Abstract:
A weighing apparatus comprising: at least two weight sensing elements that each comprise at least:a. a weight sensing base comprising at least one fluid-filled instrument and an analog to digital converter; b. two mounting assemblies supporting and holding each weight sensing base and being connected directly or indirectly to a bed that is being weighed; c. a thermostat mounted within the weight sensing base; d. a heat tape mounted within the weight sensing base; and e. a transformer connected to the heat tape and to the thermostat and mounted within the weight sensing base; such that, when the bed is solely supported by the weight sensing base, any pressure exerted on the fluid-filled instruments is indicative of the weight of the bed and of any objects or living things held or supported by the bed as indicated by the analog to digital converted connected to the fluid-filled instrument.
