Patents

Patent:	基於中文字型架構之反向人機辯識碼之辨識方法
Inventors:	陳伶志、莊德明、朱文園、余孝萱、陳福維
Country:	臺灣
Date of Patent:	2014/08/01–2030/06/17
Abstract:	本發明提供一種基於中文字型架構之反向人機辨識碼之辨識方法，其係掃描中文字得到未知字圖檔後，利用軟體初步篩選出數個候選字，並將其拆解為數個候選部件，接著搭配中文字型架構人機辨識碼(CAPTCHA)的使用，確保每個候選部件皆被使用者答過一定次數後，依照答題記錄算出極可能與極不可能為未知字之兩個候選部件集合，分別為第一字集與第二字集，接著根據此二集合配合一組隨機產生之中文字型架構人機辨識碼來驗證使用者答題之正確性，以更新集合，反覆驗證直到歸納出未知字的漢字字型，即完成辨識。

Patent:	利用移動速度控制無線電開關之操作方法及其無線電設備
Inventors:	黃寶儀、林柏言、陳伶志、黃致豪
Country:	臺灣
Date of Patent:	2013/11/21–2030/07/21
Abstract:	本發明有關於一種利用移動速度控制無線電開關之操作方法及其無線電設備，結構包括有一速度估算器及一運算器，速度估算器估算無線電設備的移動速度，而運算器比對移動速度與一速度門檻值間的大小，以切換無線電設備的開關機，藉此，根據移動速度來控制無線電設備的開關機，以降低無線電設備的開機時間，減少無線電設備的電源支出。

Patent:	時間同步裝置、系統及其方法
Inventors:	黃寶儀、劉承榮、陳伶志、黃致豪
Country:	臺灣
Date of Patent:	2013/11/11–2030/07/11
Abstract:	本發明係關於一種時間同步裝置、系統及其方法，尤指一種可降低功耗且維持同步準確度之時間同步裝置、系統及其方法。其裝置主要包含有一GPS接收器、一微處理器及一震盪器，利用GPS接收器定位完成後產生之PPS訊號校正微處理器根據震盪器所產生之時鐘訊號。校正完成後關閉GPS接收器以節電，並於一預設時間後再次開啟GPS接收器。再以定位完成後之PPS訊號修正時鐘訊號。

Patent:	Operation Method and Radio Device for Controlling Power Switch of Radio Based on Moving Speed
Inventors:	Polly Huang, Po-Yen Lin, Ling-Jyh Chen, and Jyh-How Huang
Country:	USA
Date of Patent:	2013/10/15–2031/10/15
Abstract:	An operation method and a radio device for controlling a power switch of a radio based on moving speed. The radio device includes a speed estimator and an operator. The speed estimator is used for estimating the moving speed of the radio device, and the operator is used for comparing the moving speed of the radio device with a speed threshold value so as to turn on/off the power switch of the radio device. The power switch of the radio device can be controlled based on the moving speed so as to decrease the time the radio device stays on, thus reducing the power consumption of the radio device.

Patent:	System and Method for Time Synchronization
Inventors:	Polly Huang, Seng-Yong Lau, Ling-Jyh Chen, and Jyh-How Huang
Country:	USA
Date of Patent:	2013/02/26–2031/02/26
Abstract:	The present invention relates to a system, and a method for time synchronization with low power consumption and high accuracy. The system comprises a plurality of devices for time synchronization. Each device comprises a GPS receiver, a microprocessor, and an oscillator. The microprocessor generates a drift per second according to the difference between the PPS signal and the clock signal, and calibrates the clock signal constantly according to drift per second. The GPS receiver is turned off when the drift per second is obtained, and then is turned on after a pre-determined time period for updating the drift per second.
