Patent TW-411662-B (TW)
Title: Electronically commutated engine
Inventor: BERNAUER CHRISTOF
IPC: H02P6/14
Filed: 1998-06-16
Granted: 2000-11-11
Abstract: An electronically commutated engine comprising a stator carrying several winding phases and a rotor. The individual winding phases can be controlled through final power stages over time-delayed periods divided into control times and dead times. To reduce power loss during the final power stages and, thus, to raise effectiveness, especially in the case of heavy currents, the invention provides for the control periods to be divided into an initial period and an end period. When the engine currents are low, clocking by pulse-width modulation occurs only during the initial or end periods, whereas, when currents are heavy, the current is fully switched through during the initial periods and additionally for a more or less long part of the end periods or during the end periods and additionally for a more or less long part of the initial periods.

Title: A packet-based telemedicine system for communicating information between central monitoring stations and remote patient monitoring stations
Inventor: PEIFER JOHN W
IPC: G16H40/67
Filed: 1998-09-21
Granted: 2000-08-01
Abstract: The present invention provides a packet-based telemedicine system for communicating video, voice and medical data between a central monitoring station and a patient monitoring station which is remotely-located with respect to the central monitoring station. The patient monitoring station obtains digital video, voice and medical measurement data from a patient and encapsulates the data in packets and sends the packets over a network to the central monitoring station. Since the information is encapsulated in packets, the information can be sent over multiple types or combinations of network architectures, including a Community access Television (CATV) network, the Public Switched Telephone Network (PSTN), the Integrated Services Digital Network (ISDN), the Internet, a local area network (LAN), a wide are network (WAN), over a wireless communications network, or over an asynchronous transfer mode (ATM) network. Thus, a separate transmission protocol is not required for each different type of transmission media. Rather, a single transport/network layer protocol is used for encapsulating the information in packets at the sending end and for de-encapsulating the information at the receiving end. Furthermore, by sending the information in packets, the video, voice and measurement data can be integrated and sent over a single network.

Title: Method and apparatus for fast recovery from loss of lock in a phase locked loop
Inventor: SIMON HARRIS
IPC: H03J7/20
Filed: 1998-10-30
Granted: 2000-09-21
Abstract: Fast recovery is provided from transient loss of a received carrier in a satellite or terrestrial modem. A carrier tracking loop, loop filter and steering loop are provided in the modem. The occurrence of a transient condition affecting the carrier tracking loop is detected. The loop filter is flushed in response to the transient detection for a time period dependent upon an anticipated length of the transient condition. A voltage of the loop filter is steered toward a predetermined pre-transient value during the flushing step to minimize any change in frequency of the carrier tracking loop when the loop filter is flushed. After the filter has been flushed, the carrier tracking loop attempts to quickly reacquire the carrier.

Title: Completed fixed codebook for speech encoder
Inventor: GAO YANG
IPC: G10L19/12
Filed: 1999-08-21
Granted: 2001-09-11
Abstract: A multi-rate speech codec supports a plurality of encoding bit rate modes by adaptively selecting encoding bit rate modes to match communication channel restrictions. In higher bit rate encoding modes, an accurate representation of speech through CELP (code excited linear prediction) and other associated modeling parameters are generated for higher quality decoding and reproduction. To achieve high quality in lower bit rate encoding modes, the speech encoder departs from the strict waveform matching criteria of regular CELP coders and strives to identify significant perceptual features of the input signal. To support lower bit rate encoding modes, a variety of techniques are applied many of which involve the classification of the input signal. For each bit rate mode selected, pluralities of fixed or innovation subcodebooks are selected for use in generating innovation vectors.

Title: Optically integrating pixel microstructure
Inventor: BISCHEL WILLIAM K
IPC: G09G3/20
Filed: 2000-09-01
Granted: 2002-03-21
Abstract: An integrated optical microstructure includes a substrate carrying an optical waveguide and supporting a medium disposed to receive optical energy from the waveguide. The medium includes an optical re-radiator such as a phosphor, which re-radiates optical energy in response to optical energy received from the waveguide. The structure further includes a reflector disposed to redirect some of the input optical energy emanating from the medium back into the medium, to achieve spatial confinement of the input light delivered by the input waveguide. The structure can thereby increase the efficiency of the light conversion processes of re-radiating materials. An aperture in the reflector permits optical energy emitted by the re-radiator to emerge from the structure and to propagate in a preferred direction, such as toward a viewer or sensor. The structure is useful for increasing the brightness of various kinds of small emissive elements which are excited by light delivered from an integrated optical waveguide, including pixels in an information display.

Title: Operation assisting apparatus and refrigerator
Inventor: MATSUSHIMA TOSHIHARU
IPC: E05F15/614
Filed: 2000-06-08
Granted: 2002-01-01
Abstract: The present invention provides a kind of assisting operation apparatus for a protruded member so as to prevent the reception of too heavy load when the protruded member is protruded forwards and back to the original position. The solving means includes the followings: for the protruded member 9 of the operation assisting apparatus 1, by contacting the switch device 4, the operation of the switch device 4 is assisted. After that, a worm rod 13, which is coupled integrally and rotates together with an output shaft 7a of the motor 7 through a slip mechanism, is provided on the gear wheel train 8 in between the motor 7 and the protruded member 9. A coiled spring 26, which has one end stopped by the output shaft 7a and the other end served as a free end, of the slip mechanism is pressed inside a wall section 13e of the worm rod door so as to operate by following the protrusion of the protruded member 9. When transmission torque from a motor 7 to a protruded member 9 is smaller than a predetermined value, the coiled spring 26 is rotated together with both the output shaft 7a and the worm rod 13 owing to frictional force; and, if the load of the protruding member 9 is increased to make the transmission torque exceed the predetermined value, the coiled spring 26 is not rotated together with both the output shaft 7a and the worm rod 13 owing to slide. A worm wheel 31a that engages with the worm rod 13 is provided on the gear wheel train 8. When action of pushing back to the original position is conducted onto the protruded member, and even the external force applied to the push member 9 is transmitted to the worm wheel 31a, the worm rod 13 is subjected to this force such that the tooth lead angle of the worm rod 13 is enlarged and the worm rod 13 is able to rotate in the reverse direction.
