Abstract: A more precise determination of bulk formation density is attainable using a pulsed ?-? density tool and simultaneously compensating for interactions due to photoelectric effect and density variations caused by standoff. A source directs energetic particles at a formation having a known photoelectric factor and electron density. One or more photons either emitted or deflected from the formation are captured at a first or second detector, respectively spaced at first and second distances from the source, and separated from each other by a third distance. First and second total energies of the photons respectively striking the first and second detectors are measured during a time interval. A first filter is disposed between the first detector and formation effective to cause Pe response to match standoff influence, thereby compensating for both effects simultaneously. In some embodiments, a second filter is provided between the second detector and formation.

Abstract: A method and system for conferencing a landline telephone into a cellular telephone call is disclosed. In response to a landline telephone going off-hook, a cellular telephone corresponding to the landline telephone is identified. When a determination is made that the corresponding cellular telephone is currently engaged in a call, the landline telephone is conferenced into the cellular call. If the cellular telephone is subsequently disengaged from the call, the original cellular call has been effectively transferred to the landline telephone. The inventive method and system may be linked to a cellular-landline conference call service. For example, a user may subscribe to such a service so that the user may automatically transfer a call from the user's cellular telephone to the user's home or office landline telephone when that landline telephone is taken off-hook.

Abstract: Users of the system are each provided with an indicator module capable of presenting a display. An authorization module keeps track of which users are authorized to access a facility, such as a secured area or a parking facility. The authorization module sends messages, such as SMS messages, to the authorized indicator modules directing them to present a common valid display. The common valid display changes repeatedly over time, but, at any one time, the modules of authorized users all present the same display. A user may be granted or denied access based on whether the display on his module is the same as that of known authorized modules.

Abstract: A method and apparatus for transitioning between radio link protocols in a packet-based real-time media communication system. A wireless communication device such as a cell phone will operate under one radio link protocol (such as IS-856, also known as 1xEV-DO) to engage in packet-based signaling for setup of a packet-based real-time media session such as a push-to-talk session. Once the session is set up, the wireless communication device will then automatically transition to operate under a different radio link protocol (such as IS-2000, also known as 1xRTT), and will engage in packet-based real-time media communication in the session over that different radio link protocol. Preferably, the radio link protocol used for session setup signaling will provide for reduced setup latency, while the radio link protocol used for bearer communication in the session will provide for reduced jitter and improved real-time media communication.
