The invention provides a controller for a memory having at least one memory cell, that involves a higher cost for writing than for reading. The memory cell is allocated to a first address information and adapted to store memory data. The memory controller of the invention comprises a register. A write controller connected with said register and said memory is adapted to receive a write request comprising said first address information and first write data allocated thereto, ascertain whether sai...

A Flash memory system includes N flash devices, where N is an integer, each flash device having a flash device interface consisting of a control signal line, a R/B signal line, and a I/O signal line, and wherein each flash device has an operating speed of s. A logic block is connected to each flash device interface, and is further connected to a controller which whose interfaces also has a control signal line, a R/B signal line, and a I/O signal line, so that controller operates at an operating ...

A tow pin attachment for tow trucks. The attachment can be removably connected to a tow truck. A tow pin carried by the attachment is movable between operative and inoperative positions. Means on the tow pin lock the attachment to the truck when the tow pin is in operative position.

The specification discloses a heap memory management system in which software streams remove and replace blocks of heap memory from the heap pile, managed in a linked list fashion, in a last-in/first-out fashion at the top of the list. A hardware device returns blocks of heap memory, and this return is to the end or bottom of the linked list. In this way, software streams may remove and return blocks of heap memory simultaneously with hardware devices returning blocks of heap memory.

A tow truck conveyor system comprising a plurality of tow trucks, each of which has a tow pin extending downwardly through a slot in a floor to engage a conveyor. Each tow truck has a movable front bumper that is operatively connected to the tow pin to raise the tow pin out of engagement with the conveyor upon encountering an obstacle or a preceding tow truck. Each tow truck further includes a rear bumper that is adapted to be held in its rearward position when the front bumper is moved rearward...

In accordance with an illustrative embodiment of the present invention, a well perforation cleaning tool includes a fluidic oscillator that creates pressure changes which induce cyclical stresses in the damaged skins of the perforations and causes the skins to disintegrate in order to improve the productivity of the well. Cylindrical filter tubes having a plurality of sets of slots are adjustably mounted at the upper and lower ends of the tool to provide resistances which confine the pressure ch...

Managing memory includes subdividing the memory into a first set of blocks corresponding to a first size and a second set of blocks corresponding to a second size that is greater than said first size, in response to a request for an amount of memory that is less than or equal to the first size, providing one of the first set of blocks, and, in response to a request for an amount of memory that is greater than the first size and less than or equal to the second size, providing one of the second s...

A conveyor for a vehicle washing system. The conveyor includes an endless chain located above grade level so that both the conveying path of the chain and the return path move in a common horizontal plane. A series of roller units are attached at spaced intervals to the chain and are adapted to engage the tire of a vehicle to convey the vehicle through the washing unit. A provision is made at the entrance end of the conveyor for enabling the roller units to selectively by-pass the vehicle tire. ...

A computer program communicates with a partition manager in the logical partition where the computer program is run. When resource allocation in the logical partition dynamically changes, the partition manager notifies the computer program of the configuration change. The computer program may autonomically adjust one or more configuration settings that affect performance of the computer program to dynamically tune the computer program to optimal performance each time the allocation of resources ...

The conveyor system features plural endless and independently powered conveyor chains traveling individual guide tracks, one chain and track representing a main power conveyor line traversing the entire length of the system, and one or more further and similar chain and track-type branch lines which, at spaced zones therealong, converge and diverge in relation to the main line, paralleling the latter through some length. Thus, pusher dogs on the parallel-traveling conveyor reaches may selectivel...
