Abstract:
A transconductance input apparatus energized by supply voltage has an input for receiving an input signal, and an output for delivering an output signal. The apparatus also has a plurality of transconductance stages for converting the input signal into the output signal, which is substantially free of dead zones when the total supply voltage is 2.7 volts or less.
Abstract:
An image retrieval system performs both keyword-based and content-based image retrieval. A user interface allows a user to specify queries using a combination of keywords and examples images. Depending on the input query, the image retrieval system finds images with keywords that match the keywords in the query and/or images with similar low-level features, such as color, texture, and shape. The system ranks the images and returns them to the user. The user interface allows the user to identify images that are more relevant to the query, as well as images that are less or not relevant to the query. The user may alternatively elect to refine the search by selecting one example image from the result set and submitting its low-level features in a new query. The image retrieval system monitors the user feedback and uses it to refine any search efforts and to train itself for future search queries. In the described implementation, the image retrieval system seamlessly integrates feature-based relevance feedback and semantic-based relevance feedback.
Abstract:
The present invention is directed to methods for diagnosis and treatment of systemic lupus erythematosus and drug-induced systemic lupus erythematosus. More specifically, the specification describes methods using a lysosomal phospholipase A2 in methods for the diagnosis and treatment of autoimmune disorders such as systemic lupus erythematosus and drug-induced systemic lupus erythematosus.

Abstract:
An I/O circuit includes load sense and active noise reduction features that result in high speed output signal transitions with very low noise. Capacitive feedback control circuitry controls the point and time at which feedback capacitors are applied to the gate drive of the I/O circuit output stage. Active device feedback control controls the output stage gate drive.

Abstract:
An axle positioning structure to provide stable positioning and an automatic reposition function includes an axle and a rotary member. The axle has a stem with an axial tangent surface. The rotary member has a non-continuous annular sleeve slightly larger than the outer diameter of the stem. The annular sleeve has a pressing surface on an end corresponding to the axial tangent surface. The pressing surface can be swiveled away from the axial tangent surface and then press on the perimeter of the stem such that the inner diameter of the annular sleeve is expanded to provide a pressing force for the stable positioning. When the pressing surface is swiveled to the middle portion of the axial tangent surface, the pressing surface escapes from the perimeter of the stem so that the annular sleeve provides a returning force to automatically return to the original position.

Abstract:
Provided are devices and methods featuring a nanoelectronic interface between graphene devices (for example, field effect transistors or FETs) and biomolecules such as proteins, which in turn provides a pathway for production of bioelectronic devices that combine functionalities of the biomolecular and inorganic components. In one exemplary application, one may functionalize graphene FETs with fluorescent proteins to yield hybrids that respond to light at wavelengths defined by the optical absorption spectrum of the protein. The devices may also include graphene in electronic communication with a biomolecule that preferentially binds to a particular analyte.
