Title: Caller information (clid) controlled automatic answer feature for telephone
Inventor: BRENNAN PAUL MICHAEL
IPC: H04M1/60
Filed: 1997-10-30
Granted: 2002-08-20
Abstract: On receiving a new call, a controller in a telephone station apparatus compares the incoming caller information with caller information in stored records.  On a match, an associated name is spoken over a handsfree speaker and then the controller places the telephone station apparatus in a handsfree off-hook condition.  In this way, someone in a hands-busy situation or a handicapped individual may have calls from pre-selected callers automatically connected.  The controller may also store a two-way or one-way communication path indication with each record and, accordingly, establish either one-way communication path from the calling party to the telephone station apparatus or a two-way communication path to and from the telephone station apparatus.

Granted: 2005-12-20
Abstract: A mechanical-hydraulic double-acting drilling jar includes an inner tubular mandrel (12)telescopingly supported inside an outer tubular housing (14). The mandrel and the housing each consist of a plurality of tubular segments joined together, preferably by threaded inner connections. Upper (134) and lower (166) pressure pistons are slidably disposed within the housing, respectively closing upper and lower substantially sealed hydraulic chambers (132,164). Longitudinal movement of the mandrel engages the collet (184), which in tum, translates either the upper piston (134) or the lower piston (166), depending on the direction of mandrel movement. As one of the pistons is moved, fluid pressure builds in the associated hydraulic chamber, retarding further movement of the mandrel, enabling potential energy to build in the drill string. The collet is restricted from expanding until the mandrel reaches a particular point in the housing, at which time the collet expands, releasing the mandrel to rapidly collide a hammer surface (32,21) thereon with an anvil surface (44,41) in the housing.

Patent CA-2238717-C (CA)
Inventor: EKSTROM MICHAEL P
IPC: G01V11/00
Filed: 1997-01-16
Granted: 2000-03-21
Abstract: A system and method for evaluating a geological formation is described which compares actual wireline log measurements from a number of wireline logging tools to predicted tool response logs. The system and method uses a forward model of each tool response, given a formation description, to predict a set of wireline logs. Comparing the predicted logs with the actual measured logs yields a mismatch error. The system and method iteratively adjusts the formation description to minimize the mismatch error to obtain a "best" formation description. In one form, the formation description includes petrophysical properties (porosity, density, saturation) and geometry properties (dip, bedding, invasion). In a more complicated form, the formation description also includes a model of petrophysical mixing laws and formation material content. In the special case of a horizontally layered formation and linear tool response models, there exits a computationally efficient version of the system and method.

Title: Communication method, data transmission method and data communication system
Inventor: NAGAI TETSUYA
IPC: H04L27/00
Filed: 1998-07-03
Granted: 2003-10-28
Abstract: To perform communication at a higher speed than in the past using a new communication device without giving influence on the existing slave communication device, on a master device of a communication system such as PHS, there are provided two series of modulators and demodulators for conventional speed and for higher speed, the two different speeds being changeable by a changeover switch. A slave device to be added newly is also designed in almost the same configuration. In the link setup phase, an information to request change of modulation method is notified together with a request of communication from the slave device to the master device. From the master device, an information to specify time slots to be used in the communication phase and an information to specify modulation method are notified to the slave device. In the communication phase, communication is performed using the modulation method and the time slots as specified. The slave device can select the modulation method corresponding to the transmitting speed as required. In case the modulation method is not specified from the slave device, the same modulation method as that of the link setup phase is used in the communication phase, and the existing slave device not equipped with the means to specify the modulation method can be used without any change.

Abstract: A method and apparatus provide for selective encryption between a user and a network ingress/egress point or between a service provider and such an ingress/egress point. Software modules in a peer interface permit selective activation of encryption for particular socket connections. The peer and the ingress/egress point then exchange information such as an encryption key to facilitate the transfer of encrypted information between the peer and that point. Since the network itself is secure, transfers within the network can be performed with decrypted data. However, if information is to be transferred again outside of the network then the data could be encrypted at the egress point.
