Abstract: The present disclosure combines Software Defined Networks (SDN) concepts with Security concepts. The coordination between SDN and Security provides a myriad of advantageous use cases. One exemplary use case involves providing a fast path at network speeds using SDN by routing network traffic to bypass a security appliance once the security appliance determines that the security appliance no longer needs to inspect the network traffic. Another exemplary use case involves remote provisioning of security zones.

Abstract: A system for controlling solid state lighting including a source to supply any one of a range of AC or DC voltages to a plurality of light strings. The source includes a power factor correction circuit 14 for controlling the power factor to the system and a separate transformer for each light string. The current can pass through each LED string is independently limited by each corresponding LED driver circuit. The current through each LED string can be modified according to a feedback monitor system that measures parameters such as LED characteristics, forward current, temperature, and LED output intensity/color. Each LED string has an independent sensor that monitors the voltage across each switching device in the corresponding LED driver circuits and utilizes a control unit to control the voltages supplied by each corresponding transformer through control signals in response to the monitored switching device voltages.

Abstract: An improved method and system for removing time-varying Doppler shifts and the effects of turbulence from data comprising at least one processor operating to estimate the average instantaneous frequency; reduce or remove noise from the state space variables estimates describing the frequency of the target; compensate for the motion of the target to obtain motion compensated data and increase the coherency of the data, and reduce or remove the noise from the state space variables describing the frequency of the target using a filter or smoother. Alternately, the method and system may comprise at least one processor operating to estimate the average instantaneous frequency of the first harmonic of a moving target; the average instantaneous frequency being inputted into an error reduction subroutine; using state space estimates of the frequency, calculating a time warping to remove the effect of the Doppler shift; and focusing the data using a modified PGA.

Abstract: A power control system for an illumination system has a power source to supply any one of a range of AC or DC voltages, a power conversion stage, one or more light emitting device(s) for illumination and/or wireless communication, a controller controlling an output stage to receive and send information to regulate the power and/or current to the light emitting device(s), and a programmable voltage clamping or linear regulator arrangement contained within the output stage that can be controlled to increase a dynamic dimming ratio of current and/or power through the light emitting device(s) and to enable power or current modulation for wireless optical communication of light emitting device(s). The power control system enables current and power to be provided to one or more attached light emitting device(s) with a vastly extended dynamic dimming range such that different light emitting devices can be powered using the same driver output stage(s).

Abstract: An electrically powered lock, e.g. an electric strike, includes a housing and a latch mounted with respect to the housing so as to be pivotable about a latch axis between an open position and a locking position. The latch has a latch face and a segment that projects laterally of both the latch axis and the latch face. A locking element is mounted for rotation about a lock axis normal to but offset from the latch axis for selectively blocking the laterally projecting segment to hold the latch in the locking position or allowing the latch to move to the open position to thereby place the lock respectively in a locked condition or an unlocked condition. An electrically powered driver is disposed within the housing laterally of the latch axis actuable in a direction generally parallel to the latch axis for effecting rotation of the locking element.

Abstract: Disclosed are new approaches for scheduling workers at remote locations. Work assignments may be organized into shifts associated with one or more workers and one or more recipients. Tasks are associated with the shift and have an updatable status. Shifts may be replicated by cutting and pasting or by specifying a recurrence definition. The tasks associated with a shift may then be replicated. The status of tasks may be updated using a voice telephony system. The status of tasks may also be reported from a computer located on the recipient premise. Text and/or voice comments and the task status may be accessible by managers, clients, and concerned parties from a web portal accessible using a computing device, such as a tablet computer. Methods for automatically associating providers with shifts and adding tasks to shifts are also disclosed.

Abstract: Systems and methods are disclosed for improving healthcare outcomes, such as following discharge of a patient following discharge from a hospital or other facility. In some embodiments, a first computer system of a first entity, detects discharge of a patient from a second entity based on activities of the patient and in response transmits, to an electronic device of a second entity, a request for discharge information of the patient. One or more follow-up activities are automatically scheduled for the patient and participation of the patient in the activities is verified by the first computer system. Follow-up activities may include a visit to a primary care physician (PCP), an in-person phone call, automated phone call, and other activities. One or more escalation actions may be taken based on results of these activities or failure of the patient to take part in these activities.

Abstract: User names and user groups serve as the basis of a formal policy in a network. A passive monitor examines network traffic in near real time and indicates: which network traffic is flowing on the network as before; which users or user groups were logged into workstations initiating this network traffic; and which of this traffic conforms to the formal policy definition. In one embodiment of the invention, users and user groups are determined by querying Microsoft® Active Directory and Microsoft® Windows servers, to determine who is logged onto the Microsoft® network. Other sources of identity information are also possible.
