摘要： The present invention discloses an analogue-to-digital converter comprising at least two voltage comparator devices. Each of the voltage comparator devices comprises a differential structure of transistors and is arranged for being fed with a same input signal and for generating an own internal voltage reference by means of an imbalance in the differential structure, said two internal voltage references being different. Each voltage comparator is arranged for generating an output signal indicative of a bit position of a digital approximation of the input signal.

摘要： The present invention relates to an instrument for treating amblyopia using automatic frequency conversion laser, comprises a laser generator, a circular lightproof system installed on the output light path and a control circuit, also comprises an angular rotation expander for adjusting height and light path output angle. The angular rotation expander comprises a primary drawtube having a primary lens, set outside of a secondary drawtube having a secondary lens. The primary drawtube is set outside of the secondary lens and can reciprocate along it. A retainer is equipped on the upper position of the secondary drawtube. There is an opening on one side of the primary drawtube for leaving the light out, a reflector is set inside of the primary lens facing the opening. Light outputted by the laser generator is transmitted directly to the secondary lens, and then to the primary lens, and finally is sent out from the opening after reflected by the reflector.

摘要： Determination of a target category associated with a business listings query is provided. A query categorization system initially generates a mapping of internal categories of the query categorization system to target categories of a search engine service. The query categorization system receives a business listings query and identifies business listings that match the query. The query categorization system identifies an internal category associated with each matching business listing. The query categorization system then identifies from the mapping the target categories that correspond to the identified internal categories. The query categorization system selects one of the identified target categories as the category to be associated with the query.
