Abstract: A control method in a mobile automation system including a mobile automation apparatus and a control server. The method comprises, at the mobile automation apparatus: receiving a task identifier and a plurality of task fragments from the control server, each task fragment containing (i) a subset of identifiers for respective sub-regions in a facility, and (ii) an operational constraint. The method further includes, for each task fragment: generating a path traversing the subset of sub-regions, and while travelling along the path, performing the identified task.

Abstract: A system and method for disabling header compression during an establishment and configuration of a communication protocol and communication channel between a pair of correspondents. The system comprises an initiating correspondent transmitting at least one PPP negotiation packet having at least one acceptable TCP/IP header compression option type. A software module of a responding correspondent intercepts and examines said at least one PPP negotiation packet before said at least one PPP negotiation packet reaches a PPP layer of the responding correspondent and modifies said acceptable TCP/IP header compression option type to an unacceptable TCP/IP header compression option type and transmits same to said PPP layer of the responding correspondent. The responding correspondent rejects said unacceptable TCP/IP header compression option type.

Abstract: A method and system for manipulating packet header compression parameters, by substituting at least one instruction set associated with a PPP negotiation packet at the PPP layer of a protocol stack, the at least one instruction set for use in establishing a communication protocol and channel between a pair of correspondents. The method includes the steps of a software module coupled to a first correspondent examining all PPP negotiation packets from a second correspondent; the software module determining whether a first instruction set is present in the PPP negotiation packet; the software module discarding said first instruction set and replacing the first instruction set with a second instruction set; and at the second correspondent receiving the second instruction set associated with a communication protocol information.

Abstract: A method for providing cryptographic functions to data packets at the PPP layer of a network stack is presented. The method includes the steps of intercepting PPP datagrams having at least one encapsulated IP packet en route along the protocol stack; decapsulating the PPP datagrams to retrieve the encapsulated IP packet, determining whether to process the IP packet by modifying the IP packet to provide the cryptographic functions, and encapsulating the IP packet for transmission to a next layer of the network stack.

Abstract: The present invention is directed at a method of providing stack memory in an operating system with stack memory constraints. During operation, software modules executing on the operating system may require more than the allotted stack memory, therefore, in order to avoid stack overflow, more stack memory is required. Therefore, in accordance with a preferred embodiment of the present invention, upon initial execution of the software module, a request is sent to the operating system for the provision of more stack memory. The operating system then returns an address location within the operating system's memory where more stack memory may be provided. A new stack pointer value corresponding to the new address location is stored in the stack pointer value register and the existing stack pointer value is then stored in a pre-determined register.
