Title: Soil zone-builder coulter closer/tiller with improved downward coulter pressure and shank head
Inventor: SMITH DAVID R
IPC: A01B49/02
Filed: 1999-01-20
Abstract: An apparatus and method for tilling a seedbed with a soil manipulation device comprising a tilling shank for forming a groove in the soil followed a pair of coulter blades for closing the groove and a rear finishing device such as a rolling basket for further tilling and firming of the soil with improved coulter downward pressure and shank head. Downward pressure on the coulter blades is provided by a coulter spring attached to a lever arm pivotally attached to the framework which applies downward pressure to the framework supporting the coulter blades. The rear finishing device is connected to the same coulter support framework by a pivotal rear arm and a rear arm spring such that when the rear finishing device is displaced upward by changing field conditions, an upward force is imparted to the coulter support framework thus raising the coulter blades in response to changing field conditions. Further, a shank head is disclosed which has narrow leading center point flanked on either side by secondary points placed behind the behind the center point and which breaks up soil hardpan with a minimum of soil disturbance at the surface.

Inventor: KROHN WILLIAM T
IPC: G01J1/02
Filed: 1998-07-31
Abstract: An energy beam threat dis-crimination system (110) adapted for use with laser beam energy (134). The system (110) includes a first detector (114) for detecting a first laser signal. A second detec-tor (112) detects a coherent laser signal. A timer circuit (124, 126) establishes a time interval between the detection of the first laser sig-nal and the detection of the coher-ent laser signal and provides an output (130) in response thereto.      A control circuit (128, 130) deter-mines, based on the output (130), if the first laser signal and/or the second laser signal is threatening.      In a specific embodiment, the first detector (114) provides an event detection flag (118) as an output in response to the detection of a first laser signal. The first detector (114) includes a high sensitivity laser light detector (142), a pre-amplifier (144), and an analog threshold circuit (146). The coherent detector (112) provides a coherent detection flag (116) as an output in response to the detection of the coherent laser signal. The timing circuit (124, 126) receives the event detection flag (118) as input and includes a digital clock circuit (124) that starts a timer (126) upon receipt of the event detection flag (118). A digital comparator circuit (128) is activated by the receipt of the coherent detection flag (116) which triggers a comparaison between the output (130) of the timer circuit (124, 126) and a time threshold (131) and provides a reflection signal output indicating if the laser signal is a potential threat or not. The time threshold (131) for determining that the laser signal is a potential threat is approximately 10 nanoseconds. Alternatively, the time threshold for determining that the laser signal is not a potential threat is approximately 40 microseconds.

Title: Inspection of containers employing a single area array sensor and alternately strobed light sources
Inventor: JUVINALL JOHN W
IPC: G01N23/18
Filed: 1999-05-19
Abstract: Apparatus for inspecting a container that includes a first light source for generating light energy of a first character and directing the light energy onto a predetermined portion of a container under inspection, and a second light source for generating light energy of a second character different from the first character and directing such light energy onto the same predetermined portion of the container under inspection. An area array light sensor is disposed to receive a two-dimensional image of the portion of the container illuminated by the first and second light sources. The first and second light sources are sequentially and alternately strobed, and first and second two-dimensional images of the container portion under inspection are downloaded from the sensor. Commercial variations that affect optical properties of the containers are identified by comparing the first and second two-dimensional images from the respective light sources scanned from the sensor. The sensor preferably includes facility for scanning two-dimensional images in sequential frames, and the first and second images are obtained by scanning sequential frames from the sensor during which the first and second light sources are alternately strobed.

Abstract: A phase locking oscillator (70, 80, 90, or 110) and a radio frequency oscillator (72, 82, 92, or 112) achieve reduced incidental frequency modulation by reducing a frequency-deviation-sensitivity. The frequency-deviation-sensitivity is reduced by a voltage divider (66 or 100) that reduces a frequency-control voltage, thereby decreasing the frequency-deviation-sensitivity, along with voltage spikes and other electrical noise, and thereby reducing incidental frequency modulation. The reduction in frequency-deviation sensivity also reduces a maximum frequency range of the radio frequency oscillator (72, 82, 92, or 112) for a maximum frequency-control voltage, and reduces the capture range of the phase locking oscillator (70, 80, 90, or 110). Means is provided for at least partially restoring the reduced maximum frequency range of the radio frequency oscillator (72, 82, 92, or 112) and the capture range of the phase locking oscillator (70, 80, 90, or 110). The means for restoring includes a diode (78A), a transistor (88A), a PROM (96), or a counter (118) that provide an other voltage. The means for restoring also includes means (R5 and R10) for proportionally combining the other voltage with the reduced frequency-control voltage.

Filed: 1998-09-18
Abstract: The concentration of air or other agents in a fluid delivery line is determined by monitoring agent signals and processing those agent signals along with information regarding the age of each agent signal. The processor determines a primary agent concentration value based on the received agent signal values, with the primary agent concentration value determined by giving greater weight to more recent agent signal values. Where the primary agent concentration value exceeds a primary threshold value, an alarm signal may be activated.  The processor also may determine a secondary agent concentration value, which may be determined from the actual agent signal values instead of the weighted agent signal values. Where the secondary agent concentration value exceeds a secondary threshold value, an alarm signal may be activated.
