Title: Method and apparatus for cutting poultry hind quarters
Inventor: POLKINGHORNE ROBERT F
IPC: A22C21/00
Filed: 1991-01-28
Abstract: ABSTRACT      The present invention is directed to an automated poultry processing system having a novel chicken hind quarter cutting stage that does not require the individual chicken hind quarters to be removed from the moving treadmill before or after halving the chicken hind quarters. Each chicken hind quarter is placed into a moveable shackle including a rotatable shackle assembly.  Each rotatable shackle assembly includes a cam plate that, when moved into contact with a stationary cam member, causes the shackle assembly to rotate 90°, thereby rotating the chicken hind quarter by 90°.  The chicken hind quarter then moves into contact with a guide member that positions the chicken hind quarter for subsequent cutting by a rotary saw.  The chicken hind quarter remains in contact with the guide member until the saw has cut the chicken hind quarter into halves, thereby facilitating a precise cut of the chicken hind quarter.  The chicken hind quarter halves, which are still in the moving shackle assemblies, then may proceed to later stages of the poultry processing system.

Title: Imaging lidar system employing multipulse single and multiple gating for single and stacked frames
Inventor: KEELER R NORRIS
IPC: G01S17/89
Filed: 1991-05-16
Abstract: IMAGING LIDAR SYSTEM EMPLOYING MULTIPULSE SINGLE AND MULTIPLE GATING FOR SINGLE AND STACKED FRAMES            Abstract of the Invention:    An imaging lidar system is presented which employs a multipulse multiple gating system which is particularly well suited for underwater imaging.  The imaging lidar system of this invention utilizes a multipulse Q-switched laser operating within the pumping envelope of discharging flash lamps (or other means) to cumulatively illuminate a single frame on a camera (e.g., CCD camera) while the camera is gated repetitively so that each pulse is "observed" at the same depth; that is, the gated camera views that same illuminated area in the ocean.  The sequence is repeated at a frequency which is both the laser pulse repetition rate and the camera frame rate.  The present invention also allows the use of multiple cameras with frame addition or with frames processed separately.  As a result, energy is extracted from the laser in the form of short (1-10 nsec) pulses by rapidly Q-switching during the time the laser is being pumped by the flashlamps.  Provisions are made for subtracting solar noise during daylight, if necessary.  The present invention thus provides a technique for extracting the maximum energy from the laser in the form of these short pulses.

Abstract: A thin film magnetic recording head for high-density recording applications.  The head includes a pole formed from at least two ferromagnetic material layers with one layer having high anisotropy (Hk) and low permeability (µ), and the other layer having low Hk and high µ.  The high Hk layer provides the lower magnetic impedance flux path in the tip region and the low Hk layer provides the lower magnetic impedance path in the yoke region of the head.  A non-magnetic film may be disposed between the layers, with a thickness chosen to minimize domain flux coupling of the two magnetic layers, while allowing magnetic signal flux transfer between layers at an appropriate point between the tip and the yoke. The pole may be sculpted so that the low Hk layer extends only partially into the tip region, or so that the high Hk layer extends only partially into the yoke.  Alternatively, the invention may use a laminated, high permeability layer and a homogeneous layer in place of the high Hk and low Hk layers.

IPC: H04B1/66

Abstract: A system is provided to reduce noise from a signal of speech that is contaminated by noise.   The present system employs an artificial intelligence that is capable of deciding upon the adjustment of a filter subsystem by distinguishing between noise and speech in the spectrum of the incoming signal of speech plus noise.   The system does this by testing the pattern of a power or envelope function of the frequency spectrum of the incoming signal.   The system determines that the fast changing portions of that envelope denote speech whereas the residual is determined to be the frequency distribution of the noise power. This determination is done while examining either the whole spectrum, or frequency bands thereof, regardless of where the maximum of the spectrum lies. In another embodiment of the invention, a feedback loop is incorporated which provides incremental adjustments to the filter by employing a gradient search procedure to attempt to increase certain speech-like features in the system's output. The present system does not require consideration of minima of functions of the incoming signal or pauses in speech. Instead, the present system employs an artificial intelligence system to which is input the envelope pattern of the incoming signal of speech and noise.  The present system then filters out of this envelope signal the rapidly changing variations of the envelope over fixed time windows.
