Abstract: Methods, systems, and related computer program products for photolithographic process simulation are disclosed. In one preferred embodiment, a resist processing system is simulated according to a Wiener nonlinear model thereof in which a plurality of precomputed optical intensity distributions corresponding to a respective plurality of distinct elevations in an optically exposed resist film are received, each optical intensity distribution is convolved with each of a plurality of predetermined Wiener kernels to generate a plurality of convolution results, and at least two of the convolution results are multiplied to produce at least one cross-product. A weighted summation of the plurality of convolution results and the at least one cross-product is computed using a respective plurality of predetermined Wiener coefficients to generate a Wiener output, and a resist processing system simulation result is generated based at least in part on the Wiener output.

Abstract: A breast x-ray system and method using tomosynthesis imaging in which the x-ray source generally moves away from the patient's head. The system may include an operation mode in which it additionally takes mammogram image data.

Abstract: The present invention relates to an apparatus and a method for wireless purchase of merchandise from a vending machine by using a cellular mobile phone. The present invention permits a cellular mobile phone user to dial a sequence of code on the phone to invoke the vending machine to dispense merchandise, where payment is charged to the mobile phone account. The present invention also relates to an apparatus and a method for on-line inventory management. With on-line inventory management, the present invention provides high efficient operation, reduced operation cost, and just-in-time service and merchandise delivery. The present invention further relates to an apparatus and a method that allow both on-line inventory management and wireless purchase of merchandise in a vending machine.

Abstract: A reversible thermosensitive recording medium having a supporting substrate and a reversible thermosensitive recording layer formed on the supporting substrate, being capable of reversibly varying color density depending upon temperature with improved durability, is provided. The recording medium has the rates of changes in recording sensitivity and in erasure sensitivity, which are caused by the immersion in an artificial perspiration liquid, of 50% or less and 80% or more, respectively, and an average maximum particle size of organic materials of 2.5 microns at most.
