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.

Improving throughput performance when applying deblocking filters on reconstructed image frames. In one embodiment, an image frame received in the form of a set of values in encoded format is decoded to form a second set of values representing a reconstruction of the image frame in a decoded format. The specific one of the pairs of edges (formed by sub-blocks in the image frame) to which a deblocking filter is to be applied is then determined by evaluating any pre-conditions that need to be satisfied according to a standard. The deblocking filter is then applied to the determined specific ones of the pairs of edges, with the application being performed after determining.

Textured silicon solar cells and techniques for their manufacture utilizing metal sources to catalyze formation of randomly distributed surface features such as nanoscale pyramidal and columnar structures. These structures include dimensions smaller than the wavelength of incident light, thereby resulting in a highly effective anti-reflective surface.

Methods and pharmaceutical compositions for preconditioning and/or providing neuroprotection to the animal central nervous system against the effects of ischemia, trauma, metal poisoning and neurodegeneration, including the associated cognitive, behavioral and physical impairments. In one embodiment, the method is accomplished by stimulating and stabilizing hypoxia-inducible factor-1α (HIF-1α). HIF-1α is known to provide a neuroprotective benefit under ischemic conditions. Patients at risk for certain diseases or disorders that are associated with risk for cerebral ischemia may benefit, e.g., those at risk for Alzheimer's disease, Parkinson's disease, Wilson's disease or stroke or those patients having head or spinal cord injury. Patients undergoing certain medical procedures that may result in ischemia may also benefit. Initially, the possibility of ischemia or neurodegeneration is recognized. Intranasal therapeutic agents are administered to the upper third of the nasal cavity to bypass the blood-brain barrier and access the central nervous system directly to avoid unwanted and potentially lethal side effects. Therapeutic agents include those substances that interact with iron and/or copper such as iron chelators, copper chelators, and antioxidants. A particular example of such therapeutic agents is the iron chelator deferoxamine (DFO). Intranasal administration of DFO is known to stimulate and/or stabilize HIF-1α and provides an efficient and safe method for pre-conditioning the brain to protect against cerebral ischemia. Moreover, DFO is shown to decrease weight loss in subjects when administered pre and/or post stroke.

A system for thermally pre-conditioning a vehicle's passenger cabin prior to vehicle departure is provided. The system, after determining that the vehicle is off and/or the driver has left the car, monitors a variety of conditions corresponding to both the vehicle and the driver in order to determine the probability of the driver requiring near-term use of the car. Typical monitored conditions may include driver and vehicle location, driver proximity, time of day, day of week, driver's upcoming appointments, and a historical data base that tracks driver behavior. Once the probability that the car will be needed within a preset time period exceeds a preset level, the system determines whether the passenger cabin should be heated or cooled based on the current passenger cabin temperature, and then activates an appropriate thermal management system.

Embodiments of the presently claimed invention automatically and systematically schedule jobs in a computer system thereby optimizing job throughput while simultaneously minimizing the amount of time a job waits for access to a shareable resource in the system. Such embodiments may implement a methodology that continuously pre-conditions the profile of requests submitted to a job scheduler such that the resulting schedule for the dispatch of those jobs results in optimized use of available computer system resources. Through this methodology, the intersection of the envelope of available computer system shareable resources may be considered in the context of the envelope of requested resources associated with the jobs in the system input queue. By using heuristic policies, an arrangement of allocations of available resources against requested resources may be determined thereby maximizing resource consumption on the processing system.

Methods and pharmaceutical compositions for preconditioning and/or providing neuroprotection to the animal central nervous system against the effects of neurological disorders involving ischemia, trauma, metal poisoning and neurodegeneration, including the associated cognitive, behavioral and physical impairments. In one embodiment, the method is accomplished by stimulating and/or stabilizing hypoxia-inducible factor-1α (HIF-1α). HIF-1α is known to provide a neuroprotective benefit under ischemic conditions.
