  • Publication number: 20250325239
    Abstract: A shift compliance management system manages user compliance with recommendations for shift weight exercises to mitigate risk of a wheelchair user developing pressure ulcers. A sensing device includes an array of pressure sensors to sense the user's weight distribution and to detect timing and duration of weight shifts performed by the user. The sensing device communicates with a user application that assesses a compliance level of the sensed weight shifts with a set of weight shift recommendations for the patient. A compliance server collects patient data and may perform various analytics related to compliance. The analytical data may be presented to the wheelchair user and/or a caretaker to indicate compliance adherence.

  • Publication number: 20150324483
    Abstract: Techniques are provided for determining which entities, in a population of entities, is most like a given entity. In the context of companies, the techniques involve constructing a peer network graph based on company-to-company relationship data. Once the graph is constructed, the weights of the edges are determined, and values for the paths are determined based on the edge weights. Peer connection scores are generated for a particular company based on the number and values of the paths between the node that represents the company and the nodes that represent other companies. Based on the peer connection scores between the particular company and other companies, a subset of the other companies are selected as members of a peer group for the company.

  • Publication number: 20080003722
    Abstract: A method of fabricating a memory card. The method comprises the initial step of providing a leadframe which has a dambar and a plurality of contacts, each of the contacts being attached to the dambar by at least one tie bar. A molded first body section is formed on the leadframe subsequent to the electrical connection of a semiconductor die thereto such that portions of the leadframe other than for the contacts thereof are covered by the first body section. After the tie bars and dambar have been removed from the leadframe, a second body section is formed on the contacts of the leadframe such that portions of the contacts are exposed in a common exterior surface of the second body section. The second body section defines the leading edge of the memory card which has no metal of the leadframe exposed therein.
