Abstract: Systems and methods are disclosed herein to provide improved jitter tolerant delay-locked loop circuitry. For example, in accordance with an embodiment of the present invention, an integrated circuit includes a plurality of delay cells each having a plurality of programmable delay taps. Each delay cell is adapted to provide a delayed clock signal delayed by a selected number of the delay taps. A phase detector is adapted to compare a first clock signal with a selected one of the delayed clock signals to obtain a comparison result and provide a plurality of control signals in response to the comparison result. An arithmetic logic unit (ALU) is adapted to vary the selected number of delay taps in response to the control signals provided by the phase detector.

Abstract: In one embodiment of the invention, a phase-locked loop (PLL) can be programmably controlled to add jitter to its PLL output clock. Such a PLL can be used to programmably inject jitter into the outgoing serial data signal generated by a serializer/de-serializer (serdes) that can be operated in an internal loopback mode, in which the outgoing serial data signal is internally looped back from the transmitter side of the serdes to the serdes receiver side. Jitter logic associated with the PLL can be operated in a register-based mode that does not rely on any externally generated jitter clock. Such register-based processing enables effective (1) internal loopback testing of unpackaged devices at the wafer stage as well as package devices at the package stage and (2) external loopback testing at the system level.

Abstract: In one embodiment of the invention, a clock-and-data-recovery (CDR) system has a multi-phase clock generator that generates a plurality of phase-offset clock signals and one or more channel circuits, each receiving a (different) input data signal and all of the phase-offset clock signals and generates an output data stream and a recovered clock signal. Each channel circuit has a plurality of data registers (e.g., flip-flops), each receiving the input data signal at its clock input port and a different one of the phase-offset clock signals at its data input port, such that the flip-flop is triggered at each (rising) edge in the input data signal. The channel circuit processes the outputs from the different flip-flops to select an appropriate phase-offset clock signal for use in sampling the input data signal to generate the output data stream, where the recovered clock signal is generated from the selected phase-offset clock signal.

Abstract: A grip element having a soft, compressible and deformable outer layer supported by an underlying support structure sufficiently rigid to maintain a receiving channel of the grip element in an open configuration. The support structure facilitates manipulation of the grip element and assembly of the grip element onto a hand-held article without having the outer layer collapse on itself as would occur without the support structure as a result of the soft, deformable nature of the outer layer. The grip element may be formed separately from the hand-held article on which it is to be assembled, and then positioned thereon such that the hand-held article is sold with the grip element pre-assembled thereon. If desired, the grip element may be provided separate from the hand-held article, the outer layer providing a readily compressible and deformable soft cushioning surface and the support structure facilitating insertion of the outer layer over at least a portion of a hand-held article.

Abstract: A bandgap reference circuit uses a pair of parallel loads and an op-amp driver circuit. The op-amp driver circuit uses NMOS inputs to sense voltage conditions at the loads. The configuration permits low-voltage response at low temperatures as a result of the configuration setting operating voltages above a saturation voltage. The op-amp driver provides an NMOS output, and a low-gain stage converts the NMOS output to an output corresponding to that of a conventional PMOS design.

Abstract: A set of interconnected delay stages, such as a voltage-controlled oscillator, has switch-controlled load circuitry connected to each output of each delay stage in the oscillator ring. In one embodiment, for each delay stage output, the switch-controlled load circuitry includes a switch, a transistor, and a current source. The switch is connected between the corresponding delay stage output and the transistor gate, the current source is connected between a power supply and the transistor drain, and the transistor source is connected to ground. In such a configuration, the transistor's gate-to-source capacitance can be applied to the corresponding delay stage output by closing the switch, for example, for lower-frequency operations. In addition, the output impedance of the current source decouples the capacitive load from the power supply, thereby substantially shielding the oscillator ring from noise in the power supply.

Abstract: Clock generation techniques are disclosed to provide clock generation with duty cycle replication. The clock generation techniques may further compensate for clock insertion delays and minimize distortion due to clock distribution networks.

Abstract: Mask (10, 10?, 21, 22) for use in coating a carbon-carbon composite brake disc (25) with anti-oxidant. The mask is composed of carbon-carbon composite material or nonreactive ceramic material. The mask is configured with edge ridges (11, 13) that are aligned with the outer and inner annular diameters of the carbon-carbon composite brake disc, a gasflow channel (12) between the ridges, and a gas access port (18) that allows gas to enter the gasflow channel. The mask may also include a gas exit port (16) having a valve (17) operatively connected thereto, so that gas flow may be restricted when pressure within the mask and carbon-carbon composite brake disc falls below a specified minimum value.

Abstract: An apparatus and method for programmable lock detection and correction (PLDC) to a programmable accuracy in a digital delay-locked loop (DLL) based multiphase clock generator (MCG) is based on a DLL that utilizes a digital count to control the delay of a digitally controlled, multiple-tap delay line in its feedback path where stability of the digital count is used to qualify the determination of lock to a programmable accuracy and lock determination is based on combinatorial evaluation of the multiple phase outputs for the proper waveform relationships. The incidence of false lock corresponding to excessive delay through the delay line is addressed by a LOOPRESET signal that results in a reset of the digital count that controls the delay through the delay line. Additionally, programmability of the stability interval, the digital counter step size, and the accuracy of the lock provide control over lock acquisition time.

Abstract: The invention relates to a clip (300) for capturing at least one capture member (401) within a capture zone (311). A gate (320) blocks an opening (310a) of the capture zone to thereby capture the capture member(s). The clip may be attached to a person by way of an attachment member (350), such as an attachment hook. A personal device such as a mobile phone (10) may be secured to the clip via a capture member locatable within the capture zone. Accordingly, the personal device is attachable to the person via the clip when worn by the person. The invention also relates to a clasp (500) that is capable of capturing a detention member (403) within a detention zone (530).

Abstract: A pivoting light socket is used in the light pan of an up-light fixture of a low clearance ceiling fan, the light pan is positioned above the fan blades to provide indirect lighting which reflects from the ceiling above the fan blades. The circular, trough-shaped light pan surrounds, and is coupled to, the top circumference of the ceiling fan's motor stator, with the trough shaped portion positioned below the top of the stator. The light bulbs have a pivoting light socket that allows the bulb and socket to be positioned substantially below the top surface of the stator when the light socket is in its horizontal position, parallel to the top of the stator. Tilting the light socket upward, toward a vertical position, allows the light bulbs to be easily replaced, especially if the trough-shaped light pan is deep or narrow.
