Disclosed is method for controlling interference in a wireless system having multiple sending and receiving nodes. In the method for controlling interference in a wireless system having multiple sending and receiving nodes, a plurality of receiving nodes share each other's channel information, each of the receiving nodes uses the shared channel information to calculate a precoding matrix which is fed back to the sending nodes, and each of the sending nodes uses each of the precoding matrices received as feedback to transmit a send signal to the receiving nodes, thereby controlling interference. Complete interference alignment can be achieved even by just sharing channel information between receiving nodes, and the invention can be employed not only for inter-cell interference but also for intra-cell interference environments.

A unitary projectile for an immobilization weapon and tethered by two electrical wires, has a plurality of electrical contacts including several contacts dispersed in a spaced pattern around the projectile after target impact. The pattern of several contacts substantially increases the probability that if the projectile hits the target, an immobilization circuit through the target will be completed. The deployment of the second contacts occurs as a result of the sudden deceleration of the projectile when it impacts the target or by the use of an additional spring-biased device. This simplifies the deployment as well as the projectile configuration and likely reduces the risk of misactivation or an ill-timed activation of the second contacts. In a preferred version of the disclosed embodiments, each projectile has its own electrical contact which forms one of the two polarities of the electrical discharge. In addition, there are preferably four second polarity contacts dispersed in a symmetrical arrangement around the projectile.

In a speech recognition embodiment, the data entered is selected from an active list containing unique sounding entries. Alternatively, the data entered may be selected by speaking the numbers associated with the keys corresponding to the keystrokes required for data entry.
