Granted: 2008-10-22
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a rotation of an optical axis is not coincident with an actual circumstance in the case of an extremely low speed including stopping and a high speed since the rotation of the optical axis is carried out only by an information from a steering device in a conventional variable light distribution head lamp system. SOLUTION: A speed signal is inputted to a control means of the variable light distribution head lamp system 1 and the control means 4 carries out a restriction of a function or an addition of the function against a light distribution change means 3 when a predetermined speed is detected at the speed signal. Therefore, a problem generated at the time of extremely low speed including stopping and a high speed is solved by also referring to a traveling speed.

Abstract: A deflectable tip catheter that is used in combination with a guidewire for delivery of an ablation element to target areas of a patient's vasculature. The deflectable tip catheter has a handle portion, an elongated shaft and a deflectable tip portion. A guidewire lumen extends through the elongated shaft and deflectable tip portion. A guidewire passes through the guidewire lumen and exits from a port in the distal end of the deflectable tip portion. The deflectable tip of the catheter is deflected by manipulation of the handle portion to direct the advancement of the guidewire as the guidewire is advanced out of the distal port. By using the deflectable tip portion to direct the advancement of the guidewire, the physician's ability to navigate sharp angles is greatly improved. The deflectable tip catheter is particularly suitable for delivering an ablation element to a pulmonary vein or pulmonary vein branch for performing circumferential ultrasound vein ablation to treat atrial fibrillation.

Abstract: Trench-gate field-effect transistors, for example power MOSFETs, are disclosed having trenched electrode configurations (11,23) that permit fast switching of the transistor, while also providing over-voltage protection for the gate dielectric (21) and facilitating manufacture. The gate electrode (11) comprising a semiconductor material of one conductivity type (n) is present in an upper part of a deeper insulated trench (20,21) that extends into a drain region (14,14a) of the transistor. A lower electrode (23) connected to a source (13,33) of the transistor is present in the lower part of the trench. This lower electrode (23) comprises a semiconductor material of opposite conductivity type (p) that adjoins the semiconductor material of the gate electrode (11) to form a p-n junction (31) between the gate electrode (11) and the lower electrode (23). The p-n junction (31) provides a protection diode (D) between the gate electrode (11) and the source (13,33). The gate electrode (11) is shielded from most of the drain region by the lower electrode (23), so reducing the gate-drain capacitance and improving the switching speed of the transistor.

Abstract: Provided are a digital signal encoding method and apparatus using a plurality of lookup tables. The method includes: preparing a plurality of lookup tables storing numbers of allocated bits for encoding frequency bands of an input signal according to a characteristic of the input signal in a predetermined number of addresses; dividing an input signal in the time domain into signals in predetermined frequency bands; calculating address values of the frequency bands; selecting one of the plurality of lookup tables according to the characteristic of the input signal; extracting numbers of allocated bits of addresses having the calculated address values from the selected lookup table with respect to the frequency bands and allocating the numbers of bits to the frequency bands; and generating a bitstream by quantizing the input signal according to the numbers of allocated bits. Bit amount control suitable for a characteristic of an input signal can be performed by extracting numbers of allocated bits of frequency bands from an optimal lookup table selected according to the characteristic of the input signal.
