Abstract: A driveshaft assembly, for example in an Electronic Unit Injector, Unit Injector or Electronic Unit Pump testing machine, wherein an indexing arrangement, such as complementary external and internal splines, enables a cam to be mounted on a shaft at a number of discreet positions, each providing a different offset of a central axis of the base cylinder section from a central axis of the shaft, each position providing a different maximum lift value of a plunger in contact with the cam, directly or via a rocker arm.

Abstract: A system, method and a computer readable medium for providing virtual learning of academic topic unrelated to languages in a non-native language of a student. The system includes an input device, which receives user input, a datastore, which stores the academic topic. At least a portion of the academic topic is stored in both native and non-native languages. The system further includes a processor, which obtains the academic topic based on the user input and an output device, which outputs the academic topic provided by the processor to a user. The academic topic is obtained by the processor with sheltered instruction in the non-native language. Upon a user request, the continuous providing of the academic topic is paused and at least one key term of the academic topic is provided in the native language.

Abstract: This disclosure is directed to a temples-less eyeglass frame having a central nose bridge portion, left and right lens frame portions, a left wing portion substantially perpendicular to the left lens frame portion, a right wing portion substantially perpendicular to the right lens frame portion, and left and right resilient foam temple bearing members attached to the inner end surfaces of the left and right wing portions, so as to rest in and exert pressure on both temple area only of the wearer when in use. Although the left and right wing portions can be integral with the left and right lens frame portions, this is not necessary. The left and right wing portions can be hingedly connected to the left and right lens frame portions, respectively, with or without spring-biasing to move the left and right wing portions inwardly when not being worn.
