The drive units are located on a same side of the substrate and configured to drive the blade structure to rotate clockwise or counterclockwise.
Abstract:
A carbon nanotube film supporting structure is provided. The carbon nanotube film supporting structure is used for supporting a carbon nanotube film structure. The carbon nanotube film supporting structure includes a substrate and a number of protruding structures. The substrate has a surface defining a support region. The protruding structures are distributed on the support region. The carbon nanotube film structure can be peeled off completely after being in contact with the carbon nanotube film supporting structure. The present disclosure also relates to a method for using the carbon nanotube film supporting structure.
Abstract:
A transmission electron microscope (TEM) micro-grid includes a base and a plurality of electron transmission portions. The base includes a plurality of first carbon nanotubes and the first carbon nanotubes have a first density. Each electron transmission portions includes a hole defined in the base and a plurality of second carbon nanotubes located in the hole. The second carbon nanotubes have a second density. The second density is less than the first density. The base and the electron transmission portions form the TEM micro-grid for observation of a sample using a TEM microscope.
Abstract:
The present disclosure provides a digital sound projector including a first flat speaker, a second flat speaker, a connecting device and a signal input device. The connecting device pivotally connects the first flat speaker and the second flat speaker to form an angle between a surface of the first flat speaker and a surface of the second flat speaker. The angle is larger than 0 degrees and smaller than 180 degrees. The signal input device inputs electrical signals to each of the first and the second flat speakers.
Abstract:
A thermoacoustic device includes at least one first electrode, at least one second electrode, a sound wave generator and two protection components. The sound wave generator is electrically connected to the at least one first electrode and the at least one second electrode. The sound wave generator includes a carbon nanotube structure. The two protection components are located on opposite sides of the sound wave generator.
Abstract:
A semiconductor device may include a resistance pattern including a resistance material on a substrate. The resistance pattern may include first and second spaced apart base elements, a bridge element, and first, second, third, and fourth extension elements. The first and second base elements may be substantially parallel, and the bridge element may be connected between respective center portions of the first and second spaced apart base elements. The first and second extension elements may be connected to opposite ends of the first base element and may extend toward the second base element, and the third and fourth extension elements may be connected to opposite ends of the second base element and may extend toward the first base element. Related methods are also discussed.
Abstract:
A method, apparatus, and computer instructions for improving performance and scalability of common information model object (CIMOM) by using a hardware management console (HMC) repository. The HMC repository includes storage of HMC objects, an HMC object model and a common interface (CIM Wrapper) for accessing to HMC objects. The HMC object model allows the user to store and retrieve the CIM objects and their associations efficiently. A CIM provider may access HMC objects through a common interface (CIM Wrapper), so that different repositories are allowed to be used without significant changes to the underlying server code (CIM provider). A CIM provider may also call the HMC repository directly for more efficient operations because the number of times conversions made between the CIM object and the repository object are greatly decreased.
Abstract:
Techniques for end-to-end tracing of database operations in source code for database applications are provided. Source code on the client side is instrumented to measure time spent on selected database operation statements (e.g., queries). The selected database operation statements can be uniquely tagged or identified. Tracing is enabled on the database application on the server side so that a log is produced, where the log includes performance (e.g., time spent) information on database operation statements that are executed. The performance information in the log is correlated to the selected database operation statements so that, among other things, the time spent on the client side and the time spent on the server side can be presented for analysis.
Abstract:
A method, apparatus and computer instructions are disclosed for seamlessly transporting a language-independent message (e.g., embedded NLS emblems) encoded from a source code at a layer below a management framework, through the management framework, and on to a client layer for consumption by a user. Consequently, for example, the process of displaying an error condition message to a client can be decoupled completely from the point where the error occurred, but the details and context of the error can still be preserved. As such, a generic solution is disclosed that is independent of the NLS language and locale and particular management framework involved. Advantageously, for example, a system programmer can write a significant amount of a system's messaging code independently of the management framework involved.
Abstract:
According to some embodiments of the invention, both open loop and closed loop processing may be implemented by a transaction processor. For general, unrestricted transactions, the transaction processor may direct authorization to an open loop primary authorizing entity associated with a primary account number (PAN). For restricted transactions, the transaction processor may determine the appropriate closed loop authorizing entity (e.g., a transit agency, an insurer, a retailer, etc.). The transaction processor may further create an entry in a multi-access blockchain evidencing the transaction on the closed loop or restricted account with that authorizing entity. Thus, the multi-access blockchain may be kept up-to-date, allowing the closed loop authorizing entities to verify transactions and account balances instantaneously.
