Abstract: In at least one of a plurality of shutter vanes 
forming a shutter there are provided a plurality of 
openings adapted to detect the movement of the shutter 
vanes. A photointerrupter (20) is turned on and off by 
the openings when the shutter vanes move. An output 
voltage of the photointerrupter is compared with a 
reference voltage by a comparator (11). A series com­
bination of a switch (14), which is turned on and off by 
the output voltage of the comparator, and a resistor 
(R2) is connected between the output (PIP) of the pho­

Title: Apparatus for stitcher wire loading
IPC: B27F7/21
Filed: 1989-09-12
Abstract: A replaceable, closed, container cartridge or supply-item 
cassette (21) holds a roll of stitcher wire (22) from 
which U-shaped wire staples are to be formed by operation 
of a stitcher (13). The wire's end is led from the cas­
sette to the stitcher by way of a flexible tube (20) that 
terminates in a coupler/handle member (14) . The cou­
pler/handle member includes a releasable wire clamp that 
is operable to hold the wire's end. The coupler/handle 
member is constructed and arranged to protect the opera­
tor's hands from contact with the wire's sharp, needle-­
like end. When the coupler/handle member is locked or 
coupled to the stitcher, the stitcher's wire feed rollers 
automatically move to a nip-closed position, to entrap the 
end of the wire, and the wire is automatically released 
from the wire clamp. The stitcher's wire feed rollers are 
driven by a stepping motor. The cassette includes a brake 
that is operable to control the orderly feeding of wire by 
the stepping motor.

Title: Bicmos reference network
IPC: G05F3/26
Filed: 1990-01-31
Abstract: A BiCMOS current source reference network which eliminates 
the impact of d.c. power supply voltage drops on the operation of 
ECL circuits is described. This invention is essential for 
implementing ECL design techniques in VLSI BiCMOS circuits. Using 
the current source network, reference voltages are generated 
locally so that the ECL voltage references are correctly 
referenced to the local power supply potentials. A power supply 
insensitive band-gap reference generator is used to generate 
precision on-chip voltage references and current sources. The 
band-gap circuit uses both MOS and bipolar transistors and is much 
simpler than a similar using bipolar-only circuitry.

Title: Multi-media serial line switching adapter for parallel networks and heterogeneous and homologous computer system
IPC: H04L29/06
Filed: 1992-03-05
Abstract: A generic network device includes a serial line switching apparatus for performing either parallel or serial communications amongst multiple nodes over switching networks. An aspect includes is the adaptation of standard and proprietary serial interfaces using either optical or electrical transmission media to interface to the parallel switch. The converted serial data is routed to the selected destination through the parallel switch network, where it is received and converted back into a serial optical or electrical interface/protocol. Thus, the combination of the switching adapter and an ALLNODE parallel switching network make it feasible for serial message data to be switched and routed to various destinations. A a parallel electrical switch can efficiently handle either optical or electrical serial data and utilize information via wireless gateways to provide the features required for parallel processing and "farm" approaches, such as low latency, high bandwidth, scalability, fault tolerance, and high reliability. In addition, further flexibility is provided which permits the switching adapter to be personalized to support the any one of a number of standard and proprietary serial protocols. A personalisation PROM specifies the particular serial protocol that each individual adapter is to support. The parallel switching network becomes a flexible media that interconnects and allows different serial protocols to communicate with each other; i.e., any number of different serial protocols can interface with the same parallel switch network. This allows every node of the parallel system to send and receive messages using its own native protocol. However, a node is not restricted to communicating only with others nodes using the same protocol, but it can communicate with any of the other nodes regardless of the serial protocol they use. The switch enables generic networks with heterogeneous and/or homologous nodes as a computer system. It can replace LANs and WANs and provide high speed cluster switching. Applications include parallel processing with existing computers, and features of multiple processor computer system which transfer multi-media information from one or many senders to one or many receivers, useful in teaching and many other applications. The nodes of an asynchronous computer system are connected asynchronously in a non-blocking by search manner with connections for set up at 2 cycles per cascaded node and message transfer continues at maximum media transfer speed. <IMAGE>

Bremsbeläge aller Räder vergleichmäßigt werden. Dies hat 
den Vorteil, daß jeweils nur ein gemeinsamer Werkstattaufenthalt

Filed: 1992-06-17
Abstract: A display controller includes a digital processor adapted for data communication with a central computer, for controllably downloading alphanumeric data and one or both of image attribute data and complete or partial screen images to be displayed on unmodified standard commercial television receivers. Data memory and program memory are coupled to the digital processor, which stores image formatting data or complete images. Programmable logic circuits are coupled to the data output of the digital processor, and in conjunction with the digital processor convert the attributes presented on the data output of the digital processor into a pixel data field wherein each pixel is encoded to one of a number of available color combinations. A color palette converts the pixel field into RGB data. A video encoder takes the RGB data and modulates a subcarrier signal to provide a composite video output. The display controller is preferably part of a networked gaming system with a central computer system managing entry validation and/or selection or crediting of winning entries in a wagering game having numerous players. Distributed agent terminals in data communication with the central computer system manage input of player data and issue of player entries as point of sale terminals under supervisory control of the central computer. A plurality of standard commercial television receivers are coupled respectively to the video buffers, and simultaneously display the image in conjunction with the respective agent terminals, thereby displaying game data to numerous players at retail locations. <IMAGE>
