Abstract: A radar processor is disclosed for processing the radar return samples  from a Doppler radar receiver to discriminate helicopter targets from fixed-wing targets. The samples are passed through a helicopter filter which eliminates the target skin Doppler return, and passed the sidebands about the target skin return which are due to the helicopter rotor hub modulation.  The coefficients of the helicopter filter are selected to maximize the signal-to-noise ratio.  The radar processor requires only a few milliseconds on target  for reliable detection and can, therefore, be easily implemented by scanning surveillance systems.

Title: Method and apparatus for detecting double fed sheets
Inventor: CHANG SUNG S
IPC: B65H7/12
Filed: 1993-10-06
Granted: 2004-01-20
Abstract: A method and apparatus for detecting double fed sheets.      A sheet passes beneath a roller which is mounted on a lever so that the opposite end of the lever is deflected by an amount proportional to the thickness of the sheet. A magnet is attached to the opposite end of the lever approximate to a Hall Effect sensor fixed to the frame of the apparatus so that the hall sensor produces a signal proportional to the thickness of the sheet. The output of the hall sensor is sampled by an A/D convertor and the signals are input to a computer for processing to detect double fed sheets. Average thicknesses for subsequences of samples distributed over the sheet are computed and compared to reference levels. The length of the sheet is also compared to a reference length.      If, for any of these comparisons the measured values are greater than the references a doubled detect signal is generated. In one embodiment leading and trailing edges of the sheet may be detected by detecting transitions in the sequence of signals which are greater than the design minimum sheet thickness. In another embodiment of the subject invention the reference levels are established by first measuring a selected, assured single, initial sheet. In another embodiment of the subject invention the references are updated after each sheet by combining a portion of the previous reference value, preferably 7/8th's, with a portion, preferably 1/8th, of the measure value multiplied by an appropriate scale factor.

Abstract: A seed and fertilizer boot is mounted on a conventional cultivator shank. The boot has side-by-side fertilizer and seed tubes. One tube leads to a downwardly and rearwardly sloping delivery spout while the other delivery tube projects below the delivery spout. A flat knife is mounted on the front of the straight delivery tube to form a narrow furrow immediately in front of the associated delivery tube for receiving seed or fertilizer from the tube. The knife is adjustable along the tube so that its depth can be adjusted to compensate for wear. A second knife extends along the front face of the delivery spout to form a second furrow immediately beside the first furrow. This closes the first furrow and packs the soil onto the planted seed or fertilizer. The second knife also provides a shallower furrow for planting fertilizer or seed as the case may be. Like the first knife, the second knife is adjustable. Where desired, a skid-type packer can be mounted on the shank to close the furrows.

Title: Fluid jet surgical cutting tool
Inventor: BAIR SCOTT
IPC: A61B17/3211
Filed: 1994-07-08
Granted: 2006-01-03
Abstract: A pulsed fluid jet surgical instrument includes a cannula extending from a handpiece, the cannula emitting a pulsed fluid jet for cutting and emulsification purposes, and also providing suction for aspiration and evacuation of the fluid and tissue. A pressure intensifier piston arrangement receives fluid at relatively low pressure, and operates reciprocally and reiteratively to pump the fluid through the jet needle in a series of high pressure pulses, each having a nearly rectangular pressure waveform. The pressure intensifier piston is T-shaped, including a broad end which divides a drive bore into a driving chamber and a retracing chamber.  A bistable valve is connected to admit high pressure gas into the actuating chamber, driving the piston to translate. The narrow end of the piston is disposed in a fluid pumping chamber connected to a supply of fluid. The translating piston drives the fluid from the pumping chamber through a first check valve into a fluid jet needle, which directs the high pressure fluid pulse to a tissue target. The bistable valve switches to admit pressurized gas to the retracting chamber, driving the piston retrograde and allowing the pumping chamber to refill with fluid through a second check valve. There is no high pressure fluid supplied to the handpiece, and only the pressure intensifying pumping action of the piston creates a high pressure fluid pulse. The gas supply to drive the piston is t a relatively low pressure, so that gas pressure cannot comprise a safety risk to the patient. Thus failure of the piston mechanism cannot result in the emission of a stream of high pressure fluid, and the instrument is inherently safer than prior art instruments that are connected to a high pressure fluid source.

Abstract: A log processing method and apparatus are described in which the log is moved laterally through a light scanner by a pair of charger arms to determine the configuration of the log and the best cutting pattern solution for such log by a computer from the scan data.      The log is skewed by adjusting the length and angular position of the charger arms to align the central axis of the log with the center of the cutting pattern solution. Then the log is swing by pivoting the charger arms into a transfer position where the log is transferred to an end dogging log carriage. After transfer, the log is rotationally repositioned into the desired cutting position by rotating it about a selected chuck of a plurality of chucks on one end dog with a driven dog blade on the other end dog which is aligned with the centerline of the cutting solution. After repositioning the log is clamped against further rotation by extending additional end dog chucks into engagement with the log. Then the clamped log is conveyed on the carriage through the cutting devices.      One of the cutting devices is a bottom chipping head which is vertically adjusted in height by the computer during cutting to produce a curved or straight bottom surface on the log.
