Patent CA-2063930-C (CA)
Title: Synchronous digital signal to asynchronous digital signal desynchronizer
Inventor: BERNARDY EDMOND
IPC: H04L7/00
Filed: 1992-03-25
Granted: 1998-09-15
Abstract: Improved jitter performance is realized in a desynchronizer for obtaining an asynchronous signal, e.g., a Conference of European Posts and Telecommunications (CEPT)-4 signal, from a received synchronous signal, e.g., a Synchronous DigitalHierarchy (SDH) Synchronous Transport Module (STM)-1 signal. The improved jitterperformance results from employing a unique gap generator which causes gaps in areceived data signal to be spread regularly in time, and allows for almost continuous control by numerical techniques of the phase of a smooth output clock being generated. Phase control is obtained by employing a filtered version of the difference between the actual number of data bits in the received digital signal and the expected nominal number.

Granted: 2002-04-02
Abstract: A humidifier including a base defining a reservoir for retaining a liquid volume having an upper surface; a humidification unit removably mounted on the base and having an electrically energized humidifier adapted to induce dispersion of liquid retained by the reservoir, and a switch adapted in an active condition to energize the humidifier and in an inactive condition to cause deenergization thereof; and an actuator retained by the base and adapted for movement between activating and inactivating positions with respect to the switch, the actuator adapted in its activating positions to actuate the switch into its active condition and in its inactivating positions to actuate the switch into its inactive condition and wherein both given changes in the level of the upper surface and movement of the humidification unit relative to the base produce the controlling movement of the actuator.      Mounting of a switch on a removable humidification unit and an actuator for the switch in a base supporting the unit facilitates desired shut-off in response to either an inadequate water supply or removal of the unit.

Patent CA-2092253-C (CA)
Inventor: SCHMODE HARTMUT
IPC: H01R43/045
Filed: 1993-03-23
Granted: 1996-09-03
Abstract: The invention relates to pliers for dressing conductor ends, having a pair of handles, moveable relative to one another, a plurality of dressing stations for the conductor ends, and having a drive device via which the dressing stations can be driven during operation of the handles. One of the dressing stations is constructed as a crimping drum which can be displaced axially, and is supported such that it can rotate, can be coupled to the drive device in the axially displaced position over only one dressing process, and, in this position, can be locked via a flange which projects radially from it.  This flange extends over the overall circumference of the crimping drum and has at least one recess.  A locking tab, which is arranged in a fixed position on the body of the pliers and is radially opposite the flange,  engages,  in the undisplaced axial position of the crimping drum,  into the recess, to be precise up to a point close to the outer surface of the crimping drum while, in the axially displaced and rotated position of the crimping drum, the locking tab comes to rest above the outer surface of said crimping drum and engages behind the flange.  Locking of the crimping drum both  in  the  rotational  direction  and  in  the  axial displacement direction is thus possible by means of the locking tab.

IPC: H04W88/02
Filed: 1993-10-15
Granted: 1999-12-14
Abstract: A compact telephone, which may be fastened to a user's wrist by means of a strap 310, 320, includes a case 100 having an upper portion 110 that is hinged along one edge to a lower portion 210. A receiver transducer 140 is embedded within the upper portion on the side opposite the hinge, and a microphone transducer 240 is embedded within the lower portion on the side opposite the hinge so that the distance between them is maximized when the case is opened. By providing such separation, inter-transducer distance is increased, and this results in improved signal-to-noise performance. Such performance is further improved by using a directional microphone which is more responsive to sounds coming from the direction of the user's mouth than from other directions.

Granted: 1998-07-28
Abstract: A high-frequency choke circuit comprises a dielectric layer covered with grounding conductors, a lead line of high-impedance and capacitance lands formed within the dielectric layer, and through-holes connecting the lead line and the capacitance lands.  The capacitance lands are disposed closer to the grounding conductors, resulting in large capacitance with small areas.  The capacitance lands are formed on a layer distant from the layer on which the lead line is formed.          Therefore, unnecessary electromagnetic coupling with other circuits formed on the same layer as the lead line can be reduced.  The grounding conductors cover both surfaces of the dielectric layers that incorporate the capacitance lands and the lead line to thereby shield the circuit formed in the dielectric layers electromagnetically from outside.
