摘要： Methods and systems for allowing multiple devices to share the same serial lines (e.g., SDIO, SEN and SCLK) are provided. Such devices can be located, e.g., on an optical pick-up unit. Each device includes a serial interface, a device enable number (DEN) that differs from the DEN of each other device, and a plurality of registers, with at least one register being designated a device select register (DSR). The DSRs of the plurality of devices share a common address. The plurality of serial interfaces are collectively enabled and collectively disabled (e.g., via the SEN line). However, only one of the plurality of serial interfaces can be selected at one time, with the remaining of the plurality of serial interfaces being deselected. The serial interface of a device is selected when the DEN of the device is the same as the content of the DSR of the device, and deselected when the DEN of the device is not the same as the content of the DSR of the device.

摘要： An electronic device may be provided with a proximity sensor. The proximity sensor may include a light source such as a light-emitting diode and a light detector such as a photodiode. The light-emitting diode may be driven with an alternating current drive signal so that alternating current light is produced. The alternating current light may reflect off of an external object and may be received by the photodiode. The photodiode may receive a direct current light signal associated with the presence of ambient light. The efficiency of the photodiode may be affected by the level of ambient light and the efficiency of the light-emitting diode may be affected by the temperature of the light-emitting diode. Ambient light correction circuitry and temperature correction circuitry may be used to ensure that proximity sensor readings are not adversely affected by changes in operating temperature and ambient lighting conditions.

摘要： The present invention provides apparatus, kits and methods for assaying analytes using photoelectrochemical molecules as labels. Specifically, the present invention provides a method for assaying an analyte, comprising: a) contacting a sample suspected of containing an analyte with a reactant capable of binding and/or reacting with the analyte under suitable conditions to allow binding of analyte, if present in the sample, to the reactant; and b) assessing binding and/or reacting between the analyte and the reactant to determine presence and/or amount of analyte in the sample, wherein the reactant, analyte, or additional reactant or additional analyte or analyte analog is labeled with a photoelectrochemically active molecule. The assessing step also comprises converting the photoelectrochemically active molecule with light to an excited state in the presence of an electrode, and assessing an electric current generated by an electron transfer between the excited photoelectrochemically active molecule and the electrode.

摘要： Embodiments of the present invention generally relate to circuits, systems and methods that can be used to detect light beam misalignment, so that compensation for such misalignment can be performed. In accordance with an embodiment, a circuit includes a photo-detector (PD) having a plurality of electrically isolated PD segments. Additionally, the circuit has circuitry, including switches, configured to control how currents indicative of light detected by the plurality of electrically isolated PD segments are arithmetically combined. When the switches are in a first configuration, a signal produced by the circuitry is indicative of vertical light beam alignment. When the switches are in a second configuration, the signal produced by the circuitry is indicative of horizontal light beam alignment. The signals indicative of vertical light beam alignment and horizontal light beam alignment can be used detect light beam misalignment, so that compensation for such misalignment can be performed.

摘要： A phase adjuster (10) includes a delay-locked loop (14) and an interpolator (34). The delay-locked loop (14) includes a sufficient number of delay stages (24) to maintain a Π/2 radians phase shift across the one delay stage (24′) of a voltage-controlled delay line (20). The output signals (28 and 30) to this one stage (24′) are filtered, output from the delay-locked loop (14), and input to the interpolator (34). Within the interpolator (34), these output signals (28 and 30) are weighted and combined. The ratio of the weighting applied to the output signals determines the resulting adjusted phase of an output clock signal (36). The weighting can be a time-varying signal or otherwise programmed as needed to achieve a desired phase shift that is independent of clock speed and process variation.
