Abstract: A system for performing ophthalmic surgery includes a robotic positioning system including an end effector. The robotic positioning system is configured to position the end effector with at least five degrees of freedom. An ophthalmic surgical instrument is mounted to the end effector along with an accessory device configured to facilitate performance of an ophthalmic treatment by the ophthalmic surgical instrument. The robotic positioning system may be controlled to enforce anatomical boundaries and implement predefined motion profiles.

Abstract: A system for performing ophthalmic treatments includes a handpiece configured to be held by a hand of a surgeon. An end effector is mounted to the handpiece and configured to manipulate tissue of a patient, such tissues of the eye when performing an ophthalmic treatment. The system includes a motion sensor configured to sense movement of the handpiece and one or more stabilizing actuators configured to stabilize movement of the handpiece in response to movement of the hand of the surgeon. A controller is coupled to the motion sensor and the one or more stabilizing actuators and is configured to instruct the one or more stabilizing actuators to compensate for motion detected by the motion sensor. The controller may include a high-pass filer with the output of the high-pass filter used to control the stabilizing actuators. The parameters of the high pass filter may be adjusted throughout an ophthalmic treatment.

Abstract: An arrangement for manipulating a medical device is inserted into the body of a patient. There is a drive element to be driven by a motor. There is also a control element for controlling at least one motion of the medical device. A transmission arrangement transmits motion from the drive element to the control element, the transmission arrangement having first and second members which are frictionally engaged with one another so that motion may be transmitted from one to the other. There is a manual manipulation control, which may be grasped by a user to move the medical device manually while the first and second members remain in frictional engagement with one another.

Abstract: A lifting element for use with a transfer trolley, the element comprising: a support member having a support surface and a sheath attached to the support member such that, in an initial configuration, a first portion of the support surface is covered by the sheath and a second portion thereof is uncovered, wherein the sheath is operable to be inflated so as to cause the sheath to extend and evert, insinuating itself under a load in order to support the load, and, after inflation, the support member and the sheath may be moved with respect to each other so that the support member extends further into the sheath, the second portion of the support surface is covered by the sheath and the support surface at least partially supports the load.

Abstract: A surgical apparatus comprising: a base unit; an arm coupled to the base unit, the arm comprising a first section and a second section which are moveable with respect to each other about a joint, the arm being configured to receive a guide-tube; a tracking un it coupled to the joint and configured to track movement of the first section of the arm with respect to the second section of the arm; and a processor configured to: receive intra-operative image data relating to the guide-tube and the anatomy of a patient from which an initial position and orientation of the guide-tube relative to the anatomy of the patient can be determined, the image data including image data relating to a target location within the patient, receive tracking information from the tracking unit, and track the position and orientation of the guide-tube based on the initial position and orientation and the tracking information such that the guide-tube may be aligned with respect to the target location within the patient using the tracked

Abstract: A system for assisting in work carried out on a workpiece and having a frame of reference. The system includes a referencing arrangement to register the position of a first location in the frame of reference of the system; a tool holder for holding a tool to assist with the work; a data interface to receive image data relating to the workpiece; and a processing arrangement to register the image data within the frame of reference of the system. The position of the tool holder is known within the frame of reference of the system. The image data represents an image which is indexed by position relative to the first location. The processing arrangement utilizes the relative position of the image represented by the image data with respect to the first location and the position of the first location in the frame of reference of the system.

Abstract: A container is formed of a shell having a top section, a bottom section and a central section connecting the top section and the bottom section. At least a majority region of the central section is provided with a plurality of structural ribs about its periphery. The ribs are discontinuous in a circumferential direction extending around the central section and have specific structures in their shape, their orientation with respect to each other and their longitudinal alignment to enable the container to withstand deformation due to internal or external pressures. Each rib has longitudinal angle of orientation is less than 90° relative to the vertical axis of the container.

Abstract: A fountain-style carbonated soft drink dispenser includes a housing adapted to attach to a beverage container, an actuator for selectively opening a fluid conduit, and one or more long tubes that vary a pressure drop across the dispensing assembly and convey fluid. The resistance through the tube(s) is decreased as the pressure within the container decreases so as to maintain a substantially constant flow rate throughout dispensing.

Abstract: A dispenser assembly that can be used as a dispenser on a container includes a dispenser body having a flow passage, and a porous flow control member positioned in the flow passage such that the liquid must pass through at least a portion of the porous flow control member before being dispensed. The porous flow control member is operable to vary a resistance to flow of the liquid through the dispenser assembly during dispensing. A valve is provided and is movable between an open position that allows the liquid to be dispensed and a closed position that prevents the liquid from being dispensed. A discharge spout directs the flow of liquid discharged from the container. A dip tube is attached to the dispenser body and extends inside the container to supply the liquid to be discharged to the dispenser body. An attachment portion is provided to attach the dispenser assembly to the container.

Abstract: A dispenser includes a dispenser body which defines a flow passage, a valve assembly, and an actuator. The valve assembly is disposed in the flow passage and includes a first valve member and a second valve member. An actuator is coupled to the valve assembly. When the actuator is manipulated through a first range of motion, only the first of the two valve members is displaced, and when the actuator is manipulated through a second range of motion, both the first and second valve members are displaced in unison.

Abstract: A transfer trolley, to lift loads but particularly adapted to pick up a patient from a bet using a plurality of horizontally extending tines. Each tine consists of a tube having one end fixed in a position and a free open end. A sleeve surrounds the tube and is withdrawn into the interior of the tubes. The tines are then located next to a patient and a fluid under pressure is inserted into the sleeve, causing the sleeve to emerge from the end of the tube and to insinuate itself under the patient lifting the patient in the process. As the patient is lifted the trolley is moved to place the tube under the patient and to provide support while the patient is moved. The trolley can be adapted to move patients from beds or chairs.

Abstract: An apparatus for transmitting acoustic ultrasonic pulses and for receiving "echos" of the transmitted pulses, comprises a housing, an upstanding wall mounted on the housing defining the mouth of a well, and a transducer mounted in the housing so that the operative part of the transducer is located in the well. The well is substantially watertight and is provided with a jet for introducing water or other fluids to the well, or is pre-filled with fluid.
