Abstract: A process of recycling fibrous materials, specifically carpet and diaper remnants, or high melting polymers, specifically PET, by using low melting polymers, i.e. agricultural film and other products made from polypropylene and polyethylene, to create parts of high compressive strength. The carpet, fibrous materials, or PET and low melting polymers are ground separately and then blended in a predetermined ratio. The blend is then sent through a pellet mill and then heated until the low melt polymer is melted, or approximately 450° F. The melted mixture is then injected into a partially opened cavity mold, which is then closed without allowing the excess material to escape. Closing the mold increases the internal pressure on the molten material. The cavity mold is then rapidly cooled.

Abstract: A method and apparatus for fail-safe and restartable system clock generation provides recovery from failures due to incorrect clock generator settings or from marginal clock distribution components. Clock failure is detected at a point along the clock distribution path between the output of the clock generator and the downstream circuits. If a clock failure is detected, a second clock, which may be the clock generator reference clock, is used to operate the downstream circuits. The clock generator, which may be a phase-lock loop, is then restarted, either with a predetermined loop filter voltage at which downstream circuits are guaranteed to operate, or with a divider setting on the output of the clock generator that reduces the frequency so that downstream circuits are guaranteed to operate. Parameters of the clock generator can thereby be reset and operating conditions determined before restoring the output of the clock generator to the downstream circuits.

Abstract: A method and apparatus for the support of an article provided as a single article of manufacture adapted to rest in the trunk or cargo area of a vehicle or any other flat surface. The single article of manufacture is able to be separated into at least two pieces that interlock to form the support that cradles the article at an angle such that the base of the article maintains contact with the floor of the vehicle while the top of the article is held in an upright position.

Abstract: An integrated circuit includes a testable delay path. A transition of a delay path input signal causes a subsequent transition of a delay path output signal. A pulse generator receives the delay path input and output signals and produces a pulse signal having a pulse width indicative of the delay between the delay path input and output signal transitions. A delay line receives the pulse signal from the pulse generator. The delay line generates information indicative of the pulse signal pulse width. The delay line may include multiple stages in series where each stage reduces the pulse width of the pulse signal. The delay line may include a high skew inverter having PMOS and NMOS transistors having significantly different gains. The pulse generator is configured to produce a positive going pulse signal regardless of whether the delay path is inverting or non-inverting.

Abstract: A pseudo Set/Reset latch circuit is configured with modified NOR or NAND gates wherein one of the series pull-up devices or pull-down devices is removed. A minimum of three pseudo Set/Reset latches may be coupled as a ring oscillator generating an output and a non-skewed complementary output. Additionally, feed-forward inverting stages may be coupled in parallel with inverting paths in the ring oscillator primary path to further increase the frequency range of the ring oscillator. The pseudo Set/Reset latch circuits and the feed-forward inverting stages may be configured with voltage controlled devices that alter the delay of the stages as a means for varying the frequency of the ring oscillator either by varying the current drive of the circuitry driving the output of the latch stages or by varying the conductance of devices coupling between the latch stages. Feedforward inverting stages may comprise pseudo latches or inverter gates.

Abstract: A circuit and method of correcting the duty cycle of digital signals is disclosed. The duty cycle of an input digital signal is measured and compared to a desired duty cycle. The leading edge of the input digital signal is passed to an output. The circuit and method adjust the falling edges at the output to achieve the desired duty cycle. The falling edges occur in response to rising edges of a delayed version of the input digital signal.

Abstract: A VCO is configured using a ring oscillator with voltage controlled feedforward inverting stages coupled around the inverting stages making up the basic ring oscillator to enable the frequency of the ring oscillator to be voltage controlled. A latch and multiplexer is used to select between two or more outputs within the ring oscillator to change the basic frequency range of the VCO glitch free. To achieve a wide range VCO, additional stages are added to the basic ring oscillator. When the number of stages is an odd number greater than seven, then the voltage controlled feedforward inverting stages feedback to the outputs of the first and second inverting stages of the ring oscillator. Two additional multiplexers are added to select which feedforward inverting stage is coupled to the first and second inverting stage. This allows a wide range interleaved VCO that switches between frequency ranges glitch free.
