An assessment of Motorola CodeLink microarray performance for gene expression profiling applications.

Abstract: DNA microarrays enable users to obtain information on differences in transcript abundance on a massively parallel scale. Recently, however, data analyses have revealed potential pitfalls related to image acquisition, variability and misclassifications in replicate measurements, cross-hybridization and sensitivity limitations. We have generated a series of analytical tools to address the manufacturing, detection and data analysis components of a microarray experiment. Together, we have used these tools to optimize performance in an expression profiling study. We demonstrate three significant advantages of the Motorola CodeLink™ platform: sensitivity of one copy per cell, coefficients of variation of 10% in the hybridization signals across slides and across target preparations, and specificity in distinguishing highly homologous sequences. Slides where oligonucleotide probes are spotted in 6-fold redundancy were used to demonstrate the effect of replication on data quality. Lastly, the differential expression ratios obtained with the CodeLink™ expression platform were validated against those obtained with quantitative reverse transcription–PCR assays for 54 genes.

Communicator having reconfigurable resources

Abstract: A communicator (10) includes a plurality of reconfigurable resource units (13) that can each be dynamically altered to perform any of a multitude of processing tasks. A controller (16) determines a plurality of processing tasks to be supported by the communicator (10) and configures the plurality of reconfigurable resource units (13) accordingly. A memory (18) stores a library of configuration files for use by the controller (16) in configuring the plurality of reconfigurable resource units (13). In one embodiment, the controller (16) continuously adapts the plurality of reconfigurable resource units (13) according to present system requirements.

Micromachined semiconductor probe card

Abstract: A semiconductor probe card having a plurality of micromachined probes tips for contacting an array of electrode pads formed on a semiconductor integrated circuit is provided. The plurality of probe tips are formed on the top surface of the substrate wherein the probe tips are arranged in an array matching of electrode pads on the integrated circuit to be tested. A portion of the semiconductor substrate underneath the probe tips is thin, so that the probe tips rests on a flexible diaphragm or beam.

Satellite cellular telephone and data communication system

Abstract: A system for facilitating global cellular/trunked mobile communication is disclosed. This system permits communication with hand held and mobile mounted cellular telephones. The system permits two-way communications anywhere on or above the earth up to a particular height above the earth of several hundred nautical miles. The system employs a number of low-earth orbiting satellites moving about the earth in orbit. Links are provided from the satellites directly to the users and via the public switched telephone network to other users. The satellites are interconnected via links in a ring structure surrounding the earth. Switching is performed by each of the satellites. In addition, each of the satellites hands off a call as it moves out of the range of a particular user.

Method and apparatus for authentication in a communication system

Abstract: A method and apparatus for authenticating a roaming subscriber. In a preferred embodiment, a subscriber receives a challenge (305) that is in a format of a local authentication protocol, and determines (310) whether the local authentication protocol is the subscriber's home system authentication protocol. If it is not, the subscriber converts the challenge into a format (e.g., bit length) compatible (325) with its home system authentication protocol, and processes the converted challenge with the subscriber's secret key and authentication algorithm into an authentication response (330). The authentication response is converted (335) to be compatible with the local authentication protocol, and transmitted (340) to a local system communication unit. The challenge and response is then forwarded to the subscriber's home system (345) for similar conversion and processing, and the subscriber's response is compared against a home system generated response (355).
