A battery powered fluid sprayer includes a shelter that the battery is mounted in to provide power to the electric components of the sprayer. The shelter protects the battery from falling fluid droplets. The shelter extends above the battery and projects outward laterally and longitudinally to protect the battery. The battery can move vertically downward to dismount from the fluid sprayer.

A water spray wand comprises an internal water pipe, a spray handle, a compartment for a battery and a light. The spray handle is configured such that when the flow of water is permitted through the spray wand, the electronic communication between the battery compartment and the light is completed, and when the flow of water through the spray wand is interrupted, a timer is activated to interrupt the electronic communication between the battery compartment after a predetermined delay.

Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes a low temperatures that do not deform the device. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.

A holographic projection system and method are implemented by a projection device provided on the vehicle; a water mist generating device for generating water mist provided on the vehicle; and a controller in communication with the projection device and the water mist generating device. The controller is configured to detect a signal of user proximity to the vehicle, and activate the water mist generating device and the projection device respectively based on the detected signal, so that the projection device projects an image onto the water mist.
