Abstract: In a voice activity detector for an echo canceller, a difference is detected between a voltage at the receive path of a four-wire circuit of a hybrid transformer and a voltage at the transmit path of the four-wire circuit, the difference producing a first difference signal, and an echo return loss estimate is derived from the first difference signal. The first difference signal is compared with the loss estimate to produce a first binary signal. A difference is detected between the voltage at the transmit path and an output voltage of the echo canceller to produce a second difference signal, and an echo return loss enhancement estimate is derived from the second difference signal. The second difference signal is compared with the loss enhancement estimate to produce a second binary signal which, together with the first binary signal, forms one of a plurality of combinations of binary levels. An estimator of the echo canceller is enabled in response to apredetermined one of the combinations of binary levels, and is disabled in response to the other combinations.

Abstract: A process and apparatus are described for rapidly drying a wet, porous gel monolith of glass or ceramic, at subcritical tem-peratures without inducing any cracking of the gel. The wet gel is immersed in a liquid solvent in a chamber, and the liquid sol-vent is then heated and expelled from the chamber. Further heating, with or without the presence of a flowing inert gas, fully dries the wet gel. When an inert gas is used, the gas is delivered to the chamber with a controlled solvent partial vapor pressure, to correspondingly control the driving force for drying the gel.

Abstract: An undercarriage structure (12) for a track-type vehicle (10) has first and second spaced apart roller frame assemblies (14, 16) which are interconnected by a pivot shaft (18) and an equalizer bar (20). The first and second roller frame assemblies (14, 16) are so arranged with respect to the pivot shaft (18) and the equalizer bar (20) that the roller frame assemblies (14, 16 an substantially non-parallel to each other. This non-parallelism produces either "too-out" or "toe-in" of the roller frame assemblies (14, 16, which results in the endless track contacting the track rollers in different areas as the vehicle (10) travels in forward and then reverse directions. The wear life of the endless crack is thereby prolonged.

Abstract: The present invention relates to a battery charging unit. A battery charging unit is provided with a charge controlling unit which is designed to perform at least one of a rest mode operating function which stops charging for respective battery groups. A discharge mode is also provided which discharges electric power from the respective battery groups.  In addition a charge mode is provided for the respective battery groups.  The battery charging unit controls charging for the respective battery groups through the charge controlling unit while repeating at least two modes including the charging mode among the charging mode, rest mode and discharge mode in a predetermined time cycle and further performs a mutual control between the respective battery groups so that at least one battery group is placed in the rest mode in a predetermined sequence during the operation thereof.  As a result, the drawbacks of a conventional pulse type charging and burp charging unit, which are suitable for a quick charging but which requires a large instantaneous charging current which causes the size of the charger to increase are eliminated.
