Abstract: A fault tolerant communication control processor in a time division multiplex communication system is set up with microprocessor units (1-1 ~ 1-n) executing communication control programs, line control units (2-1 ~ 2-n) processing the transferred data for transmission or reception by channel and time slot control units (3-1 ~ 3-n) for assigning the channel addresses to time slots. The time slot control units (3-1 ~ 3-n) are operative to control the information of correspondence between channel addresses and time slots. When either one of time slot control units receives new instructions for channel assignment from a microprocessor unit, it is operative to execute exclusive control by informing the other time slot control units not to use the newly instructed channel.

Abstract: A 1-input/2-output or 2-input/2-output directional coupler type optical device comprising a junction (Co) including two optical waveguides (A,B) arranged parallel to each other and each fitted with an electrode (F₁,F₂ F₃,F₄) for controlling a propagation constant, the incidence end or ends of one or both of the optical waveguides being connected to curved or straight optical waveguides (E), thus forming an incidence-side lead section, and the respective emergence ends of the two optical waveguides being optically connected to curved or straight optical waveguides (D), thus forming an emergence-side lead section. An electrode (F₅,F₆) for suppressing the mode coupling is mounted on each optical waveguide of the emergence- or incidence-side lead section. A high extinction ratio of 30 dB or more can be obtained in either of cross and through modes by activating a required one of the mode coupling suppressing electrodes while applying an electrical signal to each propagation constant control electrode.

Abstract: An output transducer (34) and amplifier (33) are shared between an audio system (25) and a cellular phone (26) in an automotive vehicle. An interface (27) arbitrates between the program audio signals and the phone audio signals to select or deselect each of the audio signals depending on the status of each audio source. When only one source is in use then normally the audio signals from that source are selected. If both sources (25,26) are turned on but a phone call is not in progress, then audio signals from both sources are simultaneously presented to the output transducers after summing. When a call is in progress, only the phone audio signals are selected.

Abstract: In a device for fixing fittings to pipes, having two stop plates movable relative to one another, the invention proposes to provide a spindle drive for the movement of at least one of the stop plates. In this way, a light, inexpensive and operationally reliable construction is created, which can be operated with low handling forces and is operationally reliable since it has no hydraulic or pneumatic lines which may leak. Furthermore, a device of this type is suitable for attaching electric drives, in particular for coupling already existing electric tools, such as a drill or a cordless screwdriver. <IMAGE>

Abstract: In a Local Area Network (LAN) system, an ethernet adapter exchanges data with a host through programmed I/O (PIO) and FIFO buffers. The receive PIO employs a DMA ring buffer backup so incoming packets can be copied directly into host memory when the PIO FIFO buffer is full. The adapter may be programmed to generate early receive interrupts when only a portion of a packet has been received from the network, so as to decrease latency. The adapter may also be programmed to generate a second early interrupt so that the copying of a large packet to the host may overlap reception of the packet end. The adapter to begin packet transmission before the packet is completely transferred from the host to the adapter, which further reduces latency. The minimal latency of the adapter allows it to employ receive and transmit FIFO buffers which are small enough to be contained within RAM internal to an Application Specific Integrated Circuit (ASIC) containing the transceiver, ethernet controller, FIFO control circuitry and the host interface as well.

Inventor: VAN DE PAS HERMANUS ANTONIUS
IPC: H01S5/02315
Filed: 1993-09-17
Abstract: Optoelectronic devices often comprise an optoelectronic semiconductor element such as a diode laser fastened on a carrier. The desired path of a beam of radiation from or to such an element often implies that such an element has to be fastened on the carrier at a certain, for example right angle. As a result, a contact surface of such an element also encloses an angle with another contact surface which lies on the carrier. The provision of a wire connection by means of a wire bonding unit is rendered difficult by this. In the known method, two wire connections and an interposed block are used for solving this problem. 
     A disadvantage of the known method is that it is comparatively laborious and expensive, so that the manufactured devices are also expensive. 
     In a method according to the invention, one of the two contact surfaces is provided with a wire which has a free end, and after fastening of the diode laser or photodiode the free end of the wire is fastened on the other contact surface. One wire connection can suffice and no auxiliary block is necessary with this wire connection method in two steps. Preferably, the wire having the free end is provided on the element. This has various additional advantages such as a less critical fastening of the free end of the wire and the possibility of a reliable intermediate test owing to which the yield of the expensive end product is increased. The invention also relates to an element, preferably fastened on a support body, on which a wire having a free end has been applied.

Abstract: A rack for electronic equipment based on modules of predetermined size comprises a pair of vertical structural members (3) positioned to receive and support card-frames (22) of predetermined dimensions in a vertical array between them and to support cables (32) to be connected to electronic equipment to be mounted in one or more of the said card-frames. The structural members (3) are shaped to define vertically extending cabling spaces (4) which are open and free of fixed obstructions over at least a major part (or major parts) of the height of the cabling spaces
     (a) outwardly to respective sides of the module over at least a major part of its depth ; and   (b) towards the front of the module adjacent to its side.   
     The openings to the sides of the module allow two such racks to be mounted in a conventional side-to-side position, without mounting side panels or partitions between them, so that the adjoining cabling spaces of the two racks come together to create a common cabling space of double width ; in the case of a rack to ETSI dimensions this means a common cabling space wide enough to get a hand in, and in every case it means that cables can if required be positioned along the module boundary. 
     The opening to the front of the module allows cables to be inserted (and removed, if required) from the front of the apparatus, whether or not card-frames and equipment are in place or in service.
