Inventory monitoring systems and apparatuses

A weight scale configured to at least partly support a supplies carrier, the weight scale comprising:

• a weight sensor configured to sense a weight supported by the weight scale;
• a wireless communication transmitter configured to wirelessly transmit signals over a first distance according to a first communication protocol;
• an input device configured to receive input from within a second distance, the second distance being less than the first distance;
• one or more processors in data communication with the wireless communication transmitter, the input device, and the weight sensor;
• memory storing one or more sequences of instructions;
• and
• a housing that houses the weight sensor, wireless communication transmitter, input device, one or more processors, and memory;
• wherein the one or more sequences of instructions stored on the memory are configured to cause the one or more processors to:
• configure, based on the input received by the input device, the wireless communication transmitter for communication of signals according to the first communication protocol;
• receive, from the weight sensor, data representative of the weight sensed by the weight sensor;
• and
• cause the wireless communication transmitter to transmit a signal according to the first communication protocol, the signal being based on the data representative of the weight sensed by the weight sensor, and the signal being transmitted in accordance with the input received by the input device.

A weighing system comprising:

• a plurality of weight scales, each of which is configured to partly support a supplies carrier, the plurality of weight scales being configured to together support the supplies carrier;
• and
• a computing device;
• wherein each particular weight scale of the plurality of weight scales comprises:
• a weight sensor configured to sense a weight supported by that particular weight scale;
• a wireless communication transmitter;
• one or more processors in data communication with the wireless communication transmitter and the weight sensor;
• and
• memory storing timing data and one or more sequences of instructions for causing the one or more processors of the particular weight scale to:
• implement a first clock that is synchronized with one or more second clocks of one or more second weight scales of the plurality of weight scales, the first clock producing timing data;
• compare the timing data of the first clock to the timing data stored in the memory of the particular weight scale;
• based on the comparison, record data representative of the weight sensed by the weight sensor of the particular weight scale within a first time window, wherein the first time window is the same for all weights scales of the plurality of weight scales;
• and
• cause the wireless communication transmitter of the particular weight scale to transmit a signal based on the recorded data;
• and
• wherein the computing device is configured to:
• receive the signals transmitted by the wireless communication transmitters of the plurality of weight scales;
• and
• determine, based on the received signals, a combined weight value representative of a weight of the supplies carrier within the first time window.
