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 |
20080238637 | WIRELESS ACCESS SYSTEM AND METHOD - The disclosed embodiments include a wireless access system and method that enable the transmission of wireless access signals having a desired power level.

20090009303 | COMMUNICATION SYSTEM FOR VEHICLE - A communication system for a vehicle includes a portable identification device including a portion for receiving an interrogation signal and a portion for transmitting an indication indicative signal responsive to the interrogation signal, multiple tire sensor devices each of which includes a portion for receiving an initiation signal and a portion for transmitting a condition indicative signal responsive to the initiation signal, multiple transmitting devices each of which emits the interrogation signal and the initiation signal for different conditions within a communication area, a receiving device for receiving the indication indicative signal and the condition indicative signal, and a central controller for unlocking a door lock device when the portable identification device is determined to be in an overlapped area based on a condition of the portable identification device, the overlapped area being defined between two adjacent communication areas and in which the door lock device is involved. | 01-08-2009 |
20090021357 | Wireless and keyless vehicle entry alarm alert system - A wireless keyless entry system can lock, unlock automotive doors, trunks, etc. without the use of an ignition key and can disarm an onboard anti-theft alarm system or in the alterative can trigger the alarm as a deterrent. The novelty of this invention relates to the fact that the owner of the vehicle is unaware of an alarm state triggered at the vehicle if the owner is out of eye sight and or ‘ear shot’ of the vehicle. The new wireless and keyless entry system would include an RF transmitter in the vehicle that would transmit a unique code when the vehicle is in an alarm state. The unique signal would be received by a portable receiver/controller carried by the owner/operator of the vehicle, triggering a visible light; an audible alarm, pulsing or steady; and/or a vibrator alerting the owner to investigate the automotive alarm emanating from the vehicle. | 01-22-2009 |
20090091434 | TUMBLER TYPE LOCK APPARATUS - A tumbler-type lock apparatus for use with a tumbler-type card key having a code pattern region including an array of holes and non-hole portions that expresses a key code of the tumbler-type card key. The tumbler-type lock apparatus includes a slider case and a slider movable relative to the slider case when the tumbler-type card key is inserted into the tumbler-type lock apparatus. Tumblers extending in the slider case and slider each correspond to one of the holes or non-hole portions. Springs bias the tumblers towards the slider. The tumbler-type lock apparatus verifies the tumbler-type card key when the tumblers are engaged with the slider case and slider during insertion of the tumbler-type card key. The slider includes accommodation portions. A distal end of the tumbler that has passed through the corresponding hole of the tumbler-type card key is accommodated in the corresponding accommodation portion. | 04-09-2009 |
20090115585 | SECURITY ACCESS SYSTEM, APPARATUS, AND METHOD - A security access system and method is disclosed. In one embodiment, a vehicle access security system, comprising a transmitter element, a detector element, a receiver element, and a computational element is taught, wherein the transmitter element transmits a modulated vehicle access signal into a predetermined communications channel, which is detected by the detector element. The detector element is adapted to detect the modulated vehicle access signal and further adapted to have a detector output signal. The receiver element receives the detector output signal and performs at least one signal processing function, wherein the receiver element has a receiver output signal. The computational element accepts the receiver output signal and compares it to a predetermined access code to determine whether a user shall be granted access to the vehicle. | 05-07-2009 |
20090243821 | Vehicle key fob with scanning device and display - An apparatus and method for capturing and displaying images in a vehicle RKE fob includes an imager carried on the fob for capturing images for storage in a memory coupled to a fob control. The stored images are viewable on a display on the fob and are scannable for commercial use. The imager may provide one or more axis movement of the display by movement of a user's finger over the image control display and selection of stored images. The imager and image memory storage may also be used for biometric data comparison. | 10-01-2009 |
20100102943 | Wireless Touch Sensor - A passive keyless entry system is provided comprising a wireless touch sensor, a RFID tag, a security system, a sensor antenna connected to the security system that receives a sensor signal from the wireless touch sensor, and a tag antenna connected to the security system that receives a tag signal from the RFID tag. The security system unlocks a locking mechanism when both the sensor signal and the tag signal are received by the security system. Preferably, the RFID tag comprises an active RFID chip. | 04-29-2010 |
20110298600 | COMMUNICATION SYSTEM FOR VEHICLE - A communication system for a vehicle includes a portable identification device including a portion for receiving an interrogation signal and a portion for transmitting an indication indicative signal responsive to the interrogation signal, multiple tire sensor devices each of which includes a portion for receiving an initiation signal and a portion for transmitting a condition indicative signal responsive to the initiation signal, multiple transmitting devices each of which emits the interrogation signal and the initiation signal for different conditions within a communication area, a receiving device for receiving the indication indicative signal and the condition indicative signal, and a central controller for unlocking a door lock device when the portable identification device is determined to be in an overlapped area based on a condition of the portable identification device, the overlapped area being defined between two adjacent communication areas and in which the door lock device is involved. | 12-08-2011 |
20110309922 | LOW LATENCY INSIDE/OUTSIDE DETERMINATION FOR PORTABLE TRANSMITTER - A method and system is disclosed for determining presence of a portable transmitter relative to a boundary.
