Device, system and method, in a vehicle communication system, to transmit wirelessly a message comprising the position, heading and speed of a vehicle or other moving object, wherein the transmission is repeated at regular intervals in a temporarily fixed time slot within a predetermined basic time interval. In a key embodiment the message duration is equal to or less than a predetermined time slot duration. Embodiments use generally the same time slot in a contiguous sequence of basic time intervals. Algorithms are described to resolve wireless interference within a time slot. Embodiments divide the basic time interval in multiple durations, “class regions,” for different message classes. Embodiments use different wireless bandwidth allocation algorithms for the class regions.

The method of reducing contamination of electrical signals recorded in the presence of repeated interference contamination comprises obtaining an electrical signal recorded in the presence of a contaminating signal, and detecting a timing signal that occurs at a fixed time point during the electrical signal relative to the onset of the contaminating signal. The electrical signal is digitized, wherein the digitizing begins with the timing signal. A plurality of digitized electrical signals is analyzed, wherein the electrical signals are synchronized with respect to the timing signal, to obtain an estimated contaminating signal that is subtracted from the digitized electrical signal. This method can be used with electrophysiological signals, such as EEG, ECG, EMG and galvanic skin response, and for elimination of noise associated with concurrently used methods such as MRI. The method of noise reduction is applicable to recordings of other electrical signals, including audio recordings.

A price-time relationship for the ad avail is specified by the seller such that the price of the ad avail varies over the fixed time period. The server node matches the request to the offer at time t₁ during the fixed time period and the server node computes a price for the ad avail based on t₁ using the price-time function.

A sensing system collects position data associated with one or more obstacles within a certain range of a vehicle. A former establishes an occupancy grid based on the collected position data. A motion monitoring module determines a reaction distance and a deceleration distance associated with a vehicle at a regular time interval during an operational state. A safety guidance module establishes a safety zone (e.g., safety zone grid) for the regular time interval based on the occupancy grid, the determined reaction distance, and the deceleration distance.

A method and an apparatus are provided for securely identifying a mobile user while avoiding trackability of his/her movements, i.e. it provides a way for a secure user identification in secrecy. The gist is to encrypt the user's identifier, and/or his/her password, and a synchronization indication, preferably a fixed time interval, under a secret one-way function and sending the encrypted message, called a "dynamic user identifier", to the user's "home authority" where he/she is registered. The home authority comprises correspondence tables listing, pre-computed for every time interval (or another chosen synchronization), the dynamic user identifiers and the corresponding true identity of the user and can thus quickly decide whether the received encrypted message originates from a registered user. On the other hand, an intruder is neither able to detect from the encrypted messages the identity of the user nor can he/she track a user's moves.

A system and method for simultaneously updating a plurality of user interface elements displayed in a web page at a periodic time interval. In response to a web browser accessing the web page, the web server generates information for displaying the plurality of user interface elements in the web page and generates scripting code associated with the user interface elements. When the web browser displays the web page, the scripting code starts a timer that periodically elapses at fixed time intervals. Each time the timer elapses, the scripting code asynchronously communicates with the web server to receive update information for updating the user interface elements. Exemplary re-useable software components for implementing the simultaneous update of a plurality of user interface elements in a web page are described.

A method and computer program product for providing survivor income-replacement benefits having a guaranteed rate of interest with the possibility of a higher income stream to the designated survivor if supported by prevailing interest rates at the time of annuitization. In one embodiment, the insured would purchase either a fixed level dollar amount of monthly income for a fixed period of time or a Cost of Living Adjusted (COLA) benefit in the form of a monthly annuity. The insurance carrier is required to contractually guarantee a minimum rate of interest, e.g., 3% at the time of annuitization. The insurance carrier is further required to apply the same discount rate to the annuity contract that is provided to the best commercially available immediate annuity contract the carrier offers at the time of annuitization, subject to the minimum guaranteed rate of interest. Thus, the beneficiary may receive an increased income stream if the relevant interest rate at the time of the purchaser's death exceeds the guaranteed minimum interest rate. Thus, if the insured purchased a survivor benefit under the inventive method with a 3% guaranteed minimum COLA, and if the best commercially available immediate annuity interest rate is 6%, the benefit paid the beneficiary survivor is increased annually at a rate of 6%. Without COLA, the contract simply starts paying higher level monthly benefits based on the higher 6% discount rate.

Methods to set a viewing and/or listening term are classified into two types, which are a fixed-time-length type to limit time length and a fixed-expiration-time type to limit expiration time. And the timings of license acquisition are classified into two types which are an immediate-acquisition type and a point-of-use type. The type of the timing of license acquisition is written to a meta data which is to be sent to a terminal before initiating download. The terminal determines the timing of license acquisition according to the meta data. When contents are point-of-use type, the terminal doesn't acquire a key and an expiration time information until a time of initiating playback. On the other hand, when contents are immediate-acquisition type, the terminal acquires the key and the expiration time information at any point of time. Since the key is acquired at the early timing such as download completion timing, a reaction velocity in response to a playback instruction can be heighten.

A sensor transmits and receives wireless signals at intervals. A sensor unit, a processor 130, a wireless transmitter circuit, and a wireless receiver circuit are activated in sequence only for a fixed time when the electric power generated by a generator circuit and charged in a capacitor reaches a preset level. Sensing information detected by the sensor unit is processed by the processor circuit and, information on the number of receivable bytes is added to the processing results in the wireless receiver circuit. This added information is sent as sensor information to the wireless host from the wireless transmitting circuit, and the wireless receiver circuit that activated after the wireless transmitter circuit was activated, receives a control information signal from the wireless host. This received information is processed in the processor circuit.

A cyclic prioritized multiple access (CPMA) method is disclosed which includes Fixed Deterministic Post-Backoff. Fixed deterministic post-backoff reduces conflicts between access points of overlapping cells. Contention-free sessions (CFSs) can be generated, one from each overlapping cell. Each active access point engages in a fixed deterministic post-backoff. A fixed deterministic backoff delay (Bkoff times a fixed number of idle time slots) is used by all access points, with the value of Bkoff being greater than the number of overlapping cells. The Bkoff should be large enough to enable the traffic that needs to be accommodated by the channel. Each access point has a backoff timer that is counted down using the shortest interframe space possible, typically the Priority Interframe Space (PIFS). A contention-free session (CFS) is initiated when the backoff timer expires, and it is then reset to the value of Bkoff to start a new cycle. A cycle is measured in terms of idle time slots instead of a fixed time interval. Contention-based transmissions can be attempted by an access point or other stations in the cell using their assigned priority while the access point is counting down its backoff timer. A new access point can get started and resolve possible collisions by a small random backoff. Subsequent contention-free sessions (CFSs) will not conflict, given an existing sequence of non-conflicting CFSs, since the follower access point's backoff delay exceeds that of the leader's by at least one times the fixed number of idle time slots. In this manner, contention-free sessions can be conducted without interference in the first and second cells.
