20090309704 | Methods and Systems for RFID Reader Power Management - Methods, systems, and apparatuses for managing power consumed by an RFID reader are described. Such methods, systems and apparatuses can include, for example, controlling RFID reader power levels by detecting proximity to an RFID tagged object, by motion detection of RFID readers and tags. Using internal and/or external sensor modules, power management capabilities of the RFID reader are enhanced leading to less frequent recharging of the RFID reader. | 12-17-2009 |

20120229108 | Reduced power consumption for boost converter - A signal for controlling output voltage from the driver is modulated by the input signal to the driver, whereby the output voltage tracks the input signal, matching power to demand. The output storage capacitor can be reduced in size because the amount of energy that needs to be stored is reduced. In addition, feedback transistors are paired on the same substrate and cause opposite changes in response to changes in temperature, thereby automatically compensating for changes in temperature without the use of additional components. | 09-13-2012 |
20120313682 | Direct drive waveform generator - A high voltage waveform is generated that is similar to a low voltage input waveform. The high voltage waveform is a series of pulses that are applied directly to the device. An error signal controls the frequency, magnitude, and duration of the pulses. A feedback signal derived from the high voltage waveform is compared with the input waveform to produce the error signal. | 12-13-2012 |
20130200871 | DIRECT DRIVE WAVEFORM AMPLIFIER - A high voltage waveform is generated that is similar to a low voltage input waveform. The high voltage waveform is a series of pulses that are applied directly to the device. An error signal controls the frequency, magnitude, and duration of the pulses. A feedback signal derived from the high voltage waveform is compared with the input waveform to produce the error signal. | 08-08-2013 |

20080317389 | LIQUID DELIVERY POUCH AND ARTICLE COMPRISING THE SAME - A liquid delivery pouch comprises an outer liquid-impermeable wall and a liquid contained therein. The liquid-impermeable wall comprises at least one aperture having a diameter of from 200 μm to 500 μm. The at least one aperture is sealed by a sealing means to prevent the liquid to be released from said pouch prior to use. | 12-25-2008 |
