Abstract: In an LDO regulator, two feedback loops are created. The first feedback loop includes a high power PNP bipolar power transistor connected in series between the input voltage Vin terminal and the output voltage Vout terminal. The first feedback loop includes a first error amplifier that controls a drive transistor to drive the base of the power transistor such that Vout matches a set voltage Vset. This first feedback loop circuitry uses an operating voltage (the upper rail voltage) that is regulated by a second feedback loop and is approximately 300 mV greater than Vout. As a result, the control circuitry will be powered by a low ripple supply to improve output PSRR. Further, the power transistor is connected such that any noise in the input voltage is a common mode voltage across the base-emitter of the transistor.

Abstract: A device for quickly advancing/retracting a biopsy tool (or other driven object) into position through a colonoscope or other such scope. The device includes a drive actuator, a transmission for coupling the actuator to a driven object (biopsy tool), an attachment assembly that couples the device to the endoscope, such as to a biopsy port on the endoscope, an electronic control unit, and a user interface. Preferably, the driver/biopsy tool coupling consists of a motor and a combination of gears and friction rollers.

Abstract: A computing system determines incremental values associated with a plurality of clustering solutions. Each of the clustering solutions groups stores of a retailer into clusters in a different way. For each clustering solution in the plurality of clustering solutions, the incremental value associated with the clustering solution indicates a difference between an estimated revenue associated with the clustering solution and revenue associated with a baseline clustering solution. The computing system then determines, based on the incremental values associated with the plurality of clustering solutions, the appropriate number of clusters. The clustering solutions that group the stores into more or fewer clusters than the appropriate number of clusters tend to be associated with incremental values that are the same or lower than the clustering solutions that group the stores into the appropriate number of clusters.

Abstract: Embodiments include active protection systems and methods for an aerial platform. An onboard system includes one or more radar modules, detects aerial vehicles within a threat range of the aerial platform, and determines if any of the plurality of aerial vehicles are an aerial threat. The onboard system also determines an intercept vector to the aerial threat, communicates the intercept vector to an eject vehicle, and causes the eject vehicle to be ejected from the aerial platform to intercept the aerial threat. The eject vehicle includes a rocket motor to accelerate the eject vehicle along an intercept vector, alignment thrusters to rotate a longitudinal axis of the eject vehicle to substantially align with the intercept vector, and divert thrusters to divert the eject vehicle in a direction substantially perpendicular to the intercept vector. The eject vehicle activates at least one of the alignment thrusters responsive to the intercept vector.

Abstract: The present disclosure is directed to a system and method for surgical training with low cost, reusable materials and a highly customizable virtual environment for skill-building. According to various embodiments, a surgical training tool is usable in conjunction with a support structure configured to at least partially constrain the tool movement. Meanwhile, the tool is tracked in real-time with off-tool detectors to generate a tool path driving a virtual rendering of the surgical training tool in an operative environment. The virtual rendering may be visually observable via a display device and may include a customizable and/or selectable operative environment with one or more structures that can be operated on by the virtual surgical training tool. By tracking the virtual tool interaction with the virtual structures, a task path may be established for documenting and/or objectively assessing the performance of one or more operative tasks.

Abstract: Embodiments are directed to determining a risk of encountering malware based on social context, to determining malware threats based on social associations and to ranking antimalware programs according to the program's ability to protect against specific threats. In one scenario, a computer system receives a malware notification associated with a user that identifies a type of malware encountered by the user. The computer system identifies various persons that are part of a social group associated with the user and determines that at least one of the identified persons associated with the user has an increased likelihood of encountering the identified type of malware, based on information derived from identifying the persons that are part of the social group. Optionally, the computer system notifies the identified persons of the increased likelihood of encountering the identified type of malware.

Abstract: Customer data is retrieved that includes customer transactions of a retailer for a first time period and a second time period prior to the first time period. Each customer transaction may be associated with an identified customer. Customer transactions that occurred during the second time period and that are associated with an identified customer that was identified after the second time period are removed from the customer data. For each identified customer, a customer identification weighting factor is determined based on a customer identification likelihood. A total number of customer transactions associated with the identified customer is multiplied by the identification weighting factor to determine a weighted total number of customer transactions for the identified customer. The weighted total number of customer transactions for the identified customer is associated with the identified customer in the customer data. A report including a representation of the customer data is output.
