Publication number: 20230356550Abstract: A tire monitor includes a sensor generating tire data and a plurality of control modules having phase locked loop circuits. The control modules generate output signals carrying the tire data. A first of the control modules is configured to generate first output signals having a first frequency and according to a first protocol. A second of the control modules is configured to generate second output signals having a second frequency and according to a second protocol. In examples, the output signal can be transmitted in parallel to different computing systems.Type: ApplicationFiled: May 5, 2022Publication date: November 9, 2023Inventors: Nicolas Henriet, Emmanuel Marguet, Ian G. Barrett, Felipe Bianco Pozatoo

Patent number: 9902215Abstract: A tire monitor for mounting on a wheel rim, the tire monitor comprising a housing having a first part (644A) configured to receive a component substrate (645) and a second part (644B) configured to receive one or more other components of the tire monitor, for example a battery. The first and second parts of the housing are non-coplanar and non-parallel with one another. When the tire monitor is mounted on the wheel rim, the substrate is non-coplanar and non-parallel with a plane (T) that is tangential to the wheel rim at the location where the tire monitor is mounted on the rim and preferably the substrate plane is substantially radial with respect to the wheel rim.Type: GrantFiled: April 10, 2013Date of Patent: February 27, 2018Assignee: Schrader Electronics LimitedInventors: Mark Duffy, Samuel Strahan, Philip Dorman, Emmanuel Marguet, Nicolas Henriet, Thomas Guillemin

Patent number: 9333815Abstract: Methods, systems, and devices are provided for tire pressure detectors that may operate according to one of two or more selectable frequencies. Tire pressure detectors may include an RF section to modulate pressure information from a pressure sensor onto an output signal. The frequency of the output signal may be selectable from two or more frequencies based on a frequency required by a vehicle that the tire pressure detector is to be used with. An RF matching circuit may be coupled between the RF section and an antenna, with an impedance of the RF matching circuit selected based of the frequency of the output signal. Such impedance matching may provide a constant power level output from the tire pressure detector independent of the frequency of the tire pressure detector transmissions.Type: GrantFiled: April 15, 2014Date of Patent: May 10, 2016Assignee: Schrader Electronics Ltd.Inventors: Nicolas Henriet, Emmanuel Marguet, Ian Barrett

Patent number: 7916011Abstract: A tire monitor system includes a tire monitor sensor unit that has a tire pressure detector, a coupler and a tire valve. The tire valve operates as an antenna to transmit tire data from the tire pressure detector. The coupler provides a capacitive coupling that removably couples the tire pressure detector and the tire valve. The coupler includes two metal layers separated by a dielectric layer. The two metal layers may be formed by the tire valve and a connection tube.Type: GrantFiled: January 22, 2007Date of Patent: March 29, 2011Assignee: Schrader Electronics Ltd.Inventors: Emmanuel Marguet, Adrian Page

Patent number: 7741964Abstract: A tire pressure detector employs a reduced power consumption mechanism comprising a PLL circuit including a VCO, that is operated in response to the logic states of an input data stream and a power amplifier configured to be externally located to an integrated circuit. The input data stream includes tire pressure information and is configured to be encoded to have multiple logic states. A micro-controller is employed to control the VCO, turning the VCO, and/or the amplifier, on and off for a certain period, according to the pattern of each data bit of the input data stream thus providing reduced current consumption. This tire pressure detector thus embodies an optimized circuit arrangement in terms of power efficiency.Type: GrantFiled: May 31, 2007Date of Patent: June 22, 2010Assignee: Schrader Electronics Ltd.Inventors: Samuel Kane Strahan, Neil Bilcliff, Emmanuel Marguet, Nicolas Henriet

Patent number: 6864785Abstract: In a remote tire monitor system, radio frequency (RF) signals including tire data are transmitted from a plurality of tire monitors at wheels of a vehicle. At an RF receiver, the signals are received and tire data is detected. The RF signals are detected at a receiving RF detector associated with the transmitting tire monitor. The receiving RF detector produces a transmission indication in response to the received RF signals. A control unit is coupled to the RF receiver and the RF detector. The control unit receives the tire data and the transmission indication and associates a position of the transmitting tire monitor with the tire data in response to transmission indication. This permits automatic update of the position of tire monitors on the vehicle.Type: GrantFiled: February 10, 2003Date of Patent: March 8, 2005Assignee: Schrader-Bridgeport International, Inc.Inventors: Emmanuel Marguet, William David Stewart
