  • Patent number: 6180892
    Abstract: An improved mixing scale, such as a paint mixing scale, includes a base which supports a scale pan in a substantially horizontal position. The scale pan supports a receiver container for holding the contents of that which is to be weighed. The mixing scale also includes a backing member which extends upwardly from the base and includes an output display near a top end of the member for presenting the measurement values produced by the scale. Proximate to the output display is a visual flow monitoring device, such as a reflector. Placement of the reflector proximate to the output display allows a user of the mixing scale to monitor the measurement value presentation and the flow of an additive being delivered into the receiver container simultaneously, or at the very least without requiring a physical shift in position by the user which might otherwise disrupt the delivery operation.

  • Patent number: 6038465
    Abstract: A system and a method for remote monitoring of a designated user utilize an integrated scale that is able to measure the body weight of a current user and determine whether the current user is the designated user. The identification of the current user is accomplished by measuring a preselected length of the current user by reflecting sound waves at location(s) that defines the preselected length and comparing the measured length to a corresponding length of the designated user that is stored in the integrated scale. When the current user is identified as the designated user, the integrated scale transmits the measured body weight to a remote monitoring device. The preselected length may be the distance from the bottom of a foot to the knee joint. Alternatively, the preselected length may be the length of a tibia or femur, or the skeletal height.

  • Patent number: 5650596
    Abstract: A device for automatically counting, weighing, and calculating blood loss contained within, soiled surgical sponges includes a cabinet with an opening at the top through which sponges are deposited, a reader which scans each sponge entered and determines sponge type from a tag affixed to each sponge, and a disposable bag into which the sponges are deposited. The disposable bag is removably mounted to a weighing scale; there is also a rear door from which the disposable bag can be easily removed, a rechargeable battery, a shelf for unused disposable bag storage, a control unit which processes data received from reader and scale and instantaneously calculates total weight of liquid contained within sponges entered, a display panel which continuously displays the number and type of sponges entered during a given procedure as well as the total weight of liquids retained in those sponges.

  • Patent number: 5621194
    Abstract: A combinational weighing machine has weigh hoppers for weighing articles, a dispersion feeder for dispersing articles to be weighed, supply troughs for supplying articles from the dispersion feeder to the weigh hoppers and a control unit for controlling overall operations of the machine inclusive of combining weight values outputted from the weigh hoppers and discharging articles from selected ones of these weigh hoppers. The weighing machine is placed inside a washing device which forms a closed chamber inside and covers the weighing machine from all its four sides as well as from above. Nozzles for emitting warm water and a cleaning liquid are provided inside this chamber such that the liquids are prevented from splashing the work areas around the machine. The washing device may be lifted and kept away from the weighing machine during a normal mode of operation of the latter.

  • Patent number: 5593113
    Abstract: A multiple payload system comprising a sling assembly and a frame assembly for suspension from an aircraft. The sling assembly includes an elongated load bearing cable having a first end and a second end. A stress sensor used in measuring the weight of the payloads extends between the aircraft and the first end of the load bearing cable. A payload hook is also attached to the sling assembly with an anti-torque device extending between the second end of the load bearing cable and the payload hook. The anti-torque device permits the payload hook to freely rotate relative to the longitudinal axis of the load bearing cable. The frame assembly is attached to the payload hook and comprises an airframe with a plurality of payload hooks secured thereto. The payload hooks are used for selectively attaching and releasing multiple payloads. A stabilizing wing and a plurality of legs are also attached to the airframe.

  • Patent number: 5499457
    Abstract: A device for measuring the length and weight of an infant. The device includes a tray into which the infant is placed. The tray is located on a scale that is used to determine the infant's weight. A length measuring device is located adjacent the tray and includes a wand that extends into the tray and moves slidably along the length of the tray. An infant is placed within the tray so that the head of the infant is adjacent one end of the tray. The wand then slidably moves toward the infant until it contacts the sole of the infant's foot at which time a length measurement is taken. The length measuring device includes a breakaway switch and a rocker switch that stops the movement of the wand if it contacts the infant or another obstruction.
