Articulated bus having a two-axle leading car and a single-axle trailing car. The leading car has a driving axle which is driven alternatively by an internal-combustion engine arranged in the trailing car and an electric motor arranged in the leading car.

A device for making a 16-bit data bus microprocessor compatible with peripherals, expansion devices and associated software designed for an 8-bit data bus. The 16-bit data bus is divided into high and low portions, the low portion of which is coupled to the 8-bit data bus by a buffer which is disabled or enabled. The high portion is selectively coupled to the 8-bit data bus when a high data byte is to be transferred either during 8-bit byte operation or in word operations. The device may be bypa...

A bus interface for interfacing between a processor and a shared bus is disclosed. The bus interface allows the exchange of data in the form of packets between the bus and the processor. An interface control device exchanges control data with the shared bus (e.g. identification signals, polling signals, control signals) in order to regulate accesses of the interface circuit to the shared bus. State machines (e.g. a transmitter and a receiver) including data pipelines, are responsive to control s...

A system for reducing a fixed number of data buses and connections in a computer system having a number of modules connected to the data bus utilizing the internal circuits of the various processing units or modules to transmit data from one unit to another via the data bus when the normal function of a unit can be interrupted, with the data routing and module control being under the control of a command bus.

A self-propelled bus-type vehicular structure for use as a mobile restaurant. The vehicle has separately defined portions for food preparation and food service and consumption. The vehicle provides a restaurant facility during ground transit to simultaneously combine the functions of eating with those of sight-seeing. The restaurant furniture relating to both food service and consumption is particularly configured for use in a vehicular structure and particularly adapted for use during transit o...

A miniaturized plastic bus bar connecting a series of spaced terminal pins arranged in a row. The bar has U-shaped cross-section or the like with parallel legs and a connecting base web; and the web has openings formed by slots removing the bar base in the area of each pin. When one metal bar is used, the opposite leg can have a longitudinally extending boss to contact the pins and the opposite leg can be divided between each opening to localize the resilient force of the plastic material in gri...

A bus system is disclosed in which stations having a message to send request access to a parallel bus and an arbitrator responding to the requests connects the transmitters of the stations to the bus in sequence. The words of a message placed on the bus respectively represent the address of the station to which the message is to be delivered, the address of the sending station, and data. A station asserts a signal on one control line in response to its address being on the bus and asserts a sign...

A data signal appearing at an input node of a bus transceiver is transmitted to an output node thereof during a clock cycle. During a second phase of the clock cycle, the data signal is captured in a latch of the transceiver and continues to be transmitted to the output node. Additionally, a receiver is enabled to the detect the transmitted data signal at the output node and to transmit the detected data signal to the input node. Thereafter, the detected data signal can be sensed by an external ...

An optical bus for distributing a light wave signal to a plurality of receivers. The optical bus (10) includes a generally cylindrical form (12) having a helical groove (14) inscribed on its outer surface. At a plurality of nodes (30), an optical fiber (16) wound about the form within the helical groove is caused to bend through a radius of curvature (22) sufficiently small so that a portion of the light propagating along the fiber is transmitted outside the fiber. A plurality of light detectors...

A bus station and a bus system in which two bus stations are connected by at least one bus conductor. Messages are transmitted via a current flowing over the bus conductor. The bus station is supplied with operating current over the bus conductor. For this purpose, an energy storage device stores operating energy. In order to transmit messages, the bus station closes the switch and thus generates a current flow, which discharges the energy storage device of the bus station via the switch and res...
