A cap for a quick connect fitting assembly is a unitary component having a terminal portion and a body portion extending from the terminal portion to define an inner cavity. The body portion defines a first opening opposite the terminal portion and a second opening extending from the first opening toward the terminal portion. The terminal portion has a first locating feature and the body portion has a second locating feature. The first locating feature and the second locating feature are spaced relative to one another such that the unitary component will connect to the quick connect fitting assembly with both of the locating features contacting predetermined locations of the quick connect fitting assembly only if a male fitting is inserted into a female fitting to a predetermined position, the unitary component thus ensuring proper connection of the quick connect fitting assembly. A method of assembly using the cap is also provided.

An array of ferroelectric memory cells that allows imprint mitigation includes ferroelectric memory cells respectively coupled to word lines, plate lines, and bit lines; a word line driver for driving the word lines; a plate line driver for driving the plate lines; a bit line driver for driving the bit lines; and an isolation device driver for driving isolation devices coupled between the bit lines and a plurality of bit lines. The method for mitigating imprint includes coupling the bit lines to a respective plurality of sense amplifiers, turning on a word line and pulsing a plate line associated with a row of ferroelectric memory cells, disconnecting the bit lines from the respective sense amplifiers, driving the plate line low and the bit lines high, driving the plate line high and the bit lines low, driving the plate line low and floating the bit lines, driving the bit lines with the sense amplifier, and turning off the word line and precharging the bit lines. The method can be performed after each memory access, or can be performed whenever convenient with a counter and a rejuvenate command.

The present invention is directed to methods for extracting a kerogen-based product from subsurface (oil) shale formations, wherein such methods rely on fracturing and/or rubblizing portions of said formations so as to enhance their fluid permeability, and wherein such methods further rely on chemically modifying the shale-bound kerogen so as to render it mobile. The present invention is also directed at systems for implementing at least some of the foregoing methods. Additionally, the present invention is also directed to methods of fracturing and/or rubblizing subsurface shale formations and to methods of chemically modifying kerogen in situ so as to render it mobile.

A counting scheme for a non-volatile counter includes automatic point-of-reference generation implemented in a state machine. Two state variables are used to store the rotation history of the magnet. One variable stores the previous position of the magnet and the other stores the net angle traveled by the magnet from the reference point. The first pulse location after the counter is reset is automatically selected as the reference point until the next counter reset. When the nonvolatile counter counts up or down, i.e. when the magnet travels 360° in either direction, the second state variable is set to zero and the first state variable is set to the reference point, indicating the start of a new revolution.

An integrated circuit first-in, first-out ("FIFO") memory device comprises an input bus for receiving data, an input buffer coupled to the input bus for storing the data and at least one dynamic random access memory ("DRAM") array coupled to the input buffer. A write pointer is operative for storing the data in the input buffer to a location within the memory array indicated and an output bus is coupled to the memory array and a read pointer for providing previously written data from the memory array at a location indicated by the read pointer. In a preferred embodiment, the FIFO further comprises at least one static random access memory ("SRAM") cache interposed between the input and output buses and the memory array having a width corresponding to each row of the memory array. In an alternative embodiment, the FIFO memory device includes a "Retransmit" feature which allows data to be read from the device multiple times as well as the Read Pointer to be selectively placed under user control. In a specific embodiment, the Read or Output bus may also be used as an address bus.

A system and method for mitigating undesired imprint effects in a ferroelectric memory array through the addition of a complementary data path which allows user data to be written to the array in an inverted state and then subsequently read out from the array in a re-inverted state in response to the state of at least one indicator bit corresponding to each row of the array.
摘要:
A data communication system receives data signals transmitted via a signal path and applies to the received signal a high-pass function including a low-pass filter and a summing circuit. The signal is low-pass filtered, and the summing circuit subtracts the filtered signal from the received signal to generate a high-pass signal, which is summed with a quantized-feedback signal to generate a recovered data signal. The quantized-feedback signal is provided by applying to the recovered data signal a low-pass function having a transfer function which is substantially complementary to the transfer function of the high-pass function. The low-pass function low-pass filters the recovered data signal to generate the quantized-feedback signal.
