Title: Light transmission adjustable spectacles
Inventor: LIN CHWEN-YIH
IPC: G02C7/12
Filed: 1996-01-02
Abstract: A light transmission adjustable spectacle structure comprises for each lens set thereof a fixed polaroid lens and a rotatable polaroid lens which has a number of non-polarized aperture-like areas formed thereon so that when the rotatable lens is rotated relative to the fixed lens to have the polarization directions thereof normal to each other, light is only allowed to pass through the apertures of the rotatable lens. This significantly cuts down the transmission of light through the lens set. In addition,  by  suitably  selecting  the  size  of  the aperture-like areas, the depth of focus of retinal image occurring to a wearer of  the  spectacles  is properly increased to provide a more clear view to the wearer.

Abstract: Un rasoir comporte un manche (1) portant une lame (2) démontable, et un distributeur (3) pouvant contenir des lames neuves et usagées. Ce distributeur comprend une rangée de lames parallèles dont les faces arrière sont dirigées vers le haut. Des rails (24) disposés sur les faces arrière de ces lames définissent une glissière qui coopère avec des éléments glissants complémentaires (31) placés sur le manche. Ce dernier comporte des verrous (33) comprimés qui entrent dans des rainures (26) disposés sur les lames pour verrouiller ces dernières au manche. Pour ouvrir les verrous, des cames (34) qui leur sont couplées sont conçues pour être actionnées par le mouvement d'une lame, portée par le manche, qui vient buter sur une autre lame. Ce distributeur définit une position d'entrée, placée derrière la rangée de lames qui est stockée, ainsi qu'une position de distribution placée devant cette rangée de lames. Une lame usagée à remplacer est insérée dans le distributeur à la position d'entrée et déplacée vers l'avant pour faire avancer les lames stockées le long de ce distributeur de façon que la lame frontale parvienne en position de distribution. Les verrous de poignée s'ouvrent quand leurs cames sont actionnées par la lame contre laquelle la lame usagée vient en butée, et le manche est alors libre de glisser le long du distributeur en étant guidé par les lames jusqu'à ce qu'il se verrouille sur la lame frontale, placée en position de distribution, qu'on peut alors extraire du distributeur. Les lames contenues dans le distributeur sont ainsi distribuées successivement et finissent par être toutes remplacées par des lames usagées. On peut placer une barrière (42, 50, 60) dans le distributeur pour éviter que des lames usagées en ressortent et on peut la disposer de façon qu'une fois distribuée la dernière lame neuve, la position d'entrée est bloquée par une lame usagée pour exclure toute tentative d'insérer une autre lame usagée dans le distributeur.

Title: Battery capacity indicator
Inventor: CAMERON DAVID BRADLEY
IPC: G01R31/382
Filed: 1995-01-10
Abstract: This invention is a battery monitor and battery capacity indica-tor that uses a sense cell (22) in ad-dition to the main battery (10) to de-termine main battery remaining ca-pacity and depletion condition. A parameter of the sense cell is related to the main battery capacity so that the main battery will have a mini-mum capacity remaining when the sense cell parameter reaches a par-ticular value or crosses a particular threshold. In a preferred embodi-ment, the sense cell (22) is a battery which is identical and of the same manufacturing lot as the battery cell or cells (20) in the main battery pack (10). A current is drawn from the sense cell that is larger than the current being drawn from the main battery. When the sense cell (22) is fully depleted, the main battery (10) will have a remaining capacity whose magnitude depends on the re-lationship between the main battery current and the sense cell current.
