Abstract: A plasmon resonance system, instrument, cartridge, and methods for analysis of analytes is disclosed. A PR system is provided that may include a DMF-LSPR cartridge that may support both digital microfluidic (DMF) capability and localized surface plasmon resonance (LSPR) capability for analysis of analytes. In some examples, the DMF portion of the DMF-LSPR cartridge may include an electrode arrangement for performing droplet operations, whereas the LSPR portion of the DMF-LSPR cartridge may include an LSPR sensor. In other examples, the LSPR portion of the DMF-LSPR cartridge may include an in-line reference channel, wherein the in-line reference channel may be a fluid channel including at least one functionalized LSPR sensor (or sample spot) and at least one non-functionalized LSPR sensor (or reference spot). Additionally, methods of using the PR system for analysis of analytes are provided.

Abstract: A method performed by a computing device of presenting an application menu on a touchscreen includes (a) receiving a signal from the touchscreen indicating that a user has touched an MAE displayed on a screen of the application, (b) in response to receiving, displaying the menu on the touchscreen, (c) receiving a signal from the touchscreen indicating that the user is sliding a cursor across the touchscreen in a first direction and, in response, moving a display position of a slider element of the menu correspondingly on the touchscreen, (d) receiving a signal from the touchscreen indicating that the user has slid the cursor in a second direction substantially orthogonal to the first direction past a selection threshold and, in response, selecting a menu item corresponding to a current location of the cursor, and (e) in response to selecting the menu item, performing an action corresponding to the menu item.

Abstract: A method for collision avoidance includes receiving a maneuver command, obtaining observations from one or more sensors, generating one or more constraints based on the observations, combining the maneuver command and the one or more constraints to generate a constrained maneuver command that deviates from the maneuver command for collision avoidance, sending the constrained maneuver command to a controller. The method can include modifying motion of a vehicle based on the constrained maneuver command to maneuver with collision avoidance.

Abstract: A circuit (26) performs a discrete Walsh transform using a reduced set of arithmetic operators. The circuit (26) comprises a first memory component (32), an adder (36), a subtractor (38), a second memory component (40), and a controller (52). In each of a plurality of stages, the controller (52) enables the first memory component (32) to communicate each of a plurality of pairs of values stored therein to the adder (36) and to the subtractor (38). The controller (52) enables the second memory component (40) to store each of a plurality of results from the adder (36) and the subtractor (38) and to communicate the stored results to the first memory component (32) for use in a subsequent stage.
