Abstract: A glide rack assembly removably installable within a cooking chamber. The assembly includes a support rack, an engagement member extending downward therefrom and being translatable between a fully retracted position and an extended position, and a locking arm. The locking arm is configured such that when the support rack is in the fully retracted position, the engagement member deflects said locking arm into an unlocked position wherein the locking arm does not cooperate with an embossment on a side wall of the cooking chamber. Further, when the support rack is translated from the fully retracted position, the engagement member does not deflect the locking arm such that the locking arm pivots to a locked position wherein the locking arm cooperates with the embossment such that the assembly is inhibited from being removed.

Abstract: An oven including a chamber defining an oven cavity with an open front. A rack assembly is slidable between a retracted position and an extended position relative to the chamber. A door is provided for closing the open front. A hinge assembly connects the door to the rack assembly. The hinge assembly allows the door to slide between a first position and a second position with respect to the rack assembly. The hinge assembly includes a lock assembly for locking the rack assembly in the extended position. The lock assembly is moveable between a locked position and an unlocked position. The lock assembly is in the unlocked position when the door is in the first position thereby allowing the rack assembly to freely moved, and the lock assembly is in the locked position when the door is in the second position thereby securing the rack assembly in the extended position.

Abstract: Aspects of a method and system for compensating temperature readings from a temperature sensing crystal integrated circuit are provided. An electronic device may digitize a temperature indication received from a temperature sensing circuit, digitize one or more calibration voltages received from said temperature sensing circuit, and calculate a compensated temperature indication utilizing the digitized calibration voltage(s), and the digitized temperature indication, and data from a table that characterizes behavior of the temperature sensing circuit as a function of temperature. One or more circuits in the electronic device may be controlled based on the compensated temperature indication. The compensated temperature indication may compensate for a gain error and/or offset error of a digital to analog converter that digitizes the temperature indication and the calibration voltage(s). There may be two calibration voltages.

Abstract: Aspects of a method and system for compensating temperature readings from a temperature sensing crystal integrated circuit are provided. In this regard, a temperature indication and calibration voltages from a temperature sensing crystal integrated circuit (TSCIC) may be digitized and the digital signals may be utilized to calculate a compensated temperature indication. Data derived from a memory integrated within the TSCIC may be retrieved based on the compensated temperature indication. The retrieved data may be utilized to control operation of one or more circuits. The compensated temperature indication may be calculated by removing a gain error and/or offset error from the digitized temperature indication. The compensated temperature indication may be utilized as an index for a data table. The compensated temperature indication may be a normalized compensated temperature indication. The calibration voltages may include a minimum voltage and/or a maximum voltage that the TSCIC is operable to output.

Abstract: A source-follower transistor based buffer provides high linearity. A replica transistor is used to generate a replica voltage substantially equal to the output voltage of the buffer. The replica voltage is level shifted by a level shift circuit and applied at the drain of the source-follower transistor to improve the linearity of the buffer. The buffer may be used in conjunction with a switched-capacitor sampling circuit. A damping circuit may be used to reduce charge glitches due to sampling. The damping circuit may be a low pass filter. The buffer may be used in an interface circuit that produces an output signal from an input signal and controls the level of the output signal.

Each half-circuit includes a feedback loop coupled to the resistor. The feedback loop includes an input transistor coupled to an inverting gain stage. The inverting gain stage is coupled to an output transistor which in turn is coupled to the input transistor and the resistor. In a low noise transconductance cell, a bias current source is coupled to the center of series connected resistors. In a high swing transconductance cell, a first bias current source is coupled to the left terminal of a resistance stage and a second bias current source is coupled to the right terminal of the resistance stage. The resistance stage can include a single resistor or a plurality of resistors.

Abstract: A toroidal continuously variable transmission with offset rollers includes a first and second toroidal disk each having inwardly facing toroidal portions that face opposite each other. A shaft having a longitudinal axis mounts the first toroidal disk on a first end and mounts the second toroidal disk on a second end. A sliding collar is mounted on the shaft between the first and the second toroidal disks and has at least two off-set rollers attached thereto. The off-set rollers are in communication with the first and the second inwardly facing toroidal portions of the toroidal disks. Translation of the sliding collar on the shaft causes the off-set rollers to rotate about a first axis, wherein the first axis is orthogonally disposed with respect to the longitudinal axis of the shaft.

Abstract: In a high-fidelity digital modulator, a mapper is provided to minimize quantization noise, jitter, and cross-talk between multiple digital-to-analog or analog-to-digital converters. The mapper receives a quantized level from a quantizer and maps the quantized level to an output sequence. The mapper includes a table defining multiple sequences corresponding to each quantized level. Each sequence includes two or more symbols, having one of multiple values. The mapper also includes a generator that selects one of the multiple sequences as the output sequence. The last symbol of a first output sequence is equal to the first symbol of the next output sequence and so on. The generator selects the output sequence by alternating between a first and a second sequence for each quantized level received. The generator selects the output sequence by alternating between sequences having a positive and a negative common mode energy for each odd valued quantized level received.

Abstract: A continuously variable transmission comprising; a drive disk; a driven disk, a plurality of rollers, and tubular support member. Each roller is rotatably attached to a shaft which is pivotally attached to a stanchion, which is fixed to one face of the tubular support member. One face of each disk contains an annular cavity. Said faces are positioned to form a toroid around the longitudinal axis. The rollers are rotatably placed within the toroidal chamber in contact with both the driven and driving disks. The annular fixing of center of rotation of the rollers permits the driving disk to impart rotation to the rollers and thereby to the driven disk. Tubular support member longitudinal movement changes the plane of rotation of the rollers relative to the longitudinal axis causing a difference in the rate of rotation of the driven disk relative the rate of rotation of the driving disk.

Abstract: Methods and systems for applying digital dither in data converters, such as delta-sigma data converters. In one embodiment, an analog signal from a first path of a delta-sigma modulator is quantized to an m-bit digital signal and an n-bit dithered digital feedback signal is generated from at least a portion of the m-bit digital signal. The n-bit dithered digital feedback signal is converted to an analog feedback signal and fed back to a second path of the delta-sigma modulator. In another embodiment, the n-bit dithered digital feedback signal is generated by selecting one of a plurality of sets of n-bits from the m-bit digital signal depending upon a state of a dither control signal. The dither control signal can alternate or pseudo-randomly switch between a plurality of states. The m-bit digital signal may be an m-bit thermometer code signal.
