A phased-array includes, in part, N transceivers each including a receiver and a transmitter, and a controller. The phased array is configured to transmit a first radio signal from a first element of the array during a first time period, receive the first radio signal from a second element of the array, recover a first value associated with the radio signal received by the second element, transmit a second radio signal from the second element of the array during a second time period, receive the second radio signal from the first element of the array, recover a second value associated with the radio signal received by the first element, and determine a first phase of a reference signal received by the second element from the recovered first and second values. The first phase is relative to a second phase of the reference signal received by the first element.

A resilient collapsible tube for dispensing viscous material has an elastic device for retaining the tube in progressively rolled positions as the contents of the tube are dispensed. The elastic retaining device defines elastic loops extending longitudinally around the tube.
