    摘要: A method for mitigating interference in impulse radio communication conveying a message from a transmitting station to a receiving station. The method comprises the steps of: (a) conveying the message in packets; (b) repeating conveyance of selected packets to make up a repeat package; and (c) conveying the repeat package a plurality of times at a repeat period greater than twice the occurrence period of the interference. The communication may convey a message from a proximate transmitter to a distal receiver, and receive a message by a proximate receiver from a distal transmitter. In such a system, the method comprises the steps of: (a) providing interference indications by the distal receiver to the proximate transmitter; (b) using the interference indications to determine predicted noise periods; and (c) operating the proximate transmitter to convey the message according to at least one of the following: (1) avoiding conveying the message during noise periods; (2) conveying the message at a higher power during noise periods; (3) varying error detection coding in the message during noise periods; (4) retransmitting the message following noise periods; (5) avoiding conveying the message when interference is greater than a first strength; (6) conveying the message at a higher power when the interference is greater than a second strength; (7) varying error detection coding in the message when the interference is greater than a third strength; and (8) retransmitting a portion of the message after interference has subsided to less than a predetermined strength.

    摘要: An improved apparatus for regulating air flow between a cooling unit and a compartment in a refrigeration system includes a first baffle element having an array of first air passages, and a second baffle element having an array of second air passages. The first baffle element and the second baffle element are slidingly engaged and are slidingly positionable with respect to each other. The first air passages and the second air passages cooperate to pass air through the apparatus when the first baffle element and the second baffle element are in a first position, and the first air passages and the second air passages cooperate to substantially block air from passing through the apparatus when the first baffle element and the second baffle element are in a second position. The apparatus further includes an actuator coupled with the first baffle element and the second baffle element for slidingly positioning the baffle elements, the actuator having an actuated state and an idle state. The apparatus further includes a standoff structure for establishing a predetermined separation distance between the first baffle element and the second baffle element proximal to the standoff structure. The first baffle element and the second baffle element are in substantially adjoining relation distal from the standoff structure when the actuator is in the idle state and are substantially the separation distance apart distal from the standoff structure when the actuator is in the actuated state.
