20080291751 | SCR MATRIX STORAGE DEVICE - One of the simplest forms of data storage devices is the diode array storage device. However, a problem with diode array storage devices is that as the size of the array increases, the number of non-addressed diodes connected between a given selected row or column of the array and the non-addressed columns or rows of the array, respectively, also becomes very large. While the leakage current through any one non-addressed diode on the selected row or column will have little impact on the operation of the device, the cumulative leakage through multiple thousands of non-addressed diodes can become significant. This aggregate leakage current can become great enough that the output voltage can be shifted such that the threshold for distinguishing between a one state and a zero state of the addressed diode location can become obscured and can result in a misreading of the addressed diode location. The present invention is a means to manage the leakage currents in a diode array storage device. This is accomplished by actively changing the forward voltage of the diodes in the storage array such that a diode connected to the selected row line but that is not connected to the selected column line is in its high impedance state and a diode connected to the selected column line but that is not connected to the selected row line is in its high impedance state; only a diode that is connected to both the selected row line and the selected column line will switch to its low impedance state. The present invention is an enhancement to all types of arrays of diodes or arrays of other nonlinear conducting elements including: storage devices, programmable logic devices, display arrays, sensor arrays, and many others. | 11-27-2008 |

20120096331 | Multiple sector parallel access memory array with error correction - The present invention is a method for accessing more than one block of correctable information at a time when it is most efficient to access more bits of information at a time on a given dimension, for example from a multiple bit per cell (MLC) memory element, than the error correction algorithm can correct. Since it may be more efficient to access more bits of information at a time on a given dimension than the error correction algorithm can correct, that access is performed in this most efficient way, but the information is divided into correctable blocks within this information such that the error correction algorithm can still compensate for a serious fault along a given dimension. Furthermore, the present invention can be employed even when the number of bits retrieved along a given dimension is less than the number of correctable bits when it is desired to protect against a given number of faults which could, in total, exceed the number of correctable bits. | 04-19-2012 |
20130015636 | Collapsible trailer for compact parking - The present invention is a foldable trailer that drops close to the ground and shortens in length when folded such that it can be parked below the vehicle that towed it. In this way, the trailer and vehicle can both be parked in the same, single space. During towing, the trailer is locked into its opened towing position and the weight of the device being towed helps to maintain the opened position. The trailer can be folded into its closed parking position while still hitched to the vehicle by which it was towed to facilitate moving it into its parking space before being unhitched. Once unhitched, the trailer will be parallel to and close to the ground such that the vehicle can then park above it. By sharing the same place, parking fees are reduced and preparation time (time spent in parking arrangements) is shortened. | 01-17-2013 |
20130024064 | Trailer backing up device and table based method - The present invention, when used to backed-up a trailer, indicates which direction and how much to steer to steer.

Servomechanisms can be incorporated to enable the vehicle to steer itself while the driver indicates the direction travel desired for the trailer, otherwise a pointer would indicate, for the current position of the vehicle's steering wheel, the predicted direction of the trailer. To back-up the trailer, the driver would turn the vehicle's wheel such that the pointer is kept pointing in the direction of the intended trailer destination. Furthermore, the present invention will indicated the projected directions of the left and right limits to control the direction of the trailer, particularly when maneuvering complex paths. | 01-24-2013 |
