20090066497 | Automotive Tire Pressure Monitoring System - An automotive tire pressure monitoring system is provided including a group of tire pressure monitor sensors each comprising a pressure sensor element, a dual-axis accelerometer, and a transmitter generating a pressure signal including accelerometer information. A front antenna and a rear antenna are both in communication with a tire pressure monitoring receiver. The tire pressure monitoring receiver includes logic adapted to: determine a pressure signals left/right designation from the accelerometer information and determine a pressure signal's front/rear designation using comparative signal strength from the front antenna and the rear antenna. | 03-12-2009 |
20090315672 | METHOD OF PROGRAMMING A WIRELESS TRANSMITTER TO A WIRELESS RECEIVER - A wireless remote control system includes a wireless receiver having a normal operating mode in which the wireless receiver may be actuated by a wireless transmitter programmed to the wireless receiver and a programming mode in which the receiver is placed to learn a new wireless transmitter and programming information for the new transmitter is sent to the wireless receiver. Programming a wireless transmitter to the wireless receiver includes actuating the receiver with an existing transmitter already programmed to the receiver, and repeating the actuation of the receiver in a predetermined sequence. In response to the receiver receiving the predetermined sequence of actuations, the receiver enters the programming mode. Programming information for the new transmitter is sent to the receiver, and the receiver programs the new transmitter to the receiver. | 12-24-2009 |
20100102924 | REMOTE CONTROL SYSTEM AND A METHOD OF CONTROL - A remote control system and a method of control. The system includes a control module that facilitates execution of a set of functions, a remote control device that wirelessly communicates with the control module, and an input signal. The input signal is provided to the control module and includes data that is associated with ambient lighting. Polling of the remote control device by the control module is deactivated for a subset of the set of functions when the data is indicative of sufficient ambient lighting. | 04-29-2010 |
20100244768 | AUTOMOTIVE FOB SYSTEM - An automotive fob system may include an automotive fob and a fob charging receptacle. The automotive fob may have a loop feature, and include a power storage unit and a first inductive coil electrically connected with the power storage unit. The first coil may form a loop and be disposed in the loop feature. The fob charging receptacle may include a magnetic core configured to be inserted into the loop feature, and a second inductive coil wrapped around the core. The second inductive coil may be adapted to receive electrical current from a remote power source if electrically connected with the remote power source. | 09-30-2010 |
20100245038 | AUTOMATIC WALK-AWAY DETECTION - A method and system for walk-away locking of a vehicle. The vehicle may be automatically locked when an occupant walks away from the vehicle in a passive manner. The automatic locking capabilities may be incorporated within an energy conservation strategy that allows one or more vehicle components and a fob to enter a sleep mode or otherwise become inactive at particular intervals when signals necessary to automatically locking the vehicle are less likely. | 09-30-2010 |
20110133962 | COMPASS BASED CAR LOCATOR - A remote keyless entry system is provided comprising a handheld remote keyless entry transmitter in selectable wireless communication with a car based entry system. The handheld remote keyless entry transmitter comprises an integrated electronic compass element and logic adapted to store a first compass direction when activated and directed towards a destination. The logic further is adapted to display a return compass direction and a return distance from the car based entry system when activated leaving the destination. | 06-09-2011 |

20080197987 | Keyless entry multi-channel RKE system - A remote keyless entry system includes a portable communication device for communicating with an electronic control module of a transportation vehicle. The transmitter has at least two selectable communication channels for broadcasting communications signals to the transportation vehicle. A vehicle based electronic control module communicates with the portable communication device. The electronic control module includes a receiver that includes at least two selectable communication channels for receiving RF signals from the portable communication device. A controller selectively energizes the receiver for measuring a RSSI voltage level of each selectable communication channel of the receiver over respective predetermined time periods. The controller determines which of the at least two selectable communication channels includes a lowest noise level based on the measured RSSI voltage level. A channel status update signal is broadcast from the electronic control module to the portable communication device identifying the selected communication channel having the lowest noise level. | 08-21-2008 |
20090066496 | LOW FREQUENCY RECEIVER FOR A TIRE PRESSURE MONITOR SYSTEM - A tire pressure monitoring (TPM) system for a vehicle is provided. The system comprises a TPM receiver, a trigger device and a TPM sensor. The TPM receiver is adapted to receive tire pressure information. The trigger device is adapted to generate a low frequency (LF) unmodulated signal that is indicative of trigger command. The TPM sensor comprises an LF tank circuit adapted to receive the LF unmodulated signal and a microprocessor operably coupled to the LF tank circuit and configured to detect the presence of LF unmodulated signal and to transmit a LF output signal having tire pressure information to the TPM receiver in response to the trigger command without demodulating the LF unmodulated signal. | 03-12-2009 |
20090112390 | Method and System for Detecting Installation of an Unmonitored Tire on a Vehicle - A tire pressure monitoring system includes sensors respectively associated with tires normally installed on a vehicle. Each sensor transmits a sensor signal indicative of a parameter of the associated tire to a controller. The signal strength of each sensor signal as received by the controller varies over time when the tire is rolling and remains constant over time when the tire is stationary. The controller generates a received signal strength indicator (RSSI) signal indicative of the signal strength of each sensor signal as received by the controller. The controller processes the RSSI signals along with a speed signal indicative of whether the vehicle is moving or is stationary to determine if any tire is stationary while the vehicle is moving, and generates a warning indicative of an unmonitored tire installed on the vehicle in place of a tire upon determining that the tire is stationary while the vehicle is moving. | 04-30-2009 |
20110170590 | POWER REGULATOR - Method and system of power regulating, such as but not limited to attenuating signal power levels. The power regulating being suitable for use in any number of application, environments, and circuits, including but not limited to those associated with a universal garage door opener (UGDO), remote keyless entry (RKE) unit, tire pressure monitor (TPM) unit, and/or a passive entry element. The regulating may be suitable for directly broadcasting the regulated signal and/or communication the regulated signal to other circuit element for further processing. | 07-14-2011 |
