Publication number: 20190258812Abstract: 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.Type: ApplicationFiled: February 20, 2018Publication date: August 22, 2019Applicant: Sensata Technologies, Inc.Inventors: Eric A.

Patent number: 10129339Abstract: A communication system for transmitting sensor values to an Electronic Control Unit (“ECU”) includes a chain of ASICs (sensor interface devices). Each ASIC is coupled to sensors. All sensors connected to an ASIC are measured by said ASIC to obtain sensor values for transmission via a SENT stream in the direction of an ECU. An ASIC is further able to read and decode a Single Edge Nibble Transmission (“SENT”) stream from a previous ASIC in the chain. The ASIC combines its own measurements with the measurements received via the SENT stream to one SENT output stream carrying the sensor values of all sensors connected to said ASIC and all previous ASIC in the chain for transmission to a subsequent ASIC in the chain or the ECU. Only one SENT-input is needed at the ECU to receive measurements from multiple sensors, wherein the number of sensors can easily be changed.Type: GrantFiled: November 15, 2017Date of Patent: November 13, 2018Assignee: Sensata Technologies, Inc.Inventors: Mark Johannes Gerhardus Boerrigter, Danny Johannes Hendrikus Slotboom

Patent number: 10118326Abstract: A mold fabrication element has a hollowed volume defining a respective continuous inner surface. A fabricator resource disposes the mold fabrication element into a cavity of an injection mold assembly; surface contours on the inner surface of cavity as well as the respective continuous inner surface of the mold fabrication element exposed in the cavity define an outer surface of a resulting injection molded part. To create the injection molded part, the fabricator resource injects liquefied material into the cavity. The injected material contacts the continuous inner surface of the hollowed volume in the mold fabrication element as well as the surface contours of the cavity. After the injected material solidifies, the fabricator resource removes a combination of the injection molded part and the mold fabrication element. The fabricator resource separates the mold fabrication element from the injection molded part for further processing and use of the injection molded part.Type: GrantFiled: April 2, 2015Date of Patent: November 6, 2018Assignee: Sensata Technologies, Inc.Inventor: Keith R.
