20080248098 | Polysaccharide Microparticles Containing Biological Agents: Their Preparation and Applications - A method of preparing polysaccharide glassy microparticles which are less than 10 μum in diameter and contain structurally delicate agents, such as proteins, peptides, gene materials, vaccines, antibodies, viruses and liposomes using low-temperature aqueous-aqueous emulsification (free of polyelectrolytes) and freezing-induced phase separation. When delicate agents are added to a polysaccharide-PEG two phase system followed by homogenization (or other shear adding process), the agents partition into the polysaccharide dispersed phase preferentially. These processes help to avoid aggregation of proteins caused by interaction with charged polyelectrolytes used for stabilizing the polysaccharide dispersed phase in our previously reported aqueous-aqueous emulsion. When this system is frozen and lyophilized, glassy particles less than 10 μm in diameter containing delicate agents can be formed. These fine polysaccharide particles protect proteins within their hydrophilic glassy matrix, and can therefore be easily suspended in hydrophobic polymer solutions and formulated to various forms of sustained release devices such microsphere, sheets, fibers, coating layers, and scaffolds. The particles can also be dispersed in hydrophilic gels to improve releasing kinetics and to deliver vaccines and antibodies for immune therapy. | 10-09-2008 |

20110019392 | CLAMP WITH LAMP - A clamp with lamp, particularly useful for attaching to an automobile battery, or similar rechargeable battery, when charging or otherwise working with the battery, is disclosed. The clamp with lamp is configured to provide a convenient source of light during nighttime or other low-light conditions and to provide an automated means for turning the light on and off during use. The clamp with lamp includes an LED lamp disposed on the upper jaw of the clamp, a battery disposed in a battery case inside the handle and a switching mechanism. A switching mechanism is actuated when the jaws of the clamp open, thereby providing power to the LED lamp. When the clamp is engaged with the automobile battery, and when the jaws are closed, the switching mechanism turns off the LED lamp to save electricity. The clamp is small, handy, elegant, and durable. | 01-27-2011 |
20110287673 | HIGH CONDUCTIVITY ENERGY-SAVING CLAMPING DEVICE - The high conductivity energy-saving clamping device comprises a clamp and a cable fixed upon the clamp. Inside the cable, the conductive material protrudes and is set on the juncture of the clamp and the external conductor. When the clamp is connected to the external conductor, the conductive material and the external conductor contact and meet. This invention possesses the following advantages: it simplifies the production technology, lessens raw materials needed for production and hence saves resources and cost by the direct contact of the conductive material and the external conductor; moreover, due to the increase of conductive contact area, it enhances the electrical conductivity by 10% to 15% compared to those common clamps which use tooth-like conductive parts to connect the external conductor. Meanwhile, the invention greatly decreases environmental pollution by omitting the plating process of tooth-like conductive parts. | 11-24-2011 |

20130338993 | NESTED EMULATION AND DYNAMIC LINKING ENVIRONMENT - Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs. Other embodiments concern accelerating dynamic linking by determining certain function calls that, rather than being processed through emulation of PLT code, are instead directly called without the need for PLT code translation. Some embodiments address both nested emulation and accelerated dynamic linking but other embodiments include one of nested emulation and accelerated dynamic linking. Other embodiments are described herein. | 12-19-2013 |
20140040921 | ISA BRIDGING WITH CALLBACK - Methods, apparatuses and storage medium associated with ISA bridging with callback, are disclosed. In various embodiments, at least one computer-readable storage medium may include instructions configured to enable a target device with a target ISA, in response to execution of the instructions, to provide an ISA bridging layer to the target device to facilitate a library service to callback a callback function of an application. The library service may be implemented for the target ISA, and the application may be implemented at least partially for a source ISA that may be different from the target ISA. The ISA bridging layer may include a source ISA emulator and a library emulator configured to cooperate to enable the application to call the library service, and the library service to callback the callback function, across the two instruction set architectures. Other embodiments may be disclosed or claimed. | 02-06-2014 |
20140046649 | ISA BRIDGING INCLUDING SUPPORT FOR CALL TO OVERIDDING VIRTUAL FUNCTIONS - Methods, apparatuses and storage medium associated with ISA bridging with support for virtual functions, are disclosed. In embodiments, at least one computer-readable storage medium may include instructions configured to enable a target device with a target ISA, in response to execution, to provide an ISA bridging layer to the target device to facilitate a library service of a library of the target device to call a virtual function of the library, while servicing an application operating on the target device, where the application has an overriding implementation. The ISA bridging layer may include a loader configured to load the application for execution, and as part of loading the application, detect the virtual function and modify a virtual function table of the application to enable the call. Other embodiments may be disclosed or claimed. | 02-13-2014 |
20140222410 | HYBRID EMULATION AND KERNEL FUNCTION PROCESSING SYSTEMS AND METHODS - One embodiment pre-builds translations of kernel functions (KFs) and loads them into a translation pool and corresponding indexed table. The KFs are thus quickly loaded and do not necessarily await trapping and emulation via a LIB emulator. This results in faster access to KFs. Other embodiments provide hybrid emulation where some application functions (e.g., those that need quick performance) are translated from a source ISA library while other applications functions are processed via emulation to a target ISA library. Doing so provides faster access to certain functions. Other embodiments are described herein. | 08-07-2014 |
