20140340680 | APPARATUS AND METHOD FOR MOBILE DEVICE CAMERA TESTING - A mobile device testing system with a sphere assembly is disclosed. The sphere assembly is a source integrating sphere and a test integrating sphere connected by an optical channel. A source illuminates the source integrating sphere with electromagnetic radiation of a known spectrum of wavelengths, usually light. The electromagnetic radiation travels to the test integration sphere through the optical channel. A first filter assembly and/or a second filter assembly rotate a plurality of filters into the optical channel to change the spectral distribution of wavelengths of the electromagnetic radiation in the test integrating sphere. A mobile device is mounted to the test integrating sphere and the spectral distribution of an image acquired by the mobile device is compared to a spectral measurement from a spectrometer. | 11-20-2014 |

20090033581 | REMOVABLE MEDIA SPINDLE AND ANTENNA ASSEMBLY FOR PRINTER - A removable spindle for use in a thermal transfer printer houses dual RFID reader antennas that are used to read an RFID tag attached to the core of the print media. The information provided by the RFID tag enables the printer to self-calibrate based on the type of media loaded. The antenna design eliminates “null” areas at which the tag cannot be read, and enables the tag to be read around and across the entire length of the printer spindle. The design also allows the media holder to be easily removed from the printer. | 02-05-2009 |

20120259107 | Coupling Low-Molecular Substances To A Modified Polysaccharide - The invention relates to a method for coupling low-molecular substances to a starch-derived modified polysaccharide. The binding interaction between the modified polysaccharide and the low-molecular substance is based on a covalent bond which is the result of a coupling reaction between the terminal aldehyde group or a functional group of the modified polysaccharide molecule resulting from the chemical reaction of this aldehyde group and a functional group of the low-molecular substance which reacts with this aldehyde group or with the resulting functional group of the polysaccharide molecule. The bond directly resulting from the coupling reaction can be optionally modified by a further reaction to the aforementioned covalent bond. The invention further relates to pharmaceutical compositions that comprise conjugates formed in this coupling process and to the use of said conjugates and compositions for the prophylaxis or therapy of the human or animal body. | 10-11-2012 |
