Title: Sleep refreshed memory for neural network
Inventor: TAPANG CARLOS C
IPC: G06G7/60
Filed: 1989-09-29
Granted: 1994-03-22
Abstract: ABSTRACT A  method  and  apparatus  are  disclosed  for implementing  a  neural  network  having  a  sleep  mode during which capacitively stored synaptic connectivity weights are refreshed.   Each neuron outputs an analog activity level, represented in a preferred embodiment by  the  frequency  of  digital  pulses.    Feed-forward synaptic connection circuits couple the activity level outputs  of  first  level  neurons to inputs of second level  neurons,  and  feed-back  synaptic  connection circuits  couple  outputs  of  second  level  neurons  to inputs  of  first  level  neurons,  the  coupling  being weighted according to connectivity weights stored on respective  storage  capacitors  in  each  synaptic connection circuit.  The network learns according to a learning algorithm under which the connections in both directions between a particular first level neuron and a particular second level neuron are strengthened to the extent of concurrence of high activity levels in both the first and second level neurons, and weakened to the extent of concurrence of a high activity level in the second level neuron and a low activity level in the first level neuron.  The network is put to sleep by disconnecting all environmental inputs and providing a non-specific low activity level signal to each of the first  level  neurons.    This  causes  the  network  to randomly traverse its state space with low intensity resonant  firings,  each  state  being  visited  with  a probability  responsive  to  the  initial  connectivity weights of the connections which abut the second level neuron  representing  such  state.     Refresh  is accomplished  since  the  learning  algorithm  remains active during sleep.  Thus, the sleep refresh mechanism enhances the contrast in the connectivity terrain and strengthens connections that would otherwise wash out due to lack of visitation while the system is awake.  A   deep  sleep mechanism is also provided for preventing runaway strengthening of favored states,  and also to encourage Weber Law compliance.

Abstract: A retortable container has a wall of at least two co-formed laminae.   This wall is highly impermeable to fluids selected from the group consisting of oxygen and aromatic vapors.  The wall includes a first load-carrying lamina of a first plastic material.  This load-carrying lamina has been formed without mechanical hysteresis in the melt phase by a thermal pressure forming apparatus to cause strengthening with orientation of the load-carrying lamina in at least one axis but without memory of its pre-melt phase shape.  The wall also includes a second sealing lamina of a second plastic material.  This second sealing lamina is coextensive with the first load-carrying lamina.  Consequently, the container formed by the apparatus is retortable, i.e. it can withstand temperatures and pressures of a retort chamber without undergoing significant and permanent distortion.

Abstract: A mixer circuit with a conventional very high frequency circuit for the reception of color television bands I and III, which is connected dependent on the band and which is provided with an NPN transistor. The NPN transistor operates via a collector resistor onto a two circuit band filter. Moiré interferences in the band I region expanded for CATV are avoided by having the mixer current used to 0.3 to 0.6 mA via a counter coupling resistor disposed between base and hot end of the resistor 4. Thus the self-interference in band I is reduced by a value of about 60 dB. In case of band III operation the corresponding switching voltage is fed via a series connection of a diode 6 and a resistor 5 to the base and thus the base level is lifted up to higher mixing current, since in band III self-interferences cannot occur in the case of the presence of signals.

Title: High-efficiency air-conditioning system with high-volume air distribution
Inventor: KOPKO WILLIAM L
IPC: F24F13/072
Filed: 1998-05-15
Granted: 2001-10-11
Abstract: A system and method for providing conditioned air to the interior space of a building includes separate dehumidification and sensible cooling functions. The separate dehumidification allows for much higher supply air temperatures, preferably within about 10° F. to about 15° F. of the air temperature of the building space. Low-velocity air distribution through a ceiling plenum or a vent into the space allows for very low fan static pressures, which greatly reduces fan energy usage compared to conventional ducted systems. The low static pressures and high supply-air temperatures allow the use of existing drop ceiling construction with little modification. Optional return air channels between an inner glazing and an outer glazing of exterior windows can virtually eliminate heating loads at the building perimeter, which virtually eliminates the need for simultaneous heating and cooling. The result is a major improvement in energy efficiency and comfort while reducing installed cost of the system.

Title: Leveling control system for hydraulic elevator
Inventor: HOLLAND GORDON A
IPC: B66B1/50
Filed: 1990-04-25
Granted: 1999-09-14
Abstract: A hydraulic elevator includes level sensors for establishing dead zones of different sizes and for changing the dead zone while the car is stopped at a floor. A controller selects the size of the dead zone, for purposes of relevel operations, based upon elevator operating state (e. g. doors open or closed, time of day, time since last run) or other parameters (excess oil temperature, motor temperature, or excess motor starts). The controller also selects an effective hysteresis value either to return the car to floor level or to move the car to a position above floor level. In this manner, the controller maintains a small dead zone, and returns the car to level, when the doors are open. When the doors are closed, a larger dead zone is selected to reduce the frequency of relevel operations. Moreover, under certain conditions, the car is moved, during releveling, to a position above the landing, to further reduce the number of required relevel operations over time.
