Abstract: Embodiments of the present disclosure provide for improved determination of adjustment unit allocation(s). For a particular user profile and electronic item representation, embodiments determine a recommended adjustment unit allocation particular to a transaction for that user profile and particular electronic item representation that increases and/or maximizes a particular goal metric while simultaneously maintaining or minimizing the decreased likelihood for a user to initiate such a transaction, or maximizing the likelihood that the user will initiate such a transaction. Embodiments of the present disclosure utilize allocation models specially configured for each user and prospective transaction for a particular electronic item representation.

Abstract: An armrest extension device for a wheeled chair includes a tube that has a first end and a second end. The first end and the second end are open. The tube has a first side that is open from the second end to proximate to the first end. A handle is coupled to and extends linearly from the first end the tube. A first cutout is positioned in a bottom of the tube proximate to the first end. The first cutout is substantially complementary to a diameter of a frame member that supports an armrest of a wheeled chair. The tube is configured to laterally insert the armrest into the first side, coincident with insertion of the frame member into the first cutout, to couple the tube to the armrest. The handle is configured to be grasped in a hand of a user.
