  • Patent number: 11887709
    Abstract: Systems and methods predict functional and cognitive recovery of a person after the person has experienced a brain injury such as traumatic brain injury, cerebrovascular disease, and stroke. A computer system includes a database that stores multimodal data of the person recovering from a brain injury and a computer that analyzes the multimodal data over multiple intervals that span several months of time. The computer executes longitudinal heterogeneous trajectory analysis on the multimodal data and executes separation of heterogeneous groups that include good recovery potential of the brain injury, moderate recovery potential of the brain injury, and poor recovery potential of the brain injury. Based on the longitudinal heterogeneous trajectory analysis and the separation of the heterogeneous groups, the computer predicts functional recovery of the person from the brain injury.

  • Patent number: 10246254
    Abstract: A collapsible waste receptacle is disclosed with front and rear frame pieces generally defining an exterior boundary. The waste receptacle is configured to move between an expanded and a collapsed configuration. In the expanded configuration, a bottom frame piece may be attached to both the front frame piece and the rear frame piece to define at least a lower portion of the exterior boundary of the receptacle, and a top surface may contact the front frame piece and the rear frame piece. To transition to the collapsed configuration, the bottom frame piece may disconnect and rotate to generally vertical orientation within the exterior boundary of the receptacle. The top surface may rotate around a frame piece to generally vertical orientation outside the exterior boundary. The front and rear frame pieces may move towards each other to define a collapsed configuration, e.g. assisted by the inward folding of remaining side panels.

  • Patent number: 9049956
    Abstract: A cart suitable for supporting a grill, including a grill bowl. The cart has two union members with curved channels for receiving tubular, U-shaped frame members. The union members may be in the form of two similar (but not necessarily identical) halves joined together to enclose the frame members. The tubular channels of the union members resist movement (such as twisting and tilting) in at least two directions. The union members lock the frame members in place with internal protrusions that fit into mating depressions or holes in the frame members. Extra rigidity is added to the cart by one or more side tables which are structural members as well as functional tables. The side tables thus serve as cross-members between two frame assemblies. The grill's lid can easily be tilted back to rest in place on lid supports underneath the bottom edge and contact points on the side tables.

  • Patent number: 8316836
    Abstract: Two main embodiments of a heat shield for a barbecue grill are disclosed herein. Both are designed to reduce the transfer of heat from the heated volume of the cooking chamber to the handle of the barbecue grill. The first embodiment mounts to the exterior of the cooking chamber and is disposed between the cooking chamber and the handle. The first embodiment is contoured to interrupt the convective flow of heated air away from the handle. The second embodiment mounts to the interior of the cooking chamber opposite the handle. The second embodiment rests adjacent the inside surface of the cooking chamber to form a partially or substantially closed volume that serves as an insulating barrier for the handle.

  • Patent number: 7968836
    Abstract: Photonic crystal (PC) sensors, and sensor arrays and sensing systems incorporating PC sensors are described which have integrated fluid containment and/or fluid handling structures. The PC sensors are further integrated into a sample handling device such as a microwell plate. Sensors and sensing systems of the present disclosure are capable of high throughput sensing of analytes in fluid samples, bulk refractive index detection, and label-free detection of a range of molecules, including biomolecules and therapeutic candidates. The present disclosure also provides a commercially attractive fabrication platform for making photonic crystal sensors and systems wherein an integrated fluid containment structure and a photonic crystal structure are fabricated in a single molding or imprinting processing step amendable to high throughput processing.
