  • Patent number: 11969353
    Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.

  • Patent number: 11386255
    Abstract: Capturing and processing a digital image of a pictorial (e.g., hand-drawn) representation of a schematic or block diagram as a digital image to aid in creation and maintenance of electrical designs is disclosed. Processing of the digital image includes processing to determine design parameters to create an informational format useful as input to other design software. Design parameters may include schematic layout and attributes such as maximum output voltage, minimum input voltage, ambient temperature, etc. The method and system also include storage of information accessible to refine designs and perform simulations of designs as part of an overall electrical design process. Associated devices and methods are disclosed as well.

  • Patent number: 10835076
    Abstract: An extended life roller grills for re-thermalizing and merchandising food product with easily replaceable bearing assemblies, drive assembly and roller tubes. The grill is comprised of rotation of a plurality of heated internally tubes, a drive assembly that transfers rotational motion to the roller tubes from a cam or chain or gear system or cog belt attached to a motor providing rotational motion and force to the roller tubes. Roller grill chain drive or gear drives, or cog belt or cam drives that utilize replaceable bearing assemblies for extending the service life the roller grill. A cam drive assembly substantially increases the reliability, ease of assembly and disassembly, serviceability, and maintenance of the roller grill. Cam drive provides for easy removal, servicing and replacement of roller tubes not available on other drive systems for roller grills. Replaceable bearing journals to extend the life span of chain, gear, cam or belt drive grills.
