Systems and methods for a wireless communication system used for transmitting and receiving information, the information not containing identification of the information's intended recipient. A method for transmitting payload information, the method comprising providing verification information scrambling a portion of the verification information and transmitting the payload information with the scrambled verification information portion. Also provided is a method for processing transmitted payload information incorporated into an encoded information message with scrambled verification information, the method comprising receiving the encoded information message descrambling at least a portion of the scrambled verification information and comparing said descrambled verification information with predetermined verification information processing said payload information based on said comparison.

摘要:
In one embodiment, a scheme is provided for securing a personalized indicium assigned to a mobile communications device. Upon detecting at a mobile communications device that one of a list of criteria have been met, a challenge-and-response procedure is initiated by the mobile communications device. During the challenge-and-response procedure, the mobile communications device and a network node will authenticate the personalized indicium using a shared authentication key.

A wireless communication system, comprising a host service, a wireless router system coupled to the host service, a wireless network coupling the wireless router system and a wireless mobile communication device (“mobile device”), adaptively delivers data to the mobile device in the wireless communication system using a notification message delivery mechanism. Mobile device reports its session state to the wireless router at a regular interval or if there is a change in state. The host service sends out a message to the wireless router to query the state of the mobile device. If the state of the mobile device is determined to be in coverage (or logged on), the host service sends down the data message to the mobile device using a payload message (MTH) with certain parameters configured. The data is temporarily stored at the wireless router. If the device is available, the message is sent to the device over the wireless network. If the device is not available, the wireless router returns the payload message back to the host service, updating the status of the device. The wireless router also reports to the host service any change in device state. If the device is back in coverage, the payload message is then resent from the host service to the device.

In one illustrative example, a method in a wireless router system for transmitting data packets to a mobile communication device through the wireless communication network based upon a round trip time associated with communication of each data packet is provided. The round trip time is a time period between the transmission of each data packet and reception of a corresponding acknowledgement signal from the mobile communication device. A number of data packets matched for a window size are transmitted to the mobile communication device, and a round trip time associated with communication of each of the transmitted data packets is measured. The window size for data packet transmission is re-sized by increasing the window size if the round trip time associated with the communication of each of the transmitted data packets is within a first time threshold, and decreasing the window size if the round trip time associated with the communication of any of the transmitted data packets is more than the first time threshold but less than a second time threshold. The window size is also decreased if the round trip time of any of the transmitted data packets is more than the second time threshold, where each such data packet is further marked as a lost data packet. A number of data packets matched for the re-sized window is subsequently transmitted, including a retransmission any data packets marked as lost. The steps of the method are repeated from the measuring step until data packets to be transmitted are exhausted.

摘要:
An apparatus for assembling seatbelt webbing with a sill-end bracket has a form-feeding member with a tapered channel for receiving one end of a length of seatbelt webbing on an assembly line. A webbing pull-through member engages one end of the webbing. A bracket sensor senses the presence of a bracket at a correct position in the bracket support. Means responsive to a signal from a sensor may be provided for indicating the correct positioning of the sill-end bracket for feeding the pull-through member through the sill-end bracket. Means for driving the webbing into the tapered channel are provided so that said one end is located at a predetermined position relative to the form-feeding member. A method of manual or automatic assembling seatbelt webbing with a sill-end bracket is also disclosed.

A banked purification system having, in flow series, an inlet for entry of a fluid, a bank of two or more purification columns in which the fluid is purified by a purifying component, and an outlet for discharging the purified fluid, the columns being arranged in parallel such that the fluid from the inlet splits at first ends of the columns into respective streams which flow through the columns and recombine at second ends of the columns for onward travel to the outlet; wherein the columns have first ports in the side walls of the columns at the first ends, the first ports being connected to each other such that the first ends are placed in fluid communication to create a manifold from the first ends of the columns which splits the fluid from the inlet into said streams.

A filter assembly is provided for removing entrained material from a fluid stream. The assembly includes a manifold with a port through which the fluid is received into or removed from the assembly, and a housing into which is inserted a tubular filter element having walls of a filtration medium. The housing and the manifold have joining formations which allow them to be joined together and separated apart by relative rotation. The filter element has an end cap thereon which sealingly engages with the manifold. The end cap has an opening therein which accepts fluid received through the port and feeds the fluid into the interior of the filter element or which accepts fluid received from the interior of the filter element and feeds the fluid to the port. The filter element is insertable into the housing along the axial direction of the filter element.
