Abstract: A device may include a fluid region. A device may also include a magnetochemical sensor for detecting magnetic particles in the fluid region, wherein the magnetochemical sensor comprises: a first ferromagnetic layer, a second ferromagnetic layer, and a spacer layer situated between and coupled to the first ferromagnetic layer and the second ferromagnetic layer. A device may further include a current-carrying structure for drawing the magnetic particles in the fluid region toward the magnetochemical sensor, wherein: the current-carrying structure consists of a single, undivided structure, and the current-carrying structure is configured to carry a current in at least one direction that is substantially parallel to an in-plane axis or a longitudinal axis of the magnetochemical sensor. The magnetochemical sensor may be one of a plurality of magnetochemical sensors in a sensor array.

Abstract: The present invention provides a system for retailers to monitor and track customer interaction with a product in a retail environment. The system of the present invention utilizes RFID tagged products and communicating with near field communication in an Internet of Things environment for a more comprehensive relationship between customers and the products of interest. Where the products are not so connected, the system of the present invention alerts the need for same.

Abstract: The present disclosure relates to a quantum system of dimension M comprising a transmon device. The transmon device is in an initial state ?ini which is restricted to a state ?S of a N-dimensional quantum system embedded in the quantum system, where N<M. The transmon device is configured to receive a sequence of pulses for transforming the initial state ?ini to a state ?ext of the quantum system. The transmon device is connected to a readout that is configured to perform a projection-valued measure (PVM) of the transmon device in its state ?ext.

Abstract: An optical module includes an optoelectronic assembly and a heat spreader. The optoelectronic assembly includes a flat, rigid substrate, an array of electrical contacts positioned on a first portion of the substrate, and an optoelectronics assemblage that is electrically connected to the array of contacts and is positioned apart from the array of electrical contacts. The heat spreader is comprised of a thermally conductive material and comprises a second portion that is structurally connected to the first portion and a third portion that is thermally connected to the optoelectronics assemblage.

Abstract: An electronic bartering system and method for facilitating a trade of a first item owned by a first user for a second item owned by a second user when the first user and the second user are connected to a network. The electronic bartering system and method receives a request from the first user, allows the second user to access items owned by the first user, receives a response from the second user, and receives an acceptance from the first user The request identifies the second item and is a potential trade request. The response identifies the first item and is a trade offer The trade comprises the potential trade request, the trade offer, and the acceptance.
