  • Publication number: 20220163645
    Abstract: Methods for detecting a time-of-flight include: emitting a light pulse toward a target; detecting a presence of light received at a light detector; obtaining a delay time between emitting the light pulse and detecting the presence of the light at the light detector; responsive to obtaining the delay time, (a) updating an overall intensity counter that counts a total number of delay times that have been obtained and (b) updating a delay time counter out of a plurality of different delay time counters, wherein each delay time counter counts a total number of delay times obtained that have a corresponding delay time value; and monitoring a threshold of each delay time counter to determine whether a threshold value is exceeded.

  • Publication number: 20220069542
    Abstract: Illuminator modules having improved safety features are described. In some implementations, light to be emitted from a module is produced by a light source, and light reflected by an optical component disposed over the light source is detected by a photodetectors. A distribution of the reflected light detected by the photodetectors is monitored, and an optical output power of the light source is regulated if it is determined, based on the monitored distribution of light, that an unsafe level of light may be emitted from the module.

  • Patent number: 10338618
    Abstract: An LDO circuit comprises a pass element, and input stage, a current sink, a comparator and a control circuit. The pass element is configured to generate an output voltage depending on a gate signal and on an input voltage. The input stage is configured to generate a steering signal based on a deviation between a first reference signal and a feedback signal, the feedback signal being based on the output voltage. The current sink is controlled by a steering signal and connected between the gate control terminal and a reference terminal. The comparator is configured to compare the steering signal to a second reference signal and to generate a switch signal based on the comparison. The control circuit comprises a first current path and is configured to suspend, in particular temporarily suspend, the first current path depending on the switch signal.

  • Patent number: 9698679
    Abstract: A circuit for DC-DC conversion with current limitation comprises a DC-DC converter (100) with a coil (110) and a controllable switch (120) that can be switched into a low-impedance and a high-impedance state, and a current limiter (300a, 300b) for generating a control signal (IOC) for controlling the state of the controllable switch in the DC-DC converter (100). The current limiter (300a, 300b) is constructed such that the current (IL) through the coil at which the current limitation takes place is nearly independent of the ratio of the on-times and off-times of the controllable switch in the DC-DC converter (100).
