Abstract: Disclosed herein are methods and systems for detection and discrimination of optical signals from a densely packed substrate. These have broad applications for biomolecule detection near or below the diffraction limit of optical systems, including in improving the efficiency and accuracy of polynucleotide sequencing applications.

Abstract: A receptacle system includes a front wall, a first side wall coupled with the front wall, a rear wall coupled with the first side wall, a second side wall coupled with the front wall and a bottom coupled with each of the front, first side, rear and second side walls. A first notch extends into a top edge of the first side wall. A second notch extends into the top edge of the second side wall and through the second side wall. The first and second notches are aligned parallel with the front wall, the rear wall or both. A top includes a front edge pivotably coupled with the top edge of the front wall and a rear edge configured to meet with and partially extend into the first and second notches. A through-hole is provided in the first side wall, the second side wall or both.

Abstract: A computer-readable storage medium storing instructions executable by a processor for resolving permissions using role activation operators to evaluate permissions assigned to a user in a role context inheritance hierarchy. The stored instructions comprise several steps: a step of retrieving a plurality of activated roles within a role context that match roles assigned to a user, wherein one or more permissions in the role context inherit from one or more permissions in a parent role context in a role context permission inheritance hierarchy; a step of determining an aggregate permission for each of the plurality of activated roles, wherein a role activation operator determines how an activated role is evaluated; a step of processing the aggregate permissions for the plurality of activated roles; and a step of resolving a final permission for the user.

Abstract: A system and method for creating an editable service metadata asset lifecycle event notification distribution list in a service metadata repository. The system provides the capability for a distribution list owner to create a distribution list of one or more distribution recipients. A sender can send a service metadata asset lifecycle event notification to the distribution list owner, and the members of the distribution list will also receive the service metadata asset lifecycle event notification. The system further provides the capability for the sender to edit the distribution list, prior to sending the message to the distribution list owner and the members of the distribution list.

Abstract: A current sampling half-bridge output driver capable of driving a wide range of loads using an accurate selection of current sensing resistors. Pluralities of stages are connected in series with the current sensing resistors from each stage connected in series. A range selector selects the stage appropriate for each current load. The reference resistors for a selected stage includes the current sensing resistor associated with that stage added in series to all current sensing resistors electrically connected between the selected stage and the load. The disclosed circuit avoids switching resistors in and out of the circuit and thereby increases the accuracy of the sensing resistor circuit.

Abstract: A system and method for connectionless sensing of the physical parameters of a shaft that is capable of continuous rotation. The system involving placing a circuit assembly on the rotating shaft, powering the circuit assembly through energy transferred from a stator coil across a gap to a rotor coil, sensing physical parameter data on the shaft and communicating this data across the gap from the rotor coil to a stator coil.

Abstract: A protection circuit for a semiconductor device such as a field effect transistor is disclosed having an oscillator which is connected to both the gate turn on circuitry and to the drain-source circuit of the field effect transistor for sensing the voltage of the drain-source circuit and for turning off cyclically the field effect transistor upon the simultaneous occurrence of a gate turn on signal to the gate of the transistor and high drain-source voltage.
