Abstract: A water jet surgical device comprises a fluid feed device, which is controllable by control signals from a control device, for delivering a fluid into a connecting line of a surgical instrument with an outlet nozzle. The fluid feed device includes at least one measuring device, which is configured such that following the connection of the surgical instrument to the fluid feed device, the measuring device generates measuring signals to represent a quantity of fluid delivered. The quantity of fluid delivered may be displayed on a display or recorded in a recording unit. This enables improved monitoring of surgical operations.

Abstract: An interface includes three sub-interfaces. A first and second sub-interface receive first/second inbound IQ data streams, respectively, packetize the first/second inbound IQ data streams to obtain first/second inbound IQ data packets, respectively, and transmit the first/second inbound IQ data packets to the baseband processor via a first/second set of RX lanes, respectively. Each first/second inbound IQ data packet comprises a data packet identifier out of a common set of possible data packet identifiers. A third sub-interface receives outbound IQ data packets from the baseband processor via a TX lane, and depacketizes the outbound IQ data packets to obtain an outbound IQ data stream. The third sub-interface receives an RX not-acknowledge signal via the TX lane that identifies a defective first or second inbound IQ data packet within the first/second inbound IQ data packets.

Abstract: A method is described for driving matrix displays which are made up of a plurality of lines with individual pixels, which lines are configured as rows and columns, wherein individual lines are driven selectively by rows being activated for a defined row addressing time and an operating current or a corresponding voltage being applied to the columns in correlation with the activated row corresponding to the desired brightness in the pixels. In order to improve the performance of the display, the row addressing time for each row is determined as a function of the maximum brightness of all the columns of the row.

Abstract: A medical pump for use in water jet surgery which provides ease of connection between a pump unit and a pump actuating device. The medical pump includes a pump unit and a pump actuating device. The pump unit has at least one piston. The pump actuating device includes a holding device and at least one coupling device, the combination of which is configured to connect the pump unit and pistons to the pump actuating device. The pump actuating device includes a drive device controlled by a control system to actuate the pump unit, to open/close the holding device, and to open/close the at least one coupling device. The pump actuating device includes a detection device in communication with the control system that detects a relative position between the pump unit and the pump actuating device and transmits detection signals to the control system.

Abstract: A modular base assembly for a rotary drill head includes a drive flange assembly having a tubular drive shaft configured to engage at least a lower drive interface. The modular base assembly also includes a gear housing supporting the drive flange assembly. Furthermore, the modular base assembly can also include a plurality of interchangeable gear pinions selectively coupled to the drive flange assembly.

Abstract: A method and apparatus for the removal of free, emulsified, or dissolved water from liquids of low volatility, such as oil, is shown. The liquid of low volatility is removed by contacting the fluid stream of concern with one side of a semi-permeable membrane. The membrane divides a separation chamber into a feed side into which the stream of fluid is fed, and a permeate side from which the water is removed. The permeate side of the chamber is maintained at a low partial pressure of water through presence of vacuum, or by use of a sweep gas.
