  • Publication number: 20250137417
    Abstract: A pressure-based piston top-dead-center (“TDC”) position measurement system is disclosed, comprising: a fuel injector configured to inject fuel into a combustion chamber bounded in part by the piston; and a controller configured to control the fuel injector to cause a fuel injection when the piston is at each of a plurality of different positions relative to TDC while ensuring fuel is provided to the fuel injector at a substantially constant pressure. The controller is further configured to estimate a pressure in the combustion chamber in response to each fuel injection, fit a curve to the estimated pressures, and determine a TDC position of the piston as correlating with a maximum pressure on the curve.

  • Publication number: 20250105854
    Abstract: In described examples, a circuit includes a multiplexer. The multiplexer receives an input voltage and a calibration signal. An analog-to-digital converter (ADC) is coupled to the multiplexer and generates an output code in response to the calibration signal. A storage circuit is coupled to the ADC and stores the input code representative of the calibration signal at an address corresponding to the output code. The stored input code includes an index value and a coarse value.

  • Patent number: 12261838
    Abstract: The method provides an automated and scalable system for the generation, distribution, management of symmetric pre-shared keys (PSKs) to applications executing on headless and mobile devices. It helps achieve device protection, application security, and data protection with data authenticity and confidentiality in intra-device, inter-device, device-to-edge, and device-to-cloud communications. It helps Transport Layer Security (TLS) enabled applications dynamically acquire and renew PSKs and use identity hints for PSK based authentication ceremony during a TLS handshake. It helps client-server applications dynamically acquire and renew PSKs using keyed-hash message authentication code (HMAC) for data integrity and authenticity, content signing, and data encryption for confidentiality. It helps manage and distribute API shared secrets and API access tokens required for authenticated API requests and API security.

  • Patent number: 12146449
    Abstract: At least some embodiments of present disclosure direct to a fuel injection timing drift detection and/or compensation system. In some cases, the system collects or receives a series of fuel pressure data measured by one or more fuel pressure sensors. The system is configured to receive an indication of fuel flow cutout and a start-of-injection command signal. The system calculates a set of pressure drops using the series of fuel pressure data and identifies a selected pressure drop greater than a predetermined threshold to determine a measured start-of-injection timing based on the selected pressure drop. The system is further configured to evaluate whether a fuel injection drifting occurs based on received start-of-injection command signal and the measured start-of-injection timing. In some cases, the fuel injection drifting is used to either compensate fuel injection timing or raise a flag indicating the drifting.

  • Patent number: 12132842
    Abstract: An Internet of Things (IoT) device with zero touch provisioning includes one or more processing devices; a secure element; and memory storing software that, when executed in the one or more processing devices, cause the one or more processing devices to: install one or more clients on the IoT device for provisioning, enrollment, and updating, based on a device configuration; store an immutable device identity and a signing certificate in the secure element; and responsive to the IoT device being powered-on, cause the one or more clients and the secure element to perform the zero touch provisioning of the IoT device. The one or more clients on the IoT device for provisioning, enrollment, and updating operate with corresponding services with all communicating being encrypted, thereby protecting against cloning and counterfeiting of IoT devices.
