US Patent:

47035412, Nov 3, 1987

Filed:

May 14, 1986

Appl. No.:

6/863104

Inventors:

Peter R. Howard - Dorchester MA
Mance Ekas - Norwell MA
Frank J. Rizzo - Everett MA

International Classification:

A22C 2902

US Classification:

17 71

Abstract:

An automated, self-contained apparatus for extracting meat from the appendages of crustaceans, such as crabs, the appendages having been severed from the body and cooked. The device includes a plurality of stations which recover and collect the meat in the appendages as well as dispose of the empty shell. The appendages are placed in radially extending recesses of a circular motor driven platter, the platter being used to transport the appendages from station to station. The appendages pass through a cutting station which removes the end of each appendage so that there is an opening large enough to allow the meat to be expelled and recovered when pressurized air is injected into the appendage at the next station, the meat extracting station. Pressurized air is also utilized at the third station, the shell ejectment station, to remove the empty shells from the platter.

Pressurized air is also utilized at a second station to blow the appendage into its preferred position in its recess, and at the fourth station, the shell ejectment station, to remove the empty shells from the platter.

International Classification:

F42B 1328

US Classification:

244 31

Abstract:

A method for steering solid propellant ballistic vehicles during powered flight which eliminates the requirement for cutoff control by allowing simultaneous fuel depletion and velocity-to-be-gained, V. sub. G, nulling. The vehicle booster is steered along a velocity trajectory of length equal to the remaining velocity capability, V. sub. CAP, which results in a fuel-inefficient trajectory. The trajectory is divided basically into three phases--an exit phase, a fuel-depletion guidance (FDG) phase and a short phase of constant attitude thrusting just prior to final stage burnout. For the exit phase the launch azimuth and the pitch-over magnitude can be varied from their usual fuel-efficient values. During fuel-depletion guidance the additional degree of freedom is the angle,. theta. , between V. sub.

Abstract:

A robot control system determines which of a number of discretizations to use to generate discretized representations of robot swept volumes and to generate discretized representations of the environment in which the robot will operate. Obstacle voxels (or boxes) representing the environment and obstacles therein are streamed into the processor and stored in on-chip environment memory. At runtime, the robot control system may dynamically switch between multiple motion planning graphs stored in off-chip or on-chip memory. The dynamically switching between multiple motion planning graphs at runtime enables the robot to perform motion planning at a relatively low cost as characteristics of the robot itself change. Various aspects of such robot motion planning are implemented in particular systems and methods that facilitate motion planning of the robot for various environments and tasks.
