Abstract: Described here are systems and methods for accessing Schlemm's canal and for delivering an ocular device or fluid composition therein. The ocular devices may maintain the patency of Schlemm's canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

Abstract: The occurrence of false positives and the post-processing of digital streams subjected to examination by a deterministic finite state machine for character strings are reduced by combining location-based pattern matching, e.g. on packet headers, and content-based pattern matching, e.g. on payloads of packets. One scheme allows automatic transition from a header match state into an initial state of a content matching machine. Another scheme is based on a rules graph defining strings of match states and the examination of a list of match states (rather than characters) which have been previously determined, for example by means of header matching and content matching. The latter is also capable of comparing offset and depth values associated with the match states with offset and depth criteria.

Abstract: A power supply monitoring circuit is provided that utilises an adaptive internal control of the refresh rates of capacitors to reduce the power requirements of the circuit. The circuit provides at an output a signal indicative of the level of the supply voltage relative to a predetermined reference voltage.

Abstract: An intravascular ultrasound catheter may include a central lumen adapted to receive a drive shaft bearing an ultrasound transducer. The intravascular ultrasound catheter may in some instances exhibit improved flexibility. The catheter can include an inner polymeric layer, an outer polymeric layer and a spiral-cut hypotube that is positioned between the inner polymeric layer and the outer polymeric layer.

Abstract: A method of detecting signatures in message segments comprises employing a state machine for the detection of character strings in the message segments. The state machine executes for each input character a transition determined by a current state of the machine and a current input character. The message segments conform to TCP or other ordering transport protocol. The order of arrival of the message segments is monitored. In the event that an intermediate message segment is missing between a processed segment and an immediately subsequent message segment, the current state of said state machine at the end of the said processed segment is stored. The machine is restarted from its null or datum state for the examination of the immediately subsequent message segment, which is then temporarily stored. When the missing segment eventually arrives, it and the stored segment are successively examined for signatures by means of the state machine, beginning at the stored state.

Abstract: A cascade system of network units includes forwarding units which have external ports, a communication fabric connecting the units and at least one processing unit which needs no forwarding database. The processing unit may perform a security operation such as intrusion prevention or encryption. Each forwarding unit on receipt of a packet performs a look-up to determine an egress port, to determine whether the packet must be diverted to a processing unit, to provide the packet with a first forwarding instruction identifying the egress port uniquely within the system and a second forwarding instruction identifying a diversion port by which the packet can reach the processing unit and to set an order field which determines which of the forwarding instructions shall be performed first. The processing unit is operative on receipt of the packet by way of the diversion port to change the order field to specify that the packet should now be sent to the egress port.

Abstract: A content addressable memory stores entries each comprising a rule and as part of the entry a mask identifying all the entities to which the rule is applicable. A search pattern of data and a bit mask identifying the actual entity (or entities) associated with the data is applied as a search word along with a comparison mask that excludes all the other entities from the comparison of the search word with the entry.

Abstract: For each metered flow in a network unit there is a memory entry which defines a time stamp and a rate parameter. When a packet in the respective flow arrives, the time of arrival is compared with the time stamp. If the time of arrival is before the time stamp the packet is discarded. If the packet arrives after the date stamp, it is allowed to proceed and a new time stamp is computed in accordance with the rate parameter. One exemplary computation adds to the time stamp a time interval obtained by dividing the size of the packet by the rate parameter and preferably subtracting from the quotient the time interval between the arrival time and the previous time stamp.

Abstract: A rules engine for the examination of selected fields in an addressed data packet, has an access control list table of which the entries each define an access control list rule, an action and a chain identifier. The access control list rule is a basic rule which refers to a TCP flow. The engine also has an extension rule table of which the entries each define an extension rule, a respective action and a respective rule identifier. The extension rule may refer to a particular flag in a TCP header. When a packet arrives the engine searches both tales. This search is made independently of the usual address lookup. If there is a match in both tables, and the chain identifier matches the extension rule identifier the engine prescribes the action associated with the extension rule. If the chain identifier of a matched access control list rule does not match a rule identifier of a matched extension rule the engine prescribes the action associates with the access control list rule.
