Abstract: A method and apparatus for detecting a class of viral code are provided. The apparatus comprises an heuristic analyzer and a search component. The heuristic analyzer heuristically analyzes a subject file and generates a set of flags along with statistical information. The search component uses the set of flags with statistical information to perform a search for a scan string and/or a statement type in the subject file. A positive detection alarm is triggered if the scan string and/or statement type is found at least a corresponding predetermined number of times. The heuristic analyzer may be rule-based and comprise an heuristic engine and heuristic rules. The search component also may be rule-based and comprise a search engine and viral code class rules.

Abstract: A collapsible mobile chair assembly comprises a frame having a pair of wheel axles which include rack gearing and are slidably mounted in said frame for axial moveable between an extended operating position and a retracted storage position. The rack gearing of the axles overlap and drivingly engaging a pinion gear provided on the frame, constraining the axles slidingly to move together in opposite directions. Two support plate assemblies are provided on opposing sides of the chair, a rear fork assembly extending from each support plate assembly. A front fork strut and a handle strut are each pivotally attached to each support plate for movement between an extended operational position and a retracted storage position. The front fork and handle struts include gearing formed thereon which mesh so as to constrain struts on respective sides to rotate together between their extended and their retracted positions.

Abstract: A peripheral device having a protocol communication chip is provided. The protocol communication chip is configured to manage communication between the peripheral device and a host computer over a serial bus. The protocol communication chip includes a bus interface and a link control and status register. The link control status register is provided for setting link parameters, and is configured to be either read or written by the host computer by the transmission of a 16 byte packet having a DataType 0. The 16 byte packet is an OUTDATA packet for control and an INSTART packet for status. The peripheral device is configured to receive device command information from the host computer using a DataType 1 packet, and host computer being configured to access data resident on the peripheral devices using a DataType 2 packet.

Abstract: A host controller for enabling communication between a host computer and a device over a serial link is provided. The host controller includes a bus interface circuit that is connected to a system bus of the host computer. The host controller further includes host controller registers to enable code configuration of the host controller for operation, initialize the device, and send commands to the device. A packet generator/decoder circuit is also provided for generating poll packets to be sent to the device and for sending and receiving packets to or from the device. The host controller also has a serializer/deserializer for converting parallel data received from the bus interface circuit and to be sent over the serial link to the device into serial data and converting serial data received from the serial link to parallel data to be sent to the bus interface circuit and to the host computer.

Abstract: A method for communicating data and control from a host computer to a device is provided. The method includes generating a packet at the host computer and transmitting the packet to the device. The device responding to the packet with a handshake, and the handshake includes one of an ACK, a NACK, and an ALERT. The ACK is indicative that the packet was received without errors and a next packet in a sequence of packets can be sent to the device, the NACK is indicative that the packet was received without errors but a re-transmission should be attempted, and the ALERT is indicative of an error condition at the device and a re-transmission should not be attempted.
