Abstract: An exercise apparatus includes a frame and handles mounted on the frame and moveable by a user in opposite directions. The handles are coupled to a transmission so that movement of the handles by a user create rotational movement of a transmission input, movement of the handles in one direction creating rotational movement of the transmission input in one direction and movement of the handles in the opposite direction creating rotational movement of the transmission input in the opposite direction. The transmission couples the transmission input to a resistance means, such as an eddy current resistance device, in a manner to provide a different resistance to rotation of the transmission input depending upon the direction of rotation of the transmission input. Thus, the resistance to rotational movement of the transmission input in one rotational direction is greater than it is in the opposite rotational direction.

Abstract: A protective holder for storing and displaying articles, such as photographs, baseball cards, game cards, and the like. The holder is formed from a front sheet that is welded to a back sheet to form a plurality of pockets. Cuts are made in the back sheet to create flaps with tabs that facilitate lifting of the flap for insertion and removal of articles in a manner that minimizes contact damage between the articles and the holder. The flaps are coplanar with the back sheet at all times to prevent indentation of the stored articles when pressure is applied to the flaps. This also enables insertion of entire holder into a thicker, stiffer sheath for further protection, if desired, without the problem of objects dislodging and falling out in the thicker, stiffer sheath.

Abstract: 1. A system for detecting the movement of a remote object comprising trantting means for illuminating said remote object with a signal of wave energy, receiving means for recovering an echo reflected by said object, signal display means responsive to said echo to provide a separate visual display of each cycle of said reflected echo, and frequency comparing means responsive to a difference in frequency between the wave energy of said received echo and the wave energy of said transmitted signal to vary the orientation of said visual indication from a reference orientation, whereby a variation in said orientation will provide an instantaneous indication of a doppler effect on said transmitted wave energy.
