    Abstract: A sensor package is disclosed. The sensor package can include a support structure that is configured to couple with a vibration source by way of a stud. The sensor package can include a cap that is at least partially disposed over the support structure. The cap at least partially defines a cavity. The sensor package can include a vibration sensor module that is coupled to a portion of the support structure and disposed in the cavity. The sensor package can have a mechanical resonant frequency in a range of 0.1 Hz to 11 kHz. The sensor package can include a connector that is coupled to the support structure. The connector can connect to a connection line to electrically connect the vibration sensor module to an external substrate or system. The support structure can include a material that has a Young's modulus of at least 60 GPa and a density less than 3000 kg/m3. The sensor package can include a filler material disposed in the cavity.

    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: 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: 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.
