  • Patent number: 12277740
    Abstract: A biometric sensor may include a scanner configured to capture a biometric data and an adjustment mechanism configured to respond to a force applied to the biometric sensor by shifting the biometric sensor from a neutral position to an adjusted position. The adjustment mechanism may be configured to respond to the removal of the force by returning the biometric sensor to the neutral position. While the biometric sensor is in the neutral position, the scanner may be capable of capturing a biometric data of a majority of users interacting with the apparatus. Accordingly, the biometric sensor may be able to operate with minimal adjustments. The biometric sensor may be part of a dispensing cabinet such that the biometric data captured by the biometric sensor may be used to control access to the dispensing cabinet.

  • Patent number: 12278868
    Abstract: A medical device controller operating in conjunction with a medical device determines one or more current versions of executable code associated with one or more processors in a medical device. Medical devices may include infusion pumps, other patient treatment devices as well as vital signs monitors. The medical device controller determines one or more current versions of executable code and configuration information associated with the one or more processors in the medical device. The medical device controller further determines which of the processors in the medical device require updated executable code, and which of the processors in the medical device require updated configuration information. The medical device controller distributes to the medical device as required at least one of the updated executable code and the updated configuration information. The medical device deploys the distributed updates, and activates the updates at a clinically appropriate time.

  • Patent number: 12257419
    Abstract: A medical device such as an infusion system detects that an accessory has been coupled to the device. The medical device initially operates in a first mode of operation. The medical device, in response to the detecting, associates the accessory with a different mode of operation for the medical device that requires changes to at least one of the operating parameters for the infusion system or elements within a graphical user interface. The medical device then automatically changes the mode of operation from the first mode of operation to the associated different mode of operation to reflect the coupling of the accessory to the infusion system.
