Method for generating dynamically configurable test doubles for software testing includes: detecting functions or methods invocations in a source code under test; collecting information about parameters and return types of one or more of original functions and original methods that are invoked by the source code under test, generating test doubles using source code with alternative definitions based on collected information; instrumenting the source code under test to replace the calls to one or more of original functions and methods with calls to the generated test doubles; and dynamically configuring runtime behavior of the generated test doubles, where all input parameters and return values of the one or more of original functions and original methods are provided to respective retrieved trigger objects by passing said input parameters and return values as arguments to function calls.

Dynamically configurable test doubles for software testing and validation

A device for generating power to run an electronic component. The device includes a heat-conducting substrate (composed, e.g., of diamond or another high thermal conductivity material) disposed in thermal contact with a high temperature region. During operation, heat flows from the high temperature region into the heat-conducting substrate, from which the heat flows into the electrical power generator. A thermoelectric material (e.g., a BiTe alloy-based film or other thermoelectric material) is placed in thermal contact with the heat-conducting substrate. A low temperature region is located on the side of the thermoelectric material opposite that of the high temperature region. The thermal gradient generates electrical power and drives an electrical component.

Microfabricated thermoelectric power-generation devices

A power source converts &agr;-particle energy into electricity by coulomb collision in doped diamond films. Alpha particle decay from curium-244 creates electron-hole pairs by freeing electrons and holes inside the crystal lattice in N- and P-doped diamond films. Ohmic contacts provide electrical connection to an electronic device. Due to the built-in electric field at the rectifying junction across the N- and P-doped diamond films, the free electrons are constrained to traveling in generally one direction. This one direction then supplies electrons in a manner similar to that of a battery. The radioactive curium layer may be disposed on diamond films for even distribution of &agr;-particle radiation. The resulting power source may be mounted on a diamond substrate that serves to insulate structures below the diamond substrate from &agr;-particle emission. Additional insulation or isolation may be provided in order to prevent damage from &agr;-particle collision. N-doped silicon may be used instead of N-doped diamond.

Electronic device featuring thermoelectric power generation

A system and method for determining a curvature of a specularly reflective surface based on optical interference. Two optical gratings are used to produce a spatial displacement in an interference field of two different diffraction components produced by one grating from different diffraction components produced by another grating. Thus, the curvature of the surface can be determined.
