Abstract: A method for locating, via ultra high frequency, a mobile device (T) for “hands-free” access to a vehicle (V), via a locating device (D?) on board the vehicle (V), the locating device (D?) including an ultra high frequency transceiver (10?), an electrical power supply source (Vcc) and an antenna (A?), the locating method being noteworthy in that the transceiver (10?) is disconnected from the antenna (A?), and that the transceiver (10?) is connected to an attenuation module (M1, M2, M3) located at a predetermined distance (L1, L2, L3) from the transceiver (10?) and including an impedance (Z1, Z2, Z3) of predetermined value connected to ground, the predetermined distance (L1, L2, L3) between the transceiver (10?) and the attenuation module (M1, M2, M3) and the predetermined value of the impedance (Z1, Z2, Z3) defining an area (A1, A2, A3) for locating the mobile device (T) around the vehicle (V).

Abstract: A self-adaptive method for assisting tire inflation enables control of tire inflation. If the vehicle stops, the central unit of a TPMS (Tire Pressure Monitoring System) can change in a self-adaptive manner from the reception configuration of the “moving” mode at a high bit rate to a “stationary” mode at a low bit rate. At the same time, if there is a variation in the pressure of a tire, the corresponding wheel unit is set for transmission in “stationary” mode at a low bit rate. The power Pa received at the central unit varies according to a curve (20) which shows, in the illustrated example, two positions of poor reception. By replacing high bit rate transmission with low bit rate transmission, the signal/noise ratio is improved and there is a gain in reception sensitivity of about 5 dB, and the risks of disturbance of the received power are virtually eliminated.

Abstract: A method and apparatus for washing a dog by means of agitation. The agitation is accomplished by placing the dog in a whirlpool of warm water, which periodically reverses direction, therefore creating the same type of scrubbing effect as in a home washing machine, but without a solid agitator shaft in the middle or any solid bodies touching the dog. Soap and conditioner may be dispensed into the whirlpool at various times during the process to assist in further cleaning and conditioning depending on which type of cleaning cycle the operator chooses on a control panel.
