Abstract: A single piece light pipe is designed to provide dual-field, multi-color, multi-directional illumination. The light pipe is combined with a single PCB having a plurality of LEDs to create a compact illuminator that can selectively provide dark field and bright field with red, green, blue color, broad spectrum, or combination of any color in horizontal, vertical, diagonal, or combination of any direction. The single piece light pipe is compact in size and light in weight. The non-closed form option not only can further reduce the weight but also can allow arrange opening area clearance for: (1) visual aiming and alignment in application, especially for hand held application; (2) reducing illumination crosstalk to unwanted directions; and for (3) mechanical integration. The improvements allow the illuminator to read direct product marking (DPM) type of barcodes.

Abstract: Methods, systems, and computer-readable media for simulating advertising auction results for a listing using auction data from auctions in which the listing previously participated. The simulation allows an advertiser to determine a bid price that would have resulted in a particular outcome. The simulation may be performed by rerunning auctions in which the listing participated by maintaining the characteristics of all other bids that actually participated in the auction while changing the bid price for the listing being simulated. The simulation may be repeated multiple times with different bid prices to create a distribution of auction results that correspond to various bid prices.

Abstract: A computer automatically changes a web page that would otherwise be normally generated by a first application program (such as a web-conferencing tool for example) in a first language (e.g. English), by adding metadata to one or more translatable text strings in the web page. The changed web page is displayed to a human translator by a second application program (e.g. the browser is equipped with a plug-in) to receive translation(s) of the translatable text string(s) into a second language (e.g. French). The translations are used as replacements for the translatable text strings, to create a translated version of the first application program, in the second language.
