Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 205

US Classification:

347 63

Abstract:

A fluid-jet printhead has a substrate having at least one layer defining a fluid chamber for ejecting fluid. The printhead also includes a resistive layer disposed between the fluid chamber and the substrate wherein the fluid chamber has a smooth planer surface between the fluid chamber and the substrate. The printhead has a conductive layer disposed between the resistive layer and the substrate wherein the conductive layer and the resistive layer are in direct parallel contact. The conductive layer forms at least one void creating a planar resistor in the resistive layer. The planar resistor is aligned with the fluid chamber.

H01L 21/00
G01J 1/44

US Classification:

136246, 438 69, 250206, 257E21001

Abstract:

A solar radiation collection system includes a first photovoltaic cell, a second photovoltaic cell, and an optical medium, the optical medium. The optical medium has a first zone configured to transmit radiation incident on the first zone to the first cell, a second zone disposed adjacent a side of the first zone, and a first dichroic surface configured to reflect a first portion of radiation incident on the second zone such that the reflected radiation is directed toward the first cell by internal reflection and to transmit a second portion of radiation incident on the second zone to the second cell.

International Classification:

B32B 1/00
B29C 65/52

US Classification:

428174, 156196

Abstract:

Apparatus and methods are provided. A first sheet of flexible material is placed against a surface of a form. The first sheet bears an adhesive on one side. A second sheet of flexible material is brought into contact with the adhesive and the two sheets are pressed into conformant contact with the surface of the form. The first and second sheets are thus bonded to form a rigid or semi-rigid entity having a cross-sectional shape in accordance with the surface contours of the form.

US Classification:

136246, 359853, 362297, 29428

Abstract:

Apparatus and methods are provided for use with photovoltaic cells, light emitting devices and the like. Reflective regions are formed on a sheet of flexible, non-metallic sheet material. The sheet material is folded to at least partially define a finished shape. Supports complete and maintain the folded condition such that one or more truncated parabolic troughs are defined. Incident light may be received and concentrated, or emitted light concentrated and projected, by way of the troughs.
