摘要： A method and apparatus are disclosed for determining the product of N numbers in base Z. The method includes the steps of: (1) providing a first and succeeding storage arrays. The first storage array includes storage loci containing indicia of products of a first digit and a second digit. A first pointer is positioned by the first digit, a second pointer is positioned by the second digit, and the pointers cooperate to identify a first solution locus containing a first product. Succeeding storage arrays are associated with succeeding N numbers. The first and second pointers identify a subset of storage loci in a succeeding storage array. A third pointer associated with a third digit identifies a second solution locus among the subset. Each array's pointers cooperate to designate a next-succeeding array and a subset of storage loci, and each next-succeeding array has a pointer associated with a next digit to designate a next solution locus until N numbers are involved in the product. Each succeeding array stores indicia of the product of the digit of the number associated with that array and the product identified by the preceding array; (2) determining a partial product for each combination of the digits of each of the N numbers, each partial product having a combinational significance established by the significance of each digit involved; (3) accumulating partial products in hierarchically arranged cells according to a particular relationship; and (4) effecting a shifting accumulation operation among the cells.

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.
