAM E
IPC: H04N5/68
Filed: 2001-07-11
Abstract: Visible Moire interference is eliminated by alternately shifting the phase of the horizontal sync signal or video signals such that the phase of each video line, and hence the phase of the resulting Moire interference associated with that video line, is also alternately shifted. The phase of the Moire interferences are shifted such that persistence of vision in the human eye averages oppositely phased phosphor intensity variaitons occurring on alternating scan lines and/or vertical fields. When viewed by a user of the CRT, optical cancellation of the Moire interference patterns results.
