Abstract:
In color printing with a color registration system for the registration of plural color images on an image bearing surface, such as a photoreceptor belt of a color printer, chevron shaped registration marks are imaged on the image bearing surface, which registration marks correspond to the color images and are sensed by a registration marks sensor as the image bearing surface moves in its process direction. The registration marks sensor has chevron shaped optical sensing areas provided by a matching pair of spaced apart elongated bi-cell detectors in a generally chevron shaped pattern. Each of these spaced apart elongated bi-cell detectors has a parallelogram shaped optical sensing area. That parallelogram shaped sensing area is defined by elongated parallelogram sides extending at the same angle as one leg of the chevron shaped registration marks, and parallelogram ends which are parallel to the process direction, so as to provide higher color registration accuracy.

Abstract:
A sheet curl measurement system and method and an automatic sheet decurling system controlled thereby for the printed paper sheets output of printer. The sheet curl may be remotely sensed without contacting or interfering with the motion of the sheets in their normal sheet path, using a simple but accurate optical sheet curl sensor operating on a portion of the moving sheet at an angle thereto and perpendicularly thereto, with displacement insensitive optics, in both an angular direction substantially parallel to the sheet movement direction and an angular direction substantially transverse to the sheet movement direction, with ratioing of the two output signals.

Abstract:
An electrostatic type voltmeter for measuring the potential on a surface, the voltmeter including a probe; a support for supporting the probe in spaced relationship with the surface, the probe having a plurality of spacing element sites thereon for measuring a distance between each of the plurality of spacing element sites and a corresponding area on the surface opposite of each of the plurality of spacing element sites; a plurality of electrostatic element sites, intermixed and adjacent to the plurality of spacing element sites on the probe, for measuring a voltage between each of the plurality of spacing element sites and an area on the surface adjacent to the corresponding area opposite of each of the plurality of spacing element sites. A processor for compensating an output signal of the probe in response to the measurements received from the plurality of spacing element sites and the plurality of electrostatic element sites.
An apparatus such as a connector or circuit includes a substrate having a plurality of conductive members and a plurality of non-conductive members. The conductive members include a plurality of conductive fibers in association with a polymer material. The conductive members and the non-conductive members are disposed in the substrate member and are selectively situated with respect to each other forming a modular matrix configuration of contacts suitable for an array or association with other circuitry.

International Classification:
H01R 12/00 H05K 1/00
US Classification:
439 65
Abstract:
According to various embodiments, exemplary interconnects and methods for interconnection are provided that can include contacts formed by fiber bundles. The exemplary interconnects can be used to form separable or non-separable electro-mechanical connections between one or more of the generally accepted six levels of interconnection. In various embodiments, the exemplary interconnects can allow management of the thermal properties of the electronic devices. Exemplary interconnects can also provided reduced thickness allowing redundancy and additional compliance as desired.

International Classification:
G03G 15/00
US Classification:
399 90
Abstract:
An interconnect includes a first contact portion including carbon fibers, a second portion including carbon fibers, and a member. The first contact portion is capable of electrically biasing the member and the second portion is capable of sensing an electrical bias of the member. Both portions may provide other electrical functions. Both portions may structurally support the member.
