Abstract: The present disclosure describes a system, method, and non-transitory computer readable medium for provisioning multiple instances of a secure communication application on multiple devices. A secure communication application on a first device generates a first set of private keys that are associated with the user and a second set of keys that are associated with the secure communication application executing on the first device. The first set of private keys establishes a set of root identifying keys for the user that are identical for all installations of the secure communication application, while the second set of keys will vary from device to device. In this regard, the first set of root identifying keys must be securely transferred from the first device to any subsequent installations of the secure communication application on one or more second devices.

Abstract: A variety of techniques for performing identity verification are disclosed. As one example, a verification request is received from a remote user. The verification request pertains to a cryptographic key. In response to receiving a confirmation from a local user of the local device, a verification process is initiated. A result of the verification process is transmitted to the remote user. As a second example, a verification request can be received at the local device, from a local user of the device. A verification process with respect to the local user is initiated, and a result of the verification process is transmitted to a remote user that is different from the local user.

Abstract: An automatic tactical light bar includes a body having a plurality of illuminated sides including at least a first illuminated side and a second illuminated side arranged around a central chamber; a plurality of illumination elements fixed to the illuminated sides with at least one illumination element per illuminated side; an electric circuit in communication with the illumination elements and the central chamber, the circuit including at least one orientation sensor; an electric power source in the central chamber and in communication with the plurality of illumination elements through the electric circuit, wherein the at least one orientation sensor controls one of plurality of illumination elements according to the electric circuit, wherein each of the at least one orientation sensors are arranged inside the body to selectively supply power to the at least one illumination elements corresponding to the first illuminated side.

Abstract: A rotationally symmetric surgical instrument for use with a computer aided surgery system which is adapted so that it is easy to check its calibration and methods of checking the calibration of such instruments are described. The instrument includes a body having a working end which includes a working point which characterises the location in space of the working end. The instrument also has a location at which a marker can be attached to the instrument. Only a single formation is located toward the working end which provides a calibration reference point for engaging with a trackable instrument. The single formation has a fixed position relative to the working point. The position of the calibration reference point relative to the marker array can be determined so as to check whether the calibration of the instrument is still accurate.

Abstract: An audio visual homing marker includes a shock-resistant housing with a power supply, audio speaker and LED array inside the housing. A power switch is attached to the housing and the power supply. The housing includes a plurality of bulkheads that create a plurality of chambers. The power supply, the audio speaker and the LED array are each contained within separate chambers. The power switch is biased to the on position. The housing is a generally cylindrical polycarbonate structure and may be a transparent material. The LED array may include a plurality of LEDs attached around the perimeter of the housing. The audio speaker can be a siren or other loud speaker. The LED array may emit a visible or non-visible light. A variety of holders and dispensers make it easy to deploy the markers from a car or aircraft.

Abstract: The present invention is directed to a contact center, comprising: (a) a plurality of media servers 112a-n, each of the media servers being associated with a plurality of corresponding agent communication devices 120a-i positioned in a respective agent domain 100a-n; (b) a plurality of gateways 128a-n, each of which is currently controlled by a corresponding one of the plurality of media servers 112a-n and positioned in a contactor domain 104; and (c) a packet-switched Wide Area Network (WAN) 108 connecting the plurality of media servers 128a-n and the plurality of gateways 112a-n.

Abstract: A vehicle immobilization system has an electronically controlled locking mechanism which requires interconnection with an electrical supply for it to be switched between a locked state and an unlocked state. The locking mechanism remains in the state to which it is switched when disconnected from the electrical supply. The immobilization system includes control means which operates to connect the locking mechanism to the electrical supply to switch it from one state to the other, and to disconnect the locking mechanism from the electrical supply when the vehicle engine is running or the vehicle is moving. The immobilization system also includes means to prevent cranking of the engine when the locking mechanism is in it's locked state.
