Abstract: Described herein is a device for autonomously monitoring a battery is provided. The device is integrated with the battery (e.g., by being electrically coupled to the battery). The device obtains measurement data by injecting electrical signals into the battery and measuring an electrical response of the battery. The device participates in an authentication protocol with a computing device to verify a unique identity of the device to the computing device. After performing the authentication protocol verifying the unique identity of the device, the device transmits battery data to the computer. Further, techniques for verifying the identity of the battery using measurement data obtained by the device are described herein. The techniques generate a battery signature using the measurement data that is then used to verify the identity of the battery. For example, the battery signature may be used to determine whether the battery is counterfeit or defective.

Abstract: This disclosure describes techniques to count objects across multiple zones of arbitrary shapes. The techniques include operations comprising: detecting an object in a first zone of a plurality of zones of an area; determining that the object has moved from the first zone to a second zone of the plurality of zones; determining that movement of the object from the first zone to the second zone fails to satisfy a zone transition criterion for updating a count value and time criterion; and in response to determining that the movement of the object from the first zone to the second zone fails to satisfy the zone transition criterion, preventing the count value from being updated.

Abstract: A vehicle includes microphones (102,104,106) and a system for detecting a lifeform in the vehicle (100), such as a pet or child left behind in a vehicle. Detecting the lifeform includes obtaining sound signals captured by the microphones and performing a spectral response analysis of the sound signals. The spectral response analysis is based on frequency-based attenuation of the vehicle. The lifeform detection system determines, based on the spectral response analysis, whether a source of a sound captured by at least one of the plurality of microphones is located inside the vehicle, and if it is, generates a notification in response to determining that the source of the sound is located inside the vehicle.

Abstract: Apparatus and methods for transceivers are provided herein. In a first aspect, an observation receiver is implemented to detect common-mode local oscillator (LO) leakage while the observation receiver performs other functions. In a second aspect, a transceiver is implemented with an LO leakage compensation circuit that compensates a transmitter for LO leakage using a digital filter, such as a Kalman filter, that combines differential LO leakage observations with common-mode LO leakage observations. In a third aspect, a transmitter includes multiple local loopback paths including a first loopback path after a variable gain amplifier (VGA) and a second loopback path before the VGA.

Abstract: Physical Unclonable Functions, PUFs, are hardware devices designed to generate a number that is random (i.e., two identical PUFs should produce randomly different numbers from each other) and persistent (i.e., a PUF should consistently generate the same number over time). Over time, aspects of the PUF hardware may change or drift, which may ultimately cause the generated number to change, and therefore no longer be persistent. Failure to generate a persistent number may cause difficulties for other devices that rely on the persistence of the number generated by the PUF, for example as part of a cryptographic process. The present disclosure relates to monitoring over time the physical characteristics of the PUF that are used to generate its number, and thereby keep track of its reliability to generate a random number that is persistent. By monitoring PUFs in this way, it may be possible to detect in advance a PUF that is at risk of generating a number that is no longer persistent, so that pre-emptive action may be taken before the PUF actually fails.

Abstract: Sensors and methods for determining the state of charge of a battery are described. The state of charge is determined in some instances by applying a current perturbation having a frequency to the battery terminals, monitoring the response signal, and determining the phase of the response signal. The phase may be correlated to the state of charge of the battery, so that once the phase is determined, a determination of the state of charge of the battery may be made. In some situations, the state of charge may be used to determine the operating condition of a load connected to the battery. In some embodiments, the state of charge may be used to determine whether the battery is defective.

Abstract: Embodiments of the present disclosure may monitor and adjust a sampling rate of an ADC for converting the power signal to a digital signal, locking onto the phase and frequency of the power signal. This technique may make the sampling process coherent relative to the power signal. Properties of the power signal, such as phase, frequency, and magnitude, may be extracted relative to an idealized power signal.

Abstract: A serial interface, such as a serial peripheral interface (SPI), with improved diagnostic coverage is disclosed. The serial interface includes a data verification module that selects an error detection value in response to a mode signal indicating if the transmitting device is in user mode or test mode. For example, the data verification module computes a cyclic redundancy check (CRC) value and selects either the computed CRC value or its inverse based on the mode. The receiving device can determine the mode of the transmitting device based on the error detection value used. The serial interface further includes a read detector for clearing the transmit data buffer after data is read out. The serial interface may further include a loopback circuit for verifying that the data output from an output pin matches the data from the transmit data buffer.

Abstract: Micro-isolators exhibiting enhanced isolation breakdown voltage are described. The micro-isolators may include an electrically floating ring surrounding one of the isolator elements of the micro-isolator. The isolator elements may be capacitor plates or coils. The electrically floating ring surrounding one of the isolator elements may reduce the electric field at the outer edge of the isolator element, thereby enhancing the isolation breakdown voltage.
