  • Patent number: 10366558
    Abstract: A cash box (18) is provided along with a device (12) for handling notes of value, in which such a cash box (18) is receivable. The cash box (18) has a receiving area (30) for receiving a value note stack and a housing (32) with at least one mechanical coding unit (50) for optional assignment of the cash box (18) to first or second receiving compartments (16) of the device (12). The coding unit (50) has a coding element (60) that is adjustable between first and second positions. The coding element (60) is designed so that the cash box (18) is feedable only to the first receiving compartment (16) when the coding element (60) is in the first position, and only to the second receiving compartment (16) when the coding element (60) is in the second position.

  • Patent number: 10357369
    Abstract: The present application discloses a method of producing a knee replacement implant, an implant for knee replacement formed by using the method, and a knee replacement implant. The method includes: defining a hip center, a knee center, an ankle center and a posterior femoral condylar axis of a lower limb; generating femoral geometric parameters and tibial geometric parameters, the femoral geometric parameters and the tibial geometric parameters being measured in relation to the hip center, the knee center, the ankle center and the posterior femoral condylar axis; collecting anthropometric data from a defined population using the femoral geometric parameters and the tibial geometric parameters; and creating a femoral component and/or a tibial component using the collected anthropometric data.

  • Patent number: 9938688
    Abstract: An excavation system is disclosed for use with a mobile machine having a work tool. The excavation system may have a speed sensor configured to generate a first signal indicative of a travel speed of the mobile machine, and at least one load sensor configured to generate a second signal indicative of loading of the work tool. The excavation system may also have a controller configured to record values of the first signal during travel of the mobile machine toward a material, and to detect engagement of the work tool with the material based on the second signal. After engagement of the work tool with the material is detected, the controller may be further configured to determine an edge location of the material passed through by the work tool based on values of the first signal recorded prior to engagement detection of the work tool with the material.

  • Patent number: 9903100
    Abstract: An excavation system is disclosed as having first and second actuators configured to move a work tool in first and second directions. The second actuator may only be capable of full-range movement when the first actuator is positioned within a sub-range. The excavation system may also have first and second sensors configured to generate first and second signals indicative of first and second actuator movements, and a controller in communication with the first and second sensors. The controller may be configured to command movement of the first actuator to the sub-range, to confirm that the first actuator has moved to the sub-range based on the first signal, to command movement of the second actuator to an end-of-stroke position after the first actuator is confirmed to be within the sub-range, and to selectively record a current position of the second actuator as the end-of-stroke position based on the second signal.

  • Patent number: 9850639
    Abstract: An excavation system is disclosed for a machine having a work tool. The excavation system may have at least one sensor to generate a signal indicative of a load exerted on the work tool. The excavation system may also have a lift actuator and a tilt actuator. The excavation system may also have a controller configured to detect engagement of the work tool with a material pile based the signal. The controller may operate the work tool to load the work tool with an amount of material. The controller may determine whether loading of the work tool has been completed. The controller may lift the work tool when the loading has been completed. The controller may also operate the tilt actuator to shake the work tool. Additionally, the controller may cause the machine to withdraw from the material pile after shaking the work tool.

  • Publication number: 20170327865
    Abstract: The claimed invention provides personalized glucose and insulin information to a user in need thereof. Non-invasive body fluid capture techniques utilize saliva to provide body levels of glucose and insulin as well as optional pharmaceutical ingestion coordinated over time. Saliva captured on cellulose strips are analyzed in real time using oxidation and aptamer conjugate hybridization together with traditional analytical chemistry techniques including liquid chromatography/mass spectrometry (LC/MS) and coordinated against time of pharmaceutical administration. By embracing the P4 (Participatory, Personalized, Predictive, and Preventive) health management method the patient can determine glucose and insulin related wellness levels and if a pharmaceutical is having the correct and desired effect for maximum therapeutic benefit.
