Abstract: A partition-based method for diagnosing memory leaks in Java systems, comprising dividing heap memory of a Java virtual machine into a plurality of partitions based on a partition plan, wherein each partition has at least one partition owner; monitoring the status of the respective partitions to determine whether there is a partition in which the memory space is exhausted; and if there is a partition in which the memory space is exhausted, determining that the memory leak may occur in the partition and analyzing the partition to obtain leaked objects and objects related to the leaked objects. The present invention also provides a partition-based apparatus for diagnosing memory leak in Java systems.

Abstract: A repeater for connecting a host and a device in a WUSB environment, the repeater comprising: host interfacing means for establishing a secure wireless data communication channel for data communication with a host, device interfacing means for establishing a secure wireless data communication channel for data communication with a device, data buffer for storing data for subsequent onward transmission to either said host or said device, and scheduler for scheduling timing of onward transmission of data from said data buffer to either said host or said device.

Abstract: A communication interface facilitates connection of a plurality of wireless USB compatible hosts with at least a WUSB device in a wireless USB environment at the same time. The communication interface includes a host detector that detects the presence of an active host or a plurality of active hosts, a host communicator for establishing wireless USB connection with a plurality of hosts, and a controller for causing time division multiplexed (TDM) data communication between active hosts and at least one device.
