| 20120123713 | Control of Delivery of Current Through One or More Discharge Lamps - Method to identify a current drawn by a fluorescent lamp in a circuit. Methods include receiving a voltage supplied to a fluorescent lamp drawing a current in response to the voltage, digitally sampling the voltage at a sampling frequency and associating a first time stamp with a voltage value representing one of a maximum or minimum value in observed voltage, receiving the current after receiving the voltage, digitally sampling the current at the sampling frequency and associating multiple second time stamps with a corresponding multiple current values, identifying a second time stamp, a difference between the first time stamp and the second time stamp being within a threshold, and identifying a current value associated with the second time stamp as the current drawn by the fluorescent lamp. | 05-17-2012 |
| 20080253014 | Magnetic disk controller and method - Among other disclosed subject matter, a magnetic disk controller can include an index detecting unit to detect an index of the magnetic disk, an error check code generating unit to, after the index detecting unit detects the index, generate a first error check code for first write data based on the first write data and a first physical address of a first sector subsequent to the detected index, and a writing control unit to cause the first error check code generated by the error check code generating unit, the first write data and the first physical address to be written into a second sector subsequent to the first sector. | 10-16-2008 |
