Abstract: 643,168. Hinges. SVARTVIKS AKTIEBOLAG. Aug. 1, 1947, No. 21035. Convention date, June 2. [Class 65(ii)] In a hinge adapted to mount a window on a horizontal axis and to provide a braking effect during at least a part of the opening movement thereof, a lever transmits a braking force derived from the weight of the window, the arrangement being such that said force is greater than the braking force which would occur if the window were supported directly by a braking surface. A window 2 carries a pin 15 pivotally supported by a sector plate 6 which is pivoted on a pin 5 fixed to the frame 1. In a partly open position of the window (as shown), a pin 19, fixed to the frame and projecting through a slot 21 in the plate 6, engages a lever 9 pivoted at 8 to the plate 6 and thus urges a brake surface 11 on the lever against an arcuate flange 12 fixed to the window concentrically to the pin 15. Further pivoting of the window about the pin 5 is thus braked. In a modification the pin 19 is carried by the lever and cooperates with a surface provided on the frame.

Title: Encoding information in midamble shifts
Inventor: KOURTIS STAMATIS
IPC: H04J13/16
Filed: 2000-06-28
Abstract: The present invention is suitable for use with communications systems which combine Spread Spectrum and Time Division technologies, for example UTRA TDD. In such systems data is transmitted in bursts, each burst including a set of spreading codes and a midamble. However only a subset of the spreading codes may be active. In the present invention the midamble is coded with midamble shifts which provide an indication of which spreading codes are active. A signalling scheme is employed in which a transmitted midamble is shifted by first, S<SB>1</SB>, and second, S<SB>2</SB>, pointer signals which signal respectively the last code belonging to the subset of active codes and the number of codes in the original set which are not in the active subset. This provides the following advantages: not only does the receiver know the number of active codes, but also it knows (as indicated by the first midamble shift) which of the original set of codes it has to search in order to find the active codes. In order to reduce possible ambiguities a third shift, S<SB>3</SB>, may be used to indicate whether the number of codes in the set is even or odd.

Title: Microactuator-induced reactive forces for fine positioning a sensor
Inventor: TRAVIS E ELL
IPC: G05D3/12
Filed: 2000-04-28
Abstract: Piezoelectric elements or similar microactuators perform fine positioning in a system including at least two masses bendably coupled to a larger body. A servo controller receives a position signal from a sensor on the first mass, from which it generates a signal to control microactuators coupling other masses to the body. The movement of the other masses thereby exerts a controlled reactive force upon the body and upon the first mass. Examples include disc drive systems in which the reactive forces are used to counteract one or more unwanted excitations in an actuator body or actuator arm.
