    摘要: A method and system for determining a camera-to-display latency of an electronic device (100) having a camera (134) and touch-sensitive display (108) are disclosed. In one example embodiment, the method (500) includes receiving (511) first light (136) at the camera, and essentially simultaneously receiving second light (138) at a first photosensitive structural portion (102, 602). The method (500) further includes detecting (512) a first simulated touch input at the display (108) in response to a first actuation of the first photosensitive structural portion (102, 602), receiving third light (140) at a second photosensitive structural portion (104, 604), the third light being generated based at least indirectly upon the received first light (136), detecting (514) a second simulated touch input at the display (108) as a result of the receiving of the third light (140), and determining the camera-to-display latency based at least indirectly upon the touch inputs (516).

    摘要: A method and apparatus for testing a capacitive touch screen of a touch panel as commonly implemented on mobile and other electronic devices (or another touch-sensing device) are disclosed herein. In at least some embodiments, the method involves placing the touch screen in relation to a photoconductive panel (for example, a panel made from Cadmium Sulfide) so that the device and panel are adjacent to one another. Then, the panel is illuminated in a known manner, for example, by way of an image displayed on a display of the touch panel. Further, upon illumination of the panel, the panel conducts in a manner correlated to the illumination. Due to this conducting, capacitance change(s) occur that should actuate the touch screen in a corresponding manner. The capacitance change(s) detected at the touch screen can be compared with the known illumination pattern to determine whether the touch screen is operating properly.

    摘要: A vacuum pump system for creating a high vacuum (below 10−7 TORR) especially useful for vacuum volumetric measurements such as are performed using a gas sorption analyzer on a particulate sample to determine particulate surface area and porosity using a dry, non-lubricant oil-free vacuum pumping system that includes a turbomolecular drag pump having its high vacuum side connected to a vessel that contains the particulate sample to be analyzed, and in series with a dry, oil-free diaphragm pump whose inlet or vacuum side is connected to the high pressure exhaust side of the turbomolecular drag pump thereby eliminating any possibility of oil vapor contamination of the sample since the turbomolecular drag pump and the diaphragm pump use essentially no oil as lubricants.
