Abstract: An electrical connector device for multiple diverse electrical connectors is provided according to embodiments of the invention. The electrical connector device includes two female connectors in the same housing. The two female connectors are of different types and are oriented orthogonal to each other. The electrical connector device has a front face in which the openings to the two female connectors are located. The front face occupies the same space as another larger, standard electrical connector, thus allowing the electrical connector device to accommodate two separate connectors in the same space as a single standard connector, and thereby provide selective, simultaneous, independent, and dual functionality.

Abstract: A circuit for interconnecting electrical components in a stacked arrangement through the use of connector elements. The connector element can include a connector body having an internal ground plane, and signal lines disposed on the surface at the connector body. The connector element fits into receiving slots located on each of two network hubs.

Abstract: A circuit for interconnecting electrical components in a stacked arrangement by the use of connector elements in which a substantially continuous bus is formed by the connector elements and the components to conduct signals between the components in the arrangement. The circuit and arrangement include identifier circuitry for automatically assigning an identifier to each electrical component in the stack and terminating circuitry for selectively establishing terminating connections between a terminal electrical component of the stack and the substantially continuous signal bus. The identifier circuitry and the terminating circuitry can be implemented by programmable array logic located in each electrical component.

Abstract: A circuit for interconnecting electrical components in a stacked arrangement through the use of connector elements. The circuit includes reset circuitry for automatically resetting the power-up sequence of the electrical components in the stack to allow the components to be powered up in any desired sequence. The circuit can also include identification circuitry for generating a unique identifier for each component in the stack and termination circuitry for selectively establishing terminal connections between the first and last components in the stack.

Abstract: A connector element and electronic component arrangement in which the connector element cooperates with receiving slots provided in first and second electronic components to electrically connect the components. The connector element includes ground traces and signal traces which are brought into electrical contact with signal leads and ground leads of the electronic components when the connector element is inserted into the receiving slots located in the first and second electronic components. Multiple electrical components may be electrically connected in a stack using multiple connector elements which cooperate to form a substantially continuous bus. The connector element and electronic component arrangement eliminates the signal delay, signal reflection, and interference associated with data cables.

Abstract: A multi-speed, full duplex modem is disclosed for transmitting and receiving analog signals over a telephone network in communication with a remote modem. The analog signals are converted to digital data for processing by a signal processor and a microcomputer. A bi-directional bus is disposed between the signal processor and the microcomputer for selectively transferring multiple bits of data in either a transmit or receive direction. One or more of the multiple bits of data are restricted to convey bus direction data in one of the transmit and receive directions, and not restricted in the other direction. The full duplex modem allows simultaneous transmission and reception of analog signals over the telephone network, at one of the multispeed data rates selected for compatability between the full duplex, multispeed modem and the remote modem.

Abstract: A dual speed, full duplex modem for transmitting and receiving data on a dialed-access telephone line includes a signal processor for storing samples corresponding to a sinusoidal waveform, for selecting samples at intervals determined by the mode in which the modem is operating to synthesize a signal for modulating by data for transmission, and for autocorrelating a received signal at a frequency determined by the mode in which the modem is operating to recover data from the received signal. The signal processor includes configuring input ports, and a microcomputer receives instructions related to the mode in which the modem is to operate to output a mode-configuring word to the configuring inputs. Conversion from the signal processor's digital output to the analog signal to the line and from the line's analog signal to the signal processor's digital input take place through two time-division multiplexed coder-decoders. The stored sinusoid is mu-law compressed.

Abstract: A digitally coded electrical supply system is provided for the selective control, through a plurality of code transmission conductors, of electrical power through a single power bus to a large plurality of electrical loads. The system includes a number generator for sequentially and cyclically producing digitally coded numbers into a plurality of code transmission conductors, a plurality of load decoders, a plurality of power switches, a power bus and a plurality of electrical loads. The system also includes a plurality of switch decoders, and a plurality of electrical switches, each switch connecting one of the switch decoders to one of the load decoders through a common activator conductor. In operation, the closing of any of the electrical switches is effective, in cooperation with the connected one of the switch decoders and the common activator cable, to activate an associated one of the load decoders and to supply electrical power to the associated one of the electrical loads.
