Abstract: One or more of the classes is defined using an attribute or keyword that indicates that the one or more classes may be defined as singleton classes or non-singleton classes (a class that may be instantiated more than once). A compiler system converts the class to a singleton class when the compiler system receives a command or request indicating that the class is to be defined as a singleton class. Various optimizations may be performed when one or more of the classes in the source code are defined as singleton classes. The compiler system may not convert the class to a singleton class when the compiler system receives a command or request indicating that the class is to be defined as a non-singleton class.

Abstract: A compiler system analyzes source code for an application. The compiler system determines whether a class in the source code uses a singleton pattern even though the class is not defined as singleton class. The compiler system may optionally convert the class to a singleton class. The compiler system may also perform one or more optimizations when generating the application based on the source code.

Abstract: Embodiments relate to systems and methods for generating a progress indicator in a programming loop. In embodiments, a programming language or application programming interface (API) can contain a loop operator that registers the occurrence of each iteration in a loop, and passes that information to a user interface to display an indicator of loop progress to a programmer or user. The progress notification can be a thermometer-style graph, a progress bar, or other graphical or other display representing the progress of the programming or process loop. In embodiments, the progress indicator and related information can be dumped to a log file, to create a record of loop progress to review and perform debugging operations, in the event of a crash during execution of the loop.

Abstract: Embodiments of the present invention provide a multi-input comparative testing tool. The present invention looks at the internal structure of the software being tested and compares the two pairs of internal structures. In the present invention, the testing tool is capable of receiving multiple program code files or data files as its input. For each program code file, the testing tool generates a collection of problem objects and compares pairs of the problem collections with each other. The present invention may also run on data files having program code. For example, the present invention is capable of testing extensible markup language (XML) files to determine if they validate against a schema. Problem objects that are in both collections are identified and set aside. The remaining problem objects are then marked either as being resolved or new depending in which collection they exist.

Abstract: A method and apparatus for providing a portable device recommendation system. The method may include storing, on a portable device, preferences of a user of the portable device with respect to media content, and facilitating sharing of desirable media content between this user and a user of another portable device based on the user preferences.

Abstract: Embodiments of the present invention provide a tamper proof file system. In particular, the present invention utilizes a virtual block device that is coupled with a real block device and a private/public key pair. The virtual block device receives the original data and then digitally signs it with the private key. The virtual block device then passes the digitally signed data to the real block device for storage. In order to retrieve or verify the data, the virtual block device may provide the public key and an acknowledgment. The acknowledgment may include a hash of the public key. The virtual block device is configured to discard the private key and to be removed from the system based on a finite lifespan.

Abstract: Some embodiments of a method and an apparatus to provide interoperability between different digital content protection schemes have been presented. In one embodiment, a first copy of digital content encrypted using a first protection scheme is received from a user. In response to a request from the user, it is verified that the user is a rightful owner of the first copy without decrypting the first copy. A second copy of the digital content encrypted using a second protection scheme is sent to the user if the user is a rightful owner of the first copy.

Abstract: Method and apparatus for the production of fluoroscopic and radiographic x-ray images utilizing a portable hand-held and battery operated x-ray system. The system incorporates a unique high voltage power supply of diminutive size and weight which may be disposed totally within the hand-held system. By utilizing the system in conjunction with a currently available hand operated instant Polaroid film developer, the system provides total portability and field operability in both fluoroscopic and radiographic mode.

Abstract: Method and apparatus for the removal of particulate matter, fumes, mists and noxious gases from a gas stream utilizing selectively sized and electrically charged water droplets, preferably between 10 and 60 microns, that exhibit significantly enhanced affinity for smaller uncharged particles through dielectrophoretic attraction, said droplets being present in such relatively low concentration that performance is not limited by space charge. The charged droplets are caused to move relative to the gas stream by inertial and/or electrostatic means, at such a velocity and path as to maximize encounters between charged droplets and the particles to be collected.

Abstract: A method of spraying electrically charged particulate material to ground from a low flying airplane. The method includes the steps of imposing an electrical charge of given polarity upon an emitted primary spray of particulate material of sufficient magnitude to electrostatically enhance the deposition thereof and concurrently emitting a secondary spray of oppositely charged particulate material of selective character from said airborne source at a charge level of a magnitude to avoid material degradation of the charge on said primary spray intermediate its loci of emission and deposition.
