  • Publication number: 20240069561
    Abstract: A robotic garden tool includes at least one sensor configured to generate signals associated with an object within an operating area. A first electronic processor of the robotic garden tool receives, from the at least one sensor, an obstacle signal associated with an obstacle located within the operating area. The first electronic processor determines a first location of the robotic garden tool at a time corresponding to when the first electronic processor received the obstacle signal. The first electronic processor determines a second location of the obstacle based on the obstacle signal and the first location of the garden tool. The first electronic processor generates mapping information of the operating area that includes a virtual boundary based on the second location of the obstacle. The first electronic processor controls the robotic garden tool in the operating area to remain outside of the virtual boundary based on the mapping information.

  • Publication number: 20150058111
    Abstract: 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.

  • Publication number: 20070014217
    Abstract: 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.
