  • Publication number: 20140002384
    Abstract: A method for inserting images includes the following steps. Sense a touch trace of a user forming a closed loop having an enclosed region and generating a trigger signal if the touch trace forms a closed loop having an enclosed region. Sense handwritten touch input by the user within the enclosed region and generating signals associated with the user's handwritten touch input. Display the closed loop and the sensed handwritten touch input of the user. Determine whether the sensed handwritten touch input associates with an image inserting command in response to the trigger signal. Retrieve an image selected by the user from a storage unit, if the sensed handwritten touch input associates with an image inserting command. And display the selected image within the an enclosed region of the closed loop. An electronic device using the method is also provided.

  • Publication number: 20140006920
    Abstract: An electronic device used for writing memos includes a storage unit, a display unit, a touch input unit, and a processor. The storage unit is used for storing an electronic calendar and a memo file written by a user. The touch input unit senses touch input of handwritten content on the displayed electronic calendar by the user and generating signals associated with the user's touch input, and recognizes handwritten content of the user according to the generating signals. The processor includes an identification module and a memo adding module. The identification module determines a date associated to the created handwritten content according to the generated signals. The memo adding module automatically adds the recognized handwritten content to the memo file stored in the storage unit of the determined date. A method for writing memos is also described.

  • Publication number: 20130276443
    Abstract: A method for controlling an exhaust-braking engine maneuver includes driving a compressor by a turbine so that the compressor receives and compresses an intake stream of fluid to produce a stream of compressed fluid. The method also includes receiving a stream of engine working fluid that includes the stream of compressed fluid, and discharging, to an exhaust system, an exhaust stream comprising the stream of engine working fluid. A stream of scavenged exhaust fluid comprising at least a portion of the exhaust stream is received, and work is extracted from the stream of scavenged exhaust fluid by the turbine to drive the compressor. The variable turbine nozzle and an intake throttle valve are modulated so as to satisfy one or more turbine control criterion and one or more compressor control criterion.

  • Publication number: 20130269654
    Abstract: A method of controlling a diesel engine includes sensing a speed of the diesel engine, and closing a throttle of the diesel engine when the sensed speed of the diesel engine is equal to or greater than a maximum allowable engine speed to prevent oxygen from entering an intake manifold of the diesel engine, thereby preventing combustion and stopping the operation of the diesel engine. An Exhaust Gas Recirculation (EGR) valve is actuated to regulate circulation of exhaust gas from the diesel engine through the intake manifold to control pressure within the intake manifold to prevent damage to other engine components from excessive positive or negative pressure.

  • Publication number: 20130060829
    Abstract: A method and apparatus for additive range reduction are disclosed. A constant may be pre-stored in a look-up table (LUT), and at least one section of the constant may be retrieved from the LUT for generating a product of an input argument and the constant such that a precision of the product may be controlled in any granularity. For a trigonometric function, 2/? is stored in the LUT, and at least one section of 2/? may be retrieved from the LUT. The argument is multiplied with the retrieved sections of 2/?. The retrieved sections are determined to correctly generate the two least significant bits (LSBs) of an integer portion and a scalable number of most significant bits of the multiplication result. An output of the trigonometric function is generated for the argument with a fractional portion of the multiplication result based on two LSBs of the integer portion of the multiplication result.

  • Patent number: 8387384
    Abstract: An intake control system comprises an estimation module and a turbocharger control module. The estimation module receives one of a first pressure within an intake manifold measured by a manifold pressure sensor and a second pressure measured by a pressure sensor at a location between a compressed air charge cooler and a throttle valve. The estimation module estimates the other one of the first and second pressures based on the received one of the first and second pressures. The turbocharger control module controls output of a turbocharger based on the estimate of the other one of the first and second pressures.
