An integrated circuit (IC) for optimizing data presentation to an external memory interface bus is provided. The IC is in communication with the external memory via the external memory interface bus. The IC includes an encoder that may encode the data that are being sent to an external memory. The encoder encodes the data based on the logic value of the majority of bits in the data. The encoder sets a status bit to indicate that the data are encoded. The encoder includes two encoding stages to further enhance the data integrity and transfer. Further connected in series with the encoder is a parity generator that sets the parity bit logic value based on whether the number of logic 1s in the data, including the status bit, is even or odd. The IC also includes a parity checker to detect whether any error occurred in the data during transmission. The decoder within the IC decodes the data to the original data.

A multilayer substrate minimizing differential loss is presented. The multilayer substrate for providing signals between an integrated circuit and a printed circuit board consists of a number of alternating electrically conductive and insulating layers. Differential signals are routed through the core insulating layer using differential pairs of plated through holes (PTHs). In addition, the multilayer substrate includes a number of plated through holes, which provide ground signals between conductive layers separated by the core layer. The multilayer substrate is configured such that a PTH providing ground is situated between each differential pair of plated ground holes, where the center or axis of each plated through hole is aligned in a collinear configuration.

In one embodiment, differential signaling and ground contacts are located in a rectilinear array of rows and columns with ground contacts spaced apart by three times the pitch distance between adjacent rows or columns and signaling contacts are located immediately adjacent the ground contacts. In particular, the two contacts of each differential pair are located one pitch distance apart from each other and one contact of each differential pair of contacts is located one pitch distance from a ground contact and the other contact of the differential pair is located approximately sqrt(2)*pitch distance from the same ground contact. In a second embodiment, differential signaling and ground contacts are located in a hexagonal array with ground contacts located three times the pitch distance between adjacent contacts and signaling contacts located immediately adjacent the ground contacts. In particular, the two contacts of each differential pair are located one pitch distance apart from each other and both contacts of each differential pair of contacts are located one pitch distance from a ground contact.

An improved power distribution network for an integrated circuit package that reduces the number of power supply pins that are used in the pin array and achieves better operating performance. In a preferred embodiment, the ratio of power supply pins to input/output (I/O) pins is in the range of approximately 1 to 24 to approximately 1 to 52. In this embodiment, the integrated circuit package comprises a substrate, an integrated circuit mounted on the substrate, a first decoupling capacitor mounted on the substrate, and a second decoupling capacitor formed in the integrated circuit. The package is formed by coupling a power supply pin to both the first and second capacitors by a low frequency path and a DC path, respectively, and the first and second capacitors are coupled by a high frequency path.

A system and method for producing a scaffold coated and/or impregnated with at least one bioactive agent. This is accomplished by culturing at least one cell in the same medium as a scaffold, but without physical contact between the at least one cell and the scaffold. The system includes a container having a surface defining an interior compartment. A medium is disposed within the interior compartment. At least one cell is disposed within the medium, the at least one cell being capable of producing at least one bioactive agent. Further, a scaffold is disposed within the medium. The scaffold is physically separated from the at least one cell such that there is no contact between the scaffold and the at least one cell. Thus, as the at least one cell produces at least one bioactive agent, such as a growth factor, the at least one bioactive agent enters the medium, and contacts and coats and/or impregnates the scaffold. However, due to the physical separation of the scaffold and at least one cell, the at least one cell is prevented from contacting and coating and/or impregnating the scaffold. Thus, only the desired bioactive agent or agents coat and/or impregnate the scaffold.

A statistical transition map is built based on mobile wireless device user mobility history data. This data is useful to assist various wireless local area network applications. Received signal strength and location trace information associated with movements of mobile wireless devices in a wireless network is collected. The received signal strength and location trace information is converted to a sequence of natural language pseudo-location word labels representing pseudo-locations of each mobile wireless device as each mobile wireless device moves about with respect to a plurality of wireless access point devices in the wireless network. A statistical transition map is generated for each mobile wireless device from the sequence of natural language pseudo-location word labels using a natural language model. A probability of a next pseudo-location for a particular mobile wireless device is computed based on its current location and its statistical transition map.
