Inventor: WONG WAYNE S
IPC: A61F9/007
Filed: 2012-08-30
Abstract: The invention relates to systems and methods for controlling vacuum within phacoemulsification systems. The phacoemulsification system may include a handpiece having a needle. The needle is coupled to a power source configured to cause the needle to be ultrasonically vibrated during operation and an aspiration source. The system further includes a footpedal that defines a first position and a second position. The system also includes a computer program product operatively coupled to the handpiece and the footpedal, the computer program product having a computer-usable medium having a sequence of instructions which, when executed by a processor, causes said processor to execute a process that controls power from the power source and vacuum from the aspiration source applied to the handpiece. The process includes the steps of providing a vacuum at a first level to the handpiece when the footpedal is at the first position; providing power to the handpiece when the footpedal is at the second position; and reducing the vacuum to a second level when the footpedal transitions from the first position to the second position.

Abstract: A method for operating a control network includes a first control computer, a second redundant control computer and a plurality of data-processing appliances, wherein a connection between the computers and the appliances is provided by a redundant and diverse heartbeat. The connection between the computers is checked before operating the control network. If a test result is positive, a master function is assigned to the first computer. If the test result is negative, both computers connect the appliances to themselves in a defined sequence.  When a predetermined number of appliances are connected to the first computer, the computer takes over a master function and the second computer takes over a standby function, or, when a number, which is less than the predetermined number, of appliances are connected to each of the two computers, a signal is produced which signals a fault state of the control network.

Abstract: A hydrodynamic axial bearing for the mounting of a shaft (40) which is mounted rotatably in a bearing housing (20), comprising an axial stop (21) of the bearing housing and a bearing collar (10) rotating with the shaft. A lubricating gap (52) which is delimited by a profiled circular ring surface (31) and a sliding surface (11) and is acted upon by lubricating oil is formed between the axial stop (21) and the bearing collar (10). The profiled circular ring surface (31) and the sliding surface (11) are formed in such a manner that the lubricating gap (52) tapers radially outwards with respect to the axial direction. As a result, temperature deformations occurring during operation and deformation because of centrifugal forces, shearing forces and other forces in the bearing collar can be compensated for.

Abstract: A system for ring suppression facilitates notification and handling of unwanted calls as desired by a recipient, and in particular without disturbing the recipient. A new social dimension of call presentation logic is now available to callers. A telephony device is configured to receive an incoming call. The incoming call includes a calling line identity (CLI). On the telephony device, individual contacts in an address book are searched for a match to the CLI. If a match is found, a first phone action is activated (such as ringing the phone). If a match is not found in the address book for the incoming CLI, a second phone action is activated (such as not ringing the phone, and displaying the CLI). In other words, a call that is not in the address book of the recipient (B party) is silenced.

Abstract: A fluid-driven motor has a manifold with an arcuate seal including first and second valve openings and a sealing surface. A cylinder pivotally mounted on the manifold has a facing surface cooperating with the arcuate seal. The arcuate seal and the facing surface define a position-responsive valve configuration such that, when the cylinder assumes a neutral position, an aperture of the facing surface faces the sealing surface, and when the cylinder is angularly displaced in either direction, the aperture overlaps one or other of the valve openings, thereby connecting to the correspond fluid flow channel in the manifold. A pressure compensation volume underlies the sealing surface and receives fluid pressure from the fluid flow channels through valves, or from the internal volume of the cylinder, so that a pressure within the pressure compensation volume approaches a value no less than a current pressure within the internal volume.
