20110057825 | Diode smart track - Systems and methods to achieve a logarithmic digital-to-analog converter (DAC), which is easy to be implemented, and requiring reduced chip space have been disclosed. The logarithmic DAC is created by a simple and easy to scale linear DAC, which is linearly scaling a predefined voltage range. The output voltage of the linear DAC is converted to a logarithmic current value directly by the voltage-current characteristic of an integrated diode. | 03-10-2011 |
20130221947 | Battery Wake-Up - Circuits and methods for fast detection of a low voltage in the range of few μVolts have been achieved. In a preferred embodiment the low voltage represents a current via a shunt resistor and the circuit is used to generate a digital wake-up signal. In regard of the wake-up application the circuit invented is activated periodically and in case of a certain level of the voltage drop, e.g. 50 μV, at the shunt resistor. The time required for a measurement of the voltage drop is inclusive calibration and integration time far below 1 ms. It is obvious that the circuit invented can be used for any measurements of very small voltages. | 08-29-2013 |

20090183628 | DUAL SIDED AND DUAL PROCESS BANDOLIER - A method of making bullets on a progressive die wherein the progressive dies acts on a work piece having an elongated body with blanks at each end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die forms each blank into a bullet, effectively doubling the output of the progressive die relative to a progressive die that acts upon a work piece that supports, or is, a single blank. | 07-23-2009 |
20100170321 | BANDOLIER WITH LATERALLY OFFSET AND SPACED WORK PIECE - A method of operating a progressive die wherein the progressive die acts on a work piece having an elongated body with a blank at one end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die acts on each blank. | 07-08-2010 |
20120137861 | BANDOLIER WITH LATERALLY OFFSET AND SPACED WORK PIECE - A method of operating a progressive die wherein the progressive die acts on a work piece having an elongated body with a blank at one end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die acts on each blank. | 06-07-2012 |

20110104279 | HEALING POWDER AND METHOD OF USE THEREOF - A method for treating wounds, comprising providing a dry powder mixture, which when partially hydrated, forms a gel having an osmotic pressure sufficient to achieve and maintain antiseptic conditions in hydrated portions of the gel, the gelled portion comprising a biocompatible polymer, the dry powder being readily wettable by wound secretions; and applying the dry powder to a wound having wound secretions in sufficient excess to produce a self-adherent gel cake having a dry powder surface. The administration may be repeated by administration of the dry powder while wound healing progresses. | 05-05-2011 |
20130171093 | HEALING POWDER AND METHOD OF USE THEREOF - A wound healing powder, comprising a sugar selected from the group consisting of one or more pharmaceutically acceptable monosaccharides and disaccharides, in an amount of at least 25% by weight of the powder mixture; and an absorbent agent which forms a bioabsorbable biocompatible matrix with wound secretions, comprising a polymer formed of one or more of saccharide or saccharide derivative monomers and lactic acid monomers, in an amount of at least 25% by weight of the powder mixture. | 07-04-2013 |
