  • Patent number: 12148647
    Abstract: An apparatus includes a substrate holder, a first actuator to rotate the substrate holder, a second actuator to move the substrate holder linearly, a first sensor to generate one or more first measurements or images of the substrate, a second sensor to generate one or more second measurements of target positions on the substrate, and a processing device. The processing device estimates a position of the substrate on the substrate holder and causes the first actuator to rotate the substrate holder about a first axis. The rotation causes an offset between a field of view of the second sensor and a target position on the substrate due to the substrate not being centered on the substrate holder. The processing device causes the second actuator to move the substrate holder linearly along a second axis to correct the offset. The processing device determines a profile across a surface of the substrate based on the one or more second measurements of the target positions.

  • Patent number: 12081056
    Abstract: A controller for managing a battery pack includes: a detection terminal, for transmitting an enable signal when values of battery parameters for the battery pack satisfy a sleep condition, where the enable signal enables the detection circuit to detect whether the battery pack is connected to a load and whether the battery pack is connected to the charger; and a receiving terminal, for receiving a detection result transmitted by the detection circuit. The detection result indicates whether the battery pack is connected to at least one of the load and charger. The controller controls the battery pack to enter a sleep mode of the sleep modes based on the detection result. The controller also includes a control terminal, for transmitting a control signal to control an on/off state of a charging switch and/or a discharging switch. The control signal is generated by the controller based on the detection result.

  • Publication number: 20240283417
    Abstract: The present application discloses a radio frequency (RF) device. The radio frequency device includes a power amplifier, a power detector, and a digital signal processor (DSP). The power amplifier outputs a RF signal. The power detector receives the RF signal, and performs a plurality of calibration operations to generate a plurality of calibration voltages corresponding to a plurality of bias voltage, wherein the calibration operations are performed at the bias voltages respectively, and the calibration voltages are temperature-correlated due to that electrical characteristics of the power detector are temperature-correlated. The DSP controls the power detector to operate at the bias voltages, obtains an index voltage for indicating power of the RF signal by performing calculations upon the calibration voltages to reduce temperature dependency of the index voltage, and adjusts a gain of the power amplifier according to the index voltage.

  • Patent number: 12055591
    Abstract: In a battery management controller, analog-to-digital conversion circuitry converts analog signals, indicative of a battery voltage, a battery current, and a battery temperature, to digital signals. A memory stores a remaining-capacity lookup table that includes multiple groups of data. Each group of data includes a voltage, a current, a temperature, and a parameter associated with a remaining capacity corresponding to the voltage, the current and the temperature. A processor searches the lookup table for a current parameter value and an end-of-discharge parameter value based on the digital signals, and determines a full available charge capacity of the battery based on the current parameter value and the end-of-discharge parameter value. The processor also counts the number of charges flowing through the battery based on a battery current. The processor further determines an available state of charge of the battery according to the full available charge capacity and the number of charges.
