Abstract: The present disclosure describes techniques for determining whether a communication request is associated with a legitimate communication or spoof communication, prior to establishing the connection. A Parallel Path Caller Verification (PPCV) controller is described that is configured to intercept a communication request from an originating device and generate a proof-of-identity (PoI) message for delivery to the originating device. Upon receipt of a reply message that is responsive to the PoI message, the PPCV controller may determine whether the communication is a legitimate communication. If the communication is determined as legitimate, the PPCV controller may establish a communication based on the communication request.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing a telephone call screener are disclosed. In one aspect, a method includes the actions of receiving a telephone call. The actions further include determining characteristics of the telephone call. The actions further include, based on the characteristics of the telephone call, determining a level of screening to apply to the telephone call. The actions further include determining screening data based on screening the telephone call according to the level of screening. The actions further include providing, for output, the screening data.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing menu-based communication are disclosed. In one aspect, a method includes the actions of receiving, from a first computing device, a communication and data identifying a second computing device as a recipient of the communication. The actions may further include determining a first and second candidate response to the communication. The actions may further include providing, to the second computing device, the communication, the first and second candidate responses, and instructions to provide, for output by the second computing device, the first and second candidate responses as selectable responses to the communication. The actions may further include receiving, from the second computing device, the selection of the first or second candidate response.

Abstract: Described herein are techniques for enabling remote implementation and enforcement of usage settings on one or more user devices. In some embodiments, a wireless carrier network maintains information on relationships between various user devices. Each relationship may be active under specified conditions (e.g., time and/or location) and is associated with usage settings that dictate one or more rules to be enforced while the relationship is active. In some embodiments, a set of usage settings may be generated for a particular user device based on all active relationships associated with that user device. The set of usage settings may be enforced by a mobile application installed upon a user device or by a wireless carrier network that blocks certain network traffic to and/or from the user device.

Abstract: An apparatus is provided that comprises a vibrating member (402). The vibrating member (402) is for a vibrating densitometer (400). The vibrating member (402) includes one or more apertures (420). The one or more apertures (420) are sized and located in the vibrating member (402) to increase a frequency separation between a resonant frequency of a desired vibrational drive mode and a resonant frequency of one or more undesired vibrational modes.

Abstract: A moisture and dust removing louver pack is composed of a set of pivotable louvers which can pivot between open and closed positions in an air passageway, the louvers allowing air to pass through the passageway when in the open position and having moisture and dust removing structure for air to impinge upon to remove moisture and dust from the air passing through the passageway.

Abstract: The invention provides a method of calibrating a vibrating tube densitometer intended to operate at combined elevated temperatures and pressures.

Abstract: A method and system for selecting an external user interface using spatial information is described. In one configuration the floor space of a mailroom is mapped using a two dimensional grid. At least one machine is located on the mapped grid and an associated control zone is defined for that particular machine. The machine includes a wireless transceiver for providing user interface access. An external portable processor with a wireless transceiver is provided with user interface logic for the machine. A user then moves the external portable processor into the control zone of the machine. An indoor positioning system is utilized to provide relative or absolute position information relating to the machine and the external processor. The system determines that the external processor is in the machine control zone and allows the external processor to function as a user interface for the machine.

Abstract: A system for detecting failures in a sensitive region of an inkjet printhead is described. The system includes an inkjet printer that uses a printhead for printing an image on a substrate. The image has a sensitive portion that is more sensitive to printing failures than the rest of the image. The printhead includes a first portion that prints an area of the substrate corresponding to the sensitive portion of the image. A radiant energy source is used with a photodetector located downstream from the printhead to detect background florescence from the substrate in the area of the substrate corresponding to the sensitive portion of the image that should be quenched by printing of the image. If background florescence is detected, a failure is indicated.

Abstract: A mailpiece is received in a stream of mail. The mailpiece has a postage stamp thereon. The stamp includes an image. Automatic mail handling equipment detects that the image was identified as being a problematic image and removes the image from the mail stream.

Abstract: A hose clamp installation tool and a method for installing a hose assembly. A first rod engages the clamp and releases the clamp from an open position to a closed position. A sensor indicates release of the clamp.

Abstract: A sealing device for use with a drive shaft of a water vessel. The sealing device comprises a housing for a seal and bearing, a compression ring, a lip seal flange attachment and a diaphragm for tracking the movement of the shaft. The diaphragm is made of a resilient, flexible material and is operatively connected to the seal housing. In operation, the diaphragm tracks the motion of the drive shaft so that the drive shaft may move freely in the hull of the vessel. The diaphragm allows the rigid seal housing to also move in response to any axial, lateral or circular-axial (wobble-like) movement of the shaft so that a constant seal around the shaft is provided.

Abstract: A hose clamp installation tool and a method for installing a hose assembly. The hose clamp installation tool includes a hook that engages a clamp. A first rod engages the clamp and releases the clamp from an open position to a closed position. A sensor indicates release of the clamp.
