US Patent:

20080290588, Nov 27, 2008
Filed:

May 24, 2007
Appl. No.:

11/805810
Inventors:

Tim M. Hoberock - Vancouver WA, US
David F.D. Buck - Ridgefield WA, US
Samrin Sing - Portland OR, US
International Classification:

B65H 3/52
US Classification:

271121
Abstract:

An apparatus in an example comprises a sheet holder, a separator surface, a feed head, and one or more arms. The sheet holder supports one or more sheets of media. The separator surface receives a leading edge of a sheet of the one or more sheets of media. The feed head is selectively positionable against a face of the sheet. The one or more arms extend toward an intermediate location of the separator surface to constrain the sheet from movement away from the separator surface.

US Patent:

20100052246, Mar 4, 2010
Filed:

Aug 26, 2008
Appl. No.:

12/198279
Inventors:

Samrin Sing - Vancouver WA, US
International Classification:

B65H 1/00
US Classification:

271171
Abstract:

A media size sensing system includes independently moveable length and width edge guides, in a media tray, for positioning against orthogonal edges of media sheets. A linearly sliding sensor device is provided, and a single linkage connects the length and width edge guides to the sensor device, the single linkage providing a unique position indication that is a function of both length and width for a range of media sheet sizes.

International Classification:

B29C 64/35
B29C 64/153
B29C 64/386
B33Y 40/00
B33Y 50/00
Abstract:

In example implementations, a powder level sensor is provided. The powder level sensor includes a capacitive sensor, a processor, and a cleaning mechanism. The processor is communicatively coupled to the capacitive sensor. The processor interprets a measurement of the capacitive sensor to detect a layer of residual build material on a surface of the powder level sensor. The cleaning mechanism may be communicatively coupled to the processor. The processor activates the cleaning mechanism to remove the layer of residual build material on the surface of the powder level sensor.
