Abstract: Systems and techniques are provided for a resource transfer system. An instruction to transfer a first quantity of a resource from a first resource pool to a second resource pool may be received. A hold may be placed on a second quantity of the resource in the first resource pool. The held second quantity of the first resource may not be transferred from the first resource pool until the hold is released. Responsive to receiving a message that fulfills a condition on the hold and an instruction to execute the transfer, the hold may be released. A register that is in the first resource pool and is associated with the resource may decremented by the first quantity, and a register that is in the second resource pool and is associated with the resource may be incremented by the first quantity.

Abstract: A sampling system and method are used for extracting a sample of dry product from a receptacle. An extraction tube having a perforated portion is disposed in a product storage volume of the receptacle. A pressurized air source is connected to a first end of the extraction tube. A sample collection device is located outside of the receptacle and serves to separate the sample from an airflow driven by the pressurized air source. An inlet of the sample collection device is connected to a second end of the extraction tube. A sample outlet is adapted to dispense the sample, and an air outlet is provided for venting pressurized air.

Abstract: A blood pressure monitor configured to removably mount to a cuff in a substantially symmetrical position with respect to a width of the cuff can include a housing defining an interior, a first port, and a second port. The first port can: secure to a first prong of the cuff when the cuff is mounted in a first orientation; receive and secure to a second prong of the cuff when the cuff is mounted in a second orientation; and enable fluid communication between the interior and at least one of a first fluid passage within the first prong and a second fluid passage within the second prong. The second port can: secure to the second prong of the cuff when the cuff is mounted in the first orientation; and receive and secure to the first prong of the cuff when the cuff is mounted in the second orientation.
