Abstract: Systems and methods for continuous injection of fluid, in some examples these apparatuses may include a manifold, a pair of reciprocating pistons, and an actuation control that may apply both suction (aspiration) and injection of fluid as part of the same actuation. The systems and methods may be configured to simplify the operation of a continuous fluid injection system, including one that aspirated prior, to injection to confirm the absence/presence of blood.

Abstract: System and method provide wireless distributed lighting control systems implementing a secure peer-to-peer, self-organizing and self-healing mesh network of actuators and system inputs. The system and method can be designed specifically for indoor and outdoor lighting where actuators include in-fixture, on-fixture and circuit control modules with ON/OFF and full range dimming capabilities, and system inputs include occupancy/vacancy sensors, daylight sensors and switches. A unique messaging protocol facilitates wireless and wired communication between actuators and system inputs, and provides web-based commissioning and monitoring of the lighting control system using a wireless access point accessible from a local network or Internet which can provide an intuitive and easy to use Graphical User Interface (GUI).

Abstract: A top brush interrupt system for a vehicle wash system particularly adapted for pickup trucks that includes a top brush rotatable on a generally horizontal cross shaft that journalled in a pair of spaced arms that are pivoted on a frame for movement toward and away from the top of the vehicle to be washed. The interrupt system includes a proximity switch on the frame cooperating with a proximity target on one of the arms for sensing when the top brush is in position on top of the vehicle and for indicating when the top brush is not on the top of the vehicle and associated circuitry including timing means for terminating rotation of the top brush and/or raising the top brush from the vehicle.

Abstract: Automatic vehicle washer. The washer includes a vehicle washing apparatus, source of electrical power, manual input, code verifier and activator. The manual input allows a driver of a vehicle to transmit a numerical signal to the code verifier. If the code verifier determines that the numerical signal corresponds to a predetermined numerical code, the energizer interconnects the vehicle washing apparatus with the source of electrical power.
