Abstract: There are disclosed methods and apparatuses for the assembling of parts using capacitive sensing, both for controlling the closure or "homing" phase of the assembly process and for acquiring one or more of the parts prior to that phase. Assembling of semiconductor parts to essentially two-dimensional and three-dimensional packages, the insertion of a peg in a hole, and an application to tape-automated-bonding (TAB) technology are all described, as are various representations of the resulting capacitive data. Included are the uses of scheduling and optical sensing to supplement capacitive sensing in the methods and apparatuses.

Abstract: This invention relates to coin-operated telephones and apparatus for preventing the accidental or fraudulent simulation of coin deposit signals. At the beginning of each coin call or overtime period, a coding algorithm is randomly chosen at the coin station and the identity of the chosen algorithm is transmitted over the telephone line to a receiving telephone office. For each coin deposited, the coin station generates accumulated coin deposit information, codes it in accordance with the chosen algorithm and then transmits the coded accumulated deposit information to the telephone office. The office decodes the received information in accordance with the chosen algorithm identity information previously received at the telephone office to ascertain the amount deposited at the coin station.

Abstract: A system is disclosed for serving special service calls such as collect, person-to-person and charge-to-third number on a wholly automatic basis without any operator intervention normally being required. The system requests specific information from the calling party such as, his or her name for collect calls, and utilizes the received answers in the formulation of additional announcements to the "called" subscriber. The system is responsive to information received from the called station or third party station for instituting billing for the requested call after a connection is established between the calling and called stations.

Abstract: A system is disclosed for serving coin telephone calls on a wholly automatic basis without any operator intervention normally being required either for notifying the calling party of the required deposits or for monitoring the collection of coins deposited in the coin station. Moreover, coin tone detectors and announcement circuits are isolated so that coin deposits can be detected during announcements.

Abstract: This invention pertains to systems servicing coin operated telephones and, more specifically, to apparatus in such systems for preventing called party fraud in simulating coin deposit signals. During intermediate coin deposit periods, the network connection between the calling and called stations is split into calling and called portions and then these portions are extended and reconnected. A filter is inserted in the extended called station portion to attenuate fraudulent coin deposit signals originating from the called station. A coin tone detector connected to the extended calling station portion is still actuated by valid coin deposit signals from the calling station, but does not detect the attenuated fraudulent signals.

Abstract: A diagnostic and parity generation arrangement is disclosed for use with a pair of duplicated processing units operating in synchronism. A distinct parity generator is associated with the "output bus" of each processor for indicating the parity of the information thereon. When a peripheral address register is loaded, the parity indications generated by the parity generators are compared to ensure that identical information is being applied to the output buses; and when information is written in memory, these same parity indications are combined to generate parity information over the data to be stored and over the address at which the data and the generated parity information are stored. These same parity indications are also utilized during read operations to generate another parity indication which is compared with a retrieved parity indication.

Abstract: An additional concentrator is provided in a Traffic Service Position System (TSPS) similar to that disclosed in A. E. Joel, Jr. Pat. No. 3,731,000, issued May 1, 1973, to facilitate the handling of operator assistance telephone calls requiring routing back to originating offices. More specifically, on the toll office side of this additional concentrator in addition to the normal TSPS remote toll trunks, "loopback" trunks are provided for establishing connections through this concentrator directly back to a plurality of "local" offices served by the concentrator. Operator assistance calls in which only a single digit (normally 0) is dialed are connected to these loopback trunks with the expectation that the call will be completed back to the originating or associated office.

Abstract: A signal detection arrangement is disclosed for detecting signals during variable speed tape movements such as during tape rewinding or fast forward speeds. To elaborate, information encoded as multifrequency information tones is grouped in exercises on a recording tape, and at least two low frequency tones are provided at the beginning of each exercise. Each of these low frequency tones has a frequency which is related to the frequency of a different one of the information tones by a multiple of the ratio of the rewind speed to the normal forward speed times a predetermined factor. Accordingly, during normal playback these low frequency tones will not be detected. However, during fast forward or rewind, each of these tones will be multiplied up to a detectable frequency. Moreover, even over wide variations in these "fast" speeds, at least one of these low frequency tones will be detected.
