  • Publication number: 20210406858
    Abstract: According to one embodiment, a stocking support system includes a processor configured to acquire a reference display value and a lower limit display value for an item. The processor then acquires a sales number for the item from a sales data processing device and calculates a restocking number for the item when a displayed number of the item falls below the lower limit display value. The processor then instructs a printing device to output the calculated restocking number for the item along with information for identifying the item in a work unit for an item restocking process.

  • Patent number: 11190041
    Abstract: According to an embodiment, a charge-discharge control apparatus includes a rectifier-voltage decrease detector circuit and an over-discharge suppression controller circuit. On the condition that the rectifier-voltage decrease detector circuit detects that voltage output from a rectifier circuit of a power-receiving device is decreased below a voltage threshold, the over-discharge suppression controller circuit suppresses over-discharge of an inverter circuit of a power-feeding device, or suppresses over-discharge of a battery of the power-receiving device.
