Abstract: Bagging systems having rotation mechanisms are disclosed. According to an aspect, a bagging system includes a base that defines an area for placement of a shopping bag. The bagging system also includes a bag support attached to the base and positioned to support the shopping bag in the defined area. Further, the bagging system includes a rotation mechanism that rotatably attaches the bag support to the base with an axis of rotation that is vertically aligned with the bag support.

Abstract: Electronic equipment can be operated in an enclosure wherein the electronic equipment is powered by a DC power source including a rectifier that receives an AC power signal and a battery that provides backup when the AC power signal is interrupted. For example, a DC power signal generated by the DC power source and a temperature in the enclosure for the electronic equipment can be monitored. The DC power signal can be blocked from the electronic equipment in the enclosure when the DC power signal is less than a low voltage threshold for the battery or when the temperature in the enclosure is outside a range of first high and low temperature thresholds for operation of the electronic equipment. The DC power signal can be provided to the electronic equipment in the enclosure when the DC power signal is above the low voltage threshold for the battery and when the temperature in the enclosure is within the range of the first high and low temperature thresholds for operation of the electronic equipment.
