Abstract: In one embodiment, a depassivating circuit includes a battery, a resistive load coupled to the battery, and a magnetic field sensor. The magnetic field sensor detects a presence of a magnetic field. The magnetic field sensor depassivates the battery by causing current from the battery to flow through the resistive load, in response to the presence of the magnetic field. The magnetic field sensor detects removal of the magnetic field. The magnetic field sensor ends depassivation of the battery, in response to the removal of the magnetic field.

Abstract: Systems and methods for applying Electric Network Frequency (ENF) forensic techniques to determine characteristics associated with an audio and/or video recording such as when and where the recording was made. In one embodiment, a system that determines at least one of a time and a location associated with a recording includes an ENF forensic database, an ENF extraction processing module and a comparison processing module. The ENF forensic database stores powerline data collected from at least one electrical power grid. The ENF extraction processing module extracts ENF content coupled into the recording. The comparison processing module compares the extracted ENF content with powerline data retrieved from the ENF forensic database and outputs information including one or more of a time during which the recording was made and a location where the recording was made based on the comparison with the powerline data.

Abstract: Network hardware devices organized in a Wireless mesh network (WMN) in which the network hardware devices cooperate in distribution of content files to client consumption devices in an environment of limited connectivity to broadband Internet infrastructure are described. One mesh network device includes a micro controller, RF radios, and antenna switching circuitry. The antenna switching circuitry, in response to the control signals from a micro controller, selectively couples individual ones of a first set of antennas to individual channels of the set of RF radios to communicate content data with client consumption devices and selectively couples individual ones of a second set of antennas to other individual channels of the set of RF radios to communicate content data with other mesh network devices in a WMN.

Abstract: Methods and systems for transmitting and receiving data using audio devices but without being detectable by a human ear are disclosed. For example, a device for transmitting data can include a modulator configured to transform digital data into a modulated signal having a frequency no less than about 20 kHz, and an audio transmitter coupled to an output of the modulator configured to transmit the modulated signal into a sound propagating medium without being detected by a human ear. The methods and systems can be used to perform two-factor authentication for permitting a user to access a remote server or other device.

Abstract: Methods and systems for communicating data between a server and a remote client computer through a secure socket layer (“SSL”). In accordance with the present invention, server-side SSL functions are performed by a network device located remotely from a secure data center, while maintaining the secure use of centralized certificates and their associated private keys. The invention may be employed in conjunction with acceleration functions operating within coordinated network devices, facilitating acceleration of overall SSL traffic. The invention improves on the prior art by allowing the remotely located acceleration device to use the certificate and private key of the target application server, but without compromising the security of the server's private key.

Abstract: A hot and cold beverage maker has apparatus for preparing a hot beverage and a beverage jug into which the hot beverage is dispensed and cooled. The jug has an outer receptacle having an outer receptacle wall and a base and an inner receptacle for receiving a cooling agent. The inner receptacle is removably located within the outer receptacle and has an inner receptacle wall together with the outer receptacle wall defining a beverage compartment for receiving the hot beverage to be cooled. A rotational paddle is located within the beverage compartment between the inner and outer receptacle walls for stirring a beverage in the beverage compartment. There may also be a rotational blade within the inner receptacle for agitating the cooling agent.
