Filed:

Oct 23, 2001

Appl. No.:

10/047183

Inventors:

Timothy Allen Pletcher - Eastampton NJ
Pabitra Datta - Cranbury NJ
Christopher Just Poux - Mercerville NJ
Randall Eugene McCoy - McConnellsburg PA

Assignee:

Sarnoff Corporation - Princeton NJ

International Classification:

A61M 1500

US Classification:

12820315, 12820321, 12820322, 12820225

Abstract:

Apparatus and a concomitant method for electrostatically depositing select doses of medicament powder at select locations on a substrate. Specifically, the apparatus contains a charged particle emitter for generating charged particles that charge a predefined region of a substrate and a charge accumulation control circuit for computing the amount of charge accumulated upon the substrate and deactivating the emitter when a selected quantity of charge has accumulated. Additionally, a triboelectric charging apparatus charges the medicament powder and forms a charged medicament cloud proximate the charged region of the substrate. The medicament particles within the medicament cloud electrostatically adhere to the charged region. The quantity of charge accumulated on the substrate at the predefined region and the charge-to-mass ratio of the medicament powder in the cloud control the amount (dose) of medicament deposited and retained by the substrate. Consequently, this apparatus accurately controls both medicament dosage and deposition location.

Abstract:

An optical element such as a rear projection screen for an image display device comprises at least two substantially rigid sheet members each having a first major surface and a second major surface providing a plane of incidence and a plane of emergence, respectively, through which light is transmitted sequentially. A first sheet member comprises a Fresnel lens, and a second sheet member comprises a lenticular lens array on each of the major surfaces thereof. The plane of emergence on the second major surface of the first sheet member includes the Fresnel lens formed of a radiation curable material. A method of making the Fresnel lens is described.
