Patent number: 11018843Abstract: A restraint control module is provided in this disclosure. The restraint control module is configured to communicate a sync pulse to a sensor. The control module may include a sync pulse driver circuit and a memory. The memory may store the waveform profile of a sync pulse. The sync pulse driver circuit generates a sync pulse in response to the waveform profile stored in the memory. The sync pulse may be transmitted to one or more sensors. The waveform profile stored in the memory may be derived from a sync pulse with reduced electro-magnetic emissions by applying spectrum analysis.Type: GrantFiled: April 4, 2019Date of Patent: May 25, 2021Assignee: VEONEER US, INC.Inventors: Vincent Colarossi, Grant Scott, Stuart Koch, Michael C.

Patent number: 10618791Abstract: A puncturing device for pressurized containers comprises an elongated housing member defining an elongated cavity with openings at first and second ends thereof for receiving an inverted pressurized container at the first end, the housing member including an attachment member for securing the second end of the housing member to a collection receptacle. A non-sparking puncturing member, is mounted within the housing member for piercing a nozzle-end of the pressurized container at its domed top. A counter records each action of the puncture pin. Gases and residual contents are released into the receptacle through the hollow core of the puncture pin. An auxiliary support member is mounted on the housing member for stabilizing relative movement between the housing member and the receptacle. A force-applying apparatus is mounted on the housing member for forcing the pressurized container onto the puncture pin.Type: GrantFiled: December 18, 2017Date of Patent: April 14, 2020Assignee: JUSTRITE MANUFACTURING COMPANY, LLCInventors: Michael C.

Patent number: 9808842Abstract: A puncturing device for pressurized containers comprises an elongated housing defining an elongated cavity with openings at either end for receiving an inverted pressurized container at one end, the housing including a selective attachment member for securing the other end of the housing to a collection receptacle. A non-sparking puncturing apparatus, with a lever having a built-in stop, is movably mounted on the housing with a pivot-link-driven puncture pin extending through an intermediate aperture into the cavity for piercing a nozzle-end of the pressurized container below an internal shoulder thereof with a seal. A counter records each action of the puncture pin. Container contents are released into the receptacle. An auxiliary support is rotatably mounted on the housing for stabilizing relative movement between the housing and the receptacle. A force-applying apparatus is mounted on the housing for engaging the pressurized container and holding it on the seal.Type: GrantFiled: August 18, 2011Date of Patent: November 7, 2017Assignee: JUSTRITE MANUFACTURING COMPANY, L.L.C.Inventor: Michael C.
