    • A lens system (46) that can be used in a digital camera includes, in sequence, a first lens element (20), a second lens element (30) and a third lens element (40). The first lens element is biconvex and includes a first spherical surface (22) and a second spherical surface (24). The second lens is concavo-convex and includes a first aspheric surface (32) and a second aspheric surface (34). The first aspheric surface is a diffractive surface. The third lens includes a wave-shaped third aspheric surface (42) and a wave-shaped fourth aspheric surface (44). The lens has a compact volume and provides stable imaging performance and good image quality.

    • A portable communication device includes a body (11) having a container (111) and a buffer room (115), and a plurality of fragrance releasing apparatuses (12) housed in the container. The body houses main circuitry therein. The buffer room communicates with the container and outside environment. The container also houses a plurality of electrical connectors therein. The electrical connectors are electrically connected with the main circuitry. Each fragrance releasing apparatus includes a vessel (121) with a nozzle (127). Each nozzle includes a heater (128) connecting with and being enabled by the main circuitry via the corresponding electrical connector. When the portable communication device receives an incoming call (or message), predetermined heaters are enabled by the main circuitry to release a fragrance corresponding to the caller (or sender).
    • 便携式通信装置包括具有容器(111)和缓冲室(115)的主体(11)和容纳在容器中的多个香味释放装置(12)。 车身内装有主电路。 缓冲室与容器和外界环境通信。 容器还在其中容纳多个电连接器。 电连接器与主电路电连接。 每个香味释放装置包括具有喷嘴(127)的容器(121)。 每个喷嘴包括通过相应的电连接器与主电路连接并由其启用的加热器(128)。 当便携式通信设备接收到来电(或消息)时,主电路启用预定的加热器以释放对应于呼叫者(或发送者)的香味。

    • A planar light source device (6) for a liquid crystal display device. The planar light source device includes a light source device (2) and a light guide plate (67). The light source device includes a light-emitting element (21), and an optical guiding member (20) that is hollow and has a reflective surface. The reflective surface receives light rays emitted by the light-emitting element, and guides the light rays out from a plurality of generally aligned through holes (23) defined in a front light-emitting surface (28) of the optical guiding member. The light guide plate has a light incident surface adjacent to the light source device. The planar light source device can greatly diminish possible dark regions on the light-emitting surface of the light guide plate, and provide uniform illumination for an LCD.
    • 一种用于液晶显示装置的平面光源装置(6)。 平面光源装置包括光源装置(2)和导光板(67)。 光源装置包括发光元件(21)和中空的具有反射表面的光导元件(20)。 反射面接受由发光元件发出的光线,并且将光线从限定在导光构件的前发光面(28)中的多个大致对准的通孔(23)引出。 导光板具有与光源装置相邻的光入射面。 平面光源装置可以大大减少导光板的发光面上的暗区,为LCD提供均匀的照明。
