Title: Mobile radio receiver for cellular radio telecommunications systems
Inventor: WEDI CHRISTOPH
IPC: H04Q7/32
Filed: 1996-05-29
Granted: 2002-11-26
Abstract: In order to enable a telecommunication connection to proceed without interruption for mobile radiotelephones (MTm) used in a cellular radio-telecommunication system, even when stationary basis stations (U-BS, H-BS) in the cellular telecommunication system are not synchronized (asynchronous radio-telecommunication system), the mobile radiotelephone (MTm) comprises first to third means (FKT, SST, BMC, ZST, µP, SPGM, SWS) permitting reception of all radio messages sent by the basis station (U-BS, H-BS) to the mobile radiotelephone (MTm) for possible radio links at frequencies, in time slots and/or on channels and enabling radio links to be established. Thus, in addition to a first radio link serving as a telecommunication connection, the mobile radiotelephone can establish in the background at least one second radio link.

Abstract: There is provided an adjustable housing for use with a drill string for controlled directional drilling of a well hole. The housing includes an upper sub and a lower sub each having a first portion extending along a primary axis and a second portion extending along a secondary axis offset from the primary axis by a predetermined angle. The second portions are rotatably mounted together such that the secondary axes of the respective upper and lower subs are coincident. The upper sub is thus rotatable in relation to the lower sub between a bent position wherein the primary axes of the upper and lower subs are misaligned and a parallel position wherein the primary axes of the upper and lower subs are parallel to each other. A locking member is slidably mounted on splines extending radially from the second portion of the upper sub such that the locking member is slidable between an engaged position and disengaged position. In the engaged position the locking member engages teeth on the lower sub such that the upper sub cannot rotate relative to the lower sub. In the disengaged position each sub is rotatable in relation to the other.

Title: System and method for implementing local number portability
Inventor: NIMMAGADDA PRASAD V
IPC: H04Q3/00
Filed: 1997-10-30
Granted: 2001-05-08
Abstract: A system and method for routing communications to a terminating station associated with a porting subscriber directory number when the porting subscriber line (14a) is cut-over from a donor switch (12a) to a donee switch (12b). Upon cut-over of the porting subscriber line (14a), a local number portability (LNP) activation telephone call is placed to a dial-in platform (50) that activates a previously provisioned but inactive LNP database entry for the porting subscriber directory number. The LNP database entry is located in an LNP database (42a) at a service control point (SCP) (28a). The dial-in platform (50) also activates a previously provisioned but inactive directory-number-level trigger for the porting subscriber directory number at the donor switch (12a). Activating the directory-number-level trigger for the porting subscriber directory number at the donor switch (12a) causes the donor switch (12a) to hold a subsequently received telephone call directed to the porting subscriber directory number. The donor switch (12a) then transmits a query message to the SCP (28a) and holds the telephone call until it receives a response message including routing instructions from the SCP (28a). Activating the LNP database entry for the porting subscriber directory number in the LNP  database (42a) at the SCP (28a) associates the porting subscriber directory number with the donee switch (12b). Activating the LNP database entry therefore allows the SCP (28) to determine the correct terminating switch for the held telephone call, which after cut-over, is the donee switch (12b).

Abstract: A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding;  member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory response or to deliver a drug.

Abstract: A method of controlling the attitude of a boat at high speed through boat hull design involves a first step of forming a pair of high speed steps in the hull of the boat. The pair of high speed steps provide enough surface area to control ride attitude, while reducing the wetted area of the hull to decrease drag. A second step involves forming transition steps to provide a transition to the high speed steps as the boat accelerates. In addition to reducing drag, the method aids in turning and lifting of the hull by trapping air and water in the steps.

Title: Diversity handling moveover for cdma mobile telecommunications
Inventor: WALLENTIN PONTUS
IPC: H04W36/00
Filed: 1998-11-24
Granted: 2009-09-15
Abstract: In connection with a diversity handling moveover procedure for a cellular system having soft handover, allocation of a replacement diversity handling unit in a target node occurs only after a moveover decision has been made by a source node. Initially, an original or source diversity handling unit at the source node performs connection combining and connection splitting functions for legs of a mobile connection routed through plural base stations serving a mobile station. In accordance with movement of the mobile station, the source node makes the movement decision. The moveover decision can be based on factors such as base station utilization and/or actual and/or predicted directional movement of the mobile station. In some embodiments, the diversity handling moveover procedure involves selection among plural nodes for situs of the replacement or target diversity handling unit.

Abstract: A droplet emitter with an array of droplet emitting devices constructed such that one flowing liquid is used to create the droplets while a second low acoustic impedance liquid can be used to both make the transfer of acoustic energy to the first liquid more efficient and help maintain a uniform temperature of the droplet emitter array. Both the emission fluid and the low acoustic impedance fluid can be circulated through the droplet emitter to allow for excess heat generated by control electronics to be transferred to the flowing. This prevents for instance excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.

Title: Illuminateur pour therapie photodynamique
Inventor: LUNDAHL SCOTT
IPC: A61B5/00
Filed: 1999-04-26
Granted: 2013-10-01
Abstract: L'invention concerne un appareil et un procédé pour la thérapie ou le diagnostic photodynamique, dans lesquels on utilise un illuminateur comprenant plusieurs sources lumineuses épousant généralement la forme d'une surface de forme complexe et exposant ladite surface à une lumière visible d'intensité sensiblement homogène. Les sources lumineuses peuvent comporter des tubes fluorescents généralement en forme d'U, qui sont excités par des ballasts électroniques. Le réglage de la tension des ballasts permet de commander la puissance de sortie des tubes. Lesdits tubes sont supportés par un boîtier en tôle ou en plastique et sont recouverts d'un écran au polycarbonate qui dirige le courant d'air de refroidissement dans l'unité et empêche le contact entre le verre et le patient, en cas de rupture du tube. Un réflecteur en aluminium situé derrière les tubes permet d'augmenter l'irradiance de sortie et l'homogénéité de la répartition de sortie. L'espacement des tubes en forme d'U est modifié, de manière que la sortie au niveau des bords de l'illuminateur soit augmentée pour que la sortie soit plus homogène. Par ailleurs, différentes parties des tubes sont refroidies dans différentes proportions, de manière que l'homogénéité soit améliorée. Un capteur de lumière contrôle la sortie des tubes en U pour produire un signal de réglage de la sortie des tubes.
