Granted: 1996-11-19
Abstract: A method for modernizing the control system of a bank of elevators, wherein in a first stage, the elevators are connected to work under elevator-specific computers controlled by a control system comprising a group controller and communicating  by  means of at  least one serial  communication bus.  The connection is effected using passive adapters between the computers and the old elevator controller. For completing the modernization process of the individual elevators, the elevator-specific functions are modernized by replacing their oldfunctions with functional modules and/or by adding functional modules performingnew functions. The  functional modules are  connected to the  elevator  computeron a serial bus, one at a time, for gradually replacing the old elevator circuits connectable to a serial communication bus.

Title: Absorbent composites and absorbent articles containing same
Inventor: BYERLY SHANNON KATHLEEN
IPC: A61F13/15
Filed: 1992-08-26
Granted: 2002-10-08
Abstract: When a superabsorbent material is to be incorporated into an absorbent composite in a relatively high concentration, it is necessary to carefully choose the superabsorbent material.     Properties of the superabsorbent material to be considered are total Absorbent Capacity, resistance to Deformation Under Load, the ability of the superabsorbent material to absorb while under a restraining force, and the ability of the superabsorbent material to wick fluids away from the insult area. By quantifying these characteristics of a superabsorbent material, Applicants are able to predict which superabsorbent materials are suited for use in absorbent composites comprising a relatively high concentration of superabsorbent material.

Abstract: This invention is intended to provide a continuous parts feeder capable of continuously feeding parts to a metal mold installed in a pressure machine such as a press.     An actual example of this invention consists of a parts transport pipe (40) that uses compressed air to feed parts, magazines (42, 44) that feed parts sequentially to this parts transfer pipe (40) with compressed air, and a coupling device (46) that can selectively switch the entrance of the parts transport pipe(40) between the outlets of at least two magazines (42, 44). It will also be equipped with an auxiliary compressed air supply device (57) that supplies auxiliary compressed air to the inside of the parts transport pipe according to information from the parts detector (56) which determines whether there are or are not parts inside the parts transport pipe (40), so that the transport of parts inside the parts transport pipe is performed smoothly. The coupling device (46) is automatically controlled by the automatic control device (48).

Title: P-i-n photodiodes with transparent conductive contacts
Inventor: BERGER PAUL RAYMOND
IPC: H01L31/0216
Filed: 1993-01-15
Granted: 1996-03-12
Abstract: This invention pertains to a p-i-n In0.53 Ga0.47 As photodiode having an optically transparent composite top electrode consisting of a thin semitransparent metal layer from 10 to 40 nm thick and a transparent cadmium tin oxide (CTO) layer from 90 to 600 nm thick. The metal layer makes a non-alloyed ohmic contact to the semiconductor surface, acts as a barrier between the semiconductor and the CTO preventing oxidation of the semiconductor from the O2 in the plasma during reactive magnetron sputtering of the CTO layer, and prevents formation of a p-n junction between the semiconductor and CTO. The CTO functions as the n or p contact, an optical window and an anti-reflection coating. The top electrode also avoids shadowing of the active layer by the top electrode, thus allowing greater collection of incident light. Since the top electrode is non-alloyed, inter diffusion into the i-region is not relevant, which avoids an increased dark current.

Inventor: ROY DONALD
IPC: F24F12/00
Filed: 1993-07-06
Granted: 1996-03-12
Abstract: The present ventilating system is used for homes and buildings located in cold climate areas.  The system includes a heat exchanger for extracting heat from the inside air discharged to the exterior and transferring said heat to the outside air admitted into the building.  Blowers circulate air through the two paths of the heat exchanger and a motorized damper on the outside air path closes or opens the same.  An integrated circuit and the following sensors serve to operate the system as follows:  sensors detect the concentration of air contaminants, the humidity and the negative pressure of the air inside the building, while an outside air temperature sensor is also provided.  When the level of air contaminants is above an adjustable preset level,  the system operates in an inside air upgrading mode, namely air is circulated in both paths of the air exchanger; the same mode is used where humidity level is found to be excessive.  When negative air pressure is detected, the system is operated to admit only outside air within the building,  and if the outside air temperature is below a preset level, the system is operated in a heat exchanger de-icing mode for an adjusted time after each adjusted total time of system operation in either humidity or air-upgrading operating mode.

Title: Adaptive video encoder for two-layer encoding of video signals on atm (asynchronous transfer mode) networks
Inventor: HORNE CASPAR
IPC: H04N21/236
Filed: 1993-10-13
Granted: 1999-07-13
Abstract: The quality of video images received at the remote end of an ATM network capable of transmitting data at high and low priorities is greatly improved at high cell loss levels by employing a two-layered video encoding technique that adapts the method for encoding information transmitted in the low-priority digital information stream to the rate of cell loss on the network so that compression efficiency and image quality are high when the network load is low and resiliency to cell loss is high when the network load is high. The encoder adapts its encoding method in response to a cell loss information signal generated by the remote decoder by selecting the prediction mode used to encode the low-priority digital information stream, and by changing the frequency at which slice-start synchronization codes are placed within the low-priority digital information stream (FIG. 1).

Abstract: In a method for generating a transmitting wave, a power supply voltage to be supplied to a transmission power amplifier is detected by a voltage detector, and a modulating signal is controlled so that a peak value of a modulated wave is lowered in accordance with a reduced amount of the power supply voltage. Since the peak value of the modulated wave input to the power amplifier is lowered, it is possible to obtain a transmitting wave without a distortion of the waveform or an increased bandwidth, even when the reduction in the power supply voltage involves the lowering of the driving capability of the power amplifier.
