Abstract: A dental component attaches to an implant implanted in living jawbone having overlying gingiva. The implant has an apical end embedded within the jawbone and a gingival end near an interface of the gingiva and the jawbone. The dental component comprises a body having a lower region, a gingival region, and a supragingival region. The lower region has an end surface to engage the gingival end of the implant. The gingival region extends through the gingiva and has an outer surface for forming and maintaining an aperture in the gingiva that exposes the gingival end of the implant. The supragingival region has a top surface projecting above the gingiva. The dental component includes first means for receiving a healing element and second means for receiving an impression element. The healing element includes means for fastening the body to the implant so as to allow the gingiva to heal around the body for an extended period of time thereby forming the aperture. The impression element includes an upper segment extending above the supragingival region for receiving impression material and means for securing the body to the implant. Consequently, the dental component serves as part of both a gingival healing component and an impression component.

Title: Immobilized and activity-stabilized complexes of LHRH antagonists and processes for their preparation
Inventor: ENGEL JURGEN
IPC: A61K38/09
Filed: 1998-03-23
Granted: 2003-02-11
Abstract: In this invention, a release-delaying system is to be developed for LHRH antagonists, in particular for cetrorelix, which allows the active compound to be released in a controlled manner over several weeks by complexation with suitable biophilic carriers. The acidic polyamino acids polyglutamic acid and polyaspartic acid were selected for complexation with cetrorelix. The cetrorelix polyamino acid complexes are prepared from aqueous solutions by combination of the solutions and precipitation of the complexes, which are subsequently centrifuged off and dried over P2O5 in vacuo. If complexes having a defined composition are to be obtained, lyophilization proves to be a suitable method. The cetrorelix-carboxylic acid complexes were also prepared from the aqueous solutions. In the random liberation system, the acidic polyamino acids poly-Glu and poly-Asp showed good release-delaying properties as a function of the hydrophobicity and the molecular mass of the polyamino acid. In animal experiments, it was possible to confirm the activity of the cetrorelix-polyamino acid complexes as a depot system in principle. It is thus possible by complexation of cetrorelix with polyamino acids to achieve testosterone suppression in male rats over 600 hours. The release of active compound here can be controlled by the nature and the molecular mass of the polymers.

Title: Communication method and device with pulse position modulation
Inventor: WANG WEI-JENN
IPC: H04B10/06
Filed: 1998-06-09
Granted: 2000-02-21
Abstract: The invented receiver comprises a pulse position modulation encoder, an automatic gain control circuit, and a timing recovery circuit, wherein the pulse position modulation encoder comprises a frequency divider, a slot selector, and a mixer. The frequency divider uses the clock signal and the synchronous non-zero return signal to obtain a half-frequency clock signal by a dividing method. According to the logical value of the non-zero return signal and the control signal, we can obtain a first and a second slot selection signal through the slot selector, the control clock signal and the pulse position of the half-frequency clock signal. The mixer mixes the first and second slot selection signals to generate a pulse position modulation signal of a corresponding inputted non-zero return signal. The automatic gain circuit comprises a variable gain amplifier, a delay quantizer, a delay comparator, an event detector, a timer, and a counter. According to the inputted digital control value, the gain of the variable gain amplifier can be dynamically changed to amplify the pulse position modulation signal received. According to the above control signal, the counter increases its outputted digital control value. The delay comparator detects the signal level of the amplified pulse position modulation signal. If the signal level exceeds a preset dignal level range, the event detector will trigger a next control signal to make the counter decrease the digital control value and reduce the gain of the variable gain amplifier. The timing recovery system includes a frequency tracking device, slot locking circuit, and phase locking circuit. The frequency tracking device generates initial clock signals fx and whose frequencies are determined based on received pulse position modulation signal. The slot selector circuit generates resampling clock fs synchronous to the initial clock signal on slot. The phase locking circuit makes the previously generated initial clock signals and the received pulse position modulation signal synchronous in phase.
