Title: Slave driving force-transmitting mechanism for vehicle
Inventor: KITA KANJI
IPC: B60K17/34

Granted: 2000-10-03
Abstract: Tri-port joints, each of which includes revolvable rollers to be directly fitted to outer circumferential surfaces of spider shafts, are provided respectively at both ends of an input-side shaft to which slave driving force is transmitted.  Accordingly, it is possible to prevent a slave driving system from transmission of unnecessary torque, and obtain a slave driving force-transmitting mechanism which is compact and light in weight, having a structure simplified as compared with those of the conventional technique.

Abstract: An interlock assembly for use with two or more vertically arranged drawers mounted on telescopic slides in a housing such as a cabinet so as to prevent the extension of a drawer once another drawer is opened. The interlocking system interfaces with the stationary members of vertically arranged slides attached to the cabinet. A pair of opposing upper and lower actuator followers are slidably and transversely fitted near the front of the stationary members so that movement of one actuator follower toward the other, displaces the other. A rod connects the upper actuator follower of one slide with the lower actuator follower of a slide directly above it. An actuator is connected to the front ends of the telescopic members of the slides. As a telescopic member is extended, the actuator of that slide makes contact and displaces the upper actuator follower of the slide which results in the upper displacement of the lower actuator followers of the slides directly above the extended slide. The extended slide also prevents the upward displacement of the upper actuator followers of all the slides directly below it. Consequently, all actuator followers block the path of their respective telescopic members precluding their extension.

Abstract: An electrically small antenna is disclosed that is constructed from a generalized contrawound toroidal helix (1, 2) made from a single continuous conductor divided into two length portions each of which are substantially the same length and which have a generalized helical pattern. The helical pitch senses the two length portions are opposite to one another. The two length portions are insulated from one another and overlap one another on the surface of a generalized toroid. A signal is fed to the antenna at a port defined by the node locations (N1, N2) where the respective length portions join one another, or at a diametrically opposite point. A compact, broadband embodiment of the antenna is disclosed, as are other applications including a coaxial cavity resonator using the antenna as a feed element.

Abstract: Input audio signals are subjected to integration of the order of an even number by one or plurality of even order integrators and the input audio signals are subjected to differentiation of the order of an even number by one or plurality of even order differentiators. The even order integration signals subjected to the even order integration and the even order differentiation signals subjected to the even order differentiation are added to the input audio signals with the same phases or opposite phases. Thus, the expected frequency-gain characteristics can be obtained while the phase relations between the frequency components of the input audio signals in particular the intermediate audio frequency range, a part of the low audio frequency range near the intermediate audio frequency range, and a part of the high frequency range near the intermediate frequency range are maintained, so that the high grade sound quality can be achieved.

Title: Methods for enhancing functional recovery following central nervous system ischemia or trauma
Inventor: CHARETTE MARC F
IPC: A61K38/22
Filed: 1997-03-21
Granted: 2011-11-08
Abstract: The present invention provides methods and compositions for treatment of mammals afflicted with an ischemic or traumatic injury of the central nervous system. The present invention capitalizes in part upon the discovery that administration of a morphogen to such a mammal provides significant improvement in central nervous system function, even when administered after central nervous system tissue has been damaged. The methods involve the administration of dimeric proteins defined as morphogens, inducers of these morphogens, or agonists of the corresponding morphogen receptors, or implantation of cells stimulated by exposure to the morphogens. The proteins defined as morphogens comprise a structurally and functionally distinct family within the TGF-.beta. superfamily. Osteogenic protein-1 (OP-1) is considered to be an exemplary and preferred member of this morphogen family.

Abstract: The present invention concerns an LED spectrometer operating without moving parts, according to the sweep principle, and appropriate to serve as a structural component in many kinds of spectroscopic concentration analysers. The design of the invention affords the advantage that, even at its minimum, the optical power of the LED spectrometer of the invention is about fivefold compared with designs of prior art. Furthermore, improvement of the efficiency of the LED radiation source and of that of the optics has brought a multiple augmentation in power to the wavelength spectrum sent out by the radiation source. In the design of the invention, concentrators (6) of non-imaging type are used to collimate the wavelength spectrum emitted by the LEDs (3).

Inventor: JONES RAYMOND K
IPC: H04N21/43
Filed: 1999-07-22
Granted: 2002-06-18
Abstract: Synchronization among digital video and digital audio signals is maintained in a multimedia player with limited or highly varying processing power. In an exemplary embodiment of the invention, a processor with stored program memory controls the decoding and playback of audio blocks and video frames, each stream independently stored in an order of intended playback time. The processor gives priority to the decoding and playback of audio blocks, and periodically determines whether a backlog of encoded video frames exists.  Under video backlog conditions, the processor reduces the backlog by decoding only those backlogged video frames that must be decoded in order to decode and play the frame in the sequence of backlogged video frames with the latest intended playback time. After decoding this latest backlogged frame, the processor directs it to be played. Normal video decoding and playback then resumes for video frames following this latest backlogged video frame in sequence and in intended playback time.
