Abstract: Described herein are methods and systems for updating digital certificates on a computer and testing to confirm that the update was performed correctly. The testing may involve confirming that a server's common name (CN) and/or a server's subject alternative name (SAN) matches the domain name server (DNS) name utilized to access the server, confirming that, for all the certificates sent in chain, each certificate's expiration date is less than or equal to the expiration date of that certificate's parent certificate, confirming that the certificates' authority key identifier (AKI), subject key identifier (SKI), and/or authority information access (AIA) are in compliance, and comparing available cipher suites to a list of pre-approved cipher suites.

Abstract: A bone plate system is provided. The system includes two or more fastener locks stacked on top of each other and located between two holes in a plate adapted to receive bone fasteners. An actuator is provided between the locks. As the actuator is advanced, the locks are moved sequentially into position, firstly, to prevent one or more bone fasteners from backing out of the plate while permitting the fasteners to angulate and, secondly, to lock the angulation of the bone fasteners while still providing back out protection in situ. An expandable bone plate having a top plate interconnected to a bottom plate by a rack and pinion is provided. The rotation of the pinion with a driver lengthens or shortens the plate incrementally for custom length adjustment. The length is fixed in position with the simple removal of the driver and no further step is required to lock the plate length.

Abstract: There is disclosed a MicroFlex Scope (MFS). The MFS is a dexterous endoscope providing access, direct visualization, tissue sampling, and treatment, of body lumens. In one embodiment, the distal end of the MFS is an ultra-flexible tip that comprises a plurality of thin, curved shape memory alloy (SMA) actuator elements attached to at least one structural skeleton, a coil spring skeleton or hinge structure. The SMA actuator elements in each structural skeleton segment are indirectly heated by a heater element and produce force in response to their temperature relative to specific thresholds. In configurations comprising a plurality of actuator elements, multiplexing/demultiplexing of heating currents and sensor voltages may be accomplished via a parallel bus and demultiplexing circuit. In this regard, a demultiplexing circuit using standard microelectronic fabrication techniques may be designed to achieve individual sensing and control over each actuator element.

Abstract: A method of producing a smoother torque from a multi-pole motor is described. The method includes determining an angular position of a rotor of the multi-pole motor, and producing a current to drive the multi-pole motor. The current is controlled based on the angular position of the rotor so as to produce a smoother torque, without the substantially sinusoidal characteristics of torque produced by a steady current. An apparatus is described which can employ methods of the invention to provide smoother torque from a multi-pole motor.
