Tire Valve And Pressure Gauge
US Patent:
5103670, Apr 14, 1992
Filed:
Jul 13, 1990
Appl. No.:
7/553183
Inventors:
Min-Yu Wu - San Jose CA
Andrew H. Wu - San Jose CA
Andrew H. Wu - San Jose CA
International Classification:
B60C 2302, G01L 706
US Classification:
731468
Abstract:
The combination tire valve and pressure gauge of the present invention is formed to be substantially the same size as current tire valve stems, such that it may be used as a replacement part therefore. The device includes a pressure sensitive bellows disposed within the stem, the movement of which is counteracted by a calibrated spring. Movements of the bellows, caused by changes in the tire pressure, are mechanically translated to a rotary motion of a pressure indicator. A window is formed in the tire stem to permit viewing of the pressure indicator, whereby different numerals corresponding to different tire pressures become visible in the window upon rotation of the indicator which is caused by movement of the bellows. An air channel is formed through the device to permit air to be pumped into the tire. A rotary indicator having an internal spiral groove rotates upon a driving rod formed with projecting driving pin members that project into the spiral groove to cause the rotation of the indicator.
Short Circuit Current Ratcheting In Switch Mode Dc/Dc Voltage Regulators
US Patent:
7714558, May 11, 2010
Filed:
Aug 30, 2005
Appl. No.:
11/216276
Inventors:
Andrew Wu - San Jose CA, US
Assignee:
Monolithic Power Systems, Inc. - San Jose CA
International Classification:
G05F 1/00
US Classification:
323284
Abstract:
In an embodiment, an apparatus is provided. The apparatus includes a high side pass device. The apparatus also includes a low side pass device coupled in series to the high side pass device. The apparatus further includes a control module coupled to the high side pass device and the low side pass device. The control module is coupled to the high side pass device and the low side pass device to control the high side pass device and the low side pass device. Additionally, the apparatus includes a first resistor coupled in series with the high side pass device and the low side pass device. Furthermore, the apparatus includes a first comparator coupled in parallel with the first resistor. The first comparator has a threshold voltage input differential corresponding to a first current limit, and an output of the first comparator is coupled to the control module. Moreover, the apparatus includes a second comparator coupled to sense current of the high side pass device as a voltage. The second comparator has a threshold voltage input differential corresponding to a second current limit.
