Responsive to the current speed exceeding the threshold value, the speed based setting controller automatically assigns a separate speed based setting to a current setting for each feature assigned to the threshold value, wherein each current setting for each feature designates the operability of that feature within the portable communication device, such that the current setting for each feature adjusts with a speed of travel as detected by the portable communication device.

Abstract: A recording system receives a broadcast signal from at least one service provider. An offset controller of the recording system samples a portion of the current broadcast signal on a particular channel over a particular interval of time. The offset controller then compares the sampled portion with a selection of features anticipated to be broadcast during the particular interval of time. Next, if the offset controller detects that a particular feature from among the selection of features matches within the portion of the current broadcast signal, then the offset controller calculates an offset time from a difference between an expected time for broadcast of the particular feature and an actual time of broadcast. The recording time for a program to be recorded is initially set to the start time and end time from a predetermined broadcast schedule.

The scroll-based volume controller, responsive to detecting the user selection to scroll through the browser window, calculates a change in position of the display element relative to the browser window. The audio element may include an audio file that is downloaded or streamed to the browser.

Abstract: A method is provided for transferring data between first and second nodes of a network. Such method includes requesting first data to be transferred by a first upper layer protocol (ULP) operating on the first node of the network; and buffering second data for transfer to the second node by a lower protocol layer lower than the first ULP, the second data including an integral number of standard size units of data including the first data. The method further includes posting the second data to the network for delivery to the second node; receiving the second data at the second node; and from the received data, delivering the first data to a second ULP operating on the second node. The method is of particular application when transferring the data in unit size is faster than transferring the data in other than unit size.

Abstract: An apparatus and method for verifying the audio output at a client device are provided. With the apparatus and method, when a user requests access to resources, a profile for the user is retrieved and used to determine whether the user is to be presented with audio advertisements. If so, a test audio advertisement is sent to the client device. An agent application on the client device outputs the audio advertisement, via a speaker, to the user and records the audio that is being output by the speaker using a microphone or other recording device. The recording of the audio output is then sent back to the server that sent the original test audio advertisement for comparison. The server then compares the recording of the audio output to the original test audio advertisement. If the recording matches the original test audio advertisement, access to the resources is granted.

Abstract: A method, system, and program for user controlled anonymity when evaluating into a role are provided. An anonymous authentication controller enables a user to control anonymity of the user's identity for role based network accesses to resources, without requiring reliance on any single third party to maintain user anonymity. First, a role authentication certificate is received from a role authenticator, wherein the role authentication certificate certifies that the holder of the role authentication certificate is a member of a particular role without allowing the role authenticator issuing the role authentication certificate the ability to track an identity of a user holding the role authentication certificate.

Abstract: A method, system, and program provide for voice mail management. A voice mail filtering controller calculates a separate Bayesian score for each voice mail message from among multiple voice mail message entries received into a voice mailbox for a user, wherein each separate Bayesian score indicates a probability that the associated voice mail message is unwanted by said user. During playback, the voice mail filtering controller automatically deletes a selection of the voice mail messages each with a separate Bayesian score greater than a particular Bayesian score of the last played voice mail message from the voice mailbox.

Abstract: A method, system, and program for efficient parallel bitwise sweeps of larger objects during garbage collection are provided. During a bitwise sweep, a helper thread scans a mark vector looking for a consecutive sequence of unmarked bits of a sufficient length following a marked bit. Once a consecutive sequence of unmarked bits of a sufficient length following a marked bit is detected, the helper thread fetches the size of a marked object corresponding to the marked bit. If the size of the marked object exceeds a size represented by the consecutive sequence of unmarked bits, the remainder of the bits representing the marked object are skipped, such that once a marked object is identified as potentially exceeding an object fetch threshold the helper thread efficiently skips the remainder of the bits represents the marked object and continues scanning for a number of consecutive zeroes indicating free space.

Abstract: A NAT data processing system is located behind a NAT enabled network with a NAT device as a gateway to the NAT enabled network. A client system located outside the NAT enabled network queries the NAT device for the address of the NAT data processing system located behind the NAT enabled network. The query is automatically routed through the NAT device to a DNS server. The DNS server then returns an address for the NAT data processing system and source routing for the NAT device. The NAT device forwards the address and source routing to the client system. Then, the client system sends packets to the NAT data processing system at the address with source routing through the NAT device, such that the NAT data processing system behind the NAT enabled network is directly accessed by the client system from outside the NAT enabled network.

Abstract: A multi-chip module (MCM) assembly has two modules interconnected by respective interposers and a printed circuit board, and diagnostic logic within the modules uses the principal of signal reflection to located any open fault in the circuit path across the interposers. A first test signal is sent from module to the other and a determination is made as to whether any reflected signal represents an open fault of the circuit path at either of the interposers. If a reflected signal is received during a predetermined time, the diagnostic logic concludes that a single open fault exists only at the far interposer. If no reflected signal is received then the diagnostic logic concludes that there is at least one open fault at the near interposer, and the second module runs a similar test to check to see if both interposers have failures.
