Abstract: A camera reading apparatus having an alignment guide is presented. The alignment guide may have a rigid platform having a substantially flat bottom surface, a substantially flat top surface that is parallel to the bottom surface, and an aperture through the top surface and the bottom surface. The bottom surface may have a first portion and may have a second portion that forms a ledge projecting from the first portion. The first portion may have a front edge, and the second portion may have a side edge. The front edge and the side edge may intersect to form a right angle.

Abstract: A flow processing facility, which uses a set of artificial neurons for pattern recognition, such as a self-organizing map, in order to provide security and protection to a computer or computer system supports unified threat management based at least in part on patterns relevant to a variety of types of threats that relate to computer systems, including computer networks. Flow processing for switching, security, and other network applications, including a facility that processes a data flow to address patterns relevant to a variety of conditions are directed at internal network security, virtualization, and web connection security. A flow processing facility for inspecting payloads of network traffic packets detects security threats and intrusions across accessible layers of the IP-stack by applying content matching and behavioral anomaly detection techniques based on regular expression matching and self-organizing maps.

Abstract: A method, apparatus and article of manufacture for discarding a data packet. The data packet is classified according to a type of service (TOS) indicator and modified with an internal service class (ISC) indicator according to the TOS indicator. The data packet is modified with a watermark (WM) indicator according to the availability of a system resource. The ISC, WM and a drop preference (DP) indicator of the data packet are compared to a committed information rate (CIR). The packet is discarded if the DP exceeds the CIR.

Abstract: A method, apparatus and article of manufacture for routing a data packet in a fault tolerant manner. A data packet is received from an incoming data channel and is transferred to a switching engine (SE) through an access processor engine (APE). A route for the data packet is generated using a central processor resource (CPR). The data packet is transferred from the SE to an outgoing trunk physical module (TP) using the route.

Abstract: A method, apparatus and article of manufacture for enabling flexible egress traffic queuing. A queue selection word is generated and a data queue is monitored for data. An output mask word is generated associating the data queue to an output channel and a priority value if the data queue contains data. The output channel is processed according to the queue selection word and the output mask word.

Abstract: The present invention provides a system and method to implement a packet switch buffer for unicast and multicast data. Incoming data packets are first stored in an input buffer memory. These data packets are examined to determine where in a primary output memory to place the data packets. The data packets are then transferred from the input buffer memory to the primary output memory. Afterward, the data packets are transferred from the primary output memory to a secondary output memory, and then from the secondary output memory to line card interface units (LCIUs).

Abstract: The present invention provides a system and method to implement a packet switch buffer. Incoming data packets are temporarily stored in an input buffer memory. Data packets in the input buffer memory are then examined to determine locations in an output buffer memory where the data packets should be transferred. Data packets in the input buffer memory are then transferred to the output buffer memory, such that data packets destined for a line card are written in an output memory block corresponding to the line card. Afterward, data packets in the output buffer memory are extracted and forwarded to designated output destinations.

Abstract: A method, apparatus and article of manufacture for prioritization of control plane traffic in a router. A destination slot is allocated in a sliding window buffer via a control channel. A data packet is received via a data channel. An acknowledgement that the data packet was received is sent via the control channel. The destination slot is released via the control channel.

Abstract: In a method for controlling the heat transfer in a process for molding an optical disc of the type having a plurality of laser readable depressions of a predetermined quality, the process steps include injecting molten thermoplastic material into a mold having opposing surfaces for replicating respective opposite sides of the disc and imparting optically readable depressions of a predetermined quality to at least one side of said disc, opposing thermally conductive members, and a pair of insulating members, with each insulating member positioned between said conductive mold body and a respective opposing thermally conductive member, maintaining said thermally conductive mold body at a temperature less then about 90 degrees Centigrade wherein said insulting members are selected so that the molten thermoplastic resin is evenly and rapidly cooled from opposing sides to a temperature within about 5 degrees Centigrade of the glass transition temperature of said resin.

Abstract: An annular shaft seal including a continuous lip sealing element for sealing against oil flow between a bore and a shaft extending through the bore includes a convoluted elastomeric flexible section which connects the sealing element with a rigid case support. The flexible section is defined by a plurality of annuli, wherein each adjoining pair of annuli defines a reverse bend therebetween. One or more of the reverse bends is reinforced with a relatively non-elastic material, preferably plastic, which is integrally molded thereinto, and provides a torsional rigidity while permitting radial flexibility. This provides a closer following of the lip seal element on the shaft under conditions of extreme runout wherein the lip seal element would otherwise become dynamically distorted.
