  • Patent number: 10742995
    Abstract: An encoding system includes a prediction mode decision unit and an encoding unit. The prediction mode decision unit is configured to receive a target image and decide an optimized mode by applying rate-distortion optimization (RDO) to n (n is a natural number) modes of the target image. The encoding unit is configured to encode the target image according to the decided mode. The prediction mode decision unit includes a distortion calculation unit configured to calculate distortion by mean squared error (MSE) calculation between the target image and the n modes, a Lagrangian multiplier calculation unit configured to calculate a Lagrangian multiplier based on multi-scale structural similarity (MS-SSIM) calculation, and a bitrate calculation unit configured to calculate a bit rate of the n modes.

  • Patent number: 8159269
    Abstract: A single terminal is used to configure an integrated circuit into one of three states. A circuit within the integrated circuit is coupled to the terminal and determines whether the terminal: 1) is coupled by a low impedance to a voltage source, or 2) is coupled by a medium impedance to the voltage source, or 3) is floating or substantially floating. The circuit asserts a first digital logic signal when the circuit determines that the terminal is coupled by the low impedance to the voltage source. The circuit asserts a second digital logic signal when the circuit determines that the terminal is coupled by the medium impedance to the voltage source. The circuit asserts a third digital logic signal when the circuit determines that the terminal is floating or substantially floating. The terminal and circuit are particular suited for use in a Power Management Unit (PMU) Integrated Circuit.

  • Patent number: 6742284
    Abstract: The invention is a drying system and a method for its use, the drying system having a container containing a product to be dried and a dryer. The dryer includes an inlet for providing the drying air, a drying air pathway, and a furnace for heating the drying air. The drying air flows through a supply route to the container, where the drying air dries the product and is converted into a return air. The return air flows through a return route back to the dryer. The return air flows through a return air pathway and a heat exchanger which intersects the return air pathway and the drying air pathway. The heat exchanger transfers heat from the return air to the drying air. The return air is exhausted through an outlet. In a preferred embodiment, the container is a tobacco barn and the product is tobacco.

  • Patent number: 6209223
    Abstract: This invention is a new, energy efficient, environmentally clean grain drying system which consists of two main parts: a hot drying air generator and a modular, portable drying bin. One novel aspect of the air generator is the introduction of a heat pipe design which enhances the efficiency of a dehumidifier heat pump, making its use economically feasible, especially for humid climates. Another novel aspect is the use of advanced burners incorporating antipollution devices. The hot air generator can operate on many sources of energy such as electricity; gasoline; diesel; biomass such as wood, charcoal, or rice husks; or even solar energy. The modular bin is made of several modules which can be disassembled, transported, and reassembled with great ease. The bin design also creates a very low air pressure drop, allowing substantial savings on blower energy. The complete system will offer great benefits for developing countries that are producers of rice, especially for those with humid climates.

  • Patent number: 5921315
    Abstract: A heat pipe heat exchanger is provided in the form of a serpentine heat pipe that does not have the ends of the individual tubes manifolded to one another via a straight pipe or via any other common connector. Instead, it has been discovered that heat pipes connected via U-bends to form a continuous coil function adequately. The serpentine heat pipe may include integral condenser and evaporator portions separated by a divider to form a one-slab heat exchanger, or separate evaporator and condenser coils connected to one another by vapor and return lines to form a two-section heat pipe. The heat pipe heat exchanger may be formed in a continuous closed-loop pipe so that the heat exchanger can operate with or without the aid of gravitational effects.

A method of producing a serpentine heat pipe includes providing a plurality of U-shaped tubes which are interconnected to form a single serpentine heat pipe, one of the tubes having an open end, and inserting sufficient refrigerant in the one tube to allow each of the tubes to function as a separate heat pipe. The serpentine heat pipe heat exchanger may be used to increase the dehumidification capacity of an air conditioner.
