  • Publication number: 20240134107
    Abstract: A light source device includes a light guide plate, an optical adhesive, and a light source element. The light guide plate includes a light guide substrate and an enhancement layer. The light guide substrate has a light incident surface, a first surface, and a second surface. The first surface is opposite to the second surface, and the light incident surface extends between the first surface and the second surface. The enhancement layer is disposed on the light guide substrate. A thickness of the enhancement layer is from 1 micrometer to 25 micrometers and a first refractive index of the light guide substrate is greater than a second refractive index of the enhancement layer. The optical adhesive is interposed between the first surface of the light guide substrate and the optical adhesive. The light source element is disposed beside the light incident surface to emit light toward the light incident surface.

  • Patent number: 9692897
    Abstract: Embodiments are directed to routing customer calls to preferred agents. Embodiments receive a call from a customer using a user device; determine an identity of the customer; retrieve information associated with the matching entry; based at least in part on the retrieved information, select one or more agents; and route the call to one of the selected agents. Some embodiments determine a telephone number from which the call was received; comparing the telephone number with a plurality of entries in a customer information database; and determining that the telephone number matches an entry in the database. Other embodiments receive a communication from the user device indicating that the customer has placed the call; determine that the customer is currently authenticated through an online banking session or a mobile application on the user device; and receive a communication from the user device indicating the customer's identity.
