Abstract: A system for tracking tread wear of a tire of a vehicle includes a processor configured to obtain a new tire rotational count value representing expected rotations of the tire over a set distance if the tire were new. A position tracking device is coupled to the vehicle and configured to track a distance traveled by the vehicle and report the distance to the processor. A wheel speed sensor is coupled to the vehicle and configured to track rotations of the tire. The processor determines a current tire rotational count value representing the number of rotations of the tire over the set distance. The processor then determines a tire tread wear value based on the new tire rotational count value and the current tire rotational count value. A display device is configured to display indicia based on the tire tread wear value.

Abstract: A single memory space of a device having a dedicated functionality is dynamically partitioned to provide separate memory partitions for access by different processes along a production stream. Firmware in the device that controls the overall functionality of the device also controls partitioning of the memory space. The firmware also controls how each of the partitions may be accessed. The firmware includes a number of different safety features for protecting data in the device and applies each of the safety features utilized by the device to each of the memory partitions. Data security is implemented independently for each partition in order to maintain functional safety compliance of the device. The different partitions can be created and accessed at different points in a production stream by different entities such as a device manufacturer, its customers and suppliers or other entities along the supply chain.

Abstract: A sensor includes a port body which defines an axial passage for receiving fluid. An electrical connector extends through an opening in the port body near a crimp portion opposite the axial passage and forms an upper seal with the port body. Within the interior of the port body, a support ring and base cover form a cavity which retains a sensing element. The sensing element is exposed to the fluid within the axial passage and determines the pressure. An annular seal is retained by the base cover. The crimp portion of the port body is crimped to provide an upper seal and apply a force on the components within the interior, pinching the annular seal between the sensing element and the base of the port body to create a lower seal.

Abstract: A combined pressure and temperature sensing device includes a sensor port geometry that provides improved contact between a fluid media being measured and a thermistor cavity of the sensor port. The increased contact area provides improved response time and accuracy compared to previously known integrated pressure-temperature sensors.

Abstract: An electromagnetic coil with improved insulation properties at high temperatures. A bobbin is insulated by a thin ceramic composite layer that is produced by winding a glass or ceramic fiber over the support structure and impregnating it with a pre-ceramic polymer.

A ceramic coated magnet wire is then wound around the insulated support structure. The magnet wire is a conductor that is spiral-wrapped with a glass fiber impregnated with a pre-ceramic polymer.
