  • Publication number: 20210359605
    Abstract: An apparatus includes a first timer configured to determine a turn-off time of a first high-side switch of a buck-boost converter, and a second timer configured to determine a turn-off time of a second low-side switch of the buck-boost converter based on a comparison between a first signal and a second signal, the first signal being proportional to an input voltage of the buck-boost converter, and the second signal being generated based on a signal proportional to an output voltage of the buck-boost converter.

  • Publication number: 20210356568
    Abstract: Systems and methods for a Time of Flight (ToF) camera system configured to be operable in a proximity mode. In the proximity mode, the proximity of an object may be estimated by relatively delaying or offsetting the charge accumulation timing of multiple different columns of pixels of the ToF imaging sensor. The relative charge accumulated in those pixel columns is dependent on the proximity of the object and the relative time delays in charge accumulation of each column. Therefore, by reading out the charge accumulated in multiple different pixel columns and knowing the relative accumulation delay of those pixel columns, the proximity of an object may be determined. This enables the operation of the ToF camera system to be switched between relatively high power, full ToF depth imaging, and relatively low power proximity mode of operation, thereby rendering a single system as being capable of performing two different functions.

  • Publication number: 20210355641
    Abstract: Coconut crumb can serve as an infill material on synthetic turf fields in the place of tire crumb. The crumbs are less than 10 mm big and have smooth corners and edges. The process of producing the coconut crumb involves successive grinding or milling processes that reduce the inner hard shell of the coconut to particles of an appropriate size for infill, while screening out the unwanted material from being included in the infill.

  • Publication number: 20210356588
    Abstract: Various technologies described herein pertain to a time of flight lidar sensor system that uses a coherent detection scheme. The lidar sensor system includes a laser source, a semiconductor optical amplifier, a combiner, and a balanced detector. The laser source emits an input optical signal. The semiconductor optical amplifier receives a first portion of the input optical signal and outputs a modulated optical signal (amplified and modulated). The combiner receives a second portion of the input optical signal and a returned optical signal received responsive to transmission of at least a portion of the modulated optical signal. The combiner coherently mixes the second portion of the input optical signal with the returned optical signal and outputs mixed optical signals. The balanced detector detects the mixed optical signals and generates an output signal (e.g., a differential photocurrent), which can be used to detect a distance to a target.

  • Publication number: 20210354034
    Abstract: A method of and system for handling latency issues encountered in producing real-time entertainment such as games of skill synchronized with live or taped televised events is described herein. There are multiple situations that are dealt with regarding latencies in receiving a television signal with respect to real-time entertainment based on the unfolding games played along with the telecasts. Systemic delays, arbitrarily imposed delays of a broadcast signal and variances in the precise broadcast times of taped television programs have to be equalized so as to provide fair entertainment.

Front housings of the connector portions can each be rotated about the longitudinal axis of the ferrule without rotating the ferrule or the boot, to change the polarity of the two connector portions. The spacing between the two ferrules is adjustable. A holder holds the connector portions, the holder including side slots, the connector portions mounted to the holder by moving laterally to the side slots. The holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot.
