Systems, devices, and methods for contextual management extract context information and content information from a collection of stored digital content items; generate an index of the extracted context information and content information; store the indexed context information and content information; receive a query from a computing device, wherein the query is associated with a user; determine a context of the user; determine a context of a user activity; determine contents of the query; generate a recommendation in response to the query based on the context of the user, the context of the user activity, and the contents of the query; and return the recommendation to the computing device.

An information processing apparatus, which is configured to communicate with a server apparatus and an image forming apparatus, comprises a receiving unit configured to receive AR information that includes AR guidance for a first operation of an image forming apparatus, wherein the AR information superimposes the AR guidance on an image that was captured by the information processing apparatus; a display control unit configured to command the information processing apparatus to display the AR guidance to guide a user to operate the image forming apparatus, and an obtaining unit configured to obtain information that originated from performance of the first operation by the image forming apparatus, wherein the receiving unit is further configured to receive AR information that includes additional AR guidance that presents operations for recovering from the error.

Network communications face security issues including traffic flow analysis attacks. Such attacks include deduction of information about networks through analysis of transmitted traffic volume or statistics, even if the traffic is encrypted. For example, an adversary may deduce operational information from traffic volume, or its timing. Described herein are security techniques that can provide transmission security with an obfuscating 'cover' signal for any contention-based multiple access system by employing signal interference cancellation techniques, but are not so limited. The cover signal is transmitted on the same frequency band used by terminals on the network. Using 'known-signal' and/or self-interference cancellation techniques, the cover signal can be removed by authorized terminals that have appropriate cover signal information and timing synchronization. An adversary cannot distinguish between real traffic and the cover signal while authorized terminals can recover transmissions without impact to network capacity.

Embodiments of the invention provide for encryption and decryption of data in a TDMA network using TDMA time values. In some embodiments, TDMA time values can be transmitted to terminals from a network controller using a burst time plan. These TDMA time values along with other data and/or counters can be combined to create a one-time key, which can be used to both encrypt data and/or decrypt data. Embodiments of the invention can decrease communication overhead by using the TDMA time value for TDMA purposes as well as for encryption purposes.

An engine with a valve opening arrangement includes an engine including at least one cylinder and at least one valve for opening and closing an opening in the cylinder. The valve is spring loaded to a closed position. The engine also includes a movable contact surface for urging the valve to an open position, and a control arrangement at least partially connected to the contact surface and operable in a modified mode to at least one of advance opening and delay closing of the valve relative to opening and closing in a normal mode.

Valve opening arrangement and method

An arrangement that provides power to an electrical device includes an inverter, first and second switches, and a bypass controller. The first switch has open and closed positions, and is operable to connect the inverter to the electrical device when in the closed position. The second switch has open and closed positions, and is operable to connect a utility power line source to the electrical device when in the closed position. The bypass controller is operable to cause a transition sequence in which the first switch changes to the open position and the second switch changes to the closed position. The bypass controller is further operable to: cause continuous actuation of a first indicator when the first switch is closed; cause continuous actuation of a second indicator when the second switch is closed; and cause intermittent actuation of the second indicator during at least part of the transition sequence.

A diversity antenna assembly for use with portable radiotelephones includes plural antennas physically connected by a non-conducting member to effect simplicity of deployment of the antenna assembly. The antennas are spatially separated to provide space diversity to minimize the deleterious effects of Rayleigh fading.

A metal door frame has trim molding applied to its flanges by the aid of separate clips. Each clip interfits an aperture in the flange and a notch at the flange edge. The aperture and the notch are punched in the flange so that the spacing thereof from the corner of the flange is constant whereby alignment of the clips is assured notwithstanding lack of critical dimensional control of the flange.

A filter bag pressure vessel having a filter bag that affords significantly more filter area than the conventional filter bag per equal unit area of volume displacement. The arrangement incorporates a center feed that permits a positive 360.degree. sealing of the inlet and filter bag between two parallel surfaces with a single sealing means that eliminates close tolerances and other requirements that were utilized in the prior art constructions. In addition, the filter bag and supporting structure can be adapted to fit within existing pressure vessels.
