Abstract: A wireless sensor preferably has a case which is intrinsically safe and has no exposed parts which can become not intrinsically safe due to the passage of time or through contact with chemicals typically encountered in a location where the wireless sensor is used. It preferably has no integral visual display other than lights, and it preferably includes at least one signal light. The sensor preferably includes a wireless transceiver for allowing remote read and remote control of the sensor. The sensor preferably includes piezoelectric pressure detectors for allowing a user to locally interact with the sensor by pressing on the case. Data can be automatically harvested from the sensors by a portable electronic data-retrieving device which is usually geographically remote from the sensors when the portable electronic data-retrieving device and the sensors are in range of a wireless system which allows them to communicate when they are geographically proximate each other.

Abstract: A system for exploring data receives the data from a database and indexes the data in a server. The system displays one or more selectable datasets from the indexed data, where the selectable datasets include a plurality of attributes. The system receives a selection of one of the plurality of attributes. The system then sorts the one or more attributes by level of interestingness relative to the selected attribute, and displays the sorted attributes.

Abstract: An Internet of Things management system is described that allows organizations to remotely monitor and configure a fleet of devices. In one embodiment, the system includes a services layer executed by a computing platform that communicates with mobile devices such as smart phones via a network interface. Beacon devices may be deployed to broadcast a location identification within an organization's site to the mobile devices, which location may then be communicated to the services layer.

Abstract: In one implementation, a method for implementing gain control enhancement for modulated communications includes establishing a communication session between a first endpoint and a second endpoint. The communication session involves forwarding a call signal using an initial gain level until a state transition is detected in the communication session at a digital signal processor. The detection may occur in a transmitting gateway associated with the first endpoint or a receiving gateway associated with the second endpoint. The state transition indicates modulated communications, which may include fax, modem, or text telephony. For example, communication session may be fax over IP (FoIP). The call signal is forwarded using an adjusted gain level based on the state transition. The adjusted gain level may be selected to avoid clipping in the call signal.

Abstract: In one embodiment, an originating gateway receives a call menu (CM) signal from an originating fax machine. The CM signal may have been generated in response to an ANSam signal from a terminating fax machine. The originating gateway suppresses the CM signal after a preamble of the CM signal and generates a modified JM signal in response to receiving the CM signal. The modified JM signal indicates that V.34 half-duplex modulation is not an option. The originating gateway transmits the modified JM signal to the originating fax machine, which allows the transmission to continue across an unenhanced T.38 fax relay.

Abstract: In one embodiment, a method for discriminating between a machine generated multi-tone signal and a simulated voice multi-tone signal is provided. The method may comprise comparing output profiles generated from sampled outputs of a plurality of filters. The plurality of filters may have a single input sample stream applied to them and each filter may be preset at a measured multi-tone frequency associated with an identified prospective multi-tone signal. Based on the comparison of the output profiles, an inequality degree between the output profiles is generated and compared to an inequality threshold, thereby to determine whether the input sample stream comprises a machine generated multi-tone signal.
