    摘要: An ultrasonic transducer. The ultrasonic transducer has an interposer having electrical connectivity contacts. The ultrasonic transducer also has an ultrasonic receiver, comprising an array of receiving elements, physically fixed relative to the interposer and coupled to electrically communicate with electrical connectivity contacts of the interposer. The ultrasonic transducer also has at least one ultrasonic transmitter, separate from the ultrasonic receiver, physically fixed relative to the interposer and coupled to electrically communicate with electrical connectivity contacts of the interposer.

    摘要: A light emitting diode (LED) driver includes a first and second switches and control logic. The first switch is configured to switch on and off to regulate a voltage level at an output voltage node. The voltage level at the output voltage node is to power multiple LEDs. The second switch is configured to switch on and off to vary brightness of the LEDs. Based on an external signal, the control logic is configured to control first and second control signals to switch on and off the first and second switches, respectively. Based on an active time portion of the external signal, the control logic concurrently determines an active time portion of the second control signal and a number of switching cycles of the first control signal to switch on and off the first switch.

    摘要: Excessive latencies and power consumption are avoided when a large number of leaf nodes (LNs) contend simultaneously to join a time slotted channel hopping wireless communication network having a root node (RN) interfaced to LNs by one or more intermediate nodes (INs). A first plurality of shared transmit/receive slots (STRSs) is allocated for at least one IN, and a second plurality of STRSs is advertised for use by contending LNs, where the first plurality is larger than the second plurality. When a LN joins, its STRSs are re-defined such that most become shared transmit-only slots (STOSs) and no STRSs remain. The numbers of STRSs allocated to INs may vary inversely with their hop counts from the RN. One or more STOSs may be added for each of one or more INs in response to a predetermined network condition.
