摘要： In one embodiment, harmful solar cell polarization is prevented or minimized by providing a conductive path that bleeds charge from a front side of a solar cell to the bulk of a wafer. The conductive path may include patterned holes in a dielectric passivation layer, a conductive anti-reflective coating, or layers of conductive material formed on the top or bottom surface of an anti-reflective coating, for example. Harmful solar cell polarization may also be prevented by biasing a region of a solar cell module on the front side of the solar cell.

摘要： The present subject matter provides technical solutions for the technical problems facing cryogenic ion traps by providing a cryogenic radio-frequency (RF) resonator that is compact, monolithic, modular, and impedance-matched to a cryogenic ion trap. The cryogenic RF resonator described herein is power-efficient, properly impedance-matched to the RF source, has a stable gain profile, and is compatible with a low temperature and ultra-high vacuum environment. In some examples, the gain profile is selected so that the cryogenic RF resonator acts as a cryogenic RF amplifier. This cryogenic RF resonator improves the performance of ion traps by reducing or minimizing the heat load and reducing or minimizing the unwanted noise that may erroneously drive trapped ions. These features of the present subject matter improve the performance of atomic clocks and mass spectrometers, and especially improve the performance of trapped ion quantum computers.

摘要： The present invention relates to an AC/DC converter (1) of the type having an AC/DC conversion stage (2) and a DC/DC conversion stage (3), the AC/DC conversion stage (2) comprising an input filter stage (4), an input rectifier stage (5) and a tracking boost converter stage. The boost converter stage in turn comprises an input choke (10), a boost diode (16) and a bulk capacitor (17). The bulk capacitor (17) is arranged to store a range of voltages substantially proportional to the input voltage of the converter. The DC/DC stage (3) is arranged to receive the range of voltages from the bulk capacitor (17) and is controllable to provide a desired DC output regardless of the voltage received from the bulk capacitor (17). This is achieved through careful combination of components and use of output feedback control to control the voltage applied to an isolated transformer (41) in the DC/DC stage.

摘要： An electrical LC resonant circuit, particularly useful for channel filters in carrier frequency technology, has a fixed-tuned coil and a capacitor tunable by the removal of layer surface portions. The capacitor is constructed as an essentially flat, self-healing layer capacitor having a relatively small number of layer surfaces and dielectric layers lying one upon the other.

摘要： A temperature-compensating system for piezoelectric crystal oscillators and other electromechanical resonators whose operating frequency varies as a function of ambient temperature. The system includes a temperature transducer for producing an analog measuring signal as a function of temperature within the temperature range of interest, which analog signal is converted into a corresponding binary number. The number is applied as an input to a logical function generator programmed to produce for each input number, an output binary number whose value depends on the generated function. The output number is converted to an analog control signal which is applied to a responsive element coupled to the resonator to vary the operating frequency thereof. The arrangement is such that the curve of the frequency shift due to the analog control signal, inversely matches the frequencytemperature curve of the resonator to effect exact frequency compensation therefor.

摘要： A voltage clamping circuit includes a current source having a fixed current source and a variable current source and a variable resistor receiving current from the current source. The variable resistor varies its resistance in response to an environmental operating condition. The voltage clamping circuit also includes an amplifier configured to compare a sensor node voltage with a reference voltage, the sensor node voltage being in communication with the voltage drop across the variable resistor. The amplifier is configured and connected to provide a control output to control the variable current source to modify current output from the variable current source to at least in part prevent the sensor node voltage from exceeding a reference voltage when certain operating conditions are present.

摘要： A re-balancing device (1) comprising a line (12). Said line comprises a first pole (3) of a first conductor (2) and a first pole (6) a second conductor (5) on a first side (8), in addition to a second pole (7) of a first conductor (2) and a second pole (7) of a second conductor (5) on a second side. The second side (9) of the line (12) is connected to a network consisting of impedances and a symmetrical connection (Out), with a first end (10) and a second end (11). The first pole (3) of the first conductor (2) is directly guided to a reference potential (GR) and the two first poles (3,6) form an unsymmetrical connection (In). The second pole (4) of the first conductor (2) is connected to the first end (10) of the symmetrical connection (Out) and connected to the reference potential (GR) via the third impedance (x3). The second pole (7) of the second conductor (5) is connected, by means of the first impedance (x1) to the second end (11) of the symmetrical connection (Out) and to a pole of the second impedance (x2). The second impedance (x2) is connected to the reference potential (GR). All impedances (x1,x2,x3) are electromagnetically decoupled from each other.
