Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for determing when a gripper or hand resiliently mounted on a robot arm by a set of compliant springs, strikes or makes contact with an object that impedes or limits hand movement. The apparatus includes a light source, preferably mounted in a particular loca-tion on the robot arm hand and a light sensitive device cooperatively mounted in a particular location on the robot arm body, a device that is capable of continuously genera-ting hand-to-robot arm body relative position signals in response to the position of optically focused light from the light source impinging on the light sensitive device. Relative movement between the robot arm body and the robot hand normally resulting from contact between a motion impeding object and the robot hand causes the light sensi-tive device to generate a signal indicative of such object contact and/or extend of relative hand-to-robot arm body movement.  This signal may be employed, for example, either to terminate movement of the arm or to cause a particular force to be applied to the object contacted by the robot hand.

Abstract: ABSTRACT       A computer based telephone accounting system collects data on calls made from a key system or PBX and automatically generates accounting reports which include the costs of the calls. A minimum amount of memory is used in calculating the costs by grouping combinations of area codes and exchange numbers into geographic bands and recomputing the distance from a particular area code and exchange number to all the remaining combinations of area codes and exchange numbers in the other bands. The combinations of area codes and exchange numbers are stored in an N x M memory matrix where N equals the area code numbers and M equals the exchange numbers. A plurality of memory stored, multi-bit data words defining an algorithm for computing the cost of a call to a particular band are individually selected using an address defined by the position of the bit in the memory matrix which corresponds to the particular area code/exchange number being called. A programmed computer calculates the cost of a call using a memory stored rate table and the selected algorithm.
