Patent EP-0296427-A1 (EP)
Inventor: DOMER JOSEF DIPL-ING
IPC: B23K26/70
Filed: 1988-06-10
Abstract: In order to protect against a hazard to personnel in the event of fracture of optical fibres carrying laser light, a laser safety switch is normally provided which is controlled by the opposite direction of the transmission path and, in the absence of a signal in the opposite direction, also switches the laser off in the transmission direction. In the case of directional operation there is no return channel. For this case, it is proposed that a monitoring photodiode be optically coupled to the pigtail of the laser diode, via an optical junction. The output current from the monitoring photodiode is compared with a reference current and, if the light power exceeds a predetermined limit, a controlled switch is operated and hence interrupts the supply currents for the laser diode. <IMAGE>

Abstract: There is disclosed herein a data link controller (530) and an interface specification for a generic class of network interface modems (78), one of which is disclosed herein for a client data processing unit for use in a data communications network. The specific modem (78) described herein is for use in a broadband local area data network with collision avoidance protocol. The data link controller (530) features hardware acknowledge circuitry (Fig. 19) that acknowledges the receipt of a perfect data packet immediately upon receipt thereof without request to or assistance by the client data processing unit. The DLC (530) prepares the acknowledgment packet from the incoming data packet and places it on the data link without going through a line acquisition protocol. Each received acknowledgment packet is placed in a transmit buffer (571) at a known location relative to the data packet which was just transmitted, for which it is an acknowledgment so that each acknowledgment packet may be located in less time by the client data processing unit. The acknowledgment packets are logically part of the transmit process and are therefore placed in the transmit buffer.

Abstract: The bandage for maintaining the anterior chamber of an eye according to the present invention is formed so as to cover an incision during operation and to tightly contact with the incision and its circumference, has a small hole for insertion of instruments for operation and is transparent. This bandage can prevent the outflow of aqueous humor through an incision during ocular operation without conducting the temporary suture of incision and thereby enables ocular operation in a state where the anterior chamber is maintained. Therefore, the bandage has solved various problems (e.g. complicated operation procedure, long operation time, high invasion associated with operation) encountered in the conventional ocular operation wherein the incision is temporarily sutured to prevent the outflow of aqueous humor therethrough and thereby to maintain the anterior chamber.
