  • Patent number: 8772197
    Abstract: One aspect of the present invention relates to reactive compositions and methods of use thereof, wherein a metal oxide cluster is used to connect a reactive group (or groups) to the surface of a substrate. In certain embodiments, the reactive group in the compositions decomposes organophosphate agents through nucleophilic hydrolysis. In certain embodiments, the reactive group in the compositions is bactericidal. Remarkably, the use of metal oxide clusters in the disclosed compositions and methods permits incorporation of higher quantities of nucleophilic and bactericidal groups without the difficulties associated with having to pretreat the substrate prior to its association with the reactive groups.

  • Patent number: 8706158
    Abstract: The present invention provides a mobile phone for authenticating Subscriber Identification Module (SIM) card and a SIM card authentication method adapted for the mobile phone. Once a SIM card is inserted into the mobile phone, the mobile phone acquires a phone number associated with the inserted SIM card and identifies whether the acquired phone number has been stored in the non-erasable programmable memory of the mobile phone. If yes, the user is legal and can use the mobile phone, if no, then the user is illegal and cannot use the mobile phone. Therefore, the mobile phone protects and hides stored information from the user.

  • Patent number: 8670528
    Abstract: A computerized method is implemented by a communication device for evaluating levels of importance of missed incoming calls. One or more reference parameters in relation to incoming calls received by the communication device are defined, a function for evaluating levels of importance of the missed incoming calls is formed using the one or more reference parameters. When an incoming call is received by the communication device, whether the received incoming call is missed is determined If the received incoming call is missed, the one or more reference parameters in relation to the received incoming call are obtained. A level of importance of the missed incoming call is evaluated by applying the obtained one or more reference parameters to the function.

  • Publication number: 20130338811
    Abstract: A matrix production system for a production line includes a plurality of processing units, a controller, and a plurality of detectors. Each processing unit covers a plurality of stations having the same or similar functions. Each station has a detector. The controller sets an initial flowchart during process of industrial production and a known first reference capacity for each station. A current number of workpieces at each station is detected. The controller compares the current number with the first reference capacity to determine an overburdened station or otherwise and then analyzes a running state of overburdened station determined as being overburdened to establish a malfunctioning station, and if malfunctioning, switches the flow of workpieces from the malfunctioning station to a station with the greatest amount of available or free capacity.

  • Publication number: 20130330005
    Abstract: A character recognition method to apply one or more user-controlled definitions to scanned writing is implemented by an electronic device. The electronic device includes an image capturing device where a recognition rule is set for recognizing a type of a sequential code according to an arrangement rule of characters of the type of sequential codes. A first sequential code is extracted from a captured image of an object having a sequential code and when the first sequential code does not match with the recognition rule, the first sequential code is corrected according to the preset recognition rule to obtain a second sequential code for matching with the recognition rule.

  • Publication number: 20120066532
    Abstract: An electronic device includes a dynamic memory, a static memory, a detection unit, a copy unit and a set unit. The dynamic memory stores an interrupt monitoring program. The interrupt monitoring program monitors whether an interrupt request is generated, and generates an interrupt signal when the interrupt request is generated. The detection unit detects whether the electronic device needs to enter a sleep mode, and generates a detection signal if the electronic device needs to enter the sleep mode. The copy unit copies the interrupt monitoring program from the dynamic memory to the static memory in response to the detection signal, and runs the interrupt monitoring program in the static memory for monitoring whether an interrupt signal is generated. The set unit sets the dynamic memory into a self-refresh mode in response to the detection signal.
