International Classification:

H04Q 9/00
H02G 3/00
G01R 31/28
H04L 25/08

US Classification:

340 572, 340 564, 307 101, 307 103, 714699, 375346, 4553431

Abstract:

A remote keyless entry (RKE) circuit () and method reduces the amount of current draw by duty cycling the RKE circuit () to ensure that a microcontroller () in the RKE circuit () is awakened only when needed to evaluate RF data. A total operating period for the RKE circuit () includes a transient period, a data monitoring period, and a sleep period. The RKE circuit () includes a pulse blocking circuit () that prevents a receiver stabilization pulse from waking up the microcontroller (). If no data is received during the data monitoring period, the microcontroller () remains in a sleep mode for the remainder of the operating period.

Appl. No.:

10/993066

Inventors:

Brian Farrell - Troy MI, US

Assignee:

Continental Automotive Systems US, Inc. - Auburn Hills

International Classification:

G06F 7/04

US Classification:

340 572, 340 564, 340 101, 34082569, 34042636, 340447

Abstract:

A device and method detects two different types of data, such as tire pressure monitoring system (TPMS) data and remote keyless entry (RKE) data and reduces current draw by duty cycling a receiver in the device asynchronously to intersperse multiple RKE sniffing periods in between consecutive, longer TPMS/RKE sniffing periods. The asynchronous duty cycle ensures that the sniffing periods conform to the actual length of the RKE data and TPMS data periods more closely, minimizing the likelihood of false wakeups caused by noise output by the receiver.

International Classification:

H03L 7/00

US Classification:

331 2, 331176, 331 46, 331 47, 331 49

Abstract:

A real time clock assembly includes paired crystal oscillators that experience changes in frequency responsive to temperature. The differences in frequency changes between the paired crystal oscillators are utilized to determine a temperature utilized to compensate for those shifts in frequency. The predictability of frequency responsive to temperature variations by the paired crystal oscillators is utilized for the determination of temperature.

International Classification:

H04B 1/06

US Classification:

701 36, 342 82

Abstract:

A communication for a vehicle () has a first transmitter () for transmitting a first signal relating to a first vehicle system () and a second transmitter () for transmitting a second signal relating to a second vehicle system (). (FIG. ) A single receiver () has a first reception mode () and a second reception mode (). The first reception mode () is receptive to the first signal while the second reception mode () is receptive to the second signal. A control unit () switches the receiver () between the first reception mode () and the second reception mode ().

Appl. No.:

12/035634

Inventors:

John R. Costello - Rochester Hills MI, US
Jean-Christophe Deniau - Fenton MI, US
Brian Farrell - Troy MI, US

Assignee:

Continental Automotive Systems US, Inc - Auburn Hills MI

International Classification:

B60C 23/00
G08C 19/00

US Classification:

340447, 3405391, 34082569, 34082572, 341176

Abstract:

A tire pressure monitoring system includes a receiver for processing signals and alerting an operator of the vehicle should conditions within any of the tires fall outside a desired range. The transmitters within the tires emit shorter transmission signals during operation by eliminating transmission of the identification code. The receiver stores the identifier for each transmitter for comparison to subsequent transmissions. Subsequent transmissions do not include the identifier. The receiver combines the saved identifier with the value provided in the check portion of the incoming transmission. If the combination of the saved identifier with the value provided in the check portion meets a defined criteria, than the signal is recognized as originating from one of the transmitters.

Appl. No.:

13/206358

Inventors:

Jean-Christophe Deniau - Fenton MI, US
Brian J. Farrell - Troy MI, US

Assignee:

Continental Automotive Systems, Inc. - Auburn Hills MI

International Classification:

B60C 23/00

US Classification:

340447, 340442, 73146, 731462

Abstract:

A determination is made as to whether a frame to be transmitted according to a first protocol is susceptible to being incorrectly interpreted by a receiver in a vehicle as being transmitted according to a second protocol. When the frame is determined to be susceptible to an incorrect interpretation, an internal value of the frame is adjusted, and the adjustment is effective to prevent an incorrect interpretation of the frame being transmitted from the tire pressure monitor to the receiver. The adjusted frame can then be transmitted.

Abstract:

An apparatus for transmitting tire pressure signals includes a transmission buffer and a transmitter. The transmission buffer is configured to store tire pressure monitoring data. The transmitter is configured to transmit a signal including the tire pressure monitoring data. The signal includes a burst that includes plurality of frames and each of the frames includes the tire pressure monitoring information. A plurality of pause spaces is disposed between at least some of the frames in the burst.

International Classification:

H04L 27/06

US Classification:

375316

Abstract:

A tire pressure monitoring system includes a process of reconstructing a complete data frame from portions of partially received data frames. The tire pressure monitoring system includes a receiver that includes a buffer to store portions of the transmissions for reconstruction of data in response to portions of the transmission not being received. A reconstructed data frame is generated using the saved partially received data frame and the currently received partial data frame.
