Abstract: A system for delivery of cardiac implants includes a catheter having a handle assembly including a cable control assembly. The handle assembly further includes a tubular body assembly extending distally from the handle assembly and deflectable by operation of the cable control assembly. The system also includes a robot having a linear displacement platform and a carriage coupled to the linear displacement platform. The carriage includes a drive motor assembly and is at least one of linearly displaceable along the linear displacement platform and rotatable relative to the linear displacement platform. The handle assembly is coupled to the carriage such that the cable control assembly interfaces with the drive motor assembly of the carriage to facilitate operation of the cable control assembly by the robot.

Abstract: Methods of communicating and facilitating secret communication are provided, with the steps of having a first party provide an encryption key to a first client and a decryption key to a second client, having the first client generate a first and second information, both in combination forming the secret communication, first client encrypting the first information with the encryption key and sending the encrypted information to the second client by an independent communication channel such as a third party server, having the first client send the second information to the second client through the first party, having the second client decrypt the encrypted information with the decryption key to recover the first information, and second client combining the first and second information to recover the secret information.

Abstract: A communication device comprising a processor arranged to select a first communication address for sending a first message to a first communication device and selecting a second communication address for sending a second message to the first communication device unless the first communication device has responded to the first message before the second message has been sent.

Abstract: A direct solar steam generator is provided. The direct solar steam generator includes a solar evaporator having an evaporator circuit for circulation of a working fluid, an evaporator inlet pipe for supplying fluid to the evaporator circuit and an evaporator outlet pipe for collecting the working fluid exiting the evaporator circuit, and a solar concentrator for concentrating solar energy towards the evaporator circuit. The direct solar steam generator also includes a fluid arrangement configured to allow forming a static liquid seal in the outlet pipe using the working fluid.

Abstract: A device for converting a rotational movement into a rotatively oscillating movement is described comprising a drive shaft, a second, rotatively oscillating shaft, a driving mechanism, a housing, and a gearing mechanism comprising a movable lever. A sawing device is also described.

Abstract: A device for operation of a surgical or dental drive unit includes a control valve attached to a drive unit to control a flow rate of a compressed fluid flowing from a compressed fluid source to the drive unit. The control valve includes (a) a first control arrangement controlling a rate of flow of the compressed fluid through the control valve; (b) a control switch; and (c) a control sleeve controlled by the control switch to axially move along a longitudinal axis of the drive unit between a first configuration in which the control valve is locked and closed to fluid flow and a second configuration in which the control valve is unlocked and the first control arrangement controls the rate of flow therethrough.

Abstract: A device for controlled operation of a surgical or dental drive unit driven by a compressed fluid source p available in the operating room and comprising A) a control valve attachable to the drive unit for controlling a flow rate of a compressed fluid flowing from a compressed fluid source p to a drive unit; B) a first control means by means of which the control valve is operable; and C) a second control means by means of which a flow rate of compressed fluid may be controlled. The device further comprises D) a control switch which is attached to the control valve and allowing to select between at least three positions (A;B;C): in position A the control valve is locked and closed; in position B the control valve is unlocked and a flow rate of the compressed fluid is controllable by means of the first control means; and in position C the control valve is unlocked and open permitting the control of a flow rate by means of the second control means.

Abstract: A coupling device for connecting tools with different configuration to a driving mechanism. The coupling device may have a longitudinal axis, a first clamping device which may engage a tool with a peg-shaped clamping segment and a second clamping device which may engage a tool with a generally flat portion. The coupling device may be used to connect a tool to a drive shaft which may be attached to a motor. The tools may be locked or unlocked relative to the coupling device by sliding a sleeve along the axis of the coupling device. The sleeve may be biased in a locked position by biasing means such as a spring. The coupling device may be configured so that the first and second tool may be prevented from rotating and/or moving axially with respect to the drive shaft.

Abstract: A bottle manufactured by injection molding techniques for use with liquids which diffuse greatly. The bottle and a cap are of almost continuous double-walled construction. Two concentric walls extend from the container shoulder, wherein an inner container wall is shorter than an outer container wall. The single-walled or double-walled bottom is shaped in such a way that the inner container wall is sealed by contact on the inside and the outside, while the outer container wall is only sealed by interior contact at the bottom.

Abstract: A motion converter comprising a drive head mounted eccentrically onto a drive shaft, and which is eccentrically displaced when the drive shaft rotates. The converter additionally comprises a displaceable transmission element and a displaceable tool holder holding a tool. The transmission element and tool holder are moved to-and-fro when the drive shaft is rotated. The excursion of the to-and-fro motion is adjustable by pivot means, preferably a first pivot pin, displaceably affixed to a housing and connecting the transmission element to the housing.

Abstract: A clamp connection serves to connect two construction components, in particular for an osteo-synthetic fixation device in a structure in which the construction components are off-set from the force axis of the loading force that retains them.
