Abstract: A system for controlling a computer by thoughts in the user's brain. The system applies stimuli of the brain via magnetic source imaging (MSI) for controlling the computer. Patterns of brain stimuli are recorded along with the particular thoughts that produced them and these thoughts are interpreted as functions for controlling the computer in much the same way as inputs from a keyboard or mouse. Criteria of acceptance of thought stimuli are generated by the system. Body stimuli, in addition to the brain stimuli, are monitored and used by the system. A user profile is maintained and displayed along with selected pictures for assisting with stimuli/thought pattern utilization. Artificial intelligence is used to enhance stimuli selection, human factors and reliability, as well as analyzing past errors, adverse occurrences and performance.

Abstract: Repetitive data and non-repetitive data, including periods of no information, is encoded prior to transmission or storage in digital form to minimize the memory space required for storage or the time required to transmission. Repetition, partial repetition, and near repetition is encoded in a form indicating the occurrence of repetition, its characteristics and its duration. The existence and size of repeated patterns in the data is dynamically determined. When repetition is detected, non-repetitive data is inserted into the data stream and repeated data is removed from the data stream. To this non-repeated data in the data stream are added a coded repeated pattern sample, an identification preamble signal, an instruction signal for decoding purposes, a period count signal, a mask signal, and a repeat count signal. All necessary data elements are combined and assembled to produce compressed data. A receiver utilizes these coded and uncoded data elements to regenerate complete original data.

Abstract: Apparatus and methods are provided to connect a call between two parties located at different time zones having different calling costs. The calling costs, which relate to tariffed calling rates, are compared to determine which location has the more economical cost of placing the call. The call is then originated from the location having the lower cost.

Abstract: Digital information is encoded prior to storage for minimizing the space required for storage of the digital information. The data is compared with prior received data such as to detect repetition. When repetition is detected, a code indication of the period of repetition and the duration of repetition is inserted in the stored data. Information is restored utilizing decoding networks responsive to the inserted codes which cause reinsertion of the repetitions.

Abstract: Analog or digital information, for example an audio input, is converted to a digital representation and encoded prior to storage in a digital form for minimizing the space required for storage of the digital information. Pauses are eliminated and encoded in a form indicating the occurrence of the pauses. Data is compared with prior received data such as to detect repetition. When repetition is detected, a code indication of the period of repetition and the duration of repetition is inserted in the stored data. Information is restored utilizing decoding networks responsive to the inserted codes which cause reinsertion of the pauses and repetitions. Also, when the information is restored, background audio may be provided in the silent periods either from a separate memory or, when available, from an audio input circuit.

Abstract: Gross, U.S. Pat. No. 3,842,350, teaches satellite communication system in which subscribers are connected to each other by appropriate assignment of two different transmitting frequencies to two parties, each being assigned a receiving frequency matching other's transmitting frequency. When third party (in commonest case, operator) must communicate with both subscribers, prior art requires operator to have as a minimum two receivers whose outputs are mixed to operator headset and two transmitters fed from operator microphone. One pair of operator transmitter and receiver communicates with one subscriber, the other pair communicates with other subscriber; but subscribers can not communicate with each other. This is somewhat inconvenient for operator intervention and, of course, intolerable if a conference connection is required.
