Publication number: 20150058111Abstract: A system and method provided for recruiting new membership through value sending from existing members. The value can be coupons, discount offers, membership points or payment vouchers in physical and/or electronic formats. The method is an active way to recruit new members through the social network of existing members. Once a member in the system sends value from their account to the non-members by simply entering his/her mobile phone number as identification of the receiver, the receiver will receive the notification through short message service (SMS) or similar service of the value received. The receiver uses his/her mobile number together with the password disclosed within the notification message for redeeming the received value at the point of purchase in the corresponding public facing business. In addition, the receiver can update his membership details through a registration webpage on the internet.Type: ApplicationFiled: June 19, 2012Publication date: February 26, 2015Applicant: Value Exchange International LimitedInventors: Chi Ho Lee, Chi Ming Darius Lau, King Yiu Fung

Publication number: 20070014217Abstract: A method of determining an optimum recording power with respect to a rewritable optical recording medium with multiple layers. The method includes the operations of writing a recording signal to an unrecorded area of a power calibration area (PCA) of the rewritable optical recording medium using a predetermined recording power, and measuring characteristics of the recording signal, determining whether the measured recording signal characteristics have a saturation area, computing a recording power at a saturation point of the recording signal characteristics when the recording signal characteristics have the saturation area, and determining an optimum recording power by multiplying the recording power at the saturation point by a predetermined value. An optimum recording power is determined by using the saturation point of the recording signal characteristic curve such that optimum recording power can be accurately obtained when the optimum recording power is in the saturation area.Type: ApplicationFiled: July 13, 2006Publication date: January 18, 2007Applicant: Samsung Electronics Co., Ltd.Inventors: Kang-uk Cho, Shuichi Tasaka, Wook-yeon Hwang, Yong-jin Ahn, Jong-kyu Kim, Chi-ho Lee

Publication number: 20060077846Abstract: A method of erasing a power calibration area (PCA) for determining optimum power, including applying a command for recording data, detecting a non-recorded PCA area for performing optimum power control (OPC), and when all the PCA area is used and no non-recorded PCA area is detected, performing erasing of the PCA area at least twice. Accordingly, since the PCA area is erased at least twice, reliability of the optimum recording power determined by performing the OPC is much improved.Type: ApplicationFiled: July 14, 2005Publication date: April 13, 2006Applicant: Samsung Electronics Co., Ltd.Inventors: Jin-woo Yu, Byung-hyun Min, Chi-ho Lee, Kang-uk Cho
