Coding techniques for a (e.g., OFDM) communication system capable of transmitting data on a number of "transmission channels" at different information bit rates based on the channels' achieved SNR. A base code is used in combination with common or variable puncturing to achieve different coding rates required by the transmission channels. The data (i.e., information bits) for a data transmission is encoded with the base code, and the coded bits for each channel (or group of channels with the similar transmission capabilities) are punctured to achieve the required coding rate. The coded bits may be interleaved (e.g., to combat fading and remove correlation between coded bits in each modulation symbol) prior to puncturing. The unpunctured coded bits are grouped into non-binary symbols and mapped to modulation symbols (e.g., using Gray mapping). The modulation symbol may be "pre-conditioned" and prior to transmission.

Methods and devices for transmitting micromechanical forces locally to induce surface convolutions into tissues on the millimeter to micron scale for promoting wound healing are presented. These convolutions induce a moderate stretching of individual cells, stimulating cellular proliferation and elaboration of natural growth factors without increasing the size of the wound. Micromechanical forces can be applied directly to tissue, through biomolecules or the extracellular matrix. This invention can be used with biosensors, biodegradable materials and drug delivery systems. This invention will also be useful in pre-conditioned tissue-engineering constructs in vitro. Application of this invention will shorten healing times for wounds and reduce the need for invasive surgery.

A system and method is disclosed for forwarding location dependent messages from a message sender's mobile cellular device to an intended recipient's mobile cellular device. The method is principally practiced in a communication network comprising a plurality of mobile cellular devices having location determining capabilities such as triangulation and GPS. In an embodiment, the message sender identifies an intended message recipient and selects a geographic location and corresponding radius of circumference defining geographic pre-conditions for transmitting the location dependent message to the intended message recipient. The message is first transmitted to a central server which periodically monitors the geographic location of the intended recipient in real time or near real-time to determine if the intended recipient enters within the radius of circumference of the geographic location selected by the message sender. The message is transmitted from the central server when it is determined that the intended recipient has satisfied the geographic pre-conditions. In other embodiments, a cellular mobile device user is alerted when one or more contacts of the user arrives within a certain geographic proximity of the user.

A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a throughdrying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the throughdrying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the throughdrying fabric when the dried sheet is applied to the surface of the creping cylinder.

System for increasing a target zone for electrical ablation includes a treatment control module executable by a processor. The control module directs a pulse generator to apply pre-conditioning pulses to subject tissue cells in a pre-conditioning zone to electroporation, the pre-conditioning zone being smaller than a target ablation zone. After the pre-conditioning pulses have been applied, the control module directs the pulse generator to apply treatment pulses to electrically ablate the tissue cells in the target ablation zone. The pre-conditioning pulses cause the pre-conditioning zone to have a much higher conductivity so that the zone acts as a larger electrode area when the treatment pulses are applied, which results in a much larger target ablation zone than otherwise possible.

System and method for performing a splice operation on an encrypted or unencrypted MPEG-2 transport stream. A splice trigger is received at a pre-conditioning encoder. In response, the encoder generates, e.g., an SCTE-35 cue message that is intended to be received by a splicer. Also in response to the splice trigger, the encoder encodes / conditions a network feed such that a decoder buffer delay reaches a predefined value at a video frame of the network feed that corresponds to a splice point indicated by the SCTE-35 cue message. The network feed may then be encrypted in a known fashion. At the splicer, another feed is switched into the stream at the splice point, wherein the another feed is encoded such that a decoder buffer delay at a video frame of the another feed corresponding to the splice point is the same as the predefined value. The predefined value is defined as DTS−STC, where DTS is a Decoding Time Stamp and STC is a System Time Clock. The pre-conditioning encoder generates around the splice point audio PES packets that contain a single aligned audio frame.
