Abstract: The present invention provides a pharmaceutical formulation comprising a compartment containing a rennin inhibitor as a pharmacologically active ingredient, and a compartment having an angiotensin-II-receptor blocker as a pharmacologically active ingredient. One of the compartments is an immediate-release compartment and the other one is an extended-release compartment. Since the disclosed formulation delivers the rennin inhibitor and angiotensin-II-receptor blocker at a specific delivery rate at a different time. It has an advantage in reducing the concern about side effects, improving drug effects, and simplifying the instructions for use of the drug. In addition, the formulation can pharmacologically, clinically, scientifically, and economically achieve more useful effects than the complex prescription case of taking the ingredients separately or each at once, in preventing and treating metabolic syndrome, cardiovascular disease and renal disease.

Abstract: A power supply having a maximum power point tracking function that controls power switching so that a detected power value is within a reference range having a maximum power point in a predetermined current-voltage curve includes: a converter section switching input power and converting the switched input power into predetermined DC power; and a maximum power point tracking section detecting a power value determined according to a switching operation of the converter section among power values included in a predetermined power-voltage curve, and controlling the switching operation of the converter section so that the detected power value is located within a predetermined reference range having a maximum power value among the power values included in the power-voltage curve.

Abstract: The present invention features a battery pack, that is provided to supply electricity to a variety of electric parts, such as a drive motor, installed in an environment friendly electric vehicle such as a fuel cell vehicle or a hybrid electric vehicle. Preferably, the battery pack is configured to stack cell assemblies. Each cell assembly includes a cell case. The cell case includes windows in opposite surfaces thereof such that unit cells are exposed, and recesses in opposite long lateral faces thereof such that the windows communicate with an outside. The windows and the recesses define cooling passages between the stacked cell assemblies.

Abstract: In accordance with the present invention, a power converter transformer for suppressing conduction EMI (ElectroMagnetic Interference) includes a primary winding positioned at a primary side; a secondary winding positioned at a second side and coupled with the primary winding; a parasitic capacitor connected between one end of the primary winding and one end of the secondary winding; a switching unit connected to the other end of the primary winding; a Y-capacitor connected between the switching unit and a ground terminal; an auxiliary winding positioned at the secondary side and coupled with the secondary winding; and an auxiliary capacitor connected between the one end of the primary winding and the auxiliary winding.

Abstract: A mobile device has a first object, a second object, and a hinge device to slide open and close the second object with respect to the first object. The hinge device has a sliding unit that is slidable with respect to a first object, and a rotary unit that is rotatable with respect to the sliding unit, and engaged with the second object. The hinge device requires a relatively smaller space to be installed in the mobile apparatus so that the mobile apparatus can be smaller. Furthermore, there is no installation line for the hinge device so that the aesthetic design of the mobile apparatus is more refined.

Abstract: A hydraulic system for construction equipment having a float function is provided, which can perform ground leveling as making a boom descend due to its own weight without using hydraulic fluid that is discharged from a hydraulic pump.

Abstract: Methods and apparatus for self testing a multiband voltage controlled oscillator (VCO) are disclosed. A tuning voltage of the VCO is adjusted where the output of the VCO does not affect the input to the VCO. Frequency bands in the VCO are selected. Output frequencies of the VCO are measured.

Abstract: A method for self testing a multiband voltage controlled oscillator (VCO) is described. A first frequency band in a VCO is selected. An N value is selected for a frequency divider that produces a tuning voltage for the VCO that is between a low tuning voltage limit and a high tuning voltage limit for the VCO. The N value is adjusted in one direction until the tuning voltage reaches one of the tuning voltage limits. This N value at the tuning voltage is a first limit value. The frequency bands are switched from the first frequency band to a second frequency band that is adjacent to the first frequency band.
