Abstract: Disclosed herein are methods of producing a gas at a controlled rate, the methods comprising directing air through a layered bed to produce a gas. The layered bed comprises alternating layers of a layer of dry particles comprising a precursor and a layer of dry particles comprising a proton-generating species. The gas is produced at a rate that is controlled by controlling the presence or absence of air flowing though the layered bed, the amount of time the air flows through the layered bed, the total number of layers in the layered bed, the average thickness of each of the layers of dry particles comprising the precursor in the layered bed, the average thickness of each of the layers of dry particles comprising the proton-generating species in the layered bed, the temperature the method is performed at, or a combination thereof.

Abstract: Particular embodiments may enable configuring settings of a vehicle in a designated mode. A signal to perform a vehicle leveling process using an electronically controlled suspension of a vehicle may be received. A roll angle and a pitch angle of the vehicle as parked may be assessed based on data received from a position sensor built into the vehicle. Signals to adjust an electronically controlled suspension of the vehicle to reduce the roll angle or the pitch angle so that the vehicle is level as parked may be sent based on the assessed roll angle and pitch angle exceeding a threshold value. Data may be transmitted to present information related to the vehicle leveling process in a graphical user interface.

Abstract: A device for manipulating many hundreds or thousands of microdroplets into an array using EWOD or oEWOD is provided. The device comprises: i) a chip comprising a first region for receiving and manipulating microdroplets; a second region comprising the array and a plurality of electrowetting pathways leading to the array; ii) a microdroplet source configured to provide microdroplets of a predetermined target diameter; iii) a channel configured to provide fluid communication between the microdroplet source and the first region of the chip; and iv) a pressure source configured to move the microdroplets between the microdroplet source and the first region of the chip. The electrowetting pathways on the chip are centre to centre separated by at least double the predetermined target diameter of the microdroplets from the microdroplet source. Furthermore, the controller is configured to enable synchronous movement of the microdroplets in the electrowetting pathways by application of EWOD or oEWOD force.

Abstract: A method for translating user inputs into discretely functional styled standalone features includes receiving a feature selection associated with a front-end user interface element configured for a client-side application from a user device at a designer-developer application. For each feature of the feature selection, the method identifies a data exchange format of the feature and determines whether the feature selection indicates a change to the feature. When the feature selection indicates the change to the feature, the method maps the change to an appropriate web-development language based on the type of edit associated with the change and updates the data exchange format for the feature of the feature selection based on the change. The method also receives a request for the front-end user interface element and communicating the data exchange format for each feature associated with the front-end user interface element of the request.
