20090038013 | WIRELESS COMMUNICATION SECURITY WHEN USING KNOWN LINK KEYS - The present system may enhance security in device having a wireless interface while it is operating in a mode that may make it more vulnerable to predatory attacks. More specifically, the advent of certain development or support operating modes supported by particular wireless communication mediums, such as debug modes that allow other wireless devices to monitor messages coming and going from a wireless device for diagnostic purposes, may leave devices overly accessible while operating in such a mode. As a result, additional security measures are required in order to determine if a vulnerable mode should be enabled on a device, and further, whether another device should be allowed to establish a communication to a device operating in this mode. | 02-05-2009 |
20090276549 | Access for host stacks - This invention relates to a method, a computer program product, a device, and a system for using one host controller by at least two host stacks and handling accesses to the host controller based on access rules. | 11-05-2009 |
20090300239 | USB Connection - In the case of a universal serial bus (USB) connection, a host detects a connection of a peripheral to the host via a USB interface of the host. The host then generates an informative command, which includes information on capabilities of the host. This informative command is provided for transmission via the USB interface to the peripheral. The peripheral receives the informative command and may for instance evaluate the included information for selecting a suitable USB mode that is to be entered or for deciding on becoming a host itself. Alternatively or in addition, the host may generate a request command for retrieving information on all classes offered in all USB modes of a peripheral. | 12-03-2009 |
20090303906 | Allocation Of A Communications Channel To a Data Transfer Session - A method of allocating a communications channel to a data transfer session, the method including during the data transfer session: sending a first data transfer session packet via the communications channel then sending an additional packet or packets, that are not a part of the data transfer session, via the communications channel to hold the communications channel for the data transfer session. | 12-10-2009 |
20100040041 | SWITCHING ROLE OF APPARATUSES BETWEEN CONTROLLER (HOST) AND PARTICIPANT (DEVICE) TO SCHEDULE BI-DIRECTIONAL DATA - A method involving: sending from a first apparatus to a second apparatus a first message identifying the first apparatus and a second message scheduling a time period for reply; receiving at the first apparatus during the time period scheduled by the second message a third message sent by the second apparatus; and in response to receiving the third message, changing a role of the first apparatus so that it is operable to schedule bi-directional data transfer between the first apparatus and the second apparatus. | 02-18-2010 |
20110032882 | Method, Apparatus or Computer Program for Changing From Scheduled to Unscheduled Communication Modes - A method comprising: while in a first communication mode that uses scheduled communication, detecting when a number of packets communicated in an interval exceeds a threshold; and if the number of packets communicated in the interval exceeds the threshold, changing the communication mode from the first communication mode to a second communication mode that uses unscheduled communication and if the number of packets communicated in the interval does not exceed the threshold, remaining in the first communication mode. | 02-10-2011 |
