Patent KR-20070091650-A (KR)
Title: Brightness sensor
Inventor: RUDIGER GERFRIED
IPC: H05B44/00
Filed: 2005-12-01
Abstract: An electroluminescent (EL) element (10) is connected to the power supply and is intermittently operated as a lighting device and as a brightness sensor. For this purpose, the processing unit (15) induces the controlled AC voltage source (20) to reduce the voltage for a short period. The current intensity is measured by current measuring devices (14) and the corresponding measuring signal is digitized using the analog/digital converter (A/D). A processing unit (15) uses the signal and the effective voltage to determine, by means of empirical calibration data stored in the memory (16) or by using a calibration function, the brightness, i.e. the luminance of the light that is incident on the EL element (10). The processing unit (15) associates, using desired values stored in the memory (16), the detected brightness with an operating voltage level which ensures the desired emission brightness of the EL element (10) when operated as a lighting device. Optionally, the determined operating voltage is corrected in order to take into consideration any brightness loss of the EL element (10) caused by aging. The optionally corrected value is output via the control channel (21) as the desired operating voltage and is maintained by the power supply unit (20) until the next measuring interval.

Title: Method of making a planar double-gated transistor
Inventor: ORLOWSKI MARIUS K
IPC: H01L29/78
Filed: 2005-12-14
Abstract: A silicon layer (16) interposed between the top silicon nitride layer (SiN) (20) and a silicon germanium layer (SiGe) (14) which in turn is over a thick oxide (BOX) (12) is selectively etched to leave a stack with a width that sets the gate length. A sidewall insulating layer (28) is formed on the SiGe layer (14) leaving the sidewall of the Si (16) layer exposed. Silicon (30, 32) is epitaxially grown from the exposed silicon sidewall (16) to form in-situ-doped silicon source/drain regions (30, 32). The nitride layer (20) is removed using the source/drain regions (30) as a boundary for an upper gate location. The source/drain regions (30, 32) are coated with a dielectric (36). The SiGe layer (14) is removed to provide a lower gate location (46). Both the upper and lower gate locations (46) are filled with metal to form upper and lower gates (50) for the transistor (10).

Title: Emulsion whisk
Inventor: SOKOLOFF JARED
IPC: A47J43/10
Filed: 2006-03-23
Abstract: A novel type of whisk for dispensing ingredients from the handle of the whisk is a useful and efficient way for emulsifying ingredients, and creating sauces, batters, dressings and the like. A whisk which allows a food preparer to dispense ingredients directly through the whisk itself without having to stop and pour ingredients and suspend the whisking process leads to a better and more consistent emulsion, and greatly reduces awkward and messy two handed cooking. An emulsion whisk includes means for housing ingredients in the inner chamber of the handle and means for dispensing ingredients from the handle directly into a mixing bowl. The whisk may be a singular structure or may be detachable in two-piece units for swapping different types of whisk elements such as balloon whisks, rotary whisks, ball whisks, flat whisks, trimmed whisks and twirl whisks.
