Abstract: In embodiments, an apparatus to predict failure of a laser is presented. The apparatus may include a memory to store a reference model of bias current change for a laser as a function of time and temperature, one or more sensors to detect: temperature, elapsed operating time and bias current of the laser, and a processor communicatively coupled to the memory and to the one or more sensors. The processor may be to calculate an actual bias current change ?IA at a current laser temperature, and an expected bias current change ?IE, based at least in part on the reference model and an average operating temperature, subtract ?IE from ?IA, and if the difference is greater than a pre-defined value ?, output a signal. Related methods and non-transitory computer-readable media may also be presented.

Abstract: Some examples include a plurality of secure low-power compressive sensing sensor blocks able to communicate with each other and with a computing device to perform spatial and/or temporal compressive sensing. As one example, a first sensor block may obtain data by randomly sampling a sensor signal from a first sensor coupled to the first sensor block. The first sensor block may send the data obtained from the randomly sampled sensor signal to at least one other sensor block of the plurality of sensor blocks, wherein the data is distributed to the plurality of sensor blocks. In addition, at least one of the first sensor block or another sensor block may process the data to at least one of packetize or encrypt the data. The first sensor block and/or the other sensor block may send the processed data to the computing device.

Abstract: Embodiments herein relate to optoelectronic transceivers with power management. An optoelectronic device may include a photodetector, a loss of signal (LOS) detector coupled with the photodetector, and a re-timer coupled with the LOS detector, wherein a component of the re-timer is to be disabled in response to a detection by the LOS detector that an optical signal has not been received for a predetermined time period. In some embodiments, the LOS detector is coupled with a driver disable input of the re-timer and a driver component of the re-timer is to be disabled. In some embodiments, a clock data recovery circuit, a transmit module re-timer and modulator, and/or a laser may be disabled. In various embodiments, components may be re-enabled in response to detection that an optical signal is being received and/or an electrical signal is received for optical transmission. Other embodiments may be described and/or claimed.

Abstract: Some examples include a secure low-power sensor platform able to be used for activity monitoring or other purposes. For instance, a sensor system may sense sparse signals using compressed sensing. As one example, compressed sensing may be used to obtain sparse signals from analog sensor signals received from one or more sensors. The data obtained by compressed sensing may be sent subsequently to a computing device to reconstruct the sensor signal. Examples herein enable lower power usage, lower cost, and lower weight than conventional devices, while also enabling processing advantages, such as less overall data to process and lower data storage utilization.
