摘要： An integrated circuit comprises a frequency detector. The frequency detector comprises a timer state machine unit operably couplable to a timer and arranged to receive an incoming carrier signal; determine whether the incoming carrier signal comprises a valid frequency; generate a valid carrier indication when the incoming carrier signal is determined as having a valid frequency; and adjust the timer between at least a first timing mode of operation and a second timing mode of operation of the frequency detector in response to the determination.

摘要： A method of detecting a transmission fault of a wheel unit belonging to a tire pressure monitoring system which includes a plurality of wheel units associated with a central unit placed in the vehicle. The method includes: a) transmitting messages by the wheel units, b) receiving these messages by the central unit having an active antenna exhibiting a plurality of reception lobes each able to receive a message originating from a predetermined wheel unit, c) when a lobe has received a message originating from the wheel unit with which it is associated, deactivating this lobe, d) repeating steps b) and c) until all the lobes have received a message, e) if after a predetermined time span all the messages of all the wheel units have been received, all the lobes are reactivated, in the converse case the wheel units whose messages have not been received are counted “mute”.

摘要： A method for temporarily inhibiting, when it is detected inside a locked vehicle, a portable remote control unit, known as a tag, of a keyless entry device designed to implement access authorization procedures to allow access to the vehicle, these including an initial identification procedure which includes causing a central processing unit to periodically transmit a data frame incorporating a preamble consisting of a predefined wake-up code that can be identified by the tag. The inhibition method include defining a first wake-up code at least intended for the procedure of temporarily inhibiting the tags, and a second wake-up code specifically intended for the procedure of identifying the tags, and in setting up temporary inhibition procedures which consist in causing a specific data frame incorporating, in its preamble, the first wake-up code and designed to deactivate the recognition, by each target tag, of the second wake-up code, to be transmitted.
