Abstract:
A delay apparatus of an embodiment is an apparatus for delaying a signal to a plurality of chain-based time-to-digital circuits (TDCs) and includes a plurality of propagation path devices each connected to a respective one of the plurality of TDCs. Each propagation path device is configured to delay a common start signal sent to each propagation path device by a selectable amount based on a delay selection signal received by the propagation path device, and to transmit the delayed start signal to the respective one of the TDCs.

Abstract:
Embodiments of the present disclosure provide techniques and configurations for an apparatus to reduce sensor power consumption, in particular, through predictive data measurements by one or more sensors. In one instance, the apparatus may include one or more sensors and a sensor management module coupled with the sensors and configured to cause the sensors to initiate measurements of data indicative of a process in a first data measurement mode, determine a pattern of events comprising the process based on a portion of the measurements collected by the sensors in the first data measurement mode over a time period, and initiate measurements of the data by the one or more sensors in a second data measurement mode. The second data measurement mode may be based on the pattern of events comprising the process. The pattern may indicate a prediction of appearance of events in the process. Other embodiments may be described and/or claimed.
