Abstract: The present invention utilizes switching power amplifier technology to improve the performance of self-amplified speaker system. In contrast to analog Class A and Class AB amplifiers, the present invention utilizes a digital class D amplifier. Class D amplifiers are a pulse width modulated or digital switching amplifier configuration. The Class D amplifiers of the present invention includes 2-pole compensation feedback and power supply tracking that improves stability and total harmonic distortion over conventional power amplifiers. Class D amplifiers have an average electrical efficiency value of at least 65%. This level of electrical efficiency leads to reduction in the amount of power lost in the device or systems that result in heat generation.

Abstract: A method for contact-free testing of antennas applied to a material web, wherein the material web having the antennas is passed to a measurement device. The antennas are passed past an assigned measurement antenna arrangement of the measurement device in the region of the measurement device and the measurement antenna arrangement has a high-frequency signal Smess of a transmitter applied to it. This signal is correlated with a pre-determined working frequency fA of the antennas. The high-frequency signal Srück that returns from the measurement antenna arrangement is determined and compared with default values, and the adherence to production tolerances is determined by the comparison of the returning high-frequency signal Srück with the default values for each of the individual antennas.

This device is coupled upstream from electronic components to protect these components from damage. For example, in one embodiment, the overvoltage device is coupled to a fault circuit interrupter such as a GFCI, across the phase and neutral lines to protect components of the GFCI from an overvoltage condition. In one embodiment the overvoltage device is formed as an MOV physically coupled to a spark gap wherein the MOV and the spark gap are electrically coupled across the phase line and the neutral line in parallel.

Abstract: The invention relates to a method for diagnosing the degree of ageing of a catalyst arranged in the exhaust gas channel of an internal combustion engine, wherein the oxygen storage capacity of the catalyst is determined by means of the signals of a waste gas probe arranged upstream and downstream from the catalyst according to the OSC method when a rapid change occurs in the air/fuel ratios between a rich and lean mixture composition supplied to the internal combustion engine. The aim of the invention is to provide a method for determining the degree of ageing of a catalyst arranged in the exhaust gas channel of an internal combustion engine, wherein it is possible to ascertain the degree of ageing of a catalyst in a more accurate and more reliable manner, requiring little measurement effort.

The bar can be moved from a lower position to an upper position to form a barrier to keep children out of a tub. Alternatively, the device when it is in its extended position can be used to provide an additional support for a user when sitting in a tub, so that the user does not slide in the tub.

Abstract: New peptidomimetic inhibitors of retroviral proteases are in particular for human immunodeficiency virus (HIV) protease. These inhibitors include as the core structure a new diamiriodiol isostere of the dipeptide Phe-Pro having four stereogenic centers. The inhibitors have been shown to inhibit HIV-protease and can therefore be usefully employed as antivirals for post-exposure prophylaxis and as a therapy for viral infections by a retrovirus, in particular HIV. The syntheses processes of the isosteres and inhibitors are also described.
