In some implementations, a computer-implemented method includes storing a plurality of acceleration profiles in a mobile device; receiving accelerometer data from an accelerometer in the mobile device; correlating the accelerometer data with one accelerometer profile in the plurality of accelerometer profiles; and activating a user application of the mobile device that is associated with the correlated accelerometer profile. Each acceleration profile can correspond to a sequence of acceleration forces a mobile device would be subjected to when carried with a user during an activity that corresponds to the correlated acceleration profile.

A method of controlling packet traffic in an IP network of originating, receiving and intermediate nodes to meet performance objectives established by service level agreements. Traffic statistics and performance data such as delay and loss rates relating to traffic flows are collected at intermediate nodes. A control server processes the collected data to determines data flow rates for different priorities of traffic. A static directory node is used to look up inter-node connections and determine initial traffic classes corresponding to those connections. The rates are combined with the initial traffic classes to define codes for encoding the headers of packets to determine their network priority.

A wheel vibration information signal detected by an acceleration sensor (11) mounted on a wheel (1) or an in-tire gas pressure fluctuation information signal detected by a pressure sensor (31) mounted in a tire is subjected to frequency analysis by frequency analysis means (14 (34)), so as to detect the vibration spectrum or the pressure fluctuation spectrum band value. The vibration level of the detected band is compared to a vibration level correspondence table (15T) showing the relationship between the road surface friction coefficient μ stored in the vibration level storage means (15) and the vibration level. Alternatively, the detected pressure level is compared to a pressure fluctuation level correspondence table (35T) showing the relationship between the road surface friction coefficient μ stored in the pressure fluctuation level storage means (35) and the pressure fluctuation level. Thus, it is possible to accurately estimate the value of road surface friction coefficient μ, thereby improving the vehicle safety.

The output level (or vibration level) of the vibration, as detected by a vibration sensor (11) disposed at the underside of a vehicle spring, of the underside is frequency-converted by frequency analyzing means (14F) to determine the frequency spectrum of a vibration level. The vibration levels of at least two frequency bands of the determined frequency spectrum are computed by a vibration level computing means (14R). This computed value of the vibration level and the frequency spectral master curve of the vibration level, as stored in advance in vibration level storage means (16S), are compared to estimate the road surface state and the running state of the vehicle. On additional, a multi-function sensing system is constructed for estimating a road surface state and a tire running state with one sensor, by detecting the running state of the tire including the tire air pressure from the vibration level of the underside of the vehicle spring to estimate a vehicle running state.

An amount of data to be distributed to each receiving terminal is dynamically controlled for each receiving terminal in response to a congestion of each of plural receiving terminals. When a determination of an RR (Reception Report) returned from the receiving terminal results in a very low rate of packet loss, an adaptive control mixer distributes communication data transmitted from a transmitting terminal to the receiving terminal without reducing the communication data. On the other hand, the determination of the RRs returned from the receiving terminals results in a high rate of packet loss, for example, 50% and 90%, respectively. In this case, the adaptive control mixer reduces, for example, 50% of the communication data transmitted from the transmitting terminal and then distributes the data to the one receiving terminal. The adaptive control mixer reduces, for example, 90% of the communication data and then distributes the data to the other receiving terminal.

PROBLEM TO BE SOLVED: To improve vehicle traveling safety by precisely estimating the condition of a road surface with a tire brought into contact therewith without being affected by disturbance even in the steady traveling condition wherein the operation such as braking, driving and steering is applied thereto. SOLUTION: While vibration in peripheral and diameter directions of the tire is detected by a two-directional vibration sensor 11 mounted on a tire air chamber side of a tire tread, peak values P A , P B of vibration level in the vicinity of a grounding start point or a grounding completion point of the vibration in the peripheral and diameter directions of the tire are detected in a peak level detecting means 14. The peak ratio R=P A /P B , which is the ratio of the peak values P A , P B , is calculated by a road surface friction coefficient estimating means 15. A road surface friction coefficient μ is estimated from the calculated peak ratio R by using a map 16M indicating the relation between the peak ratio R and the road surface friction coefficient μ previously stored in a storage means 16.
