Abstract: A novel game and board or surface is played in combination with two sets of playing pieces consisting of three dice each, one set being visibly distinguishable from the second set and wherein in one embodiment all bets are placed on the board or surface before the first set of dice is throw to speed up the method of play and payoffs for each bet are set by the house. Optionally, the house may set and take additional bets between a throw of the first set of dice and a throw of the second set of dice. In another embodiment of the invention, players use the two sets of dice in sequence wherein winning bets are related to poker hands such as open numbers from 3-35; 3 of a kind; 4 of a kind; 5 of a kind, straight; any 3 pair; 6 of a kind, and six sixes (but specifically excluding two of a kind to provide decisive winning odds for the house) and where the payoffs for each bet are 2 for 1, 3 for 1, 4 for 1, 5 for 1, 8 for 1, 8 for 1, 12 for 1, and 20 for 1, respectively, for example.

Abstract: A test fixture for integrated circuits, particularly those having large numbers of contacts. The fixture has a socket for receiving the integrated circuit, with conductive wad pins of the socket contacting lands or solderballs of the integrated circuit. Four clamping and alignment studs having peripheral grooves near their upper ends extend upward from the four corners of the socket.

Abstract: An attachment for a weight stack type exercise machine to pull the weight stack down while it is being lowered, (or to pull on a weight stack lifting means so as to add to the force applied to the lifting means by the weight stack) so that the eccentric exercise force required to lower the stack is greater than the concentric exercise force required to raise it. Such asymmetric exercise forces more closely match muscle strengths, which are normally greater for eccentric exercise than for concentric exercise. The attachment has an electric motor and a control unit including a keypad, a display and a microcontroller. The motor is coupled to the weight stack by an eccentric force control cable or a toothed belt or alternatively is operatively connected so as to apply additional force to the lifting arrangement. The keypad allows the user to select the amount of force added during the eccentric phase of exercise, when the weight stack is moving down.
