| 20090021557 | Modular encoder - A modular encoder has been developed that can be mounted to a motor shaft without requiring time consuming alignment or special tools. The encoder includes a base having an annular opening, the base including a plurality of resilient arms surrounding the annular opening with each arm having a terminal end that extends into the annular opening, and a hub having a horizontal flange with a top and a bottom surface and a generally vertical wall extending from the bottom surface of the horizontal flange, the wall is configured to fit within the annular opening of the base and is circumscribed with a groove for receiving the terminal ends of the resilient arms to secure the hub to the base and enable rotation of the hub within the annular opening of the base as the terminal ends of the resilient arms slide within the groove. | 01-22-2009 |
| 20100060677 | Drive Belt Slip and Belt Wear Detection - An imaging system for a printer utilizing a friction belt drum drive is comprised of a drum position sensor, drum pulley, drive belt, motor pulley, drive motor, drive motor position sensor, and controller. The velocities of the drum and motor drive pulleys are measured using the controller and position sensors. These velocities along with the drive ratio are used to determine and monitor slip between the belt and pulleys. The magnitude of the slip measured can be used to trigger the controller to respond to the slip event. These responses may include, for example, disabling the motor or reducing motor current or providing a warning indicative of an excessive slip event. Slip measurement combined with other measurements such as motor current can be used to determine the torque capacity of the friction drive. Further, long-term changes in the ratio of pulley velocities can be used to determine drive belt wear. | 03-11-2010 |

| 20080200550 | Inhibition of Hiv-1 Replication by Disruption of the Processing of the Viral Capsid-Spacer Peptide 1 Protein - Inhibition of HIV-1 replication by disrupting the processing of the viral Gag capsid (CA) protein (p24) from the CA-spacer peptide 1 (SP1) protein precursor (p25) is disclosed. Amino acid sequences containing a mutation in the Gag p25 protein, with the mutation resulting in a decrease in the inhibition of processing of p25 to p24 by dimethylsuccinyl betulinic acid or dimethylsuccinyl betulin, polynucleotides encoding such mutated sequences and antibodies that selectively bind such mutated sequences are also included. Methods of inhibiting, inhibitory compounds and methods of discovering inhibitory compounds that target proteolytic processing of the HIV Gag protein are included. In one embodiment, such compounds inhibit the interaction of the HIV protease enzyme with Gag by binding to Gag rather than to the protease enzyme. In another embodiment, viruses or recombinant proteins that contain mutations in the region of the Gag proteolytic cleavage site can be used in screening assays to identify compounds that target proteolytic processing. | 08-21-2008 |
