Patent number: 8698770Abstract: An active touch system is provided, in which sensing electroding units in an array and two groups of intersecting control electrodes and detecting lines are disposed on a touch substrate, and the detecting lines are connected to sensing electrodings through active devices. The control electrodes are used to control on and off of the active devices, and the detecting lines are used to apply touch excitation signals to the sensing electrodings, and detect a leakage current of a sensing electroding to a finger or other touch object. A position of the finger or other touch object on the touch substrate is found by determining a sensing electroding unit generating the leakage current. The method of obtaining touch signals is improved in the hardware sensing stage, so that the judgment procedure after detection is greatly simplified, and the judgment of multi-point touch becomes easy and natural.Type: GrantFiled: January 11, 2012Date of Patent: April 15, 2014Assignee: Solution Depot (Shenzhen) LimitedInventor: Qiliang Chen

Patent number: 8610680Abstract: A touch screen flat panel display (FPD) is provided, which includes a display screen, a display driving circuit, a touch system circuit, and the like. Related circuits in the touch screen FPD enable electrodes of the display screen to transmit display driving signals as well as touch signals, that is to say, the display driving and the touch detection multiplex the electrodes of the display screen, such that the FPD is not only used for normal display but also used for realizing touch detection. By applying the touch signal simultaneously to detecting lines and non-detecting lines, the flow of the touch signal between the detecting lines and between the detecting line and the non-detecting line is reduced, thus controlling the flow direction of the touch signal, and increasing the accuracy of determining touched electrodes.Type: GrantFiled: January 12, 2011Date of Patent: December 17, 2013Assignee: Solution Depot (Shenzhen) LimitedInventors: Qiliang Chen, Haiping Liu, Meiying Chen

Publication number: 20120330919Abstract: Computer-implemented methods, systems, computer program products for generating cross-language query suggestions are described. A pair of machine-generated translations are obtained for a primary-language query suggestion. A first machine-generated translation of the pair is generated by machine-translation from a first language to a second language, while the second machine-generated translation is generated by machine-translation from the second language to the first language. A respective difference measure is determined for each machine-generated translation based on the number of n-grams the machine-generated translation has in common with the primary-language query suggestion. The machine-generated translation that has a smaller number of n-grams in common with the primary-language query suggestion is identified as a preferred choice as a cross-language query suggestion for the primary-language query suggestion.Type: ApplicationFiled: September 29, 2011Publication date: December 27, 2012Applicant: GOOGLE INC.Inventors: Qiliang Chen, Weihua Tan

Publication number: 20120330990Abstract: Computer-implemented methods, systems, computer program products for generating cross-language query suggestions are described. For each query suggestion written in a first natural language, candidate segmentations are generated from the query suggestion, and candidate translations are generated from each candidate segmentation. The candidate translations are evaluated based on a measure of segmentation quality associated with the respective candidate segmentation from which each candidate translation is derived, and a frequency of occurrence of the candidate translation in a target language query log. The measure of segmentation quality associated with each candidate segmentation is further based on a frequency of occurrence of the candidate segmentation in a source language query log. A candidate translation is provided as a cross-language query suggestion for the primary language query suggestion based on the result of the evaluation.Type: ApplicationFiled: September 29, 2011Publication date: December 27, 2012Applicant: GOOGLE INC.Inventors: Qiliang Chen, Weihua Tan

Publication number: 20120330989Abstract: Computer-implemented methods, systems, computer program products for automatic language-detection for search queries are described. A character-to-language mapping is stored on a client device. The client device can process each query character of a search query to determine a number of candidate “language-writing system” pairs in which the query character can exist according to the character-to-language mapping. A respective sub-score can be generated for each candidate “language-writing system” pair in the context of each query character that is associated with the candidate “language-writing system” pair. A final score can be calculated for each candidate “language-writing system” pair by aggregating all the sub-scores that have been generated for the candidate “language-writing system” pair. A source language of the search query can be determined based on the respective final scores of all the candidate “language-writing system” pairs identified for the search query.Type: ApplicationFiled: September 29, 2011Publication date: December 27, 2012Applicant: Google Inc.Inventors: Weihua Tan, Qiliang Chen
