A weighing device includes at least one weighing cell (3) disposed in a weighing cell housing (5) and a control cabinet (1). The control cabinet (1) includes a gas pressure control (7) to which can be connected a source with gas overpressure (9). The control cabinet (1) includes an outlet opening (11) through which the gas can exit. The control cabinet (1) is connected with the weighing cell housing (5) through a first connection (13) for supplying gas into the weighing cell housing (5), and through a second connection (15) for gas removal from the weighing cell housing (5). The gas pressure connection (7) is connected with the first connection (13) through a flow guide means (17), so that at least one part of a supplied gas first flows through an interior of the weighing cell housing and subsequently it exits through the outlet opening (11) of the control cabinet (1).

An emergency readiness verification system includes a housing, a secure weight-sensing mechanism, a vertically-actuated switch assembly, a vertically-adjustable calibration mechanism, and an alert device in communication with the vertically-actuated switch assembly. The vertically-adjustable calibration mechanism fixes a vertical position of the vertically-actuated switch assembly such that an engagement tab of the attachment extension engages an actuator of the vertically-actuated switch assembly when a weight of the fire extinguisher supported by an extinguisher attachment falls is within an alert threshold, and disengages the actuator when the weight of the fire extinguisher falls below the alert threshold or when the fire extinguisher is not supported by the extinguisher attachment.

A modular wireless scale system comprising microscales comprises a master scale that may be configured to be used with one or more slave scales. The master scale includes a heavy load cell and a light load cell disposed on opposite sides of a cuboid master housing. The master scale housing encloses a master computer-based microcontroller, a wireless transceiver, an accelerometer, and a power source, and may optionally include a display. The master scale may be used as a stand-alone scale for weights up to the maximum weight supported by the heavy load cell and the scale housing. Each of the slave scales includes a heavy load cell supported by a cuboid housing that encloses a slave computer-based microcontroller, a wireless transceiver, and a power source.

Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light source disposed in or on a housing of a scanner-scale for producing a light beam along an edge of the weigh platter, the light beam being modulated to contain a defined packet of data; a detector for receiving the data-modulated light beam, the detector being disposed in or on the housing; and a processor coupled with the detector for decoding the defined packet of data responsive to the detector receiving the data-modulated light beam. Various indicators for alerting the operator of off-scale detection are also described.

A balance assembly having an assembled state and an unassembled state. The balance assembly comprises a base configured to receive a portion of a like base in a nesting relation in an unassembled state of the balance assembly, a pedestal coupled to the base in an assembled state of the balance assembly, the pedestal configured to receive a portion of a like pedestal in a nesting relation in the unassembled state, a lever removably and pivotably coupled to the pedestal about a fulcrum centered along a length of the lever in the assembled state, the lever configured to receive a portion of a like lever in a nesting relation in the unassembled state, and a pair of containers removably supported at opposite ends of the lever in the assembled state, each container configured to receive a portion of a like container in a nesting relation in the unassembled state.

An electronic scale includes: a scale body that has a top surface provided with a weighing tray on which an object to be weighed is to be laid and a display portion which displays a weight of the object to be weighed; and a lid member that is capable of closing the top surface of the scale body and that is capable of opening and closing. A camera that images the top surface of the scale body including the weighing tray and the display portion is provided on the lid member. Alternatively, the camera is provided on the top surface of the scale body and the lid member includes reflection means that reflects an image of the top surface of the scale body including the weighing tray and the display portion toward the camera when the lid member opens, on a surface of the lid member that faces the scale body. The electronic scale is capable of simultaneously imaging the object to be weighed and the displayed weight of the same and eliminates need for a special support structure to support the camera for imaging, and the top surface of the scale body can be closed when the electronic scale is not in use.

A barcode reader has a weigh platter and an off-platter detection assembly. The weigh platter is configured to measure a weight of an object and has a surface extending in a first transverse plane, a proximal edge, a first lateral edge extending non-parallel to the proximal edge, and a distal edge. The off-platter detection assembly includes a light emission assembly and a light detection assembly. The light emission assembly is configured to emit a collimated light beam along the first lateral edge, above the surface. The light diffusing barrier is positioned in a path of the collimated light beam and is configured to diffuse the light beam such that the light diffusing barrier appears to be illuminated when contacted by the light beam and appears not to be illuminated when not contacted by the light beam.
