Abstract: A manual forklift for lifting, maneuvering, and arranging palleted freight, comprising an extensible wheeled base, a steering handle, a mast, and a boom with a descending standard secured to a support frame carriage and forward extending tines. Hydraulic jack cylinders joining the mast to the boom and the boom to the descending standard in concert with hinge joints connecting the mast to the boom and the boom to the descending standard allow the tines to be manipulated forwardly or backwardly, raised or lowered, and tilted upwardly or downwardly relative to the mast and base, enabling the user to transfer palleted freight engaged by the tines between surfaces with differing heights and angles and across longitudinal spaces. Castered wheels affixed to the base further enable freight to be moved multi-directionally, including laterally leftward or rightward.

Abstract: A system and method for determining if a received email is human or machine generated. Each received email is stored temporarily after the sender's address is extracted. A record from a database of challenges is randomly selected. Each record in the database is an image of a commonly known object. Associated with each object is an easily answered question about the object. The answer to the question about the object is also stored with the question. Next a set of image transformations is randomly selected and applied to the randomly retrieved image. The transformed image is sent to the email sender with the challenge (question about the object in the image.) The challenge question is constructed so that answering the challenge is beyond the capabilities of current computing technology. The email is queued until a response to the challenge is received from the sender. When received, the answer provided by the sender is extracted and compared to the answer stored with the randomly retrieved image.
